  1. original report is online on Are We Too Reliant On GPS? · · Score: 3, Informative
  2. not the first time on Kilogram Gets Controversial; Why Not Split the Difference? · · Score: 1

    The measure of length called a foot that we use for practical commerce was established in pretty much that way. See the story of the international foot as differed from the different foots which were already in widespread use.

  3. Re:Next time you're at an airport, think about thi on Terrorists Bomb Moscow Airport · · Score: 2

    If you have easy access to explosives, you probably SHOULD be inspected more closely, don't you think?

    Household products are sufficient, so who does not have easy access?

  4. Re:Unclassified on Air Force Blocks NY Times, WaPo, Other Media · · Score: 1

    I think it is more like someone with OCD who can't stop cleaning things. This mentality makes them vulnerable to spend arbitrarily large amounts of effort accomplishing nothing simply by telling them there is a speck of dirt somewhere. It is beyond pedantry to the point of neurosis, if not psychosis.

    the deviation is quadratic, so an hour accumulates 800 to 900 years

  7. Re:The problem with leap seconds... on 'Leap Seconds' May Be Eliminated From UTC · · Score: 1

    Neither are changes to civil time as decreed by local authorities predictable, but zoneinfo manages to handle the problem. If leap seconds went into zoneinfo with the underlying time_t being uniform then the handling of leaps would be in user space, not in kernel space.

  8. Re:Poor solution on 'Leap Seconds' May Be Eliminated From UTC · · Score: 1

    There is no international regulation which specifies either TAI or GPS time, and the agencies which provide those do not want such regulation. For those who are constrained by regulation, only a time scale specified by the ITU-R will suffice.

  9. Re:Poor solution on 'Leap Seconds' May Be Eliminated From UTC · · Score: 2, Interesting

    The reason we adjust for solar time is that two standing international agreements demand that we define the day as a "mean solar day". Computer people and farmers can use different times if mean solar days are not made illegal and replaced with atomic days, that's what zoneinfo is for.

  10. the problem will not go away even without leaps on 'Leap Seconds' May Be Eliminated From UTC · · Score: 3, Informative

    The historical record of time_t is already ambiguous and cannot be corrected by abandoning leap seconds. There is a way to get leap seconds out of the kernel and into user space which amounts to reclassifying them as decrees of change of civil time and putting them into zoneinfo while letting the broadcast time scale not have leaps. It's a matter for posterity whether the word "day" will be re-defined by the ITU-R, changed from the current treaty-specified "mean solar day" to a technically-defined "atomic day".

    He posited execs who had embedded goniometers to ensure that each bow to a Japanese business partner reached the appropriate level. This looks ripe for similar treatment.

    It's not W32Time. It is not possible to regulate the Windows system clock that well no matter what is used to try to do it.

    Microsoft refuses to consider the notion of clocks accurate to within 2 seconds.

  17. now we are six on Decades-Old Soviet Reflector Spotted On the Moon · · Score: 4, Informative

    This means there are now six useable reflectors. See the list from the investigators.

  18. this fee is the price of the insurance on Electric Company Wants Monthly Fee For Solar Users · · Score: 2, Insightful

    There are some solar users with battery banks large enough to ride all the way through a typical night, but very few solar users with enough battery to last through a week of storms. In this case the power company's infrastructure is acting as insurance, and a fee like this is the price for that insurance.

    When did C lose its status as an open source language? or do we mean languages for web apps?

    I sure would like to see the numbers which show how the solid fuel debris velocity compares with the velocity imparted to the capsule by the launch abort system.

  21. Re:Fluctuations? on Leap Second To Be Added Dec 31, 2008 · · Score: 1

    Leap seconds do affect the calendar, but only if you expect that calendar to be good for more that 10000 years. Designing any human system to be good for more than 1000 years is somewhat of a conceit. Then again, designing a human system to fail in less than 1000 years might be given a different sort of apellation. This sort of choice is what the timekeepers of the world are trying to make as the ITU-R debates abandoning leap seconds.

  22. Re:Longer, or shorter? on Leap Second To Be Added Dec 31, 2008 · · Score: 1

    If you're in London, where legal time is still mean solar time, then the legal new year happens in the middle of the UTC leap second.

  23. legally speaking, it's the first leap for the US on Leap Second To Be Added Dec 31, 2008 · · Score: 5, Informative

    Until 2007 legal time in the US was mean solar time, and that has no leaps, so this is the first leap second for the legal US time. Officially, of course, USNO and NIST were keeping UTC, but that didn't make it legal. The difference shows up in computer time scales.

    This looks like the next in the ongoing series of "fMRI results of the week", but I was already quite sure about this without fMRI because I know how the notion of value maps onto the realm of images of women.
