17
00:00:48,600 --> 00:00:52,739
uh I remember back when I was working

18
00:00:51,239 --> 00:00:54,239
with Nikki and Amanda at the Australian

19
00:00:52,739 --> 00:00:56,640
Computing Academy

20
00:00:54,239 --> 00:00:58,980
um we came to pycon with the suggestion

21
00:00:56,640 --> 00:01:01,199
of a student Showcase in one of the

22
00:00:58,980 --> 00:01:03,120
years it was being organized and the

23
00:01:01,199 --> 00:01:04,680
pycon organizing committee took a risk

24
00:01:03,120 --> 00:01:06,600
uh decided that they were going to give

25
00:01:04,680 --> 00:01:08,280
it a go and ever since then it's been a

26
00:01:06,600 --> 00:01:10,200
key part of the program on the education

27
00:01:08,280 --> 00:01:12,000
specialist track day and I know everyone

28
00:01:10,200 --> 00:01:15,299
really enjoys it so it's absolutely

29
00:01:12,000 --> 00:01:17,400
phenomenal to be here and to see how the

30
00:01:15,299 --> 00:01:18,979
student showcase continues to thrive at

31
00:01:17,400 --> 00:01:22,020
this conference it really is exciting

32
00:01:18,979 --> 00:01:24,299
I'm here as the chief education officer

33
00:01:22,020 --> 00:01:26,340
at grock Academy for those of you who

34
00:01:24,299 --> 00:01:28,680
don't know who we are we're an education

35
00:01:26,340 --> 00:01:31,320
technology uh charitable not charitable

36
00:01:28,680 --> 00:01:33,240
not for profit and I'm going to give you

37
00:01:31,320 --> 00:01:34,560
a sense of what we do by starting with

38
00:01:33,240 --> 00:01:38,040
our mission

39
00:01:34,560 --> 00:01:41,700
um it's a pretty big audacious purpose

40
00:01:38,040 --> 00:01:43,740
this one what we are aiming to do and

41
00:01:41,700 --> 00:01:46,259
it's the whole reason that we establish

42
00:01:43,740 --> 00:01:48,540
the organization is to basically educate

43
00:01:46,259 --> 00:01:49,920
all all Learners and we don't mind you

44
00:01:48,540 --> 00:01:52,380
know how old you are what your

45
00:01:49,920 --> 00:01:54,479
background is in the transformative

46
00:01:52,380 --> 00:01:57,840
Computing skills knowledge and

47
00:01:54,479 --> 00:01:59,399
dispositions empowering everyone to meet

48
00:01:57,840 --> 00:02:02,579
the challenges and seize the

49
00:01:59,399 --> 00:02:05,579
opportunities of the future so our goal

50
00:02:02,579 --> 00:02:08,220
eventually is to eliminate the need for

51
00:02:05,579 --> 00:02:09,899
our existence but a big part of actually

52
00:02:08,220 --> 00:02:12,060
getting there and being able to make

53
00:02:09,899 --> 00:02:15,300
this happen is supporting teachers in

54
00:02:12,060 --> 00:02:18,060
schools so when the opportunity came to

55
00:02:15,300 --> 00:02:20,520
be a part of this event and to sponsor

56
00:02:18,060 --> 00:02:23,160
the education specialist track we jumped

57
00:02:20,520 --> 00:02:25,260
at the opportunity immediately and it's

58
00:02:23,160 --> 00:02:27,080
just so great to see so many people here

59
00:02:25,260 --> 00:02:29,760
sharing what they're doing with python

60
00:02:27,080 --> 00:02:32,879
how they're educating the students of

61
00:02:29,760 --> 00:02:34,319
Australia and to be here and see some of

62
00:02:32,879 --> 00:02:36,480
the amazing work that's happening in our

63
00:02:34,319 --> 00:02:40,280
classrooms so if you don't know what we

64
00:02:36,480 --> 00:02:42,120
do we offer our online automated

65
00:02:40,280 --> 00:02:44,760
feedback

66
00:02:42,120 --> 00:02:46,860
um activities for students and we offer

67
00:02:44,760 --> 00:02:48,780
those for free I'll talk a little bit

68
00:02:46,860 --> 00:02:50,099
about more about that in a moment we

69
00:02:48,780 --> 00:02:51,720
have a number of unplugged activities

70
00:02:50,099 --> 00:02:53,580
and we've got a lot of expertise in the

71
00:02:51,720 --> 00:02:56,819
team around professional learning and

72
00:02:53,580 --> 00:02:58,319
teacher development as well so we

73
00:02:56,819 --> 00:03:00,540
provide dedicated customer support to

74
00:02:58,319 --> 00:03:02,640
all of our customers it is free and

75
00:03:00,540 --> 00:03:04,500

received through our industry Partners

77
00:03:04,500 --> 00:03:09,060
in particular wise Tech Global and that

78
00:03:06,959 --> 00:03:10,819
what that means is that no matter where

79
00:03:09,060 --> 00:03:13,379
you're teaching whether you're a student

80
00:03:10,819 --> 00:03:15,000
if you are someone who's out there

81
00:03:13,379 --> 00:03:18,300
working in industry and wants to do some

82
00:03:15,000 --> 00:03:21,060
work with the schools in your area or

83
00:03:18,300 --> 00:03:22,800
provide some mentoring and support there

84
00:03:21,060 --> 00:03:25,080
is no cost to access any of the

85
00:03:22,800 --> 00:03:26,220
materials on the platform so if you are

86
00:03:25,080 --> 00:03:27,900
interested in learning a little bit more

87
00:03:26,220 --> 00:03:30,840
about what we do please come and see me

88
00:03:27,900 --> 00:03:32,640
at some stage we'll find a way to give

89
00:03:30,840 --> 00:03:34,080
you the tools you need or that you're

90
00:03:32,640 --> 00:03:37,080
after to support the work that's going

91
00:03:34,080 --> 00:03:39,000
on in schools and yeah just we're really

92
00:03:37,080 --> 00:03:41,599
excited to be a part of the event that's

well I'm happy to welcome Bianca so

106
00:04:12,420 --> 00:04:16,739
she's going to be talking

107
00:04:15,000 --> 00:04:19,500
magic happening over there about Music

108
00:04:16,739 --> 00:04:21,959
Mate which is a python-based music

109
00:04:19,500 --> 00:04:25,199
recommendation system Bianca has been

110
00:04:21,959 --> 00:04:27,660
programming for about nine years

111
00:04:25,199 --> 00:04:30,000
um her favorite emoji is the goose Emoji

112
00:04:27,660 --> 00:04:32,100
now this is a relevant question back in

113
00:04:30,000 --> 00:04:34,199
the day because we used to I used to

114
00:04:32,100 --> 00:04:36,060
have to do the intros via on online but

115
00:04:34,199 --> 00:04:38,040
I don't have please don't make me do the

116
00:04:36,060 --> 00:04:39,479
honk I don't

117
00:04:38,040 --> 00:04:41,639
um and she recently learned that the

118
00:04:39,479 --> 00:04:42,900
process that a translator goes through

119
00:04:41,639 --> 00:04:44,220
to create I really should have read this

120
00:04:42,900 --> 00:04:46,500
before convert a high-level language

121
00:04:44,220 --> 00:04:49,080
like python into machine load code that

122
00:04:46,500 --> 00:04:51,919
can understand that is fantastic uh

123
00:04:49,080 --> 00:04:51,919
welcome go yes

124
00:04:52,380 --> 00:04:55,520
yeah thank you

125
00:04:56,300 --> 00:05:03,240
now it's on awesome all right so Music

126
00:05:00,600 --> 00:05:05,820
Mate hi hi I'm Bianca

127
00:05:03,240 --> 00:05:07,740
um first of all uh you should know that

128
00:05:05,820 --> 00:05:09,780
I oh my notes on it on here but that's

129
00:05:07,740 --> 00:05:10,860
fine uh we'll free ball

130
00:05:09,780 --> 00:05:14,520
um

131
00:05:10,860 --> 00:05:17,160
um so I am a music like addict and I

132
00:05:14,520 --> 00:05:18,960
also love Python and giving me free

133
00:05:17,160 --> 00:05:21,240
choice is a really bad idea

134
00:05:18,960 --> 00:05:23,820
um so I made Music Mate for my ipt

135
00:05:21,240 --> 00:05:25,440
information processes technology

136
00:05:23,820 --> 00:05:27,539
um final project

137
00:05:25,440 --> 00:05:30,840
um yeah

138
00:05:27,539 --> 00:05:33,840
um basically we had to make a program

139
00:05:30,840 --> 00:05:35,759
that used a database to do literally

140
00:05:33,840 --> 00:05:37,860
anything we wanted

141
00:05:35,759 --> 00:05:40,860
um so I knew that I wanted to make a

142
00:05:37,860 --> 00:05:42,600
music system uh so Music Mate is the

143
00:05:40,860 --> 00:05:45,600
system I made

144
00:05:42,600 --> 00:05:47,639
um so it's a web app that helps to find

145
00:05:45,600 --> 00:05:49,620
and create playlists based on like a

146
00:05:47,639 --> 00:05:52,860
user's Spotify information

147
00:05:49,620 --> 00:05:56,340
um it uses Spotify which is like a API

148
00:05:52,860 --> 00:05:59,699
library for Spotify the Spotify API uses

149
00:05:56,340 --> 00:06:01,979
pythog 2 and it uses flask and I'm gonna

150
00:05:59,699 --> 00:06:03,419
have a bit of a disclaimer there's a lot

151
00:06:01,979 --> 00:06:04,919
that I'd love to talk about but 10

152
00:06:03,419 --> 00:06:08,160
minutes is a really short amount of time

153
00:06:04,919 --> 00:06:09,600
to speak so that's my GitHub There's the

154
00:06:08,160 --> 00:06:11,400
link to the repository if anyone wants

155
00:06:09,600 --> 00:06:15,060
to see it

156
00:06:11,400 --> 00:06:17,880
um yeah so basically the first step to

157
00:06:15,060 --> 00:06:19,320
my project is it needs to get like the

158
00:06:17,880 --> 00:06:21,539
user's track information there's two

159
00:06:19,320 --> 00:06:22,979
sides that's getting the making your own

160
00:06:21,539 --> 00:06:24,720
playlist and finding someone else's

161
00:06:22,979 --> 00:06:26,039
playlist so in order to make your own

162
00:06:24,720 --> 00:06:28,979
you need to get

163
00:06:26,039 --> 00:06:30,660
your first tracks so there are three

164
00:06:28,979 --> 00:06:32,220
there's get getting recent tracks

165
00:06:30,660 --> 00:06:33,600
getting top tracks and getting tracks

166
00:06:32,220 --> 00:06:36,720
from your library they're all basically

167
00:06:33,600 --> 00:06:39,180
the same essentially I make a call to

168
00:06:36,720 --> 00:06:41,100
the API and then it gives me this like

169
00:06:39,180 --> 00:06:43,560
massive response which is really

170
00:06:41,100 --> 00:06:45,900
annoying to go through

171
00:06:43,560 --> 00:06:48,780
um to like by myself which is why I make

172
00:06:45,900 --> 00:06:51,240
my own smaller little dictionary that

173
00:06:48,780 --> 00:06:53,580
has lists and things inside it kind of

174
00:06:51,240 --> 00:06:55,319
looks like Json but it's not it's python

175
00:06:53,580 --> 00:06:56,460
don't be fooled

176
00:06:55,319 --> 00:07:00,360
um

177
00:06:56,460 --> 00:07:02,940
uh so essentially I just I make this I

178
00:07:00,360 --> 00:07:06,300
use uh Spotify for this and then I

179
00:07:02,940 --> 00:07:07,740
return it to my flask main line

180
00:07:06,300 --> 00:07:10,620
um and then I do a similar thing for

181
00:07:07,740 --> 00:07:13,080
getting uh user playlist

182
00:07:10,620 --> 00:07:14,880
um so I do this fun little thing called

183
00:07:13,080 --> 00:07:17,160
stealing user data

184
00:07:14,880 --> 00:07:18,060
um it sounds a bit more serious than it

185
00:07:17,160 --> 00:07:21,300
is

186
00:07:18,060 --> 00:07:24,660
um essentially I in order to service the

187
00:07:21,300 --> 00:07:28,139
second half of my uh project is I need

188
00:07:24,660 --> 00:07:29,880
to find uh songs that have fine

189
00:07:28,139 --> 00:07:32,039
playlists that have a specific song in

190
00:07:29,880 --> 00:07:34,560
them so I thought why not if I'm already

191
00:07:32,039 --> 00:07:36,300
handling what's in a playlist and

192
00:07:34,560 --> 00:07:37,259
playlists in general why not just do it

193
00:07:36,300 --> 00:07:38,940
in this

194
00:07:37,259 --> 00:07:41,880
um do I tell the user I do this no

195
00:07:38,940 --> 00:07:43,860
should I probably will I know

196
00:07:41,880 --> 00:07:46,259
um

197
00:07:43,860 --> 00:07:48,840
um so essentially similar processes

198
00:07:46,259 --> 00:07:50,400
before call the API make my own little

199
00:07:48,840 --> 00:07:54,539
Json

200
00:07:50,400 --> 00:07:57,900
um and then I call a second uh function

201
00:07:54,539 --> 00:08:00,539
to just get the items and then put it in

202
00:07:57,900 --> 00:08:04,319
my postgres database

203
00:08:00,539 --> 00:08:06,599
um onto databases I've got four tables

204
00:08:04,319 --> 00:08:09,720
um I've got one for like a main tracks

205
00:08:06,599 --> 00:08:12,000
our main playlist one to like log user

206
00:08:09,720 --> 00:08:14,099
songs and want to log the songs that are

207
00:08:12,000 --> 00:08:15,599
in playlists

208
00:08:14,099 --> 00:08:18,060
um was there anything I wanted to say

209
00:08:15,599 --> 00:08:19,280
about this not really I had to use um

210
00:08:18,060 --> 00:08:21,539
postgres

211
00:08:19,280 --> 00:08:23,220
I didn't have to but I wanted to because

212
00:08:21,539 --> 00:08:26,460
that's how I knew that's how I knew how

213
00:08:23,220 --> 00:08:28,919
to do SQL so and databasing and stuff so

214
00:08:26,460 --> 00:08:30,479
I did that essentially this is the pi

215
00:08:28,919 --> 00:08:33,120
sock that I have

216
00:08:30,479 --> 00:08:36,479
um it's very similar to normal SQL I

217
00:08:33,120 --> 00:08:40,020
just kind of write my SQL statement and

218
00:08:36,479 --> 00:08:44,039
then I fetch everything and then if the

219
00:08:40,020 --> 00:08:46,140
if the playlist uh if the playlist TR uh

220
00:08:44,039 --> 00:08:48,720
the track wasn't in the playlist or I

221
00:08:46,140 --> 00:08:51,360
didn't have it registered then I would

222
00:08:48,720 --> 00:08:55,200
add it if not I'd Skip and then I'd

223
00:08:51,360 --> 00:08:58,920
return a oh this is finding anyway I'd

224
00:08:55,200 --> 00:09:01,680
find a I'd find it if I had it for the

225
00:08:58,920 --> 00:09:03,420
track I'm losing my track if I thought

226
00:09:01,680 --> 00:09:06,000
but that's fine

227
00:09:03,420 --> 00:09:09,420
um essentially I'd return or playlist

228
00:09:06,000 --> 00:09:11,220
IDs that have a specific track ID in

229
00:09:09,420 --> 00:09:12,360
them I only store the playlist IDs

230
00:09:11,220 --> 00:09:15,360
because that's all I need to store

231
00:09:12,360 --> 00:09:17,640
Spotify has these like massive beefy API

232
00:09:15,360 --> 00:09:19,260
servers I don't I have this little

233
00:09:17,640 --> 00:09:21,600
computer

234
00:09:19,260 --> 00:09:23,160
um so I kind of I give it all the help

235
00:09:21,600 --> 00:09:26,279
it needs

236
00:09:23,160 --> 00:09:28,200
um so python URL uis are really weird um

237
00:09:26,279 --> 00:09:30,240
at least to me

238
00:09:28,200 --> 00:09:32,940
um so I didn't enter up until like three

239
00:09:30,240 --> 00:09:34,440
months ago I had never actually made a

240
00:09:32,940 --> 00:09:35,700
UI before

241
00:09:34,440 --> 00:09:37,740
um I also take software design

242
00:09:35,700 --> 00:09:40,440
development um and I need I use like

243
00:09:37,740 --> 00:09:43,980
tikenta and app jar

244
00:09:40,440 --> 00:09:45,959
um for that uh but that kind of wasn't

245
00:09:43,980 --> 00:09:49,080
really helpful it kind of looked older

246
00:09:45,959 --> 00:09:51,360
than I did so I didn't want to use it

247
00:09:49,080 --> 00:09:54,240
um so then um my software teacher

248
00:09:51,360 --> 00:09:56,459
suggested I used um Anvil which is like

249
00:09:54,240 --> 00:09:57,959
an online form creator that kind of that

250
00:09:56,459 --> 00:10:00,480
didn't let me use external libraries

251
00:09:57,959 --> 00:10:02,040
unless I paid for it and I'm poor so I

252
00:10:00,480 --> 00:10:05,100
didn't want to

253
00:10:02,040 --> 00:10:07,040
um and then so then I moved on to abstra

254
00:10:05,100 --> 00:10:10,560
Dash and that had similar

255
00:10:07,040 --> 00:10:13,500
limitations uh then I tried uh Django

256
00:10:10,560 --> 00:10:15,480
and that was really hard and very scary

257
00:10:13,500 --> 00:10:17,220
um so I abandoned that with a week left

258
00:10:15,480 --> 00:10:19,560
and then I tried flask some of my

259
00:10:17,220 --> 00:10:22,260
friends recommended flask and that

260
00:10:19,560 --> 00:10:24,420
worked awesomely I went to ncss earlier

261
00:10:22,260 --> 00:10:26,459
this year and then we used flask there

262
00:10:24,420 --> 00:10:28,740
and so that was really helpful I kind of

263
00:10:26,459 --> 00:10:30,600
already had a base understanding and

264
00:10:28,740 --> 00:10:32,540
I've been doing HTML for like nine years

265
00:10:30,600 --> 00:10:35,339
so it wasn't too much of a problem

266
00:10:32,540 --> 00:10:37,260
essentially this is my routing

267
00:10:35,339 --> 00:10:38,399
um my like creating playlist and adding

268
00:10:37,260 --> 00:10:39,839
tracks to playlist is the most

269
00:10:38,399 --> 00:10:41,580
interesting

270
00:10:39,839 --> 00:10:44,940
um I essentially

271
00:10:41,580 --> 00:10:46,320
get I I have two ways you could go you

272
00:10:44,940 --> 00:10:47,880
could either click on a playlist to add

273
00:10:46,320 --> 00:10:49,440
it to a pre-existing playlist or you can

274
00:10:47,880 --> 00:10:52,440
make your own

275
00:10:49,440 --> 00:10:53,820
um and then essentially if you're if

276
00:10:52,440 --> 00:10:56,519
you've clicked then you know it's a post

277
00:10:53,820 --> 00:10:59,399
statement and I can just uh get all the

278
00:10:56,519 --> 00:11:02,160
information from the final or from the

279
00:10:59,399 --> 00:11:05,160
last page otherwise I can use Global

280
00:11:02,160 --> 00:11:07,980
variables which I've defined in the

281
00:11:05,160 --> 00:11:09,899
creating which you can vaguely see

282
00:11:07,980 --> 00:11:14,399
um and then I redirect the user to the

283
00:11:09,899 --> 00:11:16,680
ads playlist and then add a uh basically

284
00:11:14,399 --> 00:11:20,040
again if it's a post it knows that it's

285
00:11:16,680 --> 00:11:22,860
just going to get it from the last if

286
00:11:20,040 --> 00:11:25,500
not then it can get from the global and

287
00:11:22,860 --> 00:11:29,459
then it can add use the API to add it in

288
00:11:25,500 --> 00:11:33,959
and then render some nice HTML so demo

289
00:11:29,459 --> 00:11:35,940
time hopefully I can do this I did it

290
00:11:33,959 --> 00:11:37,320
did break like not 10 seconds ago but

291
00:11:35,940 --> 00:11:38,040
that's fine

292
00:11:37,320 --> 00:11:39,959
um

293
00:11:38,040 --> 00:11:43,160
I don't have that going I didn't test

294
00:11:39,959 --> 00:11:43,160
this I'm sorry AV

295
00:11:44,100 --> 00:11:47,940
um

296
00:11:45,000 --> 00:11:50,640
oh well I've got a video why not

297
00:11:47,940 --> 00:11:52,200
and this is why my ipt teacher sold me

298
00:11:50,640 --> 00:11:54,260
to do videos

299
00:11:52,200 --> 00:11:54,260
um

300
00:11:54,420 --> 00:11:58,279
I think I may have broken it

301
00:12:00,000 --> 00:12:05,619
okay

302
00:12:02,460 --> 00:12:05,619
[Applause]

303
00:12:06,660 --> 00:12:11,399
handy dandy video so essentially this is

304
00:12:09,720 --> 00:12:13,440
uh you need to click on a button to log

305
00:12:11,399 --> 00:12:15,480
in it logs in let's do playlists by

306
00:12:13,440 --> 00:12:16,980
recommendation

307
00:12:15,480 --> 00:12:19,800
policy anchor please click on this

308
00:12:16,980 --> 00:12:21,300
faster oh that's why it takes 15 seconds

309
00:12:19,800 --> 00:12:24,000
to load

310
00:12:21,300 --> 00:12:27,000
um because I have to Loop through 75

311
00:12:24,000 --> 00:12:29,220
objects of the 75 items in a dictionary

312
00:12:27,000 --> 00:12:31,140
which takes a really long time because

313
00:12:29,220 --> 00:12:33,360
of course it does

314
00:12:31,140 --> 00:12:34,500
um yay and you can see horizontal

315
00:12:33,360 --> 00:12:37,019
scrolling

316
00:12:34,500 --> 00:12:38,459
um my favorite I love CSS with all my

317
00:12:37,019 --> 00:12:41,519
heart

318
00:12:38,459 --> 00:12:42,899
um so I spent a bit too long on it

319
00:12:41,519 --> 00:12:44,760
um

320
00:12:42,899 --> 00:12:47,399
um so basically you can once you click

321
00:12:44,760 --> 00:12:49,500
on a track you can scroll through all

322
00:12:47,399 --> 00:12:51,420
the recommendations select all fancy

323
00:12:49,500 --> 00:12:52,680
JavaScript we love I stole it from stack

324
00:12:51,420 --> 00:12:53,660
Overflow

325
00:12:52,680 --> 00:12:56,399
um

326
00:12:53,660 --> 00:12:58,260
and then again it takes a bit long to

327
00:12:56,399 --> 00:12:59,760
quite a while to load

328
00:12:58,260 --> 00:13:01,800
um because it's getting all of your

329
00:12:59,760 --> 00:13:05,100
playlist information

330
00:13:01,800 --> 00:13:08,100
but once it's done it does it will

331
00:13:05,100 --> 00:13:10,139
list all your playlists

332
00:13:08,100 --> 00:13:12,300
um which is cool

333
00:13:10,139 --> 00:13:16,079
um and then you can make your own

334
00:13:12,300 --> 00:13:18,600
um I did misspell pycon twice but that's

335
00:13:16,079 --> 00:13:20,399
fine I put a b instead of a p

336
00:13:18,600 --> 00:13:21,480
I don't know how I did that

337
00:13:20,399 --> 00:13:23,100
um they're really far away on the

338
00:13:21,480 --> 00:13:25,560
keyboard if you want you can make it a

339
00:13:23,100 --> 00:13:27,480
public or a private playlist and then

340
00:13:25,560 --> 00:13:29,940
you can create it

341
00:13:27,480 --> 00:13:32,160
um now this is where my technical

342
00:13:29,940 --> 00:13:34,019
abilities are limited because it shares

343
00:13:32,160 --> 00:13:36,480
it I'm supposed to have Spotify up here

344
00:13:34,019 --> 00:13:37,500
but I didn't screen record that so let's

345
00:13:36,480 --> 00:13:39,000
skip

346
00:13:37,500 --> 00:13:41,220
um

347
00:13:39,000 --> 00:13:43,760
um okay well I can't skip

348
00:13:41,220 --> 00:13:43,760
awesome

349
00:13:44,630 --> 00:13:48,330
[Music]

