Dean Lee — Sat, 28 Apr 2007 15:03:21 +0000

This small wordpress plugin enable syntax highlighting of code snippets in your post using Google Code Prettify.

Notice: you will need to have JavaScript enabled in your browser for this to work.

I had developed another Source Code syntax highlighting plugin using Geshi before,but they are totally different things.with Geshi,code is parsed on the server side,no javascript is needed.

It’s hard to say which is the better,choose one based on your own needs.

FAQ (from http://code.google.com/p/google-code-prettify/)

Which languages does it work for?
The comments in prettify.js are authoritative but the lexer should work on a number of languages including C and friends, Java, Python, Bash, SQL, HTML, XML, CSS, Javascript, and Makefiles. It works passably on Ruby, PHP and Awk and a decent subset of Perl, but, because of commenting conventions, doesn’t work on Smalltalk, Lisp-like, or CAML-like languages.
How do I specify which language my code is in?
There’s no way to tell it which language because would complicate the interface. If it doesn’t guess the language properly, that’s a bug.
Which browsers does it work with?
It’s been tested with IE 6, Firefox 1.5 & 2, and Safari 2.0.4. Look at the test page to see if it works in your browser.

Permalinks Migration Plugin for wordpress

Dean Lee — Thu, 02 Nov 2006 18:51:03 +0000

With this plugin, you can safely change your permalink structure without breaking the old links to your website,and even doesn’t affect your search engine rankings.

introduction

Many people want to change their permalink structure,for example, from /%year%/%monthnum%/%day%/%postname%/ to /%category%/%postname%/

But doing so will make all pages indexed by search engines become invalid,moreover, losing visitors from other sites or bookmarks that links to you.

There is a way to tell the search engines (and browsers) that the page has permenantly moved, and that the old address should be replaced by the new one . It’s called a “301 Redirect”, also known as a Permanent Redirect.When you do this, Search engines will update their indexes quickly and you won’t lose your pagerank.you will continue to receive traffic as though nothing had changed. This works for search engines, bookmarks, and links from other sites.

By now, you know how can you change your permalinks without losing the traffic you’re already getting. You can download this Permalink Migration Plugin to achieve this for you.

This plugin will generates a “301 Redirect” when user or spider visit your site through old permalinks,and redirect them to the new permalinks of the same post.

Do not fear to change your permalink structure now, you would never lose any visitors due to changed addresses.

Convert Ip Address To Geographic Location

Dean Lee — Wed, 11 Oct 2006 18:27:34 +0000

网上有不少关于如何使用纯真IP数据库(QQWRY.dat),来查找IP所在的地理位置的文档和源代码，但基本都是java实现，很少有C的，而且大部分都使用了打开文件句柄，通过文件指针的多次跳转来实现单次查找，运行效率很低，尤其是在短时间内需要执行大量IP->地理位置的转换的场合，这种方式的运行性能基本是难以接受的。

因此我写了一个c++的CIPSeeker类，该类在初始化时将qqwry.dat装载进内存，之后所有的查找都通过内存指针来进行。同时为了方便在其他脚本语言中提供IP地理位置查找功能（asp或者C#,vb等），另作了一个COM控件来包装这个类。

出于把问题简单化和性能上的考虑，该C++类不支持多线程并发。如果要在多线程环境下并发查找的话，为每个要使用IPSeeker功能的的线程创建一个单独的CIPSeeker的实例就可以了。封装的com控件使用apartment线程模式，所以不用担心多线程问题。

使用方法

先下载最新版本的纯真IP数据库，解压缩之后将QQWRY.dat拷贝到应用程序同一目录下（如果是使用com控件，拷贝到com控件所在的目录。

CIPSeeker theSeeker;
theSeeker.Create((HINSTANCE)GetModuleHandle(NULL));
char szLocation[256];
theSeeker.getIPLocation("202.101.103.55", szLocation, _countof(szLocation));
printf("the Location is:%s", szLocation);

Set obj = server.CreateObject("IPToLocation.Seeker")
Response.Write( obj.GetLocation("202.101.103.55"))

Download OpenSSL for windows

Dean Lee — Tue, 03 Oct 2006 08:25:04 +0000

openssl-for-windows,host on google code,is an clean and lightweight OpenSSL library for windows(both 32bit and x64 version).

all versions are compiled in the assembly language routines with Microsoft Visual Studio 2005 and Microsoft MASM as “Multithreaded(/MT)”,you can using it with any version of MSVC.

Download openssl for windows

files included in this library are listed below:

|bin (libeay32.dll, ssleay32.dll,openssl.exe)
|include
|– — openssl (openssl head files)
|lib (libeay32.lib,ssleay32.lib)

if you find it useful, a time saver,or even just mildly interesting,then my effort was worth it.
if you have any suggestions on how to improve it, I’d love to hear it.
