Things I Don’t Like About KDE
Yes, KDE is more powerful and more customizable than Gnome, as Linus said. But I think they really need to do some substantial work on user-interface design. Look at the intimidating menu of Kopete:
Not just Kopete, almost every KDE application has a menu like this. Outrageous. Couldn’t they figure out how to collapse the various [...]
Getting Card Readers to Work on Ubuntu Edgy
I have an Acer TravelMate 3000 laptop. The card reader did not work on Ubuntu Linux, and I didn’t care, because I didn’t need it. When I needed to transfer photos from my DC, I just used the USB cable. Recently I got a Zaurus PDA from eBay and needed to format an SD card [...]
A Distributed Algorithms Simulator
I have released my Distributed Algorithms Simulator (DAS). I made it mainly because we needed to demonstrate the algorithms in one of our papers. It is general enough to simulate and visualize many kinds of distributed algorithms. Major features include: * Visualize and verify distributed algorithms. * Run algorithms in automatic mode, single-step mode, or interactively. * View [...]
Emacs终于也有Antialiasing了
当年从Emacs改用gvim的很重要的一个原因就是Emacs的字体怎么看都不顺眼。现在Emacs终于开始支持 antialiasing （2006年都快过完了，感觉还呆在上个世纪…）。已经习惯了vim，所以没有换回的打算，不过还是忍不住装了一下玩玩。必须要用最新的 cvs snapshot 才行，这里可以找到 Ubunty Edgy 的包。
Compiz的确不错

今天装了compiz (hardware-accelerated desktop)。没做什么特别的设置就好了，对于一个Linux下还处于alpha状态的软件来说，有点让人意外。效果的确很impressive，感觉比Mac OS X还眩一些。Linux向一个能被一般用户接受的桌面系统这个方向已经走了很远。
可惜切换workspace的动画不能截图。

Enabling CPU Frequency-scaling in Ubuntu Linux on Celeron-M Based Laptops
I have an Intel Celeron-M based Acer TravelMate 3000. The Celeron-M does not come with the SpeedStep technology, so it does not support frequency-scaling natively. But I got frequency-scaling working with p4-clockmod. This is disabled in Ubuntu (up to Edgy) by default, because there’s a significant delay when changing frequency on-demand. The following comment can [...]

Ubuntu/Debian 下的 JVM crash 问题
TopCoder 的 competition arena 在 Ubuntu Linux 下运行时会因为字体问题 crash 掉。估计还有别的 JAVA 程序有类似的问题。
用 google 找了个测试字体的 Java 程序试了一下，是一个叫 Rekha 的字体作怪。只要把 ttf-gujarati-fonts 卸掉就可以了：
$ apt-get remove ttf-gujarati-fonts
不过这样也会把 ubuntu-desktop / kubuntu-desktop / xubuntu-desktop 等顶层的包卸掉，不过那些包本身没什么内容，应该不要紧。
另外发现了一个很好用的工具 apt-file ，可以查找某个文件所属的安装包：
$ apt-get install apt-file $ apt-file update $ apt-file search Rekha.ttf ttf-gujarati-fonts: usr/share/fonts/truetype/ttf-gujarati-fonts/Rekha.ttf
