1
00:00:00,000 --> 00:00:11,664

2
00:00:11,664 --> 00:00:13,830
MICHAEL D. SMITH: Dan
wara nofsinhar Għandi l-pjaċir

3
00:00:13,830 --> 00:00:16,830
ta 'introduzzjoni Mark Zuckerberg,
li hija waħda ta 'kelliema mistiedna tagħna

4
00:00:16,830 --> 00:00:21,030
dan is-semestru li ġejjin u jitkellmu
ftit dwar ix-xjenza tal-kompjuter

5
00:00:21,030 --> 00:00:22,040
fid-dinja reali.

6
00:00:22,040 --> 00:00:25,350
Billi ħafna mill inti probabilment taf, bħala
inti guys kollha jagħmlu dan ħafna aktar

7
00:00:25,350 --> 00:00:30,090
minn I do, fundatur tal Facebook.com,
li huwa netwerking soċjali

8
00:00:30,090 --> 00:00:32,200
programm, tkun xi tkun tixtieq li hija sejħa.

9
00:00:32,200 --> 00:00:37,094
Użati fil aktar minn 2000 iskejjel madwar l-
nazzjon, u possibbilment id-dinja wisq.

10
00:00:37,094 --> 00:00:38,760
Huwa fid-dinja wisq, jew sempliċiment l-nazzjon?

11
00:00:38,760 --> 00:00:39,750
>> Zuckerberg Mark: [inaudible].

12
00:00:39,750 --> 00:00:40,740
>> MICHAEL D. SMITH: OK.

13
00:00:40,740 --> 00:00:45,007
Influwenza hekk tajjeb biex isir
xi affarijiet fix-xjenza tal-kompjuter.

14
00:00:45,007 --> 00:00:47,090
Hu għaddej biex tgħidilna xi
tal-isfond ta 'dan

15
00:00:47,090 --> 00:00:48,780
u dak li kien importanti u ibqa 'sejjer hekk.

16
00:00:48,780 --> 00:00:50,140
Allura jekk jogħġbok jissieħbu miegħi fl merħba.

17
00:00:50,140 --> 00:00:56,080

18
00:00:56,080 --> 00:00:57,360
>> Zuckerberg Mark: Yo.

19
00:00:57,360 --> 00:00:57,540
Kull dritt, berred.

20
00:00:57,540 --> 00:01:00,248
Dan huwa l-ewwel darba stajt qatt
kellhom ikollhom wieħed minn dawn l-affarijiet.

21
00:01:00,248 --> 00:01:02,818
Hekk jien biss se jagħtu
huwa verament malajr, it-tieni wieħed.

22
00:01:02,818 --> 00:01:14,270

23
00:01:14,270 --> 00:01:14,770
Kull dritt.

24
00:01:14,770 --> 00:01:16,264
Inti tista 'tisma?

25
00:01:16,264 --> 00:01:17,740
Dan huwa tajjeb?

26
00:01:17,740 --> 00:01:19,160
Huwa dan amplifikati fil-livelli kollha?

27
00:01:19,160 --> 00:01:19,797
>> UDJENZA: Yeah.

28
00:01:19,797 --> 00:01:20,922
Zuckerberg Mark: Kull dritt.

29
00:01:20,922 --> 00:01:21,979
Sweet.

30
00:01:21,979 --> 00:01:24,895
Dan huwa simili waħda mill-ewwel żminijiet
Stajt kien li lekċer fl Harvard.

31
00:01:24,895 --> 00:01:31,950

32
00:01:31,950 --> 00:01:35,480
I raden dak li probabbilment se tkun
aktar utli għalik guys hija jekk I biss

33
00:01:35,480 --> 00:01:39,104
tieħu miegħek permezz xi wħud mill-korsijiet
li ħadt fil-Harvard fejn I attwalment

34
00:01:39,104 --> 00:01:40,270
ma mur lecture kultant.

35
00:01:40,270 --> 00:01:42,230
I kien joking.

36
00:01:42,230 --> 00:01:44,120
U tip ta ', bħal, kif
deċiżjonijiet differenti

37
00:01:44,120 --> 00:01:46,711
li kelli biex jagħmlu meta kelli
jiċċaqalqu flimkien ma Facebook

38
00:01:46,711 --> 00:01:49,460
ltqajna affettwati minn Jittieħed differenti
li I kien tagħlim fil-klassijiet

39
00:01:49,460 --> 00:01:50,427
li I kienet qed tieħu.

40
00:01:50,427 --> 00:01:53,010
U jekk kollox imur skond il-
pjan, allura forsi xi wħud minnkom guys

41
00:01:53,010 --> 00:01:55,759
se joħorġu minn dan il-ħsieb
li t-teħid CS jew għalf inġinerija

42
00:01:55,759 --> 00:01:57,760
fil-Harvard huwa attwalment tip ta utli.

43
00:01:57,760 --> 00:02:00,640
Allura dak hu l-pjan logħba.

44
00:02:00,640 --> 00:02:02,670
>> Naħseb li dan huwa
jaw għal sagħtejn.

45
00:02:02,670 --> 00:02:04,670
M'hemm l-ebda mod jien ser
jitkellem għal sagħtejn.

46
00:02:04,670 --> 00:02:07,110
I probabilment jitkellmu bħal
20 minuta, jew 15-il minuta,

47
00:02:07,110 --> 00:02:08,750
u mbagħad I ser biss let
inti guys jistaqsu mistoqsijiet.

48
00:02:08,750 --> 00:02:10,958
Għaliex jien ċert li inti guys
Jittieħed aktar interessanti

49
00:02:10,958 --> 00:02:14,816
li jistaqsu lili minn I jistgħu jidħlu
bi biex jitkellmu dwar myself.

50
00:02:14,816 --> 00:02:16,760
>> So I raden I taf biss
tip ta 'tibda.

51
00:02:16,760 --> 00:02:19,810

52
00:02:19,810 --> 00:02:23,580
Meta I kien hawn, I
bdew jieħdu 121.

53
00:02:23,580 --> 00:02:26,297
I-fatt qatt ma ħa 50.

54
00:02:26,297 --> 00:02:28,130
Għandek gotten
il-Guy-oħra li kien

55
00:02:28,130 --> 00:02:31,190
tagħmel Facebook, Dustin
Moskovitz, li kien roommate tiegħi.

56
00:02:31,190 --> 00:02:34,792
Meta sirna beda s-sit kien
miktuba fil-PHP, li mhix xi ħaġa

57
00:02:34,792 --> 00:02:36,500
li inti mgħallma fl-
wieħed minn dawn il-klassijiet.

58
00:02:36,500 --> 00:02:38,960
Iżda fortunatament, jekk inti
jkollhom sfond tajba fis-C,

59
00:02:38,960 --> 00:02:42,790
l-sintassi hija simili ħafna, u
inti tista 'pick it up fil-jum jew tnejn.

60
00:02:42,790 --> 00:02:49,020
>> So I bdew bil-miktub is-sit
u imnedija fil-Harvard

61
00:02:49,020 --> 00:02:51,040
fi Frar 2004.

62
00:02:51,040 --> 00:02:52,750
So I raden kważi sentejn ilu issa.

63
00:02:52,750 --> 00:02:55,770
U fi żmien ftit ġimgħat, a
ftit eluf ta 'nies kienu ffirmaw up.

64
00:02:55,770 --> 00:02:57,686
U bdejna jkollna
xi emails minn nies

65
00:02:57,686 --> 00:03:00,800
fil-kulleġġi oħra titlob għalina
jnediha fl-iskejjel tagħhom.

66
00:03:00,800 --> 00:03:02,725
>> U I kien qed 161 fil-ħin.

