This post: https://discussions.apple.com/message/20156136#20156136 was a huge help after I upgraded OS X and couldn't get the correct printer drivers installed. Sure, it removes all the current printers, but adding them back is easy and one gets the newest drivers in the process.
I really like to listen to audio books as I spend a lot of time on the road. I've had several that we essentially "unlistenable" due to the narrator reading so slowly. With help from http://lifehacker.com/5458052/how-do-i-speed-up-hundreds-of-audio-files I created two chains in Audacity and could then use the File->Apply Chains... to the audio files:

I ran into troubles with exim4 on debian taking forever to start. Strace'ing it revealed it was trying to look itself up using DNS, ignoring what was in /etc/hosts and /etc/nsswitch.conf. I was testing a box before I hooked to a network that had a DNS server running. Commenting out everything in /etc/resolv.conf took care of things. What if I only wanted exim4 for local delivery, which I did? BTW, it also makes logging in with ssh a lot faster as sshd is doing reverse lookups.
