I accidentally found a very interesting course from Berkeley today. The title is Mesh Generation and Geometry Processing in Graphics, Engineering, and Modeling by Jonathan Shewchuk.
Installing leJOS NXJ for Lego Mindstorm
I was trying to install leJOS to my Lego minstorm brick. I used ubuntu and got into trouble when I tried to flash the lego brick. I realized that the problem is that I didn’t have write permission to usb device. If I used sudo, I didn’t know how to export the environment variable NXJ_HOME….
Video stuff in Ubuntu
Switching to Linux means relearning of many old skills. I finally got DVD Decrypter working again. I first tried installing it in a guest XP under virtualbox but it doesn’t work very well. It does do ripping but the output is all messed up somehow. On the other hand, installing using wine goes quite well…
DNS problem of virtualbox
I wasted a couple hours today trying to figure out why my guest winxp has no connection. It is the third ubuntu machines that I have installed a virtualbox with a guest winxp. I am very satisfied with virtualbox. It is very fast and I can do almost anything I need for a window machine….

chkdsk is evil
As title. I erased everything in my drive with chkdsk /r. After frequent trouble with Cygwin, I finally decided to give Ubuntu a try. My drive had 3 logical partitions. I have one with WinXp 64, one with WinXp and the last one without any OS. I tried to install ubuntu in the third partition….
