10
00:00:39,600 --> 00:00:43,060
Fil-fatt, dan kien it-tip ta 'spontanju
introduzzjoni għal CS50 tal-ġimgħa żero

11
00:00:43,060 --> 00:00:44,940
dan it-tnaqqis fil-passat 2013.

12
00:00:44,940 --> 00:00:47,730

20
00:01:05,940 --> 00:01:09,620
>> Issa, peress li allura naturalment, aħna kont qed
jirċievu pjuttost ftit emails, Facebook

21
00:01:09,620 --> 00:01:14,750
postijiet, u tweets titlob dawn l-istess
Lampi desk CS50 jintbagħtu nazzjonalment

22
00:01:14,750 --> 00:01:15,960
u internazzjonalment.

23
00:01:15,960 --> 00:01:17,100

>> Fil-fatt, jekk inti tfittex up hemm fuq
l-ixkaffa ta 'fuq, se tara erba' kotba.

30
00:01:31,590 --> 00:01:35,850
U jekk aħna ittejjeb, tkun taf tara li huwa
sett canonical ta 'xjenza tal-kompjuter

31
00:01:35,850 --> 00:01:38,030
kotba minn ħafna magħrufa
xjentist kompjuter magħrufa

32
00:01:38,030 --> 00:01:41,100
kif Donald Knuth li kiteb,
L-Art ta 'Programmar.

33
00:01:41,100 --> 00:01:44,870
Mela jekk inti stess kienu qed ifittxu li jibnu
ġbir tiegħek stess ta 'xjenza tal-kompjuter

34
00:01:44,870 --> 00:01:48,780
canon, imorru quddiem u tieħu
tħares lejn L-Art ta 'Programmar.

35
00:01:48,780 --> 00:01:52,580
>> Issa, sadanittant, jekk nieħdu ħarsa lejn
videos li xi wħud mill-klassi tiegħek

36
00:01:52,580 --> 00:01:56,680
ssottomettew, se naraw l-

40
00:02:01,940 --> 00:02:04,410
U r-raġuni nixtieq
il-lampa hija bażikament

41

lampa fil-livelli kollha u I really

42
00:02:06,910 --> 00:02:10,519
bżonn wieħed kif qed nagħmel [inaudible]
għal [inaudible] u dan kollu Jittieħed.

43
00:02:10,519 --> 00:02:14,400
U jien ma jkollhom desk
fanal jew xi ħaġa bħal dik.

44
00:02:14,400 --> 00:02:17,000

Iżda dan iż-żmien, Mauricio
iddeċieda li teħodha up a talja

49
00:02:27,230 --> 00:02:30,580
u fil-fatt jagħti tiegħu
lecture stess għall-zero ġimgħa.

50
00:02:30,580 --> 00:02:34,324

51
00:02:34,324 --> 00:02:37,090

għal dak li inti tista 'taħseb.

54
00:02:46,300 --> 00:02:50,120
Hekk illum, ħsibna aħna se ċippa
bogħod fil dan in-nuqqas ta 'familjarità,

Aħna ma xi fanal desk hawn.

60
00:03:05,280 --> 00:03:06,470
Aħna ma tistax tmur fuq.

61
00:03:06,470 --> 00:03:09,250
Hekk ser ikollok biex jintemm dan lab hawn.

62
00:03:09,250 --> 00:03:13,500
Dan mhux CS50.

63
00:03:13,500 --> 00:03:14,560
>> Fl-CS50 jmiss -

64

joħolqu għalina kanzunetta tiegħu stess.

67
00:03:24,800 --> 00:03:28,790
>> SID: Hi, jien Sid, u jien mill-Indja.

68
00:03:28,790 --> 00:03:32,980
Irrid fanal desk għaliex -
kif madwar I tpoġġi dan il-mod.

