blogger有奇怪的空格問題

剛剛發現...應該是blogger的bug吧...

當你在建立或修改文章時
每行文字開頭如果是空白
在切換 修改Html 和 撰寫 後,前頭的空白會自動少一個
少到最後就沒有空白了
但是如果開頭有tag,則不會有這個狀況發生...

例如以下的html

你切換個幾次 修改Html 和 撰寫 就會變成

前面的空白就不見了

這樣就不會


I'm having spacing issues in my posts
http://groups.google.com/group/blogger-help-publishing/browse_thread/thread/3c7094c3f16842c4
I have had a similar space problem.

While editing the blog, there's two tab named "modify html" and
"write"(I use the Chinese interface, so I'm not sure the exact name of
this two tab)

Whenever there are lines leading with spaces (spaces at the beginning
of the line), switching between the two tab would remove one leading
space of these lines, until no space at the beginning of the line.

Why does kernel set the obsolete bit?

For unknown reason, kernel set the obsolete bit in both device control register and device register, and never used.

Device Control Register

[Browser] Cache Viewer

某些網頁的圖被層層javascript包圍就是不讓你點下載,關掉javascript就連圖也看不到 (哪些網頁?? ㄟ~~我現在能舉的例子都會讓本blog變18禁。孩子,等你遇到的時候就知道了)(謎之聲: 越萌的網頁越有機會)。針對這種 症頭,最簡單的解決方式就是從cache裡抓

用 IECacheView 檢視所有快取檔案 (Mozilla, Opera 和 Chrome 也有對應版本)
http://blog.joaoko.net/archives/945
IE的沒什麼大問題,因為它的Cache就是在某個目錄下,我的W2k是在C:\Documents and Settings\user\Local Settings\Temporary Internet Files,直接就是原來的檔案改個名字,直接去那個目錄直接看也行

MozillaCacheView v1.16 - View the cache files of Mozilla/Firefox browsers
http://www.nirsoft.net/utils/mozilla_cache_viewer.html
可能是因為firefox的Cache還多了一層index的關係,所以在index還沒寫入map檔的時候,cache viewer會讀到不正確的index
實際使用時常有有缺少檔案,或Cache都產生也看到了,開cache viewer也看不到或是只看的到部份,使用時最好把firefox關掉,以強迫index寫入檔案,再開cache viewer,會比較沒問題

地道的 Firefox 下載ニコニコ動画

印度人 的 吃

印度人吃飯的時間都比較晚
午餐大約一點吃
晚餐大約九點吃

吃素 的 印度人
有的人是素的就好...
但是也有人是不吃 蛋 根莖類 如蘿蔔,馬鈴薯 之類的

吃葷 的 印度人
也不是什麼都能吃
大多人只吃雞肉、紅肉(如羊肉)、海鮮
但不吃豬、牛肉

在台灣你吃葷的話很難去避免吃到豬肉
炒菜可能用豬油,吃麵吃飯甚至會加在菜裡的 肉燥

Linux u64

使用u64的變數時需要特別小心,尤其是call-by-value, u64佔8byte, 要是被當成32-bit處理, 參數可就亂了, 到時候怎麼死的都不知道

include/asm-x86/types.h

#ifndef __ASSEMBLY__

typedef u64 dma64_addr_t;
#if defined(CONFIG_X86_64) || defined(CONFIG_HIGHMEM64G)
/* DMA addresses come in 32-bit and 64-bit flavours. */
typedef u64 dma_addr_t;
#else
typedef u32 dma_addr_t;
#endif

#endif /* __ASSEMBLY__ */


怎么给u64赋值?
http://linux.chinaunix.net/bbs/viewthread.php?tid=1035858
0x100000000ULL


Re: __udivdi3 and linux kernel u64 division question [x86]
http://search.luky.org/linux-kernel.2005/msg38382.html

如何处理两个u32相加溢出的问题? 定义了个u64似乎没用
http://www.unixresources.net/linux/clf/program/archive/00/00/60/56/605612.html
http://www.lslnet.com/linux/f/docs1/i38/big5279591.htm
printf("a = %08x %08x\n", a & 0xFFFFFFFF, a >> 32);
參數壓棧有關係的.
若不轉換, %08x %08x 需要 8字節 , a & 0xFFFFFFFF 也是8字節, 印出來的就是 a 的所有 8位.
printf("a = %08x %08x\n", a & 0xFFFFFFFF, 1234567); 的結果 也是 a = e0000001 00000000.
printf("a = %08x %08x\n", (u32)(a & 0xFFFFFFFF), (u32)(a >> 32) ); 才正確.



