  1. But what's the bandwidth? on Physicists Promise Wireless Power · · Score: 1

    If the signal has a narrow bandwidth, you might be able to operate near 6.4 MHz without interfering with other devices. Also, I suspect the frequency isn't that critical.

  2. Standards needed on Physicists Promise Wireless Power · · Score: 1

    If this works, we need to define a standard resonance frequency NOW. I, for one, don't need a repeat of the wall wart debacle where every device needs its own charger.

    That's right, because in Soviet Russia, cliché posts mod YOU!

  5. Re:Car analogies on Making the Sounds of Vista · · Score: 1

    1970s-80s Japanese cars were rustbuckets yes, but no more than other cars of that era [1]. Mechanically and electrically, they were orders of magnitude more reliable than European cars. Back then, a car that never failed to start was a novelty, and it was the Japanese who made this commonplace.

    1: and they were by no means the worst offenders. Alfa Romeo deserves that dishonor.

    Slashdot, the only place where a blow-coffee-through-nose remark gets modded insightful.

    Yeah, what's with that? Everybody knows blow-coffee-through-nose remarks are Interesting, not Insightful.

    (for the observer, that is).

  7. Re: Reduce at the source on A Concrete Solution To Pollution · · Score: 2

    For petrol-powered cars, I'd call a 99% decrease in several rather toxic substances rather more than a token gesture. The chief remaining problem is CO2. For diesels, efforts are underway at the moment, with high sulfur content in US diesel being a large stumbling block.

  8. Re: Reduce at the source on A Concrete Solution To Pollution · · Score: 4, Insightful

    My biggest question is why have this in concrete? Other than the manufacturer sells concrete.

    Controlling pollution at the source is nice, but may not be enough. Emission laws for cars have been hugely successful, but there are still plenty of smog sources out there, not all of which can be cleaned up economically.
    We used to have huge forests that act as pollution sinks. If we can use our urban jungle to do the same, why not?

  9. Re: 30% is still a fair amount for nonenvironmenta on A Concrete Solution To Pollution · · Score: 4, Informative

    Note: the 30% quote is for pavement with this catalyst. Adding the catalyst to paint would cost much less (TFA says $120 for a five-storey building).

  10. Re: 30% is still a fair amount for nonenvironmenta on A Concrete Solution To Pollution · · Score: 3, Interesting

    FTA: TX Active not only hastens the decomposition of organic and inorganic pollutants, it also prevents their build-up on surfaces, helping to preserve a building's pristine appearance over time.

    So the long-term cost may be lower because you can spend less on cleaning your prestigious HQ.

  11. Re: HOW did you clean it up? on Worst Security Clean-Up You've Performed? · · Score: 2, Informative

    My parents recently had a virus on their computer. No big deal (just one virus), but Norton AV couldn't remove it and the manual removal instructions Symantec gave were rather convoluted (Recovery console, blah blah blah). Solution: pull the disk, stick it in a USB box and hook it up to my laptop. Eureka! The disk is inert (it's no longer the startup disk), so you can repair at your leisure rather than trying to beat whatever got started up during boot. You have a functional system during the procedure (if for no other reason than to keep the removal instructions handy) and no arcana like the Recovery console. Also, you've got a virus scanner you know isn't compromised.

    I know what I'll do next time.

  13. Re:On the cheap side ... on Core Python Programming · · Score: 1

    I've been using How to think like a computer scientist: Learning with Python. It's useful, but a bit terse. My programming skills are rather limited and rusty, so I got stuck halfway through the book. People who program for a living will find the book easy to digest, I expect.

  14. Re:Sounds like a good thing to me. on Google's Growing Love For the Mac · · Score: 1

    Web applications are useful for some situations, but I wouldn't want to run e.g. SketchUp inside a browser window. Like it or not, OSes aren't irrelevant now and won't be for years to come.

  15. Re:No offense... on Funding Cut For Arecibo Observatory · · Score: 1

    No you won't. You save only the (manufacturing the materials), which is only a small percentage of the cost of the F-22. The remainder has been spent already, on research and development.
    I'd expect an F-22 to have a marginal cost of maybe $50M.

  20. Re:In a related story ... on Voting Machines Banned by Dutch Minister · · Score: 1

    Secret service involvement is not a rumor. The press release (Dutch only) by the responsible Minister states that the AIVD (Dutch secret service) has examined these voting machines, and has concentrated on whether voting is remotely observable (Van Eck-type attacks). The press release doesn't mention GPRS-related attacks. What the AIVD found officially was serious enough on its own, and very plausible. No need for it to be a cover for another type of attack.

    No they haven't. They banned one specific voting machine, which has been demonstrated to compromise voter anonymity.

    Actually, what you describe is how the Nedap machine (which hasn't been banned) works.

    The machine that's been banned is the SDU NewVote, which uses a Windows computer and a touchscreen. According to the report, the AIVD could view the entire contents of the screen.

  24. -1, Doesn't Get It on Make Linux "Gorgeous," Says Ubuntu Leader · · Score: 5, Interesting

    People don't crave OS X because it's beautiful, but because it Just Works. The beauty of OS X is way beyond skin deep. To achieve it you need things like consistency, subtle cues that inform the user of what's happening, you need to remove clutter etc.
    You need to think about every element of the UI not in isolation, but in relation to all the other elements. Mere eye candy just doesn't cut it. Shuttleworth sort of admits this in the blog entry, but bulldozes over it earlier on, when he says I'm not talking about inner beauty, not elegance, not ideological purity... pure, unadulterated, raw, visceral, lustful, shallow, skin deep beauty.

    Sorry Mark, but you're starting at the wrong end here. You need inner beauty, in the shape of e.g. a consistent framework, and at the most fundamental level, just plain consideration of how the user interacts with the application, before you can start working on the skin.

    And that is why Linux distributions as we know them will never compete with OS X. You'd need to toss X and its bazillion GUI toolkits, and replace them with something new. Then you'd need to organize a Human Interface Police, whose job it is to kick developers who don't follow the guidelines. And I suspect that won't go over well among the Linux developer community with its "free to do whatever the hell I like" mindset.

    I've looked it up in
    - the most comprehensive dictionary (Van Dale) we have,

    Neither mention the word 'vrow'.
    The correct spelling is 'vrouw', plural 'vrouwen'.
