00:00:00,000 --> 00:00:02,150
>> DAVID Malan: Vipi kuhusu
mtandao ukurasa na picha?

2
00:00:02,150 --> 00:00:05,560
Hebu tuseme kwamba katika, mapema, nimekuwa
tayari kupakuliwa JPEG ya picha

3
00:00:05,560 --> 00:00:07,290
kutoka katika mtandao, kusema, paka.

4
00:00:07,290 --> 00:00:08,650
internet ni kujazwa pamoja nao.

5
00:00:08,650 --> 00:00:10,710
Na nimekuwa kuweka kwamba katika
directory yangu ya umma.

6
00:00:10,710 --> 00:00:13,030
Katika orodha hiyo ya umma,
hebu kuunda ukurasa aitwaye

7
00:00:13,030 --> 00:00:15,630
image.html kama ifuatavyo.

8
00:00:15,630 --> 00:00:18,390
>> Nimekuwa tayari wamezipata mambo kuanza hapa
katika gedit pamoja na baadhi ya vitambulisho wazi na

9
00:00:18,390 --> 00:00:19,540
baadhi ya vitambulisho karibu.

10
00:00:19,540 --> 00:00:23,330
Ndani ya mwili kisha ya ukurasa huu,
hebu kufanya bracket wazi, picha -

11
00:00:23,330 --> 00:00:25,640
tu img, ingawa, si neno kamili -

12
00:00:25,640 --> 00:00:27,940
nafasi alt sawa.

13
00:00:27,940 --> 00:00:31,400
alt inaruhusu mimi kutoa Nakala mbadala
kwa picha hii, tu katika kesi

14
00:00:31,400 --> 00:00:34,360
user hawawezi kweli kuona picha
Mimi nina kuhusu kutoa.

15
00:00:34,360 --> 00:00:38,930
Basi hebu tu kuelezea hili
picha kama Cat Grumpy.

16
00:00:38,930 --> 00:00:42,490
Na sasa hebu bayana kwamba
chanzo cha picha hii, src -

17
00:00:42,490 --> 00:00:46,070
hivyo tena, si kamili
neno, tu src -

18
00:00:46,070 --> 00:00:50,800
sawa na quote, unquote, "cat.jpg",
ambayo tena, ni file kufanyika katika

19
00:00:50,800 --> 00:00:54,220
mapema mimi kupakuliwa katika
saraka hii ya umma.

20
00:00:54,220 --> 00:00:58,860
>> Hebu sasa karibu quotes na
karibu tag kama ifuatavyo.

21
00:00:58,860 --> 00:01:02,650
Fikiria kwamba kwa mfano, kuna
kweli hakuna dhana ya kuanza picha

22
00:01:02,650 --> 00:01:03,710
na kuacha picha.

23
00:01:03,710 --> 00:01:05,560
Ni ama huko, au siyo.

24
00:01:05,560 --> 00:01:09,715
Hivyo najisikia ajabu kidogo kwa
kweli kuwa wazi karibu tag au

25
00:01:09,715 --> 00:01:11,250
tag mwisho kwa ajili ya tag picha hii.

26
00:01:11,250 --> 00:01:15,650
Hivyo HTML inaruhusu sisi kufungua na kufunga
tag wakati huo huo, tu kwa

27
00:01:15,650 --> 00:01:19,870
ikiwa ni pamoja na kufyeka mbele katika
mwisho kabisa ya kuanza tag, bado

28
00:01:19,870 --> 00:01:21,880
ndani ya mabano angled.

29
00:01:21,880 --> 00:01:24,790
>> Hebu sasa ila faili hili, mabadiliko ya
ruhusa yake, na maoni

30
00:01:24,790 --> 00:01:28,130
ni ndani ya browser -

31
00:01:28,130 --> 00:01:32,460
chmod a + r image.html.

32
00:01:32,460 --> 00:01:42,090
Hebu sasa kufungua Chrome na ziara
http://localhost/image.html.

33
00:01:42,090 --> 00:01:43,630
picha kuvunjwa icon -

34
00:01:43,630 --> 00:01:45,020
sasa, kwa nini huenda kuwa ni nani?

35
00:01:45,020 --> 00:01:48,330
>> Naam, hebu tuangalie amri
line katika kama mimi kwa kweli kuweka hii

36
00:01:48,330 --> 00:01:50,750
faili katika orodha ya umma.

37
00:01:50,750 --> 00:01:55,960
Hebu kwenda nyuma ya gedit, katika
terminal dirisha, na kufanya ls-l.

38
00:01:55,960 --> 00:01:57,110
Na kuna cat.jpg.

39
00:01:57,110 --> 00:01:58,790
>> Lakini angalia ruhusa faili.

40
00:01:58,790 --> 00:02:02,410
Inaonekana kuwa kesi hiyo tu mimi,
mmiliki, unaweza kusoma na kuandika hii

41
00:02:02,410 --> 00:02:03,460
JPEG kwa sasa.

42
00:02:03,460 --> 00:02:05,810
Tunahitaji vile vile kutoa ruhusa
kwa dunia nzima kwa

43
00:02:05,810 --> 00:02:07,350
hii JPEG siku pia.

44
00:02:07,350 --> 00:02:08,259
>> Si tatizo -

45
00:02:08,259 --> 00:02:12,460
chmod a + r cat.jpg.

46
00:02:12,460 --> 00:02:15,820
Hebu kuthibitisha kwamba hiyo ni sahihi
na mwingine ls-l.

47
00:02:15,820 --> 00:02:21,350
Na hakika sasa, wote cat.jpg na
image.html kusoma ruhusa kwa ajili ya

48
00:02:21,350 --> 00:02:22,310
dunia nzima.

49
00:02:22,310 --> 00:02:24,010
>> Hebu sasa kwenda nyuma ya browser.

50
00:02:24,010 --> 00:02:28,560
Hebu bonyeza Reload au Kudhibiti-R. Na
Kuna ni kweli, paka grumpy.

51
00:02:28,560 --> 00:02:31,019