350
00:13:45,230 --> 00:13:48,330
[Applause]

351
00:13:51,740 --> 00:13:58,519
amazing okay well the Applause cards can

352
00:13:55,079 --> 00:13:58,519
show on excellent okay

353
00:13:58,740 --> 00:14:03,360
I I didn't realize we were going to have

354
00:14:00,959 --> 00:14:05,519
a crossover to the API track as well

355
00:14:03,360 --> 00:14:09,019
that's amazing oh I'm sorry I forgot the

356
00:14:05,519 --> 00:14:12,660
Hat I'm sorry yes okay

357
00:14:09,019 --> 00:14:14,820

360
00:14:18,120 --> 00:14:24,899

enough

369
00:14:38,210 --> 00:14:41,359

um today I'm going to talk about how I

373
00:14:50,300 --> 00:14:55,040
automated my attendance during lockdown

374
00:14:56,040 --> 00:15:01,139
um this is for educational purposes so

375
00:14:58,500 --> 00:15:03,779
if any anyone yeah calls me out on this

376
00:15:01,139 --> 00:15:05,699
I uh is purely hypothetical

377
00:15:03,779 --> 00:15:08,279
all right so background information I'm

378
00:15:05,699 --> 00:15:11,220
sure you guys know but in 2020 and 2021

379
00:15:08,279 --> 00:15:13,740
our schools move to online learning also

380
00:15:11,220 --> 00:15:15,779
during that time that right released a

381
00:15:13,740 --> 00:15:17,220
new FPS game called Battle Run I liked

382
00:15:15,779 --> 00:15:19,399
it a lot so you can see where this is

383
00:15:17,220 --> 00:15:19,399
going

384
00:15:19,560 --> 00:15:25,560
uh yeah so in particular my school had a

385
00:15:23,399 --> 00:15:29,040
attendance form it was a it's a Google

386
00:15:25,560 --> 00:15:32,399
form and like looks something like this

387
00:15:29,040 --> 00:15:34,620
uh yes every period you need you need to

388
00:15:32,399 --> 00:15:36,899
fill this in and I really it's really

389
00:15:34,620 --> 00:15:38,940
annoying I didn't like it I wanted to

390
00:15:36,899 --> 00:15:41,940
take naps play video games

391
00:15:38,940 --> 00:15:44,100
um so so yeah hence the

392
00:15:41,940 --> 00:15:46,980
hence the automation

393
00:15:44,100 --> 00:15:48,720
so the first thing I did was to reverse

394
00:15:46,980 --> 00:15:50,519
engineer the form like to make my own

395
00:15:48,720 --> 00:15:52,320
version of the phone so I can like play

396
00:15:50,519 --> 00:15:55,440
around and test with it uh you can see

397
00:15:52,320 --> 00:15:57,000
there's 41 responses so it adds a lot of

398
00:15:55,440 --> 00:16:01,019
testing

399
00:15:57,000 --> 00:16:02,579
um yeah so so when you own the form you

400
00:16:01,019 --> 00:16:05,040
can make a

401
00:16:02,579 --> 00:16:06,540
pre-filled link that's the second thing

402
00:16:05,040 --> 00:16:07,500
I did

403
00:16:06,540 --> 00:16:10,019
um

404
00:16:07,500 --> 00:16:12,060
the the link of it is the pre-filled

405
00:16:10,019 --> 00:16:14,940
link that comes out uh

406
00:16:12,060 --> 00:16:16,800
and particularly do you want to pay

407
00:16:14,940 --> 00:16:18,000
attention to the purple part um

408
00:16:16,800 --> 00:16:21,240
everything that comes after the question

409
00:16:18,000 --> 00:16:23,699
mark so you can pretty much guess like

410
00:16:21,240 --> 00:16:26,699
I'll go back but oh no no

411
00:16:23,699 --> 00:16:28,440
like they correspond to each entry So

412
00:16:26,699 --> 00:16:30,180
like

413
00:16:28,440 --> 00:16:32,699
um the things that come after the equal

414
00:16:30,180 --> 00:16:34,800
signs are the answers to the entries but

415
00:16:32,699 --> 00:16:36,980
um what we don't know is what the

416
00:16:34,800 --> 00:16:40,680
numbers are like the IDS of each entry

417
00:16:36,980 --> 00:16:44,040
but luckily stack Overflow has the

418
00:16:40,680 --> 00:16:47,120
answer and yeah I'm not the first person

419
00:16:44,040 --> 00:16:51,600
to think of this you know so

420
00:16:47,120 --> 00:16:53,519
uh great like like-minded people

421
00:16:51,600 --> 00:16:57,480
um so one of the answers

422
00:16:53,519 --> 00:17:01,019
as the solution which is yeah inspect

423
00:16:57,480 --> 00:17:01,920
element yes

424
00:17:01,019 --> 00:17:03,600
um

425
00:17:01,920 --> 00:17:06,900
yeah so that's what I did for each one

426
00:17:03,600 --> 00:17:09,600
of them and I right clicked inspect and

427
00:17:06,900 --> 00:17:11,880
I copied the ID in

428
00:17:09,600 --> 00:17:14,819
uh just side note there's a lot of

429
00:17:11,880 --> 00:17:17,880
entries so I'll go back but

430
00:17:14,819 --> 00:17:20,400
uh basically we have two weeks we have

431
00:17:17,880 --> 00:17:21,720
five days and we have six periods so

432
00:17:20,400 --> 00:17:23,640
each one of them has different entries

433
00:17:21,720 --> 00:17:27,240
so that's like

434
00:17:23,640 --> 00:17:29,840
um pretty sure it's around 60 entries uh

435
00:17:27,240 --> 00:17:32,460
that's what I need to to to

436
00:17:29,840 --> 00:17:34,080
figure out but if you think about like

437
00:17:32,460 --> 00:17:36,240
the people who made the forms they're

438
00:17:34,080 --> 00:17:38,580
also like six years in the school so

439
00:17:36,240 --> 00:17:41,340
that's like unlucky for them they need

440
00:17:38,580 --> 00:17:42,000
to make all those forms yeah but these

441
00:17:41,340 --> 00:17:45,120
are

442
00:17:42,000 --> 00:17:46,500
order IDs that I painstakingly copied

443
00:17:45,120 --> 00:17:49,320
out

444
00:17:46,500 --> 00:17:52,380
um yeah and then and then it's pretty

445
00:17:49,320 --> 00:17:54,900
easy from there you just

446
00:17:52,380 --> 00:17:56,820
after the question about so when I coded

447
00:17:54,900 --> 00:17:59,280
this I didn't have any like I was a

448
00:17:56,820 --> 00:18:01,620
beginner at coding so this is

449
00:17:59,280 --> 00:18:04,679
like I just this is just string

450
00:18:01,620 --> 00:18:08,340
concatenation I just you know added them

451
00:18:04,679 --> 00:18:11,299
to the back of the form URL it's yes up

452
00:18:08,340 --> 00:18:13,500
till now this is all very like usual

453
00:18:11,299 --> 00:18:15,299
this is what you learn in Python you

454
00:18:13,500 --> 00:18:17,160
know when you start learning python it's

455
00:18:15,299 --> 00:18:20,520
pretty basic

456
00:18:17,160 --> 00:18:22,799
um but so yeah so what comes out is the

457
00:18:20,520 --> 00:18:24,000
URL which is which is nice you know I

458
00:18:22,799 --> 00:18:25,679
just need to now all I need to do is

459
00:18:24,000 --> 00:18:29,160
just click on it and um

460
00:18:25,679 --> 00:18:32,120
out comes the pre-filled link uh I can

461
00:18:29,160 --> 00:18:32,120
demo I think

462
00:18:41,820 --> 00:18:48,480
uh yeah and I'll just click on this and

463
00:18:46,140 --> 00:18:50,520
oh

464
00:18:48,480 --> 00:18:54,600
but it is something for you but like you

465
00:18:50,520 --> 00:18:54,600
know you have to click on it still uh

466
00:18:55,090 --> 00:18:58,880
[Music]

467
00:18:56,480 --> 00:19:01,860
yeah so

468
00:18:58,880 --> 00:19:02,820
yeah so it's still kind of annoying

469
00:19:01,860 --> 00:19:05,100
because you still need to click on the

470
00:19:02,820 --> 00:19:06,660
link and you still need to uh you need

471
00:19:05,100 --> 00:19:07,320
there's still manual input to it you

472
00:19:06,660 --> 00:19:08,820
know

473
00:19:07,320 --> 00:19:11,220
um so there's a second attempt this is

474
00:19:08,820 --> 00:19:12,960
an improvement on the first one um see I

475
00:19:11,220 --> 00:19:14,400
didn't know anything for I don't know my

476
00:19:12,960 --> 00:19:15,840
my thought process is I need to click on

477
00:19:14,400 --> 00:19:18,000
the link and I need to enter the link so

478
00:19:15,840 --> 00:19:20,760
why do I just how do I open a link in

479
00:19:18,000 --> 00:19:22,260
Python how do I send input on python

480
00:19:20,760 --> 00:19:23,700
which is which led to this you know I

481
00:19:22,260 --> 00:19:28,559
just opened the link with my computer

482
00:19:23,700 --> 00:19:30,660
and then I yeah enter enter the link

483
00:19:28,559 --> 00:19:32,160
um but this is still pretty annoying

484
00:19:30,660 --> 00:19:33,840
because I'm playing video games right I

485
00:19:32,160 --> 00:19:35,880
don't wanna I don't want to open it in

486
00:19:33,840 --> 00:19:40,200
the browser it's gonna distract from my

487
00:19:35,880 --> 00:19:43,200
experience so the third attempt is um

488
00:19:40,200 --> 00:19:46,080
oh [ __ ] at this point at this point I

489
00:19:43,200 --> 00:19:48,120
learned about something called requests

490
00:19:46,080 --> 00:19:49,679
um I'm pretty sure you guys are familiar

491
00:19:48,120 --> 00:19:52,740
with it but everything is apparently

492
00:19:49,679 --> 00:19:55,740
made out of HTTP requests and Google

493
00:19:52,740 --> 00:19:57,539
forms are no different so the things

494
00:19:55,740 --> 00:19:59,400
after the question marks I found was

495
00:19:57,539 --> 00:20:02,460
actually like what they call like a data

496
00:19:59,400 --> 00:20:05,220
payload and you can

497
00:20:02,460 --> 00:20:06,900
you can use request to post to yeah you

498
00:20:05,220 --> 00:20:09,059
can put YouTube's request supposed to

499
00:20:06,900 --> 00:20:11,059
submit the form instead

500
00:20:09,059 --> 00:20:11,059
um

501
00:20:11,640 --> 00:20:15,000
yeah so it's pretty much the same thing

502
00:20:13,980 --> 00:20:16,500
except

503
00:20:15,000 --> 00:20:18,000
the the entries are different because

504
00:20:16,500 --> 00:20:21,000
there's a test form and there's like the

505
00:20:18,000 --> 00:20:22,559
actual form but yeah yeah you see how

506
00:20:21,000 --> 00:20:25,320
they correspond

507
00:20:22,559 --> 00:20:26,640
um but this doesn't work unluckily

508
00:20:25,320 --> 00:20:28,620
because

509
00:20:26,640 --> 00:20:30,720
uh

510
00:20:28,620 --> 00:20:32,460
you need to have a you need to be logged

511
00:20:30,720 --> 00:20:34,620
into your education email when you're

512
00:20:32,460 --> 00:20:36,299
submitting the actual form so it works

513
00:20:34,620 --> 00:20:38,400
my test form because I don't have I made

514
00:20:36,299 --> 00:20:39,600
it with my own email but for for the

515
00:20:38,400 --> 00:20:41,880
actual attendance form you need to be

516
00:20:39,600 --> 00:20:42,480
logged into your education email

517
00:20:41,880 --> 00:20:44,580
um

518
00:20:42,480 --> 00:20:47,039
which is unlucky but you know maybe in

519
00:20:44,580 --> 00:20:49,919
uni when I have I have another Google

520
00:20:47,039 --> 00:20:52,200
form I can just submit it with requests

521
00:20:49,919 --> 00:20:54,240
um but not for this one so

522
00:20:52,200 --> 00:20:57,059
the fourth attempt so my dad told me

523
00:20:54,240 --> 00:20:58,919
about something called selenium uh which

524
00:20:57,059 --> 00:20:59,940
is which is great look at the tagline

525
00:20:58,919 --> 00:21:01,320
you know

526
00:20:59,940 --> 00:21:03,720
um what you do with that power is

527
00:21:01,320 --> 00:21:05,340
entirely up to you borrowing web-based

528
00:21:03,720 --> 00:21:06,960
and administration tasks can be

529
00:21:05,340 --> 00:21:09,900
automated that's great yeah that's what

530
00:21:06,960 --> 00:21:13,980
I'm looking for uh yeah so

531
00:21:09,900 --> 00:21:15,630
that leads to the final product Oh wait

532
00:21:13,980 --> 00:21:17,520
um oh there we go

533
00:21:15,630 --> 00:21:19,500
[Music]

534
00:21:17,520 --> 00:21:21,120
let me just

535
00:21:19,500 --> 00:21:23,340
die yeah so the final product I just

536
00:21:21,120 --> 00:21:25,380
basically log in on the automated

537
00:21:23,340 --> 00:21:28,140
browser log into my email on automated

538
00:21:25,380 --> 00:21:32,539
browser and go take my pre-filled link

539
00:21:28,140 --> 00:21:32,539
and submit it so here it is

540
00:21:46,320 --> 00:21:49,100
yeah I'd say

541
00:21:58,320 --> 00:22:02,240
yeah it's been recorded yeah

542
00:22:06,000 --> 00:22:09,840
I just just so it's just a note like

543
00:22:08,400 --> 00:22:11,760
this is for demonstration purposes but

544
00:22:09,840 --> 00:22:13,440
you can you can have you can disable the

545
00:22:11,760 --> 00:22:14,820
GUI and it'll just run completely in the

546
00:22:13,440 --> 00:22:17,400
background so that's great I can just

547
00:22:14,820 --> 00:22:22,159
yeah I can just play my video again yeah

548
00:22:17,400 --> 00:22:22,159
yeah that's that's about it yeah

549
00:22:25,559 --> 00:22:29,760
try that at home I find myself in the

550
00:22:27,600 --> 00:22:31,140
fun situation of having to tell the

551
00:22:29,760 --> 00:22:33,419
children to remember that this is a

552
00:22:31,140 --> 00:22:35,950
family-friendly event no um okay thank

553
00:22:33,419 --> 00:22:37,760
you so much Sean Rebecca

554
00:22:35,950 --> 00:22:40,860
[Music]

