1
00:00:00,000 --> 00:00:01,291
>> DAVID J. Malan: Hivyo sisi ni nyuma.

2
00:00:01,291 --> 00:00:03,050
Hivyo kiwango cha juu cha
mada wakati sasa

3
00:00:03,050 --> 00:00:06,440
ni teknolojia mwingi, ambayo si
hasa kiufundi mrefu,

4
00:00:06,440 --> 00:00:09,960
ni zaidi ya kukamata wote kwa ajili ya yoyote
idadi ya mchanganyiko wa teknolojia

5
00:00:09,960 --> 00:00:11,840
kwamba unaweza kutumia ili kutatua matatizo.

6
00:00:11,840 --> 00:00:14,850
Na labda zaidi
njia ya kufaa kuanza

7
00:00:14,850 --> 00:00:18,110
itakuwa kuangalia lugha tangu
Mimi kuendelea rattling mbali rundo zima

8
00:00:18,110 --> 00:00:21,000
na wengi kila mtu katika chumba ina
pengine habari za angalau moja.

9
00:00:21,000 --> 00:00:25,730
>> Na hivyo kwa nini sio sisi kujaribu kutofautisha
what-- kutofautisha lugha hizi

10
00:00:25,730 --> 00:00:28,932
na majadiliano kwa ufupi juu wakati wewe ungekuwa
kuchagua moja juu ya nyingine, jinsi wao uko

11
00:00:28,932 --> 00:00:30,890
aina ya kimsingi
tofauti, na hasa

12
00:00:30,890 --> 00:00:34,830
wakati wewe ni kuzungumza na wahandisi,
au kujaribu kuamua nani wa kuajiri,

13
00:00:34,830 --> 00:00:37,652
au nini utekelezaji
pendekezo la Greenlight,

14
00:00:37,652 --> 00:00:39,860
jinsi gani kweli kufanya
aina wale wa maamuzi.

15
00:00:39,860 --> 00:00:41,890
>> Basi hebu tu njuga baadhi ya mambo mbali.

16
00:00:41,890 --> 00:00:45,300
Ya lugha ya watu wana
kusikia kuhusu, nini inakuja akilini?

17
00:00:45,300 --> 00:00:48,030
C. OK.

18
00:00:48,030 --> 00:00:48,757
OK, C ++.

19
00:00:48,757 --> 00:00:51,400

20
00:00:51,400 --> 00:00:51,990

Kipi kingine?

25
00:00:57,000 --> 00:00:58,810
Visual Basic.

26
00:00:58,810 --> 00:01:01,100

00:01:12,810 --> 00:01:13,770
katika swali.

33
00:01:13,770 --> 00:01:14,770
Na napenda kutaja kwamba.

34
00:01:14,770 --> 00:01:15,900
Hivyo tutaweza kuja nyuma na kwamba.

35
00:01:15,900 --> 00:01:17,560
Samahani?

36
00:01:17,560 --> 00:01:18,170
Pole?

Kwa kweli wangeweza kutumia SQL kama vile.

48
00:01:36,560 --> 00:01:38,360
Basi hebu kuweka kwamba baada ya
mapumziko vilevile.

49
00:01:38,360 --> 00:01:39,744

00:01:42,303 --> 00:01:46,150

54
00:01:46,150 --> 00:01:49,180

COBOL.

63
00:02:01,550 --> 00:02:02,410
Mimi itabidi toss nje BASIC.

Oh, kuwapiga yake.

70
00:02:12,248 --> 00:02:15,370

71
00:02:15,370 --> 00:02:15,870
Kitu chochote?

72
00:02:15,870 --> 00:02:18,700
Siwezi kufikiria michache ya wengine.

73
00:02:18,700 --> 00:02:21,876
Siwezi kufikiria wengine wachache.

74
00:02:21,876 --> 00:02:22,792
Na nini ilikuwa mwisho?

75
00:02:22,792 --> 00:02:23,970
>> Watazamaji: ASP.

00:02:25,030 --> 00:02:26,100
Yeah.

Active server kurasa.

79
00:02:27,100 --> 00:02:30,270
Kuwa kwa ujumla bila kuanguka chini ya
lugha nyingine, wakati mwingine C #,

80
00:02:30,270 --> 00:02:32,040
hivyo hebu kuondoka kwamba mbali.

81
00:02:32,040 --> 00:02:35,510
Lakini tutaweza kuja nyuma na kwamba
kwa mifumo na vile.

82
00:02:35,510 --> 00:02:36,290
Kitu kingine?

83
00:02:36,290 --> 00:02:39,020
PHP ni maarufu.

84
00:02:39,020 --> 00:02:41,710
Ruby ni mwingine.

85
00:02:41,710 --> 00:02:48,230
JavaScript, si kwa kuchanganyikiwa
na Java, ni mwingine.

86
00:02:48,230 --> 00:02:49,570
Hiyo ni aina ya mengi.

87
00:02:49,570 --> 00:02:53,590
>> Hivyo inaweza kuwa hakika balaa,
kana orodha ni si tayari,

88
00:02:53,590 --> 00:02:55,650
tu kuanza kujua wapi kuanza.

89
00:02:55,650 --> 00:02:58,130
Na hivyo kwa bahati nzuri, hebu
mbinu hii kutoka pembe chache.

90
00:02:58,130 --> 00:03:03,520
Kwanza, hebu jaribu kuainisha
angalau baadhi ya lugha hizi

91
00:03:03,520 --> 00:03:06,790
katika ndoo mbili pana, kukumbusha ya
mazungumzo tulikuwa kabla ya mapumziko,

92
00:03:06,790 --> 00:03:09,630
ambapo kuongelea kuandaa,
na kanuni chanzo, na mashine kanuni,

93
00:03:09,630 --> 00:03:11,440
kwa sababu si kwamba jinsi
lugha zote kazi.

94
00:03:11,440 --> 00:03:15,640
Hivyo tutaweza kuyang'oa mifano michache of--
au kukabiliana na examples-- kwa mfano kwamba.

95
00:03:15,640 --> 00:03:18,490
>> Na kisha, kwa nini sio sisi
majadiliano juu ya maombi

96
00:03:18,490 --> 00:03:20,390
kwamba lugha hizi
kwa ujumla kutumika kwa ajili ya.

97
00:03:20,390 --> 00:03:22,840
Na kusema ukweli, ingawa
hii ni orodha pretty muda mrefu,

98
00:03:22,840 --> 00:03:26,320
ni tu subset ya orodha hii kwamba
ungependa kawaida kuteka kutoka siku hizi

99
00:03:26,320 --> 00:03:27,220
kutatua matatizo.

100
00:03:27,220 --> 00:03:29,150
Baadhi ya lugha ni karibu zaidi kuliko wengine.

101
00:03:29,150 --> 00:03:31,170
Baadhi ya lugha ni
maarufu zaidi kuliko wengine.

102
00:03:31,170 --> 00:03:34,370
Hivyo si kama una hiyo
Kazi balaa kabla

103
00:03:34,370 --> 00:03:36,970
wakati wa kuamua miongoni mwa
hizi lugha mbalimbali.

104
00:03:36,970 --> 00:03:40,110
>> Basi hebu kufanya hili.

105
00:03:40,110 --> 00:03:45,870
Tulikuwa awali, chanzo kanuni,
na kisha tulikuwa mashine kanuni.

106
00:03:45,870 --> 00:03:48,590

107
00:03:48,590 --> 00:03:49,400
Whoops.

108
00:03:49,400 --> 00:03:50,910
Kuandika neno sahihi.

109
00:03:50,910 --> 00:03:52,740
Machine kanuni.

110
00:03:52,740 --> 00:03:57,549
Na tulikuwa na baadhi ya mchakato katika
katikati called-- yeah, compiler.

111
00:03:57,549 --> 00:03:58,215
Hivyo compiler.

112
00:03:58,215 --> 00:04:00,760

113
00:04:00,760 --> 00:04:03,910
>> Na nini kificho mashine
kweli anaendesha juu ya mwisho

114
00:04:03,910 --> 00:04:05,680
ni kwenda kuwa CPU yako halisi.

115
00:04:05,680 --> 00:04:09,660
Kwa maneno mengine, kwa mashine code, I
maana kiwango cha maelekezo ya chini

116
00:04:09,660 --> 00:04:11,330
kwamba CPU kweli anaelewa.

117
00:04:11,330 --> 00:04:15,100
Aidha, kutoa, hoja,
kuokoa, na shughuli kama hiyo.

118
00:04:15,100 --> 00:04:19,700
Na hivyo hii ni mfano wa kuigwa kwa nini
ujumla inayojulikana kama lugha ulioandaliwa.

119
00:04:19,700 --> 00:04:21,000
Pengine si ya kushangaza.

120
00:04:21,000 --> 00:04:23,550
>> Hivyo hii ni mfano wa kuigwa
kwa lugha ulioandaliwa.

121
00:04:23,550 --> 00:04:25,970
Lakini zinageuka kuna ya
kundi jingine la lugha

122
00:04:25,970 --> 00:04:32,650
aitwaye kutafsiriwa languages--
kufasiriwa languages--

123
00:04:32,650 --> 00:04:34,030
kwamba ni tofauti kidogo.

124
00:04:34,030 --> 00:04:41,660
Wewe kuandika katika chanzo kanuni, kukimbia
yao kupitia mkalimani,

125
00:04:41,660 --> 00:04:45,440
na kwamba mkalimani ni
nini anaendesha CPU.

126
00:04:45,440 --> 00:04:50,120
Kwa maneno mengine, nini huna
emit ni nini, inaonekana?

127
00:04:50,120 --> 00:04:50,980
Machine kanuni.

128
00:04:50,980 --> 00:04:54,290
zeros na ndio kwamba CPU
yenyewe hatimaye anaelewa.

129
00:04:54,290 --> 00:04:59,780
>> Hivyo katika toleo hili la kwanza na
lugha kama C, kama tuliona,

130
00:04:59,780 --> 00:05:02,040
wewe kuandika katika chanzo kanuni
hiyo ni arcane kidogo,

131
00:05:02,040 --> 00:05:05,300
lakini angalau ni aina ya Kiingereza-kama
na ni angalau someka

132
00:05:05,300 --> 00:05:06,780
mara moja kupata kutumika yake.

133
00:05:06,780 --> 00:05:10,100
You kukimbia kwa njia ya compiler na nje
kupata, hatimaye, zeros na ndio.

134
00:05:10,100 --> 00:05:11,340
>> Hiyo kurahisisha.

135
00:05:11,340 --> 00:05:12,839
Kuna baadhi ya hatua nyingine katika huko.

136
00:05:12,839 --> 00:05:15,530
Kwa kweli, kama wameweza milele kusikia
neno "mkutano lugha,"

137
00:05:15,530 --> 00:05:17,990
hiyo ni hatua moja mbele
zeros na ndio.

138
00:05:17,990 --> 00:05:20,949
Hiyo kidogo zaidi someka,
lakini bado pretty arcane.

139
00:05:20,949 --> 00:05:23,740
Na hivyo kuna hatua ya kati
ambazo, kwa kweli, kinachoendelea hapa.

140
00:05:23,740 --> 00:05:26,360
Lakini pato, hatimaye,
ni zeros hizo na ndio.

141
00:05:26,360 --> 00:05:28,990
>> Lakini katika kufasiriwa
dunia, ambapo una

142
00:05:28,990 --> 00:05:32,680
lugha ambazo ni kufasiriwa
lugha, wewe kweli ruka hatua hiyo.

143
00:05:32,680 --> 00:05:36,010
Kwa maneno mengine, wakati wewe kuandika
mpango, wewe tu mara moja kukimbia nayo.

144
00:05:36,010 --> 00:05:38,960
Huwezi kukusanya ni na
kisha kukimbia, kama mimi hapo awali.

145
00:05:38,960 --> 00:05:41,132
Wewe tu kuandika ni na kukimbia nayo.

146
00:05:41,132 --> 00:05:44,340
Na kama unataka kufanya mabadiliko ya haraka,
kufanya mabadiliko ya haraka na rerun yake.

147
00:05:44,340 --> 00:05:46,640
Hivyo hakuna hatua katikati hapa.

148
00:05:46,640 --> 00:05:50,840
>> Sasa, kwa mpango niliandika hapo awali,
ambayo ilikuwa hii "Hello World" mpango,

149
00:05:50,840 --> 00:05:53,660
waweza sababu
wonder-- au inawezekana sababu

150
00:05:53,660 --> 00:05:58,570
state-- hiyo haikuwa huo
kuteketeza kukusanya mpango wangu.

151
00:05:58,570 --> 00:06:00,337
Inaonekana wamefanya hivyo tu kama hiyo.

152
00:06:00,337 --> 00:06:02,170
Na kuna graphical
matoleo ya compilers.

153
00:06:02,170 --> 00:06:05,270
Mimi nina kutumia toleo arcane sana,
lakini unaweza kugonga kifungo kucheza

154
00:06:05,270 --> 00:06:07,887
na kwamba itakuwa kweli kufanya
mkusanyiko kwa ajili yenu.

155
00:06:07,887 --> 00:06:10,720
Nimekuwa ulioandaliwa mpango na kisha
tena, kuendesha, mimi tu kufanya hivyo.

156
00:06:10,720 --> 00:06:13,820
Na ni matokeo upande wa kushoto huko, "Hello!"

157
00:06:13,820 --> 00:06:15,530
Kwamba haionekani yote kutaabisha.

158
00:06:15,530 --> 00:06:19,920
Lakini wakati mipango yako ni
zaidi ya moja tu, mbili, tatu,

159
00:06:19,920 --> 00:06:25,470
nne, tano mistari ya muda mrefu, inaweza
kuchukua sekunde mbali zaidi kukusanya.

160
00:06:25,470 --> 00:06:28,310
Wakati mwingine hata dakika au
kidogo kabisa ya muda wa kukusanya.

161
00:06:28,310 --> 00:06:30,480
Baada ya yote, baadhi ya
bidhaa kubwa duniani

162
00:06:30,480 --> 00:06:35,040
ni mambo kama mifumo ya uendeshaji,
Microsoft Word, Microsoft Excel,

163
00:06:35,040 --> 00:06:39,070
ambayo inaweza kuwa mamia ya maelfu
au hata mamilioni ya mstari wa kanuni ya muda mrefu,

164
00:06:39,070 --> 00:06:41,300
na wale sio tu
mara moja kutekeleza.

165
00:06:41,300 --> 00:06:44,560
>> Aidha, kwenye mtandao, ni
kuwa mtindo wa kutumia

166
00:06:44,560 --> 00:06:47,600
tu kufasiriwa lugha,
katika sehemu kwa sababu wewe

167
00:06:47,600 --> 00:06:50,570
wanaweza kufanya mabadiliko kama developer
na kisha tu mara moja upya

168
00:06:50,570 --> 00:06:52,570
kisakuzi ukurasa na
mara moja kuona matokeo.

169
00:06:52,570 --> 00:06:56,160
Na hivyo HTML, wakati si
lugha ya programu,

170
00:06:56,160 --> 00:06:58,860
ni lugha hiyo kufasiriwa.

171
00:06:58,860 --> 00:07:00,770
Na tuliona kwamba athari sawa jana.

172
00:07:00,770 --> 00:07:04,070
Wewe tu upya ukurasa baada ya kufanya
mabadiliko katika Cloud9 and-- voila--

173
00:07:04,070 --> 00:07:05,560
unaweza kuona matokeo mapya.

174
00:07:05,560 --> 00:07:07,090
>> Basi nini tofauti hapa?

175
00:07:07,090 --> 00:07:13,190
Katika HTML, kukumbuka, tulikuwa na wazi HTML,
wazi kichwa, kichwa wazi, cheo karibu,

176
00:07:13,190 --> 00:07:15,250
karibu kichwa, wazi mwili, na kadhalika.

177
00:07:15,250 --> 00:07:19,149
Tulikuwa na yote haya vitambulisho kwamba sisi pretty
Mengi yamesemwa, kuwaambia browser nini cha kufanya.

178
00:07:19,149 --> 00:07:20,690
Hey browser, inakuja HTML ukurasa.

179
00:07:20,690 --> 00:07:22,170
Hey browser, inakuja cheo.

180
00:07:22,170 --> 00:07:24,429
Hey browser, inakuja baadhi
Nakala kwamba lazima kuwa na ujasiri.

181
00:07:24,429 --> 00:07:25,720
Na kisha kumweleza kinyume.

182
00:07:25,720 --> 00:07:27,330
Hey browser, hiyo ni yake
kwa ujasiri uso maandishi.

183
00:07:27,330 --> 00:07:28,830
Hey browser, hiyo ni kwa ajili ya mwili.

184
00:07:28,830 --> 00:07:29,740
Na kadhalika.

185
00:07:29,740 --> 00:07:31,130
>> Na hivyo ndivyo browser?

186
00:07:31,130 --> 00:07:33,170
browser ni tu mkalimani.

187
00:07:33,170 --> 00:07:36,090
Ni mpango kwamba mtu kama
Microsoft au Google ameandika,

188
00:07:36,090 --> 00:07:39,160
ambao lengo katika maisha ni
kusoma lugha, unaojulikana kama HTML,

189
00:07:39,160 --> 00:07:39,890
na kuifasiri.

190
00:07:39,890 --> 00:07:41,290
Juu hadi chini, kushoto na kulia.

191
00:07:41,290 --> 00:07:46,880
Na wakati wowote kisakuzi anaona wazi
bracket, cheo, karibu mabano,

192
00:07:46,880 --> 00:07:48,960
ni lazima kutafsiri kwamba
kama maana, loo, kwamba

193
00:07:48,960 --> 00:07:52,490
maana mimi lazima kuyaweka maneno haya njia
hapa juu kwa juu ya browser.

194
00:07:52,490 --> 00:07:55,700
>> Hivyo ni tu anafanya nini HTML code anasema.

195
00:07:55,700 --> 00:07:57,240
Lakini hakuna zeros na ndio.

196
00:07:57,240 --> 00:07:58,250
Hakuna kutungwa.

197
00:07:58,250 --> 00:07:58,890
You hakufanya hivyo.

198
00:07:58,890 --> 00:07:59,931
kisakuzi hakufanya hivyo.

199
00:07:59,931 --> 00:08:01,710
Ni tu si kushiriki.

200
00:08:01,710 --> 00:08:05,890
>> Hivyo katika roho ya haya yanayoendelea
mada, leo na jana,

201
00:08:05,890 --> 00:08:08,400
kwamba inaonekana kuwa kipengele ajabu.

202
00:08:08,400 --> 00:08:11,410
Wewe ila kanuni yako na kisha
kukimbia tu ni au kuifasiri.

203
00:08:11,410 --> 00:08:13,790
Hakuna hatua ya kati.

204
00:08:13,790 --> 00:08:15,690
Hakika kuna gharama?

205
00:08:15,690 --> 00:08:16,810
Hawawezi wote kuwa upsides.

206
00:08:16,810 --> 00:08:19,964
Hivyo kile anaweza gharama kuwa ni nani?

207
00:08:19,964 --> 00:08:20,940
>> Watazamaji: Nafasi.

208
00:08:20,940 --> 00:08:22,370
>> DAVID J. Malan: Nafasi.

209
00:08:22,370 --> 00:08:23,370
Hivyo, uhakika.

210
00:08:23,370 --> 00:08:26,920
Katika dunia ulioandaliwa, una
si tu ya awali chanzo kanuni,

211
00:08:26,920 --> 00:08:29,657
wewe ni pia kujenga na
kisha labda kuokoa

212
00:08:29,657 --> 00:08:31,740
mashine code--
zeros na ones-- na kwamba

213
00:08:31,740 --> 00:08:33,870
got kuchukua up baadhi ya kiasi cha nafasi.

214
00:08:33,870 --> 00:08:34,429
Kabisa.

215
00:08:34,429 --> 00:08:35,765
Hivyo ni gharama wewe nafasi zaidi.

216
00:08:35,765 --> 00:08:39,289

217
00:08:39,289 --> 00:08:39,789
Yeah?

218
00:08:39,789 --> 00:08:43,280
>> Watazamaji: Browsers nguvu
kutafsiri tofauti.

