Found myself tasked with reverse-engineering the Duo Pop appcessory this week. In case you’re wondering, base-station to iPad communication is handled via ultrasonic sound. EOM. b.
This bug may very well have been around for a while, but it seems that the Google Voice plugin for browsers (Safari, Firefox, Chrome) is very possessive of its webcam.

If you’re running PHP on a 32-bit system, you’ll need make sure that your install has been compiled with the -ffloat-store flag. Otherwise, the PHP process will enter an infinite loop when you try to perform mathematic operations on the floating number 2.2250738585072011e-308.
I have a new source of time-suckage, and its name is the Kinect. Back in December, someone hacked Microsoft’s Kinect.. allowing computers to interface and receive raw data from the full-body motion/gesture sensing device. A week or two ago, in early January, another group created an AS3 solution. The solution consists of a command-line socket […]