555
00:22:37,760 --> 00:22:43,020
Rebecca's gonna talk about simple Python

556
00:22:40,860 --> 00:22:45,840
simulations she's been coding for about

557
00:22:43,020 --> 00:22:50,039
six years since year six her favorite

558
00:22:45,840 --> 00:22:52,320
emojis include the dancing emoji uh and

559
00:22:50,039 --> 00:22:54,360
she recently learned about the amazing

560
00:22:52,320 --> 00:22:56,280
interconnected fiber optic cables that

561
00:22:54,360 --> 00:22:58,080
make the internet work through the on

562
00:22:56,280 --> 00:22:59,820
the on the surface of the oceans and how

563
00:22:58,080 --> 00:23:01,799
cool is that

564
00:22:59,820 --> 00:23:04,080
I think that's pretty cool

565
00:23:01,799 --> 00:23:06,980
oh more stalling um I've run out of

566
00:23:04,080 --> 00:23:10,640
questions I went too fast okay okay

567
00:23:06,980 --> 00:23:10,640
we're running now

568
00:23:11,700 --> 00:23:17,820
um okay

569
00:23:13,080 --> 00:23:19,620
so first off uh yeah oh okay we're good

570
00:23:17,820 --> 00:23:21,960
um sorry the title sounds scary but I

571
00:23:19,620 --> 00:23:23,760
promise it's really not that fancy

572
00:23:21,960 --> 00:23:26,100
um so hi my name is Rebecca Lamont I go

573
00:23:23,760 --> 00:23:27,539
to Roseville College which is in Sydney

574
00:23:26,100 --> 00:23:29,159
um and I'm here with my friend Bianca

575
00:23:27,539 --> 00:23:31,320
today and today I'm going to talk about

576
00:23:29,159 --> 00:23:33,240
two projects that I recently completed

577
00:23:31,320 --> 00:23:34,380
as part of my year 12 assessments I

578
00:23:33,240 --> 00:23:36,840
don't think I'm gonna have time to go to

579
00:23:34,380 --> 00:23:38,340
the second unfortunately but um hope

580
00:23:36,840 --> 00:23:40,440
maybe I'll be able to show you a demo

581
00:23:38,340 --> 00:23:41,940
quickly at the end so for so first it

582
00:23:40,440 --> 00:23:43,200
was a seating sorter

583
00:23:41,940 --> 00:23:45,000
um which I made as part of my software

584
00:23:43,200 --> 00:23:46,140
design development major project and

585
00:23:45,000 --> 00:23:48,539
second of all

586
00:23:46,140 --> 00:23:51,000
um an oil drop experiment um simulation

587
00:23:48,539 --> 00:23:52,440
that I made as part of a physics task

588
00:23:51,000 --> 00:23:54,600
um I've got a timer here to cut myself

589
00:23:52,440 --> 00:23:56,400
off when it runs over so hopefully that

590
00:23:54,600 --> 00:23:58,440
doesn't happen I do have a penchant for

591
00:23:56,400 --> 00:24:00,000
doing that but anyway so first of all

592
00:23:58,440 --> 00:24:02,700
talking about seating sorta or the

593
00:24:00,000 --> 00:24:04,559
software thing so what is seating sorter

594
00:24:02,700 --> 00:24:06,240
so seating sorter is a tool made for

595
00:24:04,559 --> 00:24:08,159
events and event planners aiming to

596
00:24:06,240 --> 00:24:10,380
solve issues regarding seating guests at

597
00:24:08,159 --> 00:24:12,240
a table as every individual guest has

598
00:24:10,380 --> 00:24:13,860
personal preferences so this is aimed to

599
00:24:12,240 --> 00:24:16,020
like ease the load of like event

600
00:24:13,860 --> 00:24:17,340
planners and event hosts Etc as you know

601
00:24:16,020 --> 00:24:18,539
they want to be organizing everything

602
00:24:17,340 --> 00:24:20,700
else they don't want to be spending

603
00:24:18,539 --> 00:24:21,780
hours upon hours of organizing who wants

604
00:24:20,700 --> 00:24:24,360
to sit next to each other based on like

605
00:24:21,780 --> 00:24:25,919
petty feuds Etc so the program itself

606
00:24:24,360 --> 00:24:27,720
takes input of table shape and

607
00:24:25,919 --> 00:24:29,640
dimensions to produce a visualization of

608
00:24:27,720 --> 00:24:32,039
the table which then corresponds to the

609
00:24:29,640 --> 00:24:34,260
program's output and then it also takes

610
00:24:32,039 --> 00:24:37,260
input of guest preferences as statements

611
00:24:34,260 --> 00:24:39,000
which include requests such as guests

612
00:24:37,260 --> 00:24:40,919
wanting to sit next to or not next to

613
00:24:39,000 --> 00:24:44,039
another guest or wanting to sit at a

614
00:24:40,919 --> 00:24:46,020
particular seat or um anywhere so I'll

615
00:24:44,039 --> 00:24:48,720
quickly just um show you the program

616
00:24:46,020 --> 00:24:50,880
here

617
00:24:48,720 --> 00:24:53,280
um okay let me just this might be a bit

618
00:24:50,880 --> 00:24:55,860
laggy I'm not sure okay so this is the

619
00:24:53,280 --> 00:24:58,919
program itself I use the takinta GUI as

620
00:24:55,860 --> 00:25:00,539
I wasn't aware of like any other GUI

621
00:24:58,919 --> 00:25:02,460
capabilities and I think in hindsight

622
00:25:00,539 --> 00:25:04,140
perhaps using like flask or Django would

623
00:25:02,460 --> 00:25:06,659
have been more suitable as I'll show you

624
00:25:04,140 --> 00:25:08,580
that the like table visualization is

625
00:25:06,659 --> 00:25:10,980
pretty iffy so let's say that I want to

626
00:25:08,580 --> 00:25:12,780
do like a circle shape and I click um do

627
00:25:10,980 --> 00:25:14,880
five for example it's just going to run

628
00:25:12,780 --> 00:25:16,200
the same as the square shape because I

629
00:25:14,880 --> 00:25:17,640
decided to use like a ASCII

630
00:25:16,200 --> 00:25:19,620
multiplication because I couldn't figure

631
00:25:17,640 --> 00:25:23,580
out how to get to kinta to do it itself

632
00:25:19,620 --> 00:25:24,960
which was um so I used the dot grid uh I

633
00:25:23,580 --> 00:25:26,940
don't know functionality to do this

634
00:25:24,960 --> 00:25:28,919
which was originally going to be perfect

635
00:25:26,940 --> 00:25:31,260
in my head but obviously it doesn't

636
00:25:28,919 --> 00:25:32,460
always end up that way

637
00:25:31,260 --> 00:25:33,720
um yeah so then the main functionality

638
00:25:32,460 --> 00:25:35,520
you've obviously got this drop down menu

639
00:25:33,720 --> 00:25:38,520
with the different shapes so let's just

640
00:25:35,520 --> 00:25:39,720
do a rectangle let's do like a like a I

641
00:25:38,520 --> 00:25:42,659
don't know if we do like a bigger number

642
00:25:39,720 --> 00:25:44,880
I'll just show you really quickly

643
00:25:42,659 --> 00:25:46,980
um it kind of gets a bit buggy um I

644
00:25:44,880 --> 00:25:49,740
think is which as expected so here's

645
00:25:46,980 --> 00:25:51,419
text entry for the users let's say that

646
00:25:49,740 --> 00:25:53,480
I want to set

647
00:25:51,419 --> 00:25:53,480
um

648
00:25:53,940 --> 00:25:58,440
wants to oh sorry

649
00:25:56,940 --> 00:25:59,820
sit

650
00:25:58,440 --> 00:26:02,039
um let's just say I want to sit outside

651
00:25:59,820 --> 00:26:04,260
the range really quick say I want to sit

652
00:26:02,039 --> 00:26:06,600
at 13 so it's got automatic like

653
00:26:04,260 --> 00:26:08,520
updating of how many guests just for

654
00:26:06,600 --> 00:26:10,080
ease of use and then if I submit this

655
00:26:08,520 --> 00:26:11,880
it's going to give me an error message

656
00:26:10,080 --> 00:26:14,940
saying I'm sitting outside the range and

657
00:26:11,880 --> 00:26:16,500
these numbers here correspond to the

658
00:26:14,940 --> 00:26:19,440
numbers at the table up there and that's

659
00:26:16,500 --> 00:26:21,299
just the basic functionality of the

660
00:26:19,440 --> 00:26:22,980
program itself and then this is just

661
00:26:21,299 --> 00:26:25,320
props up a help button and I think

662
00:26:22,980 --> 00:26:28,320
that's the end of my demo

663
00:26:25,320 --> 00:26:29,760
um okay so yeah so how was it made

664
00:26:28,320 --> 00:26:31,500
there's three main elements to the

665
00:26:29,760 --> 00:26:33,360
program first off the visual interface

666
00:26:31,500 --> 00:26:35,640
second of all text analysis and third of

667
00:26:33,360 --> 00:26:37,740
all the algorithm itself so I first like

668
00:26:35,640 --> 00:26:39,539
made the algorithm just using text-based

669
00:26:37,740 --> 00:26:41,159
input and then I create the visual

670
00:26:39,539 --> 00:26:43,740
interface and then I integrated them

671
00:26:41,159 --> 00:26:46,140
together by modularizing the

672
00:26:43,740 --> 00:26:48,360
um all the whole thing yeah

673
00:26:46,140 --> 00:26:50,580
and so then just to further like

674
00:26:48,360 --> 00:26:51,960
breakdown of that so I used Python's

675
00:26:50,580 --> 00:26:54,600
object-oriented capabilities

676
00:26:51,960 --> 00:26:56,279
specifically so here on in the top

677
00:26:54,600 --> 00:26:58,020
picture you can see my class attendant

678
00:26:56,279 --> 00:26:59,940
which every guest was created in this

679
00:26:58,020 --> 00:27:02,039
which allowed me to store the attributes

680
00:26:59,940 --> 00:27:03,840
of their name their relation being like

681
00:27:02,039 --> 00:27:05,940
if they're fixed and next to or anywhere

682
00:27:03,840 --> 00:27:07,320
I guess and I used a numerical code for

683
00:27:05,940 --> 00:27:09,120
this instead of

684
00:27:07,320 --> 00:27:11,100
um like a string code because then I was

685
00:27:09,120 --> 00:27:12,779
able to later sort it into lists to then

686
00:27:11,100 --> 00:27:14,760
allow me to do my sequential algorithm

687
00:27:12,779 --> 00:27:15,840
which I'll expand on later

688
00:27:14,760 --> 00:27:17,580
um obviously like personally if they

689
00:27:15,840 --> 00:27:19,080
want to sit which is like where either

690
00:27:17,580 --> 00:27:21,419
the seat number that they want to sit at

691
00:27:19,080 --> 00:27:22,919
or like who they want to or don't want

692
00:27:21,419 --> 00:27:24,659
to sit next to and then negation is so

693
00:27:22,919 --> 00:27:26,460
that it'll it can differentiate between

694
00:27:24,659 --> 00:27:28,380
wanting to sit next to or like not

695
00:27:26,460 --> 00:27:29,880
wanting to sit next to people

696
00:27:28,380 --> 00:27:31,380
um and then the table class which I only

697
00:27:29,880 --> 00:27:33,000
used once because mine only deals with

698
00:27:31,380 --> 00:27:35,159
one table but for future I would like to

699
00:27:33,000 --> 00:27:37,020
expand it to have multiple tables to

700
00:27:35,159 --> 00:27:39,360
allow for like more proper event

701
00:27:37,020 --> 00:27:40,740
planning capabilities such as I don't

702
00:27:39,360 --> 00:27:43,320
know like a formal or like a wedding

703
00:27:40,740 --> 00:27:46,740
where you do have more than one um this

704
00:27:43,320 --> 00:27:49,200
bottom code here is the kind of live

705
00:27:46,740 --> 00:27:50,880
updating that I showed you earlier

706
00:27:49,200 --> 00:27:52,440
um yeah so like lots of modularization

707
00:27:50,880 --> 00:27:55,799
between it because it is like an event

708
00:27:52,440 --> 00:27:58,020
driven process overall

709
00:27:55,799 --> 00:28:00,299
um so yeah then this is like further on

710
00:27:58,020 --> 00:28:01,799
that the text analysis I mentioned

711
00:28:00,299 --> 00:28:03,240
um so it's a lot of like string

712
00:28:01,799 --> 00:28:06,960
manipulation using like replace

713
00:28:03,240 --> 00:28:09,600
functions um and testing stuff like that

714
00:28:06,960 --> 00:28:12,659
and then it um relates to my further

715
00:28:09,600 --> 00:28:14,400
classes and saves them all as inner fat

716
00:28:12,659 --> 00:28:15,900
fist I think

717
00:28:14,400 --> 00:28:18,600
um yeah so then what is this algorithm

718
00:28:15,900 --> 00:28:20,340
I've talked about so the algorithm has

719
00:28:18,600 --> 00:28:21,960
four main steps so first of all it's to

720
00:28:20,340 --> 00:28:22,980
seat the fixed people and these fixed

721
00:28:21,960 --> 00:28:24,900
people

722
00:28:22,980 --> 00:28:27,480
um are those users who have requested it

723
00:28:24,900 --> 00:28:28,919
a specific specific seat second of all

724
00:28:27,480 --> 00:28:30,059
it seats the positive pairs these are

725
00:28:28,919 --> 00:28:31,860
the pairs of people who want to sit

726
00:28:30,059 --> 00:28:33,480
together third of all seats the negative

727
00:28:31,860 --> 00:28:35,220
pairs those who don't want to sit next

728
00:28:33,480 --> 00:28:36,840
to a certain person and fourth of all

729
00:28:35,220 --> 00:28:38,279
seats that anywhere people these people

730
00:28:36,840 --> 00:28:39,659
don't have like a specified seat or

731
00:28:38,279 --> 00:28:40,919
relation so they can literally sit in

732
00:28:39,659 --> 00:28:42,480
any other spot so therefore we want to

733
00:28:40,919 --> 00:28:44,460
put them last because then that's where

734
00:28:42,480 --> 00:28:46,679
the free spots are and they're least

735
00:28:44,460 --> 00:28:48,240
constrained so in this example on the

736
00:28:46,679 --> 00:28:49,500
board Rebecca and Rio would be a

737
00:28:48,240 --> 00:28:51,480
negative pair because they don't want to

738
00:28:49,500 --> 00:28:54,059
sit together Emily would be a fixed

739
00:28:51,480 --> 00:28:55,500
person and Amy would be an anywhere

740
00:28:54,059 --> 00:28:57,720
person

741
00:28:55,500 --> 00:28:59,100
um yeah and then the seating pairs was

742
00:28:57,720 --> 00:29:00,600
like the most difficult part of the

743
00:28:59,100 --> 00:29:02,760
whole process because I had to check

744
00:29:00,600 --> 00:29:04,440
many conditions including if the other

745
00:29:02,760 --> 00:29:06,480
person is already seated if the person

746
00:29:04,440 --> 00:29:08,580
themselves is seated like where there is

747
00:29:06,480 --> 00:29:10,020
free space on the table and then also

748
00:29:08,580 --> 00:29:11,700
having to wrap around the boundaries of

749
00:29:10,020 --> 00:29:13,559
the table so for this example because

750
00:29:11,700 --> 00:29:14,760
it's a circle or it could be a rectangle

751
00:29:13,559 --> 00:29:16,080
square

752
00:29:14,760 --> 00:29:17,460
um one and four would be still

753
00:29:16,080 --> 00:29:18,779
considered next to each other so I had

754
00:29:17,460 --> 00:29:21,000
to make sure that the program could

755
00:29:18,779 --> 00:29:22,740
recognize this I do actually have a

756
00:29:21,000 --> 00:29:24,419
really weird table shape of a line which

757
00:29:22,740 --> 00:29:26,399
is like the only one that doesn't have

758
00:29:24,419 --> 00:29:27,840
this kind of end wrapping embedded

759
00:29:26,399 --> 00:29:30,480
Within

760
00:29:27,840 --> 00:29:32,880
um so on top of this this is kind of the

761
00:29:30,480 --> 00:29:34,320
process itself so just in that order as

762
00:29:32,880 --> 00:29:35,880
you can see at the top it's sorting the

763
00:29:34,320 --> 00:29:37,980
list based on the conditions that I

764
00:29:35,880 --> 00:29:42,000
stored in the objects

765
00:29:37,980 --> 00:29:43,559
um the other instances of the objects

766
00:29:42,000 --> 00:29:45,539
um and then this is just more on to that

767
00:29:43,559 --> 00:29:47,220
and then the seating negations function

768
00:29:45,539 --> 00:29:48,899
which I use for both seeing the positive

769
00:29:47,220 --> 00:29:49,740
and the negative pairs because it ended

770
00:29:48,899 --> 00:29:51,659
up

771
00:29:49,740 --> 00:29:53,279
um being more less the same so that's

772
00:29:51,659 --> 00:29:54,960
like making sure it's wrapping on the

773
00:29:53,279 --> 00:29:57,419
edges and then it's creating a list

774
00:29:54,960 --> 00:29:58,919
which it then um filters of like options

775
00:29:57,419 --> 00:30:00,299
and then it orders the list where

776
00:29:58,919 --> 00:30:02,640
there's the least amount of options and

777
00:30:00,299 --> 00:30:04,080
seats those people first and then like

778
00:30:02,640 --> 00:30:05,580
um should run it again I'm not sure if

779
00:30:04,080 --> 00:30:07,380
it actually does

780
00:30:05,580 --> 00:30:08,700
um and in hindsight I think this problem

781
00:30:07,380 --> 00:30:10,320
could actually be tackled quite

782
00:30:08,700 --> 00:30:13,260
elegantly using like the mathematical

783
00:30:10,320 --> 00:30:14,580
concept of permutations and combinations

784
00:30:13,260 --> 00:30:16,380
um which would allow for like multiple

785
00:30:14,580 --> 00:30:18,419
variations of the given Solution by the

786
00:30:16,380 --> 00:30:20,039
problem as this program currently runs

787
00:30:18,419 --> 00:30:21,899
on the expectation that all problems are

788
00:30:20,039 --> 00:30:23,580
like seatable all of the inputs that is

789
00:30:21,899 --> 00:30:26,220
given by the user are possible to be

790
00:30:23,580 --> 00:30:28,799
seated on like a singular table

791
00:30:26,220 --> 00:30:31,080
um yeah which I think is a limitation of

792
00:30:28,799 --> 00:30:32,700
it itself so then ultimately does this

793
00:30:31,080 --> 00:30:34,200
work I would say it doesn't work

794
00:30:32,700 --> 00:30:36,000
perfectly but it does work to some

795
00:30:34,200 --> 00:30:37,380
extent in terms of what I wanted to

796
00:30:36,000 --> 00:30:38,700
achieve

797
00:30:37,380 --> 00:30:40,080
um obviously there's been issues with

798
00:30:38,700 --> 00:30:41,340
the combination of the interface and

799
00:30:40,080 --> 00:30:44,460
algorithm with like the largest problem

800
00:30:41,340 --> 00:30:47,700
I faced and it would be good to have

801
00:30:44,460 --> 00:30:49,620
like a graphic perhaps use CSS or flask

802
00:30:47,700 --> 00:30:51,419
functionality to be clearer for users

803
00:30:49,620 --> 00:30:52,919
and more accurate

804
00:30:51,419 --> 00:30:54,480
um and then the key learning I'd say is

805
00:30:52,919 --> 00:30:56,039
the importance of significant variable

806
00:30:54,480 --> 00:30:57,539
names because I had multiple variables

807
00:30:56,039 --> 00:30:59,840
with the same name at the end as they

808
00:30:57,539 --> 00:31:02,700
were passing between multiple functions

809
00:30:59,840 --> 00:31:04,679
and modules and stuff and then it made

810
00:31:02,700 --> 00:31:06,360
it really hard for me to bug fix towards

811
00:31:04,679 --> 00:31:07,919
the end so yeah make sure your dot

812
00:31:06,360 --> 00:31:09,659
dictionary is good

813
00:31:07,919 --> 00:31:11,279
um and then for the future like future

814
00:31:09,659 --> 00:31:13,620
plans I'd want to like bug fix the

815
00:31:11,279 --> 00:31:16,200
algorithm improve the visualizations add

816
00:31:13,620 --> 00:31:17,820
multiple tables and be able to like

817
00:31:16,200 --> 00:31:19,200
reuse the program without re-running it

818
00:31:17,820 --> 00:31:20,940
because currently there's some bug in it

819
00:31:19,200 --> 00:31:22,320
that if you click back and like try and

820
00:31:20,940 --> 00:31:23,580
restart the program

821
00:31:22,320 --> 00:31:26,039
um it still has the previous

822
00:31:23,580 --> 00:31:27,419
requirements from the previous running

823
00:31:26,039 --> 00:31:30,179
and then also having more error messages

824
00:31:27,419 --> 00:31:31,799
such as it being not possible and I

825
00:31:30,179 --> 00:31:34,320
think that's all I have time for really

826
00:31:31,799 --> 00:31:35,880
quickly yeah I don't think I've got time

827
00:31:34,320 --> 00:31:37,919
to go over this

828
00:31:35,880 --> 00:31:40,380
um I basically just use Pi game to make

829
00:31:37,919 --> 00:31:42,120
a model of the physics experiment and I

830
00:31:40,380 --> 00:31:43,919
realized pie game is harder than it

831
00:31:42,120 --> 00:31:46,440
looks because of all the class instances

832
00:31:43,919 --> 00:31:47,760
I tried to do this the night before I

833
00:31:46,440 --> 00:31:49,620
submitted it at 3am it was quite

834
00:31:47,760 --> 00:31:52,320
traumatic for me anyway not sure I'm

835
00:31:49,620 --> 00:31:53,760
ever going to do PI game again but the

836
00:31:52,320 --> 00:31:55,980
main point is I had to make my own timer

837
00:31:53,760 --> 00:31:57,419
function because the timer I couldn't

838
00:31:55,980 --> 00:31:59,460
find an inbuilt one which was kind of

839
00:31:57,419 --> 00:32:01,320
tricky and then yeah I was trying to do

840
00:31:59,460 --> 00:32:03,720
like a like an event driven approach but

841
00:32:01,320 --> 00:32:06,480
it's mainly like a time-based

842
00:32:03,720 --> 00:32:08,100
um on Pi game and yeah that is the main

843
00:32:06,480 --> 00:32:09,120
thing that I learned oh also the

844
00:32:08,100 --> 00:32:10,860
importance of planning the project

845
00:32:09,120 --> 00:32:12,659
beforehand because all the issues with

846
00:32:10,860 --> 00:32:14,340
the maths and physics behind it I didn't

847
00:32:12,659 --> 00:32:16,080
have that down pat before I began which

848
00:32:14,340 --> 00:32:17,460
then obviously led to further problems

849
00:32:16,080 --> 00:32:19,679
down the line like the coding itself

850
00:32:17,460 --> 00:32:21,419
wasn't really the main issue in the at

851
00:32:19,679 --> 00:32:23,460
the end of the day so yeah thank you

852
00:32:21,419 --> 00:32:26,880
dancing man

853
00:32:23,460 --> 00:32:28,559
that was amazing

854
00:32:26,880 --> 00:32:30,539
um I think those are fantastic life

855
00:32:28,559 --> 00:32:32,419
lessons that maybe one day we all can

856
00:32:30,539 --> 00:32:36,779
also aspire to learn

857
00:32:32,419 --> 00:32:39,899
plan uh maybe I'll learn one day okay so

858
00:32:36,779 --> 00:32:42,480
next up on Deck we have Izzy Izzy is

859
00:32:39,899 --> 00:32:45,240
going to be talking I this is her title

860
00:32:42,480 --> 00:32:46,740
not mine flask and my terrible major

861
00:32:45,240 --> 00:32:48,840
project

862
00:32:46,740 --> 00:32:50,820
um anyone who is familiar with doing a

863
00:32:48,840 --> 00:32:53,760
major project for the HSC in New South

864
00:32:50,820 --> 00:32:56,520
Wales uh you may be crying right now but

865
00:32:53,760 --> 00:32:59,820
you can all feel that pain Izzy has been

866
00:32:56,520 --> 00:33:03,720
coding for 11 years her favorite emoji

867
00:32:59,820 --> 00:33:05,700
is the cowboy hat emoji and she yeah

868
00:33:03,720 --> 00:33:08,940
it's pretty cool yeah and uh she

869
00:33:05,700 --> 00:33:13,559
recently learned that you can animate 3D

870
00:33:08,940 --> 00:33:15,240
animations in CSS amazing and I'm gonna

871
00:33:13,559 --> 00:33:16,559
remind her that she could take her mask

872
00:33:15,240 --> 00:33:19,140
off if she wants otherwise it's probably

873
00:33:16,559 --> 00:33:21,200
the sound is probably okay

874
00:33:19,140 --> 00:33:21,200
um

875
00:33:21,570 --> 00:33:24,710
[Applause]

876
00:33:30,059 --> 00:33:33,059
right

877
00:33:30,960 --> 00:33:34,380
okay

878
00:33:33,059 --> 00:33:38,640
um

879
00:33:34,380 --> 00:33:41,720
um flask and my terrible project by

880
00:33:38,640 --> 00:33:41,720
Isabella Hogan

881
00:33:42,480 --> 00:33:48,419
all about me hi my name is Izzy and I'm

882
00:33:46,260 --> 00:33:50,840
in year 12 at a high school in New South

883
00:33:48,419 --> 00:33:50,840
Wales

884
00:33:52,260 --> 00:33:56,159
as a part of taking the software

885
00:33:54,120 --> 00:33:58,860
development course in year 12 many

886
00:33:56,159 --> 00:34:01,080
classes will undergo a major project a

887
00:33:58,860 --> 00:34:03,240
major project consists of making and

888
00:34:01,080 --> 00:34:05,880
documenting a large-scale six-month

889
00:34:03,240 --> 00:34:08,040
project of your choosing many students

890
00:34:05,880 --> 00:34:09,960
enter the course with little to no prior

891
00:34:08,040 --> 00:34:12,839
coding knowledge so they will take their

892
00:34:09,960 --> 00:34:16,200
Pro make their project with the language

893
00:34:12,839 --> 00:34:19,020
or in my case framework they were taught

894
00:34:16,200 --> 00:34:21,000
now my class was taught the JavaScript

895
00:34:19,020 --> 00:34:24,060
framework angular

896
00:34:21,000 --> 00:34:29,280
however one thing about me is

897
00:34:24,060 --> 00:34:35,220
oh I forgot that transition oh

898
00:34:29,280 --> 00:34:35,220
one thing about me is I hate angular

899
00:34:42,960 --> 00:34:47,820
we use it in year 11 for our project

900
00:34:44,879 --> 00:34:50,760
that year and honestly I just I hated it

901
00:34:47,820 --> 00:34:53,820
so much I did it so much that I started

902
00:34:50,760 --> 00:34:55,800
looking for any way to not use it and so

903
00:34:53,820 --> 00:34:57,480
with the help of my Tech Teacher mom

904
00:34:55,800 --> 00:34:59,220
shout out to

905
00:34:57,480 --> 00:35:02,940
mom

906
00:34:59,220 --> 00:35:06,300
um I chose flask to build on my python

907
00:35:02,940 --> 00:35:09,300
knowledge now I didn't know any flask at

908
00:35:06,300 --> 00:35:11,280
all but powered by Insane inherent need

909
00:35:09,300 --> 00:35:13,859
to overexert myself

910
00:35:11,280 --> 00:35:15,900
I decided I would learn it and then code

911
00:35:13,859 --> 00:35:16,859
my project and everything was gonna be

912
00:35:15,900 --> 00:35:18,720
great

913
00:35:16,859 --> 00:35:20,700
I was wrong

914
00:35:18,720 --> 00:35:22,940
at this point my to-do list looked like

915
00:35:20,700 --> 00:35:22,940
this

916
00:35:23,400 --> 00:35:30,180
to do one learn flask two do some

917
00:35:27,420 --> 00:35:34,400
documentation three make an amazing

918
00:35:30,180 --> 00:35:34,400
project and four be awesome

919
00:35:35,880 --> 00:35:40,980
so I set about completing step one

920
00:35:38,579 --> 00:35:43,859
this was about six months till the due

921
00:35:40,980 --> 00:35:46,320
date so I had heaps of time

922
00:35:43,859 --> 00:35:49,859
my first step was an online cs50

923
00:35:46,320 --> 00:35:53,160
tutorial cs50 is an online and in-person

924
00:35:49,859 --> 00:35:55,800
coding course that is taught at Harvard

925
00:35:53,160 --> 00:35:57,599
and Yale and anyone can sign up

926
00:35:55,800 --> 00:35:59,940
my mom had heard that there was a flask

927
00:35:57,599 --> 00:36:02,700
lesson in there and signed me up so

928
00:35:59,940 --> 00:36:05,460
after one lecture with a mini project at

929
00:36:02,700 --> 00:36:10,740
the end I counted that as step one done

930
00:36:05,460 --> 00:36:13,200
I had learned flask however this of

931
00:36:10,740 --> 00:36:15,720
course was not enough to make me able to

932
00:36:13,200 --> 00:36:19,020
complete my project but I didn't know

933
00:36:15,720 --> 00:36:20,700
that I however did know that at some

934
00:36:19,020 --> 00:36:22,980
point I would need to implement some

935
00:36:20,700 --> 00:36:24,900
form of database into the project the

936
00:36:22,980 --> 00:36:27,060
problem I hadn't even thought about

937
00:36:24,900 --> 00:36:29,540
databases since year 10 when I made one

938
00:36:27,060 --> 00:36:29,540
in Access

939
00:36:29,880 --> 00:36:33,660
but I filed that under problems of

940
00:36:32,040 --> 00:36:35,460
future Izzy

941
00:36:33,660 --> 00:36:38,880
and started procrastinating my next

942
00:36:35,460 --> 00:36:38,880
problem documentation

943
00:36:39,599 --> 00:36:44,040
my first documentation assessment as

944
00:36:41,700 --> 00:36:46,440
part of the class was a proposal for my

945
00:36:44,040 --> 00:36:48,180
project and in my proposal I needed to

946
00:36:46,440 --> 00:36:49,920
answer the questions

947
00:36:48,180 --> 00:36:52,440
what will it do

948
00:36:49,920 --> 00:36:55,079
who is my audience or client

949
00:36:52,440 --> 00:36:57,200
how do I think it will work and a couple

950
00:36:55,079 --> 00:37:00,380
extras

951
00:36:57,200 --> 00:37:00,380
my project

952
00:37:01,440 --> 00:37:04,800
it's a very long transitions

953
00:37:04,079 --> 00:37:07,440
um

954
00:37:04,800 --> 00:37:10,920
before I go into my project I had to

955
00:37:07,440 --> 00:37:12,960
make a PowerPoint for my proposal and I

956
00:37:10,920 --> 00:37:15,780
spent too much time on it

957
00:37:12,960 --> 00:37:19,020
considering I didn't actually need it

958
00:37:15,780 --> 00:37:20,460
that much so I have a couple slides for

959
00:37:19,020 --> 00:37:21,599
my proposal just because it took too

960
00:37:20,460 --> 00:37:24,140
long

961
00:37:21,599 --> 00:37:24,140
okay

962
00:37:24,490 --> 00:37:29,010
[Music]

963
00:37:29,280 --> 00:37:32,960
that was my logo by the way

964
00:37:34,210 --> 00:37:37,619
[Music]

