Apple’s official list of stuff not compatible with OS X 10.6 Snow Leopard.
Also Espresso, possibly Growl, and others listed at Wikidot’s Compatibility List.

From “Automatica Blog – Specialist Apple Mac support for creative professionals, Melbourne Australia”, edited slightly for clarity and grammar:
Use this command to determine the IP address of the DHCP server your Mac is currently using:
ipconfig getoption en0 server_identifier
You can also do more with ipconfig, such as determine the router address for an interface:
ipconfig getoption en0 router
Simple but nice tips. Sooner or later I’ll get my site looking a little better.
