Star Trek fans were thrilled when an engineering firm last year introduced a "real tricorder," a handheld sensing device that records temperature, ambient light, barometric pressure, and electromagnetic radiation of a few kinds, but weren't as thrilled with the $400 price tag. Soon Trekkies who already own a Newton MessagePad can add Tricorder MP, a $69 utility expected this month from Sir Isaac Software that takes advantage of the Newton's infrared port and internal temperature sensor to scan the environment.

Sleep (and Lock) Your Screen
When you are walking away from your computer, it's fairly common practice to start your screen saver and lock your screen. But did you know that there is a built-in keyboard shortcut in Mac OS X to sleep the screen?
Press Control-Shift-Eject and your monitor sleeps without engaging the screen saver.
