U din hija xi ħaġa
jiswew jżomm f'moħħu,

609
00:26:20,560 --> 00:26:24,410
minn perspettiva ta 'negozju, li
huwa faċli ħafna għall-persuni tekniċi

610
00:26:24,410 --> 00:26:26,900
biex tikseb kollha maħduma bl tagħhom
opinjonijiet dwar ċerti affarijiet.

611
00:26:26,900 --> 00:26:29,566
U dan ma jfissirx neċessarjament
li l-waħda yelling l-iktar volum għoli

628
00:27:11,310 --> 00:27:15,390

għalhekk huwa kien madwar għal żmien pjuttost twil.

Nixtieq sejħa jQuery librerija, fejn
darb'oħra librerija hija biss mazz ta 'kodiċi

għalik li tagħmel xogħol tiegħek.

662
00:28:57,760 --> 00:29:00,820
U let me do eżempju wieħed ta '
dan fil-kuntest tal-web.

663

>> Fil-kuntest tal-internet hemm
din il-lingwa, JavaScript,

00:29:03,910 --> 00:29:06,690
li aħna ser tara wara, fejn inti
jista 'jgħid xi ħaġa simili this--

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

666
00:29:10,060 --> 00:29:11,490
U dak li għamlet I call it bieraħ?

667
00:29:11,490 --> 00:29:16,800
L-ewwel, I think, kien l-ID uniku I taw
ma 'element li ħares bħal dan.

668
00:29:16,800 --> 00:29:23,110
"P id =" ewwel ">" u mbagħad kellna
bħal "ipsum Lorem," eċċetera.

669
00:29:23,110 --> 00:29:28,210
Mela jekk jien kienu kitba ta 'programm
JavaScript li b'xi mod jimmanipulaw,

670
00:29:28,210 --> 00:29:30,830
jibdlu l-paġni web li aħna
kienu jilagħbu ma bieraħ,

671
00:29:30,830 --> 00:29:33,010
Nixtieq jużaw dan
linja enfasizzat tal-kodiċi

biex tikseb dak snippet partikolari ta HTML
minn paġna tiegħi, li node partikolari,

00:29:38,700 --> 00:29:39,680

Huwa inqas kodiċi.

686

Huwa biss aktar malajr għat-tip.

00:30:09,070 --> 00:30:11,690
Il kontropunt hija
li jidher scarier.

Inti ma tistax verament taqrah xellug għal-lemin.

689
00:30:13,540 --> 00:30:16,730
Fil-fatt, għaliex dan huwa l-aktar
punteġġjatura issa minflok ta 'attwali kliem,

690
00:30:16,730 --> 00:30:20,950
I tista 'tip ta jiddeduċu li

bħal jQuery.

696
00:30:31,440 --> 00:30:34,700
Iżda r-realtà hija jQuery għandha tip
ta jsiru standard de facto,

b'tali mod li kważi ħadd dawn
jiem li jikteb kodiċi JavaScript

bhalu, u mhux aktar jikteb

699
00:30:41,520 --> 00:30:45,200

Allura Ruby fuq binarji hija
komunement użati espressjoni.

Wkoll f'din id-dinja, let me
ċirku Java għall-għalf tal-web,

ta 'dak li jfisser li tuża librerija.

Naħseb li l-buttuna kienet griża bi

Per eżempju, komuni ħafna huwa
drop down menus bħal dan.

Dan ikun assoluta
uġigħ biex jiġu implimentati.

817
00:36:11,560 --> 00:36:13,610
U ma kienx dak twil
ilu li aħna programmaturi

818
00:36:13,610 --> 00:36:16,490
jkollhom jimplimentaw dawn
tipi ta 'menus mill-bidu nett.

819
00:36:16,490 --> 00:36:20,800

drop down menu ferm, ferm aktar faċli.

821
00:36:25,230 --> 00:36:27,850
M'hemm l-ebda mod wieħed biex tagħmel dan,
imma jekk Naqra id-dokumentazzjoni

822
00:36:27,850 --> 00:36:32,100
Jiena nara li, OK, I għandhom jużaw
dan il HTML jekk irrid drop down menu

Jekk irrid li dan dehra ta 'buttuna

00:46:23,900 --> 00:46:28,238
Imbagħad fid-dinja Android,
f'liema lingwa ma Android użu?

1043
00:46:28,238 --> 00:46:30,618
>> UDJENZA: C #?

