吓？只是一句對不起？
單憑別人的一句對不起，你會服氣嗎？
你們的監督，打算用這種如廢物一樣的道歉方式來負責任，
哼，一把年紀，連負責任的方法也不懂嗎？
所謂的負責任 就是要有痛苦的感覺
因為自己的緣故為別人帶來麻煩，所以自己也要去承受那份痛楚
弄壞別人的銀器餐具，就要買金器餐具作為賠償
散播惡臭的工廠的社長，就要住在那個工廠的煙旁
就這是負責任
可是這世上那些所謂的高層人仕，總是不想嚐到苦果。
稍有差池，就隨便低頭認錯，一句對不起，以為這樣就可以完事。

container_of, offsetof
#define offsetof(TYPE, MEMBER) ((size_t) &((TYPE *)0)->MEMBER)
/**
* container_of - cast a member of a structure out to the containing structure
* @ptr: the pointer to the member.
* @type: the type of the container struct this is embedded in.
* @member: the name of the member within the struct.
*
*/
#define container_of(ptr, type, member) ({ \
const typeof( ((type *)0)->member ) *__mptr = (ptr); \
(type *)( (char *)__mptr - offsetof(type,member) );})
This marco is very useful, it will find a pointer pointing to the containner address.
I just use it for a long time, but don't know how it works, today I am going to check it out.
The first line find a pointer __mptr pointer to the member,
second line use __mptr to substract the offset the member's offset in the container.
I like the following trick,
((TYPE *)0)->MEMBER
Cast a '0' to the containter structure pointer,
->MEMBER , will give the offset accordingly.
The marco are inside kernel.h and stddef.h

color the shell
Put this in the home directory ~/.bashrc
# enable color support of ls and also add handy aliases
if [ "$TERM" != "dumb" ]; then
[ -e "$HOME/.dircolors" ] && DIR_COLORS="$HOME/.dircolors"
[ -e "$DIR_COLORS" ] || DIR_COLORS=""
eval "`dircolors -b $DIR_COLORS`"
alias ls='ls --color=auto'
fi
Create a file .dircolors to include the following, where I have to set
DIR 07;31;47, which means, reverse, background color is red, text color is white.
Then it is easy to differenate a directory or normal file.
# Configuration file for dircolors, a utility to help you set the
# LS_COLORS environment variable used by GNU ls with the --color option.
# The keywords COLOR, OPTIONS, and EIGHTBIT (honored by the
# slackware version of dircolors) are recognized but ignored.

VIM , ctags and supertab
唔知大家用咩editor去寫programme,ultraedit?source insight?呢d都係要俾錢，雖然有得crack,但係唔好用，唔夠快！小弟數年前有人介紹vim我用，個位人兄就係mike少，唔知佢仲有無用或者仲係未好懶咁用呢..哈哈.....我都懶用嫁，只不過好既plugin就一定要用！咁0岩轉工都要執下，順便係度介紹下啦！
plugin:
bufexplorer.vim
getscriptPlugin.vim
gzip.vim
matchparen.vim
minibufexpl.vim
netrwPlugin.vim
rrhelper.vim
ShowFunc.vim
spellfile.vim
supertab.vim
taglist.vim
tarPlugin.vim
themes.vim
tohtml.vim
vimballPlugin.vim
zipPlugin.vim
當中taglist.vim 同supertab.vim 好用到不得了。
taglist.vim 跟ctags 一起用，裝好ctags,
$ ctags -R ./
把cursor移到variable,function,marco name,按下
'ctrl'+']'
就會跳去declartion
'ctrl'+'t'
就會返回。
supertab.vim
只要按一下'tab',就會自動幫你完成長長的variable/function/marco name.....
就好似係shell 按'tab'完成file名 一樣..真係好正呀！@0@
常用command
:Tlist
:set fileformat=unix
:WMToggle
ctrl+w s
最喜愛的color scheme
