>> DAVID Malan: Dan huwa Sanders Teatru.

3
00:00:04,860 --> 00:00:07,290
Dan huwa fejn CS50 tal-lekċers huma miżmuma.

4
00:00:07,290 --> 00:00:09,090
Grazzi tant għall ġejjin għall-kampus.

5
00:00:09,090 --> 00:00:10,610
Nistgħu tibda bil introduzzjonijiet?

00:00:19,190 --> 00:00:21,840
>> DAVID Malan: U dak li ġġib inti hawn
llum b'mod partikolari minn tant 'il bogħod?

12
00:00:21,840 --> 00:00:23,174
>> JACK: Eh, għal żjara ta 'Boston.

13
00:00:23,174 --> 00:00:23,840
DAVID Malan: OK.

14
00:00:23,840 --> 00:00:27,030
AMY: Kif tkun CS50 evolviet
kif inti stajt ġiet tagħlim dan?

15
00:00:27,030 --> 00:00:31,180
DAVID Malan: Huwa definittivament gotten
aktar drammatika matul is-snin.

16
00:00:31,180 --> 00:00:34,110
Imxejna ġiet iffilmjar mill-2007, hekk
inti tista litteralment tmur lura fil-ħin

17
00:00:34,110 --> 00:00:37,680
u jaraw aħħar snin, l-ewwel
lectures b'mod partikolari.

18
00:00:37,680 --> 00:00:41,550
U naħseb li l-ewwel lecture fi
2007 huwa pretty ħafna me joħorġu

19
00:00:41,550 --> 00:00:45,370
quddiem tal-klassi
qal bonjour, dan huwa CS50.

20
00:00:45,370 --> 00:00:47,730
U aħna ħamiema fil-materjal tal-ġurnata.

21
00:00:47,730 --> 00:00:49,640
>> Kull dritt, hekk welcome
Computer Science

22
00:00:49,640 --> 00:00:51,950
50: Introduzzjoni għall-
Computer Science One.

23
00:00:51,950 --> 00:00:55,620
Jisimni David Malan, u I se
jkun istruttur tiegħek dan is-semestru.

24
00:00:55,620 --> 00:00:56,940
>> Issa hemm mużika.

25
00:00:56,940 --> 00:00:58,270
Id-dwal jinżlu.

26
00:00:58,270 --> 00:00:59,730
Aħna drop down skrin kbir.

27
00:00:59,730 --> 00:01:02,145
Jistgħu jew ma jista 'jkun hemm
Muppets f'sena partikolari.

28
00:01:02,145 --> 00:01:07,725

29
00:01:07,725 --> 00:01:11,500
U huwa umoristiċi, għaliex dan
ikun kollu ġara mod ħafna

30
00:01:11,500 --> 00:01:13,670
matul is-snin, biss
ftit aktar kull sena.

31
00:01:13,670 --> 00:01:16,330
Iżda l-delta issa bejn il-
ewwel sena u l-aħħar sena

32
00:01:16,330 --> 00:01:20,540
huwa attwalment pjuttost atroċi kemm
l-ewwel ħames minuti differenti huma.

33
00:01:20,540 --> 00:01:25,530
>> AMY: Jien kurjuż, dak li tara
id-differenzi bejn il-EDX

34
00:01:25,530 --> 00:01:28,349
verżjoni u l-kors live?

35
00:01:28,349 --> 00:01:30,390
DAVID Malan: So curricularly
u teknoloġikament,

36
00:01:30,390 --> 00:01:35,670
CS50 fuq il-kampus u CS50x off
kampus huma fundamentalment l-istess.

37
00:01:35,670 --> 00:01:38,380
X'jagħmel differenti bejn il-
tnejn huwa l-livell ta 'appoġġ

38
00:01:38,380 --> 00:01:40,460
li aħna qed kapaċi li jipprovdu.

39
00:01:40,460 --> 00:01:44,590
Anke jekk CS50 għandu tim kbir ta '
madwar 100 fellows tagħlim, kors

40
00:01:44,590 --> 00:01:47,620
assistenti, myself, u
tim tal-produzzjoni tagħna,

41
00:01:47,620 --> 00:01:51,110
nistgħu biss bilkemm ilaħħqu
mal-700-istudenti fuq il-kampus

42
00:01:51,110 --> 00:01:55,925
u l-150 student iskola estensjoni
li huma lokali jew online infushom.

