[Work] Using vim

Three modes

[normal] Esc
[insert] i, I
[visual] v, C+v (visual block)

Basic commands

:w        write out
:q        quit
:q!       force quit
ZZ        write the file and quit
dd        delete one line
3dd       delete three lines
D         delete portion of current line to right of the cursor
p         paste
u         undo
C+r       redo

w         move cursor one word to right
b         move cursor one word to left
0         move cursor to beginning of line
$         move cursor to end of line
nG        move cursor to line n
C+f       scroll forward one screen
C+b       scroll backward one screen
a         append to right of current cursor position (end with ESC)
dw        delete current word (end with ESC)
ma        mark currrent position
d`a       delete everything from the marked position to here
`a        go back to the marked position
/string   search forward for string (end with Enter)
n         repeat the last search (``next search'')
:s/s1/s2  replace (``substitute'') (the first) s1 in this line by s2
:%s/s1/s2 replace (``substitute'') (the first) s1 by s2 in filewide
%         go to the "mate," if one exists, of this parenthesis
          or brace or bracket (very useful for programmers!)

Advanced commands

:syntax on     syntax coloring
move cursor to the defination of a function(variable): 1. ma 2. gD

visual block operations:
1. C+v -- swicth to visual block mode
2. select rectangular region
3. I -- switch to insert mode and do editing in the selected region, e.g. put  "//" there
4. Esc -- back to the normal mode
5. you can also delete a rectangle region by hit "d" 

Customize your vim

put ~.vimrc
e.g.

set visualbell            " Silence the bell, use a flash instead
set cinoptions=:.5s,>1s,p0,t0,(0,g2         " :.5s = indent case statements 1/2 shiftwidth
             " >1s = indent 1 shiftwidth

             " t0 = indent function return type 0 spaces
             " (0 = indent from unclosed parantheses
             " g2 = indent C++ scope resolution 2 spaces
set cinwords=if,else,while,do,for,switch,case " Which keywords should indent

                                                " o,r=autoinsert comment leader
set cindent            " indent on cinwords
set shiftwidth=2                  " set shiftwidth to 4 spaces
set tabstop=2                   " set tab to 4 spaces
set showmatch                   " Show matching brackets/braces/parantheses.
"set background=dark                          " set background to dark
set showcmd            " Show (partial) command in status line.
set autowrite                   " Automatically  save before commands like :next and :make
set textwidth=98                  " My terminal is 98 characters wide

30岁的生日

30岁了
还是个学生
还要很久才能毕业的学生
觉得很老
觉得生活很没盼头

30岁的那天
妻子做了一根生日面和一盒 生日巧克力




妻子总说我很老了
不再是和我一个时代的
因为我是P4 (喜欢谐音的我想起“奔死”， 但“甭死”)
而她是P3
其实人的年老不光是因为身体的自然老化
很大一部分是周围的人不再把你当成年轻人了
就像说多了谣言也会兑现
比如你老说两个人要分手
结果最后可能真分手

所以家长很少说自己的孩子长大以后会一无是处
虽然有的父母说自己的孩子活脱是个强盗魔鬼
但心里肯定向着所有的名人都有不安份的童年

看看每个下台以后首脑
你会发现顿时老了10几岁
比如克林顿
甚至连竞选失败的John Kerry
也瞬间变成了一个老人

还比如
你可以说一个小孩长得真快
你也可以说一个小孩长得真老
但你不可以说一个耄耋老人他/她真老
这好比说她/他怎么这么老了还活着

说到底
给人以自信
给自己以自信
活地乐观点
也就会年轻点

战斗着
工作着
运动着
思想着
人也会更年轻

多给旁边的人鼓励哦 ！

Graphics in LaTeX

To use graphics in LaTeX, you must include the graphicx package using the declaration below. You should put it after the \documentclass declaration.

    \usepackage{graphicx}

If you need a graphic or tabular material to be part of the text, you can just put it inline. It will not have a caption or any fancy formatting.

