    Correlation does not mean causation. Amen.

    Note that the link given was not to the study itself, but to a newspaper report on the study. Reporters and editors might have butchered the facts. But if it was described accurately, the UK gov't just wasted a research grant.

    What particularly bothered me was all the claims of better skills being "developed". You can support that claim only with a longitudinal study, where you measure the abilities of your test and control groups repeatedly over a period of years. Then, if the two groups had the same scores at the beginning and different scores at the end, you might have actually proved something. If you randomly picked who went into groups x1 (gamers) and x2 (TV-watchers), and then sent a large man out to shadow each test subject and force him to conform to your plan, it probably did. But when the groups are self-selected, it's possible that choosing x1 and developing more y are both due to z, which you don't know enough to measure. And in a cross-sectional study (that doesn't follow the subjects over time), choosing x1 was quite likely related to having more y in the first place.

    For example, although it's not surprising if shooter-type video games improve eye-hand coordination, merely showing that gamers average better ehc doesn't tell you whether gamers developed that from gaming, or the uncoordinated just bombed out of the games and went back to the boob tube. To me, showing that moderate video gamers go out for sports more makes it seem likely that they were better coordinated to begin with. (E.g, terrible coordination kept me out of sports as a kid -- and if video games had been invented, I don't think I'd have been racking up the record scores. D&D, in the original text-based version, was a game I really could get into -- but I was too adult by then to have the free time.)

    As for intelligence, it's obvious that smart kids select challenging entertainment, while boobs prefer to watch the boob tube. It wouldn't be suprising if it also works the other way around (games increase intelligence) but you can't prove it either way from just a correlation. Likewise, video games quite likely increase your ability to concentrate, but you'd see the same correlation if people who couldn't concentrate didn't play the games.

    So this really doesn't say anything that a reasonable and unbiased person wouldn't have guessed in the first place. The only reason the authors (or perhaps just the reporter?) seem surprised is that they were biased against "geeks" going in. This report, devoid of real information as it is, might help dispell that prejudice. Bookmark it and beat the geek-haters over the head with it regularly -- they're too dumb to see the flaws, right? 8-)

    Depends. One man pounding on an armored car is little danger (except possibly to the re-painting budget). One hundred are a danger. I didn't get a good view of the vehicle, but police riot vehicles are generally not tanks, they are just trucks with extra heavy sheet metal and window glass.

    Paying your debts is morally imperative. Giving away the money that might have paid part of the nation's debts is something else...

    Actually, I'm enraged by your claim to "moral" imperatives, but on practical grounds, sending out the $300 checks as an advance on a small tax cut next year is the one intelligent part of the package. We've for once in history got the luxury of a substantial surplus (projected), but if we DON'T use part of it to keep the economy going, the surplus will evaporate as incomes and tax revenues fall. According to economic theory, releasing this money _now_ should help keep the current economic blip from turning into a deep recession. (Or worse -- the stock market hasn't become so overinflated or dropped so hard since 1929... But I think federal and state gov'ts helped turn that crash into the Great Depression by initially raising taxes to cover increased welfare bills -- even FDR initially tried to keep a balanced budget in 1933. Doing the opposite as early as possible is just good sense.)

    But in the long run, the surplus has got to be paid off. It's a pipeline that takes several hundred billion dollars a year in interest payments from ordinary Americans and into the pockets of some of the richest Americans. Paying it off as soon as possible is the right thing to do, and the smart thing to do. The majority of W's tax cut not only jeopardizes paying off the surplus while kicking in too slowly to help with the present economic slowdown, but it's also ridiculous on its face. Cut the estate tax for ten years, then bring it back? Make college tuition deductible for just four years?? (Does that have anything to do with the fact that W has twins in college right now???)

    The one good counter-argument is that, judging by history, if the money is available, Congress will spend it. (And if the money wasn't available, they'd spend it anyhow.) With a (mostly) Republican congress and president for the first time since Eisenhower, "smaller government" now being the Republican mantra, and no Cold War to suck up the cash, things really ought to be different. But I think that history has shown that no matter how much Rep. voters want smaller gov't, the people who win office on that ticket really don't want to shrink their own roles... BUT, there was one sensible suggestion made right at the beginning of the congressional session: tie tax cuts to paying down the debt, so any vote to spend more would automatically be a vote to tax more. It wasn't the Dems that shot that down.