219
00:08:43,280 --> 00:08:46,770
>> DAVID J. Malan: Browsers nguvu
kutafsiri tofauti.

220
00:08:46,770 --> 00:08:48,622
Hiyo ni kweli.

221
00:08:48,622 --> 00:08:50,330
Lakini mimi nina uhakika mimi nina
vizuri wakidai

222
00:08:50,330 --> 00:08:51,840
hiyo ni kwa sababu ni kufasiriwa.

223
00:08:51,840 --> 00:08:56,340
Hiyo ni zaidi kwa sababu tu ni
utekelezaji wa lugha

224
00:08:56,340 --> 00:08:58,050
kwamba yenyewe ina utata.

225
00:08:58,050 --> 00:09:01,570
Hivyo basi si kabisa kuthibitisha
kwamba mmoja, lakini hunch nzuri.

226
00:09:01,570 --> 00:09:03,103
Nini kingine inaweza kuwa bei ya kulipwa?

227
00:09:03,103 --> 00:09:03,602
Andrew?

228
00:09:03,602 --> 00:09:05,912
>> Watazamaji: Wewe ni kuchanganya
hatua mbili, hivyo hiyo

229
00:09:05,912 --> 00:09:08,300
na kuongeza utata pia.

230
00:09:08,300 --> 00:09:11,040
>> DAVID J. Malan: complex--
kuongezeka kwa utata wapi?

231
00:09:11,040 --> 00:09:12,270
Kwa ajili ya nani?

232
00:09:12,270 --> 00:09:16,748
>> Watazamaji: Hivyo, katika mkalimani
hatua, wewe ni kuchanganya mkalimani

233
00:09:16,748 --> 00:09:19,120
na compiler kwa ajili tu kuongoza hadi to--

234
00:09:19,120 --> 00:09:21,100
>> DAVID J. Malan: Ah, OK.

235
00:09:21,100 --> 00:09:25,240
Suala la kushangaza, pengine ni kidogo
rahisi kutekeleza mkalimani,

236
00:09:25,240 --> 00:09:29,530
ingawa inaweza kuonekana
mavuno upsides ya urahisi hili.

237
00:09:29,530 --> 00:09:30,550
Hivyo uwezekano wa kweli.

238
00:09:30,550 --> 00:09:32,716
Lakini ni aina ya inategemea, mimi
kusema, juu ya lugha

239
00:09:32,716 --> 00:09:35,720
na juu ya jinsi walikwenda
kuhusu kuutekeleza.

240
00:09:35,720 --> 00:09:38,535
Kuna inaweza kuwa mengi zaidi utata,
kweli, katika compiler,

241
00:09:38,535 --> 00:09:41,410
kwa sababu tu una kwenda kutoka
kitu hivyo kiwango cha juu cha kitu

242
00:09:41,410 --> 00:09:42,560
hivyo ngazi ya chini.

243
00:09:42,560 --> 00:09:45,340
Lakini wazo nzuri.

244
00:09:45,340 --> 00:09:50,770
>> Hivyo kuweka njia nyingine, mpango ulioandaliwa,
wakati akageuka katika zeros hizo na ndio,

245
00:09:50,770 --> 00:09:54,470
mwisho juu katika lugha
kwamba CPU anaongea,

246
00:09:54,470 --> 00:09:57,850
ambapo katika upande huu wa
dunia, mpango umefanya imeandikwa,

247
00:09:57,850 --> 00:10:02,527
kificho umefanya imeandikwa, kamwe kweli
anapata waongofu katika lugha halisi

248
00:10:02,527 --> 00:10:03,360
kompyuta anaongea.

249
00:10:03,360 --> 00:10:04,190
zeros na ndio.

250
00:10:04,190 --> 00:10:08,480
Anakaa katika awali, binadamu zaidi
kirafiki, zaidi someka lugha.

251
00:10:08,480 --> 00:10:11,720
Hivyo kile anaweza kuwa na maana
kuna, kama wewe si kweli

252
00:10:11,720 --> 00:10:15,020
kujisumbua kuwabadili yako
mpango wa lugha sana

253
00:10:15,020 --> 00:10:18,013
kwamba kompyuta msingi anaongea?

254
00:10:18,013 --> 00:10:19,780
>> Watazamaji: Nguvu si
kuelewa kitu?

255
00:10:19,780 --> 00:10:21,170
>> DAVID J. Malan: Nguvu
hawaelewi kitu.

256
00:10:21,170 --> 00:10:23,297
Na kwamba inaweza claim--
kama hakuwa na kuelewa

257
00:10:23,297 --> 00:10:25,880
kitu, hiyo ni mdudu au ukosefu
ya kipengele katika mkalimani.

258
00:10:25,880 --> 00:10:28,544
Hivyo kwamba itakuwa zaidi ya
makosa ya gharama.

259
00:10:28,544 --> 00:10:30,419
>> Watazamaji: Unaweza kupata
chanzo kanuni?

260
00:10:30,419 --> 00:10:31,877
DAVID J. Malan: Kuna moja nzuri.

261
00:10:31,877 --> 00:10:34,140
Hivyo upande wa chini hapa ni wewe
Inaonekana kuwa na upatikanaji.

262
00:10:34,140 --> 00:10:37,006
Wewe, mtumiaji wa mwisho, inaweza kuonekana kwa
wanapata kanuni chanzo.

263
00:10:37,006 --> 00:10:38,130
Na kwamba ni si kweli daima.

264
00:10:38,130 --> 00:10:39,660
Lakini ni kweli katika
kesi ya JavaScript,

265
00:10:39,660 --> 00:10:41,660
ambayo tutaangalia baada
mapumziko leo, ambayo

266
00:10:41,660 --> 00:10:45,720
ni kufasiriwa lugha ya programu
kwamba kuandika katika chanzo kanuni.

267
00:10:45,720 --> 00:10:48,890
>> Lakini hiyo kanuni chanzo anapata kuhamishiwa
kutoka server yako na browser

268
00:10:48,890 --> 00:10:51,392
na anaendesha katika browser binadamu.

269
00:10:51,392 --> 00:10:54,350
Hivyo hapa anaweza tu kufungua
dirisha, kama nimekuwa kufanya katika Chrome,

270
00:10:54,350 --> 00:10:57,740
na ukiangalia hiyo, kama sisi wenyewe
akapiga katika jana na Google.

271
00:10:57,740 --> 00:11:00,420
Ni inaweza kuangalia kidogo
incomprehensible lakini ni huko.

272
00:11:00,420 --> 00:11:03,482
Hivyo hiyo ni kabisa moja bei ya kulipwa.

273
00:11:03,482 --> 00:11:04,565
Watazamaji: Utendaji hit?

274
00:11:04,565 --> 00:11:05,020
DAVID J. Malan: Yeah.

275
00:11:05,020 --> 00:11:06,260
Na kwamba ni biggie mengine.

276
00:11:06,260 --> 00:11:07,380
Kuna utendaji hit.

277
00:11:07,380 --> 00:11:10,100
Kwa sababu una hii
mtu katikati, ambayo yenyewe

278
00:11:10,100 --> 00:11:13,740
ni mpango, kati ya wewe
na CPU, kinyume

279
00:11:13,740 --> 00:11:17,880
tu kulisha hivi mbichi
zeros na ndio katika CPU,

280
00:11:17,880 --> 00:11:21,060
kuna utendaji hit kwamba
kuchukua na lugha kufasiriwa.

281
00:11:21,060 --> 00:11:24,240
Vile kwamba, kiholela, mpango
ambayo inaweza kuchukua moja ya pili

282
00:11:24,240 --> 00:11:27,840
kuendesha kwenye kompyuta au moja
dakika ya kuendesha kwenye kompyuta hapa,

283
00:11:27,840 --> 00:11:32,059
inaweza kuchukua sekunde 10 au 10
dakika ya kuendesha kwenye kompyuta hapa.

284
00:11:32,059 --> 00:11:35,100
Ni kwa ujumla si kwenda kuwa kwamba
mengi ya sababu difference-- ya 10--

285
00:11:35,100 --> 00:11:36,808
kwa sababu kuna
optimizations unaweza kufanya.

286
00:11:36,808 --> 00:11:38,680
Lakini ni karibu kila mara polepole.

287
00:11:38,680 --> 00:11:43,070
Sasa, hasara kwa wasiwasi wake kuwa
ni kwamba, vizuri kompyuta, kila 12

288
00:11:43,070 --> 00:11:45,970
hadi 18 months-- kulingana na
sheria Moore, hivyo kusema

289
00:11:45,970 --> 00:11:47,600
ni kupata tu kasi na kasi.

290
00:11:47,600 --> 00:11:48,750
Nina zaidi na zaidi disk nafasi.

291
00:11:48,750 --> 00:11:49,791
Nina RAM zaidi na zaidi.

292
00:11:49,791 --> 00:11:50,620
Ambao kwa kweli wasiwasi?

293
00:11:50,620 --> 00:11:52,328
>> Na hiyo ni aina ya
busara hoja.

294
00:11:52,328 --> 00:11:55,740
Hakika, moja ya sababu
kwa nini hatuwezi kuvumilia polepole

295
00:11:55,740 --> 00:11:58,480
kufasiriwa lugha ni kwa sababu
sisi binadamu si kweli taarifa.

296
00:11:58,480 --> 00:12:00,690
kompyuta na
wamezipata hivyo tu darn haraka.

297
00:12:00,690 --> 00:12:04,520
Wakati nyuma katika siku, hasa
wakati vifaa ilikuwa mengi zaidi unakabiliwa,

298
00:12:04,520 --> 00:12:06,860
wewe alikuwa chini ya kila kitu,
ilikuwa ni ghali zaidi

299
00:12:06,860 --> 00:12:10,570
hivyo kila kitu gharama zaidi, vizuri basi
kweli alitaka itapunguza nje

300
00:12:10,570 --> 00:12:12,590
utendaji kama vile wewe unaweza.

301
00:12:12,590 --> 00:12:16,400
Lakini hiyo wanatakiwa kuandika katika
ngazi ya chini, kama wewe,

302
00:12:16,400 --> 00:12:18,090
na lugha ulioandaliwa.

303
00:12:18,090 --> 00:12:20,830
>> Hivyo kufanya kuchukua hii hit utendaji.

304
00:12:20,830 --> 00:12:24,780
Lakini kwa ujumla, upsides
wanaonekana kuwa na thamani yake siku hizi.

305
00:12:24,780 --> 00:12:26,850
Naam, isipokuwa kwa
miliki suala hilo.

306
00:12:26,850 --> 00:12:28,641
Kwamba aina ya readability
wa kanuni, tutaweza

307
00:12:28,641 --> 00:12:30,640
kurudi tunapoangalia JavaScript.

308
00:12:30,640 --> 00:12:33,140
>> Basi hebu jaribu kuainisha
angalau wachache wa haya.

309
00:12:33,140 --> 00:12:41,650
Hivyo kati ya lugha ulioandaliwa, sisi
ingekuwa C, C ++, kinda, sorta, Java,

310
00:12:41,650 --> 00:12:48,120
ingawa ni kidogo ya ubaguzi, kwa
sababu mimi nitakuonyesha katika muda tu.

311
00:12:48,120 --> 00:12:51,540
C # itakuwa kwenye orodha hii.

312
00:12:51,540 --> 00:12:54,930
Tutaangalia zaidi saa tu
lugha ya kisasa zaidi.

313
00:12:54,930 --> 00:12:55,430
Sawa.

314
00:12:55,430 --> 00:12:56,804
Na kwamba inaonekana kama mengi huko.

315
00:12:56,804 --> 00:13:03,500
Wakati upande huu wa uzio,
tupate kuwa na JavaScript, na chatu,

316
00:13:03,500 --> 00:13:08,040
na PHP, na Ruby.

317
00:13:08,040 --> 00:13:13,640
Na ni kwamba kutosha kwa ajili ya
ndio hivi karibuni zaidi?

318
00:13:13,640 --> 00:13:15,410
Kwamba anahisi kama mengi kwa sasa.

319
00:13:15,410 --> 00:13:16,330
SAWA.

320
00:13:16,330 --> 00:13:18,760
Na kisha dot dot dot,
tangu orodha ni kutokuwa na mwisho.

321
00:13:18,760 --> 00:13:22,300
>> Na kwa kweli, kama tunataka tu
kupata hisia ya Haya Wikipedia,

322
00:13:22,300 --> 00:13:24,130
ulioandaliwa lugha.

323
00:13:24,130 --> 00:13:27,150
Mimi guessing tunaweza kupata
mbali zaidi orodha kamili.

324
00:13:27,150 --> 00:13:27,910
Hivyo hapa sisi kwenda.

325
00:13:27,910 --> 00:13:30,620
Hivyo hapa ni orodha mengi zaidi kamilifu.

326
00:13:30,620 --> 00:13:34,150
Na Mimi nilikuwa na matumaini mtu bila nadhani D
kama lugha kwa sababu hiyo pia ipo,

327
00:13:34,150 --> 00:13:37,747
lakini wao kusimamishwa katika D inaweza kuonekana.

328
00:13:37,747 --> 00:13:39,330
Ingawa huenda kuna kweli kuwa E.

329
00:13:39,330 --> 00:13:41,496
>> Oh, kwa kweli, hii lazima
kuwa katika orodha ya siku hizi.

330
00:13:41,496 --> 00:13:47,460
Swift ni kweli
lugha ambayo Apple zuliwa

331
00:13:47,460 --> 00:13:50,302
kwamba sasa ni kutumika, inazidi
hivyo, katika maendeleo iPhone.

332
00:13:50,302 --> 00:13:52,260
Lakini tutaweza kurudi kwa
kwamba pamoja na mjadala wetu

333
00:13:52,260 --> 00:13:54,090
ya simu katika kidogo tu kama vile.

334
00:13:54,090 --> 00:13:55,260
Hivyo Swift pia.

335
00:13:55,260 --> 00:13:57,540
>> Na kisha kama sisi kwenda
kufasiriwa language--

336
00:13:57,540 --> 00:14:05,010
kufasiriwa language-- basi hapa ni
orodha hata tena kama vile.

337
00:14:05,010 --> 00:14:07,260
Hivyo kama wewe tu google na
kuangalia juu ya Wikipedia kwa haya,

338
00:14:07,260 --> 00:14:09,231
utaona kila aina ya lugha.

339
00:14:09,231 --> 00:14:10,980
Lakini lengo ni,
kwa leo kweli, tu

340
00:14:10,980 --> 00:14:13,680
majipu chini labda hii
Suala la haki miliki

341
00:14:13,680 --> 00:14:18,200
na readability na mtumiaji wa mwisho na kwa
utendaji, ni biggie nyingine pia.

342
00:14:18,200 --> 00:14:21,080
>> Hivyo kati ya lugha hizi,
napenda kuona kama tunaweza kukupa

343
00:14:21,080 --> 00:14:24,487
baadhi tu ya sampuli ya lugha.

344
00:14:24,487 --> 00:14:26,820
Hatutaki kupitia
lugha zote ukomo.

345
00:14:26,820 --> 00:14:29,720
Je, umewahi kujiuliza kwa nini a
lugha fulani inaonekana kama?

346
00:14:29,720 --> 00:14:31,562
Sisi alifanya kuona wakati iliyopita.

347
00:14:31,562 --> 00:14:33,520
Mbona sisi kuchukua michache
ya kipengele maombi.

348
00:14:33,520 --> 00:14:35,380
Ambao wangependa kuona nini
lugha nyingine inaonekana kama?

349
00:14:35,380 --> 00:14:35,620
Yeah.

350
00:14:35,620 --> 00:14:36,150
>> Watazamaji: Java.

351
00:14:36,150 --> 00:14:36,540
>> DAVID J. Malan: Java.

352
00:14:36,540 --> 00:14:37,040
Sawa.

353
00:14:37,040 --> 00:14:38,504
Basi hebu kwenda kwa Java.

354
00:14:38,504 --> 00:14:42,300

355
00:14:42,300 --> 00:14:44,900
Na tu kukupa sample--
tunaweza kuandika haya yote nje,

356
00:14:44,900 --> 00:14:47,670
lakini itakuwa kwa kasi tu
kuangalia sampuli kificho mtu mwingine.

357
00:14:47,670 --> 00:14:48,170
Sawa.

358
00:14:48,170 --> 00:14:50,330
Kwa hiyo ni mfano mzuri?

359
00:14:50,330 --> 00:14:52,040
Whoops.

360
00:14:52,040 --> 00:14:52,540
SAWA.

361
00:14:52,540 --> 00:14:58,810
Hivyo hapa ni Java toleo la
mpango niliandika hapo awali, "Hello World."

362
00:14:58,810 --> 00:15:01,900
>> Hivyo Java, utasikia mara nyingi
angalia keyword "darasa."

363
00:15:01,900 --> 00:15:03,779
Basi utaona baadhi jina baada ya hapo.

364
00:15:03,779 --> 00:15:05,570
Utaona braces curly
kama tuliona kabla,

365
00:15:05,570 --> 00:15:08,153
na wakati mwingine wao kwenda kwenye
mstari huo huo, mistari wakati mwingine wengine,

366
00:15:08,153 --> 00:15:09,734
ni aina ya uamuzi binafsi.

367
00:15:09,734 --> 00:15:11,900
Utaona maneno kama
"Ya umma," "tuli", "batili."

368
00:15:11,900 --> 00:15:13,790
Lakini hatukuwa kuona "kuu."
"Kuu" kwa ujumla ni

369
00:15:13,790 --> 00:15:17,220
jina la kazi default
au default chunk ya kificho kwamba

370
00:15:17,220 --> 00:15:18,760
anapata kukimbia katika mpango.

371
00:15:18,760 --> 00:15:19,330
>> "Kamba."

372
00:15:19,330 --> 00:15:20,850
Je, maana sisi na kamba mapema?

373
00:15:20,850 --> 00:15:23,480
Nilikuwa ni aina ya kawaida.

374
00:15:23,480 --> 00:15:25,100
kamba ni nini?

375
00:15:25,100 --> 00:15:25,601
Neno.

376
00:15:25,601 --> 00:15:27,058
Ni kama mlolongo wa wahusika.

377
00:15:27,058 --> 00:15:29,810
wahusika binafsi, nyuma ya
nyuma kwa nyuma, kwa kawaida katika safu,

378
00:15:29,810 --> 00:15:30,690
kama tumekuwa kujadiliwa.

379
00:15:30,690 --> 00:15:34,700
Na kwa kweli, angalia syntax hii
hapa, mabano mraba mbili?

380
00:15:34,700 --> 00:15:39,210
Hii ina maana, hey kompyuta, hapa
inakuja safu ya masharti.

381
00:15:39,210 --> 00:15:42,636
mraba bracket nukuu ni
kawaida kutumika kuashiria kwamba.

382
00:15:42,636 --> 00:15:44,510
Na kisha pengine unaweza
kuchukua guess-- nini

383
00:15:44,510 --> 00:15:46,580
gani hii yalionyesha
chunk ya kificho pengine kufanya?

384
00:15:46,580 --> 00:15:49,737

385
00:15:49,737 --> 00:15:50,639
>> Watazamaji: pato?

386
00:15:50,639 --> 00:15:51,090
>> DAVID J. Malan: Yeah.

387
00:15:51,090 --> 00:15:52,506
Ni Prints kitu screen.

388
00:15:52,506 --> 00:15:57,070
Hivyo "mfumo" ni aina ya
kumbukumbu ya kompyuta yako.

389
00:15:57,070 --> 00:15:59,620
"Kati" maana yake kompyuta yako
pato au screen.

390
00:15:59,620 --> 00:16:04,450
Hivyo "system.out.print ln" pengine maana yake?

391
00:16:04,450 --> 00:16:05,570
"Ln."

392
00:16:05,570 --> 00:16:09,570
Magazeti line ambayo programmers kama
kwa inaonekana Spell baadhi ya maneno nje

393
00:16:09,570 --> 00:16:11,820
katika ukamilifu wao na kuchukua
shortcuts kwa maneno mengine.

394
00:16:11,820 --> 00:16:13,260
Lakini "ln" ni mstari, hivyo line magazeti.

