This Kerry Garrison tells how to build a full-featured PBX for less than $20 using rubber bands and other things you already have laying around the house. There is also a nice list of free office software. I noticed this Ultra@VNC because I keep telling myself that I need to use VNC, since there is still a Windows box in the house. But it’s easier just to ignore it and wait for it to go away. (From the free office apps it was only a click and a jump to MacMP3Gain, which looks so useful that I think I’ll actually give it a try.)
