BOUML is a free UML 2 tool box (under development) allowing you to specify and generate code in C++, Java, Idl, Php and Python.

BOUML runs under Unix/Linux/Solaris, MacOS X(Power PC and Intel) and Windows.

BOUML is very fast and doesn’t require much memory to manage several thousands of classes, see benchmark.

BOUML is extensible, and the external tools named plug-outs can be written in C++ or Java, using BOUML for their definition as any other program. The code generators and reverses are ones of the pre-defined plug-outs included in the BOUML distribution. See features.

BOUML是一个免费的UML2.0工具（还在开发中），可以生成C++, JAVA, IDL, PHP, Python的代码。

BOUML是一款跨平台的程序，支持Unix/Linux/Solaris, MacOS X(Power PC and Intel) 以及 Windows。

BOML执行速度非常快，而且不需要占用太多的内存就可以管理成百上千个类，具体可以看官方的性能评测。

The Sysinternals team at Microsoft today released another useful software utility for Windows called Desktops to help people who run multiple applications at the same time.

Desktops (v1.0) is a Virtual Desktop Manager that lets you create up to four different desktop screens for arranging all those open applications in a more logical and productive manner.

For instance, you could put all work related programs in the first desktop window, chat programs in another virtual window and so on. This makes life less confusing when you have dozens of programs running simultaneously on the desktop.

The software runs in your Windows taskbar. And you can very easily switch from one virtual desktop to another by pressing the keyboard shortcut or through your mouse.

如果MySQL升级到新的版本后，出现”1146 – Table ‘mysql.proc’ doesn’t exist”的错误，那么还需要升级一下系统表，可使用MySQL自带的mysql_fix_privilege_tables或mysql_upgrade命令来修复一下.

注：自5.0.19版本起，mysql_fix_privilege_tables已经被mysql_upgrade命令代替！

8月1日，PHP5.3的第一个Alpha发布了，粗一看，改动的还不少啊，这下终于支持Namespace命名空间了，而我们需要做的尽量多做测试，哈哈。

具体的一些新功能可以查看此链接：http://cvs.php.net/viewvc.cgi/php-src/NEWS?view=markup&pathrev=PHP_5_3
