00:00:00,000 --> 00:00:00,127

2
00:00:00,127 --> 00:00:01,210
DAVID J. Malan: Kull dritt.

3
00:00:01,210 --> 00:00:02,160
Aħna lura.

4
00:00:02,160 --> 00:00:05,810
Allura, l-għan ta 'din is-sessjoni finali
huwa li jintroduċi kunċetti ftit aktar

5
00:00:05,810 --> 00:00:09,290
iżda wkoll kulħadd jingħata ċ-ċans
għall tip ta 'stretch swaba tiegħek

6
00:00:09,290 --> 00:00:11,270
u fil-fatt jagħmlu xi ħaġa
A ftit Hands-on.

7
00:00:11,270 --> 00:00:13,897
L-għan mhuwiex li jduru
lkoll fis iżviluppaturi tal-web

8
00:00:13,897 --> 00:00:16,230
bi kwalunkwe mezz imma verament ftit
li jtik togħma ta 'xi

9
00:00:16,230 --> 00:00:21,750
mill-constructs fundamentali ta 'dak li
tmur fil-programmazzjoni tal-web u llum web

10
00:00:21,750 --> 00:00:23,980
iżvilupp, sabiex il-
naħa statika ta 'things--

11
00:00:23,980 --> 00:00:26,660
ebda loġika, l-ebda programmazzjoni
lingwa, biss kontenut statiku.

12
00:00:26,660 --> 00:00:29,660
U se tagħtina l-opportunità
biex effettivament jaraw dak web server huwa,

13
00:00:29,660 --> 00:00:34,140
Ara dak file HTML huwa, tara liema
huwa HTTP huwa attwalment jservu up.

14
00:00:34,140 --> 00:00:38,600
Iżda qabel ma aħna adsa fi, kwalunkwe retrospettiva
mistoqsijiet dwar cloud computing

15
00:00:38,600 --> 00:00:43,922
jew garanzija jew xejn bejniethom?

16
00:00:43,922 --> 00:00:44,890
>> Nru?

17
00:00:44,890 --> 00:00:47,181
Kull dritt, ukoll, ejja
tagħmel dan, biss fil-każ

18
00:00:47,181 --> 00:00:49,680
il-proċess ta 'rreġistrar għal
xi ħaġa tieħu ftit minuti.

19
00:00:49,680 --> 00:00:51,221
Aħna ser ħalliha tagħmel dan fl-isfond.

20
00:00:51,221 --> 00:00:56,860
Jimxi 'l quddiem, jekk inti tista',
għal c9.io. dan il-URL here--

21
00:00:56,860 --> 00:01:02,810
Dan huwa ċittadin ta 'parti service--
pjattaforma bħala servizz, jekk inti will--

22
00:01:02,810 --> 00:01:05,190
li ser nistedinkom
biex jiffirmaw għal kont,

23
00:01:05,190 --> 00:01:08,650
u li għaddej biex jagħtuk kull wieħed minnkom
kont fil-sħaba hekk imsejħa

24
00:01:08,650 --> 00:01:11,330
fuq l-infrastruttura xi ħadd ieħor,
kumpanija msejħa Cloud9.

25
00:01:11,330 --> 00:01:13,350
Imma x'hemm sbieħ dwar
dan hija li dawn jagħtuk

26
00:01:13,350 --> 00:01:15,990
approssimazzjoni ta '
iżvilupp reali tad-dinja reali

27
00:01:15,990 --> 00:01:18,530
ambjent, għalkemm fil-
sħaba u fil-web browser,

28
00:01:18,530 --> 00:01:21,175
u aħna ser jużaw dan biex effettivament
esperiment daqsxejn llum.

29
00:01:21,175 --> 00:01:27,116

30
00:01:27,116 --> 00:01:30,260
U imbagħad imorru quddiem u biss jinnavigaw
tiegħek mod għall-proċess sign up

31
00:01:30,260 --> 00:01:32,630
jekk inti tista '.

32
00:01:32,630 --> 00:01:36,080
Allura aħna jiġri li tuża dan fil-klassi
I jgħallmu għal kulħadd ta 'l-istudenti tagħna,

33
00:01:36,080 --> 00:01:39,140
kemm fuq il-kampus u off issa, u
huwa sostitwit liema storikament

34
00:01:39,140 --> 00:01:41,390
Kien softwer inkella jitniżżel.

35
00:01:41,390 --> 00:01:44,620
Allura dak li kienu jiksbu aċċess għal
hija waħda mill dawn il-magni virtwali,

36
00:01:44,620 --> 00:01:46,460
essenzjalment, li jiena deskritt qabel.

37
00:01:46,460 --> 00:01:50,260
Allura din il-kumpanija Cloud9 probabbilment
kirjiet minn terz party-- tabilħaqq

38
00:01:50,260 --> 00:01:52,760
f'dan il-każ, Google-- kollu kemm hu
mazz ta 'magni virtwali

39
00:01:52,760 --> 00:01:56,500
li huma b'xi mod CHOP up fis
l-illużjoni ta 'servers individwali

40
00:01:56,500 --> 00:01:58,610
li kull wieħed minna għandu kontroll sħiħ fuq.

41
00:01:58,610 --> 00:02:01,640
Huwa pjuttost mhux preċiż, jiġifieri
li dawn qed magni virtwali,

42
00:02:01,640 --> 00:02:04,550
għalkemm, għaliex dak
Cloud9 effettivament juża

43
00:02:04,550 --> 00:02:07,570
hija teknoloġija kemmxejn aktar ġodda
imsejħa containers.

44
00:02:07,570 --> 00:02:13,150
U let me grab din l-istampa
hawn li żebgħa din l-istampa.

45
00:02:13,150 --> 00:02:16,540
>> Kontenitur huwa, jekk
inti mfakkra l-istampa

46
00:02:16,540 --> 00:02:19,900
minn qabel, ftit eħfef
piż minn magna virtwali.

47
00:02:19,900 --> 00:02:22,090
Fil-fatt, filwaqt li l-aħħar
ħin tkellimna dwar hemmhekk

48
00:02:22,090 --> 00:02:25,170
jkunu ta 'tħaddim
sistema, u bħala hypervisor

49
00:02:25,170 --> 00:02:28,260
u mbagħad sistema operattiva mistieden, guest
sistema operattiva, it-tħaddim mistieden

50
00:02:28,260 --> 00:02:30,940
sistema, fuq quċċata ta 'tiegħek
hardware fiżiċi,

51
00:02:30,940 --> 00:02:33,740
id-differenza ma 'din ġodda
teknoloġija, containers,

52
00:02:33,740 --> 00:02:37,290
huwa li dawn kollha b'xi mod jaqsmu
l-istess sistema operattiva.

53
00:02:37,290 --> 00:02:39,970
Iżda huma xorta joħolqu
l-illużjoni ta 'kulħadd

54
00:02:39,970 --> 00:02:44,590
wara stess esklużiv tiegħu jew tagħha
drittijiet amministrattivi u fajls

55
00:02:44,590 --> 00:02:45,400
fuq is-server.

56
00:02:45,400 --> 00:02:48,230
Iżda hemm inqas softwer fil
bejnek u l-hardware.

57
00:02:48,230 --> 00:02:52,260
Ir-riżultat ta 'liema huwa, fil
teorija, prestazzjoni ogħla,

58
00:02:52,260 --> 00:02:55,470
għaliex inti qed tuża jew
ħela anqas riżorsi

59
00:02:55,470 --> 00:02:57,360
fuq li l-hekk imsejħa saff Virtualization.

60
00:02:57,360 --> 00:02:59,420
Allura dan huwa msejjaħ
containers min-natura

61
00:02:59,420 --> 00:03:02,920
permezz ta 'teknoloġija msejħa Docker,
li huwa ferm dħul fis tagħha stess.

62
00:03:02,920 --> 00:03:05,086
U din hija xi ħaġa li
inġiniera fil-kumpanija tiegħek

63
00:03:05,086 --> 00:03:08,610
tista tip ta 'tip ta' jibda jitkellem
dwar hekk jekk dawn ma jkunux diġà,

64
00:03:08,610 --> 00:03:11,590
għalkemm hemm ċertament ebda
raġuni biex tiżdied fuq kull bandwagons.

65
00:03:11,590 --> 00:03:15,410
>> Allura ma 'dak imsemmi, liema
inti probabilment tara issa

66
00:03:15,410 --> 00:03:22,670
huwa skrin li jistenna ftit bħal dan.

67
00:03:22,670 --> 00:03:23,170
KOLLOX SEW.

68
00:03:23,170 --> 00:03:25,260
U biss isejħuli fuq jekk le.

69
00:03:25,260 --> 00:03:27,440
U jekk so-- jien ser jiġi maż jekk le.

70
00:03:27,440 --> 00:03:30,244
Jimxi 'l quddiem u kklikkja li l-kbar
flimkien biex joħolqu spazju ta 'xogħol,

71
00:03:30,244 --> 00:03:31,660
u tkun taf tara l-iskrin bħal dan.

72
00:03:31,660 --> 00:03:35,020
Tista 'sejħa tal-workspace
isem xi ħaġa li trid għal issa.

73
00:03:35,020 --> 00:03:38,660
U biss fil-fatt għas-sempliċità,
go and-- tajjeb, xi wħud minnkom

74
00:03:38,660 --> 00:03:39,660
diġà għandhom postijiet tax-xogħol.

75
00:03:39,660 --> 00:03:47,050
Sejħa hija tkun xi tkun inti want-- negozju,
Harvard, il-Ħamis, tkun xi tkun tixtieq.

76
00:03:47,050 --> 00:03:48,800
Inti ma għandekx bżonn deskrizzjoni.

77
00:03:48,800 --> 00:03:52,380
Tista 'tħalli privati, sakemm inti
diġà għandhom mazz ta postijiet tax-xogħol.

78
00:03:52,380 --> 00:03:55,280
Jekk inti qed sfurzati li jagħmilha pubblika,
li l-multa għal skopijiet lum.

79
00:03:55,280 --> 00:03:56,750
Hawnhekk, ukoll, hija waħda mill-upsells.

80
00:03:56,750 --> 00:03:59,939
Ikollok wieħed workspace privat billi
inadempjenza. Iżda jekk inti tixtieq aktar,

81
00:03:59,939 --> 00:04:00,980
inti għandek tħallas għal aktar.

82
00:04:00,980 --> 00:04:02,870
Inkella, huma seħħ inti
biex tagħmel pubblika xogħol tiegħek.

83
00:04:02,870 --> 00:04:05,600
Imma li l-multa, għaliex huma wkoll
mira dan fil-komunitajiet open-source

84
00:04:05,600 --> 00:04:07,700
biex jinkoraġġixxu lin-nies
fil-fatt jikkollaboraw.

85
00:04:07,700 --> 00:04:10,699
>> U l-aħħar ħaġa li l-importanti,
għalkemm, huwa, wara li inti tagħżel isem

86
00:04:10,699 --> 00:04:17,140
u wara li inti tagħżel privata jew pubblika,
ikklikkja HTML5, l-ikona oranġjo kbar

87
00:04:17,140 --> 00:04:22,430
tieni mix-xellug, u
imbagħad ikklikkja Oħloq Workspace.

88
00:04:22,430 --> 00:04:24,580
U se probabbilment
tieħu minuta jew hekk,

89
00:04:24,580 --> 00:04:26,540
iżda inti ser ikollok mbagħad ikollhom
ambjent, ladarba inti

90
00:04:26,540 --> 00:04:30,544
tagħmel dan, li jistenna reminixxenti ta
dak li għandi fuq l-iskrin hawn issa.

91
00:04:30,544 --> 00:04:33,210
Iżda, għal darb'oħra, jista 'jieħu minuta
jew aktar biex tikseb dan l-iskrin

92
00:04:33,210 --> 00:04:34,770
ladarba inti ħadthom għafast Oħloq Workspace.

93
00:04:34,770 --> 00:04:37,936
Iżda biss timmarka me tul jekk inti tixtieq lili
biex tagħti ħarsa lejn xi ħaġa jew xi parir.

94
00:04:37,936 --> 00:04:40,191

95
00:04:40,191 --> 00:04:40,690
Kull dritt.

96
00:04:40,690 --> 00:04:42,390
Hekk jien ser isfond dan għal issa.

97
00:04:42,390 --> 00:04:44,260
Call me tul jekk inti jidhru li
xi diffikultajiet tekniċi.

98
00:04:44,260 --> 00:04:46,210
Iżda, għal darb'oħra, jista 'jieħu
Ftit ftit ta 'dak li tiftaħ.

99
00:04:46,210 --> 00:04:49,570
U ejja imorru quddiem u jitkellmu dwar dak li
fil-fatt ifisser li tagħmel paġna web,

100
00:04:49,570 --> 00:04:52,780
dak HTML huwa, u kif dan kollu
issa interconnects kif aħna qed jibdew

101
00:04:52,780 --> 00:04:54,730
li attwalment jużaw xi wħud mill-teknoloġija.

102
00:04:54,730 --> 00:04:58,310
Għalhekk jirriżulta li nista '
mur fuq Mac tiegħi ftit hawn,

103
00:04:58,310 --> 00:05:01,650
tiftaħ program sempliċi imsejjaħ
TextEdit, jew fuq il-Windows stajt

104
00:05:01,650 --> 00:05:04,480
xi ħaġa miftuħ imsejħa Notepad.exe.

105
00:05:04,480 --> 00:05:08,260
UI tista 'biss sempliċement tagħmel xi ħaġa
bħal this-- "bonjour, dinja."

106
00:05:08,260 --> 00:05:12,020
U mbagħad I tista 'tiffranka dan bħala
hello.txt Allura l-ebda magic hemmhekk.

107
00:05:12,020 --> 00:05:15,200
Dan għandu x'taqsam xejn ma 'web
programmazzjoni, x'taqsam xejn ma HTML.

108
00:05:15,200 --> 00:05:16,790
Just toħloq fajl test sempliċi.

109
00:05:16,790 --> 00:05:20,600
Iżda jirriżulta li web
-paġna huwa litteralment biss dik.

110
00:05:20,600 --> 00:05:24,020
Huwa sempliċi fajl test li fih it-test
li inti tista tip fuq it-tastiera tiegħek,

111
00:05:24,020 --> 00:05:30,070
iżda tipikament iżda mhux dejjem
jispiċċa meta ma txt iżda html jew .htm.

112
00:05:30,070 --> 00:05:32,050
U inti ma biss
tip kliem fil-fajl.

113
00:05:32,050 --> 00:05:35,280
Inti fil-fatt għandek tuża affarijiet imsejħa
tags jew, b'mod iktar ġenerali, xi ħaġa

114
00:05:35,280 --> 00:05:37,190
imsejħa lingwa markup.

115
00:05:37,190 --> 00:05:40,510
>> Hekk jien ser malajr ħafna tip
u mbagħad jispjegaw dan li ġej.

116
00:05:40,510 --> 00:05:42,290
Jien ser ewwel
din it-tip, li jgħid,

117
00:05:42,290 --> 00:05:45,730
ħej, browser, hawn taqa '
web page miktub fl HTML.

118
00:05:45,730 --> 00:05:51,850
U dawn iż-żewġ affarijiet flimkien jgħidu, ħej,
browser, dan li ġej huwa tabilħaqq HTML.

119
00:05:51,850 --> 00:05:55,790
Ħej, browser, hawnhekk jidħol l-
ras jew il-quċċata tal-paġna tiegħi.

120
00:05:55,790 --> 00:05:59,900
Ħej, browser, ġewwa tal-quċċata ta '
paġna tiegħi, poġġi titolu jiġifieri, "hello,

121
00:05:59,900 --> 00:06:01,610
-dinja. "

122
00:06:01,610 --> 00:06:08,370
Ħej, browser, wara l-kap ta 'my
paġna, hawnhekk jidħol l-korp tal-paġna tiegħi.

123
00:06:08,370 --> 00:06:12,170
U, ħej, browser, il-korp ta 'tiegħi
paġna għandha tgħid ukoll, "bonjour dinja."

124
00:06:12,170 --> 00:06:15,500
Allura dak li huma d-dettalji ewlenin hawn?

125
00:06:15,500 --> 00:06:17,960
Dan huwa x'hemm ġeneralment
imsejħa 'dikjarazzjoni tat-tip dok,

126
00:06:17,960 --> 00:06:20,190
u, franchement, huwa ftit
diffiċli li jimmemorizza dan fl-ewwel.

127
00:06:20,190 --> 00:06:21,481
Inti biss tip ta 'kopja' paste.

128
00:06:21,481 --> 00:06:23,760
Dan huwa l-mod formali
ta 'tgħid, ħej, browser,

129
00:06:23,760 --> 00:06:28,030
I am jużaw verżjoni HTML 5 li
ħareġ xi ftit reċentement.

130
00:06:28,030 --> 00:06:31,380
Huwa incantation maġika li xi
bnedmin b'sens fqira ta 'disinn

131
00:06:31,380 --> 00:06:33,640
iddeċieda li jpoġġi fil-
fuq nett tal-fajl.

132
00:06:33,640 --> 00:06:35,473
Anki jekk huwa
ftit arcane, li kollox

133
00:06:35,473 --> 00:06:38,250
dan means-- ħej, browser, hawn
tiġi ma verżjoni 5 tal HTML.

134
00:06:38,250 --> 00:06:41,741
>> Il-bqija ta 'dan kien magħna
għal xi żmien issa, storikament,

135
00:06:41,741 --> 00:06:44,740
iżda huwa kien qed jevolvi, u dan l-
probabilment ġew jkollna ftit aktar sempliċi.

136
00:06:44,740 --> 00:06:47,320
Avviż ftit karatteristiċi
ta 'dak li stajt enfasizzati.

137
00:06:47,320 --> 00:06:49,890
Hemm dawn l-affarijiet ma angolat
brackets---kategorija xellug

138

u l-parentesi dritt.

139

U tinnota s-simetrija hawnhekk.

140
00:06:52,490 --> 00:06:57,340
U mill simetrija, I mean, biss bħala I
jkollhom din tikketta bidu hawn jew ta 'lametta miftuħ

00:07:06,460 --> 00:07:07,360
HTML.

144
00:07:07,360 --> 00:07:09,360
U inti tista 'taħseb
dan bħala I kien każwali

145
00:07:09,360 --> 00:07:12,280
jipproponi qabel, ħej,
browser, hawnhekk jidħol xi HTML.

146
00:07:12,280 --> 00:07:16,060
U, bil-maqlub, ħej, browser, dan huwa
lilha għall-bidu HTML-- u t-tmiem.

147
00:07:16,060 --> 00:07:18,440
>> Sadanittant ħej, browser, hawn
taqa 'l-kap tal-paġna tiegħi.

148
00:07:18,440 --> 00:07:20,140
Ħej, browser, li lilha għall-ras.

149
00:07:20,140 --> 00:07:22,240
Ħej, browser, hawnhekk hija
il-korp tal-paġna tiegħi.

150
00:07:22,240 --> 00:07:24,020
Ħej, browser, thats it għall-korp.

151
00:07:24,020 --> 00:07:26,940
U ġewwa ta 'dan huwa xi
Test arbitrarja għal issa.

152
00:07:26,940 --> 00:07:30,520
U ġewwa tar-ras, sadanittant,
hija xi arbitrarja imma ttikkettati,

153
00:07:30,520 --> 00:07:34,410
biex ngħidu hekk, it-test li tgħid, it-titolu
tal-paġna tiegħi għandu jkun "bonjour, dinja."

154
00:07:34,410 --> 00:07:37,470
Issa, għal issa, inti tista '
jassumi li browsers

155
00:07:37,470 --> 00:07:41,762
għandhom only-- jew, pjuttost, paġni tal-web jkollhom
tnejn biss parts---ras u l-ġisem.

156
00:07:41,762 --> 00:07:44,220
U l-kap huwa ġeneralment biss
bħall-menu bar, l-għalf

157
00:07:44,220 --> 00:07:45,510
verament ftit fil-quċċata ħafna.

158
00:07:45,510 --> 00:07:48,910
U l-korp huwa l-imsaren tal-paġna,
kollox dak ir-rettangolu kbar

159
00:07:48,910 --> 00:07:50,239
li timla l-iskrin.

160
00:07:50,239 --> 00:07:51,780
Hekk jien ser jimxi 'l quddiem u jagħmlu dan.