395
00:16:13,260 --> 00:16:17,370
Hivyo ni Prints nje "Hello
Dunia! "Ikifuatiwa na mstari mpya.

396
00:16:17,370 --> 00:16:18,300
>> Hivyo hiyo ni yake.

397
00:16:18,300 --> 00:16:21,150
Lakini Java ni nini wao itabidi
wito kitu-oriented.

398
00:16:21,150 --> 00:16:23,440
Na hakika, tu kutoa
michache ya ufafanuzi mengine

399
00:16:23,440 --> 00:16:26,420
pale kwamba waweza
kuona, kwa ujumla, kuna

400
00:16:26,420 --> 00:16:30,600
watu wengi aina mbalimbali za
lugha, lakini ya kawaida

401
00:16:30,600 --> 00:16:37,830
ni kiutaratibu au muhimu lugha.

402
00:16:37,830 --> 00:16:41,600
Kuna kazi
lugha, ambayo haina

403
00:16:41,600 --> 00:16:43,790
maana kwamba wengine ni nonfunctional.

404
00:16:43,790 --> 00:16:47,740
Na kisha kuna
kitu-oriented lugha.

405
00:16:47,740 --> 00:16:51,170
Na hii ni labda bora
categorization ya lugha nyingi

406
00:16:51,170 --> 00:16:56,445
kwamba ungependa milele kuchagua kwa aina
ya mradi kawaida ya kibiashara.

407
00:16:56,445 --> 00:16:58,910
>> Hii itakuwa sana ya,
Nadhani, ya shimo panya ya

408
00:16:58,910 --> 00:17:01,620
kwenda chini, ili kujaribu kueleza
tofauti mbalimbali.

409
00:17:01,620 --> 00:17:04,599
lakini lugha
tumeona hivi far-- C

410
00:17:04,599 --> 00:17:07,680
ni kiutaratibu au
lugha muhimu.

411
00:17:07,680 --> 00:17:11,200
Hivi karibuni zaidi zuliwa
Lugha huwa na kuwa, sorry,

412
00:17:11,200 --> 00:17:14,430
kitu-oriented, ambayo ina maana
wao kuwa na sifa nyingine kwao.

413
00:17:14,430 --> 00:17:18,130

414
00:17:18,130 --> 00:17:19,430
Naweza kueleza ni kwa njia hii?

415
00:17:19,430 --> 00:17:20,950
Hebu hata kwenda chini huko.

416
00:17:20,950 --> 00:17:25,200
>> Kitu-oriented njia
unaweza implement--

417
00:17:25,200 --> 00:17:27,930
unaweza mfano ulimwengu wa kweli
kidogo kwa ufanisi zaidi.

418
00:17:27,930 --> 00:17:29,722
Ubinadamu, baada ya muda,
ina figured nje, wow,

419
00:17:29,722 --> 00:17:32,430
itakuwa nzuri kama lugha yangu
alikuwa kipengele hiki au kwamba kipengele.

420
00:17:32,430 --> 00:17:34,830
Na kwamba ni kwa nini tuna hivyo
lugha nyingi duniani.

421
00:17:34,830 --> 00:17:37,670
Watu busara, smart
watu, kukubaliana au kutokubaliana

422
00:17:37,670 --> 00:17:41,000
na invariably aina ya kuja pamoja juu ya
kuendeleza lugha mpya wote pamoja.

423
00:17:41,000 --> 00:17:41,660
>> Uchunguzi katika kumweka.

424
00:17:41,660 --> 00:17:45,260
Apple zuliwa Swift katika
matumaini ya labda kupunguza

425
00:17:45,260 --> 00:17:47,950
bar maendeleo iPhone,
kwa sababu language-- uliopita

426
00:17:47,950 --> 00:17:51,080
aitwaye Lengo-C, ambayo inaweza
pia kuwa katika orodha yetu here--

427
00:17:51,080 --> 00:17:54,190
ilikuwa zaidi arcane na mengi
vigumu wrap akili ya mtu kote.

428
00:17:54,190 --> 00:17:57,690
Na kama programu ni kuwa arguably
zaidi kupatikana na zaidi kwa upana

iliyopitishwa na watu hata
chini ya kiufundi, goal--

430

00:18:04,160 --> 00:18:07,400
lugha wenyewe
rahisi ya kupata ilianza na,

00:18:10,560 --> 00:18:14,110
Mbona sisi tuangalie
katika kitu kama chatu,

Hivyo hii ni kweli aina ya furaha.

447
00:18:41,283 --> 00:18:43,330
Hivyo kama wewe milele google
"Hello World," ambayo

448
00:18:43,330 --> 00:18:47,000
hutokea kwa kuwa moja ya mipango ya kwanza
milele imeandikwa katika lugha ya kisasa,

449
00:18:47,000 --> 00:18:51,830
tu kama ushahidi wa dhana, unaweza kuona
kila aina ya utekelezaji wa hii.

moja mimi kujifunza miaka iliyopita, katika sehemu.

yote ya mistari yako.

454
00:19:03,710 --> 00:19:05,626
Si tofauti na kile Mimi nilikuwa
kufanya wakati mimi nilikuwa kuandika

00:19:05,626 --> 00:19:08,380
pseudocode juu ya hati njano
mapema kwa ajili ya kutafuta binary,

ungependa literally aina,
kwenda 10, au kwenda 20.

459
00:19:15,780 --> 00:19:19,110
Na kama wewe ni kuandika mistari,
mkataba ulikuwa ni kufanya, hii ni mstari wa 10,

460
00:19:19,110 --> 00:19:22,545
hii ni mstari 20, hii ni mstari
30, 40, na kitu katika kati,

461
00:19:22,545 --> 00:19:25,170
hivyo kutoa mwenyewe baadhi chumba
kama wewe kuamua, kusubiri dakika,

462
00:19:25,170 --> 00:19:27,230
Mimi ni lazima kuwa aliongeza baadhi
zaidi kificho mahali fulani.

00:19:27,230 --> 00:19:30,960
Bado alikuwa na aina ya nafasi tisa kwa
itapunguza kwamba katika kati ya mpango wako

safu mpya juu ya kwamba

hivyo kwamba huna kuwa na wasiwasi
kuhusu nini mstari idadi kanuni yako

00:20:22,540 --> 00:20:23,200
SAWA.

487
00:20:23,200 --> 00:20:24,690
Hiyo ni kweli.

488
00:20:24,690 --> 00:20:26,440
Hivyo sisi ni kuzungumza juu ya C #.

489
00:20:26,440 --> 00:20:29,230
C # huelekea kutumika katika
Windows mazingira,

490
00:20:29,230 --> 00:20:33,550
hivyo kama wewe ni kuandika programu ya Microsoft
kwa Windows, C # ni kawaida sana kutumika,

491
00:20:33,550 --> 00:20:38,560
kama ni kwa ajili ya programu desktop, au
hata programu ya simu kwenye simu za Windows,

492
00:20:38,560 --> 00:20:41,820
kama umeshapata hizo,
au kwenye mtandao hata pia.

493
00:20:41,820 --> 00:20:44,642
Na kwa kweli, labda Kareem
zilizotajwa ASP mapema?

494
00:20:44,642 --> 00:20:46,600
Hivyo kuna pia hivi
mambo kuitwa mifumo,

495
00:20:46,600 --> 00:20:51,040
ambayo tunaweza kuanzisha kwa ugani.

496
00:20:51,040 --> 00:20:53,280
Mifumo, kama ASP.

497
00:20:53,280 --> 00:20:55,740
Anasimama kwa kurasa kazi server.

498
00:20:55,740 --> 00:20:59,880
Na hii ni kanuni na
njia ya programu

499
00:20:59,880 --> 00:21:03,490
kuwa kwa ujumla inafanya kuwa rahisi
kuandika maombi ya mtandao msingi.

500
00:21:03,490 --> 00:21:07,530
Kwa maneno mengine, itakuwa super,
super annoying kuandika tovuti

501
00:21:07,530 --> 00:21:09,469
katika lugha C kwamba
tumeona kabla,

502
00:21:09,469 --> 00:21:12,510
kwa sababu ingekuwa kutumia magazeti + F,
ingekuwa kutumia kwamba keyword

503
00:21:12,510 --> 00:21:13,940
"Kuu" na braces curly.

504
00:21:13,940 --> 00:21:16,720
mengi ya syntax arcane
na mbinu za kutekeleza

505
00:21:16,720 --> 00:21:19,195
kitu ambacho ni haki tata.

506
00:21:19,195 --> 00:21:20,240
mtandao ukurasa.

507
00:21:20,240 --> 00:21:23,800
>> Na hivyo lugha nyingine utvecklats
kufanya jambo la aina hiyo rahisi.

508
00:21:23,800 --> 00:21:26,890
Na kwa upande wake, watu wamekuja
na mifumo, aina ya zana

509
00:21:26,890 --> 00:21:30,520
kwamba unaweza kutumia kwamba kufanya hivyo ni
hata rahisi kuandika kurasa za mtandao.

510
00:21:30,520 --> 00:21:33,070
Hivyo kwa mfano, ili kufanya
hii ya saruji mengi zaidi,

511
00:21:33,070 --> 00:21:36,390
basi mimi kufungua tu
Nakala faili kwa muda.

512
00:21:36,390 --> 00:21:39,380
>> Na unaweza kukumbuka jana
kwamba sisi alisema kitu

513
00:21:39,380 --> 00:21:41,210
kama, hii ni ukurasa wa mtandao.

514
00:21:41,210 --> 00:21:42,300
HTML.

515
00:21:42,300 --> 00:21:45,340
Close HTML.

516
00:21:45,340 --> 00:21:48,500
Hebu ruka kichwa na
tu kufanya mwili hapa.

517
00:21:48,500 --> 00:21:52,810
Tuseme kwamba nilitaka
kuandika si "Hello World,"

518
00:21:52,810 --> 00:21:57,020
lakini "Hello David," ambapo yule Daudi yuko
jina la sasa watumiaji katika user.

519
00:21:57,020 --> 00:22:00,270
Nini kitu kama
ASP atafanya, au JSP--

520
00:22:00,270 --> 00:22:04,060
ambayo ni Java server pages-- au
idadi yoyote ya mifumo nyingine

521
00:22:04,060 --> 00:22:05,435
ni wao siyo lugha, per se.

522
00:22:05,435 --> 00:22:07,351
Wao ni tu kama
programu ya ziada kwamba wewe

523
00:22:07,351 --> 00:22:10,490
itakuwa kufunga katika mazingira yako
kwamba tu iwe rahisi kwa mpango.

524
00:22:10,490 --> 00:22:15,670
>> Hivyo kwa mfano, badala ya kuwa na kufanya
kitu kama "hello, printf (" David ")"

525
00:22:15,670 --> 00:22:17,510
au kitu ambacho ni
aina ya ushirikiano mingling--

526
00:22:17,510 --> 00:22:20,840
aina ya kificho tumeona kabla,
ungependa kufanya kitu rahisi sana,

527
00:22:20,840 --> 00:22:26,190
kama "jina%."

528
00:22:26,190 --> 00:22:28,660
Na hivyo mifumo hii,
kama ASP-- na mimi

529
00:22:28,660 --> 00:22:31,212
sikumbuki kama mimi nina kupata
syntax haki tu kwa ajili ASP.

530
00:22:31,212 --> 00:22:33,100
JSP ni little-- ni haki hii?

531
00:22:33,100 --> 00:22:36,500
>> Hivyo, pamoja na ASP, hii ni
aina ya syntax maalum

532
00:22:36,500 --> 00:22:39,830
kwamba baadhi ya watengenezaji wameamua
hii inaweza kuwasaidia watu nje.

533
00:22:39,830 --> 00:22:43,000
Na siwezi kueleza kwa ufupi zaidi
placeholders, kwa mfano.

534
00:22:43,000 --> 00:22:47,187
Kama kuweka thamani hapa, ambapo
hii jina thamani ya kitu si N-A-M-E,

535
00:22:47,187 --> 00:22:48,520
ni baadhi ya thamani kuhifadhiwa katika huko.

536
00:22:48,520 --> 00:22:50,728
Hivyo "jina," katika hali hii,
tunataka kuwaita kutofautiana.

537
00:22:50,728 --> 00:22:52,760
Algebra ina vigezo
kama x, na y, na z.

538
00:22:52,760 --> 00:22:56,021
Programmers kutumia vigezo kwamba ni
maelezo zaidi ya x, y, na z,

539
00:22:56,021 --> 00:22:56,520
kawaida.

540
00:22:56,520 --> 00:23:01,020
Hivyo "jina" ingekuwa literally kuwa baadhi ya aina
ya kumbukumbu chombo kwa kitu kama

541
00:23:01,020 --> 00:23:05,440
D-A-V-I-D, kwa jina langu, au mtu
mwingine ni watumiaji katika tovuti.

542
00:23:05,440 --> 00:23:09,300
>> Na hivyo hii ni aina ya urahisi
kupata na mazingira fulani.

543
00:23:09,300 --> 00:23:14,220
Hivyo C # na kitu kama ASP ingekuwa sana
kawaida kutumika katika dunia Windows,

544
00:23:14,220 --> 00:23:16,460
iwe ya desktop wake
programu au mtandao wa kompyuta,

545
00:23:16,460 --> 00:23:21,490
hasa kama seva yako ni kwa upande
mbio Microsoft Windows na Microsoft

546
00:23:21,490 --> 00:23:25,810
IIS-- au Internet Habari
Server, kama mimi kupata kifupi right--

547
00:23:25,810 --> 00:23:27,800
ambayo ni Microsoft mtandao wa kompyuta.

548
00:23:27,800 --> 00:23:30,820
>> Kwa hiyo kile lugha nyingine
ni folks ukoo na,

549
00:23:30,820 --> 00:23:35,228
au umesikia wa
mara nyingi zaidi kuliko?

550
00:23:35,228 --> 00:23:38,262
>> Watazamaji: Najua kwamba Python
aina ya maarufu [inaudible].

551
00:23:38,262 --> 00:23:39,470
DAVID J. Malan: maarufu sana.

552
00:23:39,470 --> 00:23:45,490
Hivyo Python hapa ni kutumika mara nyingi sana
katika maombi ya kisayansi au data

553
00:23:45,490 --> 00:23:48,330
sayansi, ambapo una mengi
ya data kwamba unataka kuchambua

554
00:23:48,330 --> 00:23:50,413
na unataka kutumia
lugha ya programu kwa ajili yake.

555
00:23:50,413 --> 00:23:53,640
R inaweza kawaida kutumika kwa ajili ya kwamba
pia, katika mazingira takwimu.

556
00:23:53,640 --> 00:23:56,400
Lakini Python ina wengi
makala kujengwa katika.

557
00:23:56,400 --> 00:23:58,850
Hivyo nyingi za ziada
maktaba, kama watu wanavyosema.

558
00:23:58,850 --> 00:24:01,260
>> Maktaba ni makusanyo tu
wa kanuni kwamba watu wengine

559
00:24:01,260 --> 00:24:04,218
aliandika kwamba unaweza kutumia ili uweze
hawana reinvent gurudumu hizo.

560
00:24:04,218 --> 00:24:07,430
Na hivyo chatu ni kawaida sana
kutumika katika maombi data sayansi.

561
00:24:07,430 --> 00:24:09,930
Lakini pia ni kawaida sana
kutumika katika maombi ya mtandao.

562
00:24:09,930 --> 00:24:12,780
Unaweza kutekeleza nguvu
tovuti kwa kutumia Python.

563
00:24:12,780 --> 00:24:15,210
>> Na kwa tovuti ya nguvu, I
maana maudhui si tu tuli

564
00:24:15,210 --> 00:24:19,530
kama sisi aliumba jana, na
bidii tu coding katika Amerika ya maandishi

565
00:24:19,530 --> 00:24:21,820
na mambo mengine kama hayo,
lakini badala ya uwezo

566
00:24:21,820 --> 00:24:25,367
kuingia katika, uwezo wa kununua
kitu, uwezo wa kuangalia nje ya

567
00:24:25,367 --> 00:24:26,950
na ununuzi mikokoteni yako, au kama.

568
00:24:26,950 --> 00:24:30,590
Yote hayo inahitaji mabadiliko na wewe
haja ya baadhi ya lugha kama mojawapo la hayo.

569
00:24:30,590 --> 00:24:35,060
>> Watazamaji: Hivyo haina Python na yake mwenyewe
ugani, sawa na kama [inaudible]

570
00:24:35,060 --> 00:24:36,060
DAVID J. Malan: Ni anafanya.

571
00:24:36,060 --> 00:24:42,250
Hivyo katika ulimwengu wa Python, Django ni
mfumo maarufu sana kwa chatu.

572
00:24:42,250 --> 00:24:46,520
WSGI ni utaratibu mwingine hiyo ni
aina ya tofauti na hii

573
00:24:46,520 --> 00:24:47,640
lakini sawa katika roho.

574
00:24:47,640 --> 00:24:52,200
Ni add-on kwamba inaruhusu
kuendesha Python kanuni ya server.

575
00:24:52,200 --> 00:24:53,950
Kuna other-- yeah.

576
00:24:53,950 --> 00:24:57,250
Basi hizi tutaweza wito mifumo hiyo.

577
00:24:57,250 --> 00:24:58,870
Na ni kidogo ya unyanyasaji.

578
00:24:58,870 --> 00:25:00,920
Hii ni zaidi ya teknolojia mtandao wa kompyuta.

579
00:25:00,920 --> 00:25:04,610
Lakini tutaweza kushika ni rahisi na kuweka
hivyo katika safu hii hata hivyo.

580
00:25:04,610 --> 00:25:05,780
>> SAWA.

581
00:25:05,780 --> 00:25:07,850
WSGI.

582
00:25:07,850 --> 00:25:09,020
WSGI.

583
00:25:09,020 --> 00:25:12,100
Mwingine thing-- na kweli, basi
mimi hoja kwamba kwa safu yake mwenyewe,

584
00:25:12,100 --> 00:25:17,000
kwa sababu napenda yell saa yangu kwa
kuwaweka katika ndoo moja.

585
00:25:17,000 --> 00:25:24,910
Hebu kuweka hii katika server
makala, hebu sema.

586
00:25:24,910 --> 00:25:26,710
Hiyo si kiufundi mrefu.

587
00:25:26,710 --> 00:25:29,180
>> Hivyo hapa sisi inaweza kuwa WSGI.

588
00:25:29,180 --> 00:25:32,580
Kuna CGI, ambayo ni mkubwa
mbinu kwa ajili ya kuwahudumia up lugha

589
00:25:32,580 --> 00:25:35,890
kama Perl au PHP, au baadhi ya wengine.

590
00:25:35,890 --> 00:25:39,000
Tena, nimekuwa zilizotajwa maneno haya
sio sana kwa aina ya ingrain yao,

591
00:25:39,000 --> 00:25:40,749
lakini ili kwamba kama unaweza kuona
nao ni kitu

592
00:25:40,749 --> 00:25:42,130
wewe tu google kusoma zaidi.

593
00:25:42,130 --> 00:25:46,110
Hakuna juisi halisi
kwa baadhi ya mambo haya.

594
00:25:46,110 --> 00:25:47,850
>> Lakini hebu kwenda nyuma ya lugha.

595
00:25:47,850 --> 00:25:50,499
Kuongelea C #, Python.

596
00:25:50,499 --> 00:25:52,790
Nini kingine inaweza kutumia kwa ajili ya
mtandao programu siku hizi?

597
00:25:52,790 --> 00:25:54,302
Hebu kuzingatia kwamba bado.

598
00:25:54,302 --> 00:25:55,247
>> Watazamaji: PHP.

599
00:25:55,247 --> 00:25:56,080
DAVID J. Malan: PHP.

600
00:25:56,080 --> 00:25:57,413
Na hebu kuja nyuma na kwamba moja.

601
00:25:57,413 --> 00:25:59,310
Hivyo PHP ni kawaida sana kutumika.

602
00:25:59,310 --> 00:26:01,560
PHP huelekea kupata rap mbaya.

603
00:26:01,560 --> 00:26:05,790
Ni ilianza kama lugha kutekelezwa
na folks ambao labda walikuwa si lazima

604
00:26:05,790 --> 00:26:06,960
lugha bora wabunifu.