小问题:用printk如何直接打印出u64类型的大数??
http://topic.csdn.net/t/20041216/11/3650509.html
d,lx,ld,,lu,这几个都是输出32位的
hd,hx,hu,这几个都是输出16位数据的,
hhd,hhx,hhu,这几个都是输出8位的,
lld,ll,llu,llx,这几个都是输出64位的

git ignore
$GIT_DIR/info/exclude: 整個project的ignore設定
.gitignore: 每個目錄(及以下子目錄)的ignore設定


Remote Operation
git clone <remote_src>
git init

git remote add <remote_name> xxx@xxx:/xxx :新增一個remote設定
git push <remote_name> 將local改變"推"到遠端
git push <remote_name> --all :"推"在.git/refs/heads/下所有的東西
git push <remote_name> --mirror : 推"在.git/refs/下所有的東西 which means .git/ref/heads, .git/ref/remotes and .git/refs/tags/

git pull :"拉"(fetch+merge)

git pull -t :只有"拉"tag
git fetch --tags

Local Operation
git add/rm :告訴git哪些檔案要commit,這些檔案會先進入index。這個過程也叫作Staging
git commit -m "xxx" :只commit有add進index的東西

git commit -a -m "xxx" :commit所有曾經commit的檔案中有 被改變被刪除 的檔案 (add+commit)

git log
git log --all

git checkout <SHA1_code> :切換到某次的commit,you are on "no branch" after checkout
git checkout <tag_name> :切換到某個tag,you are on "no branch" after checkout
git checkout <branch_name> :切換到某個branch
git checkout -b <branch_name> :新增某個branch並切換到它上面

git diff
git merge

git reset
git reset --mixed
(--mixed is the default action)
git reset HEAD :把某個檔案移出index(staging)

git reset --hard :把working tree和index全恢復,即回到 原始狀態
git reset --soft :什麼都不動,但"requires them to be in a good order".....到底是要幹嘛用的阿...

(謎之聲: 你快點回去火星吧,地球是很危險滴!!!)

怎麼找出git中有沒有dangling commit?
現在似乎除了看reflog外沒有其他辦法,新版的git會有warning on dangling commit...

<mkl> Is there anyway to check if there is dangling commit in current database?
<mkl> git log --all or gitk --all won't show dangling commit
<Ilari> mkl: You could extract recent such commits from reflogs, but I don't know easy and fast way to cross-reference them with current branches...
<mkl> yes, reflog seems the only way to find the dangling commit, but only if you aware that there is one, and you have to dig into a long log full with hex code.....
<Ilari> mkl: Also, commit followed by checkout moving from something non-symbolic is pretty good indication that something left dangling.
<mkl> yes, but only if you do aware of the situation....
<mkl> and also commit followed by checkout from tag

<charon> mkl: newer git says which branch you committed on, and indicates a dangling commit with [detached HEAD]
<charon> mkl: 72c69ebc035 which is in 1.6.1
<mkl> Thanks charon, Ilari, drizzd, milli, I finally got the problem clearified and fixed....

http://sitaramc.github.com/concepts/detached-head.html

另一個問題..
首先我回到過去的某個commit: git checkout XXXXXXX

結束後我要回到目前最新的commit
可是突然發現....我不知道它的hash codeㄟ....
當然,在我git checkout XXXXXXX時會show原來的hash code...
但是要是不知道的話要怎麼回到最新的commit呢
git log也看不到...
看來是我自己不知道怎麼搞的搞出了奇怪的狀況
最可能的是因為我用git checkout XXX在不同的commit間切換看code後
直接git checkout <SHA1 of newest commit>然後就改code/commit了
這樣的commit是上去了,但不是在branch上,變成所謂的dangling commit

dangling commit
those commits that is not pointed by any branch/HEAD/tag, and neither the ancestor of any commit pointed by any branch/HEAD/tag

而且dangling commit不會被push/fetch/pull to/from remote端。一個不小心,dangling commit就會消失了...