161
00:07:51,780 --> 00:07:54,400
I se jimxi 'l quddiem u
ikklikkja Save, File Save.

162
00:07:54,400 --> 00:07:58,580
U jien ser tiffranka
dan bħala hello.html,

163
00:07:58,580 --> 00:08:00,870
u jien biss ser
poġġih fuq id-desktop tiegħi.

164
00:08:00,870 --> 00:08:03,520
U jien se jmorru
quddiem u kklikkja Save.

165
00:08:03,520 --> 00:08:05,806
U notice-- Mac tiegħi fil
anqas tkun yelling fil lili.

166
00:08:05,806 --> 00:08:07,180
Inti żgur li inti tixtieq li tagħmel dan?

167
00:08:07,180 --> 00:08:08,710
U jien se ngħid, iva, l-użu HTML.

168
00:08:08,710 --> 00:08:10,400
Naf aħjar f'dan il-każ.

169
00:08:10,400 --> 00:08:14,686
U issa jien se jmorru għall-desktop tiegħi
fejn għandi dan il-fajl f'daqqa.

170
00:08:14,686 --> 00:08:16,060
U jien ser double-click fuqha.

171
00:08:16,060 --> 00:08:18,268
U inti ser ikollok avviż li, billi
Konvenzjonalment, Chrome fetħu.

172
00:08:18,268 --> 00:08:19,996
Dak għax dan huwa
-browser default tiegħi.

173
00:08:19,996 --> 00:08:21,370
U hija biss jgħid, "bonjour, dinja."

174
00:08:21,370 --> 00:08:23,078
Iżda huwa jgħid "bonjour,
dinja "f'żewġ postijiet.

175
00:08:23,078 --> 00:08:23,979
Avviż ta 'fuq nett.

176
00:08:23,979 --> 00:08:25,020
Pjuttost diffiċli li nitilfu dak.

177
00:08:25,020 --> 00:08:26,180
Huwa kbir u ambizzjuz.

178
00:08:26,180 --> 00:08:30,690
U fejn ħaddieħor ma jidhirx
li jgħidu, "bonjour, dinja"?

179
00:08:30,690 --> 00:08:31,470
>> UDJENZA: Il tab.

180
00:08:31,470 --> 00:08:33,100
>> DAVID J. Malan: Yeah,-tab innifsu.

181
00:08:33,100 --> 00:08:35,159
Allura meta I qal il-kap ta 'l-
-paġna huwa kollox up top--

182
00:08:35,159 --> 00:08:36,367
u fil-fatt dan huwa t-titlu.

183
00:08:36,367 --> 00:08:37,710
Huwa biss fil-tab hawn.

184
00:08:37,710 --> 00:08:40,320
U nista 'tiġbed dan tab
barra sabiex ma ssirx konfużjoni bejn.

185
00:08:40,320 --> 00:08:43,360
Dan huwa biss tab waħda issa,
u tabilħaqq naraw "bonjour, dinja"

186
00:08:43,360 --> 00:08:45,970
up hawn u "bonjour, dinja" stabbiliti hawn.

187
00:08:45,970 --> 00:08:47,160
Allura pjuttost sempliċi.

188
00:08:47,160 --> 00:08:49,050
Imma hija wkoll pjuttost sempliċi.

189
00:08:49,050 --> 00:08:50,440
U, fil-fatt, I żżomjati fil.

190
00:08:50,440 --> 00:08:53,272
I tista 'tbiddel id-daqs tat-tipa biss
biex tkabbar l-aċċessibilità.

191
00:08:53,272 --> 00:08:56,830
Imma ejja issa jagħmlu xi ħaġa
ftit aktar interessanti.

192
00:08:56,830 --> 00:08:59,760
>> Jien ser go-- Whoops, let
me terġa 'lura għall-fajl test tiegħi.

193
00:08:59,760 --> 00:09:02,400
Jien ser lura lill tiegħi
fajl test, u jien ser

194
00:09:02,400 --> 00:09:06,320
li jbiddlu dan u jgħidu
"Bonjour, Disney World."

195
00:09:06,320 --> 00:09:07,970
Save.

196
00:09:07,970 --> 00:09:10,919
U mur lura għall tiegħi
browser u kklikkja Reload.

197
00:09:10,919 --> 00:09:12,710
U issa, naturalment, huwa
jgħid "Disney World."

198
00:09:12,710 --> 00:09:15,500
U jien ser zoom artifiċjalment
fi ftit hekk huwa faċli biex tara.

199
00:09:15,500 --> 00:09:19,012
Allura issa, sfortunatament, I tip ta 'tixtieq
to-- fatt, li l-karatteristika Mac.

200
00:09:19,012 --> 00:09:21,720
Irrid li ikklikkja fuq Disney World
u jmorru x'imkien simili disney.com,

201
00:09:21,720 --> 00:09:23,290
iżda li ma taħdimx.

202
00:09:23,290 --> 00:09:26,850
Allura Prinċipju bażiku tal-web huwa
hyperlinks, rabtiet li jmorru x'imkien ieħor.

203
00:09:26,850 --> 00:09:28,390
Allura kif nista 'nagħmlu dan?

204
00:09:28,390 --> 00:09:34,690
Well, I jistgħu biss jgħidu,
"Bonjour, http://www.disney.com."

205
00:09:34,690 --> 00:09:36,110
Ħlief dan.

206
00:09:36,110 --> 00:09:37,620
Rikarigu.

207
00:09:37,620 --> 00:09:39,400
Iżda dan ukoll, mhux clickable.

208
00:09:39,400 --> 00:09:42,930
U x'hemm sbieħ hawn, minkejja
dan mhux funzjonali għadhom,

209
00:09:42,930 --> 00:09:45,930
hija li jidher li l-
brawżer ma litteralment biss

210
00:09:45,930 --> 00:09:46,950
dak I għid li tagħmel.

211
00:09:46,950 --> 00:09:50,110
Mela jekk jien biss tip URL bħal dan,
huwa biss se urini l-URL.

212
00:09:50,110 --> 00:09:54,270
I bżonn jużaw tikketti jew Markup
lingwa li attwalment tell

213
00:09:54,270 --> 00:09:55,621
l-browser li tagħmel aktar.

214
00:09:55,621 --> 00:09:57,870
Hekk jien ser jimxi 'l quddiem u
tħassar dan għal mument.

215
00:09:57,870 --> 00:10:00,980
U jien se ngħid, ħej,
browser, bidu ankra hawn,

216
00:10:00,980 --> 00:10:02,650
link biex ngħidu hekk.

217
00:10:02,650 --> 00:10:07,500
U l-iper-referenza, id-destinazzjoni
ta 'dak ankra, għandu jkun dan il-URL.

218
00:10:07,500 --> 00:10:08,750
U avviż kwotazzjonijiet tiegħi.

219
00:10:08,750 --> 00:10:11,590
I jistgħu jużaw kwotazzjonijiet uniku, ukoll,
iżda inti għandek tkun konsistenti,

220
00:10:11,590 --> 00:10:14,270
u nixtieq ġeneralment biss użu
kwotazzjonijiet doppja li jżommha sempliċi.

221
00:10:14,270 --> 00:10:16,820
Avviż Jien ser tagħlaq il-lametta.

222
00:10:16,820 --> 00:10:21,160
U allura hawnhekk jien ser
jiġifieri, "Disney World."

223
00:10:21,160 --> 00:10:26,890
U issa I bżonn xi symmetry--
parentesi miftuħa, / a, parentesi magħluqa.

224
00:10:26,890 --> 00:10:28,090
>> Allura dak li I introdotti?

225
00:10:28,090 --> 00:10:30,100
Aħna kellna xi tags ftit diġà.

226
00:10:30,100 --> 00:10:32,410
HTML, Kap, it-Titolu, Korp,
huma tikketti kollha, biex ngħidu hekk,

227
00:10:32,410 --> 00:10:34,280
mal-kontropartijiet miftuħa u magħluqa.

228
00:10:34,280 --> 00:10:36,530
Iżda avviż, dan huwa tip
ta fundamentalment differenti.

229
00:10:36,530 --> 00:10:39,140
Dan huwa dak li aħna ser sejħa
HTML attribut.

230
00:10:39,140 --> 00:10:41,451
U attribut huwa
biss par ta 'valur ċavetta.

231
00:10:41,451 --> 00:10:43,950
Din hija ħaġa komuni fil
-Valur essenzjali kompjuter science-- par.

232
00:10:43,950 --> 00:10:45,770
Huwa tip ta 'l-għodda ta' l-kummerċ.

233
00:10:45,770 --> 00:10:47,040
A ewlenin u valur.

234
00:10:47,040 --> 00:10:49,390
A kelma u mbagħad ftit
kelma jew kliem ieħor.

235
00:10:49,390 --> 00:10:53,790
U f'dan il-każ, il-muftieħ huwa href,
u l-valur huwa dak URL sħiħ.

236
00:10:53,790 --> 00:10:57,890
U dak attribut ma huwa
tinfluwenza l-imġiba ta 'tag.

237
00:10:57,890 --> 00:11:01,010
U f'dan il-każ, għandna bżonn li jinfluwenzaw
l-imġiba tal-lametta ankra,

238
00:11:01,010 --> 00:11:04,140
għaliex għandna bżonn li jankra
din ir-rabta biex x'imkien.

239
00:11:04,140 --> 00:11:06,960
U kif inti tagħmel dan huwa
permezz ta 'l-attribut.

240
00:11:06,960 --> 00:11:08,970
>> Hekk jien ser jimxi 'l quddiem
u jiffrankaw l-fajl issa.

241
00:11:08,970 --> 00:11:11,300
Mur lura lill-browser tiegħi u rikarigu.

242
00:11:11,300 --> 00:11:14,580
U, voila, issa għandna l
bidu ta 'paġna web leġittimu.

243
00:11:14,580 --> 00:11:18,420
Super-sempliċi, imma jekk jien imbagħad jerġgħu jsiru fuq
avviż this-- fil-kantuniera qiegħ tax-xellug,

244
00:11:18,420 --> 00:11:19,830
huwa super-żgħar.

245
00:11:19,830 --> 00:11:21,730
Imma inti tara www.disney.com.

246
00:11:21,730 --> 00:11:27,076
U jekk jien ikklikkja, fil-fatt dan
whisks me bogħod biex disney.com.

247
00:11:27,076 --> 00:11:29,380
Issa, il-ħaġa kurjuż
hawnhekk hija li mhuwiex

248
00:11:29,380 --> 00:11:33,940
il best-- il-URL aktar kummerċjabbli, iżda
li l-multa minħabba dan il-fajl ma

249
00:11:33,940 --> 00:11:35,360
jeżistu fuq il-World Wide Web.

250
00:11:35,360 --> 00:11:39,740
Jeżisti bħala fajl lokali apparentement
Utenti tiegħi directory-- / jharvard--

251
00:11:39,740 --> 00:11:41,890
John Harvard-- / desktop.

252
00:11:41,890 --> 00:11:42,634
Iżda għandha URL.

253
00:11:42,634 --> 00:11:43,800
Hija biss jiġri li jkun lokali.

254
00:11:43,800 --> 00:11:47,050
Sfortunatament, ħadd minn inti tista 'żżur
dan, għaliex jekk inti tip dan il-URL,

255
00:11:47,050 --> 00:11:49,980
youd tkun javżak-browser tiegħek,
tfittex għal fajl imsejjaħ hello.html

256
00:11:49,980 --> 00:11:50,772
fuq hard drive tiegħek.

257
00:11:50,772 --> 00:11:53,271
U, naturalment, sakemm inti ħadthom
ġew wara flimkien manwalment,

258
00:11:53,271 --> 00:11:54,530
mhuwiex ser jeżistu hemmhekk.

259
00:11:54,530 --> 00:11:55,190
>> Allura li l-multa.

260
00:11:55,190 --> 00:11:57,815
Aħna xorta jeħtieġu mod, finalment,
biex tikseb dan il-fajl fil-web,

261
00:11:57,815 --> 00:12:01,180
imma ejja tease apparti koppja ta
implikazzjonijiet ta 'sigurtà ta' dak li aħna biss

262
00:12:01,180 --> 00:12:04,850
raw u tie lura lill-ewwel
diskussjoni minn dalgħodu.

263
00:12:04,850 --> 00:12:08,200
Jirriżulta li, jekk
brawżer litteralment biss ma

264
00:12:08,200 --> 00:12:12,560
dak I għid li tagħmel, u jidher
li jkun il-każ li tag ankra huwa

265
00:12:12,560 --> 00:12:17,380
influwenzati mill-valur ta '
dan l-attribut imsejħa href

266
00:12:17,380 --> 00:12:20,810
iżda huwa juri din il
test, dan jidher

267
00:12:20,810 --> 00:12:26,520
li jimplika li stajt tpoġġi l-URL
kemm il-postijiet u mbagħad rikarigu

268
00:12:26,520 --> 00:12:29,100
u issa ara l-URL u jmorru l-URL.

269
00:12:29,100 --> 00:12:32,680
Avviż, jekk I imbagħad jerġgħu jsiru fuq il-qiegħ tax-xellug,
Jien fil-fatt ser xorta li disney.com.

270
00:12:32,680 --> 00:12:38,340
>> Mela jekk inti stajt qatt kien
phished-- P-H-I-S-H-E-D--

ma 'waħda minn dawk l-emails fittizji
minn bħall PayPal bank tiegħek,

272
00:12:42,820 --> 00:12:46,470
inti probabilment ħadthom gotten rabtiet ġewwa
tal-email li inti qed taqra dan

273
00:12:46,470 --> 00:12:49,970
jgħidlekx biex ikklikkja hawn biex tmur jikkonfermaw
-password tiegħek jew jikkonferma birthdate tiegħek

informazzjoni.

276
00:12:54,920 --> 00:12:57,625
Well, I tista 'tip ta' jieħu
vantaġġ ta 'dan, ma setgħetx I?

277
00:12:57,625 --> 00:13:01,240
Nista 'ngħid xi ħaġa
simili, www.paypal.com.

278
00:13:01,240 --> 00:13:11,340
U minflok ta disney.com, I
tista 'tmur lil, bħal, badguy.com.

279
00:13:11,340 --> 00:13:12,850
Rikarigu.

280
00:13:12,850 --> 00:13:16,620
U kemm huwa faċli li dupe,
speċjalment qarrej mhux tekniku

281
00:13:16,620 --> 00:13:20,649
jew cursorily qari
qarrej milli ikklikkja

I attwalment ma jridu jmorru badguy.com.

283
00:13:23,940 --> 00:13:25,398
I do not know dak li attwalment hemm.

284
00:13:25,398 --> 00:13:30,080
Allura paypal.com, avviż, huwa
dak li jgħid li għaddej biex,

285
00:13:30,080 --> 00:13:33,210
imma ovvjament, jekk I tfittex l isfel
Super baxx, huwa ftit blurry,

286
00:13:33,210 --> 00:13:34,230
iżda jgħid badguy.com.

287
00:13:34,230 --> 00:13:38,644
Dik hija l-unika tell dritt issa
li jien ser-post żbaljat.

288
00:13:38,644 --> 00:13:41,560
U meta għidt qabel li l-banek
verament ma għandhom iħeġġu jew ferrovija

289
00:13:41,560 --> 00:13:44,510
utenti fis rabtiet tikklikkja, dan
huwa biss wieħed manifestazzjoni ta 'dan.

290
00:13:44,510 --> 00:13:45,430
U li huwa sempliċi.

291
00:13:45,430 --> 00:13:48,120
Inti issa huma avversarju jekk
inti tagħmel xi ħaġa bħal din

292
00:13:48,120 --> 00:13:51,000
u tipprova trick-utent
fis jżuru l-website tiegħek.

293
00:13:51,000 --> 00:13:53,320
Iżda għal issa, aħna ser iżommu
affarijiet sbieħ u nodfa.

294
00:13:53,320 --> 00:13:55,640
Aħna qed tmur biex jimxi 'l quddiem
u kontrina dawn il-bidliet.

295
00:13:55,640 --> 00:13:56,530
Rikarigu-paġna.

296
00:13:56,530 --> 00:13:57,740
U mmur lura għall disney.com.

297
00:13:57,740 --> 00:14:00,660
>> Ejja naraw jekk aħna ma tistax tease
dan il bogħod minn xulxin ftit aktar.

298
00:14:00,660 --> 00:14:04,160
Allura "bonjour, Disney World."

299
00:14:04,160 --> 00:14:05,950
Jien se ngħid stabbiliti hawn.

300
00:14:05,950 --> 00:14:08,220
Forsi jien ser tagħmel xi kamra.

301
00:14:08,220 --> 00:14:12,730
"Nittamaw li inti tgawdi waqfa tiegħek!"

302
00:14:12,730 --> 00:14:13,830
Save.

303
00:14:13,830 --> 00:14:15,850
Rikarigu.

304
00:14:15,850 --> 00:14:19,010
Mhuwiex rea-- li mhux
dak I maħsuba, id-dritt?

305
00:14:19,010 --> 00:14:21,870
I mean, jekk jien trattament test tiegħi
fajl bħal word processor,

306
00:14:21,870 --> 00:14:24,894
dak li ma inti t-tama li jiġri hawn?

307
00:14:24,894 --> 00:14:27,060
Yeah, inħoss bħal hemm
għandu jkun waqfa linja hawn,

308
00:14:27,060 --> 00:14:28,799
għalhekk iħoss Buggy b'xi mod.

309
00:14:28,799 --> 00:14:31,090
Imma dak li attwalment intenzjonata,
minħabba eżatt bħal qabel,

310
00:14:31,090 --> 00:14:33,381
il-browser hija biss ser
tagħmel dak li għid li tagħmel.

311
00:14:33,381 --> 00:14:34,806
I ma qallek biex jinkiser linji.

312
00:14:34,806 --> 00:14:37,930
Stajt ma qallek li jiċċaqalqu isfel, anke
għalkemm, intuwittivament, inħoss bħal I ma.

313
00:14:37,930 --> 00:14:39,805
Għalhekk jirriżulta li għandna bżonn
Markup ftit aktar,

314
00:14:39,805 --> 00:14:41,390
u jien ser jiffissaw dan li ġej.

315
00:14:41,390 --> 00:14:46,160
Jien ser prefazju dan l-ewwel bonjour
ma 'dak li jissejjaħ il-paragrafu tag.

316
00:14:46,160 --> 00:14:48,920
U mbagħad jien ser jimxi 'l quddiem
u wrap din is-sentenza l-oħra

317
00:14:48,920 --> 00:14:54,370
fil-paragrafu lametta oħra, anki jekk
dawn qed paragrafi super-qasir.

318
00:14:54,370 --> 00:14:55,930
Issa jien ser jiffrankaw.

319
00:14:55,930 --> 00:14:57,160
Rikarigu.

320
00:14:57,160 --> 00:14:59,070
U issa għandna li
ispazju, u aħna xorta ta '

321
00:14:59,070 --> 00:15:01,680
għandhom l-semantika ta
żewġ paragrafi separati.

322
00:15:01,680 --> 00:15:05,290
>> Li kollox multa u tajjeb, iżda dan iwassal
Ikun sabiħ li jżid l-immaġini biex din il-paġna,

323
00:15:05,290 --> 00:15:08,710
hekk jien se jmorru tfittex
Mickey Mouse fuq Google Images.

324
00:15:08,710 --> 00:15:12,830
U biss għall-gost, jien
ser grab din id-dehra.

325
00:15:12,830 --> 00:15:15,350
Jien ser jimxi 'l quddiem issa u
grab l-URL tal din id-dehra,

326
00:15:15,350 --> 00:15:16,510
għalkemm hemm differenti
modi biex jagħmlu dan.

327
00:15:16,510 --> 00:15:18,520
Għal issa, jien biss ser kopja l-URL.

328
00:15:18,520 --> 00:15:24,770
Jien se jmorru lura fis-test tiegħi
fajl, u jien ser ngħid hawnhekk,

329
00:15:24,770 --> 00:15:31,160
img src = kwotazzjoni unquote
li URL, super-tul.

330
00:15:31,160 --> 00:15:34,580
U allura l-kunċett ta '
immaġini huwa xi ftit differenti.

331
00:15:34,580 --> 00:15:38,640
Hemm verament ebda idea ta 'tluq
immaġni u jispiċċa immaġni,

332
00:15:38,640 --> 00:15:40,630
bħal bidu tag tag ta tmiem.

