  1. Re:Waste of time... on Video Tape Recorder Unveiled 50 Years Ago · · Score: 1

    Don't confuse consumer grade tape machines with commercial grade tape machines. When you pay $100K for a tape machine, you get something with much better performance, consistency and reliability, that can be used for decades with periodic overhaul of the recording heads. I know people who use tape machines that were built 20+ years ago on a daily basis. These "ancient" machines still meet specs and rarely break.

    Simple concept? No, it isn't. Transverse recording is a major jump in technology from longitudinal recording. It enables head to tape speeds far in excess of that possible with longitudinal recording. It requires a complex rotating head assembly and very close attention to tape handling. A friend of mine used to use one of these beasties, modified for improved performance, to record image data from the LANDSAT-1 satellite. It was the only tape machine that could do the job.

    Maybe they might get more sympathy from the West if they took more responsibility for their own actions. Most African governments are corrupt and incompetent jokes. You can't blame everything on colonialism forever.

  4. Configuration Control on Border Security System Left Open · · Score: 4, Insightful

    Because in large and complex systems, you don't install patches until they have been tested for unintended side effects. That may mean scheduling, running and evaluating some very complex tests. This can take weeks or months, depending on budgets, priorities, and operational commitments.

    Take German war memoirs with a major grain of salt. They often take credit for all the smart decisions and blame Hitler for all of the mistakes. They also often have large gaps where they decided not to write about their involvement in politics or possible war crimes.

  9. Stolen Property Registry on Wifi and Laptops Adds Up To Theft · · Score: 4, Interesting

    I'd like to see the creation of a publicly accessable stolen property registry, to make it harder for thieves to sell their loot. Auction sites, like eBay, could require sellers to list the serial numbers, if any, of all items that they are selling.

    It violates federal law, which trumps state law. Specifically, the privacy act of 1974

    Wrong. The Privacy Act of 1974 only applies to the executive branch of the federal government.

  12. Re:Same Problem - Really Expensive Speakers on How to Avoid Mobile Phone Interference w/ Speakers · · Score: 1

    Any active electronics, like amplifiers, should be in a shielded enclosure. In addition, add RF filters to every point where a cable (power, signal) enters or leaves a shielded enclosure. This sort of thing is standard for commercial grade equipment, but often missing on cheaper stuff. Shielded cables can also help prevent problems.

  13. Re:GSM on How to Avoid Mobile Phone Interference w/ Speakers · · Score: 3, Informative
    Yes, it does. You have to distinguish between TDMA (the technique) and TDMA (the standard, D-AMPS or IS-136). Both GSM and IS-136 use TDMA (the technique).

    See TDMA.

  14. MFLOPS/W on Junk Super Computer Assimilates All · · Score: 1

    What's the optimal CPU for MFLOPS per watt these days? At some point, an old system is just too slow to justify the power bill, when a cheap new system delivers much more performance at minimal cost.

  15. GSM on How to Avoid Mobile Phone Interference w/ Speakers · · Score: 4, Insightful
    It seems to largely be a problem with GSM handsets, so users of handsets that comply with other standards may not notice a problem. GSM uses TDMA, and has also been noted for interference to hearing aids.

    The solution is to properly shield the speakers and speaker wire. The speaker wire behaves like an antenna, coupling the signal into the audio amplifier, where it is detected and amplified. It's behaving like a crystal radio, a primitive type of AM radio receiver.

  16. Re:Careful... on IRS Leaves Taxpayer Data Largely Unprotected · · Score: 1
    It's for this reason that I've never understood why governments don't set the tax services (I don't live in the USA; We call the equivilent of the IRS the Inland revenue, there's no service about it on this side of the Atlantic.) onto "Teh Terrorists!!!"

    Actually, they have. There was a recent article on how Kim Il-Jong is in a world of hurt because the Treasury Department, with a lot of international cooperation, has been investigating and shutting down North Korea's illegal sources of income and goods. Banco Delta Asia, a large bank in Macao, became the international banking system's leper after the Secretary of the Treasury made a finding that it was a "financial institution of primary money laundering concern". It had been deeply implicated in questionable and illegal practices on behalf of North Korea.

  17. Re:Not quite on The Software of Space Exploration · · Score: 1
    Opposite of what?

    The contractor initially has the copyright, since he is the creator of the work. The work, and its associated copyright, are then delivered to the government. That's for software written to the specifications of the government, when the government pays for the labor. If the contractor wants to keep the copyright, he can pay for the software development out of his own pocket. I've seen that done when the contractor thinks that the software may be a viable commercial product. It has to be done off-site, without any use of government resources, such as computers, office space, etc.

    Money. When the Apollo program was shutdown, most of the money for lunar research also disappeared. That resulted in huge amounts of telemetry data and large numbers of lunar samples that were never properly analyzed.

  19. Re:Why not public domain? on The Software of Space Exploration · · Score: 1

    It depends if it is written by a civil service employee or a contractor. Most NASA software is written by contractors. The contractor has the copyright, which depending on language of the contract, can be assigned to the federal government.

    What do you think keeps the Earth as warm as it is? Reactor waste.

    The primary energy source of Earth is radioactive decay. The sun, gravity, and meteorite impacts all contribute some energy, as well, but not nearly as much as that provided by radioactive decay (estimated for the bulk Earth at around 6.18x10-12 watts/kilogram).

    Afterall, that's why DARPA came up with the idea for the Internet in the first place: If one communication link gets taken out, there are still other links to communicate with.

    No, and it wasn't designed to survive a nuclear war either.

    The ARPANET was designed to allow researchers to communicate and share resources.