67
00:03:02,725 --> 00:03:05,350
So I do not know jekk inti guys taf
l-reputazzjoni ta 'dak il-kors,

68
00:03:05,350 --> 00:03:07,662
iżda kienet tip ta 'heavy.

69
00:03:07,662 --> 00:03:10,370
Kien kors verament gost, imma
hija ma leave me ma 'ħafna ħin

70
00:03:10,370 --> 00:03:12,510
biex tagħmel xi ħaġa oħra ma Facebook.

71
00:03:12,510 --> 00:03:16,360
Allura roommate tiegħi Dustin, li I
raden kien biss lest CS50,

72
00:03:16,360 --> 00:03:18,370
kien simili, ħej, I jixtiequ jgħinu out.

73
00:03:18,370 --> 00:03:22,009
I trid tagħmel l-espansjoni u jgħinu
inti figura kif jagħmlu l-għalf.

74
00:03:22,009 --> 00:03:24,050
So I kien simili, tafu,
thats raġel pretty jibred,

75
00:03:24,050 --> 00:03:26,500
imma inti ma verament jafu xi
PHP jew xi ħaġa bħal dik.

76
00:03:26,500 --> 00:03:29,919
Allura li weekend huwa marru dar,
xtara l-ktieb Perl għall-manikini,

77
00:03:29,919 --> 00:03:31,960
daħal lura u kien simili,
alright, jien lesta li tmur.

78
00:03:31,960 --> 00:03:35,560
I kien bħal raġel, is-sit huwa miktub
fil-PHP, ma Perl, imma inti taf,

79
00:03:35,560 --> 00:03:36,270
thats jibred.

80
00:03:36,270 --> 00:03:41,800
>> Hekk hu qabad PHP fuq
ftit jiem għaliex, I

81
00:03:41,800 --> 00:03:44,090
wegħda li jekk għandek
sfond tajba fis-C, imbagħad

82
00:03:44,090 --> 00:03:46,230
PHP hija ħaġa sempliċi ħafna li pick up.

83
00:03:46,230 --> 00:03:49,390
U hu biss tip ta 'marru biex jaħdmu.

84
00:03:49,390 --> 00:03:53,120
So I mean, l-ewwel deċiżjoni kbira
li aħna verament kellhom jagħmlu

85
00:03:53,120 --> 00:03:57,140
kien kif tip ta '
jespandu l-arkitettura

86
00:03:57,140 --> 00:04:01,920
li jmorru mit-tip skola uniku stabbilit
li kellna meta kien biss fil-Harvard

87
00:04:01,920 --> 00:04:03,830
għal xi ħaġa li
appoġġjati iskejjel multipli.

88
00:04:03,830 --> 00:04:06,890
>> Għalhekk din kienet deċiżjoni li kellha
li għandhom isiru fuq mazz ta 'livelli,

89
00:04:06,890 --> 00:04:10,000
kemm fil-prodott u kif
ridna privatezza għax-xogħol,

90
00:04:10,000 --> 00:04:12,510
iżda naħseb li wieħed verament
deċiżjoni importanti li l-

91
00:04:12,510 --> 00:04:16,180
għen lilna skala pretty ukoll huwa kif
aħna iddeċieda li jiddistribwixxu l-data.

92
00:04:16,180 --> 00:04:21,680
>> So I do not know kemm ta 'kumplessità
għalf bħal big notazzjoni O inti guys

93
00:04:21,680 --> 00:04:23,620
f'din il-klassi.

94
00:04:23,620 --> 00:04:28,610
So I mean, wieħed mill-aktar kumplikata
komputazzjonijiet li nagħmlu fuq is-sit

95
00:04:28,610 --> 00:04:32,080
huwa l-komputazzjoni li tgħid kif
int konness ma nies.

96
00:04:32,080 --> 00:04:34,680
>> Għaliex jekk inti tista '
jimmaġina, thats maħżuna

97
00:04:34,680 --> 00:04:42,210
bħala tip ta 'serje ta' undirected -
mhuwiex peżati - so undirected,

98
00:04:42,210 --> 00:04:45,970
pari unweighted ta 'numri ID
ta 'nies fid-database.

99
00:04:45,970 --> 00:04:49,647
Imbagħad jekk inti tixtieq li insemmu
li huwa ħbieb ma 'xi ħadd,

100
00:04:49,647 --> 00:04:51,230
inti għandek tfittex fil-ħbieb tagħhom.

101
00:04:51,230 --> 00:04:51,730
Dritt?

102
00:04:51,730 --> 00:04:54,000
Allura dak forsi bħal 100 jew 200 ruħ.

103
00:04:54,000 --> 00:04:57,050
>> Iżda mbagħad jekk inti tixtieq figura
min huwa ħabib ta 'ħabib,

104
00:04:57,050 --> 00:04:59,800
jew dak l-eqreb rabta
hemm, imbagħad inti tip ta '

105
00:04:59,800 --> 00:05:03,440
għandek tfittex fil-100 jew 200
ħbieb ta 'kull wieħed minn dawk il-ħbieb.

106
00:05:03,440 --> 00:05:10,020
Biex dan isir f'kull livell hemm
fattur ieħor ta 'n immultiplikat n, fejn

107
00:05:10,020 --> 00:05:13,861
n huwa n-numru ta 'ħbieb
li kull wieħed mill-ħbieb tiegħek tkun.

108
00:05:13,861 --> 00:05:16,110
Allura tista 'tara li dan
tip ta 'isir b'mod esponenzjali

109
00:05:16,110 --> 00:05:20,076
diffiċli biex isolvu l-
iqsar passaġġ bejn in-nies.

110
00:05:20,076 --> 00:05:22,950
Mela jekk inti qed tfittex biss għal
ħabib ta 'ħabib, thats n kwadru.

111
00:05:22,950 --> 00:05:25,520
Jekk qed tfittex għal xi ħabib ta '
ħabib ta 'ħabib, thats n kubiku.

112
00:05:25,520 --> 00:05:27,311
U li xi ħaġa
li tradizzjonalment kienet

113
00:05:27,311 --> 00:05:31,590
pretty diffiċli għal lott tal-
siti predeċessur Facebook.

114
00:05:31,590 --> 00:05:34,210
U per eżempju, Friendster
kellhom problemi kbar ma 'dan

115
00:05:34,210 --> 00:05:37,520
għaliex kienu jippruvaw
jikkomputa mogħdijiet sitt gradi out,

116
00:05:37,520 --> 00:05:38,870
jew simili seba gradi out.

117
00:05:38,870 --> 00:05:42,330
>> U li xi ħaġa li meta
int tagħmel bħal seba n,

118
00:05:42,330 --> 00:05:47,560
li ftit huwa verament iebsa ħafna u
huwa ħa r-sit tagħhom għal waqt.

119
00:05:47,560 --> 00:05:51,950
Allura waħda mill-affarijiet li aħna tip ta kellha
f'moħħu meta konna jidhru

120
00:05:51,950 --> 00:05:56,070
kif tagħmel dan kien kif taħseb
jiddistribwixxu l-database b'mod

121
00:05:56,070 --> 00:05:58,820
li din il-komputazzjoni
isir maniġġabbli.

122
00:05:58,820 --> 00:06:03,570
>> Allura dak li aħna ddeċidiet kien
li kulħadd fuq is-sit

123
00:06:03,570 --> 00:06:06,800
ma ħafna ta 'attività tagħhom fil-
iskola li dawn qed tip ta 'bbażati fuq.

124
00:06:06,800 --> 00:06:09,767
Mela jekk int fil-Harvard,
allura ħafna mill-poplu

125
00:06:09,767 --> 00:06:12,350
li int ser tkun qed tara
u transazzjoni ma fuq is-sit

126
00:06:12,350 --> 00:06:13,475
ser ikunu fil-Harvard.

