[译]在Ubuntu或者Debian中安装PCRE库( Perl 5 Compatible Regular Expression Library )

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

The Road Not Taken
Sep 7th
在李开复的日志里，引用了这样的几句诗，
也许多少年后在某个地方，
我将轻声叹息把往事回顾，
一片树林里分出两条路，
而我选了人迹更少的一条，
从此决定了我一生的道路。
这是人生的一个感悟，就像选择了计算机科学与技术这条道路一样，茫然后的执着，一直不懈努力。
美国诗人 罗勃.佛洛斯特：没有走的路
Robert Frost’s known poem: The Road Not Taken
黄树林里分叉两条路，TWO roads diverged in a yellow wood,
只可惜我不能都踏行。And sorry I could not travel both
我，单独的旅人，伫立良久，And be one traveler, long I stood
极目眺望一条路的尽头，And looked down one as far as I could
看它隐没在丛林深处。To where it bent in the undergrowth;
於是我选择了另一条路，Then took the other, as just as fair,
一样平直，也许更值得，And having perhaps the better claim,
因为青草茵茵，还未被踏过，Because it was grassy and wanted wear;
若有过往人踪，Had worn them really about the same,
路的状况会相差无几。Though as for that the passing there
那天早晨，两条路都覆盖在枯叶下，And both that morning equally lay
没有践踏的污痕：In leaves no step had trodden black.
啊，原先那条路留给另一天吧！Oh, I kept the first for another day!
明知一条路会引出另一条路，Yet knowing how way leads on to way,
我怀疑我是否会回到原处。I doubted if I should ever come back
在许多许多年以後，在某处，I shall be telling this with a sigh
我会轻轻叹息说：Somewhere ages and ages hence:
黄树林里分叉两条路，而我，Two roads diverged in a wood, and I–
我选择了较少人迹的一条，I took the one less traveled by,
使得一切多麽地不同。And that has made all the difference

1 介绍
2 Memcached是什么？
过去的一周时间里，我们都在讨论的核心是一个分布式内存缓存系统。实际上，我们把经常使用的LiveJournal对象都放到一大堆服务器的内存里。这些对象可以是用户信息，登录信息，颜色，样式，日记条目，意见，网站文字，等任何东西……
今天，Memcached被许多大型站点使用，包括Flickr，Slashdot，Wikipedia和Facebook，这只是一小部分。但是Memcached到底是什么？一个站点怎样从Memcached中受益呢？以下，我们将继续探索这些问题