605
00:26:06,960 --> 00:26:11,290
Na hivyo unaweza kusoma kila aina ya
makala online kuhusu jinsi mbaya PHP ni.

606
00:26:11,290 --> 00:26:13,660
Na kwa bahati mbaya, hii ni
udhihirisho, kwa sehemu,

607
00:26:13,660 --> 00:26:18,727
ya tu mijadala ya kidini
kwamba kuibuka miongoni mwa programmers.

608
00:26:18,727 --> 00:26:20,560
Na hili ni jambo
thamani ya kushika katika akili,

609
00:26:20,560 --> 00:26:24,410
kutokana na mtazamo wa biashara, kwamba
ni rahisi sana kwa watu wa kiufundi

610
00:26:24,410 --> 00:26:26,900
kupata wote kazi juu na wao
maoni juu ya mambo fulani.

611
00:26:26,900 --> 00:26:29,566
Na haimaanishi
kwamba mmoja kunguruma loudest

612
00:26:29,566 --> 00:26:31,870
au na wenye nguvu,
angriest maoni ni haki.

613
00:26:31,870 --> 00:26:34,100
mara nyingi, ni kweli
tu haina jambo.

614
00:26:34,100 --> 00:26:37,970
>> Na hivyo watu wanahoji tu chochote
biases yao wenyewe au kanda faraja ni.

615
00:26:37,970 --> 00:26:40,760
Na hivyo unapaswa kuweka
kuwa katika akili wakati wa kufanya

616
00:26:40,760 --> 00:26:42,622
uamuzi, kwamba tu
kwa sababu mtu anasema

617
00:26:42,622 --> 00:26:45,080
hii ni lugha haki kwa
kazi, hiyo inaweza kuwa ni kweli,

618
00:26:45,080 --> 00:26:48,350
lakini pia tu inaweza kuwa ni
lugha ya kulia ndani ya ujuzi wao wenyewe

619
00:26:48,350 --> 00:26:49,267
kuweka au eneo la faraja.

620
00:26:49,267 --> 00:26:52,600
Ambayo si mbaya, lakini unapaswa kutambua
kwamba huenda kuna baadhi ya mazingira huko.

621
00:26:52,600 --> 00:26:54,440
Kuna baadhi ya objectively
kauli makosa,

622
00:26:54,440 --> 00:26:59,080
kama C ni lugha vibaya kutumia
siku hizi kwa ajili ya utekelezaji tovuti

623
00:26:59,080 --> 00:27:00,520
karibu kila wakati.

624
00:27:00,520 --> 00:27:03,370
Lakini siyo mantiki
kusema kwamba yoyote ya hizi

625
00:27:03,370 --> 00:27:05,700
ni makosa kwamba tumekuwa ikizunguka hivi sasa.

626
00:27:05,700 --> 00:27:08,180
>> PHP aliyepata kupitia matoleo mengi.

627
00:27:08,180 --> 00:27:11,310
Hivyo lugha huwa na kuwa na toleo la
idadi kuhusishwa na wao.

628
00:27:11,310 --> 00:27:15,390
PHP ni hadi, nadhani, toleo 7 sasa,
hivyo imekuwa karibu kwa muda kabisa.

629
00:27:15,390 --> 00:27:18,270
Na kama lugha kupata karibu zaidi,
wao mara nyingi kupata makala mpya.

630
00:27:18,270 --> 00:27:22,510
Lakini una kukumbuka ya hii
kwa sababu kama tovuti yako imekuwa

631
00:27:22,510 --> 00:27:27,539
kutekelezwa katika toleo 7 ya PHP lakini
wewe ni kujaribu kukimbia tovuti yako,

632
00:27:27,539 --> 00:27:29,830
au labda umefanya outsourced
maendeleo ya kanuni yako

633
00:27:29,830 --> 00:27:31,960
kwa mtu mwingine na wanayokutumia
ni wewe au kutuma kwa ninyi

634
00:27:31,960 --> 00:27:33,960
na wanasema, hapa, kuweka
hii kwenye mtandao kompyuta yako,

635
00:27:33,960 --> 00:27:36,610
kama mtandao wako server ni chache
Miaka outdated-- kama ni

636
00:27:36,610 --> 00:27:39,465
server yako mwenyewe au host-- mtandao
huenda ikawa si kweli kuendesha.

637
00:27:39,465 --> 00:27:41,340
Basi hizi ni aina
ya mambo ambayo mtu

638
00:27:41,340 --> 00:27:44,067
mahitaji ya kuwa kukumbuka ya
wakati kuwaendeleza tovuti

639
00:27:44,067 --> 00:27:45,650
au kutekeleza hayo kwa mara ya kwanza.

640
00:27:45,650 --> 00:27:46,900
>> Nilisikia JavaScript mapema.

641
00:27:46,900 --> 00:27:50,570
Hivyo JavaScript ni ya kuvutia
moja kwa kuwa ni kwa ujumla

642
00:27:50,570 --> 00:27:53,030
mteja upande, kama tutaweza kuona
baada ya mapumziko, ambayo

643
00:27:53,030 --> 00:27:55,000
ina maana ni anaendesha katika browser mtumiaji.

644
00:27:55,000 --> 00:27:58,400
Lakini pia unaweza kukimbia
JavaScript siku hizi

645
00:27:58,400 --> 00:28:03,450
kutumia kitu kinachoitwa
Node.js, ambapo Node.js

646
00:28:03,450 --> 00:28:08,000
ni utaratibu wa mbio
JavaScript code server upande,

647
00:28:08,000 --> 00:28:12,430
badala ya kutumia Python, au
PHP, au lugha nyingine kama hizo.

648
00:28:12,430 --> 00:28:17,820
>> JavaScript ni hasa inafaa
kwa ajili ya maombi chat na muda halisi

649
00:28:17,820 --> 00:28:22,050
maombi, ambapo PHP si kubwa
lugha ya kutekeleza kitu

650
00:28:22,050 --> 00:28:25,050
kama server chat, ambapo watumiaji
kukaa kushikamana na hivyo mara kwa mara.

651
00:28:25,050 --> 00:28:28,760
PHP ni zaidi ya ziara me
mara moja, kupata nyuma matokeo,

652
00:28:28,760 --> 00:28:31,790
na kisha click kiungo mwingine baadhi
sekunde au dakika kuanzia sasa.

653
00:28:31,790 --> 00:28:36,020
Wakati Node.js na JavaScript inaweza kuwa
kutumika zaidi kwa ajili ya uhusiano kuendelea.

654
00:28:36,020 --> 00:28:40,840
Lugha nyingine kwamba mtuhumiwa
ni kawaida kutumika kwa ajili ya mambo ya mtandao?

655
00:28:40,840 --> 00:28:42,800
>> Watazamaji: Je, jQuery kuwa mfumo?

656
00:28:42,800 --> 00:28:44,050
>> DAVID J. Malan: Swali zuri.

657
00:28:44,050 --> 00:28:44,700
Wala.

658
00:28:44,700 --> 00:28:51,210
Napenda wito jQuery maktaba, ambapo
tena maktaba ni tu rundo la kificho

659
00:28:51,210 --> 00:28:53,250
kwamba mtu mwingine ana
imeandikwa kwamba kwa ujumla

660
00:28:53,250 --> 00:28:56,390
kutatua baadhi ya matatizo ambayo
hufanya hivyo, hopefully, rahisi

661
00:28:56,390 --> 00:28:57,760
kwa wewe kufanya kazi yako.

662
00:28:57,760 --> 00:29:00,820
Na napenda kufanya mfano mmoja wa
huu katika mazingira ya mtandao.

663
00:29:00,820 --> 00:29:03,910
>> Katika mazingira ya mtandao kuna
lugha hii, JavaScript,

664
00:29:03,910 --> 00:29:06,690
kwamba tutaweza kuona baadaye, ambapo wewe
anaweza kusema kitu kama hii

665
00:29:06,690 --> 00:29:10,060
"Document.getElementByID."

666
00:29:10,060 --> 00:29:11,490
Na nini mimi simu yake jana?

667
00:29:11,490 --> 00:29:16,800
Kwanza, nadhani, ilikuwa ID kipekee Nilitoa
kwa kipengele kwamba inaonekana kama hii.

668
00:29:16,800 --> 00:29:23,110
"P id =" kwanza ">" na kisha tulikuwa
kama "Lorem ipsum," na kadhalika.

669
00:29:23,110 --> 00:29:28,210
Hivyo kama mimi walikuwa kuandika mpango katika
JavaScript kwa namna fulani kuendesha,

670
00:29:28,210 --> 00:29:30,830
mabadiliko kurasa za mtandao kwamba sisi
walikuwa kucheza na jana,

671
00:29:30,830 --> 00:29:33,010
Napenda kutumia hii
yalionyesha mstari wa kanuni

672
00:29:33,010 --> 00:29:38,700
kupata kwamba snippet fulani ya HTML
kutoka ukurasa wangu, kwamba nodi fulani,

673
00:29:38,700 --> 00:29:39,680
kama tutaweza simu yake.

674
00:29:39,680 --> 00:29:44,540
>> Hata hivyo, katika jQuery, badala ya kuandika
hii, ambayo ni mbichi JavaScript code--

675
00:29:44,540 --> 00:29:48,870
tu nje ya boksi, kwamba ni jinsi gani
kuandika it-- ungependa badala tu kusema,

676
00:29:48,870 --> 00:29:50,260
"#first."

677
00:29:50,260 --> 00:29:52,330
Hiyo ni sawa.

678
00:29:52,330 --> 00:29:56,040
Na hivyo msingi tu juu ya hii sana
mfano arcane, nini labda

679
00:29:56,040 --> 00:29:57,870
ni hoja kwa kutumia jQuery?

680
00:29:57,870 --> 00:30:01,390

681
00:30:01,390 --> 00:30:05,111
Kwa nini developer kutumia maktaba kama
jQuery, kwa kuzingatia mfano huu pekee,

682
00:30:05,111 --> 00:30:05,610
labda?

683
00:30:05,610 --> 00:30:06,335
>> Watazamaji: Chini kanuni.

684
00:30:06,335 --> 00:30:06,780
>> DAVID J. Malan: Yeah.

685
00:30:06,780 --> 00:30:07,530
Ni chini kificho.

686
00:30:07,530 --> 00:30:09,070
Ni tu kwa kasi na aina.

687
00:30:09,070 --> 00:30:11,690
kupingana ni
kwamba inaonekana scarier.

688
00:30:11,690 --> 00:30:13,540
Unaweza si kweli kusoma kushoto kwenda kulia.

689
00:30:13,540 --> 00:30:16,730
Kwa kweli, kwa sababu ni zaidi
punctuation sasa badala ya halisi ya maneno,

690
00:30:16,730 --> 00:30:20,950
Siwezi aina ya kudai kuwa
"Document.getElementByID" anapata

691
00:30:20,950 --> 00:30:23,640
kipengele kutoka hati na ID yake.

692
00:30:23,640 --> 00:30:26,750
Mimi kwa kweli wanaweza kutumia hakuna vile
mnemonics kutoka jambo hili hapa.

693
00:30:26,750 --> 00:30:27,680
>> Hivyo ni biashara mbali.

694
00:30:27,680 --> 00:30:30,763
Kuna sophistication kwamba anakuja
mara nyingi kwa kutumia maktaba, hasa

695
00:30:30,763 --> 00:30:31,440
kama jQuery.

696
00:30:31,440 --> 00:30:34,700
Lakini ukweli ni jQuery ina aina
ya kuwa de facto standard,

697
00:30:34,700 --> 00:30:38,110
ili mtu yeyote karibu hizi
siku ambaye anaandika JavaScript kificho

698
00:30:38,110 --> 00:30:41,520
anatumia jQuery au kitu
kama hayo, na tena anaandika

699
00:30:41,520 --> 00:30:45,200
kama maneno verbose kama
hii, kwa sababu tena, ubinadamu

700
00:30:45,200 --> 00:30:47,850
amejifunza, wow, kwamba alikuwa
aina ya amekosa nafasi

701
00:30:47,850 --> 00:30:49,030
kufanya maisha yetu rahisi.

702
00:30:49,030 --> 00:30:51,140
Hivyo binadamu kufanya maisha yao rahisi.

703
00:30:51,140 --> 00:30:53,310
swali zuri.

704
00:30:53,310 --> 00:30:55,870
>> Lugha nyingine ya kuzingatia.

705
00:30:55,870 --> 00:30:58,660
Napenda kusema miongoni mwa huu
orodha Ruby ni maarufu kabisa.

706
00:30:58,660 --> 00:31:01,310
Na hivyo katika dunia ya
Ruby, kuna mfumo

707
00:31:01,310 --> 00:31:03,590
aitwaye reli, ambayo ni maarufu sana.

708
00:31:03,590 --> 00:31:06,880
Hivyo Ruby juu ya reli ni
kawaida kutumika kujieleza.

709
00:31:06,880 --> 00:31:10,330
Pia katika dunia hii, napenda
mduara Java kwa mambo ya mtandao,

710
00:31:10,330 --> 00:31:14,160
ambapo katika dunia ya Java
unaweza kuwa JSP, au Java

711
00:31:14,160 --> 00:31:18,450
Servlets, ambayo ni teknolojia ya kawaida.

712
00:31:18,450 --> 00:31:22,560
Na hii ni tena njia za kutumia
kwamba lugha katika mazingira server.

713
00:31:22,560 --> 00:31:23,520
>> Hivyo hii ina maana gani?

714
00:31:23,520 --> 00:31:25,770
Kama nimepata kimwili
server, wewe ungekuwa literally

715
00:31:25,770 --> 00:31:30,510
download mtandao wa kompyuta programu
na kufunga hiyo kwa namna

716
00:31:30,510 --> 00:31:33,510
kwamba una msaada kwa ajili ya moja ya
mifumo hii, na ambayo

717
00:31:33,510 --> 00:31:37,260
inaweza, kwa upande wake, kutumia moja au
zaidi ya lugha hizi.

718
00:31:37,260 --> 00:31:40,260
Na katika hali halisi, kama ishara kwa ajili ya
kama jeshi mtandao au baadhi ya wingu

719
00:31:40,260 --> 00:31:41,968
Huduma tukazungumza
kuhusu jana, mara nyingi

720
00:31:41,968 --> 00:31:44,885
mambo tu kuja na
Configuration mashine kwa ajili yenu.

721
00:31:44,885 --> 00:31:46,510
Huwezi haja ya kuweka hii up manually.

722
00:31:46,510 --> 00:31:51,040
Lakini kama alivyofanya, hii ni mahali ambapo jukumu
ya msimamizi wa mfumo, hivyo kusema,

723
00:31:51,040 --> 00:31:51,860
linachukua nafasi.

724
00:31:51,860 --> 00:31:54,151
Yeye au angeweza kweli kufanya
aina hii ya mambo kwa ajili yenu,

725
00:31:54,151 --> 00:31:58,510
au kinachojulikana Mama wavuti Kitabu Cha
ingekuwa mara nyingi kufanya hivyo kwa ajili yenu.

726
00:31:58,510 --> 00:31:59,010
Sawa.

727
00:31:59,010 --> 00:32:03,300
Maswali yoyote juu ya baadhi ya haya hapa?

728
00:32:03,300 --> 00:32:06,690
Au fursa yoyote wakati
zote kuuliza kuhusu lugha?

729
00:32:06,690 --> 00:32:09,500
Mfumo?

730
00:32:09,500 --> 00:32:11,530
Kisha napenda kuanzisha
moja tu wengine maktaba

731
00:32:11,530 --> 00:32:13,150
hilo pia ni ya kawaida sana siku hizi.

732
00:32:13,150 --> 00:32:15,340
Orodha hii inaweza kwenda juu infinitely.

733
00:32:15,340 --> 00:32:19,140
>> Na maktaba hii ni aina ya
kuanza kuanguka nje ya neema.

734
00:32:19,140 --> 00:32:19,850
Imekuwa ni karibu.

735
00:32:19,850 --> 00:32:22,040
Ilikuwa umaarufu na
Twitter kwa muda fulani.

736
00:32:22,040 --> 00:32:24,470
Na sasa kura ya Nje,
kura ya watengenezaji matumizi yake.

737
00:32:24,470 --> 00:32:26,629
Lakini mambo mapya ni kuja
nje na kuja pamoja.

738
00:32:26,629 --> 00:32:29,420
Lakini ngoja tu kukupa hisia
ya nini maana ya kutumia maktaba.

739
00:32:29,420 --> 00:32:32,250
Hivyo tena, JavaScript ni
Lugha maarufu sana.

740
00:32:32,250 --> 00:32:35,340
CSS, au kuachia Style Sheets,
kuongelea jana.

741
00:32:35,340 --> 00:32:36,600
Kwamba, pia, ni omnipresent.

742
00:32:36,600 --> 00:32:40,130
Hakuna mtu hufanya ukurasa wa mtandao leo
bila kutumia HTML na CSS minimally.

743
00:32:40,130 --> 00:32:42,510
Lakini ni mara nyingi sio rahisi
kufanya mambo fulani.

744
00:32:42,510 --> 00:32:46,281
>> Na hivyo basi mimi kwenda getbootstrap.com.

745
00:32:46,281 --> 00:32:46,780
Whoops.

746
00:32:46,780 --> 00:32:48,280
Hiyo si jinsi sisi Spell.

747
00:32:48,280 --> 00:32:52,410
Getbootstrap.com, ambayo
ni kwenda uniongoze

748
00:32:52,410 --> 00:32:56,140
kutua ukurasa kwa ajili ya maktaba hii.

749
00:32:56,140 --> 00:32:59,720
Hivyo wao kwa ukarimu kuwaita
wenyewe mfumo, ambayo

750
00:32:59,720 --> 00:33:02,032
ni aina ya aina ya haki,
lakini mimi bado kuita yake

751
00:33:02,032 --> 00:33:03,490
zaidi ya maktaba ya mfumo.

752
00:33:03,490 --> 00:33:05,760
Lakini hizi ni baadhi tu ya arguable semantiki.

753
00:33:05,760 --> 00:33:12,360
Hebu kwenda CSS tab yao na
napenda kwenda kitu kama hiki.

754
00:33:12,360 --> 00:33:15,450
>> Hivyo kukumbuka kile fomu yetu inaonekana
kama jana juu ya Cloud9?

755
00:33:15,450 --> 00:33:16,370
Ilikuwa ni pretty mbaya.

756
00:33:16,370 --> 00:33:17,320
vifungo shule za zamani.

757
00:33:17,320 --> 00:33:20,420
Nadhani button ilikuwa kijivu na
default. Na kila kitu alikuwa kweli

758
00:33:20,420 --> 00:33:22,420
mpangilio kabisa messily.

759
00:33:22,420 --> 00:33:26,940
Hivyo kama unataka mtandao fomu yako kuangalia
kidogo nicer-- napenda kuvuta hapa.

760
00:33:26,940 --> 00:33:30,050
>> Na kwa nicer Mimi kwa kweli tu
maana aesthetics nitpicky sana.

761
00:33:30,050 --> 00:33:35,390
Hivyo taarifa jinsi sanduku email kuna ina
rounded pembe rectangular yake.

762
00:33:35,390 --> 00:33:37,010
Hivyo ni safi kidogo huko.

763
00:33:37,010 --> 00:33:40,770
Taarifa kwamba email neno
ni pale mpaka mimi kuanza kuandika

764
00:33:40,770 --> 00:33:41,797
na kisha huenda zake.

765
00:33:41,797 --> 00:33:43,130
Hivyo hiyo ni nzuri kipengele kidogo.

766
00:33:43,130 --> 00:33:46,046
Angalia jinsi jambo ni aina ya
inang'aa nicely, ambayo baadhi yenu hii

767
00:33:46,046 --> 00:33:49,069
kupata kwa bure kutoka browser yako,
lakini baadhi ya hii pia ni maktaba,

768
00:33:49,069 --> 00:33:51,360
kificho kwamba watu wengine wana
Imeandikwa kwamba kukupa hii.