1044
00:46:30,618 --> 00:46:31,570
>> UDJENZA: Java.

1045
00:46:31,570 --> 00:46:34,230
>> DAVID J. Malan: Java hi
il-lingwa ta ' "du jour."

1046
00:46:34,230 --> 00:46:37,950
Fid-dinja Windows, żgur,
aħna ser ngħidu C # f'dak il-każ.

1047
00:46:37,950 --> 00:46:40,590
Allura diġà dan hu tip ta '
tedjanti, għaliex x'hemm

1048
00:46:40,590 --> 00:46:43,070
il takeaway għal negozju
sid jew xi ħadd li sempliċiment

1049
00:46:43,070 --> 00:46:44,570
trid roll out preżenza mobbli?

1050
00:46:44,570 --> 00:46:45,220
Bħal, kkritikat dan?

1051
00:46:45,220 --> 00:46:48,590
Bħal, jekk irrid biex tappoġġja
bażi pjuttost wiesgħa utent,

1052
00:46:48,590 --> 00:46:52,180
I jkollhom jiktbu, jidher,
tliet applikazzjonijiet separati.

1053
00:46:52,180 --> 00:46:55,630
Wieħed minn kull waħda minn dawn il-lingwi,
wieħed fl Java, wieħed fis-C #.

1054
00:46:55,630 --> 00:46:59,620
U anki jekk irrid il-funzjonalità
li jkun identiku, ma jimpurtax.

1055
00:46:59,620 --> 00:47:02,940
I għad għandhom bżonn biex jużaw differenti
lingwi peress Apple, u Microsoft,

1056
00:47:02,940 --> 00:47:06,084
u Google appoġġ kollu
ambjenti differenti.

1057
00:47:06,084 --> 00:47:07,750
U din kienet sfida għal ħafna snin.

1058
00:47:07,750 --> 00:47:10,100
Lura fil-ġurnata, meta
nies użati biex jixtru softwer

1059
00:47:10,100 --> 00:47:12,230
fil-maħżen tal-kompjuter fil
shrink kaxxi mgeżwra,

1060
00:47:12,230 --> 00:47:14,470
inti se jkollha jew li
jilħqu għall-ixkaffa Mac,

1061
00:47:14,470 --> 00:47:19,040
jew for-- forsi dan mac żgħir ħafna
shelf-- jew l-ixkaffa Windows akbar

1062
00:47:19,040 --> 00:47:19,980
u jixtru xi softwer.

1063
00:47:19,980 --> 00:47:22,813
U ħafna drabi, ma kienx hemm anke
xejn għalik fuq l-ixkaffa Mac.

1064
00:47:22,813 --> 00:47:23,430
Għaliex?

1065
00:47:23,430 --> 00:47:26,900
Ukoll, kumpanniji ddeċidew jekk 90%
tad-dinja, 95% tad-dinja

1066
00:47:26,900 --> 00:47:31,180
għandha PCs, għaliex jolqot anki
timplimenta affarijiet fuq Mac OS?

1067
00:47:31,180 --> 00:47:34,370
>> Bħala aside-- total
digression-- għaliex hi

1068
00:47:34,370 --> 00:47:40,960
li Mac jidher hekk impervja virus,
u dud, u theddid għas-sigurtà?

1069
00:47:40,960 --> 00:47:44,040
Huwa Apple aħjar fuq dan?

1070
00:47:44,040 --> 00:47:45,934
Aħjar fil-żamma kompjuters sigura?

1071
00:47:45,934 --> 00:47:47,750
>> UDJENZA: udjenza iżgħar?

1072
00:47:47,750 --> 00:47:50,720
>> DAVID J. Malan: Li
probabbilment l-ftit akbar lilha.

1073
00:47:50,720 --> 00:47:54,740
Allura l-ħafna utenti tal MACs jkollhom
twil sostniet, oh, jużaw Mac,

1074
00:47:54,740 --> 00:47:57,630
inti ser tkun immuni għall-viruses, u
dud, u kollha ta 'dawn l-affarijiet

1075
00:47:57,630 --> 00:47:59,180
li ilhom PCs pjaga.

1076
00:47:59,180 --> 00:48:02,050
Li jista 'jkun minħabba Apple
għandha programmaturi aħjar

1077
00:48:02,050 --> 00:48:05,250
u jiktbu softwer aħjar, jew il-
sistema operattiva kienet imfassla aħjar.

