Install XCache for PHP 5 on CentOS

XCache is a open-source opcode cacher, which means that it accelerates
the performance of PHP on servers. It optimizes performance by removing
the compilation time of PHP scripts by caching the compiled state of
PHP scripts into the shm (RAM) and uses the compiled version straight
from the RAM. This will increase the rate of page generation time by up
to 5 times as it also optimizes many other aspects of php scripts and
reduce serverload.

That is crazy, I did nothing why it crashed. And I tried Eclipse 3.3, the same problem.

Use WMS GetCapabilities XML+XSL+Javascript to create simple map client

The Extensible Stylesheet Language (XSL) includes both a transformation language and a formatting language. Each of these, naturally enough, is an XML application. The transformation language provides elements that define rules for how one XML document is transformed into another XML document.
The transformed XML document may use the markup and DTD of the original document, or it may use a completely different set of elements. In particular, it may use the elements defined by the second part of XSL, the formatting objects.

If you are one lazy programmer like me and have no time to read the document of log4j but still want to use log4j, try to read the following.

At least you'd better know that log4j is one tools to help you debug and log what happened with your code, anywhere and anywhen. I was used to use System.out.println() to debug my code, and I have written one function to do that:
