InputStream、byte[] 互转
Mar 31st
InputStream转byte[]
private byte[] getBytesFromInputStream(InputStream is) throws IOException {
ByteArrayOutputStream bytestream = new ByteArrayOutputStream();
int ch;
while ((ch = is.read()) != -1) {
bytestream.write(ch);
}
byte imgdata[] = bytestream.toByteArray();
bytestream.close();
return imgdata;
}
byte[]转InputStream
byte[] data; InputStream is = new ByteArrayInputStream(data);

修复Ubuntu 9.10
Nov 28th
昨晚破解Win7失败，导致又进不来Win7了@_@，修复一下吧。
首先光碟启动Ubuntu，非安装进入Ubuntu下的控制台。
sudo mount /dev/sda6 /mnt //如果要你的/boot是单独分区的话，需要运行以下命令 sudo mount /dev/sda6 /mnt/boot sudo grub-install --root-directory=/mnt/ /dev/sda
进入Ubuntu系统后，在运行以下命令
sudo update-grub sudo grub-install /dev/sda
如果你想修改启动顺序阿，启动默认时间阿，可以修改
/boot/grub/grub.cfg
这个和Grub1的配置文件有点不同，因为Ubuntu 9.10使用的是Grub2了。
2009年度总结
Nov 27th
今年最主要的收获还是关于Linux系统方面的知识。
统计Apache的访问UV
cat /home/app/httpd/logs/access_log|grep 04/Nov/2009 | awk '{print $1}' | sort | uniq -c | sort -rn | wc -l
系统实时并发
tail -10000 /home/app/httpd/logs/access_log | awk '{print $5}' | sort | uniq -c | sort -rn | head
系统连接状态统计
netstat -an | awk '{print $6}' | sort |uniq -c| sort -rn
[译]在Ubuntu或者Debian中安装PCRE库( Perl 5 Compatible Regular Expression Library )

原文地址：
Ubuntu / Debian Install PCRE Library ( Perl 5 Compatible Regular Expression Library )
http://www.cyberciti.biz/faq/debian-ubuntu-linux-install-libpcre3-dev/
I need to compile few application and I need Perl 5 Compatible Regular Expression Library (PCRE). Under CentOS I can use a package called pcre-devel, but Debian do not have the same. How do I install pcre-devel under Debian / Ubuntu Linux?
我需要编译一些应用程序，同时也需要Perl 5 兼容正则表达式库（PCRE）。在CentOs下，我可以使用一个叫pcre-devel，但是Debian可就不一样了。我怎样在Debian/Ubuntu Linux下安装pcre-devel呢？
Perl-compatible regular expression library. PCRE has its own native API, but a set of “wrapper” functions that are based on the POSIX API are also supplied in the library libpcreposix. Note that this just provides a POSIX calling interface to PCRE: the regular expressions themselves still follow Perl syntax and semantics. The header file for the POSIX-style functions is called pcreposix.h. To install PCRE, type thy following command:
Perl兼容正则表达式库（PCRE）有自己原生API，但是这一系列封装函是基于POSIX API，而POSIX API也支持libpcreposix库。这样只要提供一个POSIX的调用接口给PCRE后，正则表达式本身仍遵循Perl的语法和语义。POSIX-style的头文件是pcreposix.h，所以，安装PCRE，需要运行以下命令。
sudo apt-get update sudo apt-get install libpcre3 libpcre3-dev
你可能还需要安装
sudo apt-get install openssl libssl-dev