965
00:37:36,240 --> 00:37:41,420
caffeine

966
00:37:37,619 --> 00:37:41,420
helping you make coffee runs easier

967
00:37:43,320 --> 00:37:47,339
the idea

968
00:37:44,700 --> 00:37:49,619
basically my idea was Center centered

969
00:37:47,339 --> 00:37:51,619
around how difficult it can be to go to

970
00:37:49,619 --> 00:37:54,000
a cafe and order for a group of people

971
00:37:51,619 --> 00:37:56,579
remembering that orders remembering how

972
00:37:54,000 --> 00:37:59,280
much are owed and so on so I created

973
00:37:56,579 --> 00:38:00,780
caffeine to help me with that the reason

974
00:37:59,280 --> 00:38:03,599
I came up with his eyes dear was

975
00:38:00,780 --> 00:38:05,280
actually my parrots every week we go

976
00:38:03,599 --> 00:38:07,320
rock climbing with some family and

977
00:38:05,280 --> 00:38:09,119
friends and at the end we all like to

978
00:38:07,320 --> 00:38:10,920
get coffee or breakfast together

979
00:38:09,119 --> 00:38:12,780
so one person will collect everyone's

980
00:38:10,920 --> 00:38:13,680
orders and then place the orders

981
00:38:12,780 --> 00:38:15,300
together

982
00:38:13,680 --> 00:38:16,980
I always saw the struggle that happened

983
00:38:15,300 --> 00:38:18,720
when trying to collect the orders and

984
00:38:16,980 --> 00:38:21,900
then remembering them while you waited

985
00:38:18,720 --> 00:38:24,119
in line so I decided I could fix it

986
00:38:21,900 --> 00:38:26,940
my main audience was any group of

987
00:38:24,119 --> 00:38:30,859
friends or colleagues that frequently

988
00:38:26,940 --> 00:38:30,859
group ordered coffee at a cafe

989
00:38:31,500 --> 00:38:36,260
sorry the speaker notes have scrolled

990
00:38:33,900 --> 00:38:36,260
too fast

991
00:38:37,200 --> 00:38:41,520
um

992
00:38:37,800 --> 00:38:43,859
oh now I have to get back up

993
00:38:41,520 --> 00:38:46,140
and I plan for it to work similarly to

994
00:38:43,859 --> 00:38:48,240
Google Classroom now for anyone who

995
00:38:46,140 --> 00:38:49,800
hasn't used Google classroom before the

996
00:38:48,240 --> 00:38:51,960
main idea was that there would be one

997
00:38:49,800 --> 00:38:54,839
person who went out to buy coffees or

998
00:38:51,960 --> 00:38:56,940
the runner and when they were about to

999
00:38:54,839 --> 00:38:59,339
leave they would then create a coffee

1000
00:38:56,940 --> 00:39:01,800
run and the app would give them a random

1001
00:38:59,339 --> 00:39:03,900
code now this code would act like a

1002
00:39:01,800 --> 00:39:05,880
password for this coffee run where

1003
00:39:03,900 --> 00:39:08,099
anyone with the code can join and place

1004
00:39:05,880 --> 00:39:09,660
their order and once the runner had

1005
00:39:08,099 --> 00:39:12,060
ordered and delivered all the coffees

1006
00:39:09,660 --> 00:39:14,040
they could simply just press done on the

1007
00:39:12,060 --> 00:39:16,500
run and all of the data about who owes

1008
00:39:14,040 --> 00:39:18,660
what would be sent to the database

1009
00:39:16,500 --> 00:39:21,540
now because I was using flask for my

1010
00:39:18,660 --> 00:39:23,940
project this concept could actually work

1011
00:39:21,540 --> 00:39:26,339
on a large scale with all the data being

1012
00:39:23,940 --> 00:39:28,500
stored on the cloud whereas the rest of

1013
00:39:26,339 --> 00:39:31,140
my class was using angular so they had

1014
00:39:28,500 --> 00:39:33,900
to store everything locally not allowing

1015
00:39:31,140 --> 00:39:36,300
for any network data this was the bit I

1016
00:39:33,900 --> 00:39:38,040
was most proud of because in the end it

1017
00:39:36,300 --> 00:39:40,280
felt like I had actually made a real

1018
00:39:38,040 --> 00:39:40,280
thing

1019
00:39:42,020 --> 00:39:47,400
but what is flask I've talked about my

1020
00:39:45,240 --> 00:39:49,200
project why I chose flask and the setup

1021
00:39:47,400 --> 00:39:51,240
of the software development as a class

1022
00:39:49,200 --> 00:39:52,440
but not really the reason for my talk

1023
00:39:51,240 --> 00:39:55,320
flask

1024
00:39:52,440 --> 00:39:58,680
flask is a python module that makes use

1025
00:39:55,320 --> 00:40:00,839
of python to connect HTML Pages the

1026
00:39:58,680 --> 00:40:03,560
pages are made just like any other HTML

1027
00:40:00,839 --> 00:40:05,640
page but then in the main Python program

1028
00:40:03,560 --> 00:40:08,700
functions are made to connect the pages

1029
00:40:05,640 --> 00:40:10,619
together and with the database this is

1030
00:40:08,700 --> 00:40:13,400
done with routing

1031
00:40:10,619 --> 00:40:15,900
where

1032
00:40:13,400 --> 00:40:18,720
the user is directed to different pages

1033
00:40:15,900 --> 00:40:21,420
with different information packets

1034
00:40:18,720 --> 00:40:23,700
so when the web page redirects a user to

1035
00:40:21,420 --> 00:40:26,040
another page like from the home page to

1036
00:40:23,700 --> 00:40:28,020
the Run page the app will also send

1037
00:40:26,040 --> 00:40:30,599
information that will be displayed on

1038
00:40:28,020 --> 00:40:33,180
this page this is how the page can show

1039
00:40:30,599 --> 00:40:36,240
customized or specific information from

1040
00:40:33,180 --> 00:40:38,760
the database and take input from the

1041
00:40:36,240 --> 00:40:40,680
user back to the database

1042
00:40:38,760 --> 00:40:43,940
now you can see why I needed specific

1043
00:40:40,680 --> 00:40:43,940
database knowledge

1044
00:40:52,859 --> 00:40:57,420
okay

1045
00:40:54,320 --> 00:40:59,099
one month from the due date I started

1046
00:40:57,420 --> 00:41:02,520
writing the pages and their flask

1047
00:40:59,099 --> 00:41:05,760
functions making use of sqlite to create

1048
00:41:02,520 --> 00:41:08,700
add to and search the database keeping

1049
00:41:05,760 --> 00:41:11,099
in mind I didn't know any sqlite before

1050
00:41:08,700 --> 00:41:13,320
this month so with the use of Google

1051
00:41:11,099 --> 00:41:16,020
online tutorials and database

1052
00:41:13,320 --> 00:41:18,240
visualizers I worked my way up to large

1053
00:41:16,020 --> 00:41:20,760
database queries that minimized any

1054
00:41:18,240 --> 00:41:22,680
effort to change the data on my part

1055
00:41:20,760 --> 00:41:24,960
so I wrote the code and it was fully

1056
00:41:22,680 --> 00:41:27,599
completed but time to spare but of

1057
00:41:24,960 --> 00:41:29,520
course something had to go wrong I go to

1058
00:41:27,599 --> 00:41:32,220
class to show my teacher and while yes

1059
00:41:29,520 --> 00:41:33,839
it does work it doesn't complete its

1060
00:41:32,220 --> 00:41:37,140
actual goal as a school assignment

1061
00:41:33,839 --> 00:41:39,599
School assignments really need to just

1062
00:41:37,140 --> 00:41:42,359
show the students knowledge rather than

1063
00:41:39,599 --> 00:41:44,160
be a full completed project

1064
00:41:42,359 --> 00:41:45,599
this was

1065
00:41:44,160 --> 00:41:48,420
the 8th of May

1066
00:41:45,599 --> 00:41:51,060
14 days before the due date of course

1067
00:41:48,420 --> 00:41:54,000
never one to do things in halves I

1068
00:41:51,060 --> 00:41:58,640
decided that this criticism meant that I

1069
00:41:54,000 --> 00:41:58,640
needed to completely restart

1070
00:42:00,839 --> 00:42:05,400
so with two weeks till the due date I

1071
00:42:03,060 --> 00:42:08,280
copied all my code into a text file and

1072
00:42:05,400 --> 00:42:10,380
started again this of course meant that

1073
00:42:08,280 --> 00:42:12,300
by the time the 12 days were up or 14

1074
00:42:10,380 --> 00:42:15,480
days were up

1075
00:42:12,300 --> 00:42:20,720
my code was not done and it didn't work

1076
00:42:15,480 --> 00:42:20,720
after all that work it didn't work

1077
00:42:20,820 --> 00:42:23,579
um

1078
00:42:22,440 --> 00:42:25,640
yeah

1079
00:42:23,579 --> 00:42:28,619
and so

1080
00:42:25,640 --> 00:42:30,720
thus ends the tale of me biting off more

1081
00:42:28,619 --> 00:42:33,240
than I could chew trying to learn too

1082
00:42:30,720 --> 00:42:35,820
much and now I would like to show a

1083
00:42:33,240 --> 00:42:40,260
demonstration if I have time

1084
00:42:35,820 --> 00:42:42,480
of the new and improved fixed project

1085
00:42:40,260 --> 00:42:44,460
Nikki

1086
00:42:42,480 --> 00:42:46,820
got time

1087
00:42:44,460 --> 00:42:46,820
okay

1088
00:42:49,020 --> 00:42:51,560
no

1089
00:42:54,359 --> 00:42:57,680
I'm getting there

1090
00:43:03,060 --> 00:43:07,319
okay

1091
00:43:04,560 --> 00:43:09,900
that's the login screen I also didn't

1092
00:43:07,319 --> 00:43:11,819
know about flask login so I made like

1093
00:43:09,900 --> 00:43:14,160
all of the login functions from scratch

1094
00:43:11,819 --> 00:43:14,760
so

1095
00:43:14,160 --> 00:43:18,200
um

1096
00:43:14,760 --> 00:43:18,200
it works sort of

1097
00:43:20,040 --> 00:43:23,420
oh didn't die

1098
00:43:30,599 --> 00:43:35,880
the Wi-Fi has been really spotty today

1099
00:43:32,520 --> 00:43:37,140
but if it loads this will log in and

1100
00:43:35,880 --> 00:43:39,660
then I will be able to direct you

1101
00:43:37,140 --> 00:43:42,000
through the rest of the app

1102
00:43:39,660 --> 00:43:44,180
otherwise I'm just going to go into the

1103
00:43:42,000 --> 00:43:44,180
code

1104
00:43:48,270 --> 00:43:53,900
[Music]

1105
00:43:50,280 --> 00:43:53,900
so they are Wi-Fi Gods today

1106
00:43:58,619 --> 00:44:04,819
no next okay you can ask Izzy for a demo

1107
00:44:01,680 --> 00:44:07,920
afterwards but continue yeah so

1108
00:44:04,819 --> 00:44:09,000
this is all of the code

1109
00:44:07,920 --> 00:44:12,420
um

1110
00:44:09,000 --> 00:44:14,880
so we did actually go through a flask

1111
00:44:12,420 --> 00:44:16,800
talk earlier that explained pretty much

1112
00:44:14,880 --> 00:44:18,900
all of this

1113
00:44:16,800 --> 00:44:21,240
um but this is the

1114
00:44:18,900 --> 00:44:24,980
the whole thing hang on

1115
00:44:21,240 --> 00:44:24,980
all of those all of those lines

1116
00:44:25,079 --> 00:44:29,099
two weeks remember

1117
00:44:27,180 --> 00:44:30,060
two

1118
00:44:29,099 --> 00:44:32,760
um

1119
00:44:30,060 --> 00:44:34,500
they're 515 lines but actually the best

1120
00:44:32,760 --> 00:44:36,660
bit is the history and I know that we're

1121
00:44:34,500 --> 00:44:37,800
not going to have enough Wi-Fi for it

1122
00:44:36,660 --> 00:44:39,720
but

1123
00:44:37,800 --> 00:44:41,080
if it loads you'll see just how many

1124
00:44:39,720 --> 00:44:42,590
versions there were

1125
00:44:41,080 --> 00:44:48,989
[Music]

1126
00:44:42,590 --> 00:44:48,989
[Applause]

