Answers:

: Q: What happens if I accidentally check in a binary file to CVS but in ascii format? ^{(^)}

: A: The command to fix this is

cvs admin -kb filename

: Q: How can I crosscompile for the gumstix using lab machines? ^{(^)}

: A: Login to the compile1 machine in the lab. First, ssh to bracton.ece.arizona.edu, using your departmental ID. Then, ssh to compile1, as ssh user@compile1, and then your compile1 password. To do the compilation, use the crosscompiler that is stored in /home/compile1/svn/gumstix-buildroot-1161/build_arm_nofpu/staging_dir/bin/

: Q: How do I fix my broken fonts in Leopard? ^{(^)}

: A: Like this:
$ killall -u `whoami` ATSServer

To fix with a reboot:
% rm -rf `getconf DARWIN_USER_CACHE_DIR`

Then, reboot.

: Q: What's the deal with all of the machine names? ^{(^)}

: A: All machines are named after characters in That Hideous Strength by C.S. Lewis.

: Q: How can I reset my xorg configuration file in Kubuntu? ^{(^)}

: A: Ahh, so you messed up your xorg configuration, eh? This is why I recommend backups. :) Try this:
sudo dpkg-reconfigure -phigh xserver-xorg
Which may allow you to overwrite the file you messed up.