127
00:06:13,475 --> 00:06:16,600
Huwa fil-fatt probabbilment simili 90% tal-
l-għalf li inti tagħmel fuq is-sit.

128
00:06:16,600 --> 00:06:20,510
>> Allura aħna iddeċieda li jifred
databases u joħolqu

129
00:06:20,510 --> 00:06:25,740
eżempju wieħed ta 'database MySQL
għal kull skola fin-netwerk.

130
00:06:25,740 --> 00:06:30,680
U filwaqt li tagħmel dan, jekk inti
avviż l-mogħdijiet li aħna jikkomputa

131
00:06:30,680 --> 00:06:32,050
huma biss fi ħdan l-iskola.

132
00:06:32,050 --> 00:06:35,120
Allura minflok ngħidu aħna, bħal issa
aħna għal sitt miljun utenti,

133
00:06:35,120 --> 00:06:41,080
u minflok li tagħmel kubiku n
fuq xi porzjon ta 'sitt miljun,

134
00:06:41,080 --> 00:06:43,850
huwa biss n kubiku fuq
10,000, li huwa ħafna aktar

135
00:06:43,850 --> 00:06:47,760
tip maniġġabbli ta 'komputazzjoni.

136
00:06:47,760 --> 00:06:50,920
>> Allura li kien tip ta 'l-ewwel
deċiżjoni arkitettoniku big

137
00:06:50,920 --> 00:06:55,210
li kellna biex jagħmlu dan ikkontribwixxa
lilna ma jmutu ftit xhur wara.

138
00:06:55,210 --> 00:06:58,250
U kien probabbilment
wieħed pretty importanti.

139
00:06:58,250 --> 00:07:04,935
>> Allura meta aħna ewwel twaqqaf is-sit kellna
biss wieħed kompjuter li konna running.

140
00:07:04,935 --> 00:07:06,060
Ma kienx fil-kamra dorm tagħna.

141
00:07:06,060 --> 00:07:06,851
Konna tikriha.

142
00:07:06,851 --> 00:07:10,780
I tip ta tgħallimt lezzjoni tiegħi għal
tipprova tmexxi sit minn dorm tiegħi

143
00:07:10,780 --> 00:07:15,040
kamra ftit xhur qabel, u
Harvard kważi ppruvaw kick me out.

144
00:07:15,040 --> 00:07:18,750
>> So I ended up kiri ta '
server off site dan iż-żmien.

145
00:07:18,750 --> 00:07:26,540
And I raden running oriġinarjament
-database u l-web server.

146
00:07:26,540 --> 00:07:29,280
Allura Apache huwa dak li konna
użu f'dan il-każ

147
00:07:29,280 --> 00:07:31,940
biex iservu l-paġni
mill-istess magna.

148
00:07:31,940 --> 00:07:35,710
U għaliex aħna mqassma l-

00:16:28,620 --> 00:16:32,510
Minħabba inqas Google qed taħdem
off ta 'lott ta' tagħmir distribwit

292
00:16:32,510 --> 00:16:34,930
li jkollhom mijiet
ta 'eluf ta' magni,

293
00:16:34,930 --> 00:16:40,200
imma l-idea kien hemm biex tikseb lott ta '
magni shitty li huma verament irħisa.

294
00:16:40,200 --> 00:16:41,530
I mean, li l-pass kbir.

295

>> Għaliex imbagħad huwa simili,
OK, dan huwa aktar superfluwa.

296
00:16:44,539 --> 00:16:45,830
Dawn mhux qed jitilfu informazzjoni.

297
00:16:45,830 --> 00:16:47,455
Huma ma jistennewx għalf li dejjem xogħol.

298

Huwa ħafna aktar maturi
attitudni minn eBay, li

299
00:16:51,307 --> 00:16:53,390
kienet l-unika ħaġa li
li tista 'tagħmel fil-ħin.

jistaqsi jekk inti [inaudible]

306
00:17:05,074 --> 00:17:08,511
estensjonijiet tiegħek għall Memcache,
għaliex ħaġa waħda stajt ndunat

307
00:17:08,511 --> 00:17:12,930
hija li, yeah, ma jkunx hemm verament
libreriji disponibbli tajbin għall-għalf DHT.

308
00:17:12,930 --> 00:17:14,972
Hemm dan kollu isbaħ
riċerka, iżda wkoll f'termini

309
00:17:14,972 --> 00:17:18,138
ta 'implimentazzjonijiet li attwalment jittrattaw
mal-kwistjonijiet kollha redundancy u kollha

310
00:17:18,138 --> 00:17:18,822
dawk l-affarijiet -

311
00:17:18,822 --> 00:17:22,920
>> Zuckerberg Mark: Yeah,
ħafna ta 'l-għalf - aħna

312

ma testendix neċessarjament Memcache.

313
00:17:25,280 --> 00:17:29,480
Aħna mibnija mazz ta 'għalf nfusna.

314
00:17:29,480 --> 00:17:32,470
Dritt issa, mhuwiex sors miftuħ.

315
00:17:32,470 --> 00:17:33,590
Aħna kkunsidrati tagħmel dan.

316
00:17:33,590 --> 00:17:37,410
U I tfisser, hemm ħafna ta 'xogħol li
tmur fis-teħid għalf sors miftuħ.

317
00:17:37,410 --> 00:17:42,020
U huwa fuq quċċata ta 'jekk jew le inti
tixtieq li jitilfu l-vantaġġ kompetittiv.

318
00:17:42,020 --> 00:17:43,150
Huwa tip ta 'ħasra.

319
00:17:43,150 --> 00:17:46,935
>> Għaliex naħseb li jekk konna biss
faċli biex jagħmlu xi ħaġa bħal dik,

320
00:17:46,935 --> 00:17:47,810
allura inti tista 'tagħmel dan.

321
00:17:47,810 --> 00:17:49,950
Inti tista 'biss jirrilaxxa l-kodiċi.

322
00:17:49,950 --> 00:17:55,430
Imma allura hemm ħafna ta 'appoġġ
u l-liċenzjar u dak kollu li Jittieħed.

323
00:17:55,430 --> 00:17:57,030
Sibna li huwa kien annoying.

li Guy seduta hemm dritt

magħmula waqt li kien għadu
fl-California.

327
00:18:09,050 --> 00:18:16,380

tal-tfittxijiet li
konna tipprova tagħmel.

329
00:18:18,520 --> 00:18:22,330
U aħna iddeċieda li
tkun ħaġa jibred

330
00:18:22,330 --> 00:18:26,750
tagħmel biex jagħmlu serje
ta 'magni mqassma

332
00:18:29,147 --> 00:18:30,980
X'hemm l-istruttura
li tuża, McCollum?

ħsibt dwar teħid dik miftuħa.

335
00:18:36,270 --> 00:18:42,670
Iżda li meta aħna tip ta kellha tagħmel
din il-ħidma biex toħroġ bi liċenzja.

342
00:19:01,160 --> 00:19:06,060
I raden meta, kif inti jikbru,
l-iktar ħaġa importanti

343
00:19:06,060 --> 00:19:07,060
huwa li jkun nies intelliġenti.

344
00:19:07,060 --> 00:19:09,630

345
00:19:09,630 --> 00:19:13,915
Jekk taħseb dwar kif, tekniku
Jittieħed lieva li I kien jitkellem dwar

346
00:19:13,915 --> 00:19:20,960
Sabiex tirrispondi għal din Guy
kwistjoni, kif it-teknoloġija ssir

347
00:19:20,960 --> 00:19:23,940
aktar ġeneriku u inqas
għaljin, il-punt ta 'lieva

348
00:19:23,940 --> 00:19:26,110
isir aktar fil-poplu.