333
00:15:40,630 --> 00:15:43,840
Allura iħoss ftit stramb li
lili semantikament biex tagħmel dan,

334
00:15:43,840 --> 00:15:45,390
li jkollhom tikketta close-immaġini.

335
00:15:45,390 --> 00:15:46,780
Mhuwiex żbaljata.

336
00:15:46,780 --> 00:15:48,840
Huwa perfettament korretta,
u huwa mħeġġeġ,

337
00:15:48,840 --> 00:15:50,870
imma hemm notazzjoni shorthand.

338
00:15:50,870 --> 00:15:53,780
Nista tip ta simultanjament
jiftaħ u jagħlaq l-istess tikketta,

339
00:15:53,780 --> 00:15:55,510
u li se jagħmlu l-browser kuntenti.

340
00:15:55,510 --> 00:15:56,950
Allura huwa biss ftit
aktar konċiż għal affarijiet

341
00:15:56,950 --> 00:15:59,408
li kunċettwali verament ma
jagħmel sens li jibdew u jintemmu.

342
00:15:59,408 --> 00:16:01,190
Huma biss qegħdin hemm, jew dawn mhux qed.

343
00:16:01,190 --> 00:16:06,020
>> Hekk jien ser jiffranka dan u jmorru lura
biex tiegħi "bonjour, dinja" paġna u rikarigu.

344
00:16:06,020 --> 00:16:09,880
U huwa ftit taħt kontroll,
minħabba li l-immaġni huwa attwalment

345
00:16:09,880 --> 00:16:12,210
ftit kbira, iżda li OK.

346
00:16:12,210 --> 00:16:13,710
I jistgħu resize dan fil-programm.

347
00:16:13,710 --> 00:16:14,900
Jew inti taf liema.

348
00:16:14,900 --> 00:16:17,350
Just biex juru, jien
ser attwalment ngħid

349
00:16:17,350 --> 00:16:21,760
li l-wisa 'dan il-ħaġa għandha
tkun biss 200 pixel, 200 tikek.

350
00:16:21,760 --> 00:16:24,360
Let me imorru quddiem u jiffrankaw
u rikarigu, u issa l-paġna

351
00:16:24,360 --> 00:16:25,690
jistenna ftit aktar raġonevoli.

352
00:16:25,690 --> 00:16:27,260
Iżda avviż-mudell.

353
00:16:27,260 --> 00:16:30,030
Well, stajt tip ta mgħallma inti kollha
ta HTML f'ċertu sens, għall-inqas

354
00:16:30,030 --> 00:16:33,531
kunċettwalment, minħabba li kull HTML huwa hu
dawn tags-- tikketti miftuħa, tikketti magħluqa,

355
00:16:33,531 --> 00:16:35,280
u attributi li
jimmodifikaw l-imġiba tagħhom.

356
00:16:35,280 --> 00:16:38,380
U, apparentement, kull
tikketta jista 'jkollhom żero jew wieħed

357
00:16:38,380 --> 00:16:43,005
jew tnejn jew aktar attributi, li kull waħda
li ma xi ħaġa ftit differenti.

358
00:16:43,005 --> 00:16:44,380
Issa, kif tkun taf liema jeżisti?

359
00:16:44,380 --> 00:16:46,800
Inti biss tisma 'xi ħadd
simili me jgħidlek dak li jeżisti,

jew int biss Google madwar għal tutorja
fuq HTML, u huwa verament huwa dan sempliċi.

361
00:16:50,860 --> 00:16:54,030
>> Tassew, meta I kien Undergrad
snin ilu u tgħallmu HTML,

362
00:16:54,030 --> 00:16:56,530
wieħed mill-tagħlim matematika tiegħi
assistenti biss jintefqu

363
00:16:56,530 --> 00:16:59,600
xi ftit ta 'żmien tutoring lili
simili għal nofs siegħa, siegħa,

364
00:16:59,600 --> 00:17:00,660
u mbagħad I kien fit-triq tiegħi.

365
00:17:00,660 --> 00:17:03,300
I kien fit-triq tiegħi lejn teħid
-websajts aktar hideous qatt,

366
00:17:03,300 --> 00:17:05,549
li, apparentement, jien ma
verament progress lil hinn.

367
00:17:05,549 --> 00:17:09,849
Iżda l-punt huwa li, ladarba inti
jifhmu dawn ideas-- sempliċi

368
00:17:09,849 --> 00:17:13,450
jekk arcane text-- iżda dawn sempliċi
ideat ta 'bidu maħsub

369
00:17:13,450 --> 00:17:15,960
u għeluq ta 'ħsieb, iż-żamma
kollox bilanċjat nicely,

370
00:17:15,960 --> 00:17:19,150

imġiba ta 'dak tikketta, li verament kollha

371
00:17:19,150 --> 00:17:20,079
hemm għaliha.

372
00:17:20,079 --> 00:17:28,140
U fil-fatt, jekk irridu issa mur

Hemm dan up hawn,

Apparentement, hemm xi

lingwa tal-paġna,

Hemm tag I ma

Huwa biss it-tip ta '

Hija tgħin ma SEO, jew

Iżda Div hija waħda għal
diviżjoni tal-paġna.

392
00:18:13,750 --> 00:18:16,680
Huwa simili rettangolu inviżibbli
jekk inti tip ta 'tixtieq li mentalment

Kwalunkwe kaxxa ta 'tfittxija int

Azzjoni.

402

L-azzjoni ta 'din il-formola, għal kwalunkwe
raġunijiet storiċi, huwa li URL.

403
00:18:37,660 --> 00:18:38,840
Metodu huwa "il-kariga."

404
00:18:38,840 --> 00:18:44,060
Jirriżulta li t-talbiet HTTP jistgħu jużaw
-verb "jiksbu," bħal rajna qabel,

405
00:18:44,060 --> 00:18:45,070
jew "posta."

406
00:18:45,070 --> 00:18:47,030
U se tara differenza
ta 'dan fil-mument.

407
00:18:47,030 --> 00:18:48,363
Ejja attwalment tara dak li din hija.

00:18:58,410 --> 00:19:02,441
U li kif dawn implimentata it-- ta '
tag li litteralment forma open parentesi.

415
00:19:02,441 --> 00:19:03,940
U mbagħad ejja tfittex xi ħaġa.

Marru għall-URL differenti.

423
00:19:20,484 --> 00:19:23,400
Allura, Stanford jżid xi magic
li dawn mhux qed tieħu lili biex l-URL

00:19:53,550 --> 00:19:54,660
Li ftit delikati biex tara.

438
00:19:54,660 --> 00:19:56,300
Let me terga 'lura għal dik
kwistjoni fi ftit minuti

439
00:19:56,300 --> 00:19:59,000
meta nħarsu lejn xi ħaġa imsejħa
folji CSS, jew stil cascading,

440
00:19:59,000 --> 00:20:02,500
u nistgħu nippruvaw tiddeduċi
kemm mill-paġna.

441
00:20:02,500 --> 00:20:08,090
Allura jekk aħna issa tagħti ħarsa lejn google.com,
ejja ara dak page tagħhom Dehra.

442
00:20:08,090 --> 00:20:09,840
Int tkun they're-- li l-ħelu illum.

443
00:20:09,840 --> 00:20:12,490

444
00:20:12,490 --> 00:20:12,990
KOLLOX SEW.

445
00:20:12,990 --> 00:20:13,690
Kollha isir.

446
00:20:13,690 --> 00:20:15,260
Kull dritt, hekk View Sors.

447
00:20:15,260 --> 00:20:19,590
Inti ser jaħseb Google
kodiċi tas-sors tassew sbieħ.

448
00:20:19,590 --> 00:20:24,970
Allura, apparentement, dak li qed jiġri hawn?

449
00:20:24,970 --> 00:20:27,880
U fil-fatt, dan lanqas ma huwa HTML.

450
00:20:27,880 --> 00:20:30,930
Din hija xi ħaġa imsejħa JavaScript.

451
00:20:30,930 --> 00:20:32,344
U ejja iżommu għaddejjin u għaddejjin.

452
00:20:32,344 --> 00:20:34,010
Jien lanqas biss jafu fejn il-paġna tibda.

453
00:20:34,010 --> 00:20:37,240
Jien ser tuża Kmand
F, miftuħa HTML parentesi.

454
00:20:37,240 --> 00:20:38,200
Kull dritt, hemm hu.

455
00:20:38,200 --> 00:20:44,150
Sibt il-bidu tal-paġna, u
hemm daqstant Jittieħed fil hawn.

456
00:20:44,150 --> 00:20:45,310
>> Dak li huwa attwalment jiġri?

457
00:20:45,310 --> 00:20:47,460
Ukoll, inti taf liema,
nistgħu tnaddaf dan up.

458
00:20:47,460 --> 00:20:52,109
Jekk jien minflok imorru għal dan Spezzjona
toolbar, din l-għodda dijanjostika speċjali,

459
00:20:52,109 --> 00:20:54,150
u mur mhux biex in-netwerk,
fejn inżommu għaddej illum,

460
00:20:54,150 --> 00:20:56,420
imma jekk immur Elementi,
x'hemm tassew sbieħ

461
00:20:56,420 --> 00:20:59,990
hija li browser għandha ħafna
għajnejn ħafna aħjar minn I do.

462
00:20:59,990 --> 00:21:02,670
U l-browser tista 'taqra
li mess ta 'paġna web,

463
00:21:02,670 --> 00:21:04,700
li HTML posta aħna biss
ħares lejn, u dan jista '

464
00:21:04,700 --> 00:21:08,340
parse jew jaqraw u
janalizzah u reformat

465
00:21:08,340 --> 00:21:09,910
fi sbieħ b'mod faċli għall-bniedem.

466
00:21:09,910 --> 00:21:11,740
Allura dak li jien jaraw issa
f'dan il-iskrin hawn

467
00:21:11,740 --> 00:21:15,470
taħt Elementi, l-istess kontenut eżatt,
iżda li ħadthom inċiża kollox,

468
00:21:15,470 --> 00:21:18,140
li ħadthom colorized, iżda
huwa l-istess test eżatt

469
00:21:18,140 --> 00:21:19,620
I jitniżżel mis-server.

470
00:21:19,620 --> 00:21:23,630
>> U x'hemm sbieħ issa huwa nista 'nara
fil-ġisem, għal avviż instance--,

471
00:21:23,630 --> 00:21:26,480
il-paġna għadha komposta
ta 'ftit ras u korp,

472
00:21:26,480 --> 00:21:28,660
u nista 'ġerarkiku adsa hawn.

473
00:21:28,660 --> 00:21:32,420
Avviż li Google jidher li
għal divs-- dan wieħed u dan wieħed.

474
00:21:32,420 --> 00:21:33,310
Nista 'tespandi dik.

475
00:21:33,310 --> 00:21:35,370
Hemm mazz sħiħ ta 'divs oħra.

476
00:21:35,370 --> 00:21:36,900
Allura huwa kumpless ftit.

477
00:21:36,900 --> 00:21:37,400
Imma stenna.

478
00:21:37,400 --> 00:21:40,970
Dan jidher tant aktar
tinqara, relattivament, minn dan.

479
00:21:40,970 --> 00:21:43,840
Għaliex huwa Google imbarazzanti
ruħha bi ftit jibgħat

480
00:21:43,840 --> 00:21:50,400
dan mess enormi ta 'kodiċi ta' xi
tip biss biex jiġu implimentati xi ħaġa

481
00:21:50,400 --> 00:21:53,640
li jistenna hekk sempliċi ewwel daqqa t'għajn?

482
00:21:53,640 --> 00:21:55,270
Simili, għaliex ma huma jżidu aktar spazji?

483
00:21:55,270 --> 00:21:56,811
Għaliex ma dawn hit Ikteb bħal I ma?

484
00:21:56,811 --> 00:21:59,110
Ħares kif tajba I kien
fil-kitba web page.

485
00:21:59,110 --> 00:22:00,680
I hit Ikteb hekk diliġenti.

486
00:22:00,680 --> 00:22:03,760
I inċiża hekk kollox
huwa so pretty u tinqara.

487
00:22:03,760 --> 00:22:08,463
Għaliex ma Google ma prattika l-istess?

488
00:22:08,463 --> 00:22:11,409
>> UDJENZA: [inaudible]

489
00:22:11,409 --> 00:22:12,305

490
00:22:12,305 --> 00:22:13,180
DAVID J. Malan: Tajba.

491
00:22:13,180 --> 00:22:14,270
ġust ħafna.

492
00:22:14,270 --> 00:22:16,650
Huma ma jkollhom xi
personalment fil-Google manwalment

493
00:22:16,650 --> 00:22:18,160
aġġornament tal-home page aktar.

494
00:22:18,160 --> 00:22:20,010
Mhuwiex 1999 jibqgħalu.

495
00:22:20,010 --> 00:22:21,140
Sabiex ikollhom is-software.

496
00:22:21,140 --> 00:22:25,397
Huma għandhom għodod oħra li
jiġġeneraw dinamikament dawn qed HTML.

497
00:22:25,397 --> 00:22:27,480
Naturalment, dan il-kodiċi innifsu
kienet miktuba mill-bnedmin,

498
00:22:27,480 --> 00:22:30,220
iżda r-realtà hija,
huwa pjuttost ġust li wieħed jgħid,

499
00:22:30,220 --> 00:22:33,340
l-browser ċertament ma
kura kif messy il-kodiċi hu.

500
00:22:33,340 --> 00:22:35,940
Iżda hemm xi saħansitra aktar
raġuni teknika konvinċenti

501
00:22:35,940 --> 00:22:42,580
li Google tiddistribwixxi HTML tagħhom
kodiċi f'tali sloppy, apparentement

502
00:22:42,580 --> 00:22:48,350
Mod kbira kollha ppakkjati flimkien
bi ftit way-- ftit li xejn

503
00:22:48,350 --> 00:22:51,274
fil-mod ta 'ifformattjar bħal I ma.

504
00:22:51,274 --> 00:22:52,570
>> UDJENZA: [inaudible]

505
00:22:52,570 --> 00:22:53,528
>> DAVID J. Malan: Faster?

506
00:22:53,528 --> 00:22:54,040
Għaliex?

507
00:22:54,040 --> 00:22:55,680
U dak did you say, Lydia?

508
00:22:55,680 --> 00:22:56,240
Faster?

509
00:22:56,240 --> 00:22:57,281
Għaliex aktar mgħaġġel?

510
00:22:57,281 --> 00:22:58,156
UDJENZA: [inaudible]

511
00:22:58,156 --> 00:23:00,522

512
00:23:00,522 --> 00:23:02,230
DAVID J. Malan: Hemm
ebda spazju biex jinqara.

513
00:23:02,230 --> 00:23:02,730
Yeah.

514
00:23:02,730 --> 00:23:04,560
Allura jaħsbu dwar dak li l-ispazju huwa.

515
00:23:04,560 --> 00:23:08,394
Allura kull karattru fuq it-tastiera jieħu
xi ammont ta 'spazju li jirrappreżenta,

516
00:23:08,394 --> 00:23:10,560
jew fiżikament, bhalu
jieħu l-ispazju ħafna,

517
00:23:10,560 --> 00:23:13,250
jew b'xi mod taħt il-
barnuża, li teħtieġ memorja.

518
00:23:13,250 --> 00:23:15,740
U bħala aside-- u aħna ser
jitkellmu aktar dwar dan tomorrow--

519
00:23:15,740 --> 00:23:19,930
kull karattru fuq it-tastiera
tipikament jeħtieġ 8 bits, jew byte wieħed.

520
00:23:19,930 --> 00:23:23,360
Allura mudell ta '8 żerijiet jew
dawk, jew biss 1 byte, kif aħna

521
00:23:23,360 --> 00:23:24,720
bnedmin tipikament ngħid.

522
00:23:24,720 --> 00:23:27,690
Allura dak żgħir, iżda
huwa għadu mhux żero.

523
00:23:27,690 --> 00:23:29,940
Huwa għadu xi ammont ta 'spazju.

524
00:23:29,940 --> 00:23:36,082
Mela jekk inġinier jew Google hits
-bar-ispazju darba biss, u jissoponi

525
00:23:36,082 --> 00:23:38,540
Google-- huwa super-popular--
jissoponi li biljun ruħ

526
00:23:38,540 --> 00:23:40,780
żur home-page tagħhom ta 'kuljum,
jew xi numru ta 'nies

527
00:23:40,780 --> 00:23:43,290
żur il-home page ta '
biljun darbiet kuljum,

528
00:23:43,290 --> 00:23:48,890
kemm bytes addizzjonali għandha dak
inġinier tas-softwer biss tiswa Google

529
00:23:48,890 --> 00:23:51,310
billi jolqot bar-ispazju tiegħu jew tagħha darba?

530
00:23:51,310 --> 00:23:52,692
>> UDJENZA: [inaudible]

531
00:23:52,692 --> 00:23:54,150
DAVID J. Malan: Mhux pjuttost dik ħażina.

532
00:23:54,150 --> 00:23:57,070
Just darba byte biljun.

533
00:23:57,070 --> 00:23:57,871
Allura a--

534
00:23:57,871 --> 00:23:59,120
UDJENZA: 8 biljun gigabytes.

535
00:23:59,120 --> 00:24:00,370
DAVID J. Malan: Mhux 8000000000.

536
00:24:00,370 --> 00:24:01,240
8 biljun bytes.

537
00:24:01,240 --> 00:24:02,410
Iżda 1 gigabyte.

538
00:24:02,410 --> 00:24:04,080
1 gigabyte ikun l-unità ta 'miżura.

539
00:24:04,080 --> 00:24:08,240
Jekk hu jew hi ma tnejn
spazji, 2 gigabytes.

540
00:24:08,240 --> 00:24:09,030
Tliet gigabytes.

541
00:24:09,030 --> 00:24:09,530
Dritt?

542
00:24:09,530 --> 00:24:11,860
Hija skali għaljin.

543
00:24:11,860 --> 00:24:16,150
U hekk f'każijiet bħall-Google,
li, mogħtija, huma l-każijiet estremi,

544
00:24:16,150 --> 00:24:21,450
hemm kwistjonijiet oħra li tinqala 'biss
billi jagħmlu deċiżjonijiet raġonevoli ħafna

545
00:24:21,450 --> 00:24:25,744
jew tieħu azzjonijiet tal-bniedem sempliċi ħafna,
minħabba li għandha dan l-effett eżaltat.

546
00:24:25,744 --> 00:24:27,660
Allura wieħed mir-raġunijiet
dan jistenna hekk kompressata

547
00:24:27,660 --> 00:24:30,660
huwa eżattament kif Rabat said-- kien
biss iġġenerat minn kompjuters xorta waħda.

548
00:24:30,660 --> 00:24:31,900
Allura l-ebda big deal.

549
00:24:31,900 --> 00:24:33,309
Ħalli l-browser figura hija out.

550
00:24:33,309 --> 00:24:35,350
Iżda huwa wkoll deliberatament
ma jkollu ħafna spazju,

551
00:24:35,350 --> 00:24:36,766
minħabba li l-ispazju mhux meħtieġ.

552
00:24:36,766 --> 00:24:38,250
U l-ispazju fil-fatt jiswa l-flus.

553
00:24:38,250 --> 00:24:40,670
>> Hija la ispejjeż ħin,
minħabba biss li timbotta

554
00:24:40,670 --> 00:24:44,670
li ħafna aktar dejta minn
kwartieri google.com s biss

555
00:24:44,670 --> 00:24:47,710
s'est li jieħdu xi ammont ta '
ħin, anki jekk huwa millisekondi

556
00:24:47,710 --> 00:24:51,190
jew mikrosekondi, imma li tammonta
fuq utenti tant, jew aktar probabbli,

557
00:24:51,190 --> 00:24:52,270
hija probabbilment jiswa l-flus.

558
00:24:52,270 --> 00:24:54,690
Google probabbilment jgħaqqad lill
xi ħadd ieħor fid-dinja, wieħed

559
00:24:54,690 --> 00:24:56,398
ta 'dawk peering
punti, u jekk ikollhom

560
00:24:56,398 --> 00:24:59,880
xi tip ta 'relazzjoni finanzjarja
li permezz tagħha l-ispejjeż dejta tagħhom flus,

561
00:24:59,880 --> 00:25:01,730
huma jistgħu wkoll
jimminimizzaw id-data kif ħafna

562
00:25:01,730 --> 00:25:04,530
dawn qed bżieq fuq
konnessjoni bl-internet tagħhom.

