  1. Re:Looks nice. on Asus Promises 12-Hour Battery Life In New High-End Laptop · · Score: 1

    You forgot 6) Typical exaggerated tech promises.

    Come on, when was the last time you saw a battery life claim that wasn't slightly exaggerated, wasn't done under absolutely ideal (or even unrealistic) lab conditions, or otherwise didn't hold up under your own measurements?

    Unfortunately, few if any manufacturers explain battery life testing methods, so it's impossible to compare between vendors. Still, I might be in the market for a similarly spec'd machine with good battery life by the time this comes out. I'd like to see how close it comes to this claim.

  2. Re:Dangers of blocking on US Agency Blocked Cellphone / Driving Safety Study · · Score: 1

    IANAP (I am not a pilot), but I know a few people going for their licenses right now, and I get the impression that pilot to tower communications are all business. Each side knows what the other is going to say when he says it, kind of like a script, and it's all both relevant and necessary to the task at hand (flying the plane). It's a bit different than the highly improvisational, distant-focused conversational style employed by multitasking commuters.

    FAA regulations prohibit talking about non-flying related things between crew members during takeoff and landing approaches, and a violation of this reg was blamed for causing a crash near Buffalo earlier this year.

    I agree that we'd be better off if people adopted the no-nonsense conversation style of pilots while talking on the road, but I doubt many would go through a certification as rigorous as pilot training to gain the privilege. That said, a study probably wouldn't hurt. Even if it fails, it might quiet those who insist "Well I can talk on the phone while driving quite safely enough, thank you very much! I need to call you back, there's a telephone pole in my engine compartment."

  3. "innovative handsets?" on Senators To Examine Exclusive Handset Deals · · Score: 3, Insightful
    From TFA:

    the introduction of the iPhone has spurred many iPhone substitutes such as the HTC Touch, Blackberry Storm, Google G1, and several Samsung and LG models.
    -AT&T

    In other words, exclusivity deals breed ripoffs. Yeah, that's one form of competition, but it doesn't really seem like "innovation" to me when the release of one product that everyone wants causes every manufacturer to try to make an exact copy with a different exclusivity deal. If everyone carried the iPhone, these companies would be trying to differentiate themselves by coming up with the next big thing, not making copies of the last big thing.

    wireless carriers would have less incentive to develop and promote innovative handsets.

    I'm not from this industry, but I don't believe wireless providers develop handsets. Handset manufacturers (e.g. LG, Samsung, Motorola, etc.) do.

  4. Re:Get an RC plane on Best Way To Build A DIY UAV? · · Score: 1

    Although your average laptop has quite enough computing horsepower to run a basic flight control system, I recall a similar project I saw demoed at college found that the downlink of telemetry and transmission through the radio introduced a little too much lag time for performance to be acceptable. Then again, that project was demoed on a helicopter. A fixed wing aircraft might be a bit more lag tolerant.

    Although there is a case to be made for doing the math on the ground, for right now it's probably better to carry the flight control system on board.

  6. UAV tried to kill me on Best Way To Build A DIY UAV? · · Score: 4, Informative

    The last time some of my friends tried doing an automatic control system, the plane turned straight toward the flight line and tried to kill us all!

    Unless you have extensive experience designing them, I would recommend going with a kit plane for hardware rather than trying to build one from scratch out of foam boards. The reason for this is that you will start out with a design you know is flyable and has the stability properties you want. One of the classic errors in model-scale UAV design I've seen people make is trying to design the craft from scratch only to discover that their control surfaces are poorly sized, the thing is dynamically unstable, and it requires hand-made spare parts after every flight.

    I think an ideal platform for a UAV like you describe would be a foam flying wing with maybe a 3-4 foot wingspan. The flying wing design would at least in theory allow you to decouple some equations which would be difficult to do in traditional fused aircraft and impossible to do in helicopters. Also, unibody construction makes it easier to land without landing gear. Landing without some pretty complex rangefinding hardware is tough, even for a computer system. Doing a skid landing on that huge wing surface with a rear-facing prop will add some margin of error to your landing sequence. If possible, get an ARF (Almost Ready to Fly) model. They come with airframe, power system, and sometimes all the servos. All you need to add is the radio equipment (I assume you are going to have a manual override backup. No, really. You're going to want a manual override.). Expanded polypropylene foam is actually more durable than a lot of people give it credit for, and replacement parts for these aircraft are easy to find.

