Enchanted, Fire Protection III

Hey David,

awesome of you to do this AMA! I've been really looking forward to this. So, here it goes: What was your scariest computer related problem that you have had to deal with in real life? What would McKay have done?

It wouldn't be too far off to put Vapp in a 738 at 135 knots, which is about 155mph.

Wow, 6 kilometres, that's about 3 nautical miles, you'd usually still be at around 1000ft!

Let me explain why the camera scans the images:

Basically a CMOS sensor is made of lines of pixels which each build up a voltage as photons hit it (photoelectric effect). The more pixels hit the pixel the larger the voltage in the pixel is and the brighter it will be on the later image. But in order to save the voltage as data the camera scans the image line by line. And that takes just a little bit of time. You could probably calculate that time if you knew what RPM the propellers were turning, sounds like a good plan for some other day :P

edit: CMOS not CCD, my fault.
