My only experience is with charter. Their service itself is usually pretty good, but I hate their website. You can't find straightforward information on what individual services cost, and even finding a channel listing is difficult. On more than one occasion I've searched for services available at my house--where they make me enter my exact address--and their website tells me that they do not service my area.

It really frustrates me that the companies that run the internet don't care enough or aren't required to make basic information about their services available.

Good point. Get two.

Am I the only one who's been waiting for years to nail someone who "corrects" me for saying "pdf file"?

This is a very capable calculator for under 20 USD. The two things that really impressed me about is are that (1) it can do arithmetic with and simplify square roots, and (2) it can do numerical integration and in some cases give exact answers. The numerical integration can be painfully slow, but it can recognize that, for instance int_{-1}^1 \sqrt{1-x^2} = \pi/2.

They have to get to the ISS because they are running out of oxygen. Sounds a lot like Space Camp.

Because of performance-based funding, and programs like Complete College America.

This reminds me of the movie Chopping Mall, where security robots patrol a mall, and (big surprise) a bunch of teenagers get stuck in there overnight.

you get nothing in return

FB users get a significant amount of utility out of Facebook, and of course it comes at a cost. It looks extremely lop-sided because there's only one facebook and there are a billion or so users, but saying that users get nothing from it is just as stupid as saying that it costs users nothing.

Here's a good visual of that concept.

but the Antarctica Journal of Mathematics has such a great webpage.

Thomas Gold wrote a book that seems very pertinent to this.

You can with an iPhone 4. The voice commands work well and don't send anything to Apple.

You are correct, except that the parent was talking about the definition of Mersenne numbers, not Mersenne primes.

I'll second the .28 mm uni-ball signo. It's the best thin-line pen I've ever used. It's great for doing neat, precision writing, but I can't write very fast with it. In my opinion the .18 is a little too small. I haven't tried the .38 version.

I've also tried the Pentel Slicci .25 mm pens, as mentioned by other posters, but I don't like them as well.

For a thicker-writing pen, I highly recommend the Uni-ball vision elite micro.

Rucker's "the fourth dimension: toward a geometry of higher reality" is a very good read, or at least i really enjoyed it when i was in high school. Much of the book is about Flatland, with a lot of commentary and additional ideas about A. Square. I'd recommend it.