349
00:19:26,110 --> 00:19:29,860
Mela jekk inti taħseb dwar
din minn perspettiva

350
00:19:29,860 --> 00:19:36,610
ta 'persuna li nies ħin mgħoddi
jew il-ħin utent jintefqu, jew paġna ħsieb

351
00:19:36,610 --> 00:19:40,590
analiżi, minħabba
teknoloġija issa, in-nies

352
00:19:40,590 --> 00:19:46,220
huma ħafna aktar leveraged
biex tagħmel affarijiet aktar

353
00:19:46,220 --> 00:19:49,380
u jkun aktar importanti fl-ekwazzjoni.

354
00:19:49,380 --> 00:19:53,130
>> Minħabba dan, huwa verament importanti
biex jiksbu l-aktar nies intelliġenti.

355
00:19:53,130 --> 00:19:58,660
U wkoll, I tfisser, meta int żgħir
kumpanija, inti tista 'tkun verament nimble

356
00:19:58,660 --> 00:20:00,050
u jiksbu ħafna ta 'għalf magħmul.

357
00:20:00,050 --> 00:20:02,845
U hemm relattivament
ftit burokrazija.

358
00:20:02,845 --> 00:20:06,397
Mela jekk għandek nies intelliġenti li jistgħu jieħdu
vantaġġ ta 'dak li jibnu affarijiet jibred,

359
00:20:06,397 --> 00:20:07,230
allura li biża.

360
00:20:07,230 --> 00:20:10,790

tfassil affarijiet ġodda.

362
00:20:15,990 --> 00:20:18,530
Hemm Ma tantx
burokrazija korporattiva s'issa.

363
00:20:18,530 --> 00:20:20,342
So I ma jkollhom
iskart ħafna ħin fuq dan.

364

365
00:20:26,820 --> 00:20:29,630

u kkonsultat ma 'avukati s'issa?

367
00:20:36,090 --> 00:20:38,860

li taħdem għal me full-time.

368
00:20:38,860 --> 00:20:43,830
>> UDJENZA: OK, dan huwa big
parti ta 'tmexxija ta' negozju?

369
00:20:43,830 --> 00:20:47,309
Kieku inti jirrakkomandaw taħdem
fuq [inaudible] kmieni?

370
00:20:47,309 --> 00:20:50,291

371
00:20:50,291 --> 00:20:52,550
>> Zuckerberg Mark: Aħna ma.

372
00:20:52,550 --> 00:20:59,980
U li, I raden, sakemm
xi dwejjaq aktar tard.

373
00:20:59,980 --> 00:21:04,502
Getting Jittieħed stabbilit
verament tajjeb hija tajba.

374
00:21:04,502 --> 00:21:05,960
Getting Jittieħed nadif huwa verament tajba.

375
00:21:05,960 --> 00:21:09,590
>> U, I mean, ħadd qatt ser
biex jgħidlek avukat huwa ħażin.

376
00:21:09,590 --> 00:21:13,790
Huwa kollha biss kwistjoni ta 'opportunità
ispiża u dak li inti jipprijoritizzaw.

377
00:21:13,790 --> 00:21:19,820
I raden li, fil-każ tagħna, issa għandna
li jittrattaw ma 'mazz ta' għalf li

378
00:21:19,820 --> 00:21:23,030
ma twaqqaf sew fil-bidu.

379
00:21:23,030 --> 00:21:25,010
Ħafna mill-għalf huwa ttrattat.

380
00:21:25,010 --> 00:21:26,620
Huwa lanqas a big deal aktar.

381
00:21:26,620 --> 00:21:33,450
>> Iżda minflok tkellem lill-avukati
kmieni, aħna kienu qed jagħmlu Jittieħed.

382
00:21:33,450 --> 00:21:37,960
U naħseb li dan kien probabbilment
l-użu korrett ta 'żmien tagħna.

383
00:21:37,960 --> 00:21:41,530
Naħseb li karatteristika waħda jibred
ta 'lott tal-kumpaniji li jispiċċaw

384
00:21:41,530 --> 00:21:44,860
tkun verament ta 'suċċess, ma
li aħna verament ta 'suċċess,

385
00:21:44,860 --> 00:21:46,720
imma I raden aħna wkoll
jaqgħu f'din barmil,

386
00:21:46,720 --> 00:21:49,424
hija li dawn bdew off bħala
xi ħadd tipprova tagħmel xi ħaġa

387
00:21:49,424 --> 00:21:51,340
jibred u mhux xi ħadd
tipprova tagħmel kumpanija.

388
00:21:51,340 --> 00:21:54,800

389
00:21:54,800 --> 00:21:59,540
Inti tip ta 'jkunu - Google ħareġ mill-
Larry u Sergey tal Dissertazzjoni PhD

390
00:21:59,540 --> 00:22:04,500
fil Stanford, u Yahoo ħareġ mill-
biss, I raden, wkoll xi guys Stanford

391
00:22:04,500 --> 00:22:06,510
biss tip ta 'screwing
madwar fil-kamra dorm tagħhom.

392
00:22:06,510 --> 00:22:11,840
U eBay ħareġ mill xi Guy jippruvaw
jibnu suq għall ħabiba tiegħu

393
00:22:11,840 --> 00:22:14,342
għall-iskambju dispensers Pez.

394
00:22:14,342 --> 00:22:15,842
Amazon kien ftit aktar kkalkulat.

395
00:22:15,842 --> 00:22:20,290

396
00:22:20,290 --> 00:22:24,067
>> So I ma jistax jimmaġina li kwalunkwe minn dawk
nies verament kellu parir li ħafna,

397
00:22:24,067 --> 00:22:25,900
u jidher li jkollhom
jinħadmu OK għalihom.

398
00:22:25,900 --> 00:22:28,191
Iżda, I jfisser, fl-istess ħin
Jien mhux ser ipoġġu hawn

399
00:22:28,191 --> 00:22:30,920
u jgħidlek biex ma tikseb pariri dwar Jittieħed.

400
00:22:30,920 --> 00:22:35,810
U ħafna drabi nies
huma ftit wisq attenta, wisq.

401
00:22:35,810 --> 00:22:40,600
Naħseb li huwa aktar utli li jagħmlu
affarijiet jiġri u mbagħad ruhna aktar tard

402
00:22:40,600 --> 00:22:43,740
milli huwa li tagħmel ċert li inti
dot għajnejn I tiegħek issa u mbagħad

403
00:22:43,740 --> 00:22:44,740
biss ma jsibux Jittieħed jsir.

404
00:22:44,740 --> 00:22:47,500

405
00:22:47,500 --> 00:22:49,430
Yeah.

406
00:22:49,430 --> 00:22:50,460
Mur għaliha.

407
00:22:50,460 --> 00:22:53,436

Taħseb li se tilħaq
f'dak il-punt kwalunkwe ħin hekk?

410

I mean, I jaħsbu li - I

414
00:23:18,290 --> 00:23:21,830
I mean, aktar kumpaniji huma
bdiet fuq bħal koppja ta 'ideat,

415
00:23:21,830 --> 00:23:25,800
u dawn huma ftit
affarijiet li jagħmlu tajjeb.

416
00:23:25,800 --> 00:23:29,120
So, I mean, Yahoo kienet simili aħna qed
ser jorganizza din l-informazzjoni

417
00:23:29,120 --> 00:23:31,160
fid-dinja bħall mill-direttorju.

418
00:23:31,160 --> 00:23:33,350
U li kien dak li
bdew jagħmlu,

419
00:23:33,350 --> 00:23:38,860
u allura dawn it-tip ta diversifikati out
bħala ħin marru fuq u mibnija Jittieħed aktar.

420
00:23:38,860 --> 00:23:42,910
U ħafna ta 'li Jittieħed huwa simili
il-qalba tan-negozju tagħhom issa.

421
00:23:42,910 --> 00:23:45,460
I mean, huwa simili li
ma oriġinarjament do tfittxija.