769
00:33:51,360 --> 00:33:53,480
>> Kitu kama hii
anitiaye password yangu.

770
00:33:53,480 --> 00:33:58,480
button Hii ni kidogo sexier kuliko
default. Sana katika Vogue sasa hivi.

771
00:33:58,480 --> 00:34:03,570
Tangu iOS 7 au hivyo,
dunia imenipatia gorofa sana,

772
00:34:03,570 --> 00:34:09,000
ambapo dunia kabla alikuwa
kura ya vivuli tone, kura

773
00:34:09,000 --> 00:34:11,040
tafakari juu ya icons.

774
00:34:11,040 --> 00:34:14,170
Mengi kama katika dunia ya mavazi,
kuna mwenendo wa mtindo kwamba kuja na kwenda.

775
00:34:14,170 --> 00:34:16,190
Sasa kila kitu ni gorofa kwenye simu yako.

776
00:34:16,190 --> 00:34:19,159
>> Kwa kweli, kifungo juu yako
iPhone ni sasa tu ya bluu viungo.

777
00:34:19,159 --> 00:34:21,000
Kuna si mara nyingi hata mviringo vifungo.

778
00:34:21,000 --> 00:34:22,791
Hivyo haya ni mambo tu
kwamba kwenda ndani na nje

779
00:34:22,791 --> 00:34:26,659
ya Vogue, na hivyo hii ni jinsi ya unavyoweza
kufanya kisasa zaidi kuangalia mtandao fomu.

780
00:34:26,659 --> 00:34:27,159
Vifungo.

781
00:34:27,159 --> 00:34:29,190
Hivyo Bootstrap ina kura ya vifungo pretty.

782
00:34:29,190 --> 00:34:33,639
Hivyo kama unataka vifungo bluu,
kifungo kijani, bluu, machungwa, nyekundu.

783
00:34:33,639 --> 00:34:35,840
Bootstrap inafanya kuwa rahisi
kufanya mambo haya.

784
00:34:35,840 --> 00:34:38,131
Hizi ni aina ya mambo
kwamba unaweza kabisa

785
00:34:38,131 --> 00:34:41,840
wamefanya jana na CSS na kwa
HTML, lakini ni tu maumivu ya shingo.

786
00:34:41,840 --> 00:34:44,840
Na hivyo badala, nini Bootstrap ingekuwa
kuwa na wewe kufanya ni kitu kama hiki.

787
00:34:44,840 --> 00:34:48,960
>> Kama unataka button-- zamu nje hii
ni HTML tag hatukuwa kutumia yesterday--

788
00:34:48,960 --> 00:34:53,070
na wewe unataka kwa kuangalia
kama kifungo hii ya kijani,

789
00:34:53,070 --> 00:34:57,380
wewe literally tu kuwapa darasani,
ambayo sisi alifanya majadiliano juu ya jana,

790
00:34:57,380 --> 00:34:59,710
ya "BTN btn-mafanikio."

791
00:34:59,710 --> 00:35:00,971
>> Kwa nini maneno hayo?

792
00:35:00,971 --> 00:35:03,470
Twitter, waandishi wa Bootstrap,
alikuja na maneno hayo.

793
00:35:03,470 --> 00:35:05,428
Wangeweza kuwa na kuitwa
nao chochote wanachotaka.

794
00:35:05,428 --> 00:35:08,480
Lakini nini ni kupata sasa ni
mtu mwingine katika Twitter, katika kesi hii,

795
00:35:08,480 --> 00:35:12,360
ina figured nje jinsi gani unaweza kufanya
button kuangalia nzuri na safi na kijani.

796
00:35:12,360 --> 00:35:15,580
Wao vifurushi up kwamba utendaji
darasani CSS, inayoitwa "btn"

797
00:35:15,580 --> 00:35:19,790
na "btn-mafanikio," ili kwamba yeyote kati yetu anaweza
sasa matumizi yake bila hata kufikiria juu

798
00:35:19,790 --> 00:35:20,290
yake.

799
00:35:20,290 --> 00:35:22,880
Hivyo wao yanayotumika mbali
dhana ya kifungo kijani

800
00:35:22,880 --> 00:35:25,320
hivyo hatuna huduma ya juu
kutekeleza wenyewe.

801
00:35:25,320 --> 00:35:28,520
Sisi kwa kweli kujikita katika utekelezaji wa
mambo ya riba na sisi.

802
00:35:28,520 --> 00:35:30,902
>> Kama sisi kitabu chini hapa.

803
00:35:30,902 --> 00:35:32,110
ujumbe wa makosa juu ya screen.

804
00:35:32,110 --> 00:35:35,440
Wakati mwingine unataka ujumbe kidogo
kuonekana juu ya browser.

805
00:35:35,440 --> 00:35:39,729
Yeyote kati yetu anaweza kufanya hii pamoja na baadhi ya
juhudi, baada ya somo jana,

806
00:35:39,729 --> 00:35:40,770
lakini kwa nini wewe kujisumbua?

807
00:35:40,770 --> 00:35:42,540
Hiyo ni kama uninteresting
aesthetic undani.

808
00:35:42,540 --> 00:35:44,248
Hebu kusimama juu
mabega ya Bootstrap

809
00:35:44,248 --> 00:35:49,440
na watupe mambo kama haya,
ambapo sisi literally, kupata sanduku nyekundu,

810
00:35:49,440 --> 00:35:53,220
tu kufanya aya
tag na darasa of-- pole.

811
00:35:53,220 --> 00:35:57,307
"Bg-hatari" atatupa
hii sanduku nyekundu badala yake.

812
00:35:57,307 --> 00:35:59,140
Sasa hebu kwenda kwa
mambo ya kuvutia zaidi.

813
00:35:59,140 --> 00:36:02,950
Kama mimi kwenda nyuma juu ya
ukurasa huu na kwenda Components,

814
00:36:02,950 --> 00:36:05,380
sasa dunia anapata kuvutia zaidi.

815
00:36:05,380 --> 00:36:08,826
Kwa mfano, kawaida sana ni
kushuka chini menus kama hii.

816
00:36:08,826 --> 00:36:11,560
Hii itakuwa kabisa
maumivu kutekeleza.

817
00:36:11,560 --> 00:36:13,610
Na haikuwa kwamba kwa muda mrefu
iliyopita kwamba sisi programmers

818
00:36:13,610 --> 00:36:16,490
ingekuwa kutekeleza haya
aina ya menus kutoka mwanzo.

819
00:36:16,490 --> 00:36:20,800
>> Lakini ni kama dhana ya kawaida
kwamba maktaba kama Bootstrap

820
00:36:20,800 --> 00:36:25,230
kukupa tu uwezo wa kufanya
kushuka chini orodha mbali, mbali kwa urahisi zaidi.

821
00:36:25,230 --> 00:36:27,850
Hakuna njia moja ya kufanya hivyo,
lakini kama mimi kusoma nyaraka

822
00:36:27,850 --> 00:36:32,100
Napenda kuona kwamba, OK, mimi lazima kutumia
HTML hii kama nataka kushuka chini menu

823
00:36:32,100 --> 00:36:34,030
kwamba kutenda kama hiyo.

824
00:36:34,030 --> 00:36:36,690
>> Vile vile, hebu kwenda kifungo kushuka chini.

825
00:36:36,690 --> 00:36:38,470
Hivyo hii ni hata fancier.

826
00:36:38,470 --> 00:36:41,800
Kama mimi nataka hii kwa kuangalia kama kifungo
lakini hiyo pembetatu kidogo maana

827
00:36:41,800 --> 00:36:44,080
Mimi lazima bonyeza juu yake
na kupata orodha hii, hii

828
00:36:44,080 --> 00:36:45,760
ni kwa kutumia lugha inayoitwa JavaScript.

829
00:36:45,760 --> 00:36:47,470
Na tunaweza zote kutekeleza
huu katika JavaScript.

830
00:36:47,470 --> 00:36:49,720
Lakini tena, hii ni gurudumu
wewe hawataki na kuibuka.

831
00:36:49,720 --> 00:36:52,700
Unataka tu kuchukua ni mbali
maktaba rafu kwa hili.

832
00:36:52,700 --> 00:36:58,145
>> Hebu kwenda kwa kitu
kama maendeleo baa.

833
00:36:58,145 --> 00:36:59,770
Hivyo kitu kama hii ni aina ya baridi.

834
00:36:59,770 --> 00:37:02,910
Kama wameweza milele kuonekana maendeleo
bar kusonga katika screen,

835
00:37:02,910 --> 00:37:06,380
utekelezaji wa ambayo mara nyingi
ni tu icon inazunguka.

836
00:37:06,380 --> 00:37:10,200
Kwa kweli, tu kama kando, basi
mimi kwenda Ajax-- ni nini?

837
00:37:10,200 --> 00:37:10,710
Ajax info?

838
00:37:10,710 --> 00:37:11,720
Whoops.

839
00:37:11,720 --> 00:37:13,035
Ajaxinfo.

840
00:37:13,035 --> 00:37:14,800
Hebu kumbuka mahali.

841
00:37:14,800 --> 00:37:15,820
Kuna sisi kwenda.

842
00:37:15,820 --> 00:37:19,850
>> Hivyo kama wameweza milele kuonekana baadhi uhuishaji
wakati ukurasa ni upakiaji, au kufikiri,

843
00:37:19,850 --> 00:37:25,410
au kuokoa, au kujenga kitu,
wanaweza kuona michoro kama hawa.

844
00:37:25,410 --> 00:37:28,800
Hivyo hebu tuangalie kitu
kama hii moja hapa,

845
00:37:28,800 --> 00:37:33,550
na hebu kuchagua rangi foreground ya
kijani, ambayo anahisi aina ya kirafiki.

846
00:37:33,550 --> 00:37:34,545
Naweza bonyeza hii?

847
00:37:34,545 --> 00:37:35,500
Kuja moja.

848
00:37:35,500 --> 00:37:36,000
SAWA.

849
00:37:36,000 --> 00:37:38,930
Tutaweza tu kwenda na nyekundu kwa sababu
kwamba ni nini sisi ni kupata.

850
00:37:38,930 --> 00:37:40,250
Hivyo hapa sisi kuwa nayo.

851
00:37:40,250 --> 00:37:43,940
>> Hivyo kama wameweza milele kuonekana hii juu ya screen,
ambapo ghafla inaonekana na kisha

852
00:37:43,940 --> 00:37:47,550
ghafla kutoweka, ni nini
ni hiyo kutekeleza hayo?

853
00:37:47,550 --> 00:37:48,970
Naam, hii ni tu GIF.

854
00:37:48,970 --> 00:37:52,850
G-I-F. Na hii ni animated
faili, ambayo ina maana tu

855
00:37:52,850 --> 00:37:54,327
ni kama umri wa shule Comic kitabu.

856
00:37:54,327 --> 00:37:57,160
Kuna tu rundo la tofauti
muafaka kwamba ni kwenda [kigugumizi]

857
00:37:57,160 --> 00:37:58,085
na kurudia tu.

858
00:37:58,085 --> 00:38:00,090
Na ni kujenga
udanganyifu wa harakati.

859
00:38:00,090 --> 00:38:03,070
>> Hivyo kwa haraka kama ukurasa inafanywa
upakiaji au kufanya kitu,

860
00:38:03,070 --> 00:38:04,610
nini programu nini?

861
00:38:04,610 --> 00:38:07,500
Naam, yeye au yeye tu ngozi picha hii.

862
00:38:07,500 --> 00:38:11,536
Basi wote maendeleo bar ni ni aina
ya kama movie wewe ni kuangalia.

863
00:38:11,536 --> 00:38:14,660
Wewe ni aina ya oblivious na ukweli
kwamba siyo kweli kufanya kitu chochote,

864
00:38:14,660 --> 00:38:15,940
ni kusonga tu.

865
00:38:15,940 --> 00:38:19,150
>> Na kisha, wakati ni kosa inaendelea,
wao tu kujificha au kugeuka kuwa mbali.

866
00:38:19,150 --> 00:38:21,115
Na kwamba ni uchawi wote
kwamba kinaendelea huko.

867
00:38:21,115 --> 00:38:22,770
Bootstrap inakupa
kitu kidogo fancier,

868
00:38:22,770 --> 00:38:25,030
ambapo unaweza kweli
kuona asilimia kama unaendelea,

869
00:38:25,030 --> 00:38:27,840
lakini pia ni aina
ya uhuishaji rahisi.

870
00:38:27,840 --> 00:38:32,250
>> Hebu tuangalie baadhi ya mwisho
mifano zaidi tata hapa.

871
00:38:32,250 --> 00:38:35,526
Kitu kama modal.

872
00:38:35,526 --> 00:38:36,900
Je, mtu yeyote kujua nini modal ni?

873
00:38:36,900 --> 00:38:39,880

874
00:38:39,880 --> 00:38:42,550
modal dirisha kwa ujumla ni
moja kwamba zinatakiwa

875
00:38:42,550 --> 00:38:46,880
kuchukua udhibiti wa foreground na
kuzuia kutoka kwa kufanya kitu kingine chochote.

876
00:38:46,880 --> 00:38:50,290
Ni aina ya vikosi mtumiaji
kipaumbele kwa katikati ya screen,

877
00:38:50,290 --> 00:38:52,290
kuifungia yao nje, kwa kawaida,
ya kila kitu kingine.

878
00:38:52,290 --> 00:38:55,830
>> Hivyo kama mimi kuzindua demo hii,
screen mapenzi kwa ujumla kuwa kijivu.

879
00:38:55,830 --> 00:38:57,060
Naam, ni jinsi gani sisi kufanya hivyo kijivu?

880
00:38:57,060 --> 00:38:59,080
Naam, sisi pengine tu
kubadilishwa rangi ya asili

881
00:38:59,080 --> 00:39:01,060
kama tulivyofanya jana
au kitu kama hicho.

882
00:39:01,060 --> 00:39:03,490
Labda ni overlay
kwamba nusu ya uwazi.

883
00:39:03,490 --> 00:39:06,320
Na sasa taarifa unaweza kufanya
mambo dhana kama hii.

884
00:39:06,320 --> 00:39:09,930
Hivyo kama wewe milele bonyeza kifungo
na wanataka kidogo pop nje kuonekana,

885
00:39:09,930 --> 00:39:10,710
unaweza kufanya hivyo.

886
00:39:10,710 --> 00:39:12,340
Na hivyo anayenijali all-- yeah?

887
00:39:12,340 --> 00:39:15,791
>> Watazamaji: Hivyo kwa Bootstrap,
kupata kuingizwa,

888
00:39:15,791 --> 00:39:21,002
Ni rahisi kama kama jana
tulivyofanya CSS mitindo ukurasa?

889
00:39:21,002 --> 00:39:21,960
DAVID J. Malan: Kwa hakika.

890
00:39:21,960 --> 00:39:22,835
swali zuri.

891
00:39:22,835 --> 00:39:24,480
Hebu kwenda Anza.

892
00:39:24,480 --> 00:39:26,090
Na ndiyo.

893
00:39:26,090 --> 00:39:30,920
Wote una kufanya ili
matumizi Bootstrap kimsingi ni nakala

894
00:39:30,920 --> 00:39:35,910
na kuweka hizi mistari mitatu ndefu ya
kificho katika juu ya mtandao yako mwenyewe page--

895
00:39:35,910 --> 00:39:38,892
mkuu wa page-- yako
na uko juu na kukimbia.

896
00:39:38,892 --> 00:39:41,850
Na kuna njia tofauti za kufanya
yake, lakini hii itakuwa rahisi.

897
00:39:41,850 --> 00:39:45,190
>> Basi nini kusaidia kuhusu haya yote?

898
00:39:45,190 --> 00:39:47,524
Naam, kama wewe si sana
Utekelezaji wa tovuti

899
00:39:47,524 --> 00:39:50,106
lakini wewe ni kujaribu kubuni,
au unataka kutoa mtu

900
00:39:50,106 --> 00:39:53,220
na waya sura michoro, hivyo kusema,
au renditions tu msanii wa nini

901
00:39:53,220 --> 00:39:56,080
unataka kufanya, mimi, na hii
siku, mara nyingi kwenda kwenye tovuti

902
00:39:56,080 --> 00:39:58,660
kama Bootstrap, ambapo kama mimi
unataka kutekeleza something--

903
00:39:58,660 --> 00:40:02,290
kama hivi karibuni juu ya chuo
tulitaka kutekeleza

904
00:40:02,290 --> 00:40:06,170
mtandao msingi chombo kwa punde
Bila shaka Harvard ya catalog,

905
00:40:06,170 --> 00:40:08,770
na kuifanya rahisi kwa wanafunzi
kuvinjari kwa njia ya kozi

906
00:40:08,770 --> 00:40:10,930
na kuongeza kozi ya
orodha ya ununuzi, hivyo kusema,

907
00:40:10,930 --> 00:40:13,070
aina ya kuamua nini
walitaka kuchukua.

908
00:40:13,070 --> 00:40:16,252
>> Mimi alikuwa anajaribu kufikiria kwa
mwenyewe, nini viungo ingekuwa

909
00:40:16,252 --> 00:40:17,460
tunataka kutumia ili kujenga hii?

910
00:40:17,460 --> 00:40:19,050
Kitu gani user interface kuwa kama?

911
00:40:19,050 --> 00:40:22,800
Na tu kuangalia kwa kupitia tovuti kama
huu au nyingine kama maeneo ya maktaba,

912
00:40:22,800 --> 00:40:26,560
unaweza kupata uongozi, kwa sababu wow,
Naweza kutumia widget hii, na widget hii,

913
00:40:26,560 --> 00:40:27,330
na widget hii.

914
00:40:27,330 --> 00:40:29,080
Na kisha kweli nini
programu kuanza

915
00:40:29,080 --> 00:40:32,800
kufanya, hasa katika siku hizi katika hii
zaidi ya kisasa ulimwengu wa programu ya mtandao,

916
00:40:32,800 --> 00:40:35,827
ni programu inazidi
kuhusu wiring mambo pamoja.

917
00:40:35,827 --> 00:40:38,910
Aina ya kuchukua hii mbali rafu,
hii mbali rafu, hii mbali rafu,

918
00:40:38,910 --> 00:40:41,954
na wewe kuwa smart moja
kuungana wote wa dots hizo,

919
00:40:41,954 --> 00:40:45,120
lakini hatimaye kujenga kitu na tena
amesimama juu ya mabega ya wengine,

920
00:40:45,120 --> 00:40:49,370
hivyo kwamba huna kutumia mwezi
utekelezaji wa kijinga kushuka chini orodha,

921
00:40:49,370 --> 00:40:52,080
ambayo ni kweli vigumu kufanya kama
unataka kufanya kazi ya Chrome,

922
00:40:52,080 --> 00:40:55,220
na IE, Firefox, na yoyote
idadi ya browsers nyingine.

923
00:40:55,220 --> 00:40:59,060
Hii ni kwa nini kuna hii tajiri
programu ya kibiashara na ya chanzo

924
00:40:59,060 --> 00:41:01,220
sekta kama vile.

925
00:41:01,220 --> 00:41:06,810
>> Watazamaji: Hivyo haina Bootstrap kupata updated
na una kisha update viungo yako?

926
00:41:06,810 --> 00:41:07,820
>> DAVID J. Malan: Ni anafanya.

927
00:41:07,820 --> 00:41:09,090
Naam, ndiyo, ni gani.

928
00:41:09,090 --> 00:41:12,540
Bootstrap sasa katika toleo 3.3.6.

929
00:41:12,540 --> 00:41:16,720
Na kwa ujumla nini ungependa do--
hii ni kweli kutaja thamani.

930
00:41:16,720 --> 00:41:19,200
Kuna nini kwa ujumla
inayojulikana kama versioning semantic

931
00:41:19,200 --> 00:41:20,160
mfumo katika dunia.

932
00:41:20,160 --> 00:41:21,320
Si kila mtu gani hii.

933
00:41:21,320 --> 00:41:26,410
>> Lakini kama wameweza kuonekana idadi version
ambayo ni ya aina x.y.z--

934
00:41:26,410 --> 00:41:30,240
hivyo kwa mfano, toleo la kwanza
ya mpango inaweza kuwa 1.0.0.

