UPDATED: fixed the link -now it points to the same article LifeHacker was linking to (I can't find the LifeHacker post anymore). Sorry about the UPS package tracking thing.

I’m generally not one to recommend doing anything that might void your warrantee… but this one really appealed to the geek in me. LifeHacker links to DD-WRT, an open-source firmware replacement for wireless home network devices. Lets you get under the hood and do all sorts of interesting things…
