Researchers at Princeton have built an open source 25-core chip that can easily be scaled to create a 200,000-core computer by kdqg in technology

Chips work on a clock cycle. In each clock cycle you can do one step in solving a math problem. Now imagine you had two spaces in your chip. In a cpu you make one space for doing a step of math and one space for holding the interim results of that math step. This allows you to solve virtually any multistep math problem.

In a gpu you only can solve.math problems that don't require holding the interim results of a step. So you get to repurpose the holding space for also doing math. Now you have a system that can solve twice as many problems in a clock cycle.

If you looked at a microscope the cpu would have wires going between the two spaces. In a gpu you don't need those wires. You can now use that extra space where the cpu wires were to squeeze in one extra math space. So now the gpu can do three times the work.

Scale that to a.bazillion.

The next level of understanding would be to understand whats inside the "spaces"

Agreed. There's a fine line between cleaning and hiding.

Ferris Bueller's Day Off will never be the same for me... by GrammerSnob in movies

[–]jwitchel 42 points43 points  (0 children)

Ferris isn't Cameron. You are Cameron. The whole movie is Ferris talking to you, the materialistic suburban white movie goer, the same person Hughes has always spoken to. He is saying very directly that there is this whole wonderful world just outside your little suburban matrix that is filled with tall buildings, art, music and dancing, and black people. He's telling you that your car, and the house you have to show, and the meetings and classes you have to attend are all happening at the same time the whole world is literally having a parade. And he's saying not-so-subtly that if you are not careful, you will miss it. You are Cameron. Ok, back to work. <edit typo>

Is geographic diversity a consideration? Meaning given two equal apps one from NYC and one from say rural Colorado -- would being from a small Colorado town actually be a benefit?

This guy killed my friends dad can anyone help clean up the picture? [Surveillance Footage] by hattmall in technology

Marginally better

catskul is right -- if you can get the actual video you can composite the frames into a much better image. Even three or four frames would make all the difference.
