10
00:04:21,140 --> 00:04:23,140
>> We had some good times.

11
00:04:23,140 --> 00:04:28,760
This is the start of Week 11 and the end of CS50. [This was CS50.]

12
00:04:28,760 --> 00:04:31,760
Several weeks ago, we began the course with this mantra--

13
00:04:31,760 --> 00:04:34,760
What ultimately matters in this course is not so much where you end up relative to your

14
00:04:34,760 --> 00:04:39,500
classmates but where you, in Week 11, end up relative to yourself in Week 0.

15
00:04:39,500 --> 00:04:43,070
And this really is something that we've emphasized and do believe in as a course.

16
00:04:43,070 --> 00:04:48,160
I bring this up now--particularly with Quiz 1 just behind us--

17
00:04:48,160 --> 00:04:52,390
to reassure and really to bring perhaps some closing comfort

18
00:04:52,390 --> 00:04:56,960
that 1, Quiz 1 may have been a little long, (sound of laughter)

19
00:04:56,960 --> 00:05:01,280
but 2--what's really been interesting in teaching this course--

20
00:05:01,280 --> 00:05:05,170
the whole team and I for the past several years--is really the changing demographics.

21
00:05:05,170 --> 00:05:07,880
For the past several years it's definitely been the case

22
00:05:07,880 --> 00:05:11,150
that we've seen numbers like this--where 75-plus percent of your classmates

23
00:05:11,150 --> 00:05:16,450
have no prior CS experience, no APCS, no honor CS, no CS whatsoever;

24
00:05:16,450 --> 00:05:19,580
and a relative minority actually end up having significant experience,

25
00:05:19,580 --> 00:05:22,050
and those--we typically dub those more comfortable.

26
00:05:22,050 --> 00:05:26,250
But what's been interesting is to see these demographics changing since 2008.

27
00:05:26,250 --> 00:05:30,000
In 2008--the green represents less, the red represents more, 

28
00:05:30,000 --> 00:05:31,910
and the yellow represents somewhere in between--

29
00:05:31,910 --> 00:05:35,450
and suffice it to say, the green demographic has been growing.

30
00:05:35,450 --> 00:05:37,980
As a percentage we have as many more comfortable students as ever,

31
00:05:37,980 --> 00:05:41,810
but what's been interesting over the years is building out a support structure

32
00:05:41,810 --> 00:05:46,000
in place that can handle all the more effectively those of you--

33
00:05:46,000 --> 00:05:48,000
and this is many of you now--

34
00:05:48,000 --> 00:05:50,000
who are feeling particularly among those less comfortable

35
00:05:50,000 --> 00:05:52,000
in that big, green box there.

36
00:05:52,000 --> 00:05:55,000
>> So, realize that we're well aware of statistics, well aware of data. 

37
00:05:55,000 --> 00:05:59,220
It's absolutely the case that those more comfortable tend to perform higher--

38
00:05:59,220 --> 00:06:02,180
more percentage points higher than those less comfortable,

39
00:06:02,180 --> 00:06:05,650
but as promised in the syllabus, all of this is taken into account at semester's end.

40
00:06:05,650 --> 00:06:08,840
Indeed, the teaching fellows and I--besides just normalizing the raw scores

41
00:06:08,840 --> 00:06:12,500
based on section scores and TF's harshness and so forth--

42
00:06:12,500 --> 00:06:16,690
we also have a--really a conversation over email at the end of the semester

43
00:06:16,690 --> 00:06:21,350
where I will have 720 separate threads with the TF's about each and every one's students

44
00:06:21,350 --> 00:06:25,850
so we can really take into account that delta from Week 0 on through Week 11.

45
00:06:25,850 --> 00:06:29,160
So, rest assured that that is all indeed taken care of.

46
00:06:29,160 --> 00:06:33,430
With that said, comments like this don't go unnoticed.

47
00:06:33,430 --> 00:06:39,550
["I saw you get a 30% on the CS50 mid-term. The sadness is overwhelming."]

48
00:06:39,550 --> 00:06:44,850
Now, I realize that I Saw You Harvard isn't necessarily the best thermometer

49
00:06:44,850 --> 00:06:47,090
to take the temperature of a course, (laughter)

50
00:06:47,090 --> 00:06:52,900
but what I did want to say--is actually highlight one of the anonymous respondents to this

51
00:06:52,900 --> 00:06:57,590
who really got it spot-on using language that we don't really put in the syllabus--

52
00:06:57,590 --> 00:07:02,950
["...CS50's curve is super whack."] (laughter)

53
00:07:02,950 --> 00:07:07,520
But I can say that this course really is intended to get everyone through it successfully.