935
00:41:30,240 --> 00:41:34,970
Au kama ni sana, sana beta, au
hata alpha hadhi, ambayo ina maana ya matumizi

936
00:41:34,970 --> 00:41:37,620
katika hatari yako mwenyewe, siyo
kweli tayari kwa wakati mkuu,

937
00:41:37,620 --> 00:41:42,080
unaweza hata kuanza 0.0.1
au baadhi ya vile wajibu.

938
00:41:42,080 --> 00:41:47,260
Lakini kama programu kuanza saa version
1.0, au equivalently 1.0.0,

939
00:41:47,260 --> 00:41:50,530
kawaida, nini ya kawaida hizi
days-- ingawa si omnipresent-- ni

940
00:41:50,530 --> 00:41:53,520
kama kampuni au
mtu binafsi fixes programu

941
00:41:53,520 --> 00:41:56,140
baadhi mdudu katika baadhi ya kipande
cha programu kwamba kweli

942
00:41:56,140 --> 00:42:01,620
Ilikuwa mdudu, ambaye marekebisho haipaswi
athari wewe katika all-- haina mabadiliko

943
00:42:01,620 --> 00:42:03,940
tabia programu hiyo,
ni tu kunasa kitu

944
00:42:03,940 --> 00:42:06,580
kwamba haikuwa kazi
properly-- wewe ungekuwa kawaida

945
00:42:06,580 --> 00:42:08,890
update thamani z huko.

946
00:42:08,890 --> 00:42:12,900
Ambayo ina maana mtu kama Kareem
inaweza tu kwenda katika tovuti yake,

947
00:42:12,900 --> 00:42:19,470
upofu mabadiliko ya idadi version
kutoka 1.0.0 kwa 1.0.1, ila ni, meli hiyo,

948
00:42:19,470 --> 00:42:21,880
na katika nadharia, sio kuwa na
wasiwasi kwamba yeye kuvunjwa tu

949
00:42:21,880 --> 00:42:24,430
tovuti yake kwa sababu ya
baadhi ukosefu wa utendaji,

950
00:42:24,430 --> 00:42:25,870
kwa sababu kitu kingine kukatika.

951
00:42:25,870 --> 00:42:28,740
>> Wakati huo huo, kama mimi
programu au baadhi ya kampuni

952
00:42:28,740 --> 00:42:35,500
walikuwa na kufanya baadhi ya muhimu
mabadiliko ambayo anaongeza utendaji,

953
00:42:35,500 --> 00:42:40,320
Nipate update sisi
1.1.0 kwa sababu mimi nina kweli

954
00:42:40,320 --> 00:42:42,200
kubadili tabia ya maktaba.

955
00:42:42,200 --> 00:42:44,470
Mimi nina kutoa utendaji labda zaidi.

956
00:42:44,470 --> 00:42:48,490
Hatimaye, kama ningekuwa kweli
mabadiliko ya kimsingi programu hivyo

957
00:42:48,490 --> 00:42:54,380
kiasi kwamba itakuwa mapumziko wengi
watumiaji tovuti au maombi,

958
00:42:54,380 --> 00:42:59,550
basi mimi nina wajibu, katika mtindo huu, kwa
kuboresha idadi kubwa toleo pia,

959
00:42:59,550 --> 00:43:01,059
ambayo ni ya mabadiliko ya kuvunja.

960
00:43:01,059 --> 00:43:03,725
Kwa maneno mengine, nipate kuwa
imekoma msaada kwa wale tone

961
00:43:03,725 --> 00:43:04,350
down menu.

962
00:43:04,350 --> 00:43:07,790
Hivyo kama wewe kuboresha na 2.0, nusu
tovuti yako inaweza kuacha kufanya kazi.

963
00:43:07,790 --> 00:43:10,950
Na hii ni aina ya ishara
kwa jamii kwa nini

964
00:43:10,950 --> 00:43:13,223
kushiriki katika kufanya kuboresha.

965
00:43:13,223 --> 00:43:16,710

966
00:43:16,710 --> 00:43:18,020
fursa nzuri ya kuongeza.

967
00:43:18,020 --> 00:43:18,718
Maswali mengine?

968
00:43:18,718 --> 00:43:21,761

969
00:43:21,761 --> 00:43:22,260
Sawa.

970
00:43:22,260 --> 00:43:26,945
Naam hebu tuangalie mwisho moja
mada katika sehemu hii ya programu

971
00:43:26,945 --> 00:43:30,640
ya teknolojia mwingi,
ambazo ni kuhusiana na mkononi.

972
00:43:30,640 --> 00:43:36,232
>> Hivyo katika dunia ya simu za mkononi leo
wewe have-- na iPads, na nyuso,

973
00:43:36,232 --> 00:43:37,940
na aina wale wote
ya devices-- una

974
00:43:37,940 --> 00:43:40,950
mengi ya uchaguzi wakati
suala la utekelezaji wa

975
00:43:40,950 --> 00:43:47,270
maombi au tovuti kwa
vifaa ya wateja wako mkononi.

976
00:43:47,270 --> 00:43:51,570
Hivyo tu kueleza
dhahiri, labda siku hizi,

977
00:43:51,570 --> 00:43:54,960
kile ni majukwaa ya
kuendeleza kwa katika nafasi ya simu?

978
00:43:54,960 --> 00:43:59,650
Nini vifaa inaweza unataka
kusaidia na programu yako au tovuti?

979
00:43:59,650 --> 00:44:00,317
>> Watazamaji: Apple.

980
00:44:00,317 --> 00:44:01,108
DAVID J. Malan: Sawa.

981
00:44:01,108 --> 00:44:01,820
Hivyo vifaa Apple.

982
00:44:01,820 --> 00:44:06,740
Hivyo kwamba maana iPhone, na kwamba
ina maana iPad, na labda hata iPod.

983
00:44:06,740 --> 00:44:07,627
Kipi kingine?

984
00:44:07,627 --> 00:44:11,006

985
00:44:11,006 --> 00:44:11,505
Olivier?

986
00:44:11,505 --> 00:44:11,970
>> Watazamaji: Android.

987
00:44:11,970 --> 00:44:13,111
>> DAVID J. Malan: Android.

988
00:44:13,111 --> 00:44:13,610
SAWA.

989
00:44:13,610 --> 00:44:17,335
simu Hivyo Android, Android
vidonge, Android soko

990
00:44:17,335 --> 00:44:21,240
ni hata messier because-- na
hata Apple ni kuwa na messy.

991
00:44:21,240 --> 00:44:23,960
Wakati mara moja juu ya muda
iPhone alikuwa ukubwa fulani,

992
00:44:23,960 --> 00:44:26,560
na kutumika mara ukubwa fulani,
na iPod alikuwa ukubwa fulani, sasa

993
00:44:26,560 --> 00:44:33,420
tuna kutumika Minis, na nyembamba
ndio, na iPhone 6 Plus na 6.

994
00:44:33,420 --> 00:44:34,407
Ni kuwa fujo.

995
00:44:34,407 --> 00:44:35,740
Ni kuwa Android dunia.

996
00:44:35,740 --> 00:44:39,030
>> Na mimi kusema hii na aina ya rolling
macho yangu kwa sababu kutoka developer ya

997
00:44:39,030 --> 00:44:41,680
mtazamo, ni
maumivu ya shingo wakati

998
00:44:41,680 --> 00:44:45,686
huna Steve Jobs '
maono ya udhibiti kamili

999
00:44:45,686 --> 00:44:47,060
juu ya yote ya specifikationer haya.

1000
00:44:47,060 --> 00:44:49,726
Apple bado anafanya kwa sababu wao uko
ndio ujenzi wa vifaa.

1001
00:44:49,726 --> 00:44:52,690
Lakini ni kitu kizuri, kama
Mimi nina programu developer,

1002
00:44:52,690 --> 00:44:54,520
kujua tu kwamba yangu
iPhone ni daima kwenda

1003
00:44:54,520 --> 00:44:56,850
kuwa hii kubwa kwa sababu
hiyo ina maana mimi daima kujua

1004
00:44:56,850 --> 00:44:58,847
kiasi gani screen mali isiyohamishika nina.

1005
00:44:58,847 --> 00:45:01,180
Hivyo kama nataka kuweka icon
katika kona ya juu upande wa kushoto,

1006
00:45:01,180 --> 00:45:04,530
ni kwenda kuwa katika exact
mahali kwenye kifaa kila mteja moja ya.

1007
00:45:04,530 --> 00:45:07,140
>> Lakini katika ulimwengu wa iPhone
6s na iPhone 6 Pluses

1008
00:45:07,140 --> 00:45:10,570
na katika ulimwengu wa Android
simu, ni wote juu ya ramani.

1009
00:45:10,570 --> 00:45:13,580
Na hivyo kufanya kuwa vigumu kwa mpango
mambo, hasa user interfaces,

1010
00:45:13,580 --> 00:45:18,270
kwa sababu sasa una kuanza kupanga
user interfaces yako kiasi, si

1011
00:45:18,270 --> 00:45:19,730
kabisa.

1012
00:45:19,730 --> 00:45:23,524
Na huo imekuwa kweli juu ya browsers,
na kopyuta, na Laptops kwa miaka

1013
00:45:23,524 --> 00:45:25,690
kwa sababu wewe, bila shaka,
kuwa na ukubwa tofauti screen.

1014
00:45:25,690 --> 00:45:26,189
>> Kipi kingine?

1015
00:45:26,189 --> 00:45:30,170
Unaweza kuwa na nyuso,
kama kutoka Microsoft.

1016
00:45:30,170 --> 00:45:31,270
Unaweza have--

1017
00:45:31,270 --> 00:45:32,270
Watazamaji: Windows simu.

1018
00:45:32,270 --> 00:45:32,816
DAVID J. Malan: Nini hiyo?

1019
00:45:32,816 --> 00:45:33,570
Watazamaji: Windows simu.

1020
00:45:33,570 --> 00:45:34,403
DAVID J. Malan: Ndiyo.

1021
00:45:34,403 --> 00:45:37,570
Hivyo simu madirisha bado inaweza kupatikana.

1022
00:45:37,570 --> 00:45:41,840
Aina ya aina ya BlackBerry za,
lakini wao kuendelea kujaribu.

1023
00:45:41,840 --> 00:45:43,900
Na kisha mashada ya vifaa vingine.

1024
00:45:43,900 --> 00:45:48,020
Hivyo kwa sehemu kubwa, hebu
kusema hawa ndio

1025
00:45:48,020 --> 00:45:49,520
huduma ya juu kwa sasa.

1026
00:45:49,520 --> 00:45:51,890
Hakika Apple stuff,
hakika Android stuff,

1027
00:45:51,890 --> 00:45:55,640
na miongoni mwa Windows, kama vidonge uso
wanaonekana kuwa kuambukizwa juu pretty vizuri.

1028
00:45:55,640 --> 00:45:58,030
>> Na hivyo miongoni mwa wale vifaa,
kama unataka unaendelea nje,

1029
00:45:58,030 --> 00:46:02,677
hebu sema, uwepo mkononi kwa ajili yako
kampuni, ni aina gani ya kubuni maamuzi

1030
00:46:02,677 --> 00:46:03,510
je, una kufanya?

1031
00:46:03,510 --> 00:46:06,350
Naam, sisi tayari alisema
katika dunia Apple,

1032
00:46:06,350 --> 00:46:08,790
kuna angalau lugha mbili
kwamba ni kawaida kutumika.

1033
00:46:08,790 --> 00:46:10,260
Moja aliitwa nini?

1034
00:46:10,260 --> 00:46:11,260
>> Watazamaji: Lengo-C.

1035
00:46:11,260 --> 00:46:11,560
>> DAVID J. Malan: Yeah.

1036
00:46:11,560 --> 00:46:13,600
Hivyo Lengo-C, ambayo ni mkubwa.

1037
00:46:13,600 --> 00:46:17,720
Ni pia lugha kwamba wengi Mac
maombi bado yaliyoandikwa katika.

1038
00:46:17,720 --> 00:46:18,964
Kisha wengine wapya mmoja alikuwa?

1039
00:46:18,964 --> 00:46:19,630
Watazamaji: Swift.

1040
00:46:19,630 --> 00:46:20,590
DAVID J. Malan: Swift.

1041
00:46:20,590 --> 00:46:23,900
Na wale ni aina ya
mbili kujua kumvutia folks.

1042
00:46:23,900 --> 00:46:28,238
Kisha katika dunia Android,
nini lugha haina Android kutumia?

1043
00:46:28,238 --> 00:46:30,618
>> Watazamaji: C #?

1044
00:46:30,618 --> 00:46:31,570
>> Watazamaji: Java.

1045
00:46:31,570 --> 00:46:34,230
>> DAVID J. Malan: Java ni
lugha ya "du jour."

1046
00:46:34,230 --> 00:46:37,950
Katika dunia Windows, hakika,
tutaweza kusema C # katika kesi hiyo.

1047
00:46:37,950 --> 00:46:40,590
Hivyo tayari hii ni aina ya
annoying, kwa sababu nini

1048
00:46:40,590 --> 00:46:43,070
takeaway kwa ajili ya biashara
mmiliki au mtu ambaye tu

1049
00:46:43,070 --> 00:46:44,570
anataka unaendelea nje mbele ya mkononi?

1050
00:46:44,570 --> 00:46:45,220
Kama, damn it?

1051
00:46:45,220 --> 00:46:48,590
Kama, kama mimi wanataka kusaidia
haki pana msingi user,

1052
00:46:48,590 --> 00:46:52,180
Nina kuandika, inaweza kuonekana,
tofauti maombi matatu.

1053
00:46:52,180 --> 00:46:55,630
Moja katika moja ya lugha hizi,
moja katika Java, moja katika C #.

1054
00:46:55,630 --> 00:46:59,620
Na hata kama nataka utendaji
kuwa kufanana, haijalishi.

1055
00:46:59,620 --> 00:47:02,940
Mimi bado haja ya kutumia tofauti
Lugha kwa sababu Apple, na Microsoft,

1056
00:47:02,940 --> 00:47:06,084
na Google msaada wote
mazingira tofauti.

1057
00:47:06,084 --> 00:47:07,750
Na hii imekuwa ni changamoto kwa miaka.

1058
00:47:07,750 --> 00:47:10,100
Nyuma katika siku, wakati
watu kutumika kununua programu

1059
00:47:10,100 --> 00:47:12,230
katika kompyuta kuhifadhi katika
kuogopa masanduku amefungwa,

1060
00:47:12,230 --> 00:47:14,470
ungependa ama kuwa na
kufikia kwa ajili ya rafu Mac,

1061
00:47:14,470 --> 00:47:19,040
au for-- labda hii Mac ndogo sana
shelf-- au kubwa Windows rafu

1062
00:47:19,040 --> 00:47:19,980
na kununua baadhi ya programu.

1063
00:47:19,980 --> 00:47:22,813
Na mara nyingi sana, hapakuwa na hata
chochote kwa ajili yenu juu ya rafu Mac.

1064
00:47:22,813 --> 00:47:23,430
Kwa nini?

1065
00:47:23,430 --> 00:47:26,900
Naam, makampuni aliamua kama 90%
ya dunia, 95% ya dunia

1066
00:47:26,900 --> 00:47:31,180
ina PC, kwa nini kujisumbua hata
utekelezaji wa mambo juu ya Mac OS?

1067
00:47:31,180 --> 00:47:34,370
>> Kama aside-- jumla
digression-- kwa nini ni

1068
00:47:34,370 --> 00:47:40,960
kwamba Mac inaonekana hivyo huweza kuingia kwenye virusi,
na minyoo, na vitisho vya usalama?

1069
00:47:40,960 --> 00:47:44,040
Ni Apple bora wakati huu?

1070
00:47:44,040 --> 00:47:45,934
Bora katika kutunza kompyuta salama?

1071
00:47:45,934 --> 00:47:47,750
>> Watazamaji: Ndogo watazamaji?

1072
00:47:47,750 --> 00:47:50,720
>> DAVID J. Malan: Hiyo ni
pengine kidogo kubwa na hiyo.

1073
00:47:50,720 --> 00:47:54,740
Hivyo watumiaji wengi wa Macs na
muda mrefu wamedai, loo, kutumia Mac,

1074
00:47:54,740 --> 00:47:57,630
wewe utakuwa na kinga ya virusi, na
minyoo, na mambo yote haya

1075
00:47:57,630 --> 00:47:59,180
kwamba kwa muda mrefu kusumbuliwa PC.

1076
00:47:59,180 --> 00:48:02,050
Hiyo inaweza kuwa ni kwa sababu Apple
ina programmers bora

1077
00:48:02,050 --> 00:48:05,250
na wao kuandika programu bora au
mfumo wa uendeshaji ilikuwa bora iliyoundwa.

1078
00:48:05,250 --> 00:48:06,870
Labda, lakini pengine si.

1079
00:48:06,870 --> 00:48:10,840
>> Ni pengine kuwa wakati uko
12 mwenye umri wa miaka, au 30 kitu

1080
00:48:10,840 --> 00:48:13,510
aina ya wamekaa kwenye uandishi wa nyumbani
programu hatarishi kuchukua juu ya

1081
00:48:13,510 --> 00:48:17,480
dunia, wewe ni kwenda baada ya
Lengo kubwa watazamaji.

1082
00:48:17,480 --> 00:48:20,590
95% ya dunia ambaye anaweza
kuwa mbio Windows au baadhi

1083
00:48:20,590 --> 00:48:21,740
variants yake.

1084
00:48:21,740 --> 00:48:23,800
Hivyo kuna kidogo pande zote mbili.

1085
00:48:23,800 --> 00:48:25,710
Lakini kwa mikopo yao,
Apple, kwa ufahamu wangu,

1086
00:48:25,710 --> 00:48:28,270
ina si kweli ulitarajiwa wenyewe
kama kuwa salama zaidi,

1087
00:48:28,270 --> 00:48:32,110
tangu wewe ni kuwakaribisha tu mchezo wa kuigiza kama
wewe kufanya madai kwamba, napenda kufikiri.

1088
00:48:32,110 --> 00:48:32,610
>> Sawa.

1089
00:48:32,610 --> 00:48:36,490
Bila kupata mbali sana chini
kwamba, jinsi gani sisi kutatua hili?

1090
00:48:36,490 --> 00:48:39,670
Je, una kununua au kufanya una
kulipa watu watatu tofauti kuendeleza

1091
00:48:39,670 --> 00:48:41,540
programu yako?

1092
00:48:41,540 --> 00:48:42,870
Je, kuchukua moja juu ya nyingine?

1093
00:48:42,870 --> 00:48:45,460
Kile lazima kuongoza yako
kufikiri hapa unafikiri?

1094
00:48:45,460 --> 00:48:47,960

1095
00:48:47,960 --> 00:48:48,460
Kareem?

1096
00:48:48,460 --> 00:48:51,001

1097
00:48:51,001 --> 00:48:51,500
Nope.

1098
00:48:51,500 --> 00:48:54,190
Mtu mwingine.

1099
00:48:54,190 --> 00:48:56,885
>> Watazamaji: Tu kuja na vifaa.

1100
00:48:56,885 --> 00:48:58,510
DAVID J. Malan: Fuatana vifaa?

1101
00:48:58,510 --> 00:48:59,533
Unamaanisha nini?

1102
00:48:59,533 --> 00:49:01,282
>> Watazamaji: Kwa
mazingira. [Inaudible]

1103
00:49:01,282 --> 00:49:04,867

1104
00:49:04,867 --> 00:49:06,200
DAVID J. Malan: Hivyo kwamba ni kweli.

1105
00:49:06,200 --> 00:49:09,280
Lakini wateja wako,
wakati huo huo, inaweza kuwa iphone,

1106
00:49:09,280 --> 00:49:13,530
wapate kuwa simu za Android, wao
anaweza kuwa vidonge yaliyotolewa na Microsoft.

1107
00:49:13,530 --> 00:49:19,040
Hivyo ni jinsi gani una mkakati mkononi
kwa wote wa watumiaji hawa tofauti?