    \includegraphics{subdivision}

If you need it to appear in the list of figures or tables, it should be placed in the floating environment.

    \begin{figure}[h]
\caption{A Figure}
\centering
% DO NOT ADD A FILENAME EXTENSION TO THE GRAPHIC FILE
\includegraphics{subdivision}
\label{subd}
\end{figure}

Positioning Graphics

You can control the position of the figure on the page or within the chapter by including letters between the brackets after the \begin{figure} declarations. The options are h = right here, t = top of the page, b = bottom of the page, and p = separate page of figures. You can also place the letters in order of your preference and you can add an exclamation mark to make it try hard. An example of this is: \begin{figure}[h!tbp]. With this example, LaTeX will try REALLY hard to place it at that exact point in the text. If that does not work, it will place it at the top of the next page. If that also does not work, it will attempt to place it at the bottom of the page. The last resort will be placing it on a separate page (even if it will not take up a whole page) right before the start of a new chapter or section. Rotating and Scaling Graphics

You can also do some minor editing to your figures in LaTeX. The following example shows how you can rotate and scale your graphic:

    \section{More Figure Stuff}
\begin{figure}[h!]
\caption{A Smaller Figure, Flipped Upside Down}
\centering
% DO NOT ADD A FILENAME EXTENSION TO THE GRAPHIC FILE
\includegraphics[scale=0.5,angle=180]{subdivision}
\label{subd2}
\end{figure}
\section{Even More Yet Figure Stuff}

Remember, the angle must be in degrees without any unit information. Scaling does not use percentages but decimals. If you divide the percentage you want by 100, you will get the decimal value to use. One will keep the image the original size. Cropping With some clever work you can crop a figure, which is handy if (for instance) your EPS or PDF is a little graphic on a whole sheet of paper. The viewport arguments are the lower-left and upper-right coordinates for the area you want to crop.

    \begin{figure}[h!]
\caption{A Cropped Figure}
\centering
% DO NOT ADD A FILENAME EXTENSION TO THE GRAPHIC FILE
\includegraphics[clip=true, viewport=.0in .0in 1in 1in]{subdivision}
\label{subd3}
\end{figure}

Ten Most Common Mistakes in Math Theses

1. To typeset {a | a>0}, try $\{a\mid a>0\}$. The point is to use \mid instead of |. The latter has spacing problems.
2. To typeset f: X -> Y, try $f\colon X\to Y$. Use \colon instead of : to get the correct spacing.
3. Consider typing "there exists" instead of "\exists" and "for all" instead of "\forall". They take about the same amount of typing, and it's often easier on the reader.
4. After a period, TeX adds space. To remove that space, include "\ ", a backslash followed by a blank space. For example: "Dr. No" should be written "Dr.\ No" and "i.e." should be written "i.e.\ ".
5. To typeset the variable x, remember the dollar signs: $x$.
6. To typeset cos, log, etc., use \cos, \log, etc. Use \operatorname to define your own "math operators". For example, \newcommand{\span}{\operatorname{span}} causes \span to act like \cos. Both the font and spacing are modified.
7. Know the difference between - (hyphen, used to hyphenate words), -- (en dash, used for ranges, e.g., 1--10), and --- (em dash, used for parenthetical phrases).
8. Use a ~ to avoid bad linebreaks. Example: Joe Shmoe~\cite{schmoe} or Theorem~\ref{myTheorem}. (Learn to use labels and refs, by the way.) You should also use ~ to avoid having a linebreak that causes the next line to begin with a number.
9. $\int_0^1x\,dx$ is better than $\int_0^1x dx$. The \, adds a bit of space.
10. Maybe nine is enough, for now.

IE/Firefox automatically close
why did IE/Firefox automatically close when we I browsing some webpage(e.g. the webpage with Bezier curve demo.)?
The solution:
The reason of that problem is the MS Java runtime is out of order. (probably because the counter in the virtual machine) So just go to Sun's Java webpage and download the newest Java Runtime Environment and replace the old one on my computer.
But I did it in a different way. I just went to Control panel and then Add/Remove programs. There is one item call J2SE Runtime Environment 5.0 Update 6.0. I clicked "change" and then follow the installation windows. After this update, my web browser can stably browse interactive web pages.