54
00:07:07,520 --> 00:07:11,630
And taking into account--perhaps moreso than a typical course--efforts,

55
00:07:11,630 --> 00:07:17,030
prior experience, and really changes and progression over the course of the semester.

56
00:07:17,030 --> 00:07:20,030
So, take to heart, if unofficially, this particular respondent's questions here.

57
00:07:20,030 --> 00:07:25,090
>> Another fun one, in that one of our teaching fellows used this to assuage the concerns

58
00:07:25,090 --> 00:07:29,180
of some of his friends. This appeared on Facebook just over a year ago.

59
00:07:29,180 --> 00:07:33,150
Some of you might have seen this online, but this is Lucas, one of our teaching fellows.

60
00:07:33,150 --> 00:07:36,680
He's against comfort food, but David Malan makes me feel otherwise.

61
00:07:36,680 --> 00:07:42,160
So that was a couple of days I think after Quiz 1 in Fall 2011, but if Lucas--

62
00:07:42,160 --> 00:07:44,980
you could stand up for just a moment as one of our teaching fellows now--

63
00:07:44,980 --> 00:07:50,500
(applause and cheers)

64
00:07:50,500 --> 00:07:52,650
It indeed worked out okay.

65
00:07:52,650 --> 00:07:56,030
Really, CS50 is meant to be this ongoing process for us.

66
00:07:56,030 --> 00:07:59,100
This is hopefully not the class you feel we phoned in in any way,

67
00:07:59,100 --> 00:08:01,430
and indeed it changes quite a bit every year.

68
00:08:01,430 --> 00:08:04,540
In fact, things that you see here on the board--CS50 Check, Discuss Gradebook,

69
00:08:04,540 --> 00:08:08,100
Run, Spaces, Submit--all of these were new tools that the team and others

70
00:08:08,100 --> 00:08:12,360
developed over the past several months in order to make Fall 2012

71
00:08:12,360 --> 00:08:15,800
all the more different and all the more of an experience for students,

72
00:08:15,800 --> 00:08:18,770
and we certainly realize that these things remain imperfect,

73
00:08:18,770 --> 00:08:22,100
but realize you've been as much a part of this experience and this experiment

74
00:08:22,100 --> 00:08:25,680
as we have in creating some of these tools and trying to learn from behavioral patterns

75
00:08:25,680 --> 00:08:29,000
just what works well and doesn't work well in a classroom.

76
00:08:29,000 --> 00:08:31,940
>> Indeed, this year we hypothesized that Annenberg office hours 

77
00:08:31,940 --> 00:08:33,940
would be better than last year.

78
00:08:33,940 --> 00:08:37,570
And so, the long history here in just a second is that for 20-plus years

79
00:08:37,570 --> 00:08:40,610
office hours and CS50 were held in the basement of the Science Center--

80
00:08:40,610 --> 00:08:44,179
a wonderfully-depressing, cubicle-like environment with fluorescent lighting.

81
00:08:44,179 --> 00:08:46,800
Back in the day, we would post a piece of paper on the wall.

82
00:08:46,800 --> 00:08:49,470
You'd come in, you'd have a question; you'd write your name physically on the wall,

83
00:08:49,470 --> 00:08:53,490
and then the TF's and I would walk around, crossing off names and then moving on

84
00:08:53,490 --> 00:08:55,490
to the next student.

85
00:08:55,490 --> 00:08:57,490
Well, that evolved over time into a white board.

86
00:08:57,490 --> 00:08:59,650
But last year, we then tried to reboot office hours altogether,

87
00:08:59,650 --> 00:09:03,370
and we've relocated to the houses--Leverett, Pforzheimer, Quincy and Lowell House--

88
00:09:03,370 --> 00:09:06,400
on different nights, and it actually worked out wonderfully well.

89
00:09:06,400 --> 00:09:08,950
I think it actually was one of the defining characteristics of last year

90
00:09:08,950 --> 00:09:13,380
for many of the students and staff, but we also kind of pushed out all of the residents

91
00:09:13,380 --> 00:09:15,910
one night a week from all of the various houses.

92
00:09:15,910 --> 00:09:18,630
Suffice it to say, when 150 CS50 students show up

93
00:09:18,630 --> 00:09:21,330
there's not much brain-break food or chairs left in the rooms.

94
00:09:21,330 --> 00:09:23,800
So, we thought moving to Annenberg would be a net positive,

95
00:09:23,800 --> 00:09:26,300
and it had its pluses, but it also had its minuses.

