More stuff to read

• Word-by-word diff of GPLv2 and v3
• New version of Unix Backup and Recovery, by W. Curtis Preston. The first was amazing; this one covers Windows and Mac OS X as well. WANT.
• Good reading and good suggestions. I need to alias ls, fg, mutt, sudo, and to shorten my alias for SSHing to my webserver.
• I think I finally figured out what was going on when my desktop machine at work had a suddenly borked mouse/X relationship: double-clicking was inconsistent, single-clicking was inconsistent, but the keyboard still worked. It happened again a few days ago, and I managed to run xev and verify that things really were messed up: the mouse and all its clicks and motions just weren't registering at all. I managed to figure out what was (probably) going on when I came across this link. In the end, what worked for me was switching to a console and running cat /dev/input/mouse1. Don't know why (yet!) but that seemed to reset everything.

Still to come: Why upgrading is the most important thing EVAR.