一部一部的看韩剧

骨子里很喜欢一笔一划的中文字
内心里觉得说中国话很亲切

工作中的英语
和代码中的符号和数字
让我的神经变得麻木

人麻木了
有两种后果
一种是变傻了
一种是变累了

人累了有两种出路
休息和生病

累了的我
最简单的想法是
我要
看中文电视
听中文广播
读中文小说

最被动的方法是看电视
但身边中文电视很少
韩国电视到不少
很多中国朋友
或有韩国朋友的中国朋友
他们读喜欢看韩剧

所以借了很多的韩剧
《浪漫满屋》
《雏菊》
《冬季恋歌》
《恋爱时代》
《我的女孩》
《野蛮女友》
《真的真的喜欢你》
《嫂嫂19岁》
《宫》
《宫s》
《大长今》
......

我喜欢看长篇的连续剧
喜欢一口气看完一部电视
看到凌晨的时候
困了累了饿了
心理防线也弱了
剧情渐渐的推向高潮
情感的积累也越来越厚重

于是主人公的一句不经意的话
或者一个平凡的场景
可能触发我感情的爆发
经常夜深人静中的我
痛哭流涕
像个孩子

经常在这样的时候
我觉得我还活着
我还年轻
我还有情感
我还在感念生活

这也是人老了的重要标志
年轻人很少回忆
年轻人很少感触
年轻人会因为受欺负而哭泣
年轻人会因为失恋而痛不欲生

而老人不同
老人会因为吃到了儿时的一种特殊的东西而流泪
老人会想起几十年前牵着自己的小手走过田头的妈妈而浮现甜蜜的笑容
老人会因为想起初恋而老泪纵横

简单的生活故事，每一天的叙述

不知道什么叫blog
只是听别人说得很多
很多人花了很多时间在做我不知道的事情
很奇怪， 很不理解

我的妻子也每天在做这样的事情
我没看过也没关心过

学了12年的计算机专业
有点荒唐

今天工作累了
想休息一下
看中文听中文
对我来说就是最大的休息

看了看几部中文电影
觉得无趣

心不在焉的浏览着蚂蚁大小的新闻条目
看见了俞敏洪的一篇 “ 对生命的态度 ”
在他的说法里
生活的快乐来得很轻快，轻松快捷
途经很简单
乐观点
看好的地方

就是说娶了丑老婆
不要看脸上的疤
要看心里的德
如果两个都没得看
就看在给你生了个胖娃娃
即使你刨根究底说一个个都不行
我也不相信世界上有完缺的人

其实这生活观
所有人都知道
但现实生活中大多数人烦恼
大部分时间烦恼

但俞敏洪就是能把越是不敏感的人变得容易激动

我问妻子“弗哌酸”是什么药
妻子好奇问我为什么问
我说那是俞敏洪在夏威夷拉肚子吃得药

妻子知道我在看blog
很好奇也很兴奋

当场要我开个账号
我说再等等
今天就算了

继续看俞老师的blog
看起来很遥远
10年前看这些东西会激动
会做梦
往前做梦，或叫憧憬

现在看这些东西
多少有点麻木
但也会觉得好笑
也会做梦
往后做梦， 这叫追忆

追忆逝水的年华
会染上一些水彩
朦朦胧胧
却又能激起内心的涟漪
清清的荡漾
暂时忘却现实的刻薄

心，情
都是飘摇不定的
捉摸不透的
在一瞬间
你可能会爱上一个人
而且这个爱可能被你一辈子不能忘记
这叫一见钟情

忽然间想起什么
不是褪色的爱
而是儿时的爱好
我很喜欢写
描绘我的生活
勾画我的情感

所以决定今天上路
