  1. Two words: on Securing a High School Windows XP Computer Lab? · · Score: 1

    No games

  2. not even close to the same but ... on Teen Plays Videogame With Brain Signals · · Score: 4, Interesting

    Not close to the same but a few years ago I bought a used Zenith TV with built in Pong. Great deal, but it didn't have the controllers. Rather than build them right, my brother and I stuck stereo wire into the controller ports and held the bare wire ends in our hands. By carefully squeezing and releasing we could alter the resistance through our bodies (ok, it was altering the contact resistance mostly). We didn't have much problem playing but the method was so sensitive that we had to sit completely motionless without talking. We looked like a couple of zombies playing Pong with our minds. Too bad the TV fried itself in 3 weeks.

  3. For a Firefox user: on IE7 To Ship With Windows Patches Tomorrow [Not] · · Score: 1

    For a Firefox user such as myself, can someone give me a link or explanation of the pro's and con's of putting IE7 on my XP box? Browsing experience doesn't factor in, so are there other factors to consider?

  4. diabetic monitoring on 20 Tech Ideas VCs Want to Fund · · Score: 1

    I love how they want an implantable monitor. Expecially for glucose. That's been a major objective in diabetic research for decades. Millions have been spent on it. Chances are any new idea these guys get will fail as badly as the old ones. Oh, it'll get solved someday. But it sure won't be from some guy reading CNNMoney wondering what to do with his fabulous glucose monitor idea. Heck, they could probably sell the tech to novartis or lifescan for a lot more money than they'd see from VC's.

  5. The reason... on 20 Tech Ideas VCs Want to Fund · · Score: 2, Insightful

    Don't forget, this is a list of projects they are willing to discuss publicly. They don't have to worry about someone stealing an old concept for a product and they might just get someone to call them up with a way to do it. They guard the innovative stuff a little more jealously.

  6. duh! on Billions of Planets In Milky Way? · · Score: 1

    Let's see ... 200 to 400 billion stars in our galaxy. Gee, you'd only need 1 in 200 stars to have a planet for there to be billions of planets. That doesn't seem like a stretch considering how many binary stars there are (5-10%) that there might be other chunks of stuff floating around stars.

  7. Re:Sounds Good, except on Magnetic Ring Could Launch Satellites, Weapons · · Score: 1

    No, sounds true. Besides the magnetic field, there is the RF field for getting the protons to wobble. Large metal pieces heat up like they were in a microwave oven. Small pieces seem to do fine.

  8. BCD wallet on Top Ten Geek Wallets · · Score: 1

    My brother would get a new wallet ever month from his wife. Turns out her BC pills came in a tyvek pouch the same size as credit cards.

  9. Re:huh on US Population to Top 300 Million · · Score: 2, Insightful

    To be fair, Native Americans didn't just spring from the ground (some creation stories not withstanding). They were just a bit quicker. Not to mention there were at least two waves of Native American imigration. "Hey poser! Your tribe has only been here 12,000 years. Ours for 18,000. We're REAL Native Americans."

  10. Re:math? 2000g for hours? on Magnetic Ring Could Launch Satellites, Weapons · · Score: 1

    Heck no! Take that back! Them's fightin' words!

  11. Re:Sounds Good, except on Magnetic Ring Could Launch Satellites, Weapons · · Score: 1

    Ah, but compare that to being inside the room. Most MRI's run 0.5 to 1.5 T, which is 5000 to 15000 gauss. 5 or 10 gauss is no big deal.

  12. Re:Here: on Magnetic Ring Could Launch Satellites, Weapons · · Score: 1

    Yeah, I caught the tail end of a show about it. They talked about the GPS circuits withstanding firing. Probably hideously expensive, but a nice tactical weapon.

    On a side note, I've known people who build fuses for artillery. It amazing that the things don't blow up randomly. Both from subjecting a detonator to 20,000 g's and from the shoddy QA. Had a buddy quit over one incident that he couldn't stomach.

