My current favourite is this one. It's new, but it's a good question with some great answers that teach you a bit about how processors, or rather programmers, handle operations that don't fit inside a registers width.

How can a computer calculate exponential maths without overflow error?

I find the "fit inside a register" to be an important part because many people assume that the processor cannot deal with a number that is wider than its register, but there are ways around that kind of limitation that humans use every day with their own brains forgetting that computers can use the same tricks.

Forgot to mention, I'd be interested to write about this myself but it may take me a while due to other commitments.

  • You're more than welcome to start drafting this if you wish. I need a post for next week, so if you can make that great! If not, then we can schedule you for another week. Commented Jul 24, 2012 at 6:20

I like this one, because it's a good learning opportunity for people and applies to a broad audience. I'd also be interested in learning more about how this law applies to website owners outside of the EU.

Why are websites suddenly asking me about cookies?

(The answer relates to a new law in the EU regarding privacy and tracking)