1108
00:49:19,040 --> 00:49:23,320
Ni kuonekana kuwa kama ni gharama,
hebu sema $ 1,000 kwa kufanya iPhone

1109
00:49:23,320 --> 00:49:25,940
maombi, ni kwenda
kwa gharama wewe $ 2,000 hadi kufanya

1110
00:49:25,940 --> 00:49:29,250
iPhone maombi na an
Android maombi, au $ 3,000

1111
00:49:29,250 --> 00:49:31,407
pia kusaidia vifaa Windows vilevile.

1112
00:49:31,407 --> 00:49:33,990
Kwamba pengine kabisa
understatement, na ni nguvu hata

1113
00:49:33,990 --> 00:49:36,050
kuwa na uhusiano linear kama hiyo.

1114
00:49:36,050 --> 00:49:41,065
>> Watazamaji: Kama unataka kuwa na programu au
siyo, unaweza kuwa na tovuti msikivu.

1115
00:49:41,065 --> 00:49:41,940
DAVID J. Malan: Good.

1116
00:49:41,940 --> 00:49:46,255
Watazamaji: Au unaweza kuwa na programu ya asili.

1117
00:49:46,255 --> 00:49:47,130
DAVID J. Malan: Yeah.

1118
00:49:47,130 --> 00:49:50,260
Hivyo kwa mantiki hii yote hapa,
tumekuwa kuzungumza kuhusu nini

1119
00:49:50,260 --> 00:49:53,190
watu kuita maombi ya asili.

1120
00:49:53,190 --> 00:49:58,040
Hiyo ni maombi ambayo yameandikwa
katika lugha ya asili ya kifaa hicho.

1121
00:49:58,040 --> 00:50:02,190
Hivyo asili Lengo-C au Swift
kanuni, au katika Java, au katika C #.

1122
00:50:02,190 --> 00:50:06,900
Ambayo ina maana wakati wewe download, hebu
kusema Snapchat, maombi maarufu,

1123
00:50:06,900 --> 00:50:10,060
au wakati wewe download
Picha kwa ajili ya simu,

1124
00:50:10,060 --> 00:50:13,270
wewe ni kushusha ama
version yameandikwa kwa ajili ya iPhone yako,

1125
00:50:13,270 --> 00:50:16,830
au kuandikwa ajili ya simu yako Android,
au kuandikwa kwa uso wako.

1126
00:50:16,830 --> 00:50:18,500
>> Lakini kuna njia mbadala.

1127
00:50:18,500 --> 00:50:26,020
Kama Olivier alirejelea,
unaweza kweli kutumia HTML 5

1128
00:50:26,020 --> 00:50:33,440
badala yake, kwa kutumia kile kinachoitwa mtandao
maombi, ambapo wewe tu

1129
00:50:33,440 --> 00:50:35,940
kutekeleza uwepo yako ya mkononi
na utendaji yoyote.

1130
00:50:35,940 --> 00:50:37,030
Je, ina maana na uwepo mkononi?

1131
00:50:37,030 --> 00:50:39,800
Kama tovuti yako ambayo ina yako
mawasiliano ya habari, orodha ya yote

1132
00:50:39,800 --> 00:50:43,049
bidhaa yako, labda ni ina ununuzi
gari, labda wewe kuuza vitu kwa njia hiyo.

1133
00:50:43,049 --> 00:50:46,850
Chochote maombi yako ni, wewe
kutekeleza, si katika Lengo-C,

1134
00:50:46,850 --> 00:50:51,200
au Swift, au Java, au C #, lakini katika HTML
5, ambayo ilikuwa lugha sisi inaonekana

1135
00:50:51,200 --> 00:50:55,470
katika jana, na JavaScript na CSS.

1136
00:50:55,470 --> 00:50:58,700
>> Na nini ni nzuri kuhusu wale
tatu ni kwamba kukimbia nao,

1137
00:50:58,700 --> 00:51:01,981
unahitaji nini tu kipande cha programu?

1138
00:51:01,981 --> 00:51:02,980
Watazamaji: kivinjari.

1139
00:51:02,980 --> 00:51:04,229
DAVID J. Malan: kivinjari.

1140
00:51:04,229 --> 00:51:07,610
Na bora Najua, yote haya
vifaa kuja na browsers mtandao,

1141
00:51:07,610 --> 00:51:10,480
hivyo user hana na
kufunga kitu maalum.

1142
00:51:10,480 --> 00:51:12,920
Hivyo unaweza tu kuwaambia yako
watazamaji, wateja wako,

1143
00:51:12,920 --> 00:51:16,590
kwenda acme.com katika yako
browser na utasikia tu

1144
00:51:16,590 --> 00:51:19,730
na mtandao msingi uzoefu
kwamba bado inajaza screen,

1145
00:51:19,730 --> 00:51:25,100
lakini huna kuwa na wasiwasi kuhusu yote ya
gharama hizi na zote za utata huu.

1146
00:51:25,100 --> 00:51:28,600
Lakini hakika kuna ni kwenda
kwa kuwa ni kukamata hapa, sawa?

1147
00:51:28,600 --> 00:51:31,740
Hasa kama mimi kumweka nje
kwamba miaka kadhaa iliyopita,

1148
00:51:31,740 --> 00:51:35,700
toleo la kwanza sana ya
Facebook ya maombi ya simu

1149
00:51:35,700 --> 00:51:38,810
ilikuwa zaidi HTML 5 maombi.

1150
00:51:38,810 --> 00:51:42,490
Na wao wana, zaidi
Hivi karibuni, reimplemented ni

1151
00:51:42,490 --> 00:51:44,700
katika maombi yao mengine.

1152
00:51:44,700 --> 00:51:46,990
>> Hivyo kwa nini ingekuwa wewe si
mara moja nataka kusema,

1153
00:51:46,990 --> 00:51:49,190
vizuri, ni wazi tunakwenda kufanya hili?

1154
00:51:49,190 --> 00:51:51,560
Nini kinaweza gharama za siri kuwa?

1155
00:51:51,560 --> 00:51:52,477
>> Watazamaji: Utendaji.

1156
00:51:52,477 --> 00:51:53,643
DAVID J. Malan: Utendaji?

1157
00:51:53,643 --> 00:51:54,567
Unamaanisha nini?

1158
00:51:54,567 --> 00:52:01,040
>> Watazamaji: programu ya asili
ina utendaji zaidi.

1159
00:52:01,040 --> 00:52:03,850
>> DAVID J. Malan: Hivyo kwamba ni
kweli, kwa michache ya sababu.

1160
00:52:03,850 --> 00:52:05,270
Tunaweza oversimplify jibu.

1161
00:52:05,270 --> 00:52:08,061
Na kukumbuka mjadala wetu wa
kufasiriwa dhidi lugha ulioandaliwa.

1162
00:52:08,061 --> 00:52:12,030
Hii ni HTML 5 na kwa hayo, tu kuwa
wazi, JavaScript-- kawaida imeandikwa

1163
00:52:12,030 --> 00:52:15,880
JS-- na CSS wote ni
kufasiriwa lugha,

1164
00:52:15,880 --> 00:52:21,020
ingawa tu JavaScript
ni lugha ya programu.

1165
00:52:21,020 --> 00:52:25,820
>> Na hivyo dhidi hayo, ambayo baadhi ya haya
ni ulioandaliwa, angalau hizi three--

1166
00:52:25,820 --> 00:52:29,990
Lengo-C, Java na C # - haya,
katika nadharia, lazima tu kuwa kwa kasi zaidi.

1167
00:52:29,990 --> 00:52:31,670
Lakini kuna ukweli mwingine for--

1168
00:52:31,670 --> 00:52:32,440
>> Watazamaji: Functionalities?

1169
00:52:32,440 --> 00:52:32,830
>> DAVID J. Malan: Nini hiyo?

1170
00:52:32,830 --> 00:52:34,060
>> Watazamaji: Functionalities.

1171
00:52:34,060 --> 00:52:34,570
>> DAVID J. Malan: Utendaji?

1172
00:52:34,570 --> 00:52:35,070
Jinsi gani?

1173
00:52:35,070 --> 00:52:37,305
Watazamaji: Matumizi kamera
mbali ya simu yako au kitu.

1174
00:52:37,305 --> 00:52:41,471
Unaweza kutumia wale walio na browser.

1175
00:52:41,471 --> 00:52:42,470
DAVID J. Malan: Hasa.

1176
00:52:42,470 --> 00:52:43,011
Wao ni sec--

1177
00:52:43,011 --> 00:52:45,034
Watazamaji: [inaudible]

1178
00:52:45,034 --> 00:52:46,700
DAVID J. Malan: Hiyo ni mwingine moja nzuri.

1179
00:52:46,700 --> 00:52:49,230
Kuna sifa ya kuwa kuja
na simu za mkononi leo

1180
00:52:49,230 --> 00:52:53,840
ambayo si, kwa kubuni, kwa ajili ya usalama
Sababu kupatikana kwa browsers mtandao.

1181
00:52:53,840 --> 00:52:56,410
Kwa sababu itakuwa ni aina ya
Jambo creepy kama tu wakati

1182
00:52:56,410 --> 00:53:00,710
wewe kutembelea google.com, au
cnn.com, au yoyote website.com,

1183
00:53:00,710 --> 00:53:04,490
kwamba tovuti hiyo ina nguvu ya kugeuka
kwenye kamera yako, kuchukua picha ya wewe,

1184
00:53:04,490 --> 00:53:06,010
na kisha kuitumia.

1185
00:53:06,010 --> 00:53:09,280
Lakini wewe si unataka tovuti random
kwamba wewe kutembelea kwa mara ya kwanza

1186
00:53:09,280 --> 00:53:10,690
kuwa na kwamba uwezo.

1187
00:53:10,690 --> 00:53:13,460
>> Na hivyo kile simu
wazalishaji kawaida ya kufanya

1188
00:53:13,460 --> 00:53:17,230
ni wao tu kukataa upatikanaji
kwa aina hiyo ya habari

1189
00:53:17,230 --> 00:53:20,650
kwa browser, ambayo ina maana
hawezi kutekeleza kamera.

1190
00:53:20,650 --> 00:53:24,180
Huwezi kutekeleza notisi kushinikiza,
beeps kwamba kupata juu ya screen yako

1191
00:53:24,180 --> 00:53:26,120
na ujumbe mfupi.

1192
00:53:26,120 --> 00:53:31,350
Na kwa kweli, hata GPS ni aina tu
ya aina ya kupatikana kwa browsers mtandao.

1193
00:53:31,350 --> 00:53:34,140
Kama wameweza milele, juu ya mbali
au kwenye simu ya mkononi,

1194
00:53:34,140 --> 00:53:38,770
anapigiwa kitu kama labda
cnn.com, lakini pia vituo habari za mitaa

1195
00:53:38,770 --> 00:53:43,890
huwa na kufanya hivyo, wewe ni ilisababisha
mara nyingi kwa message-- foxnews.com

1196
00:53:43,890 --> 00:53:45,170
anataka kujua eneo lako.

1197
00:53:45,170 --> 00:53:46,610
Kuidhinisha au kukataa.

1198
00:53:46,610 --> 00:53:52,070
>> Naam, browser ni kujaribu kupata
GPS yako habari kutoka simu yako.

1199
00:53:52,070 --> 00:53:54,740
Bali nashiriki Microsoft,
na Apple, na Google

1200
00:53:54,740 --> 00:53:57,330
wameamua kwamba anahisi kama
ni hali muhimu,

1201
00:53:57,330 --> 00:53:59,461
tunataka Google Maps na
zana nyingine ya kufanya kazi,

1202
00:53:59,461 --> 00:54:02,710
lakini hatutaki huenda watu nje
na tu kuwezesha tovuti yoyote ya kufanya hili.

1203
00:54:02,710 --> 00:54:05,934
Basi hebu aina ya kukutana
halfway na kuchochea mtumiaji.

1204
00:54:05,934 --> 00:54:08,850
Lakini si kwamba lazima kesi
na vifaa vyote, kama kamera

1205
00:54:08,850 --> 00:54:10,680
na pamoja na kushinikiza
kuarifiwa na kama,

1206
00:54:10,680 --> 00:54:13,650
hivyo unaweza kuwa na
sadaka makala fulani.

1207
00:54:13,650 --> 00:54:15,100
Lakini utendaji pia.

1208
00:54:15,100 --> 00:54:18,020
Ni kuwa chini
liko siku hizi, labda

1209
00:54:18,020 --> 00:54:22,400
kama LTE upatikanaji wa samaki juu na kwa kasi
kasi internet kwenye simu,

1210
00:54:22,400 --> 00:54:24,110
lakini unaweza aina ya kuhisi tofauti.

1211
00:54:24,110 --> 00:54:28,190
Kama mtandao msingi maombi
tu anahisi polepole, kawaida,

1212
00:54:28,190 --> 00:54:31,100
kuliko maombi ya asili, sehemu
kwa sababu mtandao msingi maombi

1213
00:54:31,100 --> 00:54:32,680
kwa ufafanuzi ni kwenye mtandao.

1214
00:54:32,680 --> 00:54:35,610
Ni akizungumza na servrar kwenye mtandao.

1215
00:54:35,610 --> 00:54:39,590
Na kama muunganiko wa mtandao wako ni
polepole, hata kusogeza inaweza kuwa polepole.

1216
00:54:39,590 --> 00:54:43,710
>> Lakini maombi ya asili, una
tayari kabla ya downloaded-- pengine

1217
00:54:43,710 --> 00:54:45,680
ulipokuwa nyumbani
kutoka programu kuhifadhi,

1218
00:54:45,680 --> 00:54:47,900
au angalau kabla ya kupakuliwa
katika ukamilifu wake

1219
00:54:47,900 --> 00:54:49,640
mapema, chochote yako
uhusiano speed--

1220
00:54:49,640 --> 00:54:52,530
na hivyo sasa una yote ya
bits kwamba kwa ujumla wanahitaji.

1221
00:54:52,530 --> 00:54:55,090
Isipokuwa labda baadhi data
kwamba linatokana na server.

1222
00:54:55,090 --> 00:54:57,130
>> Basi hizi ni biashara awamu ya pili hapa.

1223
00:54:57,130 --> 00:54:59,980
Kuna aina ya katikati
maelewano, kwa kweli.

1224
00:54:59,980 --> 00:55:00,907
Na nadhani you--

1225
00:55:00,907 --> 00:55:02,895
>> Watazamaji: Matumizi offline data.

1226
00:55:02,895 --> 00:55:06,355
Katika programu ya asili, unaweza [inaudible]

1227
00:55:06,355 --> 00:55:07,480
DAVID J. Malan: Ni kweli.

1228
00:55:07,480 --> 00:55:09,730
Hivyo kuna suala now,
ambayo ni kweli annoying

1229
00:55:09,730 --> 00:55:13,120
kama huwezi kucheza baadhi ya mchezo au matumizi
programu baadhi sababu tu wewe ni

1230
00:55:13,120 --> 00:55:15,110
katika basement mahali fulani
au katika lifti.

1231
00:55:15,110 --> 00:55:18,700
maombi ya asili ni resilient
na uwezekano mkubwa dhidi ya kwamba,

1232
00:55:18,700 --> 00:55:20,990
kuchukua una zote
data unahitaji ndani ya nchi.

1233
00:55:20,990 --> 00:55:22,900
>> Kwa hiyo, kuna chaguo la tatu hapa.

1234
00:55:22,900 --> 00:55:30,270
Na hebu kuteka wigo kama
programu ya asili hapa na programu mtandao hapa.

1235
00:55:30,270 --> 00:55:32,460
Na nini katikati
ni kitu called--

1236
00:55:32,460 --> 00:55:35,410
na nadhani unaweza kuwa
alitumia neno kabla, labda?

1237
00:55:35,410 --> 00:55:37,170
Hybrid maombi.

1238
00:55:37,170 --> 00:55:40,980
Na kama neno ina maana,
ni kitu katikati.

1239
00:55:40,980 --> 00:55:46,230
Ni aina ya maombi ya mtandao na
ni aina ya maombi ya asili.

1240
00:55:46,230 --> 00:55:47,690
>> Na hii ina maana gani?

1241
00:55:47,690 --> 00:55:51,750
Ni zinageuka kuna watu frameworks--
kutumia neno kutoka programu earlier--

1242
00:55:51,750 --> 00:55:55,860
kwamba watu wengine wameandika
kwa kila moja ya majukwaa haya.

1243
00:55:55,860 --> 00:55:57,500
Haya na bado vifaa vingine.

1244
00:55:57,500 --> 00:56:02,390
Kwa kweli, napenda kwenda PhoneGap,
ambayo ni moja ya mfumo vile kwamba mimi

1245
00:56:02,390 --> 00:56:04,520
kuamini Adobe anamiliki sasa.

1246
00:56:04,520 --> 00:56:07,830
Hebu kwenda Anza.

1247
00:56:07,830 --> 00:56:09,430
Hebu tuone.

1248
00:56:09,430 --> 00:56:12,450
Kuona kama naweza kuona orodha ya zana.

1249
00:56:12,450 --> 00:56:13,150
Vifaa vya ujenzi.

1250
00:56:13,150 --> 00:56:15,845
Kuanza.

1251
00:56:15,845 --> 00:56:17,570
PhoneGap vifaa.

1252
00:56:17,570 --> 00:56:18,672
>> Hebu tuone.

1253
00:56:18,672 --> 00:56:23,459
PhoneGap vifaa upatikanaji.

1254
00:56:23,459 --> 00:56:26,125
Napenda kuona kama tunaweza kupata kidogo
chati ya waliyo kuwa nayo.

1255
00:56:26,125 --> 00:56:29,170

1256
00:56:29,170 --> 00:56:31,640
Hii ni kwenye tovuti nyingine.

1257
00:56:31,640 --> 00:56:32,525
Je, hii ni muhimu?

1258
00:56:32,525 --> 00:56:33,030
Hakuna

1259
00:56:33,030 --> 00:56:36,330
Hiyo ni gonna kupoteza muda wetu huko.

1260
00:56:36,330 --> 00:56:40,185
PhoneGap vifaa.

1261
00:56:40,185 --> 00:56:40,685
Vifaa.

1262
00:56:40,685 --> 00:56:45,190

1263
00:56:45,190 --> 00:56:48,030
API kifaa.

1264
00:56:48,030 --> 00:56:49,270
Nope, wameweza wakiongozwa yake.

1265
00:56:49,270 --> 00:56:50,070
>> PhoneGap.

1266
00:56:50,070 --> 00:56:54,964
Hebu kwenda moja ya mwisho kuangalia hii
na kuona kama siwezi kuonyesha.

1267
00:56:54,964 --> 00:56:55,630
Kuanza.

1268
00:56:55,630 --> 00:56:58,160

1269
00:56:58,160 --> 00:56:59,020
Kufunga PhoneGap.

1270
00:56:59,020 --> 00:57:02,310

1271
00:57:02,310 --> 00:57:03,270
Kufunga programu ya simu.

1272
00:57:03,270 --> 00:57:04,320
Kuja juu.

1273
00:57:04,320 --> 00:57:07,220

1274
00:57:07,220 --> 00:57:08,580
Wameweza maadili imara kila kitu.

1275
00:57:08,580 --> 00:57:09,750
Sawa.

1276
00:57:09,750 --> 00:57:11,370
Oh, sawa.

1277
00:57:11,370 --> 00:57:12,550
Naam, hapa sisi kwenda.

1278
00:57:12,550 --> 00:57:16,130
Hii si wote kwamba mwangaza, lakini
hii ni nini nilikuwa aina ya kutafuta.

1279
00:57:16,130 --> 00:57:20,940
>> Hivyo PhoneGap ni mfumo kwamba wewe
Unaweza kushusha kwa bure kwamba anatoa

1280
00:57:20,940 --> 00:57:22,750
baadhi ya kanuni starter, kimsingi.

1281
00:57:22,750 --> 00:57:26,600
Hivyo baadhi ya kanuni kwamba wao wameandika
hiyo haina kufanya mengi ya kitu chochote.

1282
00:57:26,600 --> 00:57:29,610
Lakini nini anatoa wewe
kimsingi ni sawa

1283
00:57:29,610 --> 00:57:34,910
ya maombi ambayo tu unaweka
Mstatili kubwa juu ya screen ya mtumiaji.

