00:00:00,000 --> 00:00:08,630

2
00:00:08,630 --> 00:00:11,450
DAVID Malan: Hello, dinja, dan
huwa CS50Live, u boy, do we

3
00:00:11,450 --> 00:00:13,680
jkollhom episodju aqwa għalik illum.

4
00:00:13,680 --> 00:00:17,400
L-ewwel, ħarsa ġewwa lejn kif
Dropbox xogħlijiet, imbagħad mill-qrib

5
00:00:17,400 --> 00:00:20,230
tħares lejn ħamsters ċkejkna
tiekol burritos ċkejkna,

6
00:00:20,230 --> 00:00:24,870
u fl-aħħarnett, ħarsa wara l-kwinti ħarsa
fuq film ġdid CS50, il Persistenza.

7
00:00:24,870 --> 00:00:27,410
>> Iżda l-ewwel, Dropbox.com,
fejn kellimna

8
00:00:27,410 --> 00:00:30,770
vjaġġata f'San Francisco, California,
li jiltaqa 'mal eks kap CS50 tal

9
00:00:30,770 --> 00:00:34,390
sħabi tagħlim, Thomas Carriero
li tawna tour ta Dropbox

10
00:00:34,390 --> 00:00:37,919
u eżattament dak li huwa simili li
xogħol u, daresay, jgħixu hemmhekk.

11
00:00:37,919 --> 00:00:39,960
Issa aħna sib stabbiliti mhux biss
ma 'Thomas filwaqt li hemm,

12
00:00:39,960 --> 00:00:43,400
iżda wkoll mal-eks CS50 tal
sħabi tagħlim ras Alex Allain

13
00:00:43,400 --> 00:00:46,330
biex jitkellmu dwar il-garanzija
ħidma ta Dropbox.com

14
00:00:46,330 --> 00:00:48,190
u huwa mqassma arkitettura.

15
00:00:48,190 --> 00:00:49,571
Ejja tagħti ħarsa.

16
00:00:49,571 --> 00:00:52,570
THOMAS CARRIERO: Ninsab Thomas Carreiro
Jien inġinier software fuq Dropbox.

17
00:00:52,570 --> 00:00:54,150
ALEX ALLAIN: Ninsab Alex Allain.

18
00:00:54,150 --> 00:00:57,110
I am inġinier hawn fuq Dropbox.

19
00:00:57,110 --> 00:01:00,250
>> THOMAS CARRIERO: Yeah, so I kien
attwalment l-ewwel CF ras għall CS50

20
00:01:00,250 --> 00:01:02,600
meta David Malan ħadet f'idejha l-klassi.

21
00:01:02,600 --> 00:01:05,930
I kienet diġà ġiet tagħlim
CS50 għal żewġ semestri

22
00:01:05,930 --> 00:01:09,610
ma 'Mike Smith, li kien hemm
il-professur qabel hemmhekk.

23
00:01:09,610 --> 00:01:12,410
>> ALEX ALLAIN: So I
attwalment ma ħaditx CS50,

24
00:01:12,410 --> 00:01:17,960
imma jien ma TF darbtejn, darba bħala
TF regolari u mbagħad fis-sena anzjan tiegħi,

25
00:01:17,960 --> 00:01:21,431
I kien attwalment Kap TF ta '
CS50, li kien ta 'gost.

26
00:01:21,431 --> 00:01:23,430
THOMAS CARRIERO: Allura meta
David laħaq out lili

27
00:01:23,430 --> 00:01:27,740
dwar it-twaqqif Dropbox
fil-appliance CS50,

28
00:01:27,740 --> 00:01:30,890
I kien verament eċċitati, minħabba
għandna attwalment jkollu klijent Linux.

29
00:01:30,890 --> 00:01:35,180
Ħafna mill-utenti tagħna użu jew
Twieqi jew il-klijenti Macintosh,

30
00:01:35,180 --> 00:01:38,830
iżda l-Linux, Macintosh, u
Klijenti twieqi huma kollha, fil-fatt,

31
00:01:38,830 --> 00:01:39,880
simili ħafna.

32
00:01:39,880 --> 00:01:44,510
Allura dak li għamilna huwa aħna installat minn qabel
il-klijent Dropbox Linux fil-CS50

33
00:01:44,510 --> 00:01:48,920
appliance, u din tmur bħad
kollha ta 'utenti tagħna oħra Linux.

34
00:01:48,920 --> 00:01:51,130
>> ALEX ALLAIN: Allura l-
mod Dropbox xogħlijiet huwa

35
00:01:51,130 --> 00:01:57,510
runs bħala l-klijent fuq ħafna differenti
sistemi operattivi u apparat.

