synergy
one more nerd post before i go:
synergy is one of the coolest new things i’ve tried in a while. it’s a little free, open-source program that you run on 2 or more computers (they can be any mix of mac, pc, or unix). after a little configuration, you can use the same mouse/keyboard on one machine to control the other! alright, it’s not exactly earthshattering, but seeing it in action is pretty cool. for example, i’ve got my work laptop setup on the kitchen desk next to my minimac. while using the laptop & it’s mouse/kb, i move the cursor off the left side of the laptop screen, and it suddenly enters the mac screen from the right, as if it’s an extension of the same screen. and then i can completely control the mac from the laptop’s mouse/kb. if that excites you, you’re a dork, too.