* 可以用git branch顯示目前所在的branch,改code前一定要切到某個branch下才能改;checkout 某個commit或tag 後,git branch會變成(no branch),這時候不要commit
# git branch
* (no branch)
  test


git branch :list所有的branch與目前HEAD所在的branch

git log --all
list 出所有的commit(但是似乎dangling commit不會被list出來)

git reflog
Reflog is a mechanism to record when the tip of branches are updated. This command is to manage the information recorded in it. 它會log所有的 commit和checkout

git branch -D <branch_name>: 刪除branch
git branch -m <branch_name1> <branch_name2>: 改branch name(branch_name1 -> branch_name2)

.git/HEAD: 目前的指向的位置
.git/refs/heads/<branch_name>: branch "branch_name"指向的位置
.git/refs/tags/<tag_name>: tag "tag_name"指向的位置

git cherry-pick <SHA1_code> :apply某個commit
git merge <branch_name> :與某個branch merge,或者說,apply某個branch的改變

gitk
gitk --all :顯示所有的branch(也不會顯示dangling commit)

git gc :garbage collection

不小心刪掉了某個檔案
在svn可以很簡單的svn up就抓回來了...
git該怎麼辦呢?

我想到的辦法是用git diff產生patch再 patch -R....但是我覺得這樣應該是很蠢的
git該有辦法回復吧?
  • git reset --hard
    把所有改變(data/index)回復,不過不能就單個檔案回復
  • git checkout [FILE]
    回復單一檔案data,像svn revert那樣
    但如果檔案的index已經改變則要先恢復index才能用

    但只是git checkout沒給任何檔案不會回復任何檔案
  • http://www.kernel.org/pub/software/scm/git/docs/git-stash.html
    git stash
    git stash list
    git stash apply
    git stash apply stash@{1}
    git stash clear

又..該檔案又被我git rm掉了
雖然還沒有commit...
但是我該怎麼回到原來的狀態呢.....
(任何index的改變)
git reset
git reset -- [filename]
可以回復index的改變,但僅止於index,實際檔案資料則不行

Openmoko's software strategy for the next 6 months

http://lists.openmoko.org/pipermail/community/2008-December/037352.html

---1 current stable image
Our current stable image is called 'Om2008.9', available at http://downloads.openmoko.org/releases/Om2008.9/
We are sometimes cherry-picking fixes into it, but admittedly not as
many as we would like. If someone wants to step up to become stable
maintainer for this image and cherry-pick more fixes into it, please
let me know.
Alternatively, a number of other images are available, Debian, Qt
Extended, Android, FDOM, SHR, etc.
See http://wiki.openmoko.org/wiki/Distributions for a more
comprehensive list.

---2 Mickey's framework milestones
As many people know, the next big thing for Openmoko will be Mickey's
FSO framework around d-bus and Python, and the Paroli telephony UI.
See http://wiki.openmoko.org/wiki/OpenmokoFramework
A few weeks ago, Mickey released milestone 4, available at http://downloads.freesmartphone.org/fso-stable/milestone4.1/
In late January, he plans to come out with milestone 5, in late March
with milestone 6.
See here for a more detailed roadmap: http://trac.freesmartphone.org/roadmap

---3 next major release, Om2009
After the next 2 FSO milestones, Openmoko will fork off a stable
branch, and spend 2-3 months on testing and bug fixing. This will lead
to our next major release, Om2009.
The telephony UI will be Paroli, see http://code.google.com/p/paroli/
The way things are going right now, we will probably have this release
mid-next year.

http://lists.openmoko.org/pipermail/community/2008-November/035922.html
1. fso-console-image: minimal system with frameworkd, no user interface manager.
2. fso-illume-image: everything in console-image plus X-Window, plus
Enlightenment plus Illume window manager.
3. fso-image: everything in illume-image plus Zhone. Can be used for phone
calls. Like previous milestones. But Zhone is going to be faded out.

To change this default ringtone :

1. copy the sound file into /usr/share/sounds/
2. edit the "ring-tone" field to match your sound filename.

中文化 on OM & Qt

http://www.openmobilefree.net/index.php?entry=entry081205-171449

Qt的中文其實跟我之前的結果差不多
簡訊的中文就可以看到了,但是電話簿的卻看不到(亂碼)
mplayer在play list時看的到,但是在播放中的仍是亂碼
我想可能是程式有特別指定導致的,可能得改程式才有解(?)