36
00:01:57,510 --> 00:02:00,464
Il-klijent desktop Drobox huwa
wieħed mill-aktar magħrufa sew,

37
00:02:00,464 --> 00:02:01,630
waħda mill-aktar interessanti.

38
00:02:01,630 --> 00:02:04,430
>> THOMAS CARRIERO: So Dropbox
bażikament jieħu kollha tal-fajls

39
00:02:04,430 --> 00:02:06,350
li inti tpoġġi fil-
folder, u biċċiet

40
00:02:06,350 --> 00:02:08,380
dawk il-fajls f'erba biċċiet megabyte.

41
00:02:08,380 --> 00:02:12,170
Allura aħna ser tagħti 100
megabyte fajl PDF, u aħna ser

42
00:02:12,170 --> 00:02:14,990
chunk fis-25 biċċiet erba megabyte.

43
00:02:14,990 --> 00:02:19,760
Dawk biċċiet huma mbagħad encrypted, u
allura aħna jibgħathom servers blokk tagħna.

44
00:02:19,760 --> 00:02:24,870
>> ALEX ALLAIN: Il-servers blokk huma
il-ħażna għall-blokki nfushom,

45
00:02:24,870 --> 00:02:28,490
u għalhekk kull blokk hija maħżuna fil-
l-server blokk mal-data

46
00:02:28,490 --> 00:02:32,490
u hash SHA-256 ta 'dak blokki.

47
00:02:32,490 --> 00:02:37,190
Li l-encryption bażika ħafna primitive
li tiġbor fil-qosor, f'xi sens,

48
00:02:37,190 --> 00:02:42,050
L-informazzjoni fi ħafna uniku
b'mod li l-uniku għal dak data.

49
00:02:42,050 --> 00:02:44,430
Inti tista 'upload l-
fajl sħiħ kollha f'daqqa,

50
00:02:44,430 --> 00:02:48,820
iżda jirriżulta jekk inti tagħmel
li ma 'fajls verament kbar,

51
00:02:48,820 --> 00:02:51,734
huma jieħdu żmien twil verament li
upload, u jekk ikollok nuqqas,

52
00:02:51,734 --> 00:02:53,650
int minn xortih u
ikollok biex jerġa.

53
00:02:53,650 --> 00:02:56,700
Dak li aħna mbagħad nagħmlu huwa we tell
server ieħor fis-sistema tagħna, liema

54
00:02:56,700 --> 00:03:00,555
nitolbu-server meta, l-
server metadata, ħej, dan huwa fajl

55
00:03:00,555 --> 00:03:03,110
u huwa magħmul mill-
lista li ġejja ta 'blokki.

56
00:03:03,110 --> 00:03:05,972
U aħna rrinunzjati l-hashes
biex tidentifika dawk il-blokki

57
00:03:05,972 --> 00:03:07,680
minflok uploading ri
il-blokk kollu.

58
00:03:07,680 --> 00:03:09,805
Il-server meta mbagħad kontrolli
mal-servers kbar,

59
00:03:09,805 --> 00:03:12,950
tiżgura l-blokki qegħdin hemm - jekk
l huma, perfetta, kollox huwa tajjeb.

60
00:03:12,950 --> 00:03:15,720
>> THOMAS CARRIERO: Meta aħna rridu
li, bażikament, niżżel il-fajl

61
00:03:15,720 --> 00:03:19,370
mill-internet, ejja ngħidu,
aħna ser titlob server meta l-ewwel,

62
00:03:19,370 --> 00:03:22,010
ħej, tista 'tgħidli dwar
fejn dan il-fajl ikun jinsab,

63
00:03:22,010 --> 00:03:25,430
u server meta se ngħid, oh, ukoll,
dan il-fajl huwa attwalment 25 erba megabyte

64
00:03:25,430 --> 00:03:26,804
biċċiet, u hawn huma.

65
00:03:26,804 --> 00:03:28,970
U allura aħna ser imorru għall block
server u aħna ser attwalment

66
00:03:28,970 --> 00:03:32,534
tniżżel kull wieħed minn dawk biċċiet, u mbagħad
aħna ser jirrikostitwixxu l-fajl minn hemm,

67
00:03:32,534 --> 00:03:33,950
u allura aħna ser tibda l-download.

68
00:03:33,950 --> 00:03:36,490
Yeah, hekk jittratta Dropbox
bl-iskala, bażikament,

69
00:03:36,490 --> 00:03:38,592
billi ħafna, sharding aggressivi ħafna.