1127
00:44:52,859 --> 00:44:58,020
I think we should

1128
00:44:55,280 --> 00:45:00,720
scream scream that is the right okay are

1129
00:44:58,020 --> 00:45:02,460
we good you're over time yeah I know um

1130
00:45:00,720 --> 00:45:04,500
I did actually have to go through every

1131
00:45:02,460 --> 00:45:07,740
single version just find out when I did

1132
00:45:04,500 --> 00:45:09,119
what because I didn't document but oh I

1133
00:45:07,740 --> 00:45:11,099
shouldn't have disconnected no that's

1134
00:45:09,119 --> 00:45:13,400
okay that's okay um

1135
00:45:11,099 --> 00:45:15,480
foreign

1136
00:45:13,400 --> 00:45:18,480
I'm not sure we should be encouraging

1137
00:45:15,480 --> 00:45:20,160
that many revisions but that was amazing

1138
00:45:18,480 --> 00:45:23,280
um next up we have someone who is not

1139
00:45:20,160 --> 00:45:25,200
here we've got two talks that are remote

1140
00:45:23,280 --> 00:45:27,060
presentations

1141
00:45:25,200 --> 00:45:29,520
um first up is Luke who will be talking

1142
00:45:27,060 --> 00:45:32,460
about recording about is that the verb

1143
00:45:29,520 --> 00:45:34,500
pie Graphica a simple GUI library for

1144
00:45:32,460 --> 00:45:37,260
python Luke has been programming for

1145
00:45:34,500 --> 00:45:38,640
eight years he started in year four and

1146
00:45:37,260 --> 00:45:42,140
he recently learned that in order to

1147
00:45:38,640 --> 00:45:42,140
make class attributes invisible

1148
00:45:42,660 --> 00:45:46,440
from the abyss um invisible from the

1149
00:45:45,060 --> 00:45:48,480
other side of a module you just add two

1150
00:45:46,440 --> 00:45:52,760
under

1151
00:45:48,480 --> 00:45:52,760
okay are we ready let's go

1152
00:45:54,060 --> 00:45:58,560
hello Piper my name is Luke Campbell I'm

1153
00:45:57,060 --> 00:46:00,720
a year 12 student at Saint Andrews

1154
00:45:58,560 --> 00:46:02,339
Cathedral School in Sydney and I'd like

1155
00:46:00,720 --> 00:46:05,220
to share a little bit with my Pro about

1156
00:46:02,339 --> 00:46:08,880
with you about my project pie Graphica

1157
00:46:05,220 --> 00:46:11,520
so pyrographica is a GUI and app

1158
00:46:08,880 --> 00:46:14,400
development Library designed for python

1159
00:46:11,520 --> 00:46:16,200
it's designed to be very accessible to

1160
00:46:14,400 --> 00:46:18,900
all levels of experience particularly

1161
00:46:16,200 --> 00:46:20,280
with beginners in mind because I

1162
00:46:18,900 --> 00:46:22,680
personally when I was learning

1163
00:46:20,280 --> 00:46:23,819
programming uh app development is one of

1164
00:46:22,680 --> 00:46:26,339
the things that I really wanted to learn

1165
00:46:23,819 --> 00:46:28,940
but I struggled with the learning curve

1166
00:46:26,339 --> 00:46:31,800
of some of the existing libraries so

1167
00:46:28,940 --> 00:46:33,780
playgraphica is a library that I

1168
00:46:31,800 --> 00:46:36,960
developed to help fix that and that is

1169
00:46:33,780 --> 00:46:40,099
extremely beginner friendly and

1170
00:46:36,960 --> 00:46:42,060
accessible to all levels of experience

1171
00:46:40,099 --> 00:46:42,720
so

1172
00:46:42,060 --> 00:46:44,339
um

1173
00:46:42,720 --> 00:46:46,560
the first thing I did when I was

1174
00:46:44,339 --> 00:46:49,319
building this library was I started

1175
00:46:46,560 --> 00:46:53,880
experimenting with some low-level

1176
00:46:49,319 --> 00:46:55,859
um GUI libraries like opengl and STL

1177
00:46:53,880 --> 00:46:58,800
um as opposed to higher level libraries

1178
00:46:55,859 --> 00:47:00,780
like Pi game giving into kinta I wanted

1179
00:46:58,800 --> 00:47:02,460
to start with a low-level language that

1180
00:47:00,780 --> 00:47:06,180
I could build up on

1181
00:47:02,460 --> 00:47:09,780
um so both of those opengl and sdl are

1182
00:47:06,180 --> 00:47:11,460
designed for C languages but there are

1183
00:47:09,780 --> 00:47:13,040
python wrappers that allowed me to use

1184
00:47:11,460 --> 00:47:15,420
them in Python

1185
00:47:13,040 --> 00:47:18,480
after a little bit of experimentation

1186
00:47:15,420 --> 00:47:23,400
with both I decided to go with sdl too

1187
00:47:18,480 --> 00:47:27,119
or using the pi sdl to Like Rappers

1188
00:47:23,400 --> 00:47:29,640
um so after I'd chosen the low level low

1189
00:47:27,119 --> 00:47:32,280
level language that I was going to use I

1190
00:47:29,640 --> 00:47:35,280
could start to build the classes for my

1191
00:47:32,280 --> 00:47:38,760
app so it was going to be built using

1192
00:47:35,280 --> 00:47:40,079
kind of an object oriented method

1193
00:47:38,760 --> 00:47:42,540
um

1194
00:47:40,079 --> 00:47:44,640
so I started building one class at a

1195
00:47:42,540 --> 00:47:46,740
time so first I built the window class

1196
00:47:44,640 --> 00:47:48,960
the class that the user would use to

1197
00:47:46,740 --> 00:47:51,240
create their window then I started

1198
00:47:48,960 --> 00:47:53,160
simple with lines and rectangles and I

1199
00:47:51,240 --> 00:47:55,440
built my way all the way out to the

1200
00:47:53,160 --> 00:47:58,200
really complex things like text boxes so

1201
00:47:55,440 --> 00:48:00,300
just kind of as a brief explanation the

1202
00:47:58,200 --> 00:48:02,940
more complex things like text boxes text

1203
00:48:00,300 --> 00:48:04,200
boxes for example required you know it

1204
00:48:02,940 --> 00:48:07,200
drew the rectangle that was the

1205
00:48:04,200 --> 00:48:09,420
background it drew the text onto the

1206
00:48:07,200 --> 00:48:11,700
rectangle it got the kind of keyboard

1207
00:48:09,420 --> 00:48:14,400
details for the mouse you see it saw

1208
00:48:11,700 --> 00:48:16,140
kind of whether where the mouse was

1209
00:48:14,400 --> 00:48:19,319
whether it be clipped so whether it was

1210
00:48:16,140 --> 00:48:21,480
kind of clicked into or clicked out of

1211
00:48:19,319 --> 00:48:24,000
um it saw what key changes had occurred

1212
00:48:21,480 --> 00:48:25,440
So what had been typed there there's

1213
00:48:24,000 --> 00:48:27,420
nothing had been typed there whether it

1214
00:48:25,440 --> 00:48:30,480
needed to display any placeholder text

1215
00:48:27,420 --> 00:48:33,180
and there are a lot of details

1216
00:48:30,480 --> 00:48:35,880
um to kind of all juggle at once which

1217
00:48:33,180 --> 00:48:38,520
is a pain to program every time you want

1218
00:48:35,880 --> 00:48:40,980
a text box but um

1219
00:48:38,520 --> 00:48:42,660
my library kind of presents it in just

1220
00:48:40,980 --> 00:48:44,880
one single line of code you can create a

1221
00:48:42,660 --> 00:48:46,619
text box

1222
00:48:44,880 --> 00:48:48,300
um so once I'd kind of made all the

1223
00:48:46,619 --> 00:48:51,420
classes individually I had to make them

1224
00:48:48,300 --> 00:48:53,280
kind of cross-compatible so all or for

1225
00:48:51,420 --> 00:48:56,640
example all the flight classes use the

1226
00:48:53,280 --> 00:49:01,740
same attribute names for their start

1227
00:48:56,640 --> 00:49:04,800
name coordinates X1 y1 and X2 Y2 and

1228
00:49:01,740 --> 00:49:06,599
that means that you can use a certain

1229
00:49:04,800 --> 00:49:07,920
piece of code on

1230
00:49:06,599 --> 00:49:10,319
any

1231
00:49:07,920 --> 00:49:12,240
any object in that let like let's say

1232
00:49:10,319 --> 00:49:14,040
you want to make yourself function to

1233
00:49:12,240 --> 00:49:16,859
see whether something's been collided

1234
00:49:14,040 --> 00:49:18,720
with then you can put any object into

1235
00:49:16,859 --> 00:49:21,780
that you can put a text object or a text

1236
00:49:18,720 --> 00:49:24,300
box or a rectangle or a line or anything

1237
00:49:21,780 --> 00:49:26,160
and it will go and it you can use the

1238
00:49:24,300 --> 00:49:28,440
same attributes for it

1239
00:49:26,160 --> 00:49:30,180
so once the kind of programming side was

1240
00:49:28,440 --> 00:49:32,819
done I needed to package it to put it on

1241
00:49:30,180 --> 00:49:35,819
Pipeline so this involved kind of all

1242
00:49:32,819 --> 00:49:37,980
the installation details

1243
00:49:35,819 --> 00:49:40,859
um or like the dependencies

1244
00:49:37,980 --> 00:49:45,180
and then various other things like um

1245
00:49:40,859 --> 00:49:47,520
like the like various detail sheets

1246
00:49:45,180 --> 00:49:49,740
um that all needed to be packaged to

1247
00:49:47,520 --> 00:49:52,140
then go put it on pipei

1248
00:49:49,740 --> 00:49:54,660
um then the next stage was create user

1249
00:49:52,140 --> 00:49:56,099
documentation because obviously this was

1250
00:49:54,660 --> 00:49:58,800
not just code for me I wanted everybody

1251
00:49:56,099 --> 00:50:01,200
to be able to use this code so I wrote

1252
00:49:58,800 --> 00:50:04,440
kind of kind of an instruction manual

1253
00:50:01,200 --> 00:50:06,619
for all of the functions and classes in

1254
00:50:04,440 --> 00:50:09,060
there so that anybody could learn that

1255
00:50:06,619 --> 00:50:10,079
and then lastly I release the code on

1256
00:50:09,060 --> 00:50:12,000
GitHub

1257
00:50:10,079 --> 00:50:14,760
um it's all fully commented it's open

1258
00:50:12,000 --> 00:50:15,540
source check it out if you want

1259
00:50:14,760 --> 00:50:19,020
um

1260
00:50:15,540 --> 00:50:20,339
yeah it's on GitHub so check it out

1261
00:50:19,020 --> 00:50:23,579
um I really love doing this product

1262
00:50:20,339 --> 00:50:25,560
project because I learned a lot about

1263
00:50:23,579 --> 00:50:27,420
very a lot of different things so I

1264
00:50:25,560 --> 00:50:30,180
learned a lot about object I'm oriented

1265
00:50:27,420 --> 00:50:32,700
programming I'd use classes and objects

1266
00:50:30,180 --> 00:50:35,339
before but uh through this I learned so

1267
00:50:32,700 --> 00:50:39,300
much more about them

1268
00:50:35,339 --> 00:50:41,940
um I also developed my ability to make

1269
00:50:39,300 --> 00:50:44,099
very user-friendly code as well because

1270
00:50:41,940 --> 00:50:46,500
a lot of code I've written has been just

1271
00:50:44,099 --> 00:50:48,359
for me for my use but now this was

1272
00:50:46,500 --> 00:50:49,859
something that I wanted anybody to be

1273
00:50:48,359 --> 00:50:51,900
able to use so it needed to be extremely

1274
00:50:49,859 --> 00:50:53,760
user friendly

1275
00:50:51,900 --> 00:50:55,619
um and then also about the various

1276
00:50:53,760 --> 00:50:57,240
packaging details and how to put it on

1277
00:50:55,619 --> 00:50:59,760
Pipeline which is a skill that I'll use

1278
00:50:57,240 --> 00:51:03,180
again in the future I'm sure

1279
00:50:59,760 --> 00:51:05,700
um so now I'll just quickly kind of show

1280
00:51:03,180 --> 00:51:07,440
you a little bit of this so it's

1281
00:51:05,700 --> 00:51:10,800
available on Piper so you can download

1282
00:51:07,440 --> 00:51:15,980
it via install but

1283
00:51:10,800 --> 00:51:15,980
if I'll just get my screen recording up

1284
00:51:21,240 --> 00:51:28,140
here we go so

1285
00:51:24,020 --> 00:51:30,119
this is a simple program that I made

1286
00:51:28,140 --> 00:51:32,160
with pie Graphica

1287
00:51:30,119 --> 00:51:34,380
as you can see there's not many lines

1288
00:51:32,160 --> 00:51:36,300
starts off with just an import these are

1289
00:51:34,380 --> 00:51:37,800
various functions draw is where most of

1290
00:51:36,300 --> 00:51:39,900
the functions are kept

1291
00:51:37,800 --> 00:51:43,200
font has a bunch of kind of default

1292
00:51:39,900 --> 00:51:45,720
fonts I think it's got 11 or 12 defaults

1293
00:51:43,200 --> 00:51:48,300
colors as much of default colors of

1294
00:51:45,720 --> 00:51:51,119
course for fonts and colors you can use

1295
00:51:48,300 --> 00:51:53,280
your own if you want but those are there

1296
00:51:51,119 --> 00:51:55,980
to make things easier and then Origins

1297
00:51:53,280 --> 00:51:58,920
you can set your origin to either the

1298
00:51:55,980 --> 00:52:01,980
top left corner top right corner bottom

1299
00:51:58,920 --> 00:52:03,119
left corner bottom right corner or the

1300
00:52:01,980 --> 00:52:05,160
center

1301
00:52:03,119 --> 00:52:06,780
and then you have one line for each

1302
00:52:05,160 --> 00:52:07,619
thing essentially one lines create the

1303
00:52:06,780 --> 00:52:10,859
window

1304
00:52:07,619 --> 00:52:13,260
one line to draw each piece of text one

1305
00:52:10,859 --> 00:52:16,859
line to draw the text box

1306
00:52:13,260 --> 00:52:18,599
um which is particularly annoying in uh

1307
00:52:16,859 --> 00:52:21,180
like drawing text boxes is particularly

1308
00:52:18,599 --> 00:52:23,520
annoying in a lot of libraries like like

1309
00:52:21,180 --> 00:52:27,240
pie game whereas this allows you to do

1310
00:52:23,520 --> 00:52:29,520
that just in one line and then one line

1311
00:52:27,240 --> 00:52:30,720
to draw the text in the button one line

1312
00:52:29,520 --> 00:52:32,700
to draw

1313
00:52:30,720 --> 00:52:36,599
the rectangle around the button this is

1314
00:52:32,700 --> 00:52:38,339
one example of the class attributes so

1315
00:52:36,599 --> 00:52:41,099
to create the rectangle around it

1316
00:52:38,339 --> 00:52:43,380
instead of kind of experimenting to see

1317
00:52:41,099 --> 00:52:45,059
where the end of the text box was

1318
00:52:43,380 --> 00:52:46,740
I simply

1319
00:52:45,059 --> 00:52:48,720
got the coordinates from the class

1320
00:52:46,740 --> 00:52:52,500
itself and then added a little bit of

1321
00:52:48,720 --> 00:52:54,059
margin so it wasn't right around it

1322
00:52:52,500 --> 00:52:56,579
and then

1323
00:52:54,059 --> 00:52:58,319
uh in this this is all more class

1324
00:52:56,579 --> 00:52:59,220
attributes whether it's being hovered

1325
00:52:58,319 --> 00:53:01,380
over

1326
00:52:59,220 --> 00:53:03,680
whether it's been clipped or not and

1327
00:53:01,380 --> 00:53:07,859
then this app.update

1328
00:53:03,680 --> 00:53:08,880
instead of updating every single

1329
00:53:07,859 --> 00:53:11,220
um

1330
00:53:08,880 --> 00:53:13,680
element individually they all get

1331
00:53:11,220 --> 00:53:15,000
updated in this one update and if you

1332
00:53:13,680 --> 00:53:16,619
don't want something to be drawn then

1333
00:53:15,000 --> 00:53:19,740
you can just set it as

1334
00:53:16,619 --> 00:53:24,119
I was doing example box dot

1335
00:53:19,740 --> 00:53:25,800
um visible equals false and then that

1336
00:53:24,119 --> 00:53:26,819
doesn't display anymore and then you can

1337
00:53:25,800 --> 00:53:28,800
turn that off

1338
00:53:26,819 --> 00:53:31,559
back to true if you want to display it

1339
00:53:28,800 --> 00:53:34,859
again so this is a very dodgy looking

1340
00:53:31,559 --> 00:53:37,440
website uh sorry app but it's just an

1341
00:53:34,859 --> 00:53:41,339
example of some of the functions that

1342
00:53:37,440 --> 00:53:43,920
pie Graphica can do so again very

1343
00:53:41,339 --> 00:53:47,940
dodgy but

1344
00:53:43,920 --> 00:53:48,720
it works so now for a slightly more

1345
00:53:47,940 --> 00:53:52,740
um

1346
00:53:48,720 --> 00:53:54,839
interesting demonstration this is an app

1347
00:53:52,740 --> 00:53:56,640
I kind of built as kind of a proof of

1348
00:53:54,839 --> 00:53:57,660
concept that

1349
00:53:56,640 --> 00:54:00,300
um

1350
00:53:57,660 --> 00:54:02,520
it did actually work

1351
00:54:00,300 --> 00:54:05,339
um the pie graphical word I built this

1352
00:54:02,520 --> 00:54:07,380
whole app with biographical this is an

1353
00:54:05,339 --> 00:54:10,500
app it's actually an app for a website

1354
00:54:07,380 --> 00:54:12,720
that I built quite a while ago now CS is

1355
00:54:10,500 --> 00:54:14,940
an online system that kind of allows you

1356
00:54:12,720 --> 00:54:17,579
to play location games like hide and

1357
00:54:14,940 --> 00:54:19,619
seek and tips over much greater areas

1358
00:54:17,579 --> 00:54:21,420
like a whole city for example I've done

1359
00:54:19,619 --> 00:54:22,079
that one it's very fun

1360
00:54:21,420 --> 00:54:25,500
um

1361
00:54:22,079 --> 00:54:27,660
so you sign on you get yourself a game

1362
00:54:25,500 --> 00:54:28,920
it generates a game code for you you can

1363
00:54:27,660 --> 00:54:30,660
send that to your friends they can log

1364
00:54:28,920 --> 00:54:33,059
on to the same game as you

1365
00:54:30,660 --> 00:54:36,240
and then it'll send kind of the location

1366
00:54:33,059 --> 00:54:38,099
of the person you're chasing to you and

1367
00:54:36,240 --> 00:54:40,079
your location will be said to the person

1368
00:54:38,099 --> 00:54:42,780
who's chasing you and therefore you can

1369
00:54:40,079 --> 00:54:44,760
chase them even if they're across the

1370
00:54:42,780 --> 00:54:47,460
other side of a city for example

1371
00:54:44,760 --> 00:54:49,800
uh but that is not the purpose of this

1372
00:54:47,460 --> 00:54:52,200
talk uh this is just an example of

1373
00:54:49,800 --> 00:54:55,319
something you can do with pie Graphica

1374
00:54:52,200 --> 00:54:56,880
this isn't complete obviously but it

1375
00:54:55,319 --> 00:54:59,160
just has some of the

1376
00:54:56,880 --> 00:55:01,440
settings

1377
00:54:59,160 --> 00:55:04,559
and is kind of a proof of concept that

1378
00:55:01,440 --> 00:55:07,040
biographica can crash

1379
00:55:04,559 --> 00:55:07,040
so

1380
00:55:07,380 --> 00:55:11,579
um in the future uh I want to take this

1381
00:55:10,079 --> 00:55:13,140
a little bit further this project is far

1382
00:55:11,579 --> 00:55:15,180
from complete it's kind of it's

1383
00:55:13,140 --> 00:55:16,500
available and it's fully functioning but

1384
00:55:15,180 --> 00:55:19,020
there are more things I want to add to

1385
00:55:16,500 --> 00:55:21,000
it I want to add more functions to kind

1386
00:55:19,020 --> 00:55:23,400
of make it more powerful there's a few

1387
00:55:21,000 --> 00:55:25,800
bits in the code I want to tidy up and

1388
00:55:23,400 --> 00:55:28,020
then obviously I want to finish off the

1389
00:55:25,800 --> 00:55:30,119
now CS app I was making and release that

1390
00:55:28,020 --> 00:55:32,280
to the App Store

1391
00:55:30,119 --> 00:55:33,900
um I hope you've enjoyed hearing about

1392
00:55:32,280 --> 00:55:36,960
biographica

1393
00:55:33,900 --> 00:55:39,900
um please it's available on pie pie so

1394
00:55:36,960 --> 00:55:42,660
just download it pip install and give it

1395
00:55:39,900 --> 00:55:44,819
a shot the user manual is on Piper as

1396
00:55:42,660 --> 00:55:47,760
well or you can check it out on GitHub

1397
00:55:44,819 --> 00:55:50,119
and yeah check it out and thank you for

1398
00:55:47,760 --> 00:55:50,119
listening

1399
00:55:58,619 --> 00:56:03,660
there we go our last speaker then sounds

1400
00:56:01,680 --> 00:56:05,640
like some of my past students who text

1401
00:56:03,660 --> 00:56:08,640
me five years after they'd left school

1402
00:56:05,640 --> 00:56:10,559
to say hi Mrs Mathers just wanted to let

1403
00:56:08,640 --> 00:56:13,099
you know that code that didn't work in

1404
00:56:10,559 --> 00:56:15,359
grade 12 I've been working at it lately

1405
00:56:13,099 --> 00:56:17,880
today I'll be demonstrating and

1406
00:56:15,359 --> 00:56:20,819
showcasing my bbr Cipher which I created

1407
00:56:17,880 --> 00:56:22,319
as a conceptual idea and by the way I'm

1408
00:56:20,819 --> 00:56:25,500
working for the military and I thought

1409
00:56:22,319 --> 00:56:27,119
to myself oh God no they haven't oh I

1410
00:56:25,500 --> 00:56:29,160
have I think they've made a mistake

1411
00:56:27,119 --> 00:56:32,339
because that was one of the naughtiest

1412
00:56:29,160 --> 00:56:35,460
students I've ever had in my life so

1413
00:56:32,339 --> 00:56:38,520
um a second only to the one that got D's

1414
00:56:35,460 --> 00:56:40,880
all the way through and I found out two

1415
00:56:38,520 --> 00:56:44,880
years later that he's a pilot

1416
00:56:40,880 --> 00:56:46,260
for Qantas so I'm one of those sorts of

1417
00:56:44,880 --> 00:56:48,000
teachers who sits there on the plane

1418
00:56:46,260 --> 00:56:50,640
until the Pilot introduces themselves

1419
00:56:48,000 --> 00:56:52,450
before they relax because I know he

1420
00:56:50,640 --> 00:56:55,560
doesn't concentrate

1421
00:56:52,450 --> 00:56:55,560
[Music]

1422
00:56:55,980 --> 00:57:01,020
so our next talker uh the speaker we've

1423
00:56:58,859 --> 00:57:03,660
got a video again and after that we've

1424
00:57:01,020 --> 00:57:07,200
got a couple of more live victims for

1425
00:57:03,660 --> 00:57:11,240
you so this next one is Mark Mann custom

1426
00:57:07,200 --> 00:57:14,460
encryptions is the topic so hacker to be

1427
00:57:11,240 --> 00:57:18,720
I've been programming he says for 10

1428
00:57:14,460 --> 00:57:21,300
years since I was seven

1429
00:57:18,720 --> 00:57:22,920
yeah sounds like an old guy right I

1430
00:57:21,300 --> 00:57:26,280
recently learned about the artificial

1431
00:57:22,920 --> 00:57:29,099
intelligence and data manipulation and

1432
00:57:26,280 --> 00:57:31,800
he puts in Brackets sockets too not sure

1433
00:57:29,099 --> 00:57:33,720
what that means that's beyond me so

1434
00:57:31,800 --> 00:57:36,780
hopefully

1435
00:57:33,720 --> 00:57:38,520
Mark can let us know

1436
00:57:36,780 --> 00:57:41,040
today I'll be demonstrating and

1437
00:57:38,520 --> 00:57:43,200
showcasing my bbr Cipher which I created

1438
00:57:41,040 --> 00:57:44,700
as a conceptual idea three years ago to

1439
00:57:43,200 --> 00:57:46,200
learn about encryption and its different

1440
00:57:44,700 --> 00:57:49,079
methods

1441
00:57:46,200 --> 00:57:50,520
so to start off a bit about me is I've

1442
00:57:49,079 --> 00:57:52,140
been programming for around 10 years

1443
00:57:50,520 --> 00:57:54,000
since I was seven

1444
00:57:52,140 --> 00:57:55,500
I've mostly used python as it was the

1445
00:57:54,000 --> 00:57:58,260
language that my dad introduced me to

1446
00:57:55,500 --> 00:58:00,240
but I've learned HTML JavaScript and a

1447
00:57:58,260 --> 00:58:02,160
little bit of lore along the way

1448
00:58:00,240 --> 00:58:03,900
as of this moment I'm currently learning

1449
00:58:02,160 --> 00:58:05,520
C plus plus in the hopes that I'll be

1450
00:58:03,900 --> 00:58:07,859
able to turn some of my python programs

1451
00:58:05,520 --> 00:58:11,400
into C plus plus programs

1452
00:58:07,859 --> 00:58:13,680
now my program uses base64 to encode the

1453
00:58:11,400 --> 00:58:16,020
data that I input twice

1454
00:58:13,680 --> 00:58:17,880
and then uses a rotation server to take

1455
00:58:16,020 --> 00:58:21,059
an order from the hash password using

1456
00:58:17,880 --> 00:58:22,920
sha 256 to rotate the ordinal of the

1457
00:58:21,059 --> 00:58:25,619
current character in the input by set

1458
00:58:22,920 --> 00:58:27,839
amount so when it rotates I then encode

1459
00:58:25,619 --> 00:58:30,780
that rotation in base 85 and combine

1460
00:58:27,839 --> 00:58:32,160
these using the code 39b gen as that is

1461
00:58:30,780 --> 00:58:34,619
something that is not likely to occur

1462
00:58:32,160 --> 00:58:38,339
all that often it then encodes the

1463
00:58:34,619 --> 00:58:41,640
base85 in base64 and outputs the result

1464
00:58:38,339 --> 00:58:43,200
next pros and cons

1465
00:58:41,640 --> 00:58:45,780
one of the pros is the output

1466
00:58:43,200 --> 00:58:47,880
readability it's not easy to read so you

1467
00:58:45,780 --> 00:58:49,740
can't easily discern that it is Data you

1468
00:58:47,880 --> 00:58:51,240
can recognize it as base64 if you know

1469
00:58:49,740 --> 00:58:53,400
what to look for

1470
00:58:51,240 --> 00:58:55,079
so while it says on the screen it uses

1471
00:58:53,400 --> 00:58:57,119
multiple encryption methods it's more

1472
00:58:55,079 --> 00:58:59,339
like an encryption and a half it's one

1473
00:58:57,119 --> 00:59:01,440
encryption and then four encodings while

1474
00:58:59,339 --> 00:59:03,420
it does increase unreadability it causes

1475
00:59:01,440 --> 00:59:05,640
excessive inflation of data

1476
00:59:03,420 --> 00:59:06,780
the next Pro is the data scrambling from

1477
00:59:05,640 --> 00:59:09,119
the encoding

1478
00:59:06,780 --> 00:59:10,740
the programming codes would be 64 twice

1479
00:59:09,119 --> 00:59:12,660
at the beginning to scramble the data

1480
00:59:10,740 --> 00:59:14,880
encrypts it and then encodes for Bay

1481
00:59:12,660 --> 00:59:15,960
City 5 and base64 to scramble it even

1482
00:59:14,880 --> 00:59:18,299
more

1483
00:59:15,960 --> 00:59:20,460
so for the first con the fine coding to

1484
00:59:18,299 --> 00:59:22,680
cause the data to inflate at around 112

1485
00:59:20,460 --> 00:59:24,180
to 1 which is not a good payoff for

1486
00:59:22,680 --> 00:59:27,359
secure data

1487
00:59:24,180 --> 00:59:29,220
then the separator 39b gem adds some

1488
00:59:27,359 --> 00:59:31,559
recursion people can recognize

1489
00:59:29,220 --> 00:59:33,180
repetition and it makes it insecure but

1490
00:59:31,559 --> 00:59:35,460
it is also inefficient

1491
00:59:33,180 --> 00:59:37,980
so now for an example this is a

1492
00:59:35,460 --> 00:59:41,040
demonstration on my program in action

1493
00:59:37,980 --> 00:59:44,160
so I can open my application

1494
00:59:41,040 --> 00:59:47,940
and it will open a window

1495
00:59:44,160 --> 00:59:50,579
and give me four options encrypt encrypt

1496
00:59:47,940 --> 00:59:52,980
file decrypt and decrypt file

1497
00:59:50,579 --> 00:59:54,299
so when I click encrypt we can put in a

1498
00:59:52,980 --> 00:59:56,099
short phrase

1499
00:59:54,299 --> 00:59:57,180
with an exclamation mark for a special

1500
00:59:56,099 --> 01:00:00,540
character

1501
00:59:57,180 --> 01:00:03,359
and then I can put in the test passcode

1502
01:00:00,540 --> 01:00:04,980
and it will give me some random data if

1503
01:00:03,359 --> 01:00:08,520
I cannot read

1504
01:00:04,980 --> 01:00:11,280
so this data is the encrypted

1505
01:00:08,520 --> 01:00:12,960
information so I can put it into decrypt

1506
01:00:11,280 --> 01:00:15,660
and paste it

1507
01:00:12,960 --> 01:00:17,880
if I were to do the wrong passcode

1508
01:00:15,660 --> 01:00:20,520
it would give me some data that I cannot

1509
01:00:17,880 --> 01:00:24,180
read just two characters because the

1510
01:00:20,520 --> 01:00:27,839
rest is not printable

1511
01:00:24,180 --> 01:00:30,720
so I can decrypt it put in the same data

1512
01:00:27,839 --> 01:00:33,059
but this time did the correct phrase

1513
01:00:30,720 --> 01:00:34,799
and it will give me the output short

1514
01:00:33,059 --> 01:00:38,760
phrase

1515
01:00:34,799 --> 01:00:42,540
so I took the liberty of creating a test

1516
01:00:38,760 --> 01:00:44,760
file with a long phrase with spiritual

1517
01:00:42,540 --> 01:00:46,260
characters and numbers new lines and all

1518
01:00:44,760 --> 01:00:48,540
the characters in the alphabet both

1519
01:00:46,260 --> 01:00:51,839
uppercase and lowercase

1520
01:00:48,540 --> 01:00:52,980
so if I already if I were to run my

1521
01:00:51,839 --> 01:00:57,059
program again

1522
01:00:52,980 --> 01:01:00,240
but this time select encrypt file

1523
01:00:57,059 --> 01:01:02,339
and then select test dot text

1524
01:01:00,240 --> 01:01:06,240
and then I can save it

1525
01:01:02,339 --> 01:01:09,299
and the extensions.bbr because that's

1526
01:01:06,240 --> 01:01:10,740
the name of my program and so that's the

1527
01:01:09,299 --> 01:01:13,220
extension I'm using

1528
01:01:10,740 --> 01:01:16,079
so it will save it to

1529
01:01:13,220 --> 01:01:17,460
encrypted.txt dot bvr so we'll use the

1530
01:01:16,079 --> 01:01:19,799
same passcode

1531
01:01:17,460 --> 01:01:21,299
and it will encrypt and as you can see

1532
01:01:19,799 --> 01:01:24,720
in the background here

1533
01:01:21,299 --> 01:01:27,900
it is showing me the output

1534
01:01:24,720 --> 01:01:32,460
so it says where it's been saved so I

1535
01:01:27,900 --> 01:01:32,460
can open in Notepad encrypted.txt.bbr

1536
01:01:32,940 --> 01:01:37,140
and it is a whole bunch of random data I

1537
01:01:35,880 --> 01:01:39,780
can't read it

1538
01:01:37,140 --> 01:01:41,520
it's got new lines in there because it's

1539
01:01:39,780 --> 01:01:43,380
rotating there's a chance it's going to

1540
01:01:41,520 --> 01:01:45,660
get new lights

1541
01:01:43,380 --> 01:01:47,119
so I can open

1542
01:01:45,660 --> 01:01:49,859
the

1543
01:01:47,119 --> 01:01:53,819
program again

1544
01:01:49,859 --> 01:01:55,200
and select decrypt file

1545
01:01:53,819 --> 01:01:58,200
and then when I select

1546
01:01:55,200 --> 01:01:58,200
encrypted.text.bbr

1547
01:01:58,799 --> 01:02:05,160
and I put in the Run code

1548
01:02:02,579 --> 01:02:07,079
it will attempt error decode failed

1549
01:02:05,160 --> 01:02:10,079
check below for our details incorrect

1550
01:02:07,079 --> 01:02:12,299
padding that's debug purposes

1551
01:02:10,079 --> 01:02:16,559
it obviously would not be safe to have

1552
01:02:12,299 --> 01:02:21,980
that if I were to give it out to people

1553
01:02:16,559 --> 01:02:23,700
so I then select decrypt file

1554
01:02:21,980 --> 01:02:25,799
encrypted.txt.bbr

1555
01:02:23,700 --> 01:02:28,440
open

1556
01:02:25,799 --> 01:02:31,980
and this time do the correct code

1557
01:02:28,440 --> 01:02:34,980
it will decode it and it says decrypted

1558
01:02:31,980 --> 01:02:37,819
as the location

1559
01:02:34,980 --> 01:02:40,260
so now I can open

1560
01:02:37,819 --> 01:02:42,240
encrypted.txt in Notepad

1561
01:02:40,260 --> 01:02:44,099
and it appears the exact same as

1562
01:02:42,240 --> 01:02:47,700
test.txt

1563
01:02:44,099 --> 01:02:50,480
to be sure I'm going to type FC for file

1564
01:02:47,700 --> 01:02:54,059
prepare slash B for binary then

1565
01:02:50,480 --> 01:02:56,280
encrypted.txt and test dot text

1566
01:02:54,059 --> 01:02:59,180
now differences encountered they are

1567
01:02:56,280 --> 01:02:59,180
indeed the exact same

1568
01:03:00,960 --> 01:03:05,280
so as I was working on this project

1569
01:03:02,819 --> 01:03:07,799
there were a series of bugs and logical

1570
01:03:05,280 --> 01:03:10,440
errors such as reading and writing files

1571
01:03:07,799 --> 01:03:12,720
as text rather than as bytes causing it

1572
01:03:10,440 --> 01:03:15,059
to occasionally complain saying invalid

1573
01:03:12,720 --> 01:03:16,500
start lines it was an easy fix by

1574
01:03:15,059 --> 01:03:17,520
changing it to reading and writing as

1575
01:03:16,500 --> 01:03:19,980
bytes

1576
01:03:17,520 --> 01:03:22,559
for The Logical errors one was having it

1577
01:03:19,980 --> 01:03:24,420
encode and decode correctly but give the

1578
01:03:22,559 --> 01:03:26,040
wrong output and the reason for that was

1579
01:03:24,420 --> 01:03:28,500
that it was using some incorrect maths

1580
01:03:26,040 --> 01:03:30,660
and getting thrown off by a small degree

1581
01:03:28,500 --> 01:03:33,240
so what I did for my logical errors was

1582
01:03:30,660 --> 01:03:34,859
I included try catch statements I catch

1583
01:03:33,240 --> 01:03:37,020
the error and I printed out and then

1584
01:03:34,859 --> 01:03:38,400
quiz when I print the error I print the

1585
01:03:37,020 --> 01:03:40,920
type of error as well as the actual

1586
01:03:38,400 --> 01:03:42,720
message and since the program's still

1587
01:03:40,920 --> 01:03:44,040
running I can also print out all

1588
01:03:42,720 --> 01:03:46,140
variables that are currently in use

1589
01:03:44,040 --> 01:03:47,819
allowing me to debug and see where the

1590
01:03:46,140 --> 01:03:50,640
program went well

1591
01:03:47,819 --> 01:03:53,700
so some of the things that went well

1592
01:03:50,640 --> 01:03:55,559
was my planning I put my plans for

1593
01:03:53,700 --> 01:03:57,900
potential algorithms onto paper using my

1594
01:03:55,559 --> 01:03:59,339
calculator for the mats once I was done

1595
01:03:57,900 --> 01:04:01,200
planning I tested on the computer by

1596
01:03:59,339 --> 01:04:02,460
creating a basic program to emulate each

1597
01:04:01,200 --> 01:04:04,380
step

1598
01:04:02,460 --> 01:04:06,000
debugging was fairly easy especially

1599
01:04:04,380 --> 01:04:07,920
with Python's comprehensive error

1600
01:04:06,000 --> 01:04:09,839
messages it tells me what happened and

1601
01:04:07,920 --> 01:04:12,420
where making it very easy for me to

1602
01:04:09,839 --> 01:04:14,579
trace and fix any bugs that popped up

1603
01:04:12,420 --> 01:04:16,740
as for my testing I implemented to try

1604
01:04:14,579 --> 01:04:18,540
cash to help me find some logical errors

1605
01:04:16,740 --> 01:04:20,760
and I'll also helped me print out

1606
01:04:18,540 --> 01:04:22,920
variables

1607
01:04:20,760 --> 01:04:24,420
now because this is three years ago I've

1608
01:04:22,920 --> 01:04:26,640
learned things since

1609
01:04:24,420 --> 01:04:28,380
so if I were to remake this program what

1610
01:04:26,640 --> 01:04:30,420
would I do to make it better

1611
01:04:28,380 --> 01:04:31,980
an example of what I might do is if I

1612
01:04:30,420 --> 01:04:34,559
can experiment with different ciphers

1613
01:04:31,980 --> 01:04:37,500
because as of this moment there is only

1614
01:04:34,559 --> 01:04:39,180
one Cipher in four encodings and it'd be

1615
01:04:37,500 --> 01:04:41,099
great to learn different disciples as

1616
01:04:39,180 --> 01:04:42,599
well as this one

1617
01:04:41,099 --> 01:04:44,520
it'd be nice if I could decrease the

1618
01:04:42,599 --> 01:04:46,140
inflation from 112 to 1 to something

1619
01:04:44,520 --> 01:04:48,359
more reasonable

1620
01:04:46,140 --> 01:04:49,559
because again another learning

1621
01:04:48,359 --> 01:04:51,480
experience

1622
01:04:49,559 --> 01:04:54,720
and I'd also reduce the repetition

1623
01:04:51,480 --> 01:04:57,359
because whilst having 39b gen is great

1624
01:04:54,720 --> 01:04:58,920
because I can split the characters it is

1625
01:04:57,359 --> 01:05:01,799
also inefficient

1626
01:04:58,920 --> 01:05:04,500
so perhaps I will remake this someday

1627
01:05:01,799 --> 01:05:06,240
in summary my program was created as a

1628
01:05:04,500 --> 01:05:07,559
collection of conceptual ideas and a

1629
01:05:06,240 --> 01:05:08,400
mixed match of other methods that I've

1630
01:05:07,559 --> 01:05:09,960
read about

1631
01:05:08,400 --> 01:05:11,520
there's still quite a lot of things I

1632
01:05:09,960 --> 01:05:13,680
can learn from this project so I might

1633
01:05:11,520 --> 01:05:16,380
come back later to redo it overall it

1634
01:05:13,680 --> 01:05:19,339
was an excellent project and lots of fun

1635
01:05:16,380 --> 01:05:19,339
thanks for listening

1636
01:06:26,240 --> 01:06:29,240
thank you

1637
01:06:36,780 --> 01:06:39,780
hey

1638
01:06:43,740 --> 01:06:45,920
okay

1639
01:06:46,020 --> 01:06:50,460
all right so we now have a Sam's side

1640
01:06:49,260 --> 01:06:52,380
bottom

1641
01:06:50,460 --> 01:06:54,900
um Morgan Potter and Joshua

1642
01:06:52,380 --> 01:06:57,240
his norbow okay

1643
01:06:54,900 --> 01:06:59,220
um and we're gonna do uh rather than me

1644
01:06:57,240 --> 01:07:01,920
reading this very terrible spreadsheet

1645
01:06:59,220 --> 01:07:03,900
we're going to do the questions so how

1646
01:07:01,920 --> 01:07:07,500
long have we been programming

1647
01:07:03,900 --> 01:07:09,960
uh five years I think

1648
01:07:07,500 --> 01:07:11,339
approximately seven

1649
01:07:09,960 --> 01:07:15,299
two years

1650
01:07:11,339 --> 01:07:17,099
okay and uh favorite emoji

1651
01:07:15,299 --> 01:07:19,500
I think it's the upside down smiley face

1652
01:07:17,099 --> 01:07:23,220
the shark emoji

1653
01:07:19,500 --> 01:07:25,140
I'm gonna say heart eyes emoji okay and

1654
01:07:23,220 --> 01:07:27,059
where are we from

1655
01:07:25,140 --> 01:07:28,140
all of us yes all of you from the same

1656
01:07:27,059 --> 01:07:29,839
School uh

1657
01:07:28,140 --> 01:07:32,880
you're going to be talking to us about

1658
01:07:29,839 --> 01:07:36,980
how difficult robot dogs are I believe

1659
01:07:32,880 --> 01:07:36,980
yes excellent thank you very much

1660
01:07:38,300 --> 01:07:45,299
[Laughter]