96
00:09:26,300 --> 00:09:29,580
Frankly, I don't love personally the vibe that we had in Annenberg this year,

97
00:09:29,580 --> 00:09:33,090
so if you felt that way, too, realize that this again is very much a process

98
00:09:33,090 --> 00:09:36,640
for us, and we're talking with the houses perhaps about returning to them in some form.

99
00:09:36,640 --> 00:09:40,790
But, of course, the tension then is if we return to one house we'll overwhelm it.

100
00:09:40,790 --> 00:09:43,040
So we could move to 2 separate houses in parallel.

101
00:09:43,040 --> 00:09:45,500
The catch there--we'd have half as much staff in each room,

102
00:09:45,500 --> 00:09:49,700
and we worry that demand will then rise to meet the greater supply in chairs.

103
00:09:49,700 --> 00:09:52,500
These are the sorts of things we'll be thinking through and working through

104
00:09:52,500 --> 00:09:55,880
with all of the feedback you guys have provided--ad nauseum, I know--

105
00:09:55,880 --> 00:09:59,550
on the Problem Set surveys, which we read and take very much to heart.

106
00:09:59,550 --> 00:10:01,950
>> Sections, too. We rebooted this year.

107
00:10:01,950 --> 00:10:04,490
The fact that you guys did relatively more coding online--

108
00:10:04,490 --> 00:10:07,330
in Section using Run, or Spaces, or the chalkboard--

109
00:10:07,330 --> 00:10:11,100
and did those exercises as part of the Pset was something new.

110
00:10:11,100 --> 00:10:13,640
This, too, worked well and not so well in different aspects.

111
00:10:13,640 --> 00:10:16,640
So, realize again, your feedback--which there'll be one more round of it forthcoming

112
00:10:16,640 --> 00:10:20,820
with the final project submission--is really invaluable for making the course

113
00:10:20,820 --> 00:10:24,400
as best as we can for future generations.

114
00:10:24,400 --> 00:10:28,140
The Shorts, too, were something entirely new this year and driven in large part by

115
00:10:28,140 --> 00:10:33,310
our participation in edX--which by the way, we're now up to 120,000.

116
00:10:33,310 --> 00:10:36,860
So, this too has kept us busy and will keep us busy through the Spring,

117
00:10:36,860 --> 00:10:40,660
and we would love to engage as many of you as possible in the development of

118
00:10:40,660 --> 00:10:44,760
CS50X; and this means more videos, more content, more tools and the like;

119
00:10:44,760 --> 00:10:47,670
and we'll followup via email about those opportunities.

120
00:10:47,670 --> 00:10:52,460
>> Indeed, for 2013, we're looking at more applications for students to use--

121
00:10:52,460 --> 00:10:54,780
more integrated into the course.

122
00:10:54,780 --> 00:10:59,280
For instance, we envision for CS50 Check--integrating that into CS50 Run itself

123
00:10:59,280 --> 00:11:01,960
so that within the confines of your browser, in some future term,

124
00:11:01,960 --> 00:11:05,220
you'll be able to click a button and voila get immediate graphical feedback 

125
00:11:05,220 --> 00:11:10,670
on your Problem Sets--much like you saw mid-semester with the first version of CS50 Check.

126
00:11:10,670 --> 00:11:13,930
And we'll also be rethinking office hours and Sections.

127
00:11:13,930 --> 00:11:17,710
So, now if that weren't enough reassurance that this is an ongoing process--

128
00:11:17,710 --> 00:11:20,840
of which all of you guys have been part--this is a bit of a meme that's been going around

129
00:11:20,840 --> 00:11:23,300
over the past few days, but I just thought I'd share--

130
00:11:23,300 --> 00:11:27,230
lest CS50 or some other course be stressing you out just a little bit,

131
00:11:27,230 --> 00:11:31,070
if you go to CS50.net/kittens, this actually has some DVR--

132
00:11:31,070 --> 00:11:35,520
there's no kittens there actually yet, so here we scroll back in time--

133
00:11:35,520 --> 00:11:37,520
let's go a little farther back--

134
00:11:37,520 --> 00:11:41,570
Oh, come on, get on camera--that's a big cat. Let's find the kittens. (laughter)

135
00:11:41,570 --> 00:11:53,590
There we go! You can just watch this all day long if you're feeling stressed. (laughter)

136
00:11:53,590 --> 00:11:55,540
>> Allow me to introduce 2 of my colleagues--

137
00:11:55,540 --> 00:12:00,170
Alyssa and Joy--for a moment up here. Come on up, guys.

138
00:12:00,170 --> 00:12:08,220
(applause and cheers)

139
00:12:08,220 --> 00:12:11,750
[Alyssa] Hi, my name is Alyssa. [Joy] And I'm Joy.