69
00:03:32,980 --> 00:03:38,348

70
00:03:38,348 --> 00:03:41,276

Hekk jien tagħmel dan
video biex turi li inti guys

74
00:04:02,320 --> 00:04:06,110
għaliex I jistħoqqilhom marka fanal desk ġdida.

75
00:04:06,110 --> 00:04:08,850
Għalhekk tmur bħal dan.

76
00:04:08,850 --> 00:04:13,190
I nikseb għajjat ​​fil kull lejl għal
ma jitfu d-dwal.

Wieħed imħabba.

87
00:04:35,846 --> 00:04:39,600
Jekk jien ma tikseb wieħed, I mhux se jibqgħu jeżistu.

88
00:04:39,600 --> 00:04:42,500
Allura jekk jogħġbok agħti me fanal desk.

89
00:04:42,500 --> 00:04:44,680

Nispera li bhalu.

94
00:04:59,177 --> 00:05:01,260
DAVID Malan: Issa lest I
jkun shamed fuq l-internet,

95
00:05:01,260 --> 00:05:04,880
huwa CS50 li l-introduzzjoni għall-
intrapriżi intellettwali tal-kompjuter

96
00:05:04,880 --> 00:05:06,710
xjenza u l-arti ta 'programmazzjoni.

97
00:05:06,710 --> 00:05:09,610
Iżda Professur Donald Knuth li
kotba, jekk inti tixtieq li Google

98
00:05:09,610 --> 00:05:13,280
u jsibu lilhom lilek innifsek, huma Il-
Art ta 'Programmar tal-kompjuter.

99
00:05:13,280 --> 00:05:17,090
>> Issa, inti tista 'tfakkar li CS50 reċentement
sehem f'dan, film 48 siegħa

100
00:05:17,090 --> 00:05:19,950
proġett wherein CS50 kellhom
biss 48 siegħa biex joħolqu

101
00:05:19,950 --> 00:05:22,580
film qasir bil-
ftit elementi meħtieġa.

102
00:05:22,580 --> 00:05:25,560
Issa, wieħed mill-xeni minn
li l-film kien dan wieħed hawn

103
00:05:25,560 --> 00:05:27,570
wherein Daven kien
iddisprat taħdem flimkien

104
00:05:27,570 --> 00:05:31,540
l-Xmara Charles qrib Harvard
tipprova biss jgħidu bonjour.

105
00:05:31,540 --> 00:05:34,710
Issa, dak li inti tista 'ma jkunu realizzati
hija li taħdem quddiem dawn iż-żewġ

106
00:05:34,710 --> 00:05:36,170
kienu fil-fatt tliet guys.

107
00:05:36,170 --> 00:05:38,460
Fil-fatt, isaffru hawn
huwa ftit mill team CS50 tal.

108
00:05:38,460 --> 00:05:42,600
U jekk aħna zoom, tkun taf tara Ian
jkollu l-camera, Patrick azjenda

00:05:42,600 --> 00:05:44,880
Ian, u Dan jidderieġi l-xena.

110
00:05:44,880 --> 00:05:48,330
>> Issa, fil-ġustizzja, jekk aħna zoom
out, inti ser tara Ramon CS50 stess

00:05:48,330 --> 00:05:50,490
Galvan li kien biss running.

112
00:05:50,490 --> 00:05:52,610
Issa, dak Ian kien
iż-żamma bil-kamera

113
00:05:52,610 --> 00:05:54,560
Kien dan l-apparat hawn
li twettaq xi ħaġa

114
00:05:54,560 --> 00:05:58,160
imsejħa istabbilizzazzjoni image li hija l-
teknoloġija li aħna kienu qed iżommu

115
00:05:58,160 --> 00:06:01,930
li tir matul ix-xmara hekk relattivament
stabbli minkejja li dawn guys kienu

116
00:06:01,930 --> 00:06:03,290
kollha timxi lura.

117
00:06:03,290 --> 00:06:06,852
Issa, inti tista 'taf ta' dan it-tip
ta 'teknoloġija mill-imgħoddi.

