First install Homebrew using command: [1]
ruby -e "$(curl -fsSL https://raw.github.com/mxcl/homebrew/go)"
Then using brew to install gdb using command: [2]

给一个有规律的整数矩阵，每行元素从左到右递增，第列元素从上到下递增。
要求完成一个查找函数，输入为满足以上条件的一个二维数组以及一个整数，判断数组中是否包含此整数。
如：
[tex] \begin{bmatrix} 1 & 2 & 8 & 9 \\ 2 & 4& 9& 12\\ 4 & 7 & 10&13 \\ 6 & 8 & 11& 15\end{bmatrix}[/tex]
查找7应当返回true,查找5应当返回false.
Create a ~/.bash_profile and enable colors using:
export PS1="\[\033[36m\]\u\[\033[m\]@\[\033[32m\]\h:\[\033[33;1m\]\w\[\033[m\]\$" export CLICOLOR=1 # light theme, white background export LSCOLORS=ExFxBxDxCxegedabagacad alias ls='ls -GFh'
In the ~/ folder, create subfolder .bash and drop gitprompt.sh and gitstatus.py files there (bash.zip)
In the ~/.bash_profile file, add ``source ~/.bash/gitprompt.s'' so the file becomes:
export PS1="\[\033[36m\]\u\[\033[m\]@\[\033[32m\]\h:\[\033[33;1m\]\w\[\033[m\]\$" export CLICOLOR=1 # light theme, white background export LSCOLORS=ExFxBxDxCxegedabagacad alias ls='ls -GFh' #enable git bash prompt source ~/.bash/gitprompt.sh
Restart terminal, and see the new look :

1. 下载安装w3m
$ apt-get install w3m $ cvs -d :pserver:anonymous@cvs.namazu.org:/storage/cvsroot co emacs-w3m
下载完成后，将源码拷贝到/usr/local/src目录下
$ sudo cp -r emacs-w3m /usr/local/src/ $ cd /usr/local/src/emacs-w3m/ $ sudo autoconf $ sudo ./configure $ sudo make $ sudo make install
2. Emacs 24.3，在～/.emacs.d/init.el 文件里添加如下设置
;; set emacs-w3m
;;设置emacs-w3m浏览器
(add-to-list 'load-path "/usr/local/src/emacs-w3m/")
(require 'w3m)
(require 'w3m-load)
;(require 'mime-w3m)
;; 设置w3m主页
(setq w3m-home-page "http://www.google.com")
;; 默认显示图片
(setq w3m-default-display-inline-images t)
(setq w3m-default-toggle-inline-images t)
;; 使用cookies
(setq w3m-command-arguments '("-cookie" "-F"))
(setq w3m-use-cookies t)
(setq browse-url-browser-function 'w3m-browse-url)
(setq w3m-view-this-url-new-session-in-background t)
3. 在Emacs中开启w3m:
M-x w3m
