Comment Gimbals (Score 3, Interesting) 325

Dumb question, I suppose. But, given that the earth rotates, and given that the flywheels will have a huge angular momentum, are they gimbaled? The article says they're suspended in a vacuum, levitated on a magnetic field, which is cool. But if they're not gimbaled a huge amount of energy will be wasted fighting precession as the earth rotates.

I assume the people making these things are smart and know their shit. I'm just curious how a problem like this is solved. If not gimbals, what?

Comment We are not the audience. (Score 1) 277

Every post here is (understandably) negative. But, come on kids, we are not the audience here. Programmers are not the audience. Hackers are not the audience. Gamers are not the audience.

People who spend all day on facebook, gmail and last.fm are the audience. And this is probably a very good solution for them.

Comment Re:And Adobe can't do this, why? (Score 1) 356

Actually, adobe is. I can't recal the name of the project, but Adobe's writing a canvas-based flash renderer in JS.

Canvas is actually the right way to go, because despite all the comments in this thread about how HTML-5 is "officially as powerful as flash" now, the fact is flash does still have some advantages, like bitmap filters.

Those can be implemented from scratch in a canvas-based renderer, whereas any attempts via dynamic SVG will be subject to whatever support SVG has for filters.

In short, by implementing a from-scratch canvas-based renderer, Adobe gets full control over the pixel pipeline, which allows them to get pixel-perfect rendering. Flash is, believe it or not, a very high quality renderer, and Adobe likely doesn't want to lose that.

Hey, I just want to thank you for a good & sensible writeup.

I am one of those people who architect his life about sensible transportation. I recently bought a house in washington dc, and ride my bike to work daily. I've been a bicycle commuter for 10 years, and have made my living arrangements favor bike commuting accordingly. It's actually pretty wonderful, I spend 15 minutes on my bike every morning and evening to get to work ( and if necessary, to stop at the grocery store on my way home ).

Frankly, it's an absolute joy. My colleagues bitch and moan about traffic, yet they insist on living as far as possible from where they work and spend more than half of every day.

Anyway, I had to comment simply because so many internet discussion threads about cycling tend to devolve into name calling and internet-tough-guy-ism.

You know, I just wanted to let you know that we yanks know perfectly well what an arse is, we don't need to have your mystical moon-man speak translated for us.

Yes yes yes, it must make you feel all high-falutin-etc to condescend to let us in on your colloquialisms. But it's not a secret. We know what arse means. We also know that you call a car's trunk a "boot", and that you like to spell color with a 'u'.

We get it. Carry on.

2 things:

1) You'd better figure out how to keep the world from just getting hotter and hotter. That free energy's being turned into work, after all.

2) You're using what would be the greatest advancement in the entirety of human history, to play a prank? On all of humankind?

Sir, you have my respect.

One man's "stupid gimmicks" is another man's graceful and easy-to-use system.

I know the above sounds snarky, but I worked on Mac OS Classic for years, and was a linux user at home for years as well. I was *very* put off at first by OS X's eye candy and general fooferah. And then I actually used it ( 8 hours a day at work ), and realized it was fantastic. I ditched my Slackware running thinkpad for a powerbook, and never looked back.

Submission + - General Motors: Driverless cars ready by 2018

Gregor Stipicic writes: " Cars that drive themselves — even parking at their destination — could be ready for sale within a decade, General Motors Corp. executives say. "This is not science fiction," Larry Burns, GM's vice president for research and development, said in a recent interview. GM plans to use an inexpensive computer chip and an antenna to link vehicles equipped with driverless technologies. The first use likely would be on highways; people would have the option to choose a driverless mode while they still would control the vehicle on local streets, Burns said. He said the company plans to test driverless car technology by 2015 and have cars on the road around 2018. "