422
00:23:45,460 --> 00:23:47,740
U issa direttorju sempliċement ma jeżistix.

423
00:23:47,740 --> 00:23:49,280
Hija sucks.

424
00:23:49,280 --> 00:23:52,880
M'hemm l-ebda utilità għal dan.

425
00:23:52,880 --> 00:23:56,320
>> I mean, ħaġa big Google kienet
eżatt bħal dawn ma PageRank.

426
00:23:56,320 --> 00:24:02,320
U mbagħad, I raden, minn
PageRank, huma għandhom search.

427
00:24:02,320 --> 00:24:05,960
U issa huma tip ta jestendi dak li
do tip simili oħra ta 'algoritmi,

428
00:24:05,960 --> 00:24:07,830
tiftix fi spazji oħra.

429
00:24:07,830 --> 00:24:11,090
Iżda, I mean, inti tista 'tip ta jgħidlek kif
l-għalf oħra li dawn qed jagħmlu

430
00:24:11,090 --> 00:24:12,330
huwa tip ta tanġenzjali.

431
00:24:12,330 --> 00:24:16,220
U huwa simili li qed jippruvaw
verament diffiċli li tagħmel PageRank

432
00:24:16,220 --> 00:24:19,080
u tipi oħra ta '
algoritmi li huma ħafna

433
00:24:19,080 --> 00:24:23,660
simili għal dak ix-xogħol tagħhom
spazji, u huwa biss mhux bħala eleganti

434
00:24:23,660 --> 00:24:27,460
jew pur ta 'idea kif
dik oriġinali kienet.

435
00:24:27,460 --> 00:24:30,590
>> Għalhekk fl Facebook, per eżempju,
meta hija biss ltqajna beda,

436
00:24:30,590 --> 00:24:32,840
dak li ħsibt kienet l-aktar
Ħaġa interessanti kienet biss

437
00:24:32,840 --> 00:24:36,010
biex ikunu jistgħu tip fl-isem ta 'xi ħadd
u nsib informazzjoni dwarhom.

438
00:24:36,010 --> 00:24:38,800
U kien hemm kważi l-ebda ta '
l-għalf li kien hemm issa.

439

U ġeneralment, il-kumpanija
se tagħmel ukoll, minħabba I

462
00:25:49,030 --> 00:25:51,155
I mean, naħseb li l-
coolest ħaġa dwar ritratti

463
00:25:51,155 --> 00:25:54,849
hija li inti tista 'tag
lilhom u l-mod li

li juża huma jafdaw l-poplu intelliġenti.

491
00:27:08,560 --> 00:27:15,010
Allura aħna definittivament għandhom xi nies fil-

492
00:27:15,010 --> 00:27:19,795
u naħseb li ħafna mill-poplu fil-

jgħidu li xi ħaġa hija ġeneralment

495
00:27:32,050 --> 00:27:36,590
prattika tajba biex tmur fuq dan,
allura huwa relattivament - imbagħad

496

għal dak pretty faċilment.

aħna kien jaf li ridna

għall-appoġġ biss in-nies

503
00:27:58,969 --> 00:28:01,010
So, I mean, hemm ebda
kunċett reali ta 'bla limitu.

504
00:28:01,010 --> 00:28:05,240
Huwa biss inti għandek iżżomm fuq iż-żieda
Jittieħed, iżommu abbord żżid ħażna.

tal jaħdem bħala seamlessly possibbli.

506
00:28:09,337 --> 00:28:11,170
Allura l-ewwel ħaġa li
konna tipprova tagħmel

507
00:28:11,170 --> 00:28:16,140
huwa, ukoll, ejja tevalwa
dawn il-kumpaniji li

U allura aħna qed simili, id-dritt.

512
00:28:25,440 --> 00:28:29,200
Well, aħna ma verament irridu li jmorru
ma 'dan l-approċċ uniku kaxxa kbira.

513
00:28:29,200 --> 00:28:33,530
Aħna tixtieq li tmur ma jkollhom biss

515
00:28:37,400 --> 00:28:40,360

li konna se jkollhom
xi kwistjonijiet ma 'dan.

konna se jkollhom

u kull wieħed mill-ritratti tiegħek
huwa tliet megabytes,

526

allura inti tista 'upload 90
megabytes biex Facebook.

527
00:29:25,330 --> 00:29:26,610
U dan it-tip ta sucks.

Kull dritt.

529
00:29:27,110 --> 00:29:31,790
I mean, sucks għaliex in-nies
għandhom tendenza li jkollhom konnessjonijiet ma ottimali

530
00:29:31,790 --> 00:29:37,770
u minħabba router tagħna - I
raden iktar routers huma stabbiliti

531
00:29:37,770 --> 00:29:39,960
biex ikunu jistgħu jimmaniġġjaw biss
a gigabit fi żmien,

532

biss tikseb router ġdid u ġġibu stabbilit.

538
00:29:54,720 --> 00:30:02,000

541
00:30:08,650 --> 00:30:14,380

00:32:31,270 --> 00:32:36,240
U billi jagħmlu dan, aħna sort
ta 'jkollu - aħna par

587
00:32:36,240 --> 00:32:40,370
nies ġodda li huma ġejjin ma
xi - bħall-aħjar nies

588
00:32:40,370 --> 00:32:44,720
li huma tip ta 'fil-quċċata
tal-katina, u allura aħna

589
00:32:44,720 --> 00:32:48,650
jkollhom magħhom tip ta 'xogħol ma' dawk
nies meta l-ewwel jidħlu fil,

590
00:32:48,650 --> 00:32:51,340
jitgħallmu l-għalf li
dawn qed jaħdmu fuq li - hekk

591
00:32:51,340 --> 00:32:53,580
li l-guys ġodda, bħall-
il-klassi li jmiss,

592
00:32:53,580 --> 00:32:56,870
tista 'tip ta' jitgħallmu dak li xi wħud
il-persuni li bħalissa huma

593
00:32:56,870 --> 00:32:58,290
fil-kumpanija qed jaħdmu fuq.

594
00:32:58,290 --> 00:33:02,270
U naħseb li tagħmel dan, huma pick
l-istil u l-metodi li aħna

595
00:33:02,270 --> 00:33:03,540
tuża biex tagħmel Jittieħed.

>> Imma naħseb li huwa
bidliet pretty malajr.

597
00:33:07,940 --> 00:33:12,340
I think wieħed differenza bejn
il-mod Jittieħed jaħdem f'kumpanija

598
00:33:12,340 --> 00:33:16,600
u l-mod Jittieħed xogħlijiet fl-iskola hija
li dan huwa proċess iterattiv ħafna.

599
00:33:16,600 --> 00:33:21,880
U huwa sbieħ meta inti tikseb id-dritt Jittieħed
l-ewwel darba, imma aħna ma bżonn.

600
00:33:21,880 --> 00:33:24,810
U naħseb li ħafna ta 'kumpanniji
jgħaddu fażijiet, jew stadji,

601
00:33:24,810 --> 00:33:26,810
fejn dawn ma jsibux Jittieħed
dritt l-ewwel darba.

602
00:33:26,810 --> 00:33:29,560
>> Bħal Microsoft - I
mean, I ma nafx meta

603
00:33:29,560 --> 00:33:32,589
l-aħħar darba kienet li kellhom
prodott tajjeb qabel Version 4.

604
00:33:32,589 --> 00:33:34,380
Iżda mill-ħin li
jiksbu l Version 4, huwa

605
00:33:34,380 --> 00:33:37,286
bħal dejjem tajba għall-aktar parti.

606
00:33:37,286 --> 00:33:39,380
U naħseb li x-xogħlijiet
out pretty tajjeb għalihom.

607
00:33:39,380 --> 00:33:42,240
U, I mean, Google dejjem
rilaxxi Jittieħed tagħhom fl beta.

