    Yes - but they are effectively patenting all methods of doing this. And that is the big problem. Amazon didn't patent one particular method of providing one-click shopping, they pretty much patented them all. As such, Microsoft will have a lock on anyone doing verb conjugation on a computer.

    Nowhere in this patent do they describe the method in anything but the broadest generality - they are not patenting a specific implementation (which is what covers programs under copyright law).

    As you imply - it's not unusual but it's still a bad idea to allow method patents like this.

  9. Re:A game theory angle on You Have Been 'Randomly' Selected? · · Score: 1

    On international flights to the US passengers pass through a second security check where their carry on luggage screened a second time and they are subsequently segregated from other travellers (at least from Australia). I believe it is a US requirement aimed at minimising the possibility you talk about. Domestic flights in the US obviously have different security arrangements.

    Having travelled with children I can also say that there is nothing sacrosanct about babies to security screeners. We had to pass our baby daughter through the metal detector by holding her in our extended arms. You can't hide anything in children's clothes.

    But, more abstractly, the same principles continue to apply. I would think that mothers with young children would still have a relatively high aversion to even being involved in terrorism so they would still be 'low risk' and optimally subject to a lower probability of search.

  10. A game theory angle on You Have Been 'Randomly' Selected? · · Score: 4, Insightful

    You can think about it in terms of game theory.

    An important concept in game theory is the mixed strategy. That is where you randomise over certain choices because it is optimal to do so to prevent your pattern of play being anticipated and counteracted by your opponent. (Consider a game of matching pennies - you choose heads or tails and reveal it simultaneously to your opponent. If they match you win, if they don't your opponent winds. The optimal strategy is to randomly pick 50/50 heads and tails. Skillful players of games in general are ones that can a) randomise themselves properly, and b) exploit the fact that their opponents don't randomise properly)

    Thus, in the case of 'random' searches it needs to be random to ensure that the searching strategy can't be circumvented. But that doesn't mean that the odds of every given person being selected need to be the same. For example, if it is much harder for terrorists to convince mothers with young children to become scuicide bombers that means that they are less likely to do so or, completely dispasionately, if they do there will be fewer terrorist attacks because they have fewer volunteers. This would still be better than the alternative. Importantly, for the discussion here it is provably optimal to do this.

    Thus, an optimal screening strategy is random, but the probability of selection need not be uniform.

    (And a statistics aside: even though the chance that someone who flies 4 times gets selected every time would seem to be 1/10000 - if they individual odds are 1/10 - given that over 10,000 people fly, you are almost guaranteed that someone will be selected 4 times in a row.)

    Much as I would love to get into a 'my uptime is longer than yours' and 'I once saw a Windows system run for a whole week without BSODing' debates, the point here is about the behaviour of users.

    Sure you can avoid rebooting on a Windows system - but the majority of users don't. They have been trained to act this way by the flakiness of Windows and the interminable lags that BIOS imposes on them (especially in laptops) so that, even when those problems have been overcome, they still shutdown and restart. Mac users, on the other hand, have taken advantage of the fact that their laptops startup from sleep more quickly than they can raise the laptops screen and don't have memory problems that kill their systems over time.

    Sucks to be a Windows users doesn't it?

    One of the fundamental differences between Mac laptop users and Windows laptop users seems to be the frequency of booting up. Mac users invariably shut their computer's lid to put it to sleep. Windows users seem to have this habit of shutting it down and then starting up again. I've heard rumours that it has something to do with the difference between BIOS and OpenFirmware/EFI and the interminable wait you face to wake a Windows laptop from sleep - I wouldn't know.

    But OS X users don't restart their computers, so the point is moot.

    I rarely shut down my MacBook Pro or the Powerbook I used before that - I just put it to sleep by closing the lid and open the lid the next time I want to use it.

    I only have to restart because of the occasional system software update that requires a restart. Otherwise I'm golden.

    How can they claim that there is any meeting of the minds or that all terms in the contract were fully understood by the 'employee' if it comes up in court later. Can the employers insist that you sign it without giving you time to properly review it (even without a lawyer)?

    Because I would consider an employer insisting I sign a contract and denying me the opportunity to review it an abusive employer. But moreso, such conduct would seem to render the contract unenforceable. Can such employment contracts signed under such conditions be upheld by US courts?

  20. Re:Free money on Apple Recalls 1.1 Million Laptop Batteries · · Score: 1

    A charge cycle is 100% of battery usage - however distributed. It doesn't have to do with the charge displayed in your menubar and a charge cycle can click over at any level of charge.

    For example: Use 20% charge down to 80%, recharge, use 10%, recharge, use 70% is one charge cycle
    Another example: Use 5% twenty times is one charge cycle.

    What I think you demonstrated is that prior to unplugging it the first time you had used 99% of a charge cycle. It should take a further cumulated 100% before you click over to the next charge cycle.

    Apple's power management means that it doesn't start to recharge until you drop below 95% charge. The first time you were at 93% and it started recharging (orange light), the second time you were at 99 and 98% so it didn't start recharging (green light). It does this to minimise the number of small charge cycles and thereby maximise battery life. (Lots of 1% charges could do bad things to your battery it would seem.)

    Do that again and see if it goes to 666 (!!!). I expect that it would stay at 665. As such, your experiment hasn't proved anything yet.

    You should find that it is actually cycle count rather than the number of times it's been plugged in. I have a brand new MacBook Pro battery that has 1 cycle on it. It has been plugged and unplugged a number of times (>1) but only used for short bursts in those periods so it hasn't yet got to the full discharge to click over the cycle count.

    I have used Spotlight realtively regularly and like it a lot.

    By far the most useful for me is lyric searching. I have used pearLyrics to add the lyrics for most of my music collection into my iTunes library. I can search through all these lyrics using Spotlight to rapidly find out, for example, songs that use the word 'walk', 'swim' or 'avocado' - or even the ones that talk about swimming and avocados. This is really useful when choosing the right piece of music to use as a soundtrack for my home movies.

    But its also useful for tracking down particular phrases that you aren't sure which document they are in.

    The thing that makes it particularly pleasing to use is its speed. It is real time. It will be completed by the time I finish typing the query in. Windows search is just a nightmare - I just give up because I can't wait for it to finish.

    But, hey, if you know the lyrics to every song ever written and everything you have ever created - more power to you. You should go on one of those TV shows they have for people like you.

    It's a pretty standard finding. Bidder strategies will adjust to any changes in auction formats.

    Standard English auctions, Dutch auctions, first price sealed bid auctions, second price sealed bid auctions all end up at pretty much the same price - they just get there by a different route. But English auctions (as well as second price sealed bid auctions) generally have the advantage of truthful revelation of valuation by the bidders.