118
00:06:06,852 --> 00:06:08,810
Fil-fatt, jekk inti kiber
mal-ġiroskopji hekk imsejħa

119
00:06:08,810 --> 00:06:11,130
skutella, li ħares ftit
xi ħaġa bħal din, dan

120
00:06:11,130 --> 00:06:15,160
huwa mezz sempliċi ħafna li
essenzjalment spins fuq tliet assi

121
00:06:15,160 --> 00:06:18,310
sabiex ikollok xi ċereali
ġewwa ta 'dan skutella, fit-teorija,

122
00:06:18,310 --> 00:06:20,830
hija qatt ma għandu jaqa '
minħabba li l-manki dejjem se

123
00:06:20,830 --> 00:06:23,570
iżommu l-iskutella innifsu
f'pożizzjoni wieqfa.

124
00:06:23,570 --> 00:06:25,570
Issa, I reċentement kellhom
opportunità li jqattgħu ħin

125
00:06:25,570 --> 00:06:29,600
ma stess Dan Coffey CS50 tal, li marru
fid-dettal aktar tekniċi dwar kif

126
00:06:29,600 --> 00:06:34,040
istabbilizzazzjoni image aktar moderna taħdem.

127
00:06:34,040 --> 00:06:37,130
>> Hekk jien hawn ta CS50
stess Dan Coffey, jogging

128

tul il-Xmara Charles
fuq il-kampus Harvard.

129
00:06:39,330 --> 00:06:41,755
Issa jekk Dan kienu biss bl-użu
kamera li jisparaw dan,

130
00:06:41,755 --> 00:06:44,670
l-immaġni tkun pretty
dgħajfa, żgur li mhux stabbli.

131
00:06:44,670 --> 00:06:50,070
Hu permezz ta 'teknika msejħa immaġni
stabilizzazzjoni li għandu, wieħed jittama,

132
00:06:50,070 --> 00:06:51,806
tiġi stabbilizzata l-immaġini.

133
00:06:51,806 --> 00:06:54,200
Nistgħu rimja l-bqija ta 'dan ġewwa?

134
00:06:54,200 --> 00:06:57,530

135
00:06:57,530 --> 00:06:58,070
>> OK.

136
00:06:58,070 --> 00:06:59,030
Istabbilizzazzjoni immaġini.

137
00:06:59,030 --> 00:06:59,720
X'inhu dan?

138
00:06:59,720 --> 00:07:00,449
Kif taħdem?

139
00:07:00,449 --> 00:07:02,740
DAN COFFEY: Allura għal ħafna snin,
l-industrija tat-TV u l-film

140
00:07:02,740 --> 00:07:05,430
ġew tipprova tikseb aktar dinamika
shots bl-introduzzjoni moviment,

141
00:07:05,430 --> 00:07:07,304
imma hija sfida li
jżommhom stabbilizzat.

142
00:07:07,304 --> 00:07:10,780
Inti stajt tidher Il-West Wing forsi
fejn dawn jagħmlu l-mixja u jitkellmu shot?

143
00:07:10,780 --> 00:07:13,620
U bażikament dak li huma jużaw
għal dak huwa cam stabbli,

144
00:07:13,620 --> 00:07:15,640
li huwa tagħmir kbir li tilbes.

145
00:07:15,640 --> 00:07:19,854
Huwa vest ma driegħ li l-iżolati

bilanċi ma 'serje ta' piżijiet.

147
00:07:21,395 --> 00:07:23,103
Iżda tieħu verament
żmien twil biex jitwaqqaf

148
00:07:23,103 --> 00:07:25,000
u huwa kkumplikata ħafna
attwalment jużaw.

149
00:07:25,000 --> 00:07:28,130
>> Hemm żviluppi ġodda fis-software
li tista 'tuża fejn inti tista' tagħmel

aġġustamenti fil Mac jew PC li
kultant jaħdmu, xi kultant ma.