608
00:33:42,240 --> 00:33:50,350
>> So I raden aħna jippruvaw li jkollhom multiple
nies jaħdmu fuq l-istess ħaġa,

609
00:33:50,350 --> 00:33:53,810
sabiex kulħadd jistgħu jitgħallmu minn
xulxin u tip ta 'pick off

610
00:33:53,810 --> 00:33:58,800
xi wħud mill-iżbalji li jistgħu jkunu
magħmula li nistgħu nnaqqsu pretty malajr.

611
00:33:58,800 --> 00:34:01,676
Iżda bħal, I raden fil
ġenerali, l-idea hija

612
00:34:01,676 --> 00:34:04,050
li ma għandhom ikunu
perfetta l-ewwel darba madwar.

613
00:34:04,050 --> 00:34:07,457
U sakemm ikollok l-
arkitettura bħala dritt possibbli,

614
00:34:07,457 --> 00:34:09,290
allura ħafna ta 'l-oħra
Jittieħed implimentazzjoni

615
00:34:09,290 --> 00:34:11,581
mhux se jkun kbir ta '

00:34:11,581 --> 00:34:13,190
xogħol li barra fi kwalunkwe ħin.

617
00:34:13,190 --> 00:34:16,449
I know jekk thats tip ta 'tweġib
il-kwistjoni li inti tlabt lili.

618

>> UDJENZA: Allura issa, meta
issib xi ħaġa

li inti tixtieq li tagħmel li inti
ma jafux tant dwar,

620
00:34:22,449 --> 00:34:24,449
inti tista 'tistaqsi xi wħud minn dawn
nies li qed jaħdmu għalik,

621
00:34:24,449 --> 00:34:25,449
jew tista 'tikseb nies ġodda.

622
00:34:25,449 --> 00:34:28,657
Imma meta bdejt, kien biss tip
ta 'int u roommate tiegħek bħala student.

623
00:34:28,657 --> 00:34:32,199
U ovvjament, kien hemm dominju
kwistjonijiet tal-konoxxenza ta 'xjenza tal-kompjuter

624
00:34:32,199 --> 00:34:34,449
li inti kellhom jittrattaw
u inti ma taf dwar.

Ridt tiddeċiedi li tieħu ċerti klassijiet?

627
00:34:39,222 --> 00:34:39,971
Did ikollok kotba?

628
00:34:39,971 --> 00:34:43,278
Ma tmur kiri jew tikseb
involut ma 'xi nies aktar?

629
00:34:43,278 --> 00:34:45,758

dawk il-kwistjonijiet ta 'tagħlim

kif għamilna ħafna minnha.

ta 'mhux kiri ta' nies għall-ħiliet,

u kienet tagħmel dan
għal 10 jew 15-il sena,

jfisser li huma jistgħu jagħmlu dan.

neċessarjament jaf li ħafna dwar

I biss imsemmija qabel,

kultant bħal dawn qed problemi soċjali.

U huwa simili - wieħed
ħaġa li naħseb huwa

906
00:49:16,310 --> 00:49:20,976
tassew interessanti hu - jekk għandek
100 jew 150 ħbieb, kif ukoll jagħmlu

li huma forsi bħall-ħames persuni

U li mhux xi ħaġa
li inti tista 'verament

910
00:49:29,490 --> 00:49:32,110
twieġeb dritt issa, għaliex
l-konnessjonijiet huma binarja.

911

Inti jew huma konnessi jew int le.

912
00:49:33,970 --> 00:49:39,740

dwar kif nistgħu disinn xi ħaġa

913
00:49:39,740 --> 00:49:43,990
li tagħmel dan hekk li n-nies
setgħux jesprimu kif kienu qrib

1 sa 10, li ma tkunx taħdem.

forsi l-persuna bi 30 biss

928

għandha limitu ogħla biex isiru
xi ħadd fuq xi ħabib fuq Facebook.

Imma I dehret li din kieku
probabbilment jkun ftit aktar preċiża,

għaliex l-ebda wieħed ikun ser

941
00:51:05,500 --> 00:51:07,340
allura dan it-tip ta 'jfisser xi ħaġa.

-persuni li jaħdmu fuq Facebook verament

1024
00:55:14,340 --> 00:55:17,430
jħobbux jaħdmu fuq Facebook,
I think, għall-parti l-kbira,

1025
00:55:17,430 --> 00:55:19,840
u jqattgħu ħafna
ħin tagħhom tagħmel dan.

1026
00:55:19,840 --> 00:55:22,800
U bħal, lott ta 'l-
ħin li dawn qed infiq,

1027
00:55:22,800 --> 00:55:25,240
li jqattgħu jaħdmu fuq
għalf li jista 'jkun

1028
00:55:25,240 --> 00:55:28,890
tip ta strateġikament importanti
dak li aħna qed tipprova tagħmel f'dak il-punt.

1029
00:55:28,890 --> 00:55:31,760
Iżda wkoll, ħafna nies biss
mess madwar il-bażi ta 'kodiċi,

1030
00:55:31,760 --> 00:55:36,090
u tip ta 'tpoġġi IF-dikjarazzjonijiet
hemm dak simili, jekk l-utent huwa me,

1031
00:55:36,090 --> 00:55:39,240
allura tpoġġi dan fil hemmhekk.

1032
00:55:39,240 --> 00:55:44,050
>> U so I walk madwar differenti
postijiet tan-nies matul il-jum,

1033
00:55:44,050 --> 00:55:45,330
jew nies ġejjin u tkellem lili.

1034
00:55:45,330 --> 00:55:49,610
Bħal, I istiva ħinijiet tal-uffiċċju CEO bħala
ċajta, bħal 2:00-04:00 kuljum -

1035
00:55:49,610 --> 00:55:51,077
mhux illum.

1036
00:55:51,077 --> 00:55:53,910
U nies biss jidħlu u urini
Jittieħed differenti li qed isir,

1037
00:55:53,910 --> 00:55:57,060
u ħafna ta 'dan huwa
relattivament jibred, u l-għalf

1038
00:55:57,060 --> 00:55:59,530
li jien mhux se jkollhom
neċessarjament meqjusa.

1039
00:55:59,530 --> 00:56:02,740
>> So I mean, inti tlabt
qabel jekk konna iffrankar,

1040
00:56:02,740 --> 00:56:06,400
jekk konna arkivjar, profil qodma
informazzjoni, u waħda mir-raġunijiet

1041
00:56:06,400 --> 00:56:08,940
għaliex I qal li aħna
tista 'tibda tagħmel dan huwa

1042
00:56:08,940 --> 00:56:13,124
għaliex wieħed mill-guys fil-kumpanija
ħarāet bil xi ħaġa fejn huwa simili,

1043
00:56:13,124 --> 00:56:16,290
sabiex inti tmur għall-paġna ħabib tiegħek, u
dan juri ħbieb aġġornati reċentement tiegħek.

1044
00:56:16,290 --> 00:56:18,250
U allura inti ikklikkja fuq li,
u dan juri l-profil ġdida tagħhom.

1045
00:56:18,250 --> 00:56:20,180
Iżda hemm ebda indikazzjoni
ta 'dak li nbidlet.

1046
00:56:20,180 --> 00:56:25,290
>> Allura waħda mill-guys għamlu xi ħaġa li
żżomm verżjoni l-qadima ta 'profil tiegħu,

1047
00:56:25,290 --> 00:56:29,690
u mbagħad jagħmilha tant li meta inti
Mur fil-profil tiegħu meta aġġornamenti dan,

1048
00:56:29,690 --> 00:56:32,380
jenfasizza fil-isfar
partijiet minnha li ġew mibdula.

1049
00:56:32,380 --> 00:56:33,880
U naħseb li dan huwa pretty jibred.

