It turned out that the clock can really keep time -- given "good enough" power supply. They were really designed with their small batteries in mind. Give them 2.4V (2x NiMH), and they gain time at 10minutes per two hours (and other glitches, like sometimes going into "time not advancing" mode, when seconds change but get reset to 0 when you stop watching them). Give them 3V (2x primary cell), and they fail to work, producing distorted, blinking display. Give them 1x primary cell, 1x NiMH, and they fail to work, too. But give them 1x new primary cell, and 1x almost empty primary cell, for 2.7V total, and voila, they actually start keeping time...

Pretty big side-effect
Timing and side-channels are not normally considered side-effects, meaning compilers and cpus feel free to do whatever they want. And they do.…

Complex cameras coming to PCs
It seems PCs are getting complex cameras. Which is bad news for PCs, because existing libv4l2 will not work there, but good news for OMAP3, as there…