140
00:12:11,750 --> 00:12:14,500
[Alyssa] We're both sophomores in Quincy House studying Computer Science.

141
00:12:14,500 --> 00:12:18,410
[Joy] And we're also TF's for CS50.

142
00:12:18,410 --> 00:12:22,700
We actually held a seminar called ICT for DE Technology For Good.

143
00:12:22,700 --> 00:12:24,700
[Alyssa] We're starting a group on campus called Developers 4 Development--

144
00:12:24,700 --> 00:12:26,700
[Is your code ready to say hello to the world?] [git.to/hd4d] [HarvardD4D@gmail.com]

145
00:12:26,700 --> 00:12:31,150
and it aims to empower you to apply your new-found CS50 skills 

146
00:12:31,150 --> 00:12:33,870
to make an impact on the world.

147
00:12:33,870 --> 00:12:36,990
[Joy] So, we're going to bring in a lot of speakers from different fields--like global health,

148
00:12:36,990 --> 00:12:40,470
education and environment--to be able to connect you with opportunities

149
00:12:40,470 --> 00:12:44,000
to contribute to existing projects.

150
00:12:44,000 --> 00:12:46,960
[Alyssa] And we want to create a space for you guys to develop your own ideals as well.

151
00:12:46,960 --> 00:12:54,180
[Joy] So, if you're interested just check us out at git.to/hd4d in order to sign up

152
00:12:54,180 --> 00:12:58,950
for the email list and stay up-to-date with a lot of different events and opportunities.

153
00:12:58,950 --> 00:13:00,950
[Alyssa] Thank you! [Joy] Thanks!

154
00:13:00,950 --> 00:13:06,750
(applause and cheers)

155
00:13:06,750 --> 00:13:09,770
>> [David] We'll post the slides so that you have access to this URL after.

156
00:13:09,770 --> 00:13:12,490
What today's really about is not only wrapping up the course

157
00:13:12,490 --> 00:13:16,630
but also saying a few 'thank yous' which I thought we'd do up front since--even though

158
00:13:16,630 --> 00:13:20,060
it's you and the teaching fellows typically in the classroom environment--

159
00:13:20,060 --> 00:13:23,350
realize there's such a big team that goes--that works behind the scenes 

160
00:13:23,350 --> 00:13:26,440
including behind the cameras, behind the lights here in the lecture hall,

161
00:13:26,440 --> 00:13:29,720
as well as elsewhere on campus, and we wanted to thank not only them collectively--

162
00:13:29,720 --> 00:13:33,360
as we'll do so individually after the fact today--

163
00:13:33,360 --> 00:13:37,040
but also a few such folks who have really been integral to the course

164
00:13:37,040 --> 00:13:39,450
and have been perhaps among the most visible to you guys.

165
00:13:39,450 --> 00:13:43,630
The first one of which is Nate Hardison who we brought over from Stanford University 

166
00:13:43,630 --> 00:13:48,370
to join us this year as Preceptor, and if Nate, you would like to come on up to say hello

167
00:13:48,370 --> 00:14:02,560
one last time this term. (cheers and applause)

168
00:14:02,560 --> 00:14:07,370
>> [Nate] Well, hello! Here you guys are at the end of a long course.

169
00:14:07,370 --> 00:14:12,200
You guys have done a ton of stuff, so you all deserve a huge pat on the back

170
00:14:12,200 --> 00:14:15,690
and all sorts of candy and relax over Thanksgiving.

171
00:14:15,690 --> 00:14:18,360
I hope you guys have really enjoyed it so far.

172
00:14:18,360 --> 00:14:21,360
I just wanted to say thanks for letting me be a part of the course.

173
00:14:21,360 --> 00:14:26,330
It's been an awesome experience, and I hope you guys have enjoyed it as much as I have.

174
00:14:26,330 --> 00:14:33,770
Thanks! (cheers and applause)

175
00:14:33,770 --> 00:14:38,310
>> [David] As this 1 image here suggests, Nate really was integral particularly with the 

176
00:14:38,310 --> 00:14:42,670
development of CS50x which is still ongoing, and in fact when you have him here drawing 

177
00:14:42,670 --> 00:14:48,380
on the screen in binary notation, using an iPad--Nate filmed quite a few of the shorts that

178
00:14:48,380 --> 00:14:50,530
some of you might have engaged with over the course of this semester.

