  1. The entire timekeeping system for the world is based on the definition of 12:00:00 GMT (aka Zulu, aka UTC) as the time when the sun is directly overhead at the Greenwich Observatory in Greenwich, England. Hence Greenwich Mean Time. Arbitrary? Perhaps. But recognized by every standards body on the planet. History, my friend.

  2. Re:That makes zero sense on Mitsubishi Electric Believes Its AI-enhanced Camera Systems Will Make Mirrors on Cars Obsolete (ieee.org) · · Score: 5, Informative

    Anything beyond about 20 feet is essentially at infinity focus. What is lacking in cameras is depth perception. Try driving, or backing up, with one eye covered (caution). It's surprisingly difficult to do confidently. Until they figure out how to do 3D cameras and displays in cars, they won't replace mirrors in functionality.

    Or maybe just change our mind-set to do everything one hour earlier. There is nothing that requires our workday to begin at 9:00 am, so just adjust business hours. Granted, eight to four is not as catchy a song title, but hey...

  4. Depth perception? on Japan Says Yes To Mirrorless Cars (carscoops.com) · · Score: 1

    Are these rear view cameras going to be 3D? Has anyone even considered the disadvantage of losing any depth perception to the flat, 2 dimensional presentation of a video screen? I have trouble imagining the difficulty this would present in a backing situation. With a mirror, you can get a sense of depth and perspective to judge distances. A camera would just give a flat, detached representation of what was there. And perspective would be dependent on the focal length of the lens, among other things.

    Use a moderate amount of rubbing alcohol to help get the water out AFTER you flush with copious amounts of deionized (as opposed to distilled) water. As a chemist, I have cleaned up sensitive electronics that have had potentially corrosive vapors condense on them by washing thoroughly with high purity water. The important thing is to remove the ions that will be in the dirty water. Then, yes, try to remove the clean water as much as possible in a reasonable time. Rubbing alcohol will kill the surface tension of the water, along with the mold, and help the droplets of water flow out. Unfortunately, all available rubbing alcohol contains a large amount of water, so you will still have to wait until that evaporates. But deionized water should not cause any further damage to the electronics. But make sure the label of the water bottle indicates deionization - distilled water can actually still contain a fair amount of ionic material because it is done so poorly. But some "Distilled Water" will indicate "purified by deionization" in the fine print.

    Every rebate I can remember sending in required that the UPC be cut from the original package and sent along. That would immediately either make the item unreturnable, or indicate that the rebate was being collected so it would be deducted from the return. (Not ever having tried to return one, I'm not sure how it was handled, but it certainly made it impossible to game the rebate.)

    Think quantum mechanics/quantum probabilities. 'Tunneling' is a very real possibility. Electron tunneling is widely used in electronics.

    My thinking is that the palladium matrix is somehow modifying the quantum probability functions such that when the matrix is sufficiently saturated with deuterium nucleii, it allows superposition, which gives rise to fusion. I actually came up with this explanation years ago when some people had success and others failed, now it turns out there may actually be evidence to support it.

  11. Re:Drug dealer tactics... on Why Software Piracy is Good for Microsoft · · Score: 1

    Seems to me this is exactly how Microsoft got the market share in the first place. I can remember that early versions (e.g. 3.1) were completely copyable. You just had to find somebody with the distro and have at it. Sure, MS made noises about it, but it was fairly well understood that they knew that anything that got Windows on more desktops would be good for them in the long run.

    With each release since then, they have made it harder to copy. Win95 was no problem if you had the CD, Win98 had the distro in a directory on the HD, but often no CD. The installations of WinMe that I've seen have "recovery CD's" that are specific to the hardware and return the machine to its original configuration, etc. XP requires you to "phone home" to register, and Palladium is on the horizon. It's a steady progression.

    Microsoft used the tactic to get their monopoly, and they will certainly continue to use it to maintain the monopoly.
