Half-byte was hacked recently due to it using an old version of back-end software that was vulnerable to silly and easy security breaches. The site should be back to its full glory shortly. I’m taking the opportunity to make changes in security as well as the overall site appearance. Stay tuned. Update (2010/01/17): Half-byte.com should [...] How much current does a simple over the counter five dollar laser produce when hitting a small solar panel? I wasn’t sure, so I did a little experiment. Using my handy multimeter, I determined the laser circuit was 4.5V at 25 mA. Since W = V * A, 4.5V x 25mA is 112.5mW. Now that’s just [...] There’s a good tutorial over at Instructables on making custom ethernet prongs out of zip-ties if the original snapped off. I had a busted cat5 cable causing me trouble and, surprisingly, I had the right size zip ties stowed away in my electronic gear. So, I gave it a shot.

It was frustrating spending hours debugging only to find out the compiler wasn’t handing an instruction [...] Many companies are producing minute PC’s for different purposes. Some create them for smart home utilities, where as others create zero space thinclients. Marvell has created a cheap, pretty powerful, plug PC call the SheevaPlug.

Most of the time it is clothes or a mattress or books. Books are fun to look through, but they are rarely worth keeping. Most people have a bad taste in literature [...] Every so often I go to the monthly talk hosted by BayCHI. It’s free and is at PARC, which is conveniently located a mere 200 meters from the company where I work.