563
00:25:04,530 --> 00:25:07,630
>> Allura l-ħaġa umoristiċi, għalkemm, finalment,
jew forsi il-ħaġa rassikuranti,

564
00:25:07,630 --> 00:25:11,030
hija li anke jekk dan jistenna terriblement
kbira, fl-aħħar tal-ġurnata,

565
00:25:11,030 --> 00:25:16,750
huwa għadu l-istess prinċipji eżatt bħal
din il-paġna sempliċi ħafna hawnhekk ta 'HTML

566
00:25:16,750 --> 00:25:17,390
paġna.

567
00:25:17,390 --> 00:25:20,610
Hekk biss biex tqassar u sabiex inti
ikollhom verżjoni canonical jekk inti ma kinux

568
00:25:20,610 --> 00:25:25,900
li ġejja flimkien mill-għażla hawn, hawn
jista 'jkun l-aktar sempliċi ta' paġni tal-web,

569
00:25:25,900 --> 00:25:28,240
hekk xi ħaġa li jilagħbu bil forsi aktar tard.

570
00:25:28,240 --> 00:25:30,790
>> Ukoll, ejja jintroduċu
Koppja ta 'ideat oħra issa.

571
00:25:30,790 --> 00:25:33,420
Aħna waslet biex jintroduċu
xi ħaġa imsejħa tag stil.

572
00:25:33,420 --> 00:25:38,110
Nistgħu stylize din il-paġna
b'modi aktar interessanti.

573
00:25:38,110 --> 00:25:40,860
Allura billi HTML email
huwa kollha dwar l-immarkar up

574
00:25:40,860 --> 00:25:44,470
-data, it-tip ta tispeċifika lil
brawżer kif għandhom jistrutturaw id-data,

575
00:25:44,470 --> 00:25:48,110
fejn li tqiegħed lilha, CSS, jew
folji stil cascading,

576
00:25:48,110 --> 00:25:52,640
hija t-tieni lingwa li
ġeneralment gets mħalltin ma HTML

577
00:25:52,640 --> 00:25:55,670
kif aħna ser see-- iżda nistgħu nadif
li up fil-moment-- li jieħu

578
00:25:55,670 --> 00:25:59,850
dan l-mili finali, u dan stylizes dan.

579
00:25:59,850 --> 00:26:02,460
Jiġrilha l-kuluri biss id-dritt,
il-font daqsijiet biss id-dritt,

580
00:26:02,460 --> 00:26:03,860
l-ippożizzjonar biss id-dritt.

581
00:26:03,860 --> 00:26:06,510
Dan kollu dwar l-estetika
jew ifformattjar, mhux dwar

582
00:26:06,510 --> 00:26:08,330
id-data fundamentali innifsu.

583
00:26:08,330 --> 00:26:11,390
U l-eħfef mod biex juru
dan huwa forsi bl-eżempju.

584
00:26:11,390 --> 00:26:15,320
Hekk jien se jmorru fuq
għall-fajl tiegħi test sempliċi.

585
00:26:15,320 --> 00:26:17,970
U fi ftit mument, I ser
jimxu lilna permezz tal-proċess

586
00:26:17,970 --> 00:26:19,360
biex dan isir nfusna.

587
00:26:19,360 --> 00:26:23,310
>> Jien se jmorru lura għall-fajl tiegħi
hawn u rikarigu-paġna biss

588
00:26:23,310 --> 00:26:25,800
li tikkonferma dak li jidher qisu.

589
00:26:25,800 --> 00:26:27,190
Li meta aħna qed fil issa.

590
00:26:27,190 --> 00:26:31,170
Inħoss bħal gidjien jgawdu
wara xi kulur għal din il-paġna tal-web.

591
00:26:31,170 --> 00:26:34,480
Hekk jien se jmorru up hawn
fil-kap tal-paġna.

592
00:26:34,480 --> 00:26:38,130
U jien ser tagħmel stil, / stil.

593
00:26:38,130 --> 00:26:44,060
U allura ġewwa ta 'dan, jien ser
li tgħid il-korp ta 'page-- tiegħi

594
00:26:44,060 --> 00:26:46,870
u dan ifformattjar huwa, fl
Ewwel daqqa t'għajn, forsi ftit

595
00:26:46,870 --> 00:26:49,400
stramba imma konvenzjonali.

596
00:26:49,400 --> 00:26:55,010
Jien se ngħid li l-isfond
kulur ta 'din il-paġna għandha tkun ħadra.

597
00:26:55,010 --> 00:26:57,960
U dan huwa sfortunatament
tip ta 'mhux l-aħjar disinn.

598
00:26:57,960 --> 00:27:00,710
Avviż li qabel
fid-dinja tal-HTML,

599
00:27:00,710 --> 00:27:03,190
I qal li l-attributi
huma dawn il-pari b'valur ċavetta.

600
00:27:03,190 --> 00:27:05,760
Xi ħaġa huwa daqs kwotazzjoni
unquote "xi ħaġa."

601
00:27:05,760 --> 00:27:08,810
Fid-dinja ta 'CSS, li kienet
iddisinjat minn xi nies differenti,

602
00:27:08,810 --> 00:27:11,020
huma ddeċidew li, fil tagħhom
dinja, pari b'valur ewlenin

603
00:27:11,020 --> 00:27:13,920
Ikun kelma kolon xi ħaġa.

604
00:27:13,920 --> 00:27:15,220
Allura huwa l-istess idea, għalkemm.

605
00:27:15,220 --> 00:27:18,620
Huwa jassoċja lill valur
b'xi ċavetta li b'xi mod

606
00:27:18,620 --> 00:27:20,330
tinfluwenza l-imġiba ta 'din il-paġna.

607
00:27:20,330 --> 00:27:21,901
>> U inti tista 'probabbilment raden.

608
00:27:21,901 --> 00:27:24,150
Dak li huwa dan probabbilment se
biex nagħmlu anke jekk inti stajt qatt

609
00:27:24,150 --> 00:27:27,867
HTML jew CSS osservata qabel?

610
00:27:27,867 --> 00:27:29,450
UDJENZA: Ibdel il-kulur fl-isfond.

611
00:27:29,450 --> 00:27:30,560
DAVID J. Malan: Yeah,
jibdlu l-kulur fl-isfond.

612
00:27:30,560 --> 00:27:33,280
U speċifikament l-
kulur fl-isfond tal-ġisem.

613
00:27:33,280 --> 00:27:36,290
Iżda sakemm il-
korp għal issa huwa l-web

614
00:27:36,290 --> 00:27:38,870
page-- huwa l-unika ħaġa
taħt il-really-- bar titolu

615
00:27:38,870 --> 00:27:40,870
huwa probabbilment se
jinfluwenzaw l-istess ħaġa.

616
00:27:40,870 --> 00:27:41,430
Mela ejja ara.

617
00:27:41,430 --> 00:27:42,490
Ejja tiffranka din il.

618
00:27:42,490 --> 00:27:44,310
Mur hawn u rikarigu.

619
00:27:44,310 --> 00:27:46,140
Huwa pjuttost hideous.

620
00:27:46,140 --> 00:27:48,070
U x'inhu għaddej
hawnhekk hija effett sekondarju.

621
00:27:48,070 --> 00:27:49,850
I biss għażlet din id-dehra każwali.

622
00:27:49,850 --> 00:27:53,305
Għaliex huwa l-aħdar ma
permeating lura Mickey?

623
00:27:53,305 --> 00:27:54,180
UDJENZA: [inaudible]

624
00:27:54,180 --> 00:27:56,880

625
00:27:56,880 --> 00:27:57,880
DAVID J. Malan: Eżattament.

626
00:27:57,880 --> 00:28:01,750
Jirriżulta li l-immaġini, pretty
ħafna immaġini kollha li aħna jistgħu jużaw,

627
00:28:01,750 --> 00:28:03,670
huma kollha rectangles-- ta rettangoli.

628
00:28:03,670 --> 00:28:07,710
Anki jekk Mickey għandha xi kurvi
lilu nnifsu u għandha sfond,

629
00:28:07,710 --> 00:28:09,330
F'dan il-kuntest għandu jkun xi ħaġa.

630
00:28:09,330 --> 00:28:10,280
Għandu jkun abjad.

631
00:28:10,280 --> 00:28:11,910
Għandu jkun iswed jew xi ħaġa oħra.

632
00:28:11,910 --> 00:28:13,650
Jista 'jkun trasparenti.

633
00:28:13,650 --> 00:28:16,100
U fil-fatt, I jistgħu
miftuħa Mickey Mouse hawn

634
00:28:16,100 --> 00:28:18,590
fi programm imsejjaħ Photoshop
jew xi ħaġa simili

635
00:28:18,590 --> 00:28:21,176
u l-bidla kollha ta 'dak bajda
isfond trasparenti,

636
00:28:21,176 --> 00:28:22,550
hekk l-aħdar ikun shine permezz.

637
00:28:22,550 --> 00:28:25,980
Imma dak li xi ħaġa I bżonn
li jistaqsu nnifsi jew artist tal-grafika

638
00:28:25,980 --> 00:28:28,130
jew disinjatur fil tiegħi
kumpanija, per eżempju,

639
00:28:28,130 --> 00:28:31,490
li tagħmel, speċjalment peress li jien biss
mislufa dan wieħed mill-internet.

640
00:28:31,490 --> 00:28:33,030
Iżda hu għalhekk li dan qed jiġri.

641
00:28:33,030 --> 00:28:34,980
>> Allura dak li inkella jista rridu nagħmlu?

642
00:28:34,980 --> 00:28:41,040
Ukoll, aħna tista 'tixtieq li ngħid aħna
really hope inti tgawdi waqfa tiegħek.

643
00:28:41,040 --> 00:28:44,150
U għal enfasi, nixtieq
biex jagħmlu din b'saħħitha,

644
00:28:44,150 --> 00:28:48,310
u so I ser jgħidu miftuħa qawwija u
agħlaq qawwi u mbagħad jerġgħu jitgħabbew.

645
00:28:48,310 --> 00:28:50,320
U huwa diffiċli ftit
biex tara fuq il-projector

646
00:28:50,320 --> 00:28:53,250
imma forsi verament issa
jumps fil inti daqsxejn aktar.

647
00:28:53,250 --> 00:28:56,180
Allura inti tista 'żżid korsiv f'dan il-
mod, jiffaċċjaw kuraġġużi b'dan il-mod.

648
00:28:56,180 --> 00:28:57,500
Nistgħu jibdlu l-kuluri.

649
00:28:57,500 --> 00:29:01,610
Fil-fatt, biss għall kicks, jien
se jimxi 'l quddiem u jagħmlu dan.

650
00:29:01,610 --> 00:29:05,120
Jien ma verament simili kif tiegħi
paragrafi huma dan qrib flimkien,

651
00:29:05,120 --> 00:29:06,870
so I tista 'tagħmel xi ħaġa bħal din.

652
00:29:06,870 --> 00:29:13,310
Jien ser jgħidlek il-browser,
bidla kull punt tikketta li jkollhom,

653
00:29:13,310 --> 00:29:16,952
ejja say-- attwalment, inti taf liema,
ejja allinjata test-align, ċentru.

654
00:29:16,952 --> 00:29:19,410
U għal darb'oħra, Naf li dan biss
minħabba xi ħadd mgħallma lili

655
00:29:19,410 --> 00:29:21,118
jew Fittixt it up fil
referenza onlajn.

656
00:29:21,118 --> 00:29:22,450
So let me jiffranka dan l.

657
00:29:22,450 --> 00:29:25,070
U, ah, issa stajt
iċċentrata l-immaġini hemmhekk.

658
00:29:25,070 --> 00:29:28,490
U fil-fatt, inti taf liema, jekk
Nimxi immaġni tiegħi ġo paragrafu

659
00:29:28,490 --> 00:29:34,510
tag-- hekk tielet paragrafu,
anki jekk mhuwiex test.

660
00:29:34,510 --> 00:29:36,917
Ejja ħlief li u rikarigu.

661
00:29:36,917 --> 00:29:40,000
Issa il-paġna qed tibda tħares tip
of-- I mean, huwa għadu pjuttost ikrah,

662
00:29:40,000 --> 00:29:43,180
iżda mill-inqas jidher qisu I jintefqu
żewġ minuti minflok ta 'minuta waħda

663
00:29:43,180 --> 00:29:43,950
tagħmilha.

664
00:29:43,950 --> 00:29:47,200
>> U għalhekk, inkrementalment, nistgħu nagħmlu
dawn il-bidliet estetiċi issa għall-paġna?

665
00:29:47,200 --> 00:29:50,860
Stajt ma tbiddlitx-data fil-
paġna għajr tiżdied il-kelma verament.

666
00:29:50,860 --> 00:29:52,650
Stajt miżjud metadata, jekk inti se.

667
00:29:52,650 --> 00:29:54,830
Ħej, browser, jagħmlu l-
kelma "tassew" kuraġġużi.

668
00:29:54,830 --> 00:29:56,940
Iżda d-data mhix b'saħħitha.

669
00:29:56,940 --> 00:29:57,830
Li metadejta.

670
00:29:57,830 --> 00:29:59,410
Id-data hija "tassew."

671
00:29:59,410 --> 00:30:02,200
Allura aħna xorta jkollhom xi wħud
l-istess kunċetti bħal qabel.

672
00:30:02,200 --> 00:30:05,990
Issa, naturalment, dan mhux fuq il-web,
hekk jien ser tagħmel pass finali hawn.

673
00:30:05,990 --> 00:30:10,300
>> Jien se jmorru għall hello.html
u biss jenfasizzaw u kopja din il.

674
00:30:10,300 --> 00:30:12,285
U issa jien ser
jmorru fis Cloud9, li

675
00:30:12,285 --> 00:30:13,910
I ser jimxu miegħek permezz fi ftit mument.

676
00:30:13,910 --> 00:30:17,080
U odds huma inti ser dalwaqt tkun, jekk
mhux diġà, bi skrin bħal dan.

677
00:30:17,080 --> 00:30:21,080
U let me biss jagħtuk malajr
tour ta 'dak Cloud9 fatt hu.

678
00:30:21,080 --> 00:30:26,590
Għalhekk għal darb'oħra sħaba 9 huwa
dan is-servizz sħaba bbażata fuq

679
00:30:26,590 --> 00:30:30,580
li jagħti lilek u lili l-illużjoni
ta 'wara tal-magni virtwali tagħna stess

680
00:30:30,580 --> 00:30:33,090
fil-sħaba, teknikament
kontenitur fil-sħaba,

681
00:30:33,090 --> 00:30:35,160
li għandna sħiħa
privileġġi amministrattivi għal.

682
00:30:35,160 --> 00:30:37,130
Allura fit-teorija, l-ebda waħda
ieħor fid-dinja għandha

683
00:30:37,130 --> 00:30:39,152
aċċess għall-iskrin jien
tħares lejn id-dritt issa,

684
00:30:39,152 --> 00:30:40,860
ħlief forsi l-poplu
li jmexxu s-sit,

685
00:30:40,860 --> 00:30:43,470
minħabba teknikament li jkunu
aċċess fiżiku u ibqa 'sejjer hekk.

686
00:30:43,470 --> 00:30:44,740
>> Allura dak li naraw f'dan l-ambjent?

687
00:30:44,740 --> 00:30:46,230
Jien ser zoom out,
għaliex dan huwa ftit żgħira.

688
00:30:46,230 --> 00:30:48,104
U let me punt fuq
hawn għal ftit mument.

689
00:30:48,104 --> 00:30:53,210
Fuq in-naħa tax-xellug tal tiegħi u tiegħek
iskrin, hemm fajl browser fuq ix-xellug.

690
00:30:53,210 --> 00:30:55,362
Allura simili fl-ispirtu
għal Mac OS u Windows.

691
00:30:55,362 --> 00:30:57,070
Dawn huma kollha ta 'l-
fajls fil-kont tiegħi.

692
00:30:57,070 --> 00:30:59,250
U fil-kontumaċja, jekk tiegħek
kont huwa bħall-mini,

693
00:30:59,250 --> 00:31:05,090
tkun taf tara jew hekk ara
helloworld.html u readme.md.

694
00:31:05,090 --> 00:31:07,950
Minn hawn fuq il-lemin, dan huwa
fejn fajls test tiegħi se jmorru.

695
00:31:07,950 --> 00:31:11,620
Jekk inti stajt qatt jintużaw Microsoft
Word jew notepad jew TextEdit,

696
00:31:11,620 --> 00:31:14,100
dan huwa kelma editjar tiegħi
ta 'fajls huwa se jmorru.

697
00:31:14,100 --> 00:31:16,540
U allura l-aktar arcane
Karatteristika ta 'dan l-ambjent

698
00:31:16,540 --> 00:31:20,100
li aħna mhux se verament bżonn li tintuża l
stabbiliti hawn jissejjaħ Tieqa Terminal.

699
00:31:20,100 --> 00:31:23,390
Jekk inti ħadthom użati DOS minn
imgħoddi, dan huwa l-Linux

700
00:31:23,390 --> 00:31:25,450
jew l-ekwivalenti Linux tal DOS.

701
00:31:25,450 --> 00:31:28,190
Huwa interface-- ibbażat fuq test
ebda klikks ġurdien, l-ebda jittrattienu.

702
00:31:28,190 --> 00:31:30,770
Kulma tista 'tagħmel huwa tip
kmandi, iżda dawk l-kmandi

703
00:31:30,770 --> 00:31:34,400
jista 'joħloq fajls, jimxu fajls, miftuħa
direttorji, direttorji qrib,

704
00:31:34,400 --> 00:31:35,740
tagħmel xi numru ta 'affarijiet.

705
00:31:35,740 --> 00:31:38,060
Iżda għal issa, aħna ser biss
jqattgħu ħin tagħna hawn.

706
00:31:38,060 --> 00:31:39,050
>> U hekk ejja tagħmel dan.

707
00:31:39,050 --> 00:31:41,008
Jekk int f'dan il-
ambjent, li għandek

708
00:31:41,008 --> 00:31:45,900
tkun jekk inti ħolqot workspace
diġà, imorru quddiem u biss jitla '

709
00:31:45,900 --> 00:31:48,690
File, New għal mument.

710
00:31:48,690 --> 00:31:51,740
U li se jtik ġdid
tab dritt hawn fin-nofs.

711
00:31:51,740 --> 00:31:54,250
UI just-- u ejja
imorru quddiem u tagħmel dan.

712
00:31:54,250 --> 00:31:59,910
Ejja imorru quddiem u issa do File, Save
u jimxi 'l quddiem u sejħa hija hello.html,

713
00:31:59,910 --> 00:32:02,740
ma għandhomx jiġu mfixkla ma '
helloworld.html, li

714
00:32:02,740 --> 00:32:06,910
daħal mal-kont tiegħek ħielsa ġdid,
li huwa biss fajl kampjun.

715
00:32:06,910 --> 00:32:11,020
Inti se tara li f'daqqa jidhru,
aktar probabbli fuq in-naħa tax-xellug,

716
00:32:11,020 --> 00:32:12,810
u l-tab xorta se tkun miftuħa.

717
00:32:12,810 --> 00:32:21,300
U let me ninkoraġġukom issa biex toħloqhom
dan il-fajl jew xi varjazzjonijiet tal-istess.

718
00:32:21,300 --> 00:32:24,607
U jekk inti ma tistax pjuttost tara fuq il-
iskrin, dan huwa identiku għall-pjastri

719
00:32:24,607 --> 00:32:26,190
li inti probabilment jkollhom fil tab ieħor.

720
00:32:26,190 --> 00:32:29,296
>> Allura fil-qosor, jagħmlu web page tiegħek l-ewwel,
ħlief, u mbagħad fi ftit mument,

721
00:32:29,296 --> 00:32:31,170
I ser nuruk kif inti
jistgħu attwalment tara din.

722
00:32:31,170 --> 00:32:32,970
Iżda l-bidla mill-inqas ħaġa waħda.

723
00:32:32,970 --> 00:32:35,400
Bidla helloworld li
xi ħaġa ta 'l-għażla tiegħek,

724
00:32:35,400 --> 00:32:39,821
hekk li int konvint li huwa tiegħek
fajl u mhux dak I biss maħluqa.