1078
00:48:05,250 --> 00:48:06,870
Forsi, iżda probabbilment mhux.

1079
00:48:06,870 --> 00:48:10,840
>> Huwa probabbilment li meta int
12-il sena, jew 30 xi ħaġa

00:48:10,840 --> 00:48:13,510
tip ta 'seduta fil-kitba dar

varjanti tiegħu.

1084
00:48:21,740 --> 00:48:23,800
Allura hemm xi ftit miż-żewġ naħat.

1085
00:48:23,800 --> 00:48:25,710
Iżda għall-kreditu tagħhom,
Apple, sa fejn naf jien,

00:48:25,710 --> 00:48:28,270
ma verament touted infushom
bħala aktar sigura,

1087
00:48:28,270 --> 00:48:32,110
peress li int biss tistieden drama jekk
inti tagħmel din it-talba, jiena naħseb.

1088
00:48:32,110 --> 00:48:32,610
>> Kull dritt.

1089
00:48:32,610 --> 00:48:36,490
Mingħajr ma jkollna wisq isfel
li, kif nistgħu issolvi din?

1090
00:48:36,490 --> 00:48:39,670
Do ikollok biex jixtru jew għandek biex
tħallas tliet persuni differenti sabiex jiżviluppaw

1091
00:48:39,670 --> 00:48:41,540
apps tiegħek?

1092
00:48:41,540 --> 00:48:42,870
Do you pick wieħed fuq l-ieħor?

1093
00:48:42,870 --> 00:48:45,460

00:48:48,460 --> 00:48:51,001

1097
00:48:51,001 --> 00:48:51,500
Nope.

DAVID J. Malan: Come mal-hardware?

1101
00:48:58,510 --> 00:48:59,533
Xi trid tfisser?

1102

DAVID J. Malan: Allura dan huwa veru.

1105
00:49:06,200 --> 00:49:09,280
Iżda l-klijenti tiegħek,
sadanittant, jista 'jkollhom iPhones,

1106
00:49:09,280 --> 00:49:13,530
li jista 'jkollhom telefowns Android, huma
jista 'jkollhom pilloli magħmula minn Microsoft.

1107
00:49:13,530 --> 00:49:19,040
Allura kif taħseb li għandek strateġija mobbli
għall kollha ta 'dawn l-utenti differenti?

1108
00:49:19,040 --> 00:49:23,320
Jidher li jekk l-ispejjeż,
ejja ngħidu $ 1,000 sa tagħmel iPhone

1109
00:49:23,320 --> 00:49:25,940
applikazzjoni, li għaddej
li jiswik $ 2,000 sa tagħmel

biex jappoġġaw ukoll mezzi Windows kif ukoll.

1112

le, inti jista 'jkollhom website jirrispondu.

1115
00:49:41,065 --> 00:49:41,940
DAVID J. Malan: Tajba.

1116

00:49:46,255 --> 00:49:47,130
DAVID J. Malan: Yeah.

1118
00:49:47,130 --> 00:49:50,260
Allura fil dan kollu kuntest hawn,
aħna kont qed jitkellem dwar dak

1119
00:49:50,260 --> 00:49:53,190
nies kieku ssejjaħ applikazzjonijiet indiġeni.

1120
00:49:53,190 --> 00:49:58,040
Dan huwa l-applikazzjonijiet li huma miktuba
fil-lingwa nattiva ta 'dak l-apparat.

1121
00:49:58,040 --> 00:50:02,190
Allura nattiv Objettiv-C jew Swift
kodiċi, jew fl Java, jew C #.

1122
00:50:02,190 --> 00:50:06,900
Li jfisser meta inti download, ejja
jgħidu Snapchat, applikazzjoni popolari,

1123
00:50:06,900 --> 00:50:10,060
jew meta inti download
Facebook għal telefon,

1124
00:50:10,060 --> 00:50:13,270
inti tniżżil jew l
Verżjoni bil-miktub għall iPhone tiegħek,

1125
00:50:13,270 --> 00:50:16,830
jew bil-miktub għall-telefon Android tiegħek,
jew bil-miktub għall-wiċċ tiegħek.

1126
00:50:16,830 --> 00:50:18,500
>> Iżda hemm alternattiva.