00:07:31,074 --> 00:07:33,240
Iżda wieħed mill-aħħar
iżviluppi fil-fatt dan.

152
00:07:33,240 --> 00:07:34,720
Dan huwa l-M10 movi.

153
00:07:34,720 --> 00:07:38,490
Huwa biċċa verament pulita ta 'tagħmir
mill-ħbieb tagħna fil Systems Freefly.

154
00:07:38,490 --> 00:07:41,491
U bażikament, hija tuża serje ta '
gimbal assi biex jistabbilizzaw kamera tiegħek.

155
00:07:41,491 --> 00:07:42,698
DAVID Malan: X'hemm a gimbal?

156
00:07:42,698 --> 00:07:46,380
DAN COFFEY: Allura gimbal huwa sett ta '
ċrieki li kull spins fuq l-assi tagħha stess

157
00:07:46,380 --> 00:07:49,970
u bażikament iżolati f'kull direzzjoni,
jew il-x, y, jew il-z.

158
00:07:49,970 --> 00:07:52,420
U verament biss jagħmilha
ħafna bla xkiel u fluwidu.

159
00:07:52,420 --> 00:07:55,850
Allura dan M10 huwa gimbal kbir
u għandu tliet assi fuqha -

160
00:07:55,850 --> 00:08:00,420
wieħed hawn għall-tilt, huwa ltqajna wieħed
id-dahar għall-roll, u wieħed up top

161
00:08:00,420 --> 00:08:01,110
għall-pan.

162
00:08:01,110 --> 00:08:03,490
And I jistgħu attwalment nuruk jekk inti
trid tara kif dawn attwalment jaħdmu.

163
00:08:03,490 --> 00:08:03,760
>> DAVID Malan: Yeah, żgur.

164
00:08:03,760 --> 00:08:05,110
>> DAN COFFEY: Mela jekk inti
tfittex hawn fil-software,

165
00:08:05,110 --> 00:08:06,680
dan huwa Freefly Konfiguratur tagħhom.

166
00:08:06,680 --> 00:08:09,680
U huwa bażikament outputting
informazzjoni djanjostika dritt issa.

167
00:08:09,680 --> 00:08:12,214
Imma inti tara għandna tilt bil-mutur,
roll bil-mutur, bil-mutur u pan.

168
00:08:12,214 --> 00:08:14,130
U kif I attwalment pan
il-camera, int ser

169
00:08:14,130 --> 00:08:15,910
biex tara l-linji blu
jibdew imorru u 'l isfel.

170
00:08:15,910 --> 00:08:16,576
>> DAVID Malan: OK.

171
00:08:16,576 --> 00:08:17,775
Allura li tirrappreżenta l -

172
00:08:17,775 --> 00:08:20,340
>> DAN COFFEY: Huwa l-reżistenza
tal-mutur timbotta lura

173
00:08:20,340 --> 00:08:22,570
kontra me minħabba l-M10
dejjem trid li jiġu lura

174
00:08:22,570 --> 00:08:23,370
għall-mistrieħ fl-istess pożizzjoni.

175
00:08:23,370 --> 00:08:23,600
>> DAVID Malan: OK.

176
00:08:23,600 --> 00:08:25,850
Allura l-taller, l-inqas il-
bar, l-aktar reżistenza.

177
00:08:25,850 --> 00:08:29,350
DAN COFFEY: Yeah, l-intensità aktar
li l-mutur li jużaw għall-ġlieda kontra me.

178
00:08:29,350 --> 00:08:32,219
Jekk I tilt, tista 'tara l-
linja ħamra tagħmel l-istess ħaġa.

179
00:08:32,219 --> 00:08:32,844
U mbagħad roll -

180
00:08:32,844 --> 00:08:34,120
>> DAVID Malan: Il-linja l-ħadra u 'l isfel.