725
00:32:39,821 --> 00:32:40,320
Kull dritt.

726
00:32:40,320 --> 00:32:43,804
U meta int ready-- ebda
rush-- meta int lest,

727
00:32:43,804 --> 00:32:46,220
imorru quddiem u jiffrankaw l-fajl
ladarba inti ħadna dawn il-bidliet.

728
00:32:46,220 --> 00:32:49,540
U jekk inti ikklikkja l-
Mexxi buttuna top up, dan

729
00:32:49,540 --> 00:32:53,610
għandha tiftaħ ġdid tab li se jgħidulek
inti dak URL tista 'żżur fajl tiegħek fi,

730
00:32:53,610 --> 00:32:56,380
iżda jista 'jieħu mument biex
kwotazzjoni unquote "bidu Apache," li

731
00:32:56,380 --> 00:32:58,820
huwa l-isem tas-server tal-web.

732
00:32:58,820 --> 00:33:02,430
Hekk ikunu attenti biex jagħmlu eżattament
x'hemm fil-fajl finalment.

733
00:33:02,430 --> 00:33:04,610
Allura issa dritt, jien ser zoom in.

734
00:33:04,610 --> 00:33:07,780
Jekk nibda ittajpjar
open-parentesi HTML, avviż

735
00:33:07,780 --> 00:33:09,650
huwa wassal lill lili biex jintemm ħsieb tiegħi.

736
00:33:09,650 --> 00:33:13,750
U jekk jien lest ħsieb tiegħi,
awtomatikament tagħti me l-tikketta għeluq.

737
00:33:13,750 --> 00:33:17,190
Iżda l-aspettattiva hija mbagħad I ser hit
Ikteb, u mbagħad jimxu ġewwa hemm

738
00:33:17,190 --> 00:33:21,180
u ma ras ġewwa u
imbagħad I do ġisem ġewwa.

739
00:33:21,180 --> 00:33:24,430
U huwa ftit stramb fl-ewwel,
għaliex dan qed jagħmel xogħol għalik,

740
00:33:24,430 --> 00:33:27,110
iżda tirrealizza li finalment
jiffranka keystrokes.

741
00:33:27,110 --> 00:33:30,500
U fil-fatt, karatteristika komuni ħafna ta '
ipprogrammar ambjenti dawn il-jiem

742
00:33:30,500 --> 00:33:33,260
kemm għall-iżvilupp tal-web bħal
dan u l-ipprogrammar attwali,

743
00:33:33,260 --> 00:33:36,960
li aħna ser nitkellmu dwar għada,
Huwa dawn awto-sħiħ il-karatteristiċi,

744
00:33:36,960 --> 00:33:39,710
affarijiet li ftit jippermettu
programmer jew disinjatur

745
00:33:39,710 --> 00:33:42,010
tip inqas keystrokes sa
twettaq l-istess ħaġa.

746
00:33:42,010 --> 00:33:43,176
Xi kultant huwa tajjeb, għalkemm.

747
00:33:43,176 --> 00:33:44,560
Kultant huwa biss annoying.

748
00:33:44,560 --> 00:33:49,290

749
00:33:49,290 --> 00:33:54,010
U, għal darb'oħra, ladarba inti ħadthom traskritta
l-slide jew xi varjant tagħha,

750
00:33:54,010 --> 00:33:57,360
inti tista 'ikklikkja l-buttuna Run top up.

751
00:33:57,360 --> 00:33:59,910
U mbagħad fil-qiegħ
tieqa, inti ser tkun infurmata

u oħrajn.

755
00:34:11,480 --> 00:34:14,580
Kull dritt, hekk, let me-- xi mistoqsijiet?

00:34:14,580 --> 00:34:19,460
Kwalunkwe mistoqsijiet oħra dwar biss jkollna
dan il-ħidma qabel we jżid karatteristiċi?

00:34:19,460 --> 00:34:21,692
U let me tipproponi, biss
biex tikseb folks comfortable--

758
00:34:21,692 --> 00:34:24,400

Iżda biss hekk li folks wrestle
b'mill-inqas wieħed biex tagħmel-,

00:34:27,177 --> 00:34:28,510
Jien ser jduru fuq xi mużika.

761
00:34:28,510 --> 00:34:32,630
Jien ser tipproponi lista ta '
affarijiet li tista 'potenzjalment iżżid.

762
00:34:32,630 --> 00:34:34,086
U inti tista 'ċertament tuża Google.

763
00:34:34,086 --> 00:34:36,210
U għaliex ma we biss
jipproponi li inti tipprova ssolvi

764
00:34:36,210 --> 00:34:38,710
mill-inqas wieħed problema partikolari hawn.

765
00:34:38,710 --> 00:34:45,090
Allura f'termini ta 'tikketti,
let me użu mill-ġdid din il hawn.

766
00:34:45,090 --> 00:34:48,280
>> Attwalment, let me tpoġġi
dan fil-forma testwali.

767
00:34:48,280 --> 00:35:02,380
Ejja ngħidu li fost l-tags nistgħu
użu hawn huma xi tags hawn fuq.

768
00:35:02,380 --> 00:35:06,090
Rajna l-paragrafu tikketta.

769
00:35:06,090 --> 00:35:07,850
Issa li għaddej biex awto komplet.

770
00:35:07,850 --> 00:35:12,220
Paragrafu tikketta, il-lametta ankra.

771
00:35:12,220 --> 00:35:15,250
Ejja ngħidu li inti tixtieq li
jagħmel xi ħaġa akbar,

772
00:35:15,250 --> 00:35:19,480
sabiex inti tista 'like--
-tikketta medda jista 'jgħin.

773
00:35:19,480 --> 00:35:23,010
Ukoll, jista 'jkollok bżonn xi għajnuna
għal dak fi ftit mument.

774
00:35:23,010 --> 00:35:24,830
Rajna div.

775
00:35:24,830 --> 00:35:26,170
Int ser ikollok tara hemm tabella.

776
00:35:26,170 --> 00:35:27,928
Hemm xi ħaġa imsejħa tr, td.

777
00:35:27,928 --> 00:35:30,736

778
00:35:30,736 --> 00:35:32,860
Th, td.

779
00:35:32,860 --> 00:35:34,770
Come lura għal dak fil-mument.

780
00:35:34,770 --> 00:35:36,590
X'iktar jista 'jkun handy?

781
00:35:36,590 --> 00:35:38,310
Hemm qawwija.

782
00:35:38,310 --> 00:35:43,640
Hemm enfasi, jew pjuttost em.

783
00:35:43,640 --> 00:35:50,110
There's-- x'iktar
jista inti fancy hawn?

784
00:35:50,110 --> 00:35:51,930
Ukoll, aħna ser tagħti
tħares lejn dak flimkien.

785
00:35:51,930 --> 00:35:53,230
Forma, li aħna stajt tidher.

786
00:35:53,230 --> 00:35:54,130
Hemm formola.

787
00:35:54,130 --> 00:35:56,500
Hemm input u ftit oħrajn.

788
00:35:56,500 --> 00:35:58,924

789
00:35:58,924 --> 00:36:00,090
Kull dritt, hekk ejja tagħmel dan.

790
00:36:00,090 --> 00:36:02,330
Sabiex tirrispondi għal xi s Rabat
kwistjoni, let me ewwel

791
00:36:02,330 --> 00:36:05,020
biss tagħmel ċert li kulħadd huwa
kapaċi tikseb xogħol bonjour tagħhom.

792
00:36:05,020 --> 00:36:06,900
Imbagħad let me jintroduċu
koppja ideat oħra.

793
00:36:06,900 --> 00:36:09,209
Imbagħad aħna ser let folks ssolvi
xi problema waħedhom.

794
00:36:09,209 --> 00:36:11,500
Imbagħad aħna ser verament terga 'lura
għal dan il-kunċett ta 'formola,

795
00:36:11,500 --> 00:36:14,950
u aħna ser attwalment jerġa 'jimplimenta
flimkien l-interface front-end,

796
00:36:14,950 --> 00:36:16,450
biex ngħidu hekk, għall-Google innifsu.

797
00:36:16,450 --> 00:36:19,700
Aħna ser tuża Google bħala l-aħħar lura u ħalli
minnhom jagħmlu x-xogħol iebes, l-tiftix,

798
00:36:19,700 --> 00:36:22,760
iżda aħna ser jirrikreaw-tarf ta 'quddiem
ta 'Google u l-forma tat-tiftix

799
00:36:22,760 --> 00:36:24,520
li dawn ikollhom fuq home-page tagħhom stess.

800
00:36:24,520 --> 00:36:27,050
U hekk aħna ser terga 'lura għal
dawn it-tags fi ftit mument.

801
00:36:27,050 --> 00:36:30,270
>> Allura dan kien dak I
pproponiet ftit mument ilu.

802
00:36:30,270 --> 00:36:33,940
Aħna tista 'żżid l-stylization għal
paġna ġewwa ta 'dan il-lametta istil,

803
00:36:33,940 --> 00:36:36,950
u nistgħu stylize l-isfond
kulur, l-allinjament test,

804
00:36:36,950 --> 00:36:39,000
jekk huwa ċentru jew lemin jew xellug.

805
00:36:39,000 --> 00:36:41,630
Imma malajr ħafna inti
isibu jew web designer

806
00:36:41,630 --> 00:36:44,060
ssib li din l
isir ftit dens,

807
00:36:44,060 --> 00:36:48,330
għax int tagħmel x'hemm
imsejħa taħlit kontenut

808
00:36:48,330 --> 00:36:50,120
bi preżentazzjoni tiegħu.

809
00:36:50,120 --> 00:36:53,756
Inti taħlit data tiegħek
u l-estetika tagħha.

810
00:36:53,756 --> 00:36:56,380
U fil-fatt, jekk inti tikkunsidra
x'inhu jiġri fuq time--

811
00:36:56,380 --> 00:36:58,350
dan huwa żgħir ħafna
paġna tal-web, tal-kors.

812
00:36:58,350 --> 00:37:01,590
Imma jekk jien iżidu l-kontenut din il-paġna
u jien jżidu l-istil din il-paġna,

813
00:37:01,590 --> 00:37:04,650
il-paġna malajr ħafna gets
itwal u itwal u itwal.

814
00:37:04,650 --> 00:37:07,510
U ejja ngħidu li nixtieq
jkollhom it-tieni paġna tal-web li

815
00:37:07,510 --> 00:37:09,010
jaqsam xi wħud minn dawn l-attributi.

816
00:37:09,010 --> 00:37:12,350
Ejja ngħidu web page tieni tiegħi għall tiegħi
site-- wkoll, nixtieq ċentru kollox,

817
00:37:12,350 --> 00:37:14,960
u jien ukoll jridu kollox
bi sfond aħdar.

818
00:37:14,960 --> 00:37:17,940
Jien pretty ħafna se jkollhom
kopja u paste xi wħud minn dawn il-linji

819
00:37:17,940 --> 00:37:20,730
f'dak tieni fajl, li jħoss multa.

820
00:37:20,730 --> 00:37:22,030
Hija se ssolvi l-problema.

821
00:37:22,030 --> 00:37:26,060
>> Imma x'jiġri jekk irrid terz paġna
jew paġna 30 jew paġna 40?

822
00:37:26,060 --> 00:37:28,730
Issa jien ser tkun ikkupjar u
pasta ħafna kodiċi duplikat

823
00:37:28,730 --> 00:37:30,430
fil-fajls multipli.

824
00:37:30,430 --> 00:37:32,600
U hekk jissoponi li
I jiddeċiedu jew jien told,

825
00:37:32,600 --> 00:37:34,780
ħej, aħna mhux qed tuża
sfond aħdar aktar.

826
00:37:34,780 --> 00:37:36,380
Aħna ser tibda tuża oranġjo.

827
00:37:36,380 --> 00:37:38,690
What do għandek tibdel?

828
00:37:38,690 --> 00:37:42,900
Ukoll, inti għandek għall-bidla li l-istil
minn aħdar għal oranġjo fil-mod kif f'ħafna postijiet?

829
00:37:42,900 --> 00:37:44,920
Bħall 30 jew 40 postijiet.

830
00:37:44,920 --> 00:37:45,900
Huwa tedious.

831
00:37:45,900 --> 00:37:47,039
Huwa suxxettibbli għal żball.

832
00:37:47,039 --> 00:37:49,580
Hemm numru ta 'raġunijiet
fejn inti ma tkunx tixtieq li jinduċi

833
00:37:49,580 --> 00:37:51,840
dan it-tip ta 'uġigħ għalik innifsek.

834
00:37:51,840 --> 00:37:54,760
U għalhekk ma kienx ikun sbieħ
jekk aħna nkunu nistgħu nieħdu dak I biss

835
00:37:54,760 --> 00:37:58,240
jitqiegħdu bejn dawn iż-żewġ isfar
tags, dawn it-tags stil,

836
00:37:58,240 --> 00:38:04,050
fattur it out, u poġġi dak kollu tad tiegħi
stylization f'waħda fajl ċentrali waħda

837
00:38:04,050 --> 00:38:08,470
li kull 30 jew 40 ta 'fajls oħra tiegħi
jissellfu minn jew b'xi mod referenza,

838
00:38:08,470 --> 00:38:11,640
mhux b'differenza mill-netwerking
dijagrammi aħna kienu qed jagħmlu qabel?

839
00:38:11,640 --> 00:38:15,030
>> Mela jekk immur fil hawn, jien
ser attwalment jipproponi

840
00:38:15,030 --> 00:38:17,880
li aħna tissostitwixxi l
tikketta istil ma 'xi ħaġa

841
00:38:17,880 --> 00:38:21,620
imsejjaħ il-lametta rabta, li
huwa horribly, horribly imsemmi,

842
00:38:21,620 --> 00:38:24,370
għaliex inti ma jużawx l-
tag link biex joħolqu dak

843
00:38:24,370 --> 00:38:26,380
aħna bnedmin nafu bħala rabta fil-paġna tal-web.

844
00:38:26,380 --> 00:38:29,750
Għal dan, inti tuża liema tag?

845
00:38:29,750 --> 00:38:31,464
Kif taħseb li toħloq link fil-paġna tal-web?

846
00:38:31,464 --> 00:38:32,130
UDJENZA: Il a.

847
00:38:32,130 --> 00:38:34,870
DAVID J. Malan: Il a, jew ankra
tikketta, li marru għall Disney qabel.

848
00:38:34,870 --> 00:38:39,090
Il-lametta rabta hawnhekk huwa qal
this-- link għal fajl imsejjaħ

849
00:38:39,090 --> 00:38:44,350
styles.css, ir-relazzjoni li fiha
se tkun li huwa stylesheet tiegħi.

850
00:38:44,350 --> 00:38:48,290
Allura dan huwa wieħed mill-S fl
folji stil cascading CSS--.

851
00:38:48,290 --> 00:38:50,490
Stil sheet-- tnejn tas-snin S fl CSS.

852
00:38:50,490 --> 00:38:52,550
Cascading karta tal-istil.

853
00:38:52,550 --> 00:38:58,640
Dan biss ifisser, ħej, browser, mur
issib styles.css fuq is-server lokali

854
00:38:58,640 --> 00:39:01,870
u tużah bħala stylesheet tiegħek,
li jfisser ġewwa ta 'dan il-fajl

855
00:39:01,870 --> 00:39:05,310
se tkun kollha tal-
stylizations li aħna ħadthom biss isir.

856
00:39:05,310 --> 00:39:07,396
U iva, liema dan il-fajl
jista 'dehra hija din.

857
00:39:07,396 --> 00:39:10,020
U jien ser biss tagħmel dan huwa ta 'malajr
eżempju, għaliex aħna ma bżonn

858
00:39:10,020 --> 00:39:12,000
biex tikseb wisq fil-ħaxix ħażin hawn.

859
00:39:12,000 --> 00:39:17,840
Imma jekk jien Kopja ta 'din, dak jien tipproponi
hija li programmer toħloq fajl ġdid,

860
00:39:17,840 --> 00:39:24,450
pejst f'dawk lines--
whoops-- paste fil dawk il-linji,

861
00:39:24,450 --> 00:39:32,270
ħlief bħala styles.css, u mbagħad, b'mod
-fajl ieħor, iħassru kollha ta 'dak

862
00:39:32,270 --> 00:39:35,450
u tibdilha minflok
ma 'dan tag rabta.

863
00:39:35,450 --> 00:39:43,090
B'tali mod li jekk jien rabta href = "styles.css",
ir-relazzjoni għandha tkun "stylesheet"

864
00:39:43,090 --> 00:39:44,170
tag qrib.

865
00:39:44,170 --> 00:39:45,250
Isalvawh.

866
00:39:45,250 --> 00:39:47,000
Mur lura għall helloworld tiegħi.

867
00:39:47,000 --> 00:39:48,690
Rikarigu.

868
00:39:48,690 --> 00:39:51,290
>> Litteralment ma ġara xejn.

869
00:39:51,290 --> 00:39:54,710
Din hija ħaġa tajba, għaliex
ifisser huwa attwalment kollu tax-xogħol.

870
00:39:54,710 --> 00:39:58,860
Biex jipprova kemm, jissoponi nagħmel
typo, u I call dan il- "Styles.css"

871
00:39:58,860 --> 00:40:03,080
bil-kapital S, li hija
żbaljata, u mbagħad jerġgħu jitgħabbew.

872
00:40:03,080 --> 00:40:05,470
Issa inti tista 'tara hija biss ma taħdimx.

873
00:40:05,470 --> 00:40:06,362
Issa, għaliex?

874
00:40:06,362 --> 00:40:08,070
Ukoll, ejja jużaw
teknika mill-ewwel.

875

DAVID J. Malan: Huwa ma nstabx.

883
00:40:24,770 --> 00:40:25,680

Allura hemm ftit modi biex tagħmel dan.

974
00:43:59,360 --> 00:44:01,530
Stajt bħalissa restawrata
iskrin tiegħi għal dan id-daqs,

975
00:44:01,530 --> 00:44:04,310
għalkemm stajt żżomjati fl

biss hekk aħna għandna xi test li jaħdmu magħhom.

987
00:45:03,270 --> 00:45:06,720
U l-għan Victoria kien li

So I tista ', bħal qabel, mur fil hawn.

989
00:45:09,879 --> 00:45:11,170
U let me tagħmel dan il-mod id-dritt.

990
00:45:11,170 --> 00:45:13,253
Jien ser ikollhom rabta
tag li jindika fajl

991
00:45:13,253 --> 00:45:20,560
imsejħa "styles.css," ir-relazzjoni
li minnhom hija għal darb'oħra "stylesheet."

U mbagħad jien ser tiffranka dak
u jiftħu dan "styles.css."

ħila f'dan il-fajl CSS

994
00:45:28,940 --> 00:45:31,569
li attwalment jwarrab l-inadempjenza
estetika ta 'paġna web,

00:45:31,569 --> 00:45:33,860
u l-estetika default,
naturalment, huma pjuttost matt.

996
00:45:33,860 --> 00:45:36,943
Huwa tip ta 'daqs normali font, iswed
test, l-isfond abjad, u oħrajn.

997
00:45:36,943 --> 00:45:39,440
So jissoponi Irrid nagħmel
kollha ta 'dan it-test akbar.

998
00:45:39,440 --> 00:45:40,460
I jistgħu jagħmlu ftit affarijiet.

999
00:45:40,460 --> 00:45:43,750
Fil fajl styles.css tiegħi, jien
jista 'jgħid, inti taf liema,

1000
00:45:43,750 --> 00:45:46,950
japplikaw dan li ġej għall-
il-korp tal-paġna tiegħi.

1001
00:45:46,950 --> 00:45:51,390
Jimxi 'l quddiem u jagħmlu l-
daqs tat-tipa 24 punti,

00:45:54,130 --> 00:45:57,620
Let me jmorru lura għall-web tiegħi
paġna hawn u rikarigu,

1004
00:45:57,620 --> 00:45:59,640
u tista 'tara li
huwa diġà ferm akbar.

1005
00:45:59,640 --> 00:46:02,223
U nistgħu jiksbu ftit crazy,
bħad nistgħu fuq desktop--

1006
00:46:02,223 --> 00:46:03,670
jagħmilha 96 punti.

1007
00:46:03,670 --> 00:46:04,950
Rikarigu.

1008
00:46:04,950 --> 00:46:07,610
U huwa jkollna ftit
dens f'dan il-punt.

