    Yup, and to further convolute things, the wireless specific implementation of this is 802.11e

  2. Re:But it doesn't scale on NASA's Flying Wing Breaks 2 Records · · Score: 2

    Sure - building it out of the same materials would screw up the scaling, but if I remember correctly, there have been one or two breakthroughs in lightweight materials at NASA ;)

  4. Error Correction? on CD Copy "Protection" in California · · Score: 4

    The article says that CD-player error correction overcomes the introduced garbage, wouldn't a CD-ripper's error correction ability be able to overcome this as well? Even if current software rippers can't, it doesn't sound all that hard to deal with...

  5. Re:Could prove useful on Solving the Great Shower Curtain Mystery · · Score: 2

    The Rincon Center in San Francisco has a large waterfall/shower thingy in the middle of it's indoor courtyard. In addition to being attractive and providing a soothing background noise, it is also said to lower the temperatur in the immediate area by 3-4 degrees (if memory serves). This isn't due to any 'hurricane' effect though, it's simple evaporative cooling (a'la swamp coolers, or those cooling 'water bongs' that overclockers use to replace radiators).

  6. Re:Finally! A believable answer on Solving the Great Shower Curtain Mystery · · Score: 3

    And how does it explain airplanes successfully flying upside down? A more plausible answer(to me anyway) involves the angle of attack the wing makes. Air is forced downwards and by conservation of momentum something must be forced upwards - the plane

    You're trying too hard here, why can't you both be right? Planes that fly upside down do not do so indefinately, and require a greater amount of thrust and angle of attack to overcome gravity and 'reverse lift' than an aircraft in normal flight. They also are incapable of maintaining a constant altitude during inverted flight, with few exceptions (trust me, I used to fly stunt planes, it's not as simple as it appears).

    Basically, when inverted, the angle of attack is changed such that the 'reverse lift' (downward force generated by pressure differential) is minimized as much as possible, at the same time allowing some thrust to be converted to lift (by pointing the prop/jet output slightly down). This is basically the the 'kite' type of flight that you refer to.


    Now, about those exceptions - aircraft capable of producing enough thrust to overcome gravity without the help of lift are often known as rockets, or in some cases military aircraft. Take a Mig27, with ~40,000lbs of thrust and wighing only ~30,000lbs, the wings are almost superflous, however they still remain, primarily as control surfaces, and efficiency aids (fuel goes fast when producing enough thrust to throw a 20 ton mass directly skyward).


    I know it seems a tad illogical at first, but get a good hands-on book on flying, and try some of the experiments, you'll be amazed at what is proveable....

    _If_ the source is even available, it'll be under MS's shared source program, and likely include such wonderful EULA provisions like banning the use of GPL'd software in conjunction with it... Why would they 'legitimize' Free software after spending so much time trying to stop it's 'viral' influence?

    Every time I read an article about a limit in some area of computing (network speed, storage, CPU speed, stupidity of A. Grove), it seems as if it's the last sign that a new method/paradigm is on the horizon, with a significant breakthrough coming.

  14. Re:Mach 3 Bumble Bees on Stealth Aircraft Useless? · · Score: 3
    Sorry, but your argument here is full of holes. First of all, we don't have a stealth bomber that goes Mach 2 (the -22 isn't a true stealth plane, it's just 'stealthy'). Second, the radar returns from a stealth bomber are highly variable, and wholly inconsistent, dissapearing, re-appearing, shifting, and then dissapearing again. A single object travelling ~800 knots would stand out, however a stealth bomber wouldn't appear as a single object, rather a series of seemingly unrelated, extremely small objects - ie. noise.

    Now, at close range, with a known location, a good RSO could probably pick out a stealth bomber with fair accuracy, but how often do we tell our enemies exactly where we are going to be and then fly right over their radar installations? That would kind of defeat the purpose....

    1) RB wrote the exact same thing in the forums over a week ago.

  17. Hunh? on AOL/Microsoft Talks Break Down · · Score: 5
    AOL has too much to lose if their software isn't pre-installed, it was their key to success in the first place.

    AOL was succesful long before it was pre-installed on any OS, and MSN was pre-installed on an OS before AOL, yet it doesn't have 25 million subscribers... I'm not saying preloading hasn't helped them, but to give it all the credit for their success is going too far. No, for that we have to give credit to the limitless stupidity of the public at large...

    I worked for a company that serviced a few hundred small offices' networks, many of which were based on NetWare. It was not at all uncommon for us to visit clients with 1-2 years of uptime on their servers, 3+ years wasn't unheard of.
    We had to be really careful with these long-life boxes if we ever had to restart them though, because every once in a while the hard drives would just not spin up. The motor worked fine for keeping the old girl going, but it was no longer able to get it going...

  22. Stolen my ass... on TiVo Usage Info Collected For Sale · · Score: 3

    First of all, this is pure speculation, TiVo had said publicly that they will NOT be doing this - the space is for Video On Demand PPV stuff. Imagine your TiVo knows you love Natalie Portman movies, well the next time one is available on PPV, TiVo will store it for you (locked up) and allow you to watch it on demand for a fee. It's basically time-shifted PPV movies.
    Second, there is no 'stolen' disk space... All TiVos have space reserved on them from the factory, the higher the capacity of the machine, the more space there is. The only change is that with the 2.0 upgrade, people who hacked their TiVos had their reserve space adjusted to reflect the higher capacity of the box. Considering that TiVo has been very tolerant (even helpful at times) of people hacking their boxes, and this only happens to hacked boxes, and TiVo has been warning people about this for ages, I would find it very hard to use a strong term like 'stolen'.

    Think long and hard about what's more important - the Freedom of Open Source Software, or is it the software itself? If the former, we must disregard any possible negative impact on the latter...
