    You must have been looking at January 2007.
    All four agencies that track Earth's temperature (the Hadley Climate Research Unit in Britain, the NASA Goddard Institute for Space Studies in New York, the Christy group at the University of Alabama, and Remote Sensing Systems Inc in California) report that it cooled by about 0.7C in 2007. This is the fastest temperature change in the instrumental record and it puts us back where we were in 1930.

    If this trend continues, will we be told to burn more fuel to bring the climate back up to "normal"?

  4. Really Re:that's actually a good solution on Spam Filtering For Small/Medium Business? · · Score: 1

    1 persons vs everyone losing 30 minutes per day? Far out.. there are alternatives.

    We use SpamSentinel (a Lotus-Domino-only product). It's centralised and self-serve at the same time. SS has multiple engines; anything tagged by more than one engine is immediately dumped (now rejected at SMTP). The "maybe"s get quarantined, and users get a daily list of their quarantined items with hotlinks directly to the quarantined messages. From there it's only 1 click to release, or to whitelist the sender.

    I say self-serve is great. It takes me about 5 seconds to scan my daily list (of 20-50 "maybes"), and I've got a better chance of recognising my own legitimate mail than someone else does.

    Surely there's something like this for non-Domino folk.. surely..

    Serifs help find the ends of strokes, which is good for bulk reading. With low-resolution displays, however, it becomes impossible to do serifs properly - they become additional strokes that the brain has to then interpret as a more complex character.
    A few years back someone in the linux distro world knew the wisdom of serifs but missed the point of scale, and we got a lot of ugly and unreadable text under the guise of smallish Times Roman.

  12. Re:a serious response... on What Font Color Is Best For Eyes? · · Score: 1

    The brain is also lazy.
    Your daytime vision senses 3 colors through 3 sets of cones - red, green, and blue. (Apparently some people also have yellow cones and find RGB devices like TV look terribly fake).

    You would have heard advice against red on blue, blue on green, etc. AFAIK that's because each set interprets writing as light-on-dark, or dark-on-light. Red writing on blue background means your red vision sees light-on-dark while your blue visition sees dark-on-light. It's easier on the brain without this contradiction.

    All those white pixels and F's waste energy! How about #CCCC00 on #CCCCCC, or #333300 on #333333? Unless it's an LCD, in which case the dark pixels are converting light to heat. Whether that's a waste depends whether you have other equipment trying to heat or cool the same environment.

  15. Re:The Earth is 6000 years old on Huge Hydrogen Cloud Will Hit Milky Way · · Score: 1

    Only since you asked, seriously...
    Some who believe in "6000 year old earth" claim that the universe started with a white hole rather than a big bang. The sole difference is whether the universe has a size, and therefore a middle, or is infinite and the "bang" happened on an infinite scale immediately. (Curiously, when you ask people to describe the big bang, they usually describe a white hole). Both concepts are equally supported by the same theories in physics. The question of size is an assumption.

    If the start of the universe was a white hole, then there was immense matter density during the early stages. This means immense gravity, which means slower time. Same rules of physics. During the blast of a white hole, the outer reaches may travel for many orders of magnitude more "time" than the inner areas. Should our galaxy be anywhere near the middle of the universe, it could well be orders of magnitude younger than the universe's extremities.

    UTP installations require a licenced/registered cabler in many countries, and for good reason.
    Fibre optic often comes under related rules, due to its own hazards (mostly related to laser light that may be transmitted).

  17. Re:What about leap minutes? on Vote To Eliminate Leap Seconds · · Score: 1

    That's the point. The most-precise reference clocks get adjusted, but they don't do anything with the time other than state it.
    The systems that couldn't take leap-minutes and leap-hours can't do leap-seconds either, but they cope by having slightly longer seconds for a while until they're back in sync. That works as they can tolerate being just that little bit out, and nobody (and no other system) really notices as network traffic incurs delays in the same order of magnitude.

  18. Re:What about leap minutes? on Vote To Eliminate Leap Seconds · · Score: 1

    Nup.
    Really really fancy high-precision clocks already cope with leap seconds.
    Simpler medium-precision systems can cope using a variable skew so the leap seconds are absorbed over a longer period (say, hours).

    To remove leap seconds and create leap minutes or hours means all kinds of systems having to cope with such rare time events explicitly - virtually anything that stores times, implicitly including journalling databases and file systems. It's different to Daylight Saving, where UTC doesn't change, just the offset relative to UTC.

  25. Re:Bullshit on EDGE Can Out-Perform 3G; Here's Why · · Score: 1

    Yup, mostly.
    UMTS is arguably more power efficient, and actively manages the spreading codes and error correction ratios as required. Acknowledgements are retransmissions are incredibly fast - effectively "immediate", so packet loss is just not an argument.
    HSDPA uses more power because the radio must be continually active and listening - it can receive notice of a packet at any time. When HSDPA is not active, the radio and its decoder can shut down most of the time, knowing there are specific times to listen.

    Latency is also improved by structural changes in the back end of provision of UMTS and HSDPA c.f. GSM.
