由于Zend Optimizer的支持把ubuntu10.04下的php5.3降级到php5.2
因为Zend Optimizer 3.3.9都还没有开始支持php5.3，所以把ubuntu10.4的php5.3降级到php5.2
步骤
１ 增加karmic源
njava@njava.com:~$sudo vi /etc/apt/sources.list.d/karmic.list deb http://archive.ubuntu.com/ubuntu/ karmic main restricted universe multiverse deb-src http://archive.ubuntu.com/ubuntu/ karmic main restricted universe multiverse deb http://archive.ubuntu.com/ubuntu/ karmic-updates main restricted universe multiverse deb-src http://archive.ubuntu.com/ubuntu/ karmic-updates main restricted universe multiverse deb http://security.ubuntu.com/ubuntu karmic-security main restricted universe multiverse deb-src http://security.ubuntu.com/ubuntu karmic-security main restricted universe multiverse
在Ubuntu 10.04 下安装Ispcp管理虚拟主机
一时大意，在服务器上装了ubuntu10.04,由于太新了，ispcp最新版本ispCP Omega 1.0.6 • 2010-08-04都不能直接安装，所以从svn check了最新的代码来安装
1. check ispCP
njava@njava.com:~$svn checkout http://www.isp-control.net:800/ispcp_svn/trunk/
2. update相关组件,监测安装脚本, 在ubuntu 10.04下将识别出ubuntu-packages-lucid的脚本
njava@njava.com:~$cd trunk njava@njava.com:~$aptitude update && aptitude safe-upgrade njava@njava.com:~$aptitude install $(cat ./docs/Ubuntu/ubuntu-packages-`lsb_release -cs`)
在PhpStorm中使用Xdebug来调试php断点
用PhpStorm有几个月的时间了，一直没找到一种好的调试断点的方法，今天突然看到这个东西，不错，记录下来
1 从http://code.activestate.com/komodo/remotedebugging/下载mac版本的Komodo-PHPRemoteDebugging-6.0.0-beta3-54627-macosx.tar.gz
2 提取相应php版本的xdebug.so
3 丢到 /usr/local/php5/lib/php/extensions/no-debug-non-zts-20090626/ 下面
4 在 /usr/local/php5/lib/php.ini里添加配置文件
[xdebug] zend_extension=/usr/local/php5/lib/php/extensions/no-debug-non-zts-20090626/xdebug.so xdebug.idekey=PhpStorm1 xdebug.remote_enable=On xdebug.remote_host=localhost xdebug.remote_port=9000 xdebug.remote_handler=dbgp
5 重启apache
6 配置PhpStorm ，ok

python爬虫和数据挖掘
考虑用python做爬虫，需要研究学习的python模块
1内置的 urllib, urllib2 库用来爬取数据
2 使用BeautifulSoup做数据清洗
http://www.crummy.com/software/BeautifulSoup/
编码规则
Beautiful Soup tries the following encodings, in order of priority, to turn your document into Unicode:
1 An encoding you pass in as the fromEncoding argument to the soup constructor.
2 An encoding discovered in the document itself: for instance, in an XML declaration or (for HTML documents) an http-equiv META tag. If Beautiful Soup finds this kind of encoding within the document, it parses the document again from the beginning and gives the new encoding a try. The only exception is if you explicitly specified an encoding, and that encoding actually worked: then it will ignore any encoding it finds in the document.
3 An encoding sniffed by looking at the first few bytes of the file. If an encoding is detected at this stage, it will be one of the UTF-* encodings, EBCDIC, or ASCII.
4 An encoding sniffed by the chardet library, if you have it installed.
5 UTF-8
6 Windows-1252
可以用fromEncoding参数来构造BeautifulSoup
soup = BeautifulSoup(euc_jp, fromEncoding="gbk")
3 使用python chardet 字符编码判断

迅速修复nginx fcgi方式配置漏洞
2010年5月20日，80后爆nginx 0day漏洞，上传图片可入侵100万服务器。目前已经有好几个大型互联网公司被入侵了，公司类型包括电子商务、游戏、SNS等。
现在看来，这个漏洞不属于Nginx的漏洞. 是配置的问题, 现在到处都在说是Nginx的Bug,关闭fix_pathinfo(默认是开启的).就可以解决
临时修复方法如下，可3选其一。
1、设置php.ini的cgi.fix_pathinfo为0，重启php。最方便，但修改设置的影响需要自己评估。
2、给nginx的vhost配置添加如下内容，重启nginx。vhost较少的情况下也很方便。
if ( $fastcgi_script_name ~ \..*\/.*php ) {
return 403;
}
3、禁止上传目录解释PHP程序。不需要动webserver，如果vhost和服务器较多，短期内难度急剧上升；建议在vhost和服务器较少的情况下采用。
初学python的Web框架Django-模板
修改django的url规则和模板的基本操作
We’ll just have to take a few steps to make the conversion. We will:
1. Convert the URLconf.
2. Rename a few templates.
3. Delete some of the old, unneeded views.
4. Fix up URL handling for the new views.