1127
00:50:18,500 --> 00:50:26,020
Kif Olivier kien jalludi għal,
inti tista 'attwalment jużaw HTML 5

1128
00:50:26,020 --> 00:50:33,440
minflok, bl-użu dak li sejjaħ web
applikazzjoni, li biha inti sempliċiment

1129
00:50:33,440 --> 00:50:35,940
jimplimentaw preżenza tiegħek mobbli
u kull funzjonalità.

1130
00:50:35,940 --> 00:50:37,030
What do I jfisser minn preżenza mobbli?

1131
00:50:37,030 --> 00:50:39,800
Bħall-website tiegħek li tkun tiegħek
informazzjoni ta 'kuntatt, lista ta' kull

1132
00:50:39,800 --> 00:50:43,049
-prodotti tiegħek, forsi hija għandha xiri
CART, forsi inti tbigħ affarijiet permezz tiegħu.

1133
00:50:43,049 --> 00:50:46,850
Tkun xi tkun l-applikazzjoni tiegħek, inti
jimplimentawha, mhux fil Objettiv-C,

1134
00:50:46,850 --> 00:50:51,200
jew Swift, jew Java, jew C #, iżda fl HTML
5, li kien il-lingwa ħarisna

1135
00:50:51,200 --> 00:50:55,470
fil bieraħ, bil JavaScript u CSS.

1136
00:50:55,470 --> 00:50:58,700
>> U x'hemm sbieħ dwar dawk
tliet huwa li biex imexxuhom,

1137
00:50:58,700 --> 00:51:01,981
għandek bżonn biss dak biċċa ta 'softwer?

1138
00:51:01,981 --> 00:51:02,980
UDJENZA: A web browser.

1139
00:51:02,980 --> 00:51:04,229
DAVID J. Malan: A web browser.

1140
00:51:04,229 --> 00:51:07,610
U l-aħjar naf, dawn kollha
mezzi jiġu mal-web browsers,

1141
00:51:07,610 --> 00:51:10,480
sabiex l-utent ma jkunx għalfejn
jinstallaw xi ħaġa speċjali.

1142
00:51:10,480 --> 00:51:12,920
Allura inti tista 'biss tell tiegħek
udjenza, il-klijenti tiegħek,

1143
00:51:12,920 --> 00:51:16,590
mur acme.com fil tiegħek
browser u tkun taf biss

1144
00:51:16,590 --> 00:51:19,730
jkollhom esperjenza web ibbażat
li għadhom timla l-iskrin,

1145
00:51:19,730 --> 00:51:25,100
imma inti ma għandekx għalfejn tinkwieta dwar kollha ta '
dawn l-ispejjeż u kollha ta 'din il-komplessità.

1146
00:51:25,100 --> 00:51:28,600
Iżda żgur hemm se
li jkun qabda hawn, id-dritt?

1147
00:51:28,600 --> 00:51:31,740
Speċjalment jekk Jiena nenfasizza
li koppja snin ilu,

-ewwel verżjoni ta '
applikazzjoni mobbli Facebook

1149
00:51:35,700 --> 00:51:38,810
kien l-aktar HTML 5 applikazzjoni.

1150
00:51:38,810 --> 00:51:42,490
U dawn ikollhom, aktar
reċentement, reimplemented dan

1151
00:51:42,490 --> 00:51:44,700
f'applikazzjonijiet oħra tagħhom.

1152
00:51:44,700 --> 00:51:46,990
>> Allura għaliex kieku inti ma
immedjatament trid tgħid,

1153
00:51:46,990 --> 00:51:49,190
ukoll, ovvjament aħna qed tmur biex tagħmel dan?

1154
00:51:49,190 --> 00:51:51,560
Liema jista 'l-ispejjeż moħbija jkun?

1155

Xi trid tghid?

1158

għandha aktar prestazzjoni.

1159
00:52:01,040 --> 00:52:03,850

vera, għal ftit ta 'raġunijiet.

1160
00:52:03,850 --> 00:52:05,270
Nistgħu oversimplify-risposta.

1161
00:52:05,270 --> 00:52:08,061
U recall diskussjoni tagħna ta '
interpretat versus lingwi ikkumpilata.

1162
00:52:08,061 --> 00:52:12,030
Dan huwa HTML 5 u ma 'dan, biss li jkun
ċara, JavaScript-- komunement miktub

anki jekk JavaScript biss
hija lingwa ta 'programmar.

Huwa diffiċli biex jiddeskrivu verbalment.

li mhux big deal.