70
00:03:38,592 --> 00:03:40,300
ALEX ALLAIN: So sharding
huwa meta inti tieħu

71
00:03:40,300 --> 00:03:46,420
kollha tal-utenti fil tiegħek
istartjar jew il-kumpanija tiegħek,

72
00:03:46,420 --> 00:03:48,989
u forsi huma użati
li jkun fuq database waħda,

73
00:03:48,989 --> 00:03:51,530
u li xogħlijiet kbir sakemm inti
hit ċertu numru ta 'utenti,

74
00:03:51,530 --> 00:03:53,488
u verament dak li trid
tagħmel hu li ssib xi mod

75
00:03:53,488 --> 00:03:56,300
li jaqsam dawk madwar żewġ
databases jew forsi aktar minn tnejn -

76
00:03:56,300 --> 00:04:00,110
idealment, biżżejjed li inti tista '
għandhom kull utent fid-dinja.

77
00:04:00,110 --> 00:04:02,240
Allura meta inti Shard,
dak li għandek tagħmel hu li ssib

78
00:04:02,240 --> 00:04:05,740
xi mod biex tiddeċiedi
li database li jmorru

79
00:04:05,740 --> 00:04:09,150
li li ma tkunx teħtieġ
laqtu direttorju ċentrali,

80
00:04:09,150 --> 00:04:12,590
jew forsi huwa malajr ħafna, irħas
ħarsa-up f'dak direttorju ċentrali.

81
00:04:12,590 --> 00:04:16,129
>> THOMAS CARRIERO: Aħna qatt ma jkollhom
kollox maħżuna f'database waħda,

82
00:04:16,129 --> 00:04:17,920
minħabba li kważi
qatt tmur għall-iskala.

83
00:04:17,920 --> 00:04:22,770
Allura minflok, dak li nagħmlu huwa aħna ser jieħdu
ta 'dik l-informazzjoni, kollha tal-fajls

84
00:04:22,770 --> 00:04:24,590
huma kollha tal-metadata
u aħna ser Shard dan

85
00:04:24,590 --> 00:04:27,740
madwar l-mijiet jew eluf
databases tal-loġika.

86
00:04:27,740 --> 00:04:31,780
Dan ifisser li meta għandna
jitlob għall-informazzjoni ta 'utent,

87
00:04:31,780 --> 00:04:35,560
aħna ser ewwel ngħidu, ħej, li database
hija informazzjoni dan l-utent maħżuna,

88
00:04:35,560 --> 00:04:39,820
u allura aħna ser bażikament użu li
deċiżjoni li jmorru isibu li database,

89
00:04:39,820 --> 00:04:42,830
u li fejn aħna ser tagħbija kollha
l-fajls jew l-metadata

90
00:04:42,830 --> 00:04:44,010
dwar il-fajls.

91
00:04:44,010 --> 00:04:46,750
Allura aħna jużaw ħafna sharding, iżda
sharding mhux dejjem biżżejjed.

92
00:04:46,750 --> 00:04:49,280
Inti fil-fatt bżonn cache a
ħafna tat-talbiet komuni,

93
00:04:49,280 --> 00:04:52,940
għaliex anki jekk database
mistoqsijiet jistgħu jkunu għaljin.

94
00:04:52,940 --> 00:04:55,620
Allura aħna wkoll jagħmlu progressiva
istrateġiji caching

95
00:04:55,620 --> 00:04:59,210
biex tiżgura li l-aktar komuni
talbiet huma pjuttost faċli biex tiġi kkalkulata,

96
00:04:59,210 --> 00:05:03,560
u bażikament, li jagħmilha ħafna
aktar mgħaġġel u jagħmilha xogħol fuq skala.

97
00:05:03,560 --> 00:05:06,400
Allura dak, fuq livell għoli ħafna,
tip ta 'kif Dropbox xogħlijiet.

fejn dan il-kwotazzjoni fuq il-websajt CS50 tal

00:05:14,455 --> 00:05:17,150
ġej minn, huwa attwalment Alex
li huwa l-awtur oriġinali.

103
00:05:17,150 --> 00:05:20,160
Issa, taħdit ta 'Dropbox, I reċentement
irċieva din email minnhom

104
00:05:20,160 --> 00:05:23,199
fl-inbox tiegħi - Hi, David, inti tista '
tinnota li xi wħud links maqsuma tiegħek

105
00:05:23,199 --> 00:05:25,240
ma jkunux qed jaħdmu, u aħna
riedu jilħqu lilek

106
00:05:25,240 --> 00:05:27,237
personalment let you know għaliex.

