  1. Re:Oh, come on on Apple's IPhone 3G Firmware Update Bombs · · Score: 1

    Then how does Virgin Mobile make money? You can get a good phone for 20$. Everything else is fluff.

  2. Re:So what's next? on The US Swim Team's Secret Weapon, Science · · Score: 1

    I know your kidding around, but it gives the swimmers in the middle an advantage over the ones on sides if they have to deal with turbulance.
    Really the empty side lanes were added in the spirit of fairness.

    Fair enough-- do you have the best option available? You can get 5MB up dsl here in albuquerque.

    Internet seems fine to me. Why the obsession with 'higher speed internet'?

  5. I think the question is this on OpenGL 3.0 Released, Developers Furious · · Score: 1

    Is the end of interest in cutting edge 3d? It seems like most of the low hanging fruit in 3d graphics has been picked.

  6. Direct solar heating on NASA Plans Test of New Plasma Drive · · Score: 1

    Another option would be to pump the plasma with solar power directly; a gas like CO would be a good candidate. You can get temperatures of over a million degrees.

  7. Re:Engine? on NASA Plans Test of New Plasma Drive · · Score: 1, Interesting

    I know this technology is in its infancy but beaming microwave energy to an antenna might work.

  8. Re:plasma exit velocity? on NASA Plans Test of New Plasma Drive · · Score: 5, Informative

    From wiki:

    Current VASIMR designs should be capable of producing specific impulses ranging from 3,000 to 30,000 seconds (jet velocities 30 to 300 km/s). The low end of this range is comparable to some ion thruster designs. By adjusting the manner of plasma production and plasma heating, a VASIMR can control the specific impulse and thrust. VASIMR is also capable of processing much higher power levels (megawatts) than existing ion thruster electric propulsion designs. Therefore it can provide orders of magnitude higher thrust, provided a suitable power source can be provided.

    radio heating scales (up) much more easily than ION thrusters.
    Google 'microwave plasma balls' and you will get the idea.

    Uh, Chemist? But even a cursory search on google backs up my assertions.

    lightning is a huge source of fixed nitrogen (as nitrate) which starts out as nitrogen oxides.

    Once again it's scientists vs /.ers pulling things out of their *ss.

    Compared to nitrogen oxides they are.
    The fuss over this is as stupid as a scientist making the statement "catalytic converters convert carbon monoxide into harmless carbon dioxide" and then people jumping all over them about global warming.

    Stupid.

    These nitrogen oxides will eventually end up as nitrates anyway, the TIO catalysts just speed this up. Or would you rather that people and wildlife breath them into their lungs first?

    Stupid.

    Nitrogon oxides eventually end up as nitrates, the TIO just speeds up the process.

    Perchlorate is a good source of oxygen, all you need to do is heat it up.

    AHHHH.... this is how government accounting works! If you want a new department, you submit it to next years budget!

    Sure there's a way to add people in the middle of the year, but I bet it is very labor intensive.

    Nice, now put that throught the mandated design process, and run it by the auditors.

    In the entire life of this COBOL program, it probably has not be 'started' in the middle of the fiscal year. How do you do something like this in such a way to satisfy your auditors? I think there are many /.ers that don't have much experience working on large government systems.

  21. Re:Not as lame as people are thinking... on California Can't Perform Pay Cut Because of COBOL · · Score: 1

    All the raises and salaries are designed to be changed at the beginning of the fiscal year. The system probably creates each pay stub in advance... and then the total budget calculated.

    Just guess but the system is not designed to be adjusted in the middle of the year.

    Actually the way this works is that the toothpaste scratches the surface in such a way that the laser focuses the beam more precisely. When focused perfectly the laser is more likely to miss scratches.

  24. Re:Coaxing vs Pushing on Gravity Tractor Could Deflect Asteroids · · Score: 1

    Not to mention that crashing will require less fuel because the sooner you push the asteroid the more time it has to move out of the keyhole. It will require less sudden push than a small push over a period of time.

    It makes sense from a security perspective; there are plenty of legitimate activities such as online banking that you would not want to keep records of on the machine.