179
00:14:50,530 --> 00:14:54,110
And so, this material will live on not only this semester, but the vision for these shorts 

180
00:14:54,110 --> 00:14:57,800
and more is for it to carry over into future semesters, so that each year the course

181
00:14:57,800 --> 00:15:01,500
ideally gets a little bit better so that we can stand on our own shoulders--

182
00:15:01,500 --> 00:15:04,800
and those of Nate and his colleagues here--to make more and more content

183
00:15:04,800 --> 00:15:09,070
and more and more opportunities for students to get at the course's curriculum.

184
00:15:09,070 --> 00:15:13,320
Another very familiar face I wanted to bring up on stage to say a hello is this woman here--

185
00:15:13,320 --> 00:15:24,260
Zamyla Chan. (cheers and applause)

186
00:15:24,260 --> 00:15:29,470
>> Hi everyone! For one of the last times, I just wanted to say thank you to everyone

187
00:15:29,470 --> 00:15:32,160
for those of you who watch the Walkthrough, I hope that they helped.

188
00:15:32,160 --> 00:15:37,030
Also, congratulations to each and every one of you--regardless if you started out with

189
00:15:37,030 --> 00:15:41,820
no computer science experience whatsoever your first time coding or if you had a little bit--

190
00:15:41,820 --> 00:15:45,800
definitely I know that each and every one of you made so much progress,

191
00:15:45,800 --> 00:15:49,600
and so you should definitely feel proud of yourselves, and I hope that this also isn't

192
00:15:49,600 --> 00:15:52,520
your last time dabbling in CS50.

193
00:15:52,520 --> 00:15:56,800
There's definitely a lot of life after it whether you take courses or--

194
00:15:56,800 --> 00:15:59,150
you know, just continue on your own fiddling around.

195
00:15:59,150 --> 00:16:02,780
So, congratulations once again, and say hi when you have a chance.

196
00:16:02,780 --> 00:16:11,280
(cheers and applause)

197
00:16:11,280 --> 00:16:13,840
>> [David] Walkthroughs indeed seem to be very popular,

198
00:16:13,840 --> 00:16:17,560
and this is something that we're so glad that Zamyla agreed to take on this year.

199
00:16:17,560 --> 00:16:22,090
Indeed, she volunteered for the role and has been a wonderfully suited in that position

200
00:16:22,090 --> 00:16:26,770
and will live on on the Internet for quite a bit of time now.

201
00:16:26,770 --> 00:16:31,920
One more fellow is one of the fellows you've seen more recently.

202
00:16:31,920 --> 00:16:33,920
He dresses differently these days.

203
00:16:33,920 --> 00:16:36,670
He's been in a sweatshirt ever since this photo was taken.

204
00:16:36,670 --> 00:16:42,320
But Tommy MacWilliam started at CS50 as a TF years ago, 

205
00:16:42,320 --> 00:16:46,650
and this was our staff orientation get-together a couple of years back.

206
00:16:46,650 --> 00:16:50,300
And I swear to God, he looked that uncomfortable the entire event--

207
00:16:50,300 --> 00:16:55,260
to the extent that I actually dropped him a note afterwards asking him if there were

208
00:16:55,260 --> 00:16:58,850
people on staff that he knew or if we could introduce him to some people

209
00:16:58,850 --> 00:17:02,690
because we--on paper he was this amazing TF and this candidate we had hired,

210
00:17:02,690 --> 00:17:09,829
and I was genuinely worried that he was going to quit out of awkwardness. (laughter)

211
00:17:09,829 --> 00:17:12,760
But he didn't, and so Tommy if you'd like to come and say hello as well.

212
00:17:12,760 --> 00:17:19,730
(cheers and applause)

213
00:17:19,730 --> 00:17:22,690
>> [Tommy] Hi there! That email that he sent was really more along the lines of,

214
00:17:22,690 --> 00:17:26,300
"Hey Tommy, I'm really glad someone felt bad enough for you to come over to say hi.

215
00:17:26,300 --> 00:17:29,610
I hope that happens again in the future." (laughter)

216
00:17:29,610 --> 00:17:32,330
So really, I just want to congratulate everyone for getting through the course.

217
00:17:32,330 --> 00:17:34,740
It's so amazing to look back--if you had no coding skills, 

218
00:17:34,740 --> 00:17:36,980
now you've gone through the semester, you've made a scramble of friends.

219
00:17:36,980 --> 00:17:40,540
You've made an amazing website and an even more amazing final project to come.

220
00:17:40,540 --> 00:17:43,560
I'm really so grateful that I've been able to be a part of this.

221
00:17:43,560 --> 00:17:47,060
I still remember 3 years ago sitting right there--the 2nd row in that section--

222
00:17:47,060 --> 00:17:50,640
and in the same seats you are, just wanting to be a part of this course even more.