    What I want is for them to cut spending A WHOLE LOT, kill entire gov't departments (Education, HUD, DEA, BATF, and about 3/4 of the EPA, DOE, and FBI just for starters), slash taxes an equal amount, pay off the debt, and then we can really cut taxes. But you can't always get what you want...

    But the RIAA did not bring a false suit, they only threatened to bring a false suit. That isn't barratry. Sending unfounded threats of lawsuits is a kind of harassment, intended to either frighten someone out of doing something he or she is legally entitled to do, or to cause him or her to expend time and money consulting a lawyer to determine if there is any foundation to the threat. I don't know of any law specifically allowing collection of damages for this (IANAL), but there ought to be one -- I'd suggest a right of the recipient to demand a show-cause hearing, a simple fixed fee (say $5,000) if the sender defaults by not showing up in court to demonstrate that the threat is founded, while if the sender does fight in court and lose, the recipient gets all legal fees plus damages.

    If they can't get the toothpaste back in the tube (i.e., if they can't recall ALL their binaries which violated the GPL), then they should have to release the offending source under the GPL. Wrong. The most a court could order them to do is to pay damages and stop infringing the copyright. (In other words, if you sold 1 million copies of a pirated Disney video, they don't make you go get those tapes back, but rather you've got to pay Disney for the sales they presumably lost -- and that's probably more than your gross revenue from the tapes.) Since you can't lose revenue on free software, in this case the cost would be the "statutory damages", which I've been told are now $100,000. I think that would pay _part_ of the cost of going to court. So once Vidoma has ceased infringing, filing suit would just enrich the lawyers.

    On the other hand, if Vidoma really wants to be sure it's over, they should offer each of the authors something (say $1,000) as a settlement in full -- otherwise it would indeed be possible for one of them (if he's rich enough) to sue for those damages.

Since they are no longer infringing, taking them into court over past infringement would be a lose-lose proposition. Since there is no lost revenue, the best that could happen would be getting the full statutory damages, and the lawyers would take that to cover their expenses and ask for their fees besides...

    However, I would have held out for a symbolic $1 damage payment also, just to establish that Vidomi recognized that they had infringed copyright.

    The thing is, the congresscritters are already skilled at writing tax breaks so that they turn out to apply to just one corporation. So if you don't watch them really closely on something like this, they'll construct the specs so that only one company currently has a product that qualifies, and maybe they've got patents that ensure nobody else can design anything to meet those specs. Not that in this case it is hard to write performance-oriented specs that are simple, attainable, and don't favor any one company, but how does a congress-critter repay his, er, contributors that way?

    The specs I'd use for the machines:

    --Leaves a hard-copy trail, so it is practical to manually spot-check machine counts, and to hand-count in a disputed election.

    --Proven error rate in recording votes as marked: 0.5%

    --Proven error rate of a random sample of people in marking ballots as intended: 1.5%

    --Secret ballot.

    --Minimal use of absentee ballots. You can't pre-vote everyone who asks for an absentee ballot (e.g. someone serving overseas in the military), but do pre-vote whenever possible.

    --Use the best systems available to check registration lists before elections and to ID the voters on election day. Like, have a computer cross-reference the registration list to the death certificates, for crissakes.

    --Provisional voting procedure in place to deal with disputed voters (missing from registration list, questions about ID, etc.): You put the ballot inside a plain envelope, put that inside another envelope with the voters alleged name, etc., and after election day you figure out which ballots are valid and count them with the absentee ballots.

    --Uniform hours, long enough that everyone gets through. Never shut out people who were standing in line an hour before closing.

    --Manually spot-check the machine counts

    --Full hand re-count required if the election is within the error bars in recording votes as marked, or if machine problems are discovered. This is not something the candidates have to ask for. You owe it to the _voters_ to count the votes right.