  1. Copy font file to /opt/Trolltech/Qtopia/lib/fonts
  2. echo "simsun simsun.ttf FT n 50 0 su" >> /opt/Trolltech/Qtopia/lib/fonts
    (注意寫入的內容與使用的字型相關)
    (我之前是沒有做這一步啦,不過結果似乎一樣)


OM的部份則很成功,簡訊和電話簿中都可以看到中文了
  1. Copy font file to /usr/share/fonts/truetype/
  2. set Openmoko LANG
    echo "export LANG=zh_CN.UTF-8" >> /usr/bin/x-window-manager
  3. Edit /usr/share/applications/*.desktop
    [Desktop Entry]
    Name=Application Manager
    Name[zh_CN]=程序管理
    Comment=Update, install and remove applications
    Encoding=UTF-8

(以上zh_CN應改為zh_TW)



http://wiki.debian.org.hk/w/Make_Debian_support_Chinese
http://www.linuxsir.org/bbs/lastpostinthread315838.html
zh_CN
zh_TW
zh_HK
这些不关编码的事
编码需要在后面指定
比如zh_CN.GB2312 zh_CN.UTF-8 zh_HK.UTF-8

Bleeding edge

[Wiki] Bleeding edge
http://en.wikipedia.org/wiki/Bleeding_edge

什麼是bleeding edge呢?
http://tw.knowledge.yahoo.com/question/question?qid=1306031309229

bleeding edge 是一個新名詞,是從 leading edge / cutting edge (最尖端) 這個詞變化過來的,至於為什麼會用 "bleeding" (流血/犧牲)呢?

用bleeding表達了這產品實在是太新了,所以擁有它是要付出(犧牲)代價的,哪些代價呢? 可能是產品穩定性還不夠(所以你成了新科技的白老鼠??),也可能是產品賣的是天價(所以你成了凱子??),所以說,這真的是 "bleeding edge"啊。

PAE in 8.10 desktop?
http://ubuntuforums.org/showthread.php?t=957430
The server kernel has been compiled with PAE (which solves the problem) and with Xen related things. The latter prevents the installation and use of the NVidia proprietary drivers. Depending on your configuration, this may create another problem, which can be solved by compiling your own kernel, with PAE but without Xen support.

32 bit Ubuntu with 4GB+ of memory
http://ubuntuforums.org/showthread.php?t=855511

RAM >=4G requires to enable PAE
nVidia driver cannot work with Xen enabled

Ubuntu desktop have PAE and Xen disabled
Ubuntu server have both PAE and Xen enabled

but why Ubuntu desktop installation would failed? (unknown)

Solutions
  1. Remove RAM to size < 3GB, install ubuntu desktop, rebuild kernel to enable PAE, re-insert RAM
    (Ubuntu could reboot with 8GB RAM installed and w/o PAE enabled, but there is only 3292MB RAM available, shown on htop, while w/ PAE,8106MB.

    Besides, enabling nVidia accelerated graphics driver w/o PAE enabled w/ 8GB RAM installed, error like the following might be seen while restarting:
    Ubuntu is running in low-graphics mode
    The following error was encountered. You may need to update your configuration to solve this.
    (EE) NVIDIA(0): Failed to load the NVIDIA kernel module!
    (EE) NVIDIA(0): *** Aborting ***
    (EE) Screen(s) found, but none have a usable configuration.

  2. Install ubuntu server, rebuild kernel to disable Xen.

我的寶貝 寶貝
給你一點甜甜,讓你今夜都好眠
我的小鬼 小鬼

嘩啦啦啦啦啦我的寶貝,倦的時候有個人陪
唉呀呀呀呀呀我的寶貝,要你知道你最美

嘩啦啦啦啦啦 我的寶貝
孤單時有人把你想念
唉呀呀呀呀呀 我的寶貝
要你知道你最美

Begining Python: From Novice to Professional

Install
http://www.python.org/download/
http://www.python.org/download/windows/
http://www.python.org/ftp/python/3.0/python-3.0.msi

Types
int,long,float

+,-,*,%,
/
before python3.0,
int use floor round, or use
from __future__ import division
to get float result from int division


// int division
** exponentiation


Hexadecimals: 0xXXXX

Octals:0XXXX(python3.0不會動...)