223
00:17:50,640 --> 00:17:56,970
I really encourage you to pursue CS further--even if it's not in the form of easy CS courses--

224
00:17:56,970 --> 00:18:00,500
but just pursuing more technical interests and things like that.

225
00:18:00,500 --> 00:18:03,250
I'd really encourage that since it's an amazing world to get into,

226
00:18:03,250 --> 00:18:06,360
and I'm really grateful that I was able to. So, good luck on your final projects!

227
00:18:06,360 --> 00:18:12,290
(applause)

228
00:18:12,290 --> 00:18:14,290
>> [David] One last one for now.

229
00:18:14,290 --> 00:18:20,990
An email I received on November 2, 2009--(laughing)

230
00:18:20,990 --> 00:18:24,890
He writes, is it possible to get an account on Cloud.CS50.net--

231
00:18:24,890 --> 00:18:27,020
the precursor to the CS50 appliance--

232
00:18:27,020 --> 00:18:29,020
if I'm not actually in CS50? 

233
00:18:29,020 --> 00:18:31,310
I wanted to take it this semester but was unable to fit it into my schedule.

234
00:18:31,310 --> 00:18:33,900
I'm a Freshman so could only take 4 classes,

235
00:18:33,900 --> 00:18:35,750
but I've been following along doing all of the Problem Sets,

236
00:18:35,750 --> 00:18:39,850
listening to all of the lectures--even coming to lectures when I could, etc.

237
00:18:39,850 --> 00:18:43,960
But now that you are on Cloud.CS50, I can't get the Problem Set framework problems

238
00:18:43,960 --> 00:18:45,960
and what not (sad face). 

239
00:18:45,960 --> 00:18:48,210
Last week I worked on the spellchecker with someone in the class

240
00:18:48,210 --> 00:18:53,340
but couldn't get the satisfaction of working late into the night perfecting it since I didn't

241
00:18:53,340 --> 00:18:57,310
exactly want to ask the person I was working with for her ID and password so I could

242
00:18:57,310 --> 00:19:03,450
use her account to program my own things while she slept. (laughter)

243
00:19:03,450 --> 00:19:05,450
Rob Bowden, everyone!

244
00:19:05,450 --> 00:19:16,250
(cheers and applause)

245
00:19:16,250 --> 00:19:20,890
>> [Rob] Thanks! Congratulations on making it here.

246
00:19:20,890 --> 00:19:25,090
I'm sure for a lot of you that's meant a lot of late Wednesday and Thursday nights.

247
00:19:25,090 --> 00:19:32,680
Also, it's meant a lot of late Thursdays for a lot of your TF's.

248
00:19:32,680 --> 00:19:35,960
Be sure to thank your TF for all the work they've put in.

249
00:19:35,960 --> 00:19:41,500
I feel like I'm asking my students to thank me now, but you don't have to. (laughter)

250
00:19:41,500 --> 00:19:48,480
I look forward to some amazing final projects, and I challenge you to go back to PSet 1

251
00:19:48,480 --> 00:19:53,100
and PSet 2 and look at the specs and the code that you actually wrote.

252
00:19:53,100 --> 00:19:57,870
Just think about it--this is so much easier now that I've gone 6 weeks since then.

253
00:19:57,870 --> 00:20:00,210
I'm sure you'll be impressed with how much you've learned.

254
00:20:00,210 --> 00:20:07,460
Thanks! (cheers and applause)

255
00:20:07,460 --> 00:20:10,680
>> [David] We thought we'd try something new for just a couple of minutes here.

256
00:20:10,680 --> 00:20:14,250
If Joseph and Tommy could join me up here on stage.

257
00:20:14,250 --> 00:20:17,610
Is anyone in this room comfortable enough coming up on stage--

258
00:20:17,610 --> 00:20:22,200
conditioned on your knowing your meme?

259
00:20:22,200 --> 00:20:26,880
Would someone who knows their memes like to join us up here on stage?

260
00:20:26,880 --> 00:20:31,800
I see a lot of this-- Yes, okay. There's one. Come on up.

261
00:20:31,800 --> 00:20:36,250
Two. Come on up. Oh, so many now.

262
00:20:36,250 --> 00:20:41,310
How about three here, and how about four. And five. Come on up.

263
00:20:41,310 --> 00:20:44,360
We have 5 stools for you here.

264
00:20:44,360 --> 00:20:47,430
This is a new game we're work-shopping here in CS50.

265
00:20:47,430 --> 00:20:50,660
If you guys would each like to take a stool.

266
00:20:50,660 --> 00:20:52,750
Tommy and Joseph are going to run the mikes here.

267
00:20:52,750 --> 00:20:55,380
I'm going to take care of the slides.

