無咩時間..唯有睇下其他大行既推介價，
瑞信-40
野村-45
摩根大通-35.1
摩根士丹利-29.11
德銀-40.3
平均約$37,最高最低唔要，平均就係$38.
ev 雖然+11%, 約10蚊，現價己經係3倍，想係2倍ev既價錢入多幾手，睇怕無咩可能。
但係2倍ev個價係要d 天災或者人禍出現先可以有咁低。
雖然3倍ev 唔算好平，但係要記住股價係可以去到5倍ev....

速讀速讀速讀速讀速讀速讀速讀
速讀是必要的技巧！點解？
以1分鐘計，有人只可以讀100隻英文字，有人可以讀800隻。
1個鐘相差700隻，
一日工作8小時，相差5600隻，
一個星期，相差39200隻.....................
大家對數字唔係好敏感，39200即係點？
以小弟來舉例，一份specifcaion有191300字，除以39200係4.88。
如果睇同一份speificaion，兩者就相差了4.88個星期，即係當你好辛苦睇完1份speifcation，
人地睇左5份！
如果以人工計，人地可以出５份糧了．．．或者可以吞ｐｏｐ１個月．．．點都好，時間就係金錢！
以一般學生來講，人地點解可以10個A,你就得6個丫？6個absent喎 = =
你身邊總有d人温得個一陣書, 考試又好鬼死高分（我唔係指我，雖然我係）
點解呢？點解呢？點解呢？
人地唔通一出世就識計數？一出世就識英文？唔係唔係．．．．
因為人地讀野夠快，理解力，記憶力強。
e家就係研究第一步讀野點樣先夠快！
去片先！

仲有個測試，同練習
http://www.rocketreader.com/
我得28x per min..所以都要緊記以下心法，好好練習。
1.專心再專心，唔可以俾人嘈，唔可以聽歌
2.唔可以讀隻字出口，心讀更加唔可以，要記住當你一讀你就慢了
例如: 我係一隻狗，把口正在張開
你讀完呢十一隻字，你得到d咩資料丫？我當你叻,2秒讀完。
但係請你睇下呢幅圖，你一眼就睇完，呢幅圖就等於讀左個11集字。
1眼 同2秒，點比？
3.一望唔係望一隻字，係望幾隻字。 你隻死人眼咁大隻，用來望住一隻字？浪唔浪費d呀？一次望幾隻字絶對唔係問題，你起初可以3,4隻,慣左之後再慢慢加，之後就可以8隻,10隻的了。
4.焦點不可似停，眼要不停咁掃
5.仲有d基本野，例如先睇toc(table of content),睇頭睇尾，其實都係要大家係讀之前大既知道有d咩讀，係未你需要既野。
以1分鐘計，有人只可以讀100隻英文字，有人可以讀800隻。

one out-渡久地東亞
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。
By 渡久地東亞
One Out 可是一套既特別又有趣的漫畫，渡久地東亞地是特別的人物，
作者是甲斐谷忍，同時也是Liar Game的作者。

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

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