    If you're going to make a workbench designed for kids, a neat design feature would be to make it possible to grow with the kids. Maybe some nesting tubes for legs would allow it to change in height over time.

    Apart from that, look at the surface of the bench. Whether you want to use wood, laminated particle board, or lego base plates, making the surface extendable can help small arms reach the back, then expand horizontally as they need more bench space.

    My primary linux box has a FireGL T2. I've been through this level driver hell, and yet I am inclined to agree. The weekend after ATI releases the source code (which, when reverse engineered, may reveal in great detail the workings of the proprietary stuff in their chips that makes them go real fast), every chip manufacturer in China will be making unlicensed knockoffs of their chips (Every chip manufacturer in China is making mostly licensed knockoffs for now). A lot of R&D went into making the stuff that would be revealed in the source code.

    You can't just expect a company like ATI/AMD to give up the secrets, garnered by expensive R&D, which comprise a great deal of their income just to please a (let's face it) very small fraction of their installed customer base. Sure, if it was released, the linux community would jump on the code and make a driver roughly a million times better than anything ATI could produce, but realistically I just don't see it happening any time soon for a very good reason.

  14. Re:As they say... on Perpetual Energy Machine Getting Lots of Attention · · Score: 5, Insightful

    We do harness the kinetic energy of the larger bodies of the solar system for practical use. One more obvious use of this is tidal power (generated by slowly affecting the kinetic energy of the Moon, IIRC, and harnessed by small turbines in coastal areas). One less obvious use of this is the planetary flyby technique used by spacecraft. By decreasing the velocity of Jupiter by [insert mathematically insignificant number here], a small space probe can go into a Jovian orbit at one velocity and exit this orbit at a significantly higher one in a different direction while using virtually no fuel.

    I'm not sure what you mean by the "energy storage" with natural magnets and rotational kinetic energy (Remember, the vast majority of ferrous material on this planet, and thus the source of the Earth's magnetic field, is in the core, not the crust), but there are techniques for using the Earth's magnetic field to produce energy. I saw a test of an apparatus on the NASA channel (Now that's good television) which used the spacecraft's movement through Earth's magnetic field to induce a current in a tether outside the spacecraft, which they then used to power stuff on board the spacecraft. But this was still not "free energy", because the magnetic field generated by the current interacted with that of Earth and decreased the spacecraft's velocity and altitude (as expected by NASA engineers and the law of conservation of Energy). This was mostly recoverable, though, because feeding current the other way through the cable increased the spacecraft's altitude again. The only way to get current out of a magnetic field is to move charged particles through it, which is convenient, because everything is made of charged particles. Energy must be expended to get those charged particles in motion in the first place, and once the current has been generated, the kinetic energy of the charged particles drops to zero.

    My point is, even by harnessing the kinetic energy or magnetic properties or what have you of the cosmos, you do affect them in a small way. Try that fly-by trick enough, and Jupiter will fall out of orbit. Some energy in space looks "free", but in actuality it's really just "insanely cheap" energy.

  15. Re:American metric system on NASA Will Go Metric On the Moon · · Score: 3, Interesting

    The conversion from electron volts to Joules is the value of a coulomb, which is another important metric unit in electrical calculations (although "metric" and "electrical" may be redundant; I have yet to encounter english units in circuits). The point is, if you know what a coulomb is (and you should, if you are doing this sort of calculation), you know how to convert between electron volts and Joules.

    Now the english unit for energy, on the other hand, is the Btu. Converting it to the next "logical" english unit is a factor of about 778 Btu in a ft*lbf. Anyone who has taken thermodynamics knows the Btu as an enemy because using it with things like pressure (usually lbf/in^2) and mass flow rate (remember, there are many types of pounds in English, some for mass and some for force) requires inches, feet, and two types of pounds. Now let's try to convert from Btus to electron volts for even more fun! Because english has failed to come up with any useful electric units (even in the US), this calculation gets extra-nasty.

    I suppose my point is as follows: Does the metric system always mesh nicely with physics? No. That's just the way the universe works. FSM made it that way. But some English units just seem to fit together with no rhyme or reason whatsoever! It's as if they made it up as they went along.

Sure, there were fights over it (mainly caused by my sister monopolizing 20 threads at a time serving her AIM away messages while I was on and my retaliation by killing all her CPU-hungry processes and logging her off using root powers). But no one ever got seriously hurt.

    Bad example. My point is that unless one person is a very heavy computer user (constantly using it for work or coding), sharing a desktop until the kids need a computer for college could very well work.