268
00:20:55,380 --> 00:20:59,730
In just a moment, we've got a Know Your Meme episode here 2012.

269
00:20:59,730 --> 00:21:03,600
So what you're about to see is a sequence of memes.

270
00:21:03,600 --> 00:21:07,560
But let me introduce again, Joseph and Tommy, for the particulars.

271
00:21:07,560 --> 00:21:10,730
Oh, hi Lucas. You're playing too? Okay. (laughing)

272
00:21:10,730 --> 00:21:12,730
Tommy and Joseph.

273
00:21:12,730 --> 00:21:16,760
>> [Tommy] All right. So, the goal of this game is we're going to flash up a meme

274
00:21:16,760 --> 00:21:19,090
on the screen, and there are 2 parts.

275
00:21:19,090 --> 00:21:22,470
First, you have to name what the meme is, so we're looking for the official name

276
00:21:22,470 --> 00:21:26,580
not--oh yeah, that funny thing with that funny guy--the official meme.

277
00:21:26,580 --> 00:21:30,160
And then, for a bonus point, you can either make your own--

278
00:21:30,160 --> 00:21:35,280
give your own caption to the meme--or give your best re-enactment. Make sense?

279
00:21:35,280 --> 00:21:41,330
Okay. The memes will be here, on the screen.

280
00:21:41,330 --> 00:21:43,050
[Joseph] Do you want to look for hands up in the air?

281
00:21:43,050 --> 00:21:45,960
[Tommy] You got hands?

282
00:21:45,960 --> 00:21:50,500
Okay, ready? So, here's our first meme.

283
00:21:50,500 --> 00:21:53,650
[Just used my last Pandora skip for the hour] [Next song is even worse]

284
00:21:53,650 --> 00:21:58,280
[Joseph] I saw your hand go up. I forget your name. I'm sorry.

285
00:21:58,280 --> 00:22:00,890
Vincent. Okay. Go.

286
00:22:00,890 --> 00:22:02,570
[Vincent] First Word Problems. >>[Joseph] That is correct. Okay.

287
00:22:02,570 --> 00:22:04,960
I'll give Vincent a point. (cheering)

288
00:22:04,960 --> 00:22:10,700
Actually, can we pass the mike around and speak into the mike so everyone can hear you.

289
00:22:10,700 --> 00:22:16,440
[David] Here, we'll give Vincent a stress ball. >>[Tommy] Vincent has just earned a stress ball.

290
00:22:16,440 --> 00:22:21,890
(cheering and applause)

291
00:22:21,890 --> 00:22:30,210
[Vincent] Walk from ye in dorms to Annebrook for breakfast. No hash--no the shredded hash--

292
00:22:30,210 --> 00:22:37,350
(laughter) [Tommy] Awesome! Okay. (cheers and applause)

293
00:22:37,350 --> 00:22:46,450
(crowd murmurs as board tips over)

294
00:22:46,450 --> 00:22:49,540
[Joseph] Okay. I got it. I got it guys. I got it.

295
00:22:49,540 --> 00:22:53,940
[David] You know, I think we'll leave that in the video. (laughter)

296
00:22:53,940 --> 00:22:56,260
>> [Joseph] All right. Who's next? >>[Tommy] All right. Next meme.

297
00:22:56,260 --> 00:22:58,710
[Makes fun of you for your job] [Has no job] (laughter)

298
00:22:58,710 --> 00:23:03,540
[Joseph] Vincent's hand went up first, but since you just answered the last one,

299
00:23:03,540 --> 00:23:05,540
I'll let RJ do this one.

300
00:23:05,540 --> 00:23:07,540
[RJ] Scumbag Steve?

301
00:23:07,540 --> 00:23:10,700
[Tommy] That is correct. (laughter and applause)

302
00:23:10,700 --> 00:23:26,920
[RJ] Has one job. Drops the chalkboard. (laughter and applause)

303
00:23:26,920 --> 00:23:30,270
(audience laughter)

304
00:23:30,270 --> 00:23:32,960
[Tommy] And we can stop there. RJ wins.

305
00:23:32,960 --> 00:23:34,960
All right. Next meme.

306
00:23:34,960 --> 00:23:36,960
[Not sure if N64 games were actually better or if just because I was 10]

307
00:23:36,960 --> 00:23:38,960
[Joseph] Lexie's hand went up.

308
00:23:38,960 --> 00:23:42,900
[Lexie] Futurama Fry. >>[Tommy] That is correct. (laughter)

309
00:23:42,900 --> 00:23:45,840
[Lexie] Oh, man. >>[Tommy] Your own take?

