IntelliJ IDEA的开源版为IntelliJ IDEA Community Edition，使用Apache 2.0许可证。收费版为Ultimate Edition，与开源版本不同的是它支持更多web框架、语言和部署工具等。两者的详细区别可浏览这一网页。

我被Java烦着了。
在Ubuntu里，安装程序很简单，apt-get，.deb，直接安装就好了。真正是使用方便、只要你知道“名字”，千奇百怪的名字。不过慢慢会掌握的。
昨晚我升级到9.10a6不成功。导致花了一个上午安装ATI的驱动。原来可没有这么麻烦呐。dkms:(幸运的是搞定了。
安装openproj。安装完成之后方块出现了。跟openjdk里的细瘦文字不同了。竟然是自动安装了sun的jdk。这个修正方式又不一样了。
1. sudo mkdir /usr/lib/jvm/java-6-sun/jre/lib/fonts/fallback/
2. sudo ln -s /usr/share/fonts/truetype/wqy/*.* /usr/lib/jvm/java-6-sun/jre/lib/fonts/fallback/
如果是openjdk的话，居然要调整的是系统->首选项->外观->字体。。。
Java啊Java，终于明白为什么现在喜欢Python了。

对Java开发者来说，最近可以说是一段有趣的时间。被Oracle收购后，Java的保管人Sun Microsystems的业务正在被Oracle一步步合并，而同时一个重要的Java新规范正接近完成。
自从2006年度JavaOne大会上Java EE规范获得批准以来，Java EE 6本应是企业Java的第一次规范更新。今年的JavaOne 2009已经曲终人散，但是我们仍没有看到Java EE 6敲定的消息——甚至连提到现在进展如何的消息都很少。
