Seeking Random Numbers. Must Pass Chi-Square Test. No Freaks.

Malasada had some little webcam she’d gotten a while ago as a promo item for signing up with an ISP. For a while, I’ve had in the back of my mind to use it to build a LavaCan. Because, you know, every home needs a cryptographically secure source of random numbers in hardware. Well, it seems like people were lucky to get this camera working with an allegedly supported OS. This guy heroically analyzed the signal between the PC and the webcam and came up with some sort of picture, but his write-up falls short of providing code.

Oh well. The Weecam’s off to the Alameda County Computer Resource Center, and I’ll give iwrandom a try. (But a webcam in the dark is so much cooler, drat it.)