1009
00:46:07,610 --> 00:46:09,500
>> Imma I jista 'jkun ftit aktar preċiż.

1010
00:46:09,500 --> 00:46:14,530
Minflok li japplika din il-
stylesheet lill-korp tal-paġna tiegħi,

1011
00:46:14,530 --> 00:46:21,740
x'iktar jista jien japplikawh għad minflok,
liema tag ieħor li jista xorta

1012
00:46:21,740 --> 00:46:25,445
funzjoni fl-istess mod?

1013
00:46:25,445 --> 00:46:26,444
>> UDJENZA: Il-lametta p?

1014
00:46:26,444 --> 00:46:27,360
DAVID J. Malan: tag P.

1015
00:46:27,360 --> 00:46:29,350
Allura l-ras ma tkunx
korretta, għaliex ir-ras,

1016
00:46:29,350 --> 00:46:31,300
inti ma tistax fil-fatt
tikkontrolla l-estetika tal.

1017
00:46:31,300 --> 00:46:32,700
Hemm kemm test hemmhekk jew le.

1018
00:46:32,700 --> 00:46:36,760
Iżda lp tag-- nista adsa ftit
aktar fil-fond, biex ngħidu hekk, li l-paragrafu

1020
00:46:37,350 --> 00:46:41,600
U anke jekk kien hemm tlieta,
li perfettament multa, għaliex fil CSS,

1021
00:46:41,600 --> 00:46:44,900
meta I biss jgħidu "p," dan
tfisser japplikaw dawn li ġejjin

1022
00:46:44,900 --> 00:46:48,300
għal kull tabella li taqbel din il
selettur, is-selettur biss

1023
00:46:48,300 --> 00:46:49,430
huwa l-isem tal-lametta.

1024
00:46:49,430 --> 00:46:52,350
Allura fejn tara
"P" tapplika d-daqs tat-tipa,

1025
00:46:52,350 --> 00:46:55,222
u ejja jagħmilha aktar
raġonevoli again-- 24 punt.

1026
00:46:55,222 --> 00:46:56,930
U inti taf liema,
biss għal miżura tajba,

1027
00:46:56,930 --> 00:46:59,810
ejja jagħmlu l-kulur
biss aħmar għall-mument.

1028
00:46:59,810 --> 00:47:03,740
U issa jekk jien jerġgħu jitgħabbew, issa għandna
ara tliet paragrafi ikrah.

1029
00:47:03,740 --> 00:47:07,180
>> Imma issa jissoponi li jien sort
of-- Irrid li l-ewwel paragrafu

1030
00:47:07,180 --> 00:47:08,210
biex tiżdied fil-utent.

1031
00:47:08,210 --> 00:47:11,150
Ma rridx li jiżdied ftit
id-daqs tat-tipa ta 'kollox.

1032
00:47:11,150 --> 00:47:16,105
U hekk jien fil-fatt tixtieq li jidentifikaw jew
tiddistingwi minn fost dawn il-paragrafi.

1033
00:47:16,105 --> 00:47:18,730
Mela ejja jeħles mill-aħmar,
għaliex dan huwa biss tip ta 'tacky,

1034
00:47:18,730 --> 00:47:23,885
u ejja imorru quddiem u jagħmlu l-
daqs tat-tipa 12-il punt fil-kontumaċja,

1035
00:47:23,885 --> 00:47:26,260
sabiex inkunu qed lura għal xi ħaġa
ftit aktar raġonevoli.

1036
00:47:26,260 --> 00:47:29,190
U issa I biss tixtieq li jiżdied il-
daqs tat-tipa tal-ewwel paragrafu.

1037
00:47:29,190 --> 00:47:31,440
I tista 'tagħmel dan fi ftit
modi, iżda mod wieħed li l-

1038
00:47:31,440 --> 00:47:37,180
forsi l-aktar istruzzjoni fil-
mument huwa li tagħmel dan li ġej.

1039
00:47:37,180 --> 00:47:43,280
Let me imorru quddiem u jgħidu, dan
paragrafu għandha ID unika ta ' "l-ewwel."

1040
00:47:43,280 --> 00:47:45,000
I jistgħu sejħa dan xejn irrid.

1041
00:47:45,000 --> 00:47:46,874
I tista 'sejħa dan "foo"
jew xi kelma oħra,

1042
00:47:46,874 --> 00:47:49,290
imma jien ser jagħtuh xi
Isem semantikament sinifikanti

1043
00:47:49,290 --> 00:47:50,320
bħal "l-ewwel."

1044
00:47:50,320 --> 00:47:54,790
Dan huwa l-identifikatur uniku,
l-ID, għall-ewwel paragrafu tiegħi.

1045
00:47:54,790 --> 00:47:59,360
>> What I issa jistgħu jagħmlu fil stylesheet tiegħi
huwa jkun ftit aktar preċiż.

1046
00:47:59,360 --> 00:48:02,330
Minflok qal, japplikaw
dan li ġej lill-tikketta p,

1047
00:48:02,330 --> 00:48:04,890
Nista 'ngħid l-following--
japplikaw dawn li ġejjin,

1048
00:48:04,890 --> 00:48:11,000
jew tagħżel, l-element HTML
li għandha ID unika ta ' "l-ewwel."

1049
00:48:11,000 --> 00:48:12,350
What do Irrid li japplikaw għalih?

1050
00:48:12,350 --> 00:48:15,250
Daqs tat-tipa ta '24 punt.

1051
00:48:15,250 --> 00:48:16,640
So I għandhom żewġ seletturi issa.

1052
00:48:16,640 --> 00:48:19,690
Wieħed jagħmel dan kollu
punti 12-il punt.

1053
00:48:19,690 --> 00:48:24,960
Iżda dan wieħed, speċjalment peress niġu
second-- niġu aħħar fil-file--

1054
00:48:24,960 --> 00:48:27,090
dan għandu effett cascading.

1055
00:48:27,090 --> 00:48:30,200
Stajt biss magħmula kollha kemm tiegħi
tags paragrafu 12-point,

1056
00:48:30,200 --> 00:48:34,350
iżda dan issa kaskati u
jieħu prijorità fuq li għal kull element

1057
00:48:34,350 --> 00:48:38,800
fil-paġna, kull tabella fil-paġna li
ID unika huwa unquote kwotazzjoni "l-ewwel."

1058
00:48:38,800 --> 00:48:41,720
U l-hashtag f'dan il-kuntest
ifisser biss "identifikatur uniku."

1059
00:48:41,720 --> 00:48:43,750
Jien ma tqiegħed fil-fajl HTML.

1060
00:48:43,750 --> 00:48:46,880
I, minn hawn, biss jgħidu
kwotazzjoni unquote "l-ewwel."

1061
00:48:46,880 --> 00:48:48,470
>> So let me rikarigu.

1062
00:48:48,470 --> 00:48:49,919
U issa nara, ah, OK.

1063
00:48:49,919 --> 00:48:51,710
I mean, mhuwiex li
pretty, imma hija tip

1064
00:48:51,710 --> 00:48:53,600
ta bħall-daħla għal
ktieb jew xi ħaġa bħal dik,

1065
00:48:53,600 --> 00:48:55,100
fejn l-ewwel paragrafu huwa akbar.

1066
00:48:55,100 --> 00:48:57,933
Jista 'jkun saħansitra aktar preċiża ma
biss l-ewwel ittri, iżda mill-inqas

1067
00:48:57,933 --> 00:48:59,110
Stajt eżerċitat kontroll aktar.

1068
00:48:59,110 --> 00:49:04,760
Issa maybe-- forsi I tixtieq li tagħmel dan
kultant għal kwalunkwe raġuni,

1069
00:49:04,760 --> 00:49:09,010
u so I ma tridx dan
japplikaw biss HTML tag wieħed.

1070
00:49:09,010 --> 00:49:15,110
Pjuttost, ejja say-- ejja
wkoll jagħmlu dan li ġej.

1071
00:49:15,110 --> 00:49:18,810
Class = "importazzjoni."

1072
00:49:18,810 --> 00:49:23,970
Billi ID tintuża biex unikament
jidentifikaw ħaġa waħda, lametta waħda,

1073
00:49:23,970 --> 00:49:30,190
fil-paġna web tiegħek, klassi huwa maħsub li jkun
użati fuq kull numru ta 'elementi jew tikketti

1074
00:49:30,190 --> 00:49:30,950
fuq il-paġna web tiegħek.

1075
00:49:30,950 --> 00:49:31,710
Allura huwa li jistgħu jerġgħu jintużaw.

1076
00:49:31,710 --> 00:49:33,090
ID mhix jistgħu jerġgħu jintużaw.

1077
00:49:33,090 --> 00:49:34,450
A klassi hija li jistgħu jerġgħu jintużaw.

1078
00:49:34,450 --> 00:49:37,830
>> U inti taf liema, għal kwalunkwe
reasons-- filosofiku

1079
00:49:37,830 --> 00:49:40,180
Jien ma finitura tiegħi
thought-- jien ser ngħid

1080
00:49:40,180 --> 00:49:44,300
li l-ewwel paragrafu u l-
tieni paragrafu huma importanti.

1081
00:49:44,300 --> 00:49:48,600
Hekk jien ser tapplika l-klassi msejħa
"Importanti," li, jekk I ħlief fajl tiegħi

1082
00:49:48,600 --> 00:49:51,510
u rikarigu, m'għandha l-ebda
impatt funzjonali s'issa.

1083
00:49:51,510 --> 00:49:53,780
Imma stajt żied xi
metadejta għall-fajl,

1084
00:49:53,780 --> 00:49:56,610
tip ta 'xi ħaġa separata
mid-data ċentrali tal-fajl,

1085
00:49:56,610 --> 00:50:02,300
b'tali mod li issa fil stylesheet tiegħi, jekk I
minflok jgħidu ".important" - tafu,

1086
00:50:02,300 --> 00:50:07,110
xi ħaġa li huwa importanti, jien
ser jagħmlu font color, red--

1087
00:50:07,110 --> 00:50:09,930
jew pjuttost ma 'font color, biss kulur.

1088
00:50:09,930 --> 00:50:12,930
Hemm inkonsistenzi
fil CSS sfortunatament.

1089
00:50:12,930 --> 00:50:14,120
U rikarigu.

1090
00:50:14,120 --> 00:50:17,640
Issa avviż-ewwel
żewġ paragrafi huma ħomor

1091
00:50:17,640 --> 00:50:20,880
iżda mhux it-tielet, minħabba I biss
applikat il-klassi ta ' "importanti"

1092
00:50:20,880 --> 00:50:25,020
l-ewwel tnejn minn dawn l-affarijiet.

1093
00:50:25,020 --> 00:50:28,030
>> Għalhekk fl IDs, inti għandek il-ħila
biex jispeċifikaw b'mod preċiż ħafna.

1094
00:50:28,030 --> 00:50:30,110
Ma 'klassijiet, għandek użu mill-ġdid.

1095
00:50:30,110 --> 00:50:33,800
Iżda fiż-żewġ każijiet, avviż-
tip ta 'prinċipju tajba disinn

1096
00:50:33,800 --> 00:50:39,072
fejn I fatturati out kollha ta 'l-
estetika għall-fajl styles.css tiegħi.

1097
00:50:39,072 --> 00:50:40,280
B'hekk m'hemm l-ebda messiness hawn.

1098
00:50:40,280 --> 00:50:44,490
M'hemm l-ebda referenza ta 'aħmar jew
skuri-faċċata jew id-daqs tat-tipa f'dan il-fajl.

1099
00:50:44,490 --> 00:50:49,430
Pjuttost Għandi semantikament,
sinifikattiv karatterizzat data tiegħi bħala,

1100
00:50:49,430 --> 00:50:51,240
hawnhekk hija xi data importanti.

1101
00:50:51,240 --> 00:50:52,800
Hawnhekk huwa xi data iktar importanti.

1102
00:50:52,800 --> 00:50:56,500
Barra minn hekk, hawnhekk huwa l-
"L-ewwel" ta 'data importanti tiegħi.

1103
00:50:56,500 --> 00:51:01,050
Allura HTML hija dwar tip
ta teggjar, litteralment, kliem

1104
00:51:01,050 --> 00:51:05,270
u l-paragrafi u kostrutti fil tiegħek
paġna ma dawn l-ideat ftit, jekk inti

1105
00:51:05,270 --> 00:51:07,640
se, li inti tista '
b'xi lieva li jużaw

1106
00:51:07,640 --> 00:51:10,880
tekniki oħra bħal CSS b'dan il-mod.

1107
00:51:10,880 --> 00:51:14,760
>> Allura b'risposta għad-domanda Victoria,
nistgħu nagħmlu test akbar b'dan il-mod.

1108
00:51:14,760 --> 00:51:18,380
Hemm modi tant oħrajn, iżda
il-font tag-- parentesi miftuħa "font" -

1109
00:51:18,380 --> 00:51:19,770
huwa attwalment bosta snin qodma.

1110
00:51:19,770 --> 00:51:21,410
U dan huwa l-problema,
wisq, ma bbażat ruħha biss

1111
00:51:21,410 --> 00:51:23,485
dwar resources-- internet
dawn għandhom tendenza li jkunu skaduti.

minħabba li l-dinja realizzati,

1113
00:51:26,110 --> 00:51:28,970
dak ma "font-size = 7" jfisser?

1114
00:51:28,970 --> 00:51:29,670
Hija ma.

1115
00:51:29,670 --> 00:51:32,770
U hekk għal ħafna snin u sa
din il day-- wieħed mill-ġenb

1116
00:51:32,770 --> 00:51:36,060
jinnota hawnhekk hija li huwa attwalment
oerhört uġigħ xorta kultant

1117
00:51:36,060 --> 00:51:38,900

u Google u Mozilla u
oħrajn ta 'spiss ma jaqblux dwar kif

1119
00:51:44,220 --> 00:51:47,480
sabiex tinterpreta speċifikazzjoni bħal HTML.

1120
00:51:47,480 --> 00:51:52,490
>> Hemm ktieb tar-regoli għas HTML li
ġeneralment jgħid dak li kull tikketta mezzi.

1121

00:54:16,430 --> 00:54:20,630
U hekk f'xi punt, il
maniġers prodott jew l-inġiniera

1170
00:54:20,630 --> 00:54:23,620
bżonn tagħmel decision-- inti
taf liema, biss 1% tad-dinja

1171
00:54:23,620 --> 00:54:24,740
għadha tuża IE 7.

1172
00:54:24,740 --> 00:54:25,490
Biex infern magħhom.

1173
00:54:25,490 --> 00:54:27,470
Aħna biss mhux se
isostni din browser.

1174
00:54:27,470 --> 00:54:28,740
U dak ma jfisser li ma jappoġġawx?

1175
00:54:28,740 --> 00:54:31,170
Jista 'jfisser li buttuni
ma jaħdmux fuq il-paġna web tiegħek,

1176
00:54:31,170 --> 00:54:33,050
jew jista 'jfisser il-
ifformattjar hija kompletament off.

1177
00:54:33,050 --> 00:54:35,091
Jew inti jista 'jkollu jagħmel
dik l-istess sentenza sejħa

1178
00:54:35,091 --> 00:54:39,089
fil mobbli f'dawn il-jiem, fejn, aħna qed
mhux ser jappoġġja IOS 5 aktar.

1179
00:54:39,089 --> 00:54:40,380
Sabiex in-nies biss għandhom jaġġornaw.

1180
00:54:40,380 --> 00:54:45,850
Jew aħna mhux qed tmur biex tappoġġja cupcake
fuq Android OS għall-mezzi Android,

1181
00:54:45,850 --> 00:54:48,629
għaliex kif l world-- bħala l-
dinja ta 'teknoloġija trid timxi' l quddiem,

1182
00:54:48,629 --> 00:54:51,170
dan it-tip ta trid jkaxkru l-
dinja magħha b'tali mod li dawn ma jkunux

1183
00:54:51,170 --> 00:54:53,295
għandhom ikomplu jkunu
kompatibbli lura sabiex ikunu

1184
00:54:53,295 --> 00:54:54,920
jistgħu joffru karatteristiċi ġodda u tajbin.

1185
00:54:54,920 --> 00:54:57,878
Dan huwa tabilħaqq waħda mir-raġunijiet
għaliex kumpaniji tant huma rolling out

1186
00:54:57,878 --> 00:55:01,440
aġġornamenti awtomatiċi u tip ta 'sfurzar
l-aħħar verżjonijiet ta 'softwer fuqna.

1187
00:55:01,440 --> 00:55:04,010
U anke kumpaniji
bħal Apple se sort ta

1188
00:55:04,010 --> 00:55:07,280
seħħ inti kważi jew iġġiegħel
ai termini ta 'forzi tas-suq

1189
00:55:07,280 --> 00:55:11,164
biex jixtru telefon ġdid minħabba li huma biss
mhux se taġġorna telefon qadim tiegħek jibqgħalu.

1190
00:55:11,164 --> 00:55:13,330
Allura tinsa fuq il
aħħar u l-karatteristiċi akbar,

1191
00:55:13,330 --> 00:55:17,520
għaliex dan huwa għali lilhom bħala
kumpanija li żżomm anzjani, forsi

1192
00:55:17,520 --> 00:55:19,330
Verżjonijiet inferjuri ta 'softwer.

1193
00:55:19,330 --> 00:55:23,660
Imma l-effett nett huwa li
aħna wkoll ibatu dan ukoll.

1194
00:55:23,660 --> 00:55:26,550
>> Mela ejja tagħti ħarsa lejn ftit
ftit affarijiet finali hawn.

1195
00:55:26,550 --> 00:55:29,740
Ejja knock off malajr reali wħud mill
dawk balal oħra, jekk kurjuż.

1196
00:55:29,740 --> 00:55:33,440
Mela jekk inti kienu qegħdin jippruvaw,
per eżempju, il-pożizzjoni

1197
00:55:33,440 --> 00:55:36,420
it-test fuq naħat differenti tal-
paġna, jien ser tagħmel mod wieħed malajr,

1198
00:55:36,420 --> 00:55:38,360
imma hemm differenti
modi kif dan isir.

1199
00:55:38,360 --> 00:55:42,610
Let me imorru quddiem u eliminate--
jissimplifika dan li ġej.

1200
00:55:42,610 --> 00:55:45,330
Let me biss jmorru lura għall tiegħi
sempliċi, il-paragrafi sempliċi.

1201
00:55:45,330 --> 00:55:47,760
Let me jmorru lura għall styles.css tiegħi.

1202
00:55:47,760 --> 00:55:51,040
U jien biss ser tuża l-simple--
li inti tista raw fuq Google

1203
00:55:51,040 --> 00:55:54,430
jew li jittieħed lura mill earlier--
-Test jaqbel dritt.

1204
00:55:54,430 --> 00:55:56,220
U rikarigu din il-paġna.

1205
00:55:56,220 --> 00:55:58,470
Issa kollox jidher
li jkun tajjeb allinjati,

1206
00:55:58,470 --> 00:56:00,770
kif inti tista 'tara fuq l-overhead hawn.

1207
00:56:00,770 --> 00:56:04,470
>> Nistgħu jagħmluha ħarsa ftit aktar
ktieb simili, u nistgħu ngħidu "jiġġustifikaw"

1208
00:56:04,470 --> 00:56:05,640
u rikarigu.

1209
00:56:05,640 --> 00:56:09,870
Issa huwa sabiħ u kwadri kemm fuq
ġnub, li huwa tip ta 'sbieħ.

1210
00:56:09,870 --> 00:56:12,220
Ieħor għan li kellna hawn
Kien bidla fil-kulur tat-test.

1211
00:56:12,220 --> 00:56:13,650
Allura rajna li b'test aħmar tiegħi.

1212
00:56:13,650 --> 00:56:15,630
U issa żid buttuni għal forma.

1213
00:56:15,630 --> 00:56:19,390
Allura għaliex ma nippruvaw nagħmlu eżattament dan?

1214
00:56:19,390 --> 00:56:23,656
Iżda l-ewwel let me go għal sit li
ħafna minna jużaw kull day-- Google.

1215
00:56:23,656 --> 00:56:25,780
U ejja tagħti ħarsa lejn
kif Google attwalment xogħlijiet.

1216
00:56:25,780 --> 00:56:26,821
Imma jien ser tagħmel dan.