1050
00:56:33,880 --> 00:56:37,385
U mhuwiex proġett enormi -
I mean, fil-fatt tip ta 'hija,

1051
00:56:37,385 --> 00:56:39,630
jekk għandna nibdew ħażna
informazzjoni ta 'kulħadd.

1052
00:56:39,630 --> 00:56:42,720
>> Imma I mean, huwa kemmxejn jibred.

1053
00:56:42,720 --> 00:56:48,250
Huwa mhuwiex it-tip ta 'ħaġa li inti
bilfors huma marbuta li toħroġ,

1054
00:56:48,250 --> 00:56:52,820
imma I definitely think it'sa pretty
titjib kbir fuq dak li għandna issa.

1055
00:56:52,820 --> 00:56:57,330
Issa, huwa verament diffiċli biex tmur
profil ta 'xi ħadd u jgħidlek liema mibdula.

1056
00:56:57,330 --> 00:57:01,080
U dan huwa biss l-aktar
Eżempju reċenti li għandi.

1057
00:57:01,080 --> 00:57:05,380
>> UDJENZA: Do ikollok ħin biex jippermettu
nies biex jibdlu l-ħarsa ta 'kull paġna?

1060
00:57:09,730 --> 00:57:12,970
>> Zuckerberg Mark: So, I
ma jridux jagħmlu dan.

1061
00:57:12,970 --> 00:57:17,230
U r-raġuni għaliex naħseb
li Facebook huwa direttorju,

1062
00:57:17,230 --> 00:57:20,051
u l-iskop primarju
huwa li tfittex up xi ħadd.

1063
00:57:20,051 --> 00:57:20,550
Dritt?

1064
00:57:20,550 --> 00:57:22,870
Bħal tip fl-isem tagħhom u jiksbu
xi informazzjoni dwarhom.

1065
00:57:22,870 --> 00:57:24,690
U waħda mill-affarijiet
li tassew utli

1066
00:57:24,690 --> 00:57:27,190
hija dik il-paġna ta 'kulħadd hija
strutturat bl-istess mod.

1067
00:57:27,190 --> 00:57:29,100
>> Mela jekk inti tixtieq li tara
jekk xi ħadd huwa wieħed,

1068
00:57:29,100 --> 00:57:32,780
inti ma għandekx li skennjati l-kolonni
sakemm ikollok l-istatus relazzjoni.

1069
00:57:32,780 --> 00:57:34,430
Inti biss taf fejn li hu.

1070
00:57:34,430 --> 00:57:38,040
Allura inti ikklikkja, mur - tiegħek
għajnejn biss mur li ħaġa.

1071
00:57:38,040 --> 00:57:43,117
Imma jekk kellek nies differenti
jinbidlu CSSes tagħhom b'modi differenti,

1072
00:57:43,117 --> 00:57:44,950
allura li jista 'jsir
annoying - speċjalment

1073
00:57:44,950 --> 00:57:49,140
jekk in-nies qed jagħmlu għalf bħal dlam
test blu fuq sfond iswed.

1074
00:57:49,140 --> 00:57:52,985
Huwa biss gets tip ta 'obnoxious.

1075
00:57:52,985 --> 00:57:57,440
>> UDJENZA: Kemm irnexxew
l Facebook [inaudible] kien,

1076
00:57:57,440 --> 00:58:02,390
u dak li tara kif id-differenzi
fl-iskop [inaudible]?

1077
00:58:02,390 --> 00:58:05,360

1078
00:58:05,360 --> 00:58:08,520
>> Zuckerberg Mark: L-iskop - għal
me, l-iskola għolja wieħed kien l-istess.

1079
00:58:08,520 --> 00:58:12,130
Naħseb li l-applikazzjoni -
dan se probabbilment

1080
00:58:12,130 --> 00:58:16,460
ħoss pretty stupid - imma jixtiequ
tfittex nies up, I think,

1081
00:58:16,460 --> 00:58:19,260
huwa tip ta 'xewqa umana qalba.

1082
00:58:19,260 --> 00:58:20,470
Dritt?

1083
00:58:20,470 --> 00:58:23,310
Naħseb li n-nies biss jixtiequ
taf Jittieħed dwar persuni oħra.

1084
00:58:23,310 --> 00:58:26,434
Għalhekk naħseb li tipprovdi
interface fejn in-nies jistgħu biss

1085
00:58:26,434 --> 00:58:28,850
tip fl-isem ta 'xi ħadd u jiksbu
xi informazzjoni dwarhom

1086
00:58:28,850 --> 00:58:31,050
huwa ġeneralment ħaġa pretty utli.

1087
00:58:31,050 --> 00:58:32,410
Allura tkabbir kien pjuttost tajba.

1088
00:58:32,410 --> 00:58:35,680
>> Kien iebsa biex insemmu
eżattament kif jitkejjel dan,

1089
00:58:35,680 --> 00:58:38,676
għaliex meta għamilna kulleġġ,
aħna miftuħa it up fil-Harvard.

1090
00:58:38,676 --> 00:58:41,050
Imbagħad aħna miftuħa it up fi
kulleġġi koppja madwar Harvard.

1091
00:58:41,050 --> 00:58:45,710
U l-idea kienet dejjem, konna
verament qasir fuq flus u tagħmir.

1092
00:58:45,710 --> 00:58:48,390
Għalhekk, filwaqt li jkollna ftit
tagħmir kemm jista 'jkun,

1093
00:58:48,390 --> 00:58:49,740
irridu li timmassimizza t-tkabbir tagħna.

1094
00:58:49,740 --> 00:58:53,709
Allura aħna tixtieq li tniedi
fl-iskejjel li aħna

1095
00:58:53,709 --> 00:58:56,000
think ser jikbru l-
aktar rapida, ibbażata fuq il-fatt

1096
00:58:56,000 --> 00:58:58,458
li l-poplu f'dawk l-iskejjel
huma se jkollhom l-aktar

1097
00:58:58,458 --> 00:59:01,655
numru ta 'ħbieb fil-
skejjel li aħna qed diġà.

1098
00:59:01,655 --> 00:59:03,530
Aħna ħa differenti
approċċ għall-iskola għolja,

1099
00:59:03,530 --> 00:59:05,670
għaliex nistgħu biss tniedi
kullimkien fl-istess ħin.

1100
00:59:05,670 --> 00:59:07,580
Allura aħna ma verament jafu
kif hija kienet se jikbru.

1101
00:59:07,580 --> 00:59:10,704
Naħseb li dejjem tikber fuq aktar minn 5,000
persuna kuljum, li hija pjuttost tajba.

1102
00:59:10,704 --> 00:59:14,533

1103
00:59:14,533 --> 00:59:15,487

1111
00:59:35,030 --> 00:59:38,320
I remember jargumenta mal-ġenituri tiegħi
dwar dan, għaliex wara I kważi

1112
00:59:38,320 --> 00:59:44,020
ltqajna kicked mill-iskola għal dan
proġett li għamilt qabel Facebook,

1113
00:59:44,020 --> 00:59:47,217
kienu simili, dak tajjeb jista '
possibbilment jaqgħu li jagħmlu xi ħaġa ġdida?

1114
00:59:47,217 --> 00:59:48,800
U jien simili, l-ebda, dan huwa pretty jibred.

1115
00:59:48,800 --> 00:59:52,605
Just jimmaġina kif jibred ikun jekk
inti tista 'biss tip fl-isem ta' xi ħadd

00:59:52,605 --> 00:59:54,120
u nikseb xi informazzjoni dwarhom.

U kienu biss nixtieq, I ma tara.