1661
01:07:42,240 --> 01:07:46,799
uh good afternoon uh I'm Sam sidebertham

1662
01:07:45,299 --> 01:07:48,000
this is Morgan Potter and Josh GIS

1663
01:07:46,799 --> 01:07:51,240
milber and we're going to be talking

1664
01:07:48,000 --> 01:07:53,640
about Winston the robot dog

1665
01:07:51,240 --> 01:07:56,039
um so Winston is a backer name and he

1666
01:07:53,640 --> 01:07:58,680
stands for a walking inverse kinematics

1667
01:07:56,039 --> 01:08:01,339
based navigation system transmitted over

1668
01:07:58,680 --> 01:08:01,339
Networks

1669
01:08:02,460 --> 01:08:07,619
as his name suggests he is a walking

1670
01:08:05,160 --> 01:08:09,839
quadruped robot he uses inverse

1671
01:08:07,619 --> 01:08:13,319
kinematics to calculate the movement for

1672
01:08:09,839 --> 01:08:15,599
his legs he has a camera to work out the

1673
01:08:13,319 --> 01:08:17,400
navigation and it uses networks to

1674
01:08:15,599 --> 01:08:19,080
communicate all these ideas to the other

1675
01:08:17,400 --> 01:08:20,880
parts

1676
01:08:19,080 --> 01:08:23,460
um we split this up between us so I was

1677
01:08:20,880 --> 01:08:25,560
doing the physical build of the dog and

1678
01:08:23,460 --> 01:08:28,140
the walking Morgan was doing the camera

1679
01:08:25,560 --> 01:08:29,719
navigation and Josh was doing the

1680
01:08:28,140 --> 01:08:32,580
communication

1681
01:08:29,719 --> 01:08:35,520
I did it in Arduino Morgan used a

1682
01:08:32,580 --> 01:08:38,880
Raspberry Pi and Josh and flask

1683
01:08:35,520 --> 01:08:41,759
so this all started in early last year

1684
01:08:38,880 --> 01:08:43,219
when I saw Boston dynamics's spot for

1685
01:08:41,759 --> 01:08:45,960
the very first time

1686
01:08:43,219 --> 01:08:48,900
30 years of research and development all

1687
01:08:45,960 --> 01:08:50,219
put into one really Advanced robot dog

1688
01:08:48,900 --> 01:08:53,600
and

1689
01:08:50,219 --> 01:08:53,600
I thought I could do that

1690
01:08:54,960 --> 01:09:01,940
so my first attempt in June of last year

1691
01:08:58,199 --> 01:09:04,739
looked a little less Advanced

1692
01:09:01,940 --> 01:09:07,859
his main issue were his stick legs that

1693
01:09:04,739 --> 01:09:10,859
kept falling off I submitted him and

1694
01:09:07,859 --> 01:09:11,270
this was my teacher's feedback

1695
01:09:10,859 --> 01:09:14,479
um

1696
01:09:11,270 --> 01:09:14,479
[Music]

1697
01:09:15,980 --> 01:09:21,839
so I decided to do some better

1698
01:09:18,540 --> 01:09:23,580
development for more advanced legs

1699
01:09:21,839 --> 01:09:25,859
um so I looked at how other robots had

1700
01:09:23,580 --> 01:09:28,799
done it some had Motors placed on the

1701
01:09:25,859 --> 01:09:32,219
knees While others use linear actuators

1702
01:09:28,799 --> 01:09:35,460
and all Motors at the hips and I read a

1703
01:09:32,219 --> 01:09:37,980
few papers as well until I came up with

1704
01:09:35,460 --> 01:09:40,319
this design which mimics the linear

1705
01:09:37,980 --> 01:09:43,799
actuator model both Motors were located

1706
01:09:40,319 --> 01:09:46,679
at the hip but we didn't have any linear

1707
01:09:43,799 --> 01:09:49,859
actuators on hand what we did have were

1708
01:09:46,679 --> 01:09:52,440
spare parts from a broken 3D printer

1709
01:09:49,859 --> 01:09:55,320
which we turned into a pulley system

1710
01:09:52,440 --> 01:09:56,760
it worked reasonably reliably so I

1711
01:09:55,320 --> 01:09:58,739
upscaled it

1712
01:09:56,760 --> 01:10:01,440
and then I went to implement the

1713
01:09:58,739 --> 01:10:03,480
movement controls what we wanted was to

1714
01:10:01,440 --> 01:10:05,340
be able to put an input for the full

1715
01:10:03,480 --> 01:10:06,660
extension and then calculate the angles

1716
01:10:05,340 --> 01:10:08,520
needed to get there

1717
01:10:06,660 --> 01:10:10,739
we could create a triangle using the

1718
01:10:08,520 --> 01:10:13,860
legs and then use some simple maths

1719
01:10:10,739 --> 01:10:16,320
which is definitely coded in Python to

1720
01:10:13,860 --> 01:10:17,520
create a very simple inverse kinematics

1721
01:10:16,320 --> 01:10:20,640
function

1722
01:10:17,520 --> 01:10:22,500
uh this is the dog in its current state

1723
01:10:20,640 --> 01:10:24,300
there are some things you may notice

1724
01:10:22,500 --> 01:10:27,120
like the fact that there's actually

1725
01:10:24,300 --> 01:10:29,340
three Murders At The Hip uh this was

1726
01:10:27,120 --> 01:10:31,080
because while I was looking at it I saw

1727
01:10:29,340 --> 01:10:31,920
you needed one to do actual knee

1728
01:10:31,080 --> 01:10:33,960
movement

1729
01:10:31,920 --> 01:10:35,219
one to move the whole leg and then I

1730
01:10:33,960 --> 01:10:37,560
realized you can also move your leg

1731
01:10:35,219 --> 01:10:40,760
outwards I don't know what purpose it

1732
01:10:37,560 --> 01:10:40,760
serves but I added it anyway

1733
01:10:41,340 --> 01:10:46,620
uh he's also got a hollow body design

1734
01:10:43,620 --> 01:10:48,900
this was mainly to minimize the weight

1735
01:10:46,620 --> 01:10:50,699
load that the legs had to carry there

1736
01:10:48,900 --> 01:10:52,320
was the slight drawback that if you need

1737
01:10:50,699 --> 01:10:54,600
to bring this on a plane from Canberra

1738
01:10:52,320 --> 01:10:56,900
to present it it may look slightly like

1739
01:10:54,600 --> 01:10:56,900
a bomb

1740
01:10:57,600 --> 01:11:01,620
um it's not trust so I will now give it

1741
01:11:00,179 --> 01:11:03,120
to Morgan to talk about the computer

1742
01:11:01,620 --> 01:11:05,540
vision

1743
01:11:03,120 --> 01:11:07,500
uh hello I'm the aforementioned Morgan

1744
01:11:05,540 --> 01:11:10,320
uh yeah I did the computer vision

1745
01:11:07,500 --> 01:11:12,120
opponent of Winston which is a subset of

1746
01:11:10,320 --> 01:11:14,640
the navigation system

1747
01:11:12,120 --> 01:11:17,880
um so basically the goal one of the

1748
01:11:14,640 --> 01:11:19,260
goals of Winston is to have a um

1749
01:11:17,880 --> 01:11:22,500
like

1750
01:11:19,260 --> 01:11:23,880
terrain navigation so say you want to

1751
01:11:22,500 --> 01:11:25,380
move like individual legs so you're

1752
01:11:23,880 --> 01:11:27,540
moving over Rocky terrain you're gonna

1753
01:11:25,380 --> 01:11:30,780
have to like know where to put each leg

1754
01:11:27,540 --> 01:11:34,500
uh yeah which is quite difficult to do

1755
01:11:30,780 --> 01:11:36,360
without a good 3D map of the environment

1756
01:11:34,500 --> 01:11:38,280
um yeah so I chose a stereo Vision

1757
01:11:36,360 --> 01:11:40,860
approach to do this which is essentially

1758
01:11:38,280 --> 01:11:43,739
you uh you can obtain depth from two

1759
01:11:40,860 --> 01:11:46,080
cameras uh through a triangulation uh

1760
01:11:43,739 --> 01:11:47,820
because you know the image point in uh

1761
01:11:46,080 --> 01:11:51,000
both image points

1762
01:11:47,820 --> 01:11:53,100
yeah so the main issue with this is the

1763
01:11:51,000 --> 01:11:55,320
correspondence problem so

1764
01:11:53,100 --> 01:11:56,940
you basically don't know which pixels

1765
01:11:55,320 --> 01:11:58,560
match up with the other pixels in either

1766
01:11:56,940 --> 01:12:01,260
image so

1767
01:11:58,560 --> 01:12:03,300
in this example you don't know that the

1768
01:12:01,260 --> 01:12:04,320
tape measure in the left image is the

1769
01:12:03,300 --> 01:12:07,920
same as the tape measure on the Right

1770
01:12:04,320 --> 01:12:08,640
image without doing some computations

1771
01:12:07,920 --> 01:12:10,620
um

1772
01:12:08,640 --> 01:12:12,840
so I originally chose to uh Harris

1773
01:12:10,620 --> 01:12:16,500
Corner detection approach

1774
01:12:12,840 --> 01:12:19,080
um which is essentially aims to yeah

1775
01:12:16,500 --> 01:12:20,640
um match based on the likelihood that it

1776
01:12:19,080 --> 01:12:22,500
is a corner

1777
01:12:20,640 --> 01:12:24,120
um yeah it's the problem with this is

1778
01:12:22,500 --> 01:12:26,580
It's a sparse matching method meaning

1779
01:12:24,120 --> 01:12:29,040
that there's not many points that get

1780
01:12:26,580 --> 01:12:31,140
um matched between the two images and

1781
01:12:29,040 --> 01:12:33,120
some post-processing techniques will

1782
01:12:31,140 --> 01:12:35,760
like um a ball pivoting algorithm would

1783
01:12:33,120 --> 01:12:38,940
have to be used to be able to get an

1784
01:12:35,760 --> 01:12:43,140
actual uh 3D geometry from it

1785
01:12:38,940 --> 01:12:44,580
so I pivoted to block matching which

1786
01:12:43,140 --> 01:12:47,219
essentially involves

1787
01:12:44,580 --> 01:12:49,260
taking a block from the left image and

1788
01:12:47,219 --> 01:12:52,380
comparing it against a set of blocks in

1789
01:12:49,260 --> 01:12:54,659
the right image and Computing a uh a

1790
01:12:52,380 --> 01:12:56,159
cost function at each of the blocks and

1791
01:12:54,659 --> 01:12:59,060
then you choose the block which has the

1792
01:12:56,159 --> 01:12:59,060
lowest cost

1793
01:12:59,760 --> 01:13:04,560
um this is the camera housing design

1794
01:13:01,940 --> 01:13:06,060
I uh there's two things to note about

1795
01:13:04,560 --> 01:13:07,860
this the

1796
01:13:06,060 --> 01:13:11,280
cameras maintain a constant relative

1797
01:13:07,860 --> 01:13:13,020
position so they don't move and the uh

1798
01:13:11,280 --> 01:13:17,340
they are only displaced horizontally

1799
01:13:13,020 --> 01:13:19,260
meaning that the pixels are aligned uh

1800
01:13:17,340 --> 01:13:21,780
the pixels are aligned vertically uh

1801
01:13:19,260 --> 01:13:23,460
when you get rid of distortion meaning

1802
01:13:21,780 --> 01:13:27,000
you only have to scan in one dimension

1803
01:13:23,460 --> 01:13:30,420
so you can just scan across the yeah uh

1804
01:13:27,000 --> 01:13:32,580
the scan line there in blue

1805
01:13:30,420 --> 01:13:34,980
um so this is the result it's not

1806
01:13:32,580 --> 01:13:35,940
exactly a depth map

1807
01:13:34,980 --> 01:13:38,940
um

1808
01:13:35,940 --> 01:13:41,820
yeah the the main the main issue with

1809
01:13:38,940 --> 01:13:44,040
this is um block matching isn't really a

1810
01:13:41,820 --> 01:13:47,400
modern technique it's a bit old so

1811
01:13:44,040 --> 01:13:49,739
modern techniques use neural networks I

1812
01:13:47,400 --> 01:13:52,560
wanted to do block matching first

1813
01:13:49,739 --> 01:13:54,780
because it um because I needed to get a

1814
01:13:52,560 --> 01:13:56,640
better understanding of it but I will

1815
01:13:54,780 --> 01:13:58,080
try to implement neural networks in the

1816
01:13:56,640 --> 01:14:00,179
future yeah

1817
01:13:58,080 --> 01:14:02,280
and on to Josh

1818
01:14:00,179 --> 01:14:05,580
but hello I'm Josh

1819
01:14:02,280 --> 01:14:08,699
um I put a ton into ton

1820
01:14:05,580 --> 01:14:11,460
um now I my goal here was to connect all

1821
01:14:08,699 --> 01:14:13,800
three projects um we have Sam with his

1822
01:14:11,460 --> 01:14:15,719
movement of Winston and Morgan with his

1823
01:14:13,800 --> 01:14:17,520
computer vision and I was disconnecting

1824
01:14:15,719 --> 01:14:19,800
all three of the projects into one big

1825
01:14:17,520 --> 01:14:21,659
one instead of three minor ones

1826
01:14:19,800 --> 01:14:23,820
um with that I created an access point

1827
01:14:21,659 --> 01:14:25,679
to Winston on the web

1828
01:14:23,820 --> 01:14:27,840
um this was done

1829
01:14:25,679 --> 01:14:30,060
um with the Winston video stream as I

1830
01:14:27,840 --> 01:14:31,560
call the Winston Vision video stream

1831
01:14:30,060 --> 01:14:35,520
um which was Morgan's computer vision

1832
01:14:31,560 --> 01:14:37,800
and and it was all done okay hold on it

1833
01:14:35,520 --> 01:14:40,080
was all done with flask there we go

1834
01:14:37,800 --> 01:14:41,520
um because you know we love python it's

1835
01:14:40,080 --> 01:14:43,560
the best thing ever

1836
01:14:41,520 --> 01:14:45,480
um the primary purpose of this as stated

1837
01:14:43,560 --> 01:14:48,780
was to connect all the projects together

1838
01:14:45,480 --> 01:14:50,880
and this was done through HTTP requests

1839
01:14:48,780 --> 01:14:53,340
and radio

1840
01:14:50,880 --> 01:14:55,020
um yeah radio so radio first Sam's

1841
01:14:53,340 --> 01:14:57,120
Arduino just to connect it all and we

1842
01:14:55,020 --> 01:14:58,980
had HTTP requests from the Raspberry Pi

1843
01:14:57,120 --> 01:15:00,420
with Morgan and this would all display

1844
01:14:58,980 --> 01:15:02,699
on the website

1845
01:15:00,420 --> 01:15:04,980
um with the wins division data stream so

1846
01:15:02,699 --> 01:15:06,840
look pretty much like that

1847
01:15:04,980 --> 01:15:10,080
um you have both eyes and how they would

1848
01:15:06,840 --> 01:15:11,880
be shown with the three streams and then

1849
01:15:10,080 --> 01:15:13,140
you've also got the processed image down

1850
01:15:11,880 --> 01:15:15,300
the bottom

1851
01:15:13,140 --> 01:15:18,060
um which is just giving everyone an idea

1852
01:15:15,300 --> 01:15:20,040
of what the dog is actually doing and

1853
01:15:18,060 --> 01:15:23,040
what it can see and it just provides

1854
01:15:20,040 --> 01:15:24,960
that that access point as stated to what

1855
01:15:23,040 --> 01:15:27,300
Winston is anyway I'm going to pass it

1856
01:15:24,960 --> 01:15:30,120
back to Sam now and what he was done

1857
01:15:27,300 --> 01:15:31,679
yeah so uh where are we at with Winston

1858
01:15:30,120 --> 01:15:33,900
right now

1859
01:15:31,679 --> 01:15:37,040
um we have him here and I will show you

1860
01:15:33,900 --> 01:15:37,040
what he can do

1861
01:15:46,140 --> 01:15:53,130
not a lot

1862
01:15:48,940 --> 01:15:53,130
[Applause]

1863
01:15:53,640 --> 01:15:59,100
um he he does respond to commands but

1864
01:15:56,280 --> 01:16:01,739
not well and he's not walking for a few

1865
01:15:59,100 --> 01:16:03,420
reasons one of which is biomechanics is

1866
01:16:01,739 --> 01:16:06,480
hard

1867
01:16:03,420 --> 01:16:08,580
um if you have too much tension then the

1868
01:16:06,480 --> 01:16:09,900
police will tear themselves apart if you

1869
01:16:08,580 --> 01:16:12,719
have too little then there's too much

1870
01:16:09,900 --> 01:16:17,600
slack for them to move they also

1871
01:16:12,719 --> 01:16:17,600
sometimes don't respond reliably

1872
01:16:17,640 --> 01:16:22,020
and do that

1873
01:16:19,560 --> 01:16:24,300
you can also see that there's a battery

1874
01:16:22,020 --> 01:16:25,760
in a burn bag that's not present on the

1875
01:16:24,300 --> 01:16:29,460
dog which leads into the second reason

1876
01:16:25,760 --> 01:16:32,400
that equipment gets damaged we went

1877
01:16:29,460 --> 01:16:34,560
through the servo driver board because

1878
01:16:32,400 --> 01:16:37,080
we plugged a 12 volt battery even though

1879
01:16:34,560 --> 01:16:38,820
it has six volts Max

1880
01:16:37,080 --> 01:16:40,320
um it's also the last one we had with a

1881
01:16:38,820 --> 01:16:42,600
capacitor so I had to pray that that

1882
01:16:40,320 --> 01:16:44,600
wasn't important

1883
01:16:42,600 --> 01:16:44,600
um

1884
01:16:44,820 --> 01:16:50,400
we also went through two arduinos and a

1885
01:16:47,699 --> 01:16:52,140
Wi-Fi chip we were too busy putting the

1886
01:16:50,400 --> 01:16:53,370
fires out to take photos so here's an

1887
01:16:52,140 --> 01:16:55,440
artist rendition

1888
01:16:53,370 --> 01:16:57,120
[Music]

1889
01:16:55,440 --> 01:16:59,280
um and then the battery that I just

1890
01:16:57,120 --> 01:17:01,620
mentioned if you leave lying around a

1891
01:16:59,280 --> 01:17:03,600
year 11 will find it and find that

1892
01:17:01,620 --> 01:17:07,580
Sparks Fly when you connect ground and

1893
01:17:03,600 --> 01:17:07,580
power and bad stuff happens

1894
01:17:07,800 --> 01:17:13,340
um overall this was a 160 loss

1895
01:17:14,340 --> 01:17:20,159
um but we are optimistic to turn this

1896
01:17:17,580 --> 01:17:22,500
around in the future

1897
01:17:20,159 --> 01:17:24,840
we do plan to continue working on

1898
01:17:22,500 --> 01:17:26,640
Winston this isn't the final project and

1899
01:17:24,840 --> 01:17:29,580
if we've piqued your interest at all we

1900
01:17:26,640 --> 01:17:31,640
do upload posts to the Instagram

1901
01:17:29,580 --> 01:17:31,640
um

1902
01:17:32,400 --> 01:17:37,380
um yeah good and the bad so yeah thank

1903
01:17:35,580 --> 01:17:39,060
you for listening

1904
01:17:37,380 --> 01:17:42,329
um yeah hi

1905
01:17:39,060 --> 01:17:42,329
[Applause]

1906
01:17:47,340 --> 01:17:51,080
and Thomas I think is next

1907
01:17:52,320 --> 01:17:55,159
come on down

1908
01:17:55,800 --> 01:18:00,500
laughs

1909
01:17:58,380 --> 01:18:02,640
[Music]