  13. Re:Libel on Firefox Zero-Day Code Execution Hoax? · · Score: 1

    Or is it really slander? Either way, the Mozilla Foundation might not thing the prank is very funny and decide to spank these guys.

  14. Re:math? 2000g for hours? on Magnetic Ring Could Launch Satellites, Weapons · · Score: 1

    It's going in a circle. The 2 hours is to accelerate its speed to mach 23 (think in terms of a whip-around-the-head sling). The 2000g's comes from going mach 23 in a 2 km circle.

  15. Here: on Magnetic Ring Could Launch Satellites, Weapons · · Score: 4, Informative
  16. Re:Nuclear fueled payloads... on Magnetic Ring Could Launch Satellites, Weapons · · Score: 1

    "Flinging" payloads uses less energy than chemical rockets. Chemical rockets must haul the payload plus fuel plus fuel tanks plus rocket into orbit. Only a tiny fraction of the chemical energy ends up as kinetic energy in the payload. Assuming you accelerate a payload in a vacuum on a magnetic sled, making friction very small, you can get a sizable portion of your expended energy as kintetic energy of the orbiting payload. Yeah, you burn some off with atmospheric drag. But on the whole, you come out far ahead. And the capital equipment is easier to design, maintain, and reuse than, for example, the Shuttle.

    It's the 2000g part that is the difficult part. Oddly, casings for nuclear fuel for satellites may the only component currently strong enough to withstand such acceleration.

  17. Re:Sounds Good, except on Magnetic Ring Could Launch Satellites, Weapons · · Score: 1

    I'm thining it's a coincidence. Birds do use magnetism for navigation. But they don't just blindly follow field lines. Otherwise they'd be smacking into mountains, trees, buildings, etc. during migrations with or without MRI's around. Also, MRI's are heavily sheilded.

  18. Re:Read what Warren Slocum has to say. on Will the Next Election Be Hacked? · · Score: 1

    The short answer is that Americans despise the UN. As much as we hate our own politicians and suspect them of lying, we view the UN as far more corrupt. We are also very touchy about sovernty (yes, there is obvious irony there). You will see varying degrees of contempt, but you probably noticed that every discussion is based on how we can monitor ourselves (currently, every polling place has monitors from both parties who would love to point out cheating from the other party).

    As for touch screens for the blind, the legal definition of blind includes people with extremely poor vision, but still with some sight. With large enough lettering, they can understand what is written.

  19. My thought exactly on BBC Signs 'Memo of Understanding' With Microsoft · · Score: 1

    MOU's are frequently non-binding. Both parties in agreement, but not locked in yet. Sort of like a couple getting engaged.

  20. Re:Everyone is familiar with his earlier invention on China Claims Successful Fusion Power Test · · Score: 1

    Hmmm. That might just prove the guy's point. Farnsworth invented the insidious tv. Maybe he shouldn't be trusted...

  21. Re:One way to solve the problem... on Group Fights Politicizing Science and Engineering · · Score: 1

    Ah, but at least they HAVE an area of expertise that is useful. Most career politicians don't even have that (unless you count an MBA or law degree). So by your own logic, we should elect scientists and engineers before career politicians.

  23. Congrats on China vs U.S. in an 'Internet Race' · · Score: 1

    This is one of the few times I've seen "fascist" used correctly. With it being thrown around so much, I wondered when it really applied. Wikipedia to the rescue. Not sure I get all the nuances, but China seems to fit. Authoritarian, nationalist, strong government influence of private companies. Strange to think that when folks point to corporate influence of US government, that's a sign of the US not being fascist (not making a judgement, just saying the term no longer semantically correct). And islamofascist is a total semantic screwup.

    I can't find a reference, but some show several years showed trout (fingerlings?) being used in Rome to test the quality of the water coming from aquaducts. Can anyone confirm or refute?

  25. protocols on EU And Microsoft Clash Over Vista Security · · Score: 1

    I believe Apple isn't a target because the EU's complaints are about interoperability between clients and servers. Since OSX is built upon BSD/Unix protocols, the protocols are already well publicised. MS on the otherhand keeps the details of its protocols ambiguous at best.