1217
00:56:26,821 --> 00:56:31,930
L-ewwel let me tagħmel dan in-- Yep,
let me go Google ewwel.

1218
00:56:31,930 --> 00:56:34,530
Jien ser ikollhom imorru
fil Google Settings,

1219
00:56:34,530 --> 00:56:40,660
għaliex nixtieq li jiskonnettja
xi ħaġa imsejħa Riżultati Instant.

1220
00:56:40,660 --> 00:56:43,580
>> Allura inti jista 'jkollok ndunat fil
Google dawn days-- let me jmorru lura

1221
00:56:43,580 --> 00:56:44,850
u mbagħad din fuq.

1222
00:56:44,850 --> 00:56:47,900
Mela jekk jien tibda tiftix
għal "qtates" bħal dan,

1223
00:56:47,900 --> 00:56:50,120
avviż li mhux biss tagħmel
I nikseb auto-jitlesta up

1224
00:56:50,120 --> 00:56:54,520
quċċata, kollha f'daqqa, il-paġna innifsu
jidher li bidla pretty malajr kif ukoll,

1225
00:56:54,520 --> 00:56:58,750
u li l-Google tuża lingwa
imsejħa JavaScript jippruvaw li jkun utli.

1226
00:56:58,750 --> 00:57:01,540
Iżda sfortunatament, huwa tip
tal messijiet up diskussjoni tagħna

1227
00:57:01,540 --> 00:57:04,010
ta dak li verament jiġri
taħt il-barnuża hawn.

1228
00:57:04,010 --> 00:57:09,070
So I am biss tip ta 'malajr
itfi riżultati istantanji.

1229
00:57:09,070 --> 00:57:11,510
U jien ser ikklikkja Save.

1230
00:57:11,510 --> 00:57:13,930
U issa jien ser tiftaħ
li toolbar dijanjostiċi li I

1231
00:57:13,930 --> 00:57:16,150
iżommu ftuħ taħt il-tab Netwerk.

1232
00:57:16,150 --> 00:57:17,720
Mela ejja tagħmel dan.

1233
00:57:17,720 --> 00:57:21,960
Ħalli me-- whoops--
iscroll din stabbiliti daqsxejn.

1234
00:57:21,960 --> 00:57:24,410
U let me tfittxija għal "qtates."

1235
00:57:24,410 --> 00:57:26,790
>> U issa notice-- attwalment,
din hija opportunità tajba

1236
00:57:26,790 --> 00:57:28,840
biex jiddiskutu għal mument.

1237
00:57:28,840 --> 00:57:32,460
Avviż l-mument I type-- jitwaqqaf.

1238
00:57:32,460 --> 00:57:35,250
Ieqaf.

1239
00:57:35,250 --> 00:57:35,790
KOLLOX SEW.

1240
00:57:35,790 --> 00:57:40,870
Avviż l-mument I ittajpja l-ittra
Ċ, tara l-qiegħ tal-iskrin.

1241
00:57:40,870 --> 00:57:48,600
A- T- S. X'tagħmel il-qiegħ
ta 'dan l-iskrin, tab Netwerk tiegħi,

1242
00:57:48,600 --> 00:57:53,320
jissuġġerixxu li qed jiġri kull
darba I tip ittra?

1243
00:57:53,320 --> 00:57:57,700
Sfortunatament, il-Żrinġ huwa ferm
jfixkluh illum jew il Shamrock

1244
00:57:57,700 --> 00:58:00,339
jew kwalunkwe huwa.

1245
00:58:00,339 --> 00:58:01,880
Dak li kien qed jiġri kull darba I ittajpjat?

1246
00:58:01,880 --> 00:58:04,230
U let me ċar l-
buffer u tip ġdid.

1247
00:58:04,230 --> 00:58:06,580
Whoops So--.

1248
00:58:06,580 --> 00:58:13,280
Kull darba I tip ittra, C- A- T--
hekk ringiela ġdida ovvjament jżomm jidhru.

1249
00:58:13,280 --> 00:58:16,530
Xi jfisser kull waħda minn dawn il ringieli jirrappreżentaw,
ibbażati fuq dak li aħna stajt tidher u diskussi

1250
00:58:16,530 --> 00:58:17,339
s'issa?

1251
00:58:17,339 --> 00:58:18,130
UDJENZA: A tfittxija?

1252
00:58:18,130 --> 00:58:21,770
DAVID J. Malan: A tfittxija, jew
aktar ġeneriku, talba HTTP

1253
00:58:21,770 --> 00:58:23,125
mill-browser tiegħi għal server.

1254
00:58:23,125 --> 00:58:29,090
Ukoll, għaliex qed browser tiegħi tagħmel HTTP
jitlob kull darba I tip ittra?

1255
00:58:29,090 --> 00:58:30,502
>> UDJENZA: [inaudible]

1256
00:58:30,502 --> 00:58:33,210
DAVID J. Malan: Yeah, huwa jagħti
me dawn auto-komplet riżultati.

1257
00:58:33,210 --> 00:58:35,190
Bħal, meta jagħmlu dawn
rizultati jiġu minn?

1258
00:58:35,190 --> 00:58:38,120
Ukoll, kull darba I tip ta '
ittra, Google jibgħat aktar

1259
00:58:38,120 --> 00:58:40,460
u aktar u aktar ta '
-kelma jien ittajpjar.

1260
00:58:40,460 --> 00:58:41,040
Għaliex?

1261
00:58:41,040 --> 00:58:44,540
Minħabba li jkunu jridu jagħtu me
aħjar u aħjar, suġġeriment aħjar,

1262
00:58:44,540 --> 00:58:48,880
lista ta 'suġġerimenti, għal liema kelma
Jien jippruvaw kważi lesti għal kollox.

1263
00:58:48,880 --> 00:58:53,030
Allura dan huwa li jgħidu litteralment kull
karattru inti tip fis-Google

1264
00:58:53,030 --> 00:58:56,900
qed tintbagħat, finalment fil
ingrossa, iżda wkoll kultant wieħed

1265
00:58:56,900 --> 00:59:00,620
fi żmien sabiex jiġu implimentati
dawn il-karatteristiċi auto-komplet meta

1266
00:59:00,620 --> 00:59:03,000
-data hija, ovvjament, fuq il-web.

1267
00:59:03,000 --> 00:59:08,780
>> Issa, ejja tagħti ħarsa lejn dak li attwalment
jiġri meta I ikklikkja Google Search.

1268
00:59:08,780 --> 00:59:10,420
U allura aħna ser lieva dan il nfusna.

1269
00:59:10,420 --> 00:59:15,320
Mela jekk jien iscroll issa l-ħafna
ewwel talba li ġara biss.

1270
00:59:15,320 --> 00:59:17,130
Avviż li ġej.

1271
00:59:17,130 --> 00:59:25,550
Dan ġie trażmess lil pjuttost twil URL--
https://www.google.com/search?

1272
00:59:25,550 --> 00:59:27,100
u mbagħad mazz sħiħ ta 'għalf.

1273
00:59:27,100 --> 00:59:29,620
Ejja naraw dan fil-fatt issa
fil-tab browser innifsu.

1274
00:59:29,620 --> 00:59:31,310
Ejja jeħles mill-toolbar hawn.

1275
00:59:31,310 --> 00:59:33,140
Hawn il-paġna ta 'rizultati.

1276
00:59:33,140 --> 00:59:34,790
U avviż hawnhekk l-URL.

1277
00:59:34,790 --> 00:59:37,430
Issa, inti tista 'probabbilment raden
x'inhu għaddej hawn parzjalment.

1278
00:59:37,430 --> 00:59:39,090
Allura l-ewwel nett, id-definizzjoni.

1279
00:59:39,090 --> 00:59:42,570
Din il apparentement hija d-destinazzjoni
fejn tiġi ppreżentata l-formola.

1280
00:59:42,570 --> 00:59:44,910
Allura meta I ittajpjat fil-
kliem "qtates" u hit Ikteb,

1281
00:59:44,910 --> 00:59:48,460
apparentement Google mibgħuta
test input tiegħi għal dan il-URL

1282
00:59:48,460 --> 00:59:50,770
li stajt enfasizzat
hemm, mmejla tfittxija.

1283
00:59:50,770 --> 00:59:56,530
Jirriżulta, fi URL, xi ħaġa li
jiġri wara marka kwistjoni hija,

1284
00:59:56,530 --> 01:00:01,270
kif inżommu qal, ta 'valur essenzjali par
li kien ittajpjat fil-forma jew b'xi mod

1285
01:00:01,270 --> 01:00:04,500
trasmessa mill-
-browser għall-server.

1286
01:00:04,500 --> 01:00:07,180
>> Allura kwalunkwe ħin li inti tip input
fil-forma fuq il-web

1287
01:00:07,180 --> 01:00:10,000
u huwa mibgħut kif konna
ilha tiddiskuti, permezz get,

1288
01:00:10,000 --> 01:00:12,400
wieħed minn dawn virtwali
envelops, il-kontenut

1289
01:00:12,400 --> 01:00:15,510
ta 'dak envelope-- iva, iżommu
jkollna mimli fiżikament

1290
01:00:15,510 --> 01:00:19,010
fil-pakkett fil-klassi
illum, iżda teknoloġikament

1291
01:00:19,010 --> 01:00:21,110
huwa fil-fatt imqiegħda fil-URL.

1292
01:00:21,110 --> 01:00:22,940
Allura fil-fatt, let me ffiltrati permezz ta 'dan.

1293
01:00:22,940 --> 01:00:25,010
Fejn tara jintuza mill-utent?

1294
01:00:25,010 --> 01:00:27,490
Meta inti tara xi ħaġa
li I myself ittajpjat up hawn?

1295
01:00:27,490 --> 01:00:32,100

1296
01:00:32,100 --> 01:00:33,491
Yeah, hekk "qtates."

1297
01:00:33,491 --> 01:00:33,990
Dritt?

1298
01:00:33,990 --> 01:00:36,380
So let me jiddistillaw din il
fis xi ħaġa sempliċi.

1299
01:00:36,380 --> 01:00:39,917
Jien ser titħassar kollox dwar
dan il-URL li jien ma jifhmux,

1300
01:00:39,917 --> 01:00:42,250
u jien biss ser jitilqu
bħala this-- / tfittxija? Q = qtates.

1301
01:00:42,250 --> 01:00:45,640

1302
01:00:45,640 --> 01:00:47,890
Ser naraw fejn q
ġej minn fil-mument,

1303
01:00:47,890 --> 01:00:51,220
iżda li jħoss bħall-minimu
ammont ta 'informazzjoni li I pprovduta.

1304
01:00:51,220 --> 01:00:53,050
U issa jien ser hit Ikteb.

1305
01:00:53,050 --> 01:00:55,520
U avviż għadu jaħdem.

1306
01:00:55,520 --> 01:00:57,950
Aħna xorta jiksbu lura mazz sħiħ ta 'qtates.

1307
01:00:57,950 --> 01:01:00,340
Allura Google hija fancier
minn dan il f'dawn il-jiem.

1308
01:01:00,340 --> 01:01:01,934
Huwa 2016, mhux 1999.

1309
01:01:01,934 --> 01:01:04,600
Allura hemm Jittieħed oħra li tiegħi
browser hija li jibgħat lis-server.

1310
01:01:04,600 --> 01:01:07,100
Iżda din hija minimament
kollu li l-meħtieġa.

1311
01:01:07,100 --> 01:01:08,380
>> Allura x'inhu għaddej?

1312
01:01:08,380 --> 01:01:14,320
Ukoll, l-ewwel let me imorru quddiem u jmorru
lura għall-Cloud9 u let me jimxi 'l quddiem

1313
01:01:14,320 --> 01:01:15,620
u agħlaq tabs tiegħi qabel.

1314
01:01:15,620 --> 01:01:18,230
U jien ser tagħmel dan fuq tiegħi
stess biss għal mument.

1315
01:01:18,230 --> 01:01:20,730
Jien ser jimxi 'l quddiem
u joħolqu fajl ġdid.

1316
01:01:20,730 --> 01:01:23,739
U jien ser ħlief bħala google.html.

1317
01:01:23,739 --> 01:01:26,280
U jien ser quickly-- ħafna
Jien ser steal, fil-fatt,

1318
01:01:26,280 --> 01:01:28,510
xi wħud minn dan it-test biss biex jiffrankaw il-ħin.

1319
01:01:28,510 --> 01:01:30,610
Jien ser paste dan fil hawn.

1320
01:01:30,610 --> 01:01:33,850
Jien ma jmur biex jolqot bl
kwalunkwe stylization dan iż-żmien.

1321
01:01:33,850 --> 01:01:38,340
Aħna qed tmur biex sejħa dan "Google tiegħi."

1322
01:01:38,340 --> 01:01:41,230
U jien ser teħles
ta 'kollox fil-ġisem.

1323
01:01:41,230 --> 01:01:42,740
U jien ser jagħmlu dan li ġej.

1324
01:01:42,740 --> 01:01:45,690
Let me zoom in.

1325
01:01:45,690 --> 01:01:50,620
Formola action-- u kif semmejt fil-qosor
earlier-- whoops-- kif I qosor

1326
01:01:50,620 --> 01:01:54,130
imsemmi qabel, l-azzjoni ta '
formola huwa fejn inti tibgħat l-informazzjoni li.

1327
01:01:54,130 --> 01:01:56,620
Allura google.com/search.

1328
01:01:56,620 --> 01:01:59,390
U l-metodu nixtieq li jużaw
jista 'jkun wieħed minn żewġ affarijiet.

1329
01:01:59,390 --> 01:02:02,870
Dan jista 'jkun jew "jiksbu," kif inżommu
tiddiskuti, jew tista 'tkun "posta."

1330
01:02:02,870 --> 01:02:05,340
Għal issa, il-fundamentali
differenza hija, jekk inti tuża "jiksbu,"

1331
01:02:05,340 --> 01:02:09,590
l-informazzjoni kollha li l-
utent jipprovdi gets mibgħuta fil-URL.

1332
01:02:09,590 --> 01:02:13,530
>> Dan huwa kbir għal affarijiet simili tfittxija
magni u xi applikazzjonijiet oħra ftit,

1333
01:02:13,530 --> 01:02:17,080
imma f'liema ċirkustanzi kieku
inti ma tridx li jimla formola

1334
01:02:17,080 --> 01:02:21,620
u l-informazzjoni jispiċċaw il-
URL, bħal fil address bar tal-browser tiegħek?

1335
01:02:21,620 --> 01:02:25,470

1336
01:02:25,470 --> 01:02:26,605
X'tip ta 'forom do you--

1337
01:02:26,605 --> 01:02:27,480
UDJENZA: [inaudible]

1338
01:02:27,480 --> 01:02:28,450
DAVID J. Malan: Yeah, bħal dak?

1339
01:02:28,450 --> 01:02:29,270
UDJENZA: passwords.

1340
01:02:29,270 --> 01:02:31,936
DAVID J. Malan: Yeah, sabiex inti log
fl għal Facebook jew xi websajt.

1341
01:02:31,936 --> 01:02:34,395
C'est jintuza mill-utent mill
forma, kaxxa ta 'test,

1342
01:02:34,395 --> 01:02:37,020
imma inti probabilment ma jridux dan
juru fil URL tal-browser.

1343
01:02:37,020 --> 01:02:38,121
Għaliex?

1344
01:02:38,121 --> 01:02:40,870
I mean, forsi hemm xi
implikazzjonijiet ta 'sigurtà fuq in-netwerk,

1345
01:02:40,870 --> 01:02:44,830
iżda more-- simili, aktar sempliċi, dak li jekk
roommate tiegħek, tiegħek sinifikanti oħra,

1346
01:02:44,830 --> 01:02:47,710
gidjien tiegħek, mara tiegħek jistenna
matul l-istorja browser tiegħek?

1347
01:02:47,710 --> 01:02:50,762
Hemm huwa dritt password tiegħek
hemm fl-istorja browser tiegħek.

1348
01:02:50,762 --> 01:02:52,220
Dan ma jħossu bħal disinn tajjeb.

1349
01:02:52,220 --> 01:02:54,500
Jew saħansitra aktar teknikament,
ejja ngħidu li inti qed tipprova

1350
01:02:54,500 --> 01:02:59,180
li upload ritratt biex Flickr
jew Facebook jew wherever--

1351
01:02:59,180 --> 01:03:03,010
jiġifieri jintuza mill-utent, anki jekk
huwa ftit aktar interesting-- kif

1352
01:03:03,010 --> 01:03:05,530
nista CRAM immaġini fil-bar URL?

1353
01:03:05,530 --> 01:03:06,730
Inti tip ta 'tip ta' ma jistgħux.

1354
01:03:06,730 --> 01:03:07,396
Inti tip ta 'tista'.

1355
01:03:07,396 --> 01:03:10,210
Iżda, verament, jien hard-pressed
li wieħed jimmaġina tagħmel dan.

1356
01:03:10,210 --> 01:03:13,470
So I bżonn metodu ieħor għal
uploading ritratti għall-websajt,

1357
01:03:13,470 --> 01:03:15,657
u dak il-metodu ieħor huwa msejjaħ "posta."

1358
01:03:15,657 --> 01:03:18,740
Iżda għal issa, aħna ser biss jitkellmu dwar
"Jiksbu", li huwa l-aktar sempliċi tat-tnejn.

1359
01:03:18,740 --> 01:03:21,100
Hija biss jpoġġi l-
jintuza mill-utent fil-URL.

1360
01:03:21,100 --> 01:03:22,830
>> Allura hawnhekk-formola jien ħolqien.

1361
01:03:22,830 --> 01:03:24,070
Irrid input.

1362
01:03:24,070 --> 01:03:24,820
U inti taf liema?

1363
01:03:24,820 --> 01:03:26,111
Jien ser tieħu raden hawn.

1364
01:03:26,111 --> 01:03:31,600
Jien ser jiftakar tiegħi
input "Q" għal "query."

1365
01:03:31,600 --> 01:03:34,970
U jien naħseb li din hija waħda mill-
disinji oriġinali, forsi, mill-1999.

1366
01:03:34,970 --> 01:03:39,560
U allura l-tip ta 'dan il-kontribut
huwa biss se tkun "test."

1367
01:03:39,560 --> 01:03:43,040
U mbagħad jien ser ikollhom kontribut ieħor
li ma jkunx jeħtieġ isem, kif aħna ser dalwaqt

1368
01:03:43,040 --> 01:03:45,120
ara,-tip tagħha huwa "tressaq."

1369
01:03:45,120 --> 01:03:47,070
U dan se
tagħti me buttuna speċjali.

1370
01:03:47,070 --> 01:03:48,320
U li hu.

1371
01:03:48,320 --> 01:03:50,790
>> So let me go quddiem u jiffrankaw dan il-fajl.

1372
01:03:50,790 --> 01:03:54,910
Jien se jmorru lura għall tiegħi
browser u mur google.html.

1373
01:03:54,910 --> 01:03:56,140
Ikteb.

1374
01:03:56,140 --> 01:03:59,680
U huwa tip ta skarsa
jiġifieri l-inqas.

1375
01:03:59,680 --> 01:04:03,110
Imma ħalluni jimxi 'l quddiem
u tfittxija għal "qtates."

1376
01:04:03,110 --> 01:04:06,510
U Avviż jien bħalissa
fuq dan il-URL Cloud9.

1377
01:04:06,510 --> 01:04:09,240
Iżda l-mument I ikklikkja dan,
fejn do inti t-tama I ser jispiċċaw?

1378
01:04:09,240 --> 01:04:10,160
>> UDJENZA: Google.

1379
01:04:10,160 --> 01:04:11,118
>> DAVID J. Malan: Google.

1380
01:04:11,118 --> 01:04:12,740
Mela ejja ikklikkja Submit.

1381
01:04:12,740 --> 01:04:15,200
U fil-fatt stajt jerġgħu implimentati Google.

1382
01:04:15,200 --> 01:04:15,700
Dritt?

1383
01:04:15,700 --> 01:04:16,480
Huwa sempliċi.

1384
01:04:16,480 --> 01:04:17,120
Huwa eħfef.

1385
01:04:17,120 --> 01:04:20,350
I mean, kodiċi tiegħi huwa manifestament aħjar minn
tagħhom, mill-mess rajna qabel.

1386
01:04:20,350 --> 01:04:21,100
U inti taf liema?

1387
01:04:21,100 --> 01:04:22,610
Jien ser ħwawar dan up ftit.