1910
01:18:00,500 --> 01:18:04,820
I can't hear anything can you hear

1911
01:18:02,640 --> 01:18:04,820
anything

1912
01:18:06,440 --> 01:18:11,360
all right there's a ghost oh that's

1913
01:18:11,760 --> 01:18:17,520
Okay so we've got Thomas you've been

1914
01:18:14,580 --> 01:18:19,800
programming since years seven

1915
01:18:17,520 --> 01:18:22,020
and um look I'm going to read this out

1916
01:18:19,800 --> 01:18:25,679
because Thomas wrote it and it's just a

1917
01:18:22,020 --> 01:18:26,940
spook for ourselves here he used grok

1918
01:18:25,679 --> 01:18:29,520
learning

1919
01:18:26,940 --> 01:18:32,699
to begin his programming knowledge

1920
01:18:29,520 --> 01:18:34,320
career so well done Brock

1921
01:18:32,699 --> 01:18:37,620
yes

1922
01:18:34,320 --> 01:18:40,500
your favorite emoji is

1923
01:18:37,620 --> 01:18:43,260
there a rock face or the moai this is

1924
01:18:40,500 --> 01:18:45,719
you who wrote it not a test I remember

1925
01:18:43,260 --> 01:18:48,420
okay good good good

1926
01:18:45,719 --> 01:18:52,100
um and you like it because it's used on

1927
01:18:48,420 --> 01:18:52,100
social media sites such as Reddit

1928
01:18:53,400 --> 01:18:56,699
the most recent thing that you've

1929
01:18:55,080 --> 01:18:59,219
learned about computers is that

1930
01:18:56,699 --> 01:19:02,340
Microsoft is finally starting to support

1931
01:18:59,219 --> 01:19:04,800
open source projects such as terminal

1932
01:19:02,340 --> 01:19:06,179
which is a really nice thing totally

1933
01:19:04,800 --> 01:19:09,179
right

1934
01:19:06,179 --> 01:19:09,179
and

1935
01:19:10,020 --> 01:19:14,760
oh well done and so here we have Thomas

1936
01:19:12,600 --> 01:19:19,280
speaking about ASCII video player and

1937
01:19:14,760 --> 01:19:19,280
tic tac toe thank you Tom

1938
01:19:23,219 --> 01:19:27,540
ready uh hi I'm Thomas

1939
01:19:25,920 --> 01:19:29,580
um I'd like to show you till my projects

1940
01:19:27,540 --> 01:19:31,920
I've been working on as is mentioned uh

1941
01:19:29,580 --> 01:19:36,600
my ASCII video filter and my noughts and

1942
01:19:31,920 --> 01:19:36,600
Crosses machine learning model first

1943
01:19:36,840 --> 01:19:42,420
I'll talk about my video filter it takes

1944
01:19:39,719 --> 01:19:45,179
either webcam or video input and outputs

1945
01:19:42,420 --> 01:19:48,960
it into a terminal with an amazing 140

1946
01:19:45,179 --> 01:19:51,120
170 by 44 resolution not shown in these

1947
01:19:48,960 --> 01:19:52,920
images it's too small

1948
01:19:51,120 --> 01:19:55,080
um you can either use colors from The

1949
01:19:52,920 --> 01:19:56,699
Source or it can apply a color filter by

1950
01:19:55,080 --> 01:19:59,820
finding the intensity of each pixel

1951
01:19:56,699 --> 01:20:03,260
which is shown in the green python logo

1952
01:19:59,820 --> 01:20:06,199
uh why did I make it other than why not

1953
01:20:03,260 --> 01:20:09,719
so in the early versions of VLC like

1954
01:20:06,199 --> 01:20:11,699
1.0.0 there is an ASCII art filter that

1955
01:20:09,719 --> 01:20:13,520
takes the video being played and outputs

1956
01:20:11,699 --> 01:20:16,920
a grid of colored characters

1957
01:20:13,520 --> 01:20:19,920
and backs them with backgrounds I use a

1958
01:20:16,920 --> 01:20:21,719
list of maybe 16 colors mixes them in

1959
01:20:19,920 --> 01:20:24,540
differing amounts to approximate

1960
01:20:21,719 --> 01:20:26,280
different colors uh for example to

1961
01:20:24,540 --> 01:20:28,679
display a slightly darker shade of green

1962
01:20:26,280 --> 01:20:30,600
it will set the background to green and

1963
01:20:28,679 --> 01:20:32,880
display a small black character over the

1964
01:20:30,600 --> 01:20:35,940
top this can be seen in the top of the

1965
01:20:32,880 --> 01:20:38,880
center on the center of the top

1966
01:20:35,940 --> 01:20:42,120
initially I wanted to close I wanted to

1967
01:20:38,880 --> 01:20:43,860
closely replicate vlc's effect and use

1968
01:20:42,120 --> 01:20:45,780
the 16 colors from Windows command

1969
01:20:43,860 --> 01:20:48,420
prompt and so I was going to set up the

1970
01:20:45,780 --> 01:20:50,880
program to convert each RGB value to its

1971
01:20:48,420 --> 01:20:52,920
closest color in the list what I didn't

1972
01:20:50,880 --> 01:20:55,620
understand at the time is performing

1973
01:20:52,920 --> 01:20:57,719
lots of queries is slow and both Python

1974
01:20:55,620 --> 01:20:58,640
and my computer couldn't do 16 queries

1975
01:20:57,719 --> 01:21:00,739
over

1976
01:20:58,640 --> 01:21:04,800
7480

1977
01:21:00,739 --> 01:21:07,320
7480 pixels at 30 frames a second to try

1978
01:21:04,800 --> 01:21:09,000
and speed up the search I installed a

1979
01:21:07,320 --> 01:21:11,880
python aux trees implementation from

1980
01:21:09,000 --> 01:21:13,980
GitHub not using pip which is kind of

1981
01:21:11,880 --> 01:21:15,900
painful

1982
01:21:13,980 --> 01:21:18,000
so got found out on GitHub manually

1983
01:21:15,900 --> 01:21:19,380
installed it into pycharm took quite a

1984
01:21:18,000 --> 01:21:21,000
while

1985
01:21:19,380 --> 01:21:23,640
um see I was going to use that as I

1986
01:21:21,000 --> 01:21:25,340
realized colors are basically points in

1987
01:21:23,640 --> 01:21:29,100
3D space

1988
01:21:25,340 --> 01:21:32,760
then turns out uh Powershell supports

1989
01:21:29,100 --> 01:21:34,920
are like any RGB value so I wasted my

1990
01:21:32,760 --> 01:21:35,640
time it's kind of sad

1991
01:21:34,920 --> 01:21:38,880
um

1992
01:21:35,640 --> 01:21:40,739
so it got easier but I wasted my time

1993
01:21:38,880 --> 01:21:43,679
it's kind of sad

1994
01:21:40,739 --> 01:21:46,460
um and then from there it was much

1995
01:21:43,679 --> 01:21:46,460
easier as I said

1996
01:21:46,620 --> 01:21:52,920
I installed opencv to resize The Source

1997
01:21:51,120 --> 01:21:55,620
array for either from the webcam or from

1998
01:21:52,920 --> 01:21:58,679
the video using linear interpolation or

1999
01:21:55,620 --> 01:22:00,000
cubic if I'm getting fancy after looking

2000
01:21:58,679 --> 01:22:01,679
at a whole bunch of Stack exchange

2001
01:22:00,000 --> 01:22:05,280
answers found out how to write the

2002
01:22:01,679 --> 01:22:06,719
Escape sequences and I put on a random

2003
01:22:05,280 --> 01:22:07,500
character to complete the hacker Man

2004
01:22:06,719 --> 01:22:09,960
look

2005
01:22:07,500 --> 01:22:11,820
each escaped string was appended to a

2006
01:22:09,960 --> 01:22:13,440
giant string which is to be printed each

2007
01:22:11,820 --> 01:22:14,880
frame along with new lines in the

2008
01:22:13,440 --> 01:22:16,920
correct places

2009
01:22:14,880 --> 01:22:18,780
once the functions were complete I

2010
01:22:16,920 --> 01:22:20,159
tested them in Windows terminal and got

2011
01:22:18,780 --> 01:22:22,920
the string as a literal instead of

2012
01:22:20,159 --> 01:22:25,080
colorful text my advice that myself were

2013
01:22:22,920 --> 01:22:27,179
very confused since the escapes looked

2014
01:22:25,080 --> 01:22:29,219
correct but they were not registering

2015
01:22:27,179 --> 01:22:31,020
eventually we had the idea to print each

2016
01:22:29,219 --> 01:22:33,060
escape sequence separately and that

2017
01:22:31,020 --> 01:22:34,920
worked perfectly

2018
01:22:33,060 --> 01:22:37,159
so I'll give a quick demonstration for

2019
01:22:34,920 --> 01:22:37,159
that one

2020
01:22:42,120 --> 01:22:47,699
and hopefully

2021
01:22:44,580 --> 01:22:48,020
yeah certainly see me

2022
01:22:47,699 --> 01:22:51,309
um

2023
01:22:48,020 --> 01:22:51,309
[Applause]

2024
01:22:57,260 --> 01:23:03,739
that was a smaller project thought

2025
01:22:59,580 --> 01:23:03,739
better run more so my next project

2026
01:23:04,260 --> 01:23:08,460
not that one

2027
01:23:06,900 --> 01:23:10,020
uh

2028
01:23:08,460 --> 01:23:11,699
there we go

2029
01:23:10,020 --> 01:23:15,360
my notes and Crosses machine learning

2030
01:23:11,699 --> 01:23:17,040
model so my other yeah it uses a into my

2031
01:23:15,360 --> 01:23:19,080
interpretation of the Monte Carlo

2032
01:23:17,040 --> 01:23:21,719
research algorithm from its page on

2033
01:23:19,080 --> 01:23:24,360
Wikipedia and a sqlite database which

2034
01:23:21,719 --> 01:23:26,280
contains every possible board State the

2035
01:23:24,360 --> 01:23:29,040
number of times that that state has

2036
01:23:26,280 --> 01:23:30,840
contributed to a win and the Empower and

2037
01:23:29,040 --> 01:23:34,320
how many times it has been used

2038
01:23:30,840 --> 01:23:37,620
started designing this moment I started

2039
01:23:34,320 --> 01:23:39,600
designing uh the mod that is started the

2040
01:23:37,620 --> 01:23:41,460
model in January last year and was first

2041
01:23:39,600 --> 01:23:42,840
working in August making it my longest

2042
01:23:41,460 --> 01:23:45,380
project so far

2043
01:23:42,840 --> 01:23:49,260
as you saw

2044
01:23:45,380 --> 01:23:52,920
it shows a ASCII grid of characters

2045
01:23:49,260 --> 01:23:54,480
um it it's playable so each number is in

2046
01:23:52,920 --> 01:23:57,179
the position that it would be on a

2047
01:23:54,480 --> 01:23:59,460
number pad making it easy to type in

2048
01:23:57,179 --> 01:24:01,920
to make a movie type in a single digit

2049
01:23:59,460 --> 01:24:04,199
press enter and then it'll make a move

2050
01:24:01,920 --> 01:24:06,120
then the computer will go and it'll

2051
01:24:04,199 --> 01:24:08,100
calculate which move is pretty good and

2052
01:24:06,120 --> 01:24:09,300
then output that and then it's your turn

2053
01:24:08,100 --> 01:24:11,340
again

2054
01:24:09,300 --> 01:24:13,980
uh this repeats until the board is

2055
01:24:11,340 --> 01:24:15,060
filled or someone wins

2056
01:24:13,980 --> 01:24:18,060
so

2057
01:24:15,060 --> 01:24:19,620
since each position is a single digit I

2058
01:24:18,060 --> 01:24:21,659
realized I can store the current state

2059
01:24:19,620 --> 01:24:24,060
as a string by appending each player to

2060
01:24:21,659 --> 01:24:26,580
the end for example one of the simplest

2061
01:24:24,060 --> 01:24:28,980
games can be shown as one four two five

2062
01:24:26,580 --> 01:24:31,800
three where in as you can see in this

2063
01:24:28,980 --> 01:24:33,600
example so one two and three are in the

2064
01:24:31,800 --> 01:24:36,179
bottom row and made by the first player

2065
01:24:33,600 --> 01:24:39,000
X and four and five are in the middle

2066
01:24:36,179 --> 01:24:41,820
row made by a second player oh

2067
01:24:39,000 --> 01:24:43,920
now the program would then store each

2068
01:24:41,820 --> 01:24:45,900
state as an identifier in the sqlite

2069
01:24:43,920 --> 01:24:48,600
database

2070
01:24:45,900 --> 01:24:50,699
to decide which move to make the program

2071
01:24:48,600 --> 01:24:52,580
calculates the child States and fetches

2072
01:24:50,699 --> 01:24:54,960
them from from the stats in the table

2073
01:24:52,580 --> 01:24:57,000
the quality of the move is calculated

2074
01:24:54,960 --> 01:24:58,920
from this formula which are which I

2075
01:24:57,000 --> 01:25:02,340
borrowed from the Monte Carlo search

2076
01:24:58,920 --> 01:25:04,620
Wikipedia article so wi as you can see

2077
01:25:02,340 --> 01:25:07,500
up there is how many times that move has

2078
01:25:04,620 --> 01:25:10,440
contributed to a win our small ni is how

2079
01:25:07,500 --> 01:25:12,600
many times it's been used big ni is how

2080
01:25:10,440 --> 01:25:15,540
many times the parent has been used

2081
01:25:12,600 --> 01:25:17,280
like the previous move and C is the

2082
01:25:15,540 --> 01:25:20,400
exploration parameter

2083
01:25:17,280 --> 01:25:21,540
chosen arbitrarily I chose the square

2084
01:25:20,400 --> 01:25:24,440
root of two because that's what

2085
01:25:21,540 --> 01:25:24,440
Wikipedia recommended

2086
01:25:25,440 --> 01:25:31,140
um next

2087
01:25:26,880 --> 01:25:33,960
so and when I first started realized

2088
01:25:31,140 --> 01:25:36,060
um a small ni will be zero before a move

2089
01:25:33,960 --> 01:25:38,940
has been used that leads to a whole

2090
01:25:36,060 --> 01:25:40,980
bunch of Divisions by zero not good

2091
01:25:38,940 --> 01:25:43,800
um so to make sure every move will get

2092
01:25:40,980 --> 01:25:45,480
used I set it to 10 if the move has

2093
01:25:43,800 --> 01:25:47,219
never been used before because that way

2094
01:25:45,480 --> 01:25:48,260
it'll get it's guaranteed to get used at

2095
01:25:47,219 --> 01:25:51,780
some point

2096
01:25:48,260 --> 01:25:54,780
so from there once I calculated every

2097
01:25:51,780 --> 01:25:58,199
possible move realize there are 360

2098
01:25:54,780 --> 01:26:00,300
000 permutations of one to nine to

2099
01:25:58,199 --> 01:26:02,219
reduce that number I removed the history

2100
01:26:00,300 --> 01:26:04,320
from each board by splitting the state

2101
01:26:02,219 --> 01:26:06,179
right by splitting the state string into

2102
01:26:04,320 --> 01:26:06,900
each player's moves then sorted them by

2103
01:26:06,179 --> 01:26:09,480
number

2104
01:26:06,900 --> 01:26:11,219
before sorting each state I checked for

2105
01:26:09,480 --> 01:26:13,260
redundancy by checking if the state was

2106
01:26:11,219 --> 01:26:15,239
one in the previous turn are these

2107
01:26:13,260 --> 01:26:17,280
strategies produce the number of rows in

2108
01:26:15,239 --> 01:26:20,820
the table from more than 360

2109
01:26:17,280 --> 01:26:20,820
000 to 5427.77.

2110
01:26:25,500 --> 01:26:29,340
in my program since I had multiple ways

2111
01:26:27,780 --> 01:26:31,199
of representing the current state of the

2112
01:26:29,340 --> 01:26:32,580
board I made functions to convert

2113
01:26:31,199 --> 01:26:35,340
between them

2114
01:26:32,580 --> 01:26:37,679
to convert to the database name where

2115
01:26:35,340 --> 01:26:39,360
each player's moves are Consolidated the

2116
01:26:37,679 --> 01:26:42,000
function splits the string into odd and

2117
01:26:39,360 --> 01:26:43,980
even index parts then joins them to

2118
01:26:42,000 --> 01:26:45,780
convert back the function splits the

2119
01:26:43,980 --> 01:26:47,880
string into two pieces but the first

2120
01:26:45,780 --> 01:26:49,679
part is either equal in length or one

2121
01:26:47,880 --> 01:26:51,600
larger than the second part then

2122
01:26:49,679 --> 01:26:53,219
interlaces the strings together so the

2123
01:26:51,600 --> 01:26:54,840
string represents a possible gain

2124
01:26:53,219 --> 01:26:58,500
between two players

2125
01:26:54,840 --> 01:27:00,179
but each player's moves are sorted

2126
01:26:58,500 --> 01:27:02,699
to make some of the calculations easier

2127
01:27:00,179 --> 01:27:04,980
I made a 2d vector class which converts

2128
01:27:02,699 --> 01:27:06,120
from the 1D index into a three by three

2129
01:27:04,980 --> 01:27:08,580
space

2130
01:27:06,120 --> 01:27:11,040
oh it was quite helpful

2131
01:27:08,580 --> 01:27:13,139
during the Project's development I got a

2132
01:27:11,040 --> 01:27:15,659
new computer I got this computer

2133
01:27:13,139 --> 01:27:17,040
so I uploaded the files to GitHub so I

2134
01:27:15,659 --> 01:27:20,060
could transfer them between computers

2135
01:27:17,040 --> 01:27:21,620
and so I can share it even with you guys

2136
01:27:20,060 --> 01:27:24,600
unfortunately

2137
01:27:21,620 --> 01:27:26,360
most files downloaded normally except

2138
01:27:24,600 --> 01:27:30,420
for my database which is a bit of a pain

2139
01:27:26,360 --> 01:27:31,620
so that rendered the program unusable to

2140
01:27:30,420 --> 01:27:34,500
get around this I made two more

2141
01:27:31,620 --> 01:27:36,960
functions that takes the data from a

2142
01:27:34,500 --> 01:27:39,420
good copy and then puts that into a text

2143
01:27:36,960 --> 01:27:41,580
file one entry per row and then another

2144
01:27:39,420 --> 01:27:43,800
that reverts it puts it back into a

2145
01:27:41,580 --> 01:27:45,659
different database

2146
01:27:43,800 --> 01:27:49,020
um so once I got the program working

2147
01:27:45,659 --> 01:27:50,820
like at the first part

2148
01:27:49,020 --> 01:27:53,159
um it's around 1am so to spot my

2149
01:27:50,820 --> 01:27:54,780
excitement thought I should go to bed

2150
01:27:53,159 --> 01:27:56,400
um so I set the training program to

2151
01:27:54,780 --> 01:27:58,620
trade 1 million games against itself

2152
01:27:56,400 --> 01:28:00,659
when I woke up I checked the program you

2153
01:27:58,620 --> 01:28:02,520
know the finished training when I played

2154
01:28:00,659 --> 01:28:04,080
against it it was able to stop me from

2155
01:28:02,520 --> 01:28:06,420
winning almost all the time which is

2156
01:28:04,080 --> 01:28:09,000
pretty good unfortunately I realized

2157
01:28:06,420 --> 01:28:11,159
every time the best move is chosen in

2158
01:28:09,000 --> 01:28:13,320
the training it degrades the quality so

2159
01:28:11,159 --> 01:28:15,600
sometimes bad moves will be chosen for a

2160
01:28:13,320 --> 01:28:18,179
while until they do great as well

2161
01:28:15,600 --> 01:28:19,860
so far the only remedy I have to fix the

2162
01:28:18,179 --> 01:28:21,659
bad moves is to train the model for

2163
01:28:19,860 --> 01:28:24,179
another few thousand moves to change

2164
01:28:21,659 --> 01:28:26,280
which move is decided to be the best

2165
01:28:24,179 --> 01:28:28,080
from the complexity and amount of time I

2166
01:28:26,280 --> 01:28:29,940
spent on this project I learned some

2167
01:28:28,080 --> 01:28:32,100
important project management tips such

2168
01:28:29,940 --> 01:28:34,260
as using comments clear naming schemes

2169
01:28:32,100 --> 01:28:36,659
and creating small helper functions to

2170
01:28:34,260 --> 01:28:40,100
complete common tasks so I'll do a quick

2171
01:28:36,659 --> 01:28:40,100
demonstration hopefully

2172
01:28:49,260 --> 01:28:52,340
what's this one up

2173
01:28:52,460 --> 01:28:55,639
this one

2174
01:28:55,920 --> 01:29:00,420
well

2175
01:28:57,300 --> 01:29:01,560
cool so in in this one the computer's

2176
01:29:00,420 --> 01:29:04,500
gone first

2177
01:29:01,560 --> 01:29:07,260
where they so this one and

2178
01:29:04,500 --> 01:29:08,460
yep so this one's um but the default and

2179
01:29:07,260 --> 01:29:11,040
this one there should be an o in there

2180
01:29:08,460 --> 01:29:12,600
somewhere but X we had number eight at

2181
01:29:11,040 --> 01:29:14,520
the top there

2182
01:29:12,600 --> 01:29:16,020
so if I type in a number that isn't

2183
01:29:14,520 --> 01:29:18,239
eight

2184
01:29:16,020 --> 01:29:20,400
say five to go on The Middle

2185
01:29:18,239 --> 01:29:22,260
up it puts my move in the middle and

2186
01:29:20,400 --> 01:29:25,460
then plays another move

2187
01:29:22,260 --> 01:29:25,460
so it's gone down the bottom

2188
01:29:26,520 --> 01:29:30,780
so now what's this one oh it's going to

2189
01:29:28,800 --> 01:29:33,000
top corner so it's really bad at the

2190
01:29:30,780 --> 01:29:35,100
moment because I've replaced it done

2191
01:29:33,000 --> 01:29:37,380
replace the data set for a fresh start

2192
01:29:35,100 --> 01:29:40,860
see what see what would happen

2193
01:29:37,380 --> 01:29:42,780
um so now maybe it might win if I go

2194
01:29:40,860 --> 01:29:44,219
three

2195
01:29:42,780 --> 01:29:46,199
no it's a dog

2196
01:29:44,219 --> 01:29:49,980
watch me

2197
01:29:46,199 --> 01:29:51,600
that one and it did it it won it's very

2198
01:29:49,980 --> 01:29:53,280
it's pretty good

2199
01:29:51,600 --> 01:29:56,120
uh thank you all for listening and hope

2200
01:29:53,280 --> 01:29:56,120
you enjoy the rest of your day

2201
01:29:56,970 --> 01:30:02,300
[Laughter]

2202
01:30:00,000 --> 01:30:06,080
yes

2203
01:30:02,300 --> 01:30:09,320
amazing all right we have

2204
01:30:06,080 --> 01:30:13,020
one last talk

2205
01:30:09,320 --> 01:30:15,900
we can do it we're nearly there uh

2206
01:30:13,020 --> 01:30:18,300
Daniel is coming up on Deck

2207
01:30:15,900 --> 01:30:19,500
um give him a shout out as I yes yeah

2208
01:30:18,300 --> 01:30:22,980
all right Daniel's gonna be talking

2209
01:30:19,500 --> 01:30:24,840
about piano music generation with python

2210
01:30:22,980 --> 01:30:28,199
and he has been programming for two

2211
01:30:24,840 --> 01:30:32,159
years his favorite emoji is the grinning

2212
01:30:28,199 --> 01:30:33,300
smiley face emoji solid Choice solid

2213
01:30:32,159 --> 01:30:35,880
Choice

2214
01:30:33,300 --> 01:30:38,520
um and you recently learned that neural

2215
01:30:35,880 --> 01:30:41,460
networks can contain complex numbers too

2216
01:30:38,520 --> 01:30:42,239
that sounds terrifying

2217
01:30:41,460 --> 01:30:45,300
um

2218
01:30:42,239 --> 01:30:46,020
I wonder what led to that Discovery

2219
01:30:45,300 --> 01:30:49,580
um

2220
01:30:46,020 --> 01:30:49,580
do we have slides on Deck

2221
01:30:53,460 --> 01:30:56,960
um

2222
01:30:54,420 --> 01:30:56,960
hang on

2223
01:30:57,000 --> 01:30:59,960
yeah try

2224
01:31:09,060 --> 01:31:14,120
while that's happening how cool have

2225
01:31:11,340 --> 01:31:14,120
that students been

2226
01:31:15,480 --> 01:31:19,920
phenomenal

2227
01:31:17,400 --> 01:31:22,260
all right

2228
01:31:19,920 --> 01:31:23,520
it's pretty good

2229
01:31:22,260 --> 01:31:25,199
um

2230
01:31:23,520 --> 01:31:27,480
I am a little bit tempted to play with

2231
01:31:25,199 --> 01:31:29,040
the dog

2232
01:31:27,480 --> 01:31:31,739
a little bit concerned it might explode

2233
01:31:29,040 --> 01:31:34,139
if I touch it though so I like I don't

2234
01:31:31,739 --> 01:31:36,960
want to be the cause of more equipment

2235
01:31:34,139 --> 01:31:38,080
damage all right excellent writer

2236
01:31:36,960 --> 01:31:41,600
Applause to Daniel

2237
01:31:38,080 --> 01:31:41,600
[Applause]

2238
01:31:42,239 --> 01:31:45,840
hi my name is Daniel and I'm a year tour

2239
01:31:44,280 --> 01:31:48,179
student at North City boys high school

2240
01:31:45,840 --> 01:31:50,400
over the past nine months I've been

2241
01:31:48,179 --> 01:31:52,080
working on my project called gambioso

2242
01:31:50,400 --> 01:31:54,420
which is an application that generates

2243
01:31:52,080 --> 01:31:55,980
piano music using a type of neural

2244
01:31:54,420 --> 01:31:58,199
network called the generative

2245
01:31:55,980 --> 01:32:00,860
adversarial Network it's a beginner

2246
01:31:58,199 --> 01:32:00,860
demonstration

2247
01:32:08,100 --> 01:32:13,920
so I can just a few parameters here

2248
01:32:11,600 --> 01:32:16,920
the scale

2249
01:32:13,920 --> 01:32:19,080
the dissonance and rate density

2250
01:32:16,920 --> 01:32:22,690
and my press generate it generates both

2251
01:32:19,080 --> 01:32:39,659
sheet music sheet music and audio

2252
01:32:22,690 --> 01:32:42,659
[Music]