181
00:08:34,120 --> 00:08:36,600
>> DAN COFFEY: Allura dawn huma t-tliet
assi aħna qed istabbilizzar kontra.

182
00:08:36,600 --> 00:08:38,690
U għalhekk dan mhux normalment kif
inti topera, right?

183
00:08:38,690 --> 00:08:40,289
Hekk jekk I attwalment pick
dan up - u hawn,

184
00:08:40,289 --> 00:08:41,260
għaliex ma inti fil-fatt tistrieħ fuq dan.

185
00:08:41,260 --> 00:08:42,690
>> DAVID Malan: Yeah, żgur.

186
00:08:42,690 --> 00:08:43,429
Grazzi.

187
00:08:43,429 --> 00:08:45,410
>> DAN COFFEY: U issa
tista 'tara kif ftit

188
00:08:45,410 --> 00:08:47,740
il-camera jiċċaqlaq meta inti hit-tarf.

189
00:08:47,740 --> 00:08:49,987
It-tieqa, jekk inti se,
jibda pan miegħek.

190
00:08:49,987 --> 00:08:51,820
Li attwalment stabbiliti
l-software kif ukoll.

191
00:08:51,820 --> 00:08:52,210
>> DAVID Malan: nara.

192
00:08:52,210 --> 00:08:53,520
>> DAN COFFEY: Iżda hemm
fattur ieħor verament pulita.

193
00:08:53,520 --> 00:08:56,830
Jekk inti fil-aktar kumplikata
rimja, inti tista 'ddawar fuq dan il-bogħod,

194
00:08:56,830 --> 00:09:00,590
jkollhom it-tieni operatur camera
fil-fatt jagħmlu l-kontroll mrammel nitty.

195
00:09:00,590 --> 00:09:02,660
So I issa jistgħu pan, flex dan il-kontroll.

196
00:09:02,660 --> 00:09:05,270
I tista 'tilt u I jistgħu attwalment roll.

197
00:09:05,270 --> 00:09:09,160
Allura f'dan il-set-up, inti fil-fatt
tkun dik jiċċaqalqu l-camera fiżikament

198
00:09:09,160 --> 00:09:11,160
u jien jgħaqqdu
trasmettitur video wireless

199
00:09:11,160 --> 00:09:13,900
mal-kamera, poġġi
riċevitur hawn fuq monitor,

200
00:09:13,900 --> 00:09:17,740
u mbagħad I jistgħu attwalment, biss bħal
video game, jopera l-camera għalik.

201
00:09:17,740 --> 00:09:18,896
>> DAVID Malan: Nizza.

202
00:09:18,896 --> 00:09:20,720
>> DAN COFFEY: So I ser poġġih
lura fil-modalità operatur wieħed,

203
00:09:20,720 --> 00:09:22,810
imma int tista 'tikseb sens ta'
kif bla xkiel fil-fatt hu.

204
00:09:22,810 --> 00:09:24,230
>> DAVID Malan: Yeah, no, assolutament.

205
00:09:24,230 --> 00:09:26,290
U għandi idea.

206
00:09:26,290 --> 00:09:27,107
Tixtieq li ssegwi lili?

207
00:09:27,107 --> 00:09:27,815
DAN COFFEY: Sure.

208
00:09:27,815 --> 00:09:29,770
DAVID Malan: OK.

209
00:09:29,770 --> 00:09:33,280
Allura aħna qed hawn fil-kamra tal-banju li jittestjaw
xi istabbilizzazzjoni immaġini attwali

210
00:09:33,280 --> 00:09:36,000
quddiem, ukoll, il-
biss mera għandna.

211
00:09:36,000 --> 00:09:39,310
U ħsibt li d jkun interessanti li
tara biss kemm l-camera jiċċaqlaq meta

212
00:09:39,310 --> 00:09:42,055
I attwalment jimxu armi tiegħi
up, down, xellug u lemin.

