  1. Stability is needed on Are Altcoins Undermining Bitcoin's Credibility? · · Score: 1

    The programmers need to design a digital Bretton Woods system and enforce a stable exchange rate. For instance, the value of one eMark could be pegged at one five hundredth of a bitcoin, and the various central banks would be obligated to buy and sell bitcoins and emarks at that rate. That way, a miner wouldn't have to worry about backing the wrong computations.

  4. Re:Bragging vs secrecy. on Long-Wave Radar Can Take the Stealth From Stealth Technology · · Score: 1

    From Aviation Week

    It wasn’t hard for the Russians to assess the JSF’s stealth performance. By 1995, everyone knew that shape was the major driver of RCS, with materials being used to control local scattering phenomena. As the JSF’s target service entry date arrived, so did the Russian answer, and it was on display at the MAKS air show, held in Moscow in August.

    The 55Zh6ME radar complex addresses many of the limitations of the old VHF radars. Although you see three radars—stepping down from VHF (metric) to L-band (decametric) and S-band (centimetric)—the Russians call them modules of an integrated radar system. Each unit is fitted with the Orientir satellite-navigation system, which provides a very accurate location and north reference. That should make it possible to provide sensor fusion—ensuring that when two or more of the radar units detect a target, it will show up as one in the control center.

    The VHF part of the system (see photo) has a P-14-sized, 30-meter-wide antenna, but it folds onto an 8 x 8 truck. The antenna has an active, electronically scanned array, so if it gets a hit on a faint target, the array can dwell on it as the antenna rotates (or swings back and forth for a sector search). At the same time, it will cue its L-band and S-band sisters to focus on the target area like searchlight beams.
    Some commentators will look at the Russian brochures, note that the reference ranges are against targets with an RCS of one square meter and observe that stealth aircraft have a far smaller RCS, which they do—in centimetric bands. Giving what was probably the least provocative answer under the circumstances, a Russian engineer notes that the Chinese DF-15 short-range ballistic missile has a 0.002 m2 RCS in X-band, but is a very non-stealthy 0.6 m2 in VHF.

    Two exhibitors at MAKS were showing passive RF tracking systems. They are intended to exploit active emissions from the target but do not discriminate. Scattered energy from a radar will work just as well. The U.S. Air Force does have a modern facility for testing such bistatic radar signatures, but it was commissioned after the JSF was designed.

    Of course, this sort of analysis relies on unclassified data. As the author himself states.

    There may be a universe where it is smart to give your adversaries (or their armorer) 25 years’ notice of exactly how you plan to render their defenses obsolete. We just don’t live there.

    instead, we live in a world where one must have faith that a trillion dollar weapons program has been designed correctly. How comforting.

    As important to a man's self image as the power of his car's engine or his motorcycle's rumble, SCIF size had become a symbol of status.

    Such "dark matter" would show up on Xrays infrared or radio, so that's not a problem. If, however, the "dark matter" does not interact with electromagnetism, but only with gravity and the weak force, (which would be an extremely odd, and frankly, a not very believable aspect of cosmology) things would get a bit tricky.

    The Green Card Lottery is a completely legal program giving away a
    certain annual allotment of Green Cards to persons born in certain
    countries. The lottery program was scheduled to continue on a
    permanent basis. However, recently, Senator Alan J Simpson
    introduced a bill into the U. S. Congress which could end any future
    lotteries. THE 1994 LOTTERY IS SCHEDULED TO TAKE PLACE
    SOON, BUT IT MAY BE THE VERY LAST ONE.

    PERSONS BORN IN MOST COUNTRIES QUALIFY, MANY FOR
    FIRST TIME.

    The only countries NOT qualifying are: Mexico; India; P.R. China;
    Taiwan, Philippines, North Korea, Canada, United Kingdom (except
    Northern Ireland), Jamaica, Domican Republic, El Salvador and
    Vietnam.

    Lottery registration will take place soon. 55,000 Green Cards will be
    given to those who register correctly. NO JOB IS REQUIRED.

    THERE IS A STRICT JUNE DEADLINE. THE TIME TO START IS
    NOW!!

    I guess what the ACLU got their panties in a bunch about is that the organization also acts as a central point of contact for SWAT training/ purchases in the region.

    So... a group of police, are setting their training calendars together so they can have a training session with more people at one time so they can save money on instructor costs. And they are buying stuff in bulk to reduce their costs.

    You seem very intent on minimizing NEMLEC's role. Perhaps you are under the impression that the council is a mere social club organizing get togethers, banquets, golf outings, and dinner dances for men with guns.

    The ACLMU's complaint suggests that this is not the case.

    But if you are correct, and NEMLEC is simply brokering fleet purchases of armored vehicles, enabling the smaller police departments to militarize just as quickly as the Boston Police Department, but with the added savings of buying in bulk, we have nothing to worry about.