1118
00:59:56,050 --> 00:59:58,662
U jien simili, ukoll, aħna ser
biss tagħmel dan fil-Harvard għal issa,

1119
00:59:58,662 --> 01:00:01,620
iżda jimmaġina x'jiġri jekk ġurnata waħda,
inti tista 'biss tip fl-isem ħadd

li tippreserva l-
integrità tan-netwerk,

u wkoll biex tagħmel dan hekk
li huwa aktar utli - I

1129
01:00:28,190 --> 01:00:32,668

għaliex inti jitgħallmu l-aktar meta
inti isfida lilek innifsek, right?

1136
01:00:51,653 --> 01:00:57,980
Allura bħal 161 biss ruined ħajja tiegħi,
u I tgħallmu tant minnha.

1137
01:00:57,980 --> 01:01:01,620

tagħmel Jittieħed bl-aktar mod effiċjenti,

iżda tistabbilixxi l-qafas
b'mod pretty effiċjenti.

iżda dan ma jfissirx li huwa l-
mod finali li se jiġri.

1166
01:02:36,200 --> 01:02:40,710
>> Hekk per eżempju, in-nies li tenfasizza
isfar dak li l-bidliet huma

1167
01:02:40,710 --> 01:02:44,510
fil-profil tagħhom - naħseb li
biss il-kunċett ta 'jenfasizzaw

1168
01:02:44,510 --> 01:02:47,520
Jittieħed li nbidlet hija
verament tajba, iżda l-interface

1169
01:02:47,520 --> 01:02:50,960
li dan Guy użati għal mhuwiex
dak li naħseb huwa l-aħjar waħda.

1170
01:02:50,960 --> 01:02:54,130
U l-mod li hu ħażna
l-informazzjoni tal-profili qodma

1171
01:02:54,130 --> 01:02:55,410
mhuwiex l-aħjar waħda.

1172
01:02:55,410 --> 01:02:58,201
U dan it-tip ta 'jibred, għaliex
kien biss tagħmel dan għalih innifsu.

1173
01:02:58,201 --> 01:03:01,790
Imma jekk konna qatt ser tagħmel
xi ħaġa jgħixu barra minn dak li

1174
01:03:01,790 --> 01:03:04,060
I trid, nagħmlu b'mod differenti.

1175
01:03:04,060 --> 01:03:05,540
U huwa aktar biss bħal mock-up.

1176
01:03:05,540 --> 01:03:07,814
>> UDJENZA: Allura simili, l-ideat
ġejjin mill-art, up,

1177
01:03:07,814 --> 01:03:10,230
u mbagħad [? huwa biss?]
[? tossed?] [? tistabbilixxi l-linja? ?]

1178
01:03:10,230 --> 01:03:12,260
>> Zuckerberg Mark: I
jfisser, din tmur żewġ modi.

1179
01:03:12,260 --> 01:03:14,995
U jien ma unopinionated kompletament.

1180
01:03:14,995 --> 01:03:21,072

1181
01:03:21,072 --> 01:03:22,322
MICHAEL D. SMITH: [inaudible].

1182
01:03:22,322 --> 01:03:28,298

1183
01:03:28,298 --> 01:03:30,788
>> UDJENZA: I attwalment jkollhom
mistoqsija dwar il-[inaudible].

1184
01:03:30,788 --> 01:03:35,270
Allura, li tmur lura madwar il-
[Inaudible] u [inaudible] privatezza.

1185
01:03:35,270 --> 01:03:37,760
U huwa pjattaforma differenti?

1186
01:03:37,760 --> 01:03:38,756
>> Zuckerberg Mark: Yeah.

1187
01:03:38,756 --> 01:03:41,744
>> Udjenza: Allura nies kulleġġ
aktar minn 18 u permess

1188
01:03:41,744 --> 01:03:44,483
li post kwalunkwe ritratti huma
jixtiequ, u dawn mhux qed verament

1189
01:03:44,483 --> 01:03:47,720
inkriminanti infushom, ħlief
possibilment għal drogi u alkoħol?

1190
01:03:47,720 --> 01:03:52,202
Stajt tidher stampi fuq
Facebook fejn iżgħar tiegħi

1191
01:03:52,202 --> 01:03:54,692
kuġini huma xorb
u għalf bħal dik.

1192
01:03:54,692 --> 01:04:00,170
Imma meta inti tmur għall-iskola għolja
gidjien, dawn qed 15 u 16 u iżgħar.

1193
01:04:00,170 --> 01:04:03,158
>> U huma inti guys biss
qal, huwa l-internet,

1194
01:04:03,158 --> 01:04:06,644
u jekk huma jixtiequ li tinkrimina
infushom u affarijiet bħal dik,

1195
01:04:06,644 --> 01:04:07,640
hija li OK?

1196
01:04:07,640 --> 01:04:11,624
Jew inti guys jiffiltraw l-istampi
studenti tal-iskola li għolja imqiegħed

1197
01:04:11,624 --> 01:04:13,118
u l-informazzjoni li jiktbu?

1198
01:04:13,118 --> 01:04:15,435
Jew inti biss [inaudible]?

1199
01:04:15,435 --> 01:04:18,310
Zuckerberg Mark: Allura ħafna ta 'l-
soluzzjonijiet li aħna toħroġ bi Jittieħed

1200
01:04:18,310 --> 01:04:23,230
mhumiex teknika jew organizzattiva,
iżda biss applikazzjoni tal-pressjoni soċjali

1201
01:04:23,230 --> 01:04:24,580
b'modi tajba.

1202
01:04:24,580 --> 01:04:28,740
Allura Myspace għandha - kważi
terz tal-persunal tagħhom

1203
01:04:28,740 --> 01:04:32,660
huwa l-monitoraġġ l-istampi li
nikseb uploaded għal pornografija.

1204
01:04:32,660 --> 01:04:36,270
Aħna bilkemm qatt xi
pornografija uploaded,

1205
01:04:36,270 --> 01:04:39,290
u naħseb li ħafna ta '
ir-raġuni hija li n-nies

1206
01:04:39,290 --> 01:04:44,470
jużaw ismijiet reali tagħhom fuq Facebook, u
indirizz email tiegħek reali għall-iskola.

1207
01:04:44,470 --> 01:04:47,900
U jekk ikollok dan, allura int
mhux ser ittella pornografija.

1208
01:04:47,900 --> 01:04:50,830
U naħseb li thats
Soluzzjoni soċjali verament sempliċi

1209
01:04:50,830 --> 01:04:56,060
għal kwistjoni teknika possibbilment kumplessa.

1210
01:04:56,060 --> 01:05:02,367
>> Allura dak imsemmi, aħna mibdula xi wħud
il-karatteristiċi madwar għall-iskola għolja.

1211
01:05:02,367 --> 01:05:04,200
Per eżempju, aħna ħa
partijiet out, għaliex aħna

1212
01:05:04,200 --> 01:05:06,370
dehret li l-ġenituri
se tikseb pissed off

1213
01:05:06,370 --> 01:05:09,280
jew huma biss ikissru kollha
il-partijiet KEG verament malajr,

1214
01:05:09,280 --> 01:05:10,744
u li terda għal kulħadd.

1215
01:05:10,744 --> 01:05:13,470
>> [Chuckles]

1216
01:05:13,470 --> 01:05:16,250
>> I do not know.

1217
01:05:16,250 --> 01:05:20,290
We deemphasize kuntatt
informazzjoni fl-iskola għolja.

1218
01:05:20,290 --> 01:05:22,746
Yeah.

1219
01:05:22,746 --> 01:05:24,120
UDJENZA: Kull dritt, aħna jispiċċaw hawnhekk.

1220
01:05:24,120 --> 01:05:26,220
Jekk għandek mistoqsijiet oħra, tħossok
liberu li tinżel u kellem lit-Mark.

1221
01:05:26,220 --> 01:05:27,120
Grazzi ħafna.

1222
01:05:27,120 --> 01:05:28,036
>> Zuckerberg Mark: Yeah.

1223
