My crazy idea is to have one of these hours be sponsored by the letter R and the number 7, as if it were an episode of Sesame Street. We'll be essentially anonymous to the show's listeners.

It'll cost some money (the total for a sponsorship is $150), but I can put up a lot of it, and I have at least one co-conspirator.

Anyway, let me know, by comment, email, or private message, if you want to be part of this. Or if you have any questions.

If you find statistical analysis at all interesting (and I would give odds you've spent some time reading fivethirtyeight.com), her blog is highly recommended.

I suspect that Bert has something to do with this.

I'd love to hear what you think!

If the popular version of Moore's law (computing speed increases by a factor of 2 every 18 months) were to apply continuously,(which it doesn't) at what point does a process become not worth hitting start on.

That is, if I have a program that takes 80 years to run, I shouldn't start it now. I can get it done in 23 years by waiting 3 years, at which point the program will only take 20 years. So at what point (expressed as current time to completion) should I hit start?

I have an answer, but I'd like someone to check my math. So if you're interested in trying it yourself, do so before clicking on the cut-tag.

Run on a unix machine, pick one-character arguments if desired, pipe through uniq.