1388
01:04:22,610 --> 01:04:23,860
I ma jsemmi dan qabel.

1389
01:04:23,860 --> 01:04:27,860
Hemm tags bħal H1, għall-Intestatura 1,
l-intestatura l-aktar importanti fil-paġna.

1390
01:04:27,860 --> 01:04:30,570
"Google tiegħi," jien ser sejħa din.

1391
01:04:30,570 --> 01:04:31,940
Let me rikarigu.

1392
01:04:31,940 --> 01:04:33,772
Huwa tfittex ftit aħjar diġà.

1393
01:04:33,772 --> 01:04:34,980
U, fil-fatt, inti taf liema?

1394
01:04:34,980 --> 01:04:36,430
Stajt already-- I gideb.

1395
01:04:36,430 --> 01:04:40,200
I said I ma kienx se stil dan,
imma jien ser stil din il bħal qabel.

1396
01:04:40,200 --> 01:04:46,860
U l-korp tiegħi se tkun,
ejja ngħidu, ċentru test jallinjaw.

1397
01:04:46,860 --> 01:04:48,800
Huwa tfittex aktar bħall-Google diġà.

1398
01:04:48,800 --> 01:04:51,090
>> I bżonn ta 'waqfa linja, għalkemm,
għal dak Issottometti buttuna.

1399
01:04:51,090 --> 01:04:52,798
U jirriżulta, inti
jistgħu jużaw il-paragrafi,

1400
01:04:52,798 --> 01:04:57,320
jew inti tista 'aktar litteralment biss jgħidu,
tagħti me a line waqfa here---tikketta br.

1401
01:04:57,320 --> 01:04:59,319
U jekk jien jerġgħu jitgħabbew dan, issa din tmur hemmhekk.

1402
01:04:59,319 --> 01:05:01,610
Huwa ftit ikrah, so I
tista 'tagħmel waqfiet linja multipli,

1403
01:05:01,610 --> 01:05:03,310
imma ejja ma jsibux wisq greedy hawn.

1404
01:05:03,310 --> 01:05:06,430
Allura issa ejja ara jekk din taħdem għal "klieb."

1405
01:05:06,430 --> 01:05:08,640
Jidher li jaħdem għal "klieb," kif ukoll.

1406
01:05:08,640 --> 01:05:10,780
Allura x'inhu l-takeaway konvinċenti hawn?

1407
01:05:10,780 --> 01:05:13,600
One-- ma kienx qabża kbira għall-
tintroduċi ftit tags aktar,

1408
01:05:13,600 --> 01:05:15,370
bħall-formola tikketta fil-tikketta input.

1409
01:05:15,370 --> 01:05:17,120
Iżda aktar fundamentali
huwa, kollox aħna qed tagħmel

1410
01:05:17,120 --> 01:05:20,610
huwa lieva għarfien tagħna
tal HTTP u l-fatt

1411
01:05:20,610 --> 01:05:24,900
li l-forom finalment tbiddel
x'hemm fil-URL tal-browser,

1412
01:05:24,900 --> 01:05:28,540
u għalhekk, għalhekk, nistgħu
mekkanikament tipprovdi kontribut għal server

1413
01:05:28,540 --> 01:05:33,600
billi jagħmel formola HTML u jafu
li s-server jifhem HTTP,

1414
01:05:33,600 --> 01:05:36,890
bħad-ġisem tagħna jifhem, bħal,
tħawwad idejn tiegħi, dik l-istess protokoll,

1415
01:05:36,890 --> 01:05:40,920
u għalhekk irridu jiksbu lura l-rispons
li aħna finalment nistennew.

1416
01:05:40,920 --> 01:05:44,050
>> Mela ejja jipprova jagħmel wieħed
aħħar ħaġa issa ma mobbli,

1417
01:05:44,050 --> 01:05:47,052
u jien ser make-- I ser żid
dan il-kodiċi għall-pjastri.

1418
01:05:47,052 --> 01:05:49,760
Mela jekk inti tixtieq li tinker, inti
jista 'ċertament teħodha minn hemm.

1419
01:05:49,760 --> 01:05:51,551
Imma jien se jmorru
quddiem u jagħmlu ħaġa waħda.

1420
01:05:51,551 --> 01:05:54,120
Jien ser jimxi 'l quddiem u
jiftħu page-- indiċi tiegħi

1421
01:05:54,120 --> 01:05:59,030
paġna bonjour tiegħi bħal qabel, li
għandha ħafna ta 'dan it-test faux-Latin,

1422
01:05:59,030 --> 01:06:05,470
jew bla sens test Latina, u has--
jidher qisu dan fil dan id-daqs tat-tipa.

1423
01:06:05,470 --> 01:06:07,850
Imma ħalluni jimxi 'l quddiem u jagħmlu dan.

1424
01:06:07,850 --> 01:06:09,300
Jien se jmorru fil Cloud9.

1425
01:06:09,300 --> 01:06:10,380
U inti ma għandekx tagħmel dan il-pass.

1426
01:06:10,380 --> 01:06:11,420
I ser biss tagħmel dan myself.

1427
01:06:11,420 --> 01:06:12,890
Jien ser ikklikkja Share.

1428
01:06:12,890 --> 01:06:15,170
U dan huwa fattur
biss ta 'Cloud9, fejn

1429
01:06:15,170 --> 01:06:17,710
I jistgħu jagħmlu ambjent tiegħi pubbliku.

1430
01:06:17,710 --> 01:06:20,240
>> U biss għall-fini ta '
dimostrazzjoni, let me jagħmlu dan.

1431
01:06:20,240 --> 01:06:22,870
Jien ser tagħmel applikazzjoni pubbliku tiegħi.

1432
01:06:22,870 --> 01:06:25,230
Avviż huwa twissija me, am
Jien ċert I tixtieq li tagħmel dan,

1433
01:06:25,230 --> 01:06:28,438
għax dan se jagħmlu kulħadd
fid-dinja, kemm jekk dawn qed hawn issa

1434
01:06:28,438 --> 01:06:33,560
jew jaraw il-video aktar tard fl-
-internet tista 'tara dak li nara.

1435
01:06:33,560 --> 01:06:34,440
Imma dak li OK.

1436
01:06:34,440 --> 01:06:37,870
Jien se ngħid "Magħmul".

1437
01:06:37,870 --> 01:06:42,080
U let me ninkoraġġukom, jekk I ma
dan il correctly-- let me tittestja l-ewwel.

1438
01:06:42,080 --> 01:06:45,590
Jimxi 'l quddiem, jekk inti ma mind--
fil-browser fuq il-kompjuter tiegħek,

1439
01:06:45,590 --> 01:06:49,900
mur dan il-URL, u nisperaw
tkun taf tara test Latin tiegħi.

1440
01:06:49,900 --> 01:06:52,820
U li tkun ċara, huwa
running mhux fuq laptop tiegħi.

1441
01:06:52,820 --> 01:06:53,610
Huwa fil-sħaba.

1442
01:06:53,610 --> 01:06:58,120
Huwa fuq Cloud9, litteralment, iżda
Stajt magħmula pubbliċi workspace tiegħi

1443
01:06:58,120 --> 01:07:03,450
hekk li kulħadd fuq l-internet
tista 'aċċess home page Latina tiegħi.

KOLLOX SEW.

1457
01:07:51,540 --> 01:07:53,530
Allura nista 'żżomm sa tiegħek
telefon għal ftit mument?

1458
01:07:53,530 --> 01:07:57,504
Allura, wieħed jittama, jekk int aċċess
dan, għandu tfittex kważi tinqarax.

1459
01:07:57,504 --> 01:07:59,920
Huwa still-- I mean, huwa
jinqarax minħabba l-Latin.

1460
01:07:59,920 --> 01:08:01,920
Imma hija wkoll tinqarax
għal liema raġuni oħra?

1461
01:08:01,920 --> 01:08:03,775
Bħal, liema displeases inti dwar dan?

1462
01:08:03,775 --> 01:08:04,650
UDJENZA: Huwa żgħar.

1463
01:08:04,650 --> 01:08:06,420
DAVID J. Malan: Huwa super, super żgħar.

1464
01:08:06,420 --> 01:08:07,920
Allura kif nistgħu jiffissaw dan?

1465
01:08:07,920 --> 01:08:09,730
Huwa super, super żgħar
fuq il-mobile Victoria

1466
01:08:09,730 --> 01:08:11,400
u, jekk inti ħadthom jinġibed
it up lilek innifsek, probabbilment

1467
01:08:11,400 --> 01:08:14,660
żgħar fuq il-mobile tiegħek kif ukoll, sakemm inti
settings aċċessibilità ppermettiet.

1468
01:08:14,660 --> 01:08:15,530
Dak X'inhu?

1469
01:08:15,530 --> 01:08:18,497
Inti tista 'sempliċiment niskata u
zoom, li huwa fattibbli,

1470
01:08:18,497 --> 01:08:20,330
iżda imbagħad inti biss tara
ftit kliem fi żmien.

1471
01:08:20,330 --> 01:08:20,859
Allura stenna minuta.

1472
01:08:20,859 --> 01:08:21,720
Naf kif jiffissaw dan il.

1473
01:08:21,720 --> 01:08:22,219
Dritt?

1474
01:08:22,219 --> 01:08:26,130
I jistgħu jużaw CSS, u I jistgħu jibdlu l-
daqs tat-tipa minn 12-il punt għal 24-punt.

1475
01:08:26,130 --> 01:08:29,020
Imma l-effett sekondarju ta 'dan,
naturalment, se tkun issa,

1476
01:08:29,020 --> 01:08:32,630
fuq id-desktop jew laptop,
issa t-test huwa darbtejn akbar.

1477
01:08:32,630 --> 01:08:35,810
U hekk ikun tip ta 'sbieħ
li ssir distinzjoni bejn l-apparat,

1478
01:08:35,810 --> 01:08:37,840
u jirriżulta hemmhekk
huma modi ta 'kif isir dan.

1479
01:08:37,840 --> 01:08:39,590
Hemm diversi
modi differenti, fil-fatt,

1480
01:08:39,590 --> 01:08:44,189
li biha jużaw CSS u l-karatteristiċi fancier
li aħna mhux se tidħol fis f'dettall kbir,

1481
01:08:44,189 --> 01:08:46,960
inti tista 'essenzjalment query
il-browser u jgħidu,

1482
01:08:46,960 --> 01:08:51,550
jekk l-iskrin tiegħek hija iżgħar minn din il-
ħafna pixels, l-użu dan id-daqs tat-tipa.

1483
01:08:51,550 --> 01:08:55,180
Jekk iskrin tiegħek hija akbar minn dan il
ħafna pixels, l-użu dan id-daqs ieħor tat-tipa.

1484
01:08:55,180 --> 01:08:57,080
>> Tista 'tkun anki fancier għadu.

1485
01:08:57,080 --> 01:09:00,140
Jekk inti stajt qatt żar
paġna tal-web li, fuq desktop,

1486
01:09:00,140 --> 01:09:04,404
għandha menu kbir forsi off għall-
naħa, u allura kollha tal-kontenut

1487
01:09:04,404 --> 01:09:07,029
huwa li l-ġenb ta 'dik menu--
li tip ta 'paradigma komuni.

1488
01:09:07,029 --> 01:09:09,670
Menu fuq, il-kontenut tax-xellug
dwar id-dritt, jew viċi versa.

1489
01:09:09,670 --> 01:09:13,569
Ma verament ix-xogħol fuq il-mowbajl tiegħek meta
iskrin huwa biss dan ħafna pixels wiesgħa.

1490
01:09:13,569 --> 01:09:16,233
Allura aktar komuni fuq il-mowbajl huwa,
menu tiegħek se f'daqqa tikseb

1491
01:09:16,233 --> 01:09:18,399
waqa ', u inti għandek biex
ikklikkja l-buttuna biex tara dan,

1492
01:09:18,399 --> 01:09:22,404
jew il-websajt se tpoġġi l-menu
hawn fuq u tpoġġi l-kontenut taħtha.

1493
01:09:22,404 --> 01:09:24,779
U inti tista 'timplimenta dawn
affarijiet b'modi multipli, wisq.

1494
01:09:24,779 --> 01:09:28,340
Tista 'titlob programmaturi tiegħek,
ħej, tim, kwalunkwe ħin

1495
01:09:28,340 --> 01:09:34,450
tara xi talba HTTP minn Android
apparat, apparat Microsoft, Google

1496
01:09:34,450 --> 01:09:39,930
apparat, apparat Apple, jużaw dan
daqs tat-tipa u l-użu dan id-disinn menu,

1497
01:09:39,930 --> 01:09:42,670
jew inkella jużaw it-tqassim din il default akbar.

1498
01:09:42,670 --> 01:09:45,410
>> Issa, bl-użu dak
teknika fundamentali llum

1499
01:09:45,410 --> 01:09:48,529
jista 'l-inġiniera jużaw
tkun taf jekk huwa

1500
01:09:48,529 --> 01:09:53,660
iPhone, telefon Android, laptop,
desktop jżuru server tal-kumpanija?

1501
01:09:53,660 --> 01:09:55,310
Fejn do huma jiksbu din l-informazzjoni?

1502
01:09:55,310 --> 01:09:56,080
>> UDJENZA: Header?

1503
01:09:56,080 --> 01:09:57,740
>> DAVID J. Malan: Yeah, il-header HTTP.

1504
01:09:57,740 --> 01:10:01,714
Allura kull talba HTTP ġejjin minn
klijenti tagħhom għal servers tagħhom

1505
01:10:01,714 --> 01:10:03,880
jinkludu, ġewwa dak virtwali
envelop, mazz sħiħ

1506
01:10:03,880 --> 01:10:08,260
ta headers HTTP, li waħda minnhom hija
il-browser u s-sistema operattiva

1507
01:10:08,260 --> 01:10:10,290
anki, jekk inti kura biex
dak il-livell ta 'dettall.

1508
01:10:10,290 --> 01:10:13,790
Issa, huwa string cryptic tħares, iżda
teżisti software li se biss

1509
01:10:13,790 --> 01:10:18,530
jissimplifikaw li, u inti tista 'sempliċement titlob
fl-ipprogrammar code-- PHP, Java, C ++,

1510
01:10:18,530 --> 01:10:23,650
whatever-- dak telefown huwa this--
dak il-mezz huwa dan l-utent bl-użu?

1511
01:10:23,650 --> 01:10:27,501
U allura inti tista 'tgħid, juru lilhom dan il
Verżjoni tal-websajt jekk huwa ta 'telefon.

1512
01:10:27,501 --> 01:10:30,250
Urihom din il-verżjoni tal-
websajt jekk huwa laptop jew desktop.

1513
01:10:30,250 --> 01:10:32,316
Imma inti lanqas biss bżonn
kumplessità server-side.

1514
01:10:32,316 --> 01:10:33,940
Tista 'tagħmel anke l-aktar sempliċi ta' affarijiet.

1515
01:10:33,940 --> 01:10:34,815
>> Jien ser tagħmel dan.

1516
01:10:34,815 --> 01:10:38,995
Jien ser jimxi 'l quddiem fis
ambjent Cloud9 tiegħi,

1517
01:10:38,995 --> 01:10:41,370
u jien ser iżżid tag
li inti raw fil-Google qabel.

1518
01:10:41,370 --> 01:10:42,770
Huwa sejjaħ l-metatag.

1519
01:10:42,770 --> 01:10:45,520
U jien qatt ma ftakar dan wieħed, hekk
Jien ser tifformulaha mill-ġdid hawn.

1520
01:10:45,520 --> 01:10:50,552
isem meta = "viewport" u mbagħad
Kontenut = "wisa '= wisa mezz, intital

1521
01:10:50,552 --> 01:11:02,060
skala = 1 "u li hu.

1522
01:11:02,060 --> 01:11:06,230
>> Għalhekk jistgħu wkoll ikunu
bħal incantation maġika.

1523
01:11:06,230 --> 01:11:11,300
Huwa mhux kollha li ċari, iżda dan għandu
xi ħaġa li tagħmel ma 'l-viewport,

1524
01:11:11,300 --> 01:11:15,070
u l-viewport huwa biss l-korp ta '
paġna tal-web, ir-reġjun rettangolari li

1525
01:11:15,070 --> 01:11:16,690
jiddefinixxi l-aktar tal-paġna.

1526
01:11:16,690 --> 01:11:19,060
U dan huwa biss javżak
il-browser, inti taf liema?

1527
01:11:19,060 --> 01:11:22,589
Jagħmlu l-wisa 'ta' din il-paġna
effettiv daqs il-wisa 'apparat.

1528
01:11:22,589 --> 01:11:25,380
Fi kliem ieħor, ma jassumu li
inti għandek tip ta 'spazju mhux limitat.

1529
01:11:25,380 --> 01:11:29,920
Assumi inti biss għandek kemm
ispazju bħala l-mezz innifsu huwa kbir.

1530
01:11:29,920 --> 01:11:34,454
U hekk issa, jekk I rikarigu dan il
fil-browser tiegħi, nara ebda bidla.

1531
01:11:34,454 --> 01:11:37,370
Imma jekk jien għamilt dan correctly-- u
let me jaqsmu fingers-- tiegħi jekk inti kollha

1532
01:11:37,370 --> 01:11:42,920
rikarigu telefowns tiegħek, do inti
tara bidla konvinċenti?

1533
01:11:42,920 --> 01:11:43,620
Yeah, huwa that--

1534
01:11:43,620 --> 01:11:45,067
>> UDJENZA: [inaudible]

1535
01:11:45,067 --> 01:11:45,900
DAVID J. Malan: Iva.

1536
01:11:45,900 --> 01:11:46,400
KOLLOX SEW.

1537
01:11:46,400 --> 01:11:47,850
Allura forsi aktar leġġibbli issa?

1538
01:11:47,850 --> 01:11:53,070
Għadu żgħir, li tkun ġusta, iżda mhux
tant żgħar li jkunu maniġjabbli.

1539
01:11:53,070 --> 01:11:56,920
UI tista 'ċertament jiskarta din
ulterjuri ma CSS jew fuq in-naħa server,

1540
01:11:56,920 --> 01:12:00,120
imma dejjem dak li int
jaraw huwa aktar u aktar karatteristiċi

1541
01:12:00,120 --> 01:12:02,900
jiġu miżjuda mal
environments-- client-side

1542
01:12:02,900 --> 01:12:06,530
JavaScript, kif aħna ser jiddiskutu
għada, CSS, u HTML-- hekk

1543
01:12:06,530 --> 01:12:09,190
li kollha ta 'dawn mistoqsijiet
jista 'jsir fuq il-klijent

1544
01:12:09,190 --> 01:12:11,910
sabiex jolqot il-
servers ħafna inqas u mhux

1545
01:12:11,910 --> 01:12:14,530
li jkollhom biex ilaħħqu ma ', per
Pereżempju, l-onslaught kostanti

Verżjonijiet, verżjonijiet browser ġodda.

1547
01:12:17,210 --> 01:12:20,190
Tista 'biss let l-browser
jitlob lill-apparat, kemm hu kbir int,

1548
01:12:20,190 --> 01:12:22,890
u mbagħad jagħmlu kemmxejn loġiku
deċiżjonijiet ibbażati fuq dak.

1549
01:12:22,890 --> 01:12:25,140
Iżda aħna ser tara aktar opportunitajiet
għad-deċiżjonijiet loġiku

1552
01:12:29,800 --> 01:12:32,760
>> Allura, xi mistoqsijiet, imbagħad,
dwar l-iżvilupp tal-web?

1553
01:12:32,760 --> 01:12:36,130
Llum mhijiex programmazzjoni web, kull
se, peress li ħafna dak kollu li għamilna

1554
01:12:36,130 --> 01:12:38,370
kien estetika ħafna, jekk inti se.

1555
01:12:38,370 --> 01:12:41,750
M'hemm l-ebda teħid ta 'deċiżjonijiet fil
il-kodiċi li għandna bil-miktub,

1556
01:12:41,750 --> 01:12:44,990
u b'tali mod li għalhekk HTML hija markup
lingwa, mhux lingwa ta 'programmar.

1557
01:12:44,990 --> 01:12:47,140
Iżda għada aħna ser tagħti
ħarsa, finalment,

1566
01:13:08,754 --> 01:13:11,670

Hekk forsi biss tikkunsidra
mhux embarrassing yourself
