A: You´ve probably heard of the Wi-Fi antennas made from old Pringles cans, but those are tricky to build and often require special connectors and soldering. A much easier option is a parabolic reflector antenna. You can whip one together using an old shoe box, tape and some aluminum foil in about 30 minutes, and it will double or triple the range (in a single direction) of just about any wireless access point with an external stick antenna.

A: If, like me, you obsessively comb dozens of news sites and blogs to get your daily info fix, RSS is a godsend. Instead of actually visiting each site, waiting for your browser to load pages and slogging through ads and graphics, you can breeze through the latest content from all your favorite sites in one text-only window.
