@Freakin Ijit: yes, real optics. You can hear the motor that drives them when the camera is focusing.

@Pete: I wondered the same thing. I'm guessing the programmer who wrote the code used the first timer they could think of which happened to be the real-time clock value. Wouldn't be my first choice either. But who knows...

Re: autofocus, my guess is that the software uses a Fast Fourier Transform (FFT) or something similar on samples of the live image data to count the amount of high-frequency information. Basically the more high-frequency information there is (after filtering out noise etc.), the sharper/more focused the image is. The software moves the optics around until it detects a maximum sharpness; that's why you hear it "hunting" for focus. Not unlike how someone with an SLR camera manually focuses it: adjust one way until you overshoot the best focus, adjust the other way a bit less, etc.

I think I know the nature of the bug. The number of milliseconds that can be counted by a 32-bit number is approximately 49.7 days (i.e. about twice "24.5").

Now, that's for an "unsigned" (non-negative) 32-bit integer. For a signed 32-bit quantity, once the number of milliseconds exceeds ~24.8 days, the millisecond count becomes the lowest negative number (and starts counting back up towards zero).

The bug is that code is using a signed 32-bit integer math instead of unsigned so for half of the span of 32 bits (24.8 days) the timer math used for the autofocus is choking on negative millisecond values.

Most power-assisted brakes (brake boosters) will fade after a while if the brakes are applied at the same as the throttle, because the brake boosters are driven by engine vacuum and the vacuum "boost" cannot be replenished while throttle is applied. That's not a flaw in the brake booster design, that's just how the system works.

180hp from 3.5L (and a V8)? Are they retarded?

Specs for the new Nano are up: video recording is: H.264 VGA video, 640 by 480 pixels, up to 30 frames per second with AAC audio

I always thought BMWs and their drivers had E.D.

You can't polish a turd, Beavis.

can has?

Ooh, want!