Container: sequence, mapping

Sequences: list, tuple, string, unicode string, buffer object, xrange object

List
index from 0

Sequence addition
>>> [1,2,3]+[4,5,6]
[1, 2, 3, 4, 5, 6]

Sequence multiplication
>>> [42]*5
[42, 42, 42, 42, 42]

Slicing
>>> xxx=[1,2,3,4,5,6,7,8,9,0]
>>> xxx[4:6]
[5, 6]

>>> xxx[-3:]
[8, 9, 0]
>>> xxx[:]
[1, 2, 3, 4, 5, 6, 7, 8, 9, 0]
>>> xxx[5:-3]
[6, 7]
>>> xxx[:2]
[1, 2]

Step
>>> xxx[::2]
[1, 3, 5, 7, 9]
>>> xxx[1::2]
[2, 4, 6, 8, 0]

keywork None
>>> xxx=[None]
>>> xxx
[None]

>>> len(x)
0
>>> len(xxx)
10
>>> max(xxx)
9
>>> min(xxx)
0

Sequence deletion
>>> del(xx[3])
>>> xx
['h', 'e', 'l', 'o']

Item Assignment
>>> xx
['h', 'e', 'l', 'l', 'o']
>>> xx[2]="a"
>>> xx
['h', 'e', 'a', 'l', 'o']

Slice Assignment
>>> xx[2:]=list("llo")
>>> xx
['h', 'e', 'l', 'l', 'o']

Convert to list
>>> list("hello")
['h', 'e', 'l', 'l', 'o']

string is not changable, like tuple.
>>> x="hello"
>>> x[3]="a"
Traceback (most recent call last):
File "<pyshell#34>", line 1, in <module>
x[3]="a"
TypeError: 'str' object does not support item assignment
>>> xx=list(x)
>>> xx[3]="a"
>>> xx
['h', 'e', 'l', 'a', 'o']

Membership check -- in
>>> xxx=[1,2,3,4,5,6,7,8,9,0]
>>> 3 in xxx
True
>>> 10 in xxx
False

List methods - object.method(argument)
append(value)
count(value) - count the occurances of the given value
extend(list_object)
index(value) - find the index of the given value
insert(pos,value)
pop(pos) - remove the element of the given position, the last one if pos not given
remove(value)
reverse()
sort()
sort(cmp)
sort(key=len)
sort(reverse=True|False)


Tuple
>>> 1
1
>>> 1,
(1,)
>>> (1,)
(1,)
>>> (1)
1

Convert list to tuple
>>> tuple([1,2,3])
(1, 2, 3)
>>>


Strings
single quote '
double quote "
escape \

String Concatenation +
String representations
str(x)
repr(x) or backticks `x`

Long string """ or '''
Raw string r"xxx"
Unicode string u"xxx"


Dictionary
>>> xx={'x':1,'y':2,'z':3}
>>> xx['y']
2
>>> dict([('name','alice'),('age',22)])
{'age': 22, 'name': 'alice'}
>>> dict(name='ann',age=27)
{'age': 27, 'name': 'ann'}


>>> xx=dict(name='ann',age=27)
>>> 'name' in xx
True
>>> 'ann' in xx
False

a solution to the echo issue

just a note, haven't tried it, been a little lazy recently....


http://lists.openmoko.org/nabble.html#nabble-td1486414|a1518726
In file /usr/lib/python2.5/site-packages/framework/subsystems/ogsmd/modems/ti_calypso/unsolicited.py, function percentCPI, line 210 aprox

Where it says:
info = {}


I have:
devchannel = self._object.modem.communicationChannel("DeviceMediator")
devchannel.enqueue( "%N0187" )
info = {}

希望
作詞:李宗盛 作曲:李宗盛

養幾個孩子是我人生的願望 我喜歡他們圍繞在我身旁
如果這紛亂的世界讓我沮喪 我就去看看他們眼中的光芒

總有一天我會越來越忙 還好孩子總是給我希望
看著他們一天一天成長 我真的忍不住要把夢想對他講

總在他們的身上 看到自己過去的模樣
對自己、對人生、對未來的渴望

他們是我的希望 讓我有繼續的力量
他們是未來的希望 所有的孩子都一樣
他們是未來的希望 但願我能給他一個最像天堂的地方

依稀記得他們出生時的模樣 我和太太眼裡泛著淚光
雖然他長得和我不是很像 但是朋友都說他比我漂亮

毫無意外我真的越來越忙 還好孩子總是給我希望
如果能夠陪著他們一起成長 生命裡就算失去一些別的又怎麼樣

總在他們的身上 看到自己過去的模樣
對自己、對人生、對未來的渴望

他們是我的希望 讓我有繼續的力量
他們是未來的希望 所有的孩子都一樣
他們是未來的希望 但願我能給他一個最像天堂的地方

雖然我難免還是會想 這樣的歌很少人會欣賞
這一首歌無關兒女情長 只獻給我家那三個可愛的姑娘
他們在我心裡最柔軟的地方 雖然我總是身在遠方
我生命裡美好的一切願與他們分享
