Matlab: Fatal error on startup: Failure loading desktop class

Updating jre messed up matlab configure file again. Removing classpath.txt in ~ fixed the problem.

MacPro CD/DVD tray problem in ubuntu

I was able to eject a cd/dvd in unbuntu 9 from the command line using "eject." Somehow it doesn't work anymore in 11.10, neither does "eject /dev/cdrom" or "eject cdrom" work. By going into the /dev directory, I found that cdrom is just a link for sr0 in my MacPro, and "eject /dev/sr0" did the job! There is also a sr1 which I thought was the 2nd tray in MacPro, but "eject /dev/sr1" didn't do anything.
