I am proud to announce the winners of the US$100 prize. As you may have noticed, I committed a driver today that allows one to make a /dev/jogdial and read jogdial/button events from it. While the driver is embryonic in many ways, it is sufficiently functional for the awarding of the prize. I have decided to award the prize to Andrew Tridge and Ian Dowse. The former for his page at http://samba.org/picturebook/ which has some sample code (for Linux) that illustrates how to talk to the device, and the latter for a piece of demonstration code that works entirely in userland that he e-mailed me. The latter, along with acpidump output, was largely used to craft the driver. Each of the winners is receiving a copy of this message and is invited to direct me as to where to send their US$50. If I don't hear from them, then donations in their name will be made to the FreeBSD foundation (eventually) along with the US$100 won by Cameron Grant in the first challenge. I think the prize money for the next one of these will go up a bit, as having to split US$100 is a little cheap, I think.