213
00:09:42,055 --> 00:09:43,930
DAN COFFEY: Mela ejja
tara l-pan, tilt, roll.

214
00:09:43,930 --> 00:09:44,888
DAVID Malan: Kull dritt.

215
00:09:44,888 --> 00:09:46,136
Here we go.

216
00:09:46,136 --> 00:09:47,959
Ninsab verament jmexxuh.

217
00:09:47,959 --> 00:09:50,250
DAN COFFEY: So I jaraw ftit
bit-moviment, iżda I mean,

218
00:09:50,250 --> 00:09:52,300
int qatt ma tkun topera
huwa simili li jew.

219
00:09:52,300 --> 00:09:54,710
>> DAVID Malan: Le, żgur li le.

220

Aħna ser jagħmlu test fejn inti
fil-fatt imorru l-taraġ

224
00:10:02,900 --> 00:10:04,620
u I inti se twassal ma '
il-movi stabbilizzat,

Aħna bażikament jibnu
robots li tilgħab futbol.

290
00:13:10,294 --> 00:13:13,210
Radhika Nagpal: Allura l-isfida ta '
il-kompetizzjoni Robocup - u huwa

291
00:13:13,210 --> 00:13:16,510
f'kompetizzjoni internazzjonali li
kienet bdiet minn nies fl-Istati Uniti

292
00:13:16,510 --> 00:13:22,760
u l-Ġappun fil-fatt - huwa li jinħoloq tim
ta 'robots li jistgħu jilagħbu u possibbilment

293
00:13:22,760 --> 00:13:25,077
tirbaħ kontra d-dinja

KATE DONAHUE: Hemm timijiet
minn madwar id-dinja.

295
00:13:27,410 --> 00:13:29,910
U għaliex aħna qed jinfirxu s'issa
out, huwa verament diffiċli għalina

296
00:13:29,910 --> 00:13:31,800
biex jiksbu biex jittestjaw il-robots
kontra xulxin.

297
00:13:31,800 --> 00:13:34,560
Allura huwa bażikament biss tip
simili ta 'logħba futbol.

298
00:13:34,560 --> 00:13:37,550
Se jkun hemm xi round robin
logħob u mbagħad kompetizzjoni finali.

299
00:13:37,550 --> 00:13:40,290
U huwa ċans biex tara
kif robots tagħna munzell up

300
00:13:40,290 --> 00:13:42,740
kontra l-oħrajn u ideat biss kambju.

301

ma tistax tagħmel dan persuna anzjana tista ',

304
00:13:54,040 --> 00:13:56,310

li jmorru wara l-ballun
li jkun stabbilit għal xi sparatura.

307
00:14:00,030 --> 00:14:02,155
Imma dak li inti verament ikollhom
li tgħid il-kompjuter biex jagħmlu

308
00:14:02,155 --> 00:14:07,474
hu li ssib il-vector bejn il-ballun u
l-għan u jmorru hemm, nieqes il-kumpens.

309
00:14:07,474 --> 00:14:10,640

iżda aħna verament bżonn li jikkoordinaw.

313
00:14:16,080 --> 00:14:20,720
Hija sfida kbira u huwa kbir
meta aħna kollha jaħdmu fuq xi ħaġa flimkien.

314
00:14:20,720 --> 00:14:22,560
Allura aħna ser tinbena l-
parti mekkanika ta 'dan,

315
00:14:22,560 --> 00:14:25,484
u allura l-inġiniera elettriku
se tagħmel l-bordijiet ta 'ċirkuwiti,

316
00:14:25,484 --> 00:14:28,150
u l-poplu tax-xjenza tal-kompjuter
se għamlu simulazzjonijiet tagħhom

317
00:14:28,150 --> 00:14:30,850
u mbagħad jippruvaw u figura kif
jistgħu jgħaqqdu dan u tagħmel