43
00:01:55,925 --> 00:01:59,690
>> U għalhekk għall CS50x, aħna sempliċiment ma jkollhomx
l-istruttura ta 'appoġġ tal-ħinijiet tal-uffiċċju,

44
00:01:59,690 --> 00:02:01,887
per eżempju, erba 'iljieli
ġimgħa għal bosta sigħat.

45
00:02:01,887 --> 00:02:05,220
JACK: U liema do you guys jitkellmu dwar fil
ħinijiet tal-uffiċċju li se jkunu differenti,

46
00:02:05,220 --> 00:02:08,063
jiġifieri, dak li għandek fuq lectures,
jew fuq sezzjonijiet, jew xorts?

47
00:02:08,063 --> 00:02:09,979
DAVID Malan: Fuq il-kampus
ħinijiet tal-uffiċċju huma verament

48
00:02:09,979 --> 00:02:12,922
opportunitajiet għall-
istudenti biex joħolqu mistoqsijiet

49
00:02:12,922 --> 00:02:16,130
waħda fuq waħda ma 'membru ta' l-tagħlim
persunal, jew saħansitra classmate ta 'tagħhom

50
00:02:16,130 --> 00:02:20,390
qrib, u ġeneralment wrestle ma bugs
li jkunu qed wara fil-kodiċijiet tagħhom.

51
00:02:20,390 --> 00:02:24,170
>> AMY: Naħseb Reddit tip ta 'jagħti
facsimile raġonevoli ta 'l-uffiċċju

52
00:02:24,170 --> 00:02:24,800
siegħa.

53
00:02:24,800 --> 00:02:25,740
>> DAVID Malan: Miftiehma, miftiehem.

54
00:02:25,740 --> 00:02:29,031
Stajt ġiet verament impressjonat, għalkemm, bil-
il-komunità Reddit u l-ġodda

55
00:02:29,031 --> 00:02:32,520
għall-grupp wisq u kemm
nies ħerqana u utli ġew.

56
00:02:32,520 --> 00:02:35,740
U Reddit definittivament jippresta ruħu
aħjar, naħseb, li istazzjonar tal-kodiċi

57
00:02:35,740 --> 00:02:37,620
u wara kamin diskussjonijiet.

58
00:02:37,620 --> 00:02:39,440
>> JACK: U taħseb
nies għandhom jippruvaw,

59
00:02:39,440 --> 00:02:41,460
jekk ikunu jafu li qed
tagħmel xi ħaġa ħażina,

60
00:02:41,460 --> 00:02:44,640
jew huwa simili li ħadthom implimentati
dan, bħal jintefqu wisq ħin fuq dan,

61
00:02:44,640 --> 00:02:49,080
allura dawn għandu jieqaf u jibda mill-ġdid,
jew tfittex għall-għajnuna, jew kif jekk dawn -

62
00:02:49,080 --> 00:02:51,140
>> DAVID Malan: Jieħu pawża minimament.

63
00:02:51,140 --> 00:02:55,530
Kultant, speċjalment għalija inqas
bħala livell ta 'tensjoni tiegħek tibda tiżdied,

64
00:02:55,530 --> 00:02:58,810
tibda hacking bogħod u l-ikkupjar u
pasta, jinsa dak li inti stajt diġà

65
00:02:58,810 --> 00:03:01,640
ippruvati, huwa biss ħin biex tmur
biex torqod, jew mur tieħu jog,

66
00:03:01,640 --> 00:03:05,250
jew mur doċċa, u biss
tip ta 'nikseb xi distanza.

67
00:03:05,250 --> 00:03:08,100
Dan ġara ħafna,
ħafna drabi lili fejn

68
00:03:08,100 --> 00:03:11,020
I ser tkun tinsab hemmhekk fis-sodda
anki, jew saħansitra sewqan biex jaħdmu

69
00:03:11,020 --> 00:03:13,320
jew il-mixi x'imkien, tip
ta 'debugging in my head.

70
00:03:13,320 --> 00:03:15,350
U jafu ladarba inti għandek li
distanza u ħafna stress inqas

71
00:03:15,350 --> 00:03:18,460
fuq spallejn tiegħek, I think tista 'inti
tirrealizza simili, oh, int idjota.

72
00:03:18,460 --> 00:03:23,220
Like I kien nesa li sejħa dan
funzjoni jew initialize xi varjabbli.

73
00:03:23,220 --> 00:03:27,350