1284
00:57:34,910 --> 00:57:38,040
Haina kuweka URL bar, kama
browser, haina kuweka mahali.

1285
00:57:38,040 --> 00:57:39,650
Ni tu unaweka Mstatili kubwa.

1286
00:57:39,650 --> 00:57:43,230
Na wewe configure hii kubwa
mstatili, chini ya Hood,

1287
00:57:43,230 --> 00:57:50,780
kwa kweli kwenda acme.com, au labda
m.acme.com, kwa mobile.acme.com,

1288
00:57:50,780 --> 00:57:52,910
lakini user hajui
wao uko katika anwani hiyo.

1289
00:57:52,910 --> 00:57:55,520
All wao kuona ni
yaliyomo ya ukurasa wa mtandao.

1290
00:57:55,520 --> 00:57:59,822
>> Lakini nini ni nzuri kuhusu kiumbe hiki
programu ya mseto ni kwamba kile PhoneGap

1291
00:57:59,822 --> 00:58:03,030
na makampuni mengine ni kutoa ni
wao ni kutoa kidogo ya kificho

1292
00:58:03,030 --> 00:58:05,760
katika Lengo-C au Swift, au
kidogo ya kificho katika Java,

1293
00:58:05,760 --> 00:58:08,320
au kidogo ya kificho
katika C #, na kimsingi,

1294
00:58:08,320 --> 00:58:12,990
wote una kutoa ni ya chini
pepe ya mtandao maombi yako msingi.

1295
00:58:12,990 --> 00:58:15,750
Na kisha kifungu hii
wote pamoja na wewe

1296
00:58:15,750 --> 00:58:20,670
kuwa ni ama kupata yako
tovuti kupitia mtandao,

1297
00:58:20,670 --> 00:58:24,060
au hata cache za mitaa
nakala ndani ya maombi,

1298
00:58:24,060 --> 00:58:28,690
na kisha kuokoa maombi yako
katika format iPhone, Android simu

1299
00:58:28,690 --> 00:58:32,030
format, uso format, au
idadi yoyote ya vifaa vingine.

1300
00:58:32,030 --> 00:58:34,960
>> You kupakia kila mmoja matoleo wale
kwa Hifadhi Play Google,

1301
00:58:34,960 --> 00:58:37,690
wa Hifadhi App, kwa
Windows Hifadhi, na kadhalika.

1302
00:58:37,690 --> 00:58:41,570
Na sasa, unaweza kuwa na yote ya yako
watazamaji kushusha kweli programu ya asili,

1303
00:58:41,570 --> 00:58:44,250
japo wengi wa kanuni mara
imeandikwa na mtu mwingine,

1304
00:58:44,250 --> 00:58:49,090
lakini yaliyomo ya programu kwamba asili zote
kuja kutoka, kwa kawaida, tovuti yako mwenyewe.

1305
00:58:49,090 --> 00:58:53,950
Hivyo kuendelea kuandika tovuti yako
katika HTML, JavaScript, na CSS.

1306
00:58:53,950 --> 00:58:56,400
>> Hivyo kwa nini blur mistari haya?

1307
00:58:56,400 --> 00:59:00,240
Kwa nini kuwa na maombi ya mseto
hiyo ni aina ya asili, lakini pia

1308
00:59:00,240 --> 00:59:02,569
aina ya mtandao msingi?

1309
00:59:02,569 --> 00:59:04,610
Nini ni hatua nzima ya
kuongeza utata huu?

1310
00:59:04,610 --> 00:59:07,180
I mean, hata bado, tu kutoka
glancing kupitia ukurasa huu,

1311
00:59:07,180 --> 00:59:11,790
Anza mwongozo anahisi kama
ni got mengi yote ya hatua kwa ajili yangu

1312
00:59:11,790 --> 00:59:13,514
kufanya kabla ya mimi can--

1313
00:59:13,514 --> 00:59:14,430
Watazamaji: reusability?

1314
00:59:14,430 --> 00:59:14,960
DAVID J. Malan: reusability?

1315
00:59:14,960 --> 00:59:15,618
Unamaanisha nini?

1316
00:59:15,618 --> 00:59:16,826
>> Watazamaji: Of kanuni chanzo.

1317
00:59:16,826 --> 00:59:19,438
Hivyo kificho huo bila kukimbia kwenye
majukwaa yote tofauti.

1318
00:59:19,438 --> 00:59:20,313
DAVID J. Malan: Yeah.

1319
00:59:20,313 --> 00:59:21,188
Watazamaji: [inaudible]

1320
00:59:21,188 --> 00:59:23,200

1321
00:59:23,200 --> 00:59:24,200
DAVID J. Malan: Perfect.

1322
00:59:24,200 --> 00:59:26,930
Kama muda ni tight na kama wewe
hawana kwamba developers-- wengi

1323
00:59:26,930 --> 00:59:28,900
labda una developer moja
na yeye au yeye hakika

1324
00:59:28,900 --> 00:59:31,050
hajui yote haya
environments-- hakika si vizuri,

1325
00:59:31,050 --> 00:59:33,341
na kwa hakika hawawezi mpango
katika zote tatu wakati huo huo

1326
00:59:33,341 --> 00:59:35,970
na meli bidhaa tatu katika
wakati kuruhusiwa kwa moja,

1327
00:59:35,970 --> 00:59:40,360
unaweza kuwa kwake kujenga kila kitu
katika HTML na JavaScript na CSS,

1328
00:59:40,360 --> 00:59:43,260
na kisha kujifunza kidogo kidogo
kidogo kuhusu programu ya asili,

1329
00:59:43,260 --> 00:59:45,930
kutosha tu kushusha
mfumo kama huu,

1330
00:59:45,930 --> 00:59:48,750
na kisha upload bidhaa yako kwa
yote ya maduka mbalimbali programu

1331
00:59:48,750 --> 00:59:51,700
hivyo kwamba sasa una
maombi ya asili.

1332
00:59:51,700 --> 00:59:54,090
>> Hivyo kwamba inaonekana kama kushinda na kushinda,
lakini tena, kuwa wazi,

1333
00:59:54,090 --> 00:59:56,540
kile ni uwezo
gharama au gotchas?

1334
00:59:56,540 --> 01:00:00,292

1335
01:00:00,292 --> 01:00:01,209
>> Watazamaji: Utendaji?

1336
01:00:01,209 --> 01:00:02,083
DAVID J. Malan: Yeah.

1337
01:00:02,083 --> 01:00:02,959
Utendaji.

1338
01:00:02,959 --> 01:00:04,250
Ni vigumu kuelezea kwa maneno.

1339
01:00:04,250 --> 01:00:07,590
Hivyo kama wewe tu kuchukua
imani maombi ya simu,

1340
01:00:07,590 --> 01:00:11,430
maombi ya mtandao mapenzi
kawaida kufanya zaidi polepole.

1341
01:00:11,430 --> 01:00:16,500
Ni wanaweza kuangalia haki kabisa, kwa sababu
katika iPhone, na katika simu za Android,

1342
01:00:16,500 --> 01:00:19,210
na vifaa Windows, kuna
daima aina ya chaguo-msingi kuangalia

1343
01:00:19,210 --> 01:00:21,780
na kujisikia wote wa
vifungo na menus.

1344
01:00:21,780 --> 01:00:25,160
>> Na makampuni katika mtandao, unaweza kujaribu
kwa takriban aesthetics wale

1345
01:00:25,160 --> 01:00:28,329
na maktaba kama Bootstrap,
lakini user-- user-- wajanja

1346
01:00:28,329 --> 01:00:30,620
ni kwenda kujua kwamba
kitu si haki kabisa hapa.

1347
01:00:30,620 --> 01:00:32,510
Na hiyo ni nzuri, labda
si kwamba mpango kubwa.

1348
01:00:32,510 --> 01:00:35,500
Lakini suala utendaji
kabisa ni kubwa mpango huo.

1349
01:00:35,500 --> 01:00:39,400
maombi ya asili huwa na tu
kuwa zaidi msikivu na kwa hiyo

1350
01:00:39,400 --> 01:00:39,946
bora zaidi.

1351
01:00:39,946 --> 01:00:42,070
Na hivyo, ni nini basi inaweza kuwa
bora wa walimwengu wote?

1352
01:00:42,070 --> 01:00:44,584
Kama uko hasa ndogo
kampuni au kikundi kidogo,

1353
01:00:44,584 --> 01:00:47,000
huna rasilimali
kuendeleza programu katika sambamba

1354
01:00:47,000 --> 01:00:50,480
kwenye majukwaa zote tatu, na kusema ukweli,
anahisi kama hiyo ni wazo mbaya anyway

1355
01:00:50,480 --> 01:00:53,526
kwa sababu kama wewe roll nje na juu ya
zote tatu wakati huo huo kutambua,

1356
01:00:53,526 --> 01:00:56,400
tunapaswa kuwa aliongeza baadhi ya vipengele
au amefanya kitu tofauti, sasa

1357
01:00:56,400 --> 01:00:59,530
una kurekebisha katika
maeneo matatu, hakuna hata mmoja.

1358
01:00:59,530 --> 01:01:02,390
Nini labda mojawapo
mkakati hapa kwa ujumla,

1359
01:01:02,390 --> 01:01:04,130
kama rasilimali na muda ni tight?

1360
01:01:04,130 --> 01:01:06,420
>> Watazamaji: Tu kufanya hivyo juu ya iOS.

1361
01:01:06,420 --> 01:01:08,390
>> DAVID J. Malan: Hiyo si maana.

1362
01:01:08,390 --> 01:01:10,670
iphone, angalau katika
Marekani, ni super maarufu.

1363
01:01:10,670 --> 01:01:13,820
Android bado inaonekana kuwa kubwa
soko, kimataifa, kwa ujumla.

1364
01:01:13,820 --> 01:01:16,740
Hivyo si
lazima mwakilishi

1365
01:01:16,740 --> 01:01:19,210
ya ukamilifu wa duniani wiki hii.

1366
01:01:19,210 --> 01:01:21,180
Lakini hiyo ni kabisa uamuzi mmoja.

1367
01:01:21,180 --> 01:01:23,620
I mean, juu ya chuo hapa mimi
kufikiri baadhi ya idadi mauaji

1368
01:01:23,620 --> 01:01:26,600
au asilimia ya wanafunzi wa vyuo vikuu
na iphone na simu si Android.

1369
01:01:26,600 --> 01:01:28,490
Lakini nje ya nchi, ni aina ya kinyume.

1370
01:01:28,490 --> 01:01:30,040
Hivyo kuamua msingi watazamaji wako.

1371
01:01:30,040 --> 01:01:31,990
Jinsi gani unaweza kujua nini watazamaji wako ana?

1372
01:01:31,990 --> 01:01:34,080
>> Naam, sisi kujifunza hila jana.

1373
01:01:34,080 --> 01:01:35,060
Ungeweza kuwaambia.

1374
01:01:35,060 --> 01:01:37,910
Kama una watazamaji mateka
unaweza kuwatuma fomu ya utafiti.

1375
01:01:37,910 --> 01:01:39,172
Au unaweza tu kufanya nini?

1376
01:01:39,172 --> 01:01:40,076
>> Watazamaji: Google Analytics?

1377
01:01:40,076 --> 01:01:40,680
>> DAVID J. Malan: Nini hiyo?

1378
01:01:40,680 --> 01:01:41,876
>> Watazamaji: Google Analytics.

1379
01:01:41,876 --> 01:01:43,250
DAVID J. Malan: Google Analytics.

1380
01:01:43,250 --> 01:01:43,750
Yeah.

1381
01:01:43,750 --> 01:01:46,970
Au hata aina zaidi ya kitaalam, tu
kuangalia mtandao wako server magogo mwenyewe.

1382
01:01:46,970 --> 01:01:49,100
Kwa sababu kile kinachotokea
kila wakati browser,

1383
01:01:49,100 --> 01:01:51,880
iwapo mbali, desktop au
simu kutembelea tovuti yako?

1384
01:01:51,880 --> 01:01:56,847
Wao kutuma kwamba HTTP header kwamba inaonyesha
nini browser na OS wao ni kutumia.

1385
01:01:56,847 --> 01:02:00,180
Hivyo unaweza infer, na uwezekano mkubwa,
nini idadi ya watu wako ni kutumia njia hiyo

1386
01:02:00,180 --> 01:02:01,410
na kisha kurekebisha.

1387
01:02:01,410 --> 01:02:03,030
>> Hivyo kudhani kuwa suala lisilokubalika.

1388
01:02:03,030 --> 01:02:07,760
Hiyo ni aina ya mbaya kwa ajili ya biashara kama
watumiaji Android hawezi kununua vilivyoandikwa yetu.

1389
01:02:07,760 --> 01:02:10,942
>> Watazamaji: Kama wewe ni
gonna malipo au la?

1390
01:02:10,942 --> 01:02:12,900
DAVID J. Malan: Kama
wewe ni kwenda malipo?

1391
01:02:12,900 --> 01:02:14,900
Hivyo OK, unaweza kupata nini kulipia.

1392
01:02:14,900 --> 01:02:18,400
>> Watazamaji: Kama programu yako ni gonna
kuwa huru au kama ni gonna--

1393
01:02:18,400 --> 01:02:19,530
>> DAVID J. Malan: Sawa.

1394
01:02:19,530 --> 01:02:21,920
Hivyo labda unaweza recoup
gharama kwa njia hiyo, or--?

1395
01:02:21,920 --> 01:02:26,195
>> Watazamaji: Nilisoma somo mara moja kuwa alisema
zaidi ya watumiaji Apple kulipa kwa ajili ya programu versus--

1396
01:02:26,195 --> 01:02:28,320
DAVID J. Malan: Hiyo ni kweli
kwa sababu wao uko tayari

1397
01:02:28,320 --> 01:02:29,640
kulipa zaidi kwa ajili ya vifaa vyao.

1398
01:02:29,640 --> 01:02:31,295
Hivyo haina maana dhana.

1399
01:02:31,295 --> 01:02:32,170
>> Watazamaji: [inaudible]

1400
01:02:32,170 --> 01:02:34,439

1401
01:02:34,439 --> 01:02:35,230
DAVID J. Malan: Sawa.

1402
01:02:35,230 --> 01:02:38,667
Hivyo kama wao ni zaidi tayari kulipa,
kisha mpaka kuzimu, pamoja watumiaji Android.

1403
01:02:38,667 --> 01:02:40,500
Wao siyo kwenda
kutulipa chochote anyway.

1404
01:02:40,500 --> 01:02:43,499
Tunaweza pia kuzingatia vipaumbele vyetu,
angalau kwa miezi michache ya kwanza

1405
01:02:43,499 --> 01:02:44,810
au mwaka, juu ya iOS.

1406
01:02:44,810 --> 01:02:46,240
Kabisa nafuu.

1407
01:02:46,240 --> 01:02:48,558
Nini umoja zaidi
mkakati kuliko hayo?

1408
01:02:48,558 --> 01:02:53,740

1409
01:02:53,740 --> 01:02:54,960
Maybe-- nini hiyo?

1410
01:02:54,960 --> 01:02:57,040
>> Watazamaji: [inaudible]

1411
01:02:57,040 --> 01:03:00,142
>> DAVID J. Malan: expensive-- zaidi
hivyo labda kuwekeza zaidi in-- kwenda mbele.

1412
01:03:00,142 --> 01:03:00,767
Watazamaji: Yeah.

1413
01:03:00,767 --> 01:03:02,050
Tu tovuti ya mkononi.

1414
01:03:02,050 --> 01:03:03,966
>> DAVID J. Malan: Hivyo kufanya
tovuti ya simu na si

1415
01:03:03,966 --> 01:03:05,440
hata wasiwasi kuhusu utata huu.

1416
01:03:05,440 --> 01:03:07,970
Au labda mkakati kuridhisha,
ambayo hata Facebook alichukua,

1417
01:03:07,970 --> 01:03:10,890
ni kuanza na mseto
maombi kwa sababu si

1418
01:03:10,890 --> 01:03:13,582
kuwa vigumu sana kufanya hivyo kuliko huu.

1419
01:03:13,582 --> 01:03:16,040
Wewe tu na kusoma baadhi
nyaraka na kufikiri jinsi

1420
01:03:16,040 --> 01:03:17,480
kupakia mambo ya Hifadhi App.

1421
01:03:17,480 --> 01:03:19,670
Hivyo labda wewe kuanza na
huu, ili siku moja,

1422
01:03:19,670 --> 01:03:21,112
unaweza kusaidia yote ya watumiaji yako.

1423
01:03:21,112 --> 01:03:23,570
Na kisha, tu kama Picha
na makampuni mengine wamefanya,

1424
01:03:23,570 --> 01:03:25,330
wakati una rasilimali,
una watu,

1425
01:03:25,330 --> 01:03:27,660
kwa nini sio wewe tena kutekeleza
tu iOS maombi.

1426
01:03:27,660 --> 01:03:31,460
Bado una kitu kwa kila mtu,
hata kama ni uzoefu duni

1427
01:03:31,460 --> 01:03:33,330
pengine, na maombi ya mseto.

1428
01:03:33,330 --> 01:03:36,770
Lakini unaweza hatua kwa hatua unaendelea nje
na badala yako ya muda mfupi

1429
01:03:36,770 --> 01:03:40,280
hatua ya programu ya mseto na
yako maombi zaidi ya asili.

1430
01:03:40,280 --> 01:03:44,090
>> Watazamaji: Lakini kwa mseto programu
utakuwa na upatikanaji wa makala ya mkononi?

1431
01:03:44,090 --> 01:03:45,440
>> DAVID J. Malan: Si lazima.

1432
01:03:45,440 --> 01:03:47,810
Hivyo labda wewe kufanya
fahamu uamuzi mapema,

1433
01:03:47,810 --> 01:03:51,930
unaweza tu kupakia picha juu ya
uliotokea iPhone maombi kwa ajili ya Facebook,

1434
01:03:51,930 --> 01:03:56,060
lakini si juu ya maombi Android,
awali, kwa mfano.

1435
01:03:56,060 --> 01:04:00,600
Na kwamba ni kidogo ya uongo nyeupe kwa sababu
maombi ya mtandao kuwa na vikwazo zaidi

1436
01:04:00,600 --> 01:04:03,620
kuliko maombi ya mseto ni zamu
nje, na kama sisi kusoma nyaraka

1437
01:04:03,620 --> 01:04:07,260
kwa PhoneGap na mambo kama hayo,
watu wamekuja na njia

1438
01:04:07,260 --> 01:04:11,110
kutoa maombi mtandao msingi
kufikia kamera,

1439
01:04:11,110 --> 01:04:13,310
hivyo muda mrefu kama unatumia
maombi ya mseto.

1440
01:04:13,310 --> 01:04:14,214
>> Jinsi gani kwamba kazi?

1441
01:04:14,214 --> 01:04:16,130
Kwa sababu ya mseto
maombi, kwa ufafanuzi,

1442
01:04:16,130 --> 01:04:19,600
ina kidogo ya kificho katika Lengo-C,
na Swift, na Java, au katika C #,

1443
01:04:19,600 --> 01:04:20,920
wanaweza kupata vifaa.

1444
01:04:20,920 --> 01:04:24,590
Si lazima kila kitu,
lakini ili vizuri sana

1445
01:04:24,590 --> 01:04:27,310
kuwa kesi hiyo una
kutosha upatikanaji wa kupata kamera,

1446
01:04:27,310 --> 01:04:32,960
hata kwa majukwaa Android, kwa
mfano, katika mfano kwamba contrived.

1447
01:04:32,960 --> 01:04:35,515
>> Maswali yoyote mengine?

1448
01:04:35,515 --> 01:04:36,279
Sawa.

1449
01:04:36,279 --> 01:04:38,070
Mbona sisi kuchukua yetu
15 dakika kuvunja hapa.

1450
01:04:38,070 --> 01:04:44,060
Tutaweza kuanza saa tatu na ya mwisho
kuangalia programu ya mtandao, database,

1451
01:04:44,060 --> 01:04:45,910
na Javascript.

1452
01:04:45,910 --> 01:04:48,877