2253
01:32:39,659 --> 01:32:42,659
foreign

2254
01:32:45,170 --> 01:32:58,239
[Music]

2255
01:33:15,199 --> 01:33:19,860
Network to generate the music also to

2256
01:33:18,540 --> 01:33:21,000
train the neural network you need a lot

2257
01:33:19,860 --> 01:33:23,400
of data

2258
01:33:21,000 --> 01:33:26,340
for this project I used the Maestro data

2259
01:33:23,400 --> 01:33:27,659
set which consists of 1 300 MIDI files

2260
01:33:26,340 --> 01:33:29,639
of piano music

2261
01:33:27,659 --> 01:33:31,560
midi file looks like this

2262
01:33:29,639 --> 01:33:33,239
and swimming in a bit you can see the

2263
01:33:31,560 --> 01:33:36,179
individual nodes which are represented

2264
01:33:33,239 --> 01:33:38,820
by the white lines the horizontal axis

2265
01:33:36,179 --> 01:33:42,920
represents the time and duration and the

2266
01:33:38,820 --> 01:33:42,920
vertical axis represents the pitch

2267
01:33:44,400 --> 01:33:49,020
by neural network can't process a midi

2268
01:33:46,920 --> 01:33:50,340
file directly the music has to be

2269
01:33:49,020 --> 01:33:53,040
included first

2270
01:33:50,340 --> 01:33:55,500
so I use the V6 engine library to

2271
01:33:53,040 --> 01:33:57,780
extract the data for each node and each

2272
01:33:55,500 --> 01:34:00,060
node can be represented by three numbers

2273
01:33:57,780 --> 01:34:02,159
the offset which is the number of Beats

2274
01:34:00,060 --> 01:34:03,179
that has the labs when the node is first

2275
01:34:02,159 --> 01:34:04,980
played

2276
01:34:03,179 --> 01:34:07,739
the duration which is the number of

2277
01:34:04,980 --> 01:34:10,620
Beats that the note is held down for and

2278
01:34:07,739 --> 01:34:14,239
the pH which is a number corresponding

2279
01:34:10,620 --> 01:34:14,239
to one of the 88 keys on the piano

2280
01:34:14,880 --> 01:34:20,239
so the entire piece can be represented

2281
01:34:17,040 --> 01:34:20,239
by a list of numbers

2282
01:34:22,980 --> 01:34:27,120
so then are using this data

2283
01:34:25,260 --> 01:34:29,060
I encoded each piece as a

2284
01:34:27,120 --> 01:34:31,800
two-dimensional array of series and ones

2285
01:34:29,060 --> 01:34:33,960
which is visualized by this image here

2286
01:34:31,800 --> 01:34:37,760
so the white pixels are ones and the

2287
01:34:33,960 --> 01:34:37,760
black pixels are zeros

2288
01:34:38,040 --> 01:34:44,600
so essentially I turn the midi file into

2289
01:34:40,880 --> 01:34:44,600
an image like this

2290
01:34:45,060 --> 01:34:49,320
and then the images are split into

2291
01:34:47,060 --> 01:34:51,239
smaller sections

2292
01:34:49,320 --> 01:34:53,219
and there are 200 000 of these images

2293
01:34:51,239 --> 01:34:55,910
that are used to train the generative

2294
01:34:53,219 --> 01:34:57,679
adversarial Network

2295
01:34:55,910 --> 01:35:00,239
[Music]

2296
01:34:57,679 --> 01:35:02,100
explain how a generative adversarial

2297
01:35:00,239 --> 01:35:05,040
network works

2298
01:35:02,100 --> 01:35:08,820
uh so it consists of two neural networks

2299
01:35:05,040 --> 01:35:11,060
a generator and a discriminator and each

2300
01:35:08,820 --> 01:35:14,219
training cycle involves a few steps

2301
01:35:11,060 --> 01:35:15,900
firstly real images taken from the piano

2302
01:35:14,219 --> 01:35:18,179
music data set

2303
01:35:15,900 --> 01:35:21,179
and fake images generated by the

2304
01:35:18,179 --> 01:35:22,800
generator are fed into the discriminator

2305
01:35:21,179 --> 01:35:26,100
neural network

2306
01:35:22,800 --> 01:35:28,199
then step two it decides whether the

2307
01:35:26,100 --> 01:35:31,320
image is real or fake by calculating a

2308
01:35:28,199 --> 01:35:33,420
value between 0 and 1. where one means

2309
01:35:31,320 --> 01:35:36,000
that it thinks it's real and three means

2310
01:35:33,420 --> 01:35:38,940
it thinks it's fake and this value is

2311
01:35:36,000 --> 01:35:40,980
used to determine how well the generator

2312
01:35:38,940 --> 01:35:42,500
and discriminator neural networks are

2313
01:35:40,980 --> 01:35:45,300
doing

2314
01:35:42,500 --> 01:35:47,880
then step free the discriminator is

2315
01:35:45,300 --> 01:35:51,480
updated so that it can

2316
01:35:47,880 --> 01:35:53,239
recognize fake images better and the

2317
01:35:51,480 --> 01:35:56,280
generator is updated so that it can

2318
01:35:53,239 --> 01:35:57,659
generate more realistic fake and fake

2319
01:35:56,280 --> 01:35:59,600
images

2320
01:35:57,659 --> 01:36:02,820
these steps are repeated many times

2321
01:35:59,600 --> 01:36:06,860
until the generator is able to generate

2322
01:36:02,820 --> 01:36:06,860
a realistic sounding piano music

2323
01:36:07,400 --> 01:36:12,239
after training the generator can

2324
01:36:09,719 --> 01:36:14,820
generate images like the ones shown here

2325
01:36:12,239 --> 01:36:16,980
and unfortunately the generated images

2326
01:36:14,820 --> 01:36:19,260
aren't as good as the original music

2327
01:36:16,980 --> 01:36:22,139
data set

2328
01:36:19,260 --> 01:36:24,420
so now images containing music of data

2329
01:36:22,139 --> 01:36:25,739
can be generated the next step is to

2330
01:36:24,420 --> 01:36:29,000
attend these into

2331
01:36:25,739 --> 01:36:29,000
sheet music and audio

2332
01:36:30,120 --> 01:36:35,820
so here's a short example of what the

2333
01:36:32,159 --> 01:36:38,520
neural network might generate

2334
01:36:35,820 --> 01:36:41,159
the horizontal axis represents the time

2335
01:36:38,520 --> 01:36:43,340
and the vertical axis represents the

2336
01:36:41,159 --> 01:36:43,340
pitch

2337
01:36:44,580 --> 01:36:49,199
so the image is split into multiple

2338
01:36:46,739 --> 01:36:51,900
sections and each section corresponds to

2339
01:36:49,199 --> 01:36:55,020
one part of music

2340
01:36:51,900 --> 01:36:55,020
[Music]

2341
01:36:55,219 --> 01:37:00,000
then taking out the first example first

2342
01:36:58,139 --> 01:37:02,159
section as the example

2343
01:37:00,000 --> 01:37:05,280
the noise can be encoded once again by

2344
01:37:02,159 --> 01:37:06,960
three numbers the offset which is the

2345
01:37:05,280 --> 01:37:08,580
number of Beats that we laughs when the

2346
01:37:06,960 --> 01:37:10,800
node is first played

2347
01:37:08,580 --> 01:37:12,120
the duration the number of Beats that's

2348
01:37:10,800 --> 01:37:14,520
held down for

2349
01:37:12,120 --> 01:37:17,340
and the pitch which is corresponds to

2350
01:37:14,520 --> 01:37:19,380
the key on the piano

2351
01:37:17,340 --> 01:37:21,780
so in this example you can see that some

2352
01:37:19,380 --> 01:37:24,179
of the notes overlap and this makes the

2353
01:37:21,780 --> 01:37:27,120
process of turning into sheet music and

2354
01:37:24,179 --> 01:37:29,639
audio audio more complicated because it

2355
01:37:27,120 --> 01:37:30,900
means that if I put the notes into one

2356
01:37:29,639 --> 01:37:33,420
sequence

2357
01:37:30,900 --> 01:37:35,219
then only one that can be played at a

2358
01:37:33,420 --> 01:37:38,940
time when there was supposed to be

2359
01:37:35,219 --> 01:37:41,540
multiple notes playing at the same time

2360
01:37:38,940 --> 01:37:44,480
so instead I separate the notes into

2361
01:37:41,540 --> 01:37:47,219
multiple non-overlapping sequences

2362
01:37:44,480 --> 01:37:48,540
represented by the different colors and

2363
01:37:47,219 --> 01:37:50,940
you can see that in each of the

2364
01:37:48,540 --> 01:37:53,580
different sequences the notes do not

2365
01:37:50,940 --> 01:37:55,820
overlap and each sequence is called a

2366
01:37:53,580 --> 01:37:55,820
voice

2367
01:37:57,300 --> 01:38:02,880
so now the notes can be turned into midi

2368
01:38:00,719 --> 01:38:04,860
files for the audio and PDF photoshoot

2369
01:38:02,880 --> 01:38:06,960
music

2370
01:38:04,860 --> 01:38:09,780
so for the media files the notes are

2371
01:38:06,960 --> 01:38:12,120
written as objects let me see 21 no

2372
01:38:09,780 --> 01:38:13,739
objects which contains its pitch and

2373
01:38:12,120 --> 01:38:16,080
duration

2374
01:38:13,739 --> 01:38:20,179
then the music21 library uses these

2375
01:38:16,080 --> 01:38:20,179
notes to generate the BD file

2376
01:38:22,260 --> 01:38:28,500
for the sheet music the notes are

2377
01:38:24,600 --> 01:38:30,600
represented by these strings

2378
01:38:28,500 --> 01:38:33,260
and the number on the end is the is the

2379
01:38:30,600 --> 01:38:33,260
notes duration

2380
01:38:34,380 --> 01:38:39,000
and then the notes are written into

2381
01:38:36,260 --> 01:38:41,340
their own containers and this ensures

2382
01:38:39,000 --> 01:38:43,440
that the notes can overlap and that are

2383
01:38:41,340 --> 01:38:45,900
played at the right time

2384
01:38:43,440 --> 01:38:48,300
and also rest notes of

2385
01:38:45,900 --> 01:38:50,540
uh used to fill in the gaps between no

2386
01:38:48,300 --> 01:38:50,540
it's

2387
01:38:52,080 --> 01:38:56,300
a certain type piece of music looks like

2388
01:38:54,060 --> 01:38:56,300
this

2389
01:38:57,960 --> 01:39:03,179
then to turn these notes into sheet

2390
01:39:00,239 --> 01:39:04,980
music I use the appjat library the agile

2391
01:39:03,179 --> 01:39:07,440
Library wraps the Lily Pawn music

2392
01:39:04,980 --> 01:39:09,780
notation software so it essentially

2393
01:39:07,440 --> 01:39:12,179
passes these musical notes written as

2394
01:39:09,780 --> 01:39:13,560
strings into lillypones which generates

2395
01:39:12,179 --> 01:39:16,880
the sheet music

2396
01:39:13,560 --> 01:39:16,880
so I'll demonstrate again

2397
01:39:18,420 --> 01:39:22,159
I'll change the parameters this time

2398
01:39:27,730 --> 01:39:57,780
[Music]

2399
01:39:54,780 --> 01:39:57,780
foreign

2400
01:40:01,880 --> 01:40:05,900
music in Python thank you

2401
01:40:10,380 --> 01:40:15,380
amazing

2402
01:40:12,600 --> 01:40:15,380
now

2403
01:40:16,860 --> 01:40:23,159
that was not a generated python music

2404
01:40:20,520 --> 01:40:24,840
now there's the fun bit that I spring on

2405
01:40:23,159 --> 01:40:27,840
the students that I didn't think we were

2406
01:40:24,840 --> 01:40:30,480
going to have time for

2407
01:40:27,840 --> 01:40:33,300
we've actually finished with enough time

2408
01:40:30,480 --> 01:40:34,739
to ask questions I think this is the

2409
01:40:33,300 --> 01:40:36,360
first time

2410
01:40:34,739 --> 01:40:38,760
we've managed this we also have

2411
01:40:36,360 --> 01:40:40,380
fantastic mugs they don't get presents

2412
01:40:38,760 --> 01:40:43,040
until they're finished no no no no no no

2413
01:40:40,380 --> 01:40:45,600
no no no no all right here we go

2414
01:40:43,040 --> 01:40:47,340
students can you all come up

2415
01:40:45,600 --> 01:40:48,060
oh

2416
01:40:47,340 --> 01:40:51,620
um

2417
01:40:48,060 --> 01:40:54,659
audience think of some questions

2418
01:40:51,620 --> 01:40:57,300
I'm going to make them all run through

2419
01:40:54,659 --> 01:40:59,880
their name again so just in case you've

2420
01:40:57,300 --> 01:41:02,580
forgotten who did the amazing thing

2421
01:40:59,880 --> 01:41:04,500
um think of your questions here we go oh

2422
01:41:02,580 --> 01:41:06,300
they're even in vague order amazing

2423
01:41:04,500 --> 01:41:07,980
unfortunately the remote students can't

2424
01:41:06,300 --> 01:41:09,960
join us but here we go yeah you can hold

2425
01:41:07,980 --> 01:41:13,440
up yeah for those of you who have much

2426
01:41:09,960 --> 01:41:17,460
better uh eyesight than I do I'm Bianca

Thomas

2432
01:41:30,780 --> 01:41:36,560
is your pie charm for real in uh Comic

2433
01:41:34,260 --> 01:41:36,560
Sans

2434
01:41:37,860 --> 01:41:42,500
um I would say no it's in comic mono

2435
01:41:50,100 --> 01:41:55,080
okay everything up here

2436
01:41:52,860 --> 01:41:57,600
sorry to double up on Thomas do you have

2437
01:41:55,080 --> 01:41:59,100
a GitHub for your video thing because I

2438
01:41:57,600 --> 01:42:00,719
totally want that instead of my webcam

2439
01:41:59,100 --> 01:42:01,440
oh yeah

2440
01:42:00,719 --> 01:42:04,980
um

2441
01:42:01,440 --> 01:42:06,060
yeah car block from the screen oh if you

2442
01:42:04,980 --> 01:42:06,780
give me a second car pull up on the

2443
01:42:06,060 --> 01:42:08,520
screen

2444
01:42:06,780 --> 01:42:12,480
oh yeah I'll do that that'll be better

2445
01:42:08,520 --> 01:42:16,040
wait we we can you can put we'll put it

2446
01:42:12,480 --> 01:42:16,040
on the Discord perfect yeah

2447
01:42:17,600 --> 01:42:22,159
definitely no no definitely not yeah

2448
01:42:22,739 --> 01:42:26,400
it's about when are you going to publish

2449
01:42:24,960 --> 01:42:29,060
your website so that I can actually use

2450
01:42:26,400 --> 01:42:29,060
it please

2451
01:42:29,280 --> 01:42:32,360
who was this one too

2452
01:42:32,580 --> 01:42:38,760
um okay so it it is actually like

2453
01:42:36,060 --> 01:42:41,940
at the point where it works it didn't

2454
01:42:38,760 --> 01:42:44,040
work currently because of the Wi-Fi but

2455
01:42:41,940 --> 01:42:46,440
it does work so I would just need to put

2456
01:42:44,040 --> 01:42:49,380
it on an app store

2457
01:42:46,440 --> 01:42:53,159
please do yes

2458
01:42:49,380 --> 01:42:55,920
uh and when you do uh we will ping the

2459
01:42:53,159 --> 01:42:58,159
Discord and let you all know in the

2460
01:42:55,920 --> 01:42:58,159
future

2461
01:42:58,500 --> 01:43:01,860
um so this one's for Sam and Morgan and

2462
01:43:00,900 --> 01:43:02,600
Josh

2463
01:43:01,860 --> 01:43:07,560
um

2464
01:43:02,600 --> 01:43:09,600
have have you looked into it all the

2465
01:43:07,560 --> 01:43:13,260
um the movement and division related to

2466
01:43:09,600 --> 01:43:15,179
uneven terrain at all but just flat

2467
01:43:13,260 --> 01:43:17,639
surfaces is still like that's that's

2468
01:43:15,179 --> 01:43:21,500
very fair I just asked because that's a

2469
01:43:17,639 --> 01:43:21,500
good reason to have hips yes

2470
01:43:21,840 --> 01:43:27,000
yeah so I kind of touched briefly on it

2471
01:43:24,659 --> 01:43:29,340
um yeah so the vision system is kind of

2472
01:43:27,000 --> 01:43:30,719
important to be able to allow movement

2473
01:43:29,340 --> 01:43:32,940
like that

2474
01:43:30,719 --> 01:43:35,820
um yeah so you can get a proper view a

2475
01:43:32,940 --> 01:43:38,219
3D View and then be able to like do

2476
01:43:35,820 --> 01:43:40,679
individual leg movements in like to be

2477
01:43:38,219 --> 01:43:41,760
able to move it in the right way

2478
01:43:40,679 --> 01:43:44,219
um there's obviously a lot of thought

2479
01:43:41,760 --> 01:43:45,659
and constraints that go into that

2480
01:43:44,219 --> 01:43:47,280
um yeah

2481
01:43:45,659 --> 01:43:50,420
um yeah so it's a bit of a ways off but

2482
01:43:47,280 --> 01:43:50,420
we are planning to do that yeah

2483
01:43:52,080 --> 01:43:56,580
hello great presentations everyone

2484
01:43:55,020 --> 01:43:58,260
um I had questions for a lot of you and

2485
01:43:56,580 --> 01:43:59,520
I forgot them halfway through but I

2486
01:43:58,260 --> 01:44:00,719
remembered one of them and that was for

2487
01:43:59,520 --> 01:44:03,900
Sean

2488
01:44:00,719 --> 01:44:05,960
um that was great very theoretical

2489
01:44:03,900 --> 01:44:05,960
um

2490
01:44:07,619 --> 01:44:11,719
do you think you would have spent more

2491
01:44:09,780 --> 01:44:15,320
time writing the program than actually

2492
01:44:11,719 --> 01:44:15,320
submitting your uh

2493
01:44:15,780 --> 01:44:19,679
um

2494
01:44:17,639 --> 01:44:21,540
it's more of like the psychological

2495
01:44:19,679 --> 01:44:24,900
thing you know

2496
01:44:21,540 --> 01:44:26,219
because like on every period I'm filling

2497
01:44:24,900 --> 01:44:29,400
out this form it's like the same thing

2498
01:44:26,219 --> 01:44:31,679
over and over again and I'm just dying

2499
01:44:29,400 --> 01:44:33,780
you know but if you automate this it

2500
01:44:31,679 --> 01:44:35,460
feels like you're hacking the system and

2501
01:44:33,780 --> 01:44:38,520
yeah you just don't need to worry about

2502
01:44:35,460 --> 01:44:40,679
it anymore it's great

2503
01:44:38,520 --> 01:44:42,860
you learned valuable things along the

2504
01:44:40,679 --> 01:44:42,860
way

2505
01:44:43,199 --> 01:44:46,260
there's another question here I'm just

2506
01:44:44,699 --> 01:44:47,520
running

2507
01:44:46,260 --> 01:44:49,560
hi everyone

2508
01:44:47,520 --> 01:44:51,540
um it's like mostly for everyone but

2509
01:44:49,560 --> 01:44:53,340
like who's thinking of sticking with it

2510
01:44:51,540 --> 01:44:55,080
as their main sort of career path and

2511
01:44:53,340 --> 01:44:57,119
who's thinking now like anything but

2512
01:44:55,080 --> 01:45:00,600
right here is the main creator

2513
01:44:57,119 --> 01:45:02,520
we will not uh harass you after

2514
01:45:00,600 --> 01:45:05,100
we promise we'll only do it with love

2515
01:45:02,520 --> 01:45:07,380
it's okay yeah yeah I'm sticking

2516
01:45:05,100 --> 01:45:08,580
yeah

2517
01:45:07,380 --> 01:45:10,800
um I don't know I want to go into more

2518
01:45:08,580 --> 01:45:13,520
applications to engineering of software

2519
01:45:10,800 --> 01:45:13,520
itself yeah

2520
01:45:13,800 --> 01:45:19,320
yeah I want to do software engineering

2521
01:45:16,679 --> 01:45:21,360
yeah I'm going to do robotics

2522
01:45:19,320 --> 01:45:23,820
really computer science yeah

2523
01:45:21,360 --> 01:45:25,020
with a deep voice yeah I'm kind of

2524
01:45:23,820 --> 01:45:26,400
sticking I'm hopefully switching to

2525
01:45:25,020 --> 01:45:30,179
cyber security but still in the IT

2526
01:45:26,400 --> 01:45:32,600
industry sticky yes yes I want to do AI

2527
01:45:30,179 --> 01:45:32,600
research

2528
01:45:32,880 --> 01:45:35,840
I'm sticking

2529
01:45:38,820 --> 01:45:42,300
I really kind of hoped one of you is

2530
01:45:40,440 --> 01:45:45,659
gonna say actually I'm already pursuing

2531
01:45:42,300 --> 01:45:46,619
a career in ballet or something like

2532
01:45:45,659 --> 01:45:49,280
that

2533
01:45:46,619 --> 01:45:51,600
um we have we are very Pro

2534
01:45:49,280 --> 01:45:56,420
multi-disciplinary computer science and

2535
01:45:51,600 --> 01:45:56,420
stuff uh other questions

2536
01:45:56,820 --> 01:46:01,619
um I I was interested in um in Daniel's

2537
01:45:59,940 --> 01:46:05,580
work are you are you thinking of putting

2538
01:46:01,619 --> 01:46:08,100
your your neural network music up as a

2539
01:46:05,580 --> 01:46:10,580
new AI type of thing for the public

2540
01:46:08,100 --> 01:46:10,580
Maybe

2541
01:46:13,280 --> 01:46:18,060
so right now I don't feel good enough

2542
01:46:15,360 --> 01:46:19,440
but once I get it improved then I'll put

2543
01:46:18,060 --> 01:46:22,199
it up

2544
01:46:19,440 --> 01:46:25,440
there's some money to be made there

2545
01:46:22,199 --> 01:46:28,320
I I think maybe that should team up with

2546
01:46:25,440 --> 01:46:30,540
the recommendations and you can get a

2547
01:46:28,320 --> 01:46:33,540
recommended

2548
01:46:30,540 --> 01:46:33,540
collaboration

2549
01:46:34,340 --> 01:46:40,560
that loud um so Daniel listen to you too

2550
01:46:37,739 --> 01:46:42,659
um on that idea of

2551
01:46:40,560 --> 01:46:44,159
um continuing your project

2552
01:46:42,659 --> 01:46:45,600
um do you currently have a functionality

2553
01:46:44,159 --> 01:46:48,900
or could implement the functionality to

2554
01:46:45,600 --> 01:46:51,780
have your music be less randomized and

2555
01:46:48,900 --> 01:46:53,400
more thematically themed like

2556
01:46:51,780 --> 01:46:54,659
around particular things that you're

2557
01:46:53,400 --> 01:46:57,440
trying to achieve particular composers

2558
01:46:54,659 --> 01:46:57,440
all that kind of stuff

2559
01:46:58,679 --> 01:47:03,659
yeah

2560
01:47:01,380 --> 01:47:05,460
I'll say this mostly depends on the

2561
01:47:03,659 --> 01:47:08,100
neural network which right now I'm not

2562
01:47:05,460 --> 01:47:10,380
experienced enough with AI to implement

2563
01:47:08,100 --> 01:47:11,580
like to make it better right now so I

2564
01:47:10,380 --> 01:47:12,960
have to learn more about it first and

2565
01:47:11,580 --> 01:47:16,280
then improve it

2566
01:47:12,960 --> 01:47:16,280
it will take a long time

2567
01:47:16,739 --> 01:47:22,580
you'll have years it's all right okay

2568
01:47:19,739 --> 01:47:22,580
over here

2569
01:47:23,000 --> 01:47:26,880