310
00:23:45,840 --> 00:23:54,700
[Lexie] My own take? Not sure if nervous or just always has red face. (laughter)

311
00:23:54,700 --> 00:24:01,830
Oh, that was really bad, guys. Sorry. I tried. Love you all. (cheers and laughter)

312
00:24:01,830 --> 00:24:04,120
[Tommy] All right. Our next meme.

313
00:24:04,120 --> 00:24:06,120
[Oh, you wear a Northface jacket?] [You must go on to many adventures]

314
00:24:06,120 --> 00:24:11,980

00:38:47,430 --> 00:38:51,430
entire evening in, and upon arrival, you will see this hallway here.

472
00:38:51,430 --> 00:38:55,750
Walking down it and up to the elevators, you'll then see someone like Kenny here

473
00:38:55,750 --> 00:39:00,740
greeting you with lots of balloons, at which point you'll see a very cleverly-worded sign

474
00:39:00,740 --> 00:39:04,730
made every year by the TF's in order to figure out what line you should get in.

475
00:39:04,730 --> 00:39:10,080
All right. (laughter and groans) Well, it's going to be there.

476
00:39:10,080 --> 00:39:13,230
Then you'll grab a name tag from one of the folks checking you in.

477
00:39:13,230 --> 00:39:17,260
You'll put it on, and around 9 p.m. you'll grab some candy and the like.

478
00:39:17,260 --> 00:39:20,190
You'll set up shop with your laptop and hundreds of your classmates.

479
00:39:20,190 --> 00:39:23,470
The TF's, CA's and I will be floating around doing our own thing--

480
00:39:23,470 --> 00:39:25,470
answering questions and the like.

481
00:39:25,470 --> 00:39:28,010
Shortly thereafter, some pizza will be served. This was last year's event here.

482
00:39:28,010 --> 00:39:31,610
Then we'll all get back to work writing some code.

483
00:39:31,610 --> 00:39:36,360
Then around 1 a.m., some Chinese food will be served, and you'll transition from this

484
00:39:36,360 --> 00:39:40,110
environment to one a little more like this, and about half of the table is actually cut off.

485
00:39:40,110 --> 00:39:44,140
That was catering from a local Chinese place last year.

486
00:39:44,140 --> 00:39:49,830
Then around 2 or 3 a.m. we'll get back to work, and from there transition to--

487
00:39:49,830 --> 00:39:52,830
if you're still awake--to IHOP.

488
00:39:52,830 --> 00:39:56,250
In fact, even if you're awake when you get on the shuttle, it doesn't always work 'til the end.

489
00:39:56,250 --> 00:39:59,930
This is not uncommon in the IHOP down the road.

490
00:39:59,930 --> 00:40:01,450
>> And then after this, of course, is the CS50 Fair which is an event for all students in the class.

492
00:40:05,000 --> 00:40:09,130
It's meant to be really the climax of the semester towards semester's end

493
00:40:09,130 --> 00:40:12,670
where you'll have an opportunity to descend stairs like these in northwest Science,

494
00:40:12,670 --> 00:40:14,670
just up the road.

495
00:40:14,670 --> 00:40:17,650
You'll be pelted with stress balls typically by the TF's dressed something like this.

496
00:40:17,650 --> 00:40:22,930
Upon arrival you'll head to a table where hundreds of faculty and students and staff

497
00:40:22,930 --> 00:40:27,090
from across campus will be joining you with balloons and with people glancing over your 

498
00:40:27,090 --> 00:40:35,220
screen looking at what you've done, with such cool things as recruiters situated in the back.

499
00:40:35,220 --> 00:40:39,270
We invite our friends from industry so that you can chat up folks about life after 50--

500
00:40:39,270 --> 00:40:42,150
whether it's an internship that's of interest, a full-time gig, or the like.

501
00:40:42,150 --> 00:40:45,880
This is a beginning list of this year's attendees who will be joining us.

502
00:40:45,880 --> 00:40:50,390
Perhaps more compellingly, we also have a raffle each year whereby upon arrival

503
00:40:50,390 --> 00:40:55,480
for each student, you chat up--whether you're in the class or you're a friend of someone

504
00:40:55,480 --> 00:40:58,400
in the class--you'll be handed by a CS50 student a little sticker.

505
00:40:58,400 --> 00:41:01,750
The more stickers you accumulate from having these chats, the more opportunities you have

506
00:41:01,750 --> 00:41:03,750
to win fabulous prizes like these from last year.

So, that too helps break the ice so that if you don't want to be that awkward person that

510
00:41:09,750 --> 00:41:12,860
walks up to someone and starts chatting them up--now at least you have an excuse--

you want an Xbox.
