Comment Re:Why two wheels? (Score 1) 144

They shouldn't be in traffic in the first place, for starters.

True, but then again, automobiles shouldn't be driving into crosswalks when I've got the light, but that happened to me today - in fact, during the time since I wrote that last comment.

Today's incident wasn't a big deal, because I was watching the driver, and I could see she was looking only at oncoming traffic from her left, while I was on her right, trying to cross in front of her turn. So I waited, and resisted the temptation to slap the side of her car.

But that's also a scenario where the Elio would have been a bit more of a danger. If I'm watching the driver, that protruding wheel is only in my peripheral vision. That's different from a regular car, where the edge of the car is between us and easier to identify.

So it's a risk - the hard part is quantifying how big of a risk it presents.

Well, it's narrower - that'll help in many urban areas, and will make finding parking a bit easier. A two-wheel car is also a little less likely to take out pedestrians with one of those protruding front wheels.
But those advantages might be outweighed by other disadvantages - as you've noted, cost and complexity are concerns, and the actual performance of the balancing algorithms and such is still an unknown.

256-bit block ciphers are merely difficult to attack.

That is incorrect. It is impossible to brute-force a cipher like that, and it is extremely unlikely that someone has found a cryptanalytic break for modern ciphers like AES.

Unlike a block cipher, you can prove that a one-time pad is unbreakable, but that proof depends on the assumption that the random bits of the pad are completely unpredictable. Turns out that's a non-trivial problem to solve, and an especially difficult one to test.

"Nobody goes there anymore. It's too crowded." - Yogi Berra.

OK, that doesn't quite fit this situation, but you are only putting one variable into your equation - more roads. There's also:

  • - More population. A lot more - the use population has grown something like 25% in the part 30-40 years.
  • - More population in suburbs, and other changes to density.
  • - And as a consequence of the previous item, more miles driven per capita, especially in some areas. Just because teens aren't driving doesn't mean nobody is.

I haven't seen anything that lists any Apple funding, although some articles mention Rackspace.

The primary political tension I was referring to was the continual battle between the county government and the city government here. The city has a very large (and pretty good) library system (http://en.wikipedia.org/wiki/San_Antonio_Public_Library); they could have taken on this site as well. But it was probably easier to go bookless by not being part of the SAPL system (and Nelson Wolff, a county guy, couldn't get any credit if SA did it).

Turns out, this library is well within the city - it just happens to be funded by the county government (which isn't unheard of, although it was probably done for political reasons here).

I would argue that wi-fi and e-readers are not a complete replacement for a physical library location. Among other things, the building has useful services like desktop computers, meeting spaces, computer classes, and a place to pick up and learn about those e-readers.
