it means why is probably in a remote, hidden mountain village in Colorado.

I don't disagree. I tried to tell the product people that on several occasions, but it fell on deaf ears. So might as well do it right, eh?

Got around to profiling it last night. My code is faster, if you accept the cost of mystery.

Yeah, a ull is overkill. This code comes from a furious couple weeks of coding, an attempt at being clever and going for speed. I'm not sure if I accomplished either. The thinking at the time was that the constants might cache better. I know, don't be clever.

b52 maps each short url code to a unique number, 0-(52^5)
