这两天在看一些JS代码,TMD的,长长一大段,且没有一点格式,真不知这些人是为什么要这样搞,想不易让人看懂还是喜欢这种风格.看得头都大

好在今晚找到个格式化工具,爽就一个字

http://www.51099.com/tool/js-format-compress.html 格式化及压缩

http://www.51099.com/tool/js-format-color.html  可以格式化javascript代码 并在格式化的同时对代码进行着色

一、cygwin是什么？
 简而言之，cygwin是一个在windows平台上运行的 linux模拟环境，是cygnus solutions公司开发的自由软件

Screen 这个东东真的够酷、好玩、十二分地有意思，而且也是相当地实用。Screen 就像一个 Shell 孵化器，只需一个 Shell，在 Screen 的神奇作用下，“道生一，一生二，二生三，三生万物”，想要多少个 Shell 都可以。当然，前提是只要你愿意。有了 Screen，再也不需要同时打开多个终端或者多个标签页了。还有更加好玩的在后头，在 Screen 孵化的 Shell 中执行任务，即便是你退出终端，仍然不会对它造成任何影响。稍后，同样可以再次进入 Screen 的世界。

如果你从来没有安装过 Screen，那么就执行 sudo apt-get install screen 吧。然后，在终端中输入 screen 就启动 Screen 了。按照提示按空格键或回车键开始我们的 Screen 快乐之旅吧。现在，你可以随便执行某些命令来测试，如：ls -l。接着，我们就用 Screen 来孵化一个新的 Shell，同时按组合键 ctrl-a c，同样的，你能够在这里执行命令，我们假如是 ps aux。加上最初的，那么现在在 Screen 中就有两个 Shell 了。可是，如何在这两个 Shell 间切换呢？试试 ctrl-a ctrl-a 看？是不是很方便地切换回来了呢。假如你要退出，甚至关掉终端，那么好吧，按 ctrl-a ctrl-d，屏幕会显示 [detached]，你就放心的关终端吧。是的，在玩了一圈之后，你又想进入 Screen 了，怎么办？只需输入 screen -d -r 即可。

以下总结一些常用的 Screen 操作快捷键，供大家参考：

ctrl-a c：创建一个新的 Shell
ctrl-a ctrl-a：在 Shell 间切换
ctrl-a n：切换到下一个 Shell
ctrl-a p：切换到上一个 Shell
ctrl-a 0...9：同样是切换各个 Shell
ctrl-a d：退出 Screen 会话

Error: No Package Matching glibc.i686

出现Error: No Package Matching glibc.i686的问题解决办法
yum install glibc glibc.i386 --enablerepo=c532*

再yum install gcc
就OK了

c++,g++
yum install gcc-c++

在configure 加上 --without-zlib 可以编译通过

++
--with-libxml2-dir=/usr/local/libxml2

cd zlib-1.2.3 //进入zlib目录

make
make installmake clean