107
00:05:27,237 --> 00:05:28,320
Ukoll x'hemm rabta kondiviża?

108
00:05:28,320 --> 00:05:31,580
Ukoll, jekk inti stajt użati Dropbox lil hinn
sempliċement iffrankar kodiċi sors tiegħek ġewwa

109
00:05:31,580 --> 00:05:33,288
ta 'l-appliance, inti
tista 'taf li inti

110
00:05:33,288 --> 00:05:36,100
jistgħu joħolqu links maqsuma minn
tikklikkja tipikament dritt fuq fajl

111
00:05:36,100 --> 00:05:37,875
u l-ikkupjar l-url lill clipboard tiegħek.

112
00:05:37,875 --> 00:05:40,750
Din ir-rabta kondiviża tista 'tfittex ftit
xi ħaġa bħal din, iżda minflok

113
00:05:40,750 --> 00:05:43,208
tal-sigriet kelma, hemm
attwalment xi ħaġa aktar cryptic

114
00:05:43,208 --> 00:05:45,990
hemm, bħal sekwenza ta '
każwali ittri u numri.

115
00:05:45,990 --> 00:05:49,910
Il-benesseri idea li I issa jistgħu email
jew Gchat dan it-tip ta url lil habib,

116
00:05:49,910 --> 00:05:55,180
u hu jew hi jista 'jkollhom aċċess CS50.txt u
niżżlu fuq il-kompjuter tiegħu jew tagħha.

117
00:05:55,180 --> 00:05:59,220
U biss billi jkun jaf li url, jew
super, probabbiltà baxxa super, guessing

118
00:05:59,220 --> 00:06:02,720
li url, jista 'xi ħadd ieħor
attwalment aċċess għall-fajl.

CollaboristaBlog tagħhom

121
00:06:07,370 --> 00:06:10,770
li hemm attwalment ftit
theddid għal dan workflow partikolari.

122
00:06:10,770 --> 00:06:13,680
Jirriżulta li jekk inti aċċidentalment
tagħmel żball, kif I, franchement,

123
00:06:13,680 --> 00:06:17,140
għamlu fil-passat, u paste
a url bħal link Dropbox maqsuma,

00:06:17,140 --> 00:06:20,330
fis jkunx l-indirizz browser tiegħek
bar, iżda bħala isaffru hawn,

125
00:06:20,330 --> 00:06:22,980
bar tfittxija tiegħek, li
url, naturalment, huwa għaddej

126
00:06:22,980 --> 00:06:25,380
li għandhom jiġu sottomessi għal
search engine bħall-Google.

127
00:06:25,380 --> 00:06:28,450
Of course, Google mhux se
neċessarjament jirrikonoxxu dik ir-rabta kondiviża,

128
00:06:28,450 --> 00:06:30,366
u hekk int ser
nikseb tiftix aktar ġeneriku

129
00:06:30,366 --> 00:06:32,680
riżultati bħal rabta
li Dropbox.com innifsu,

130
00:06:32,680 --> 00:06:36,320
u f'dan il-każ, reklam, u
fil-fatt, reklami, potenzjalment,

131
00:06:36,320 --> 00:06:38,055
għall-kompetituri ta 'Dropbox.

132
00:06:38,055 --> 00:06:40,180
Fil-fatt, li kif Intralinks
ndunat dan - huma,

133
00:06:40,180 --> 00:06:44,540
wisq, kienu jmexxu AdSense
kampanja flimkien tal-kliem kjavi

134
00:06:44,540 --> 00:06:46,320
li Dropbox nfushom jistgħu jużaw.

135
00:06:46,320 --> 00:06:48,790
U hekk jekk aħna zoom fl fuq
ir-riżultati tal-qiegħ hawn,

136
00:06:48,790 --> 00:06:52,070
tkun taf tara li Inralinks għandha
din link għall-servizz tagħhom stess.

137
00:06:52,070 --> 00:06:55,130
Issa waħda mill-karatteristiċi ta '
Google u 'search engines oħra "

138
00:06:55,130 --> 00:06:59,860
kampanji ta 'reklamar huwa li meta
utent bħali clicks fuq din ir-rabta, issa,

139
00:06:59,860 --> 00:07:04,160
I am ser tkun żvelata l-url
li I ittajpjat fil-Google sabiex

140
00:07:04,160 --> 00:07:05,760
biex isibu dawn ir-riżultati tat-tiftix.

141
00:07:05,760 --> 00:07:07,760
L-idea hija li
kumpaniji jixtieq ikun jaf
