Which nobody, it seems, but the EU regulators wanted- maybe 2000 of them were sold, ever. OEMs continued to purchase and sell Windows versions with media player bundled, and they still do.
    If Microsoft was smart, they'd go pre-emptive in the same vein and make a SKU of Windows called EU edition, or Antitrust edition- and it'd have the kernel, maybe a shell, and pretty much jack shit apart from that. It would accomplish exactly what XP N did- sell zero units, but satisfy regulators that indeed, the public isn't being denied choices it really wants.

  5. Re:The clock stops when the pad is first touched on Timing Technology Behind Olympic Record Results · · Score: 1

    Did you ever wonder why they all touch the pad with both hands?

    They touch the pad with both hands in butterfly and breaststroke because that's the prescribed form for the stroke. If they didn't, they would be disqualified in those events. I've competed as a swimmer using these systems for over 2 decades, and I've served as a stroke judge and timer at countless meets using these systems; competitors, coaches, and judges are notified about the rules and how they're enforced.
    As far as I can tell, (this is just my white-box observation) the touchpad doesn't seem to know what stroke you're swimming, and so doesn't know whether to expect a one hand-touch vs. a two hand-touch, or any of the hand-then-foot or just-feet touches it measures for splits and turns, or any other touches (elbows, heads, etc) that touch the wall at the finish. The same pad is used to time backstroke and freestyle events, which don't presribe a two-hand touch, and yet the touchpad captures those results without the need to differentiate one kind of input from another. Based on my knowledge of how the rules are enforced, the timing of the second hand-touch is irrelevant. As an engineer, solving the problem of actually measuring the timing of the second hand-touch would not be trivial (specifically, how to determine which touch is the second hand-touch?). Given the irrelevance of such a measure, the lack of input into the system to tell it what sort of input to expect or how to differentiate differing kinds of touches, the complexity of the problem, and the fact that judges, coaches, and competitors are explicitly told that the touch pad captures just that first touch, I'd be very surprised indeed to hear otherwise.

    I've played with and tested these systems over the years (you test the system every time you set it up). I've officiated at meets using these systems (both as a stroke judge and a timing official). I have never seen any procedure by which to tell the system what sort of touch to measure. The testing sequence by which to validate the timer is to start the system, then touch the pad once, firmly, with your fingertip. Hey, I could be wrong in my conclusion here, but I'd need to see some pretty compelling evidence to make me think otherwise. Got any?

    If 1/100 second is the accepted resolution for swimming and any smaller interval is considered a tie, there doesn't serve much purpose in taking more photos

    Indeed. There was at least one shared medal in these olympics as a result.
    Note that when a tie needs to be broken (for example, to determine who advances on to semis or finals) it is done in a swim-off heat (this happened at least once during these games) rather than by going to the next decimal point.

  7. The clock stops when the pad is first touched on Timing Technology Behind Olympic Record Results · · Score: 4, Informative

    according to fucking rules, you need to press the sensor(s) with both hands, eh? That's why people complained about the lack of frame(s) which show that moment.

    Actually, his post is correct. The clock stops when the sensor is touched by that first fingertip- and Phelps clearly made it to the wall first by that measure. The camera and the electronic sensors agree on this.
    The decision as to whether or not he did it according to the rules is a separate one. The rules for butterfly require that your shoulders be level, that your arms come around symmetrically and above the water, and that you touch the wall with both hands at the same time- but there are allowances for slight imprecisions in this regard, and Phelps was well within those tolerances. What the judges would look for is whether Phelps galloped his stroke (i.e., brought his arms around significantly assymetrically), if he would have stroked with one hand while lunging with the other, if he'd lunged over on one side, or if he'd kicked assymetrically in such a way that would get him some advantage. He did none of these things- at the finish, his body is straight, his shoulders and hips are level and square, his feet together.

    What this came down to was stroke timing. Once you commit to the glide phase of a butterfly stroke, you can't break that straight-armed glide position unless you stroke through past your shoulders and recover both hands forward above the water. Approaching the wall, the two swimmers were out of phase with each other, with Phelps gaining ground- in such cases, it's always a matter of some strategery to time your stroke most advantageously, since in that drive phase of the stroke your hands can't reach forward to the wall and you're decelerating in your glide phase. Cavic stretched his last glide/lunge really well- given where he was in his stroke cycle, it wouldn't have made much sense to take another stroke. Phelps, on the other hand, was more than half-a-stroke away from the wall at the point where he needed to decide whether to take another one, so essentially he didn't do any gliding in- he touched the wall on the down-beat drive phase of his stroke, just barely in time to out-touch Cavic.

    From what I can see, (based on having swum competitively for 20 years) I agree with the result- Phelps clearly won, if only by a very teeny margin.

  8. Re:The photo/camera finish was totally inconclusiv on Timing Technology Behind Olympic Record Results · · Score: 4, Interesting

    That rule is intended to keep people actually swimming butterfly, and it's OK if your hands touch slightly apart time-wise. What's not OK is if you break form (by stroking with one arm while lunging with the other hand) to attempt to out-reach someone, or if you don't bring both arms forward on that next stroke.
    Phelps' shoulders remained square, he brought both hands around consistent with the rules, and the judges made the right call here.

    Also note- the touch pad has no way of measuring when a swimmer touches with both hands, it only measures when contact is made. It is this contact that determines one's time, not the placement of the second hand. Once the time is turned in, the decision of whether it was legally accomplished (or a DQ) is a separate one.

    Yes, they measure military skills- but they're still made-up games. For example, to win the javelin, shot put, or discuss event, you throw for distance (which is only a small part of their military applications- for example, hitting a target isn't part of the game, but it is definitely the point of the skill). Wrestling is a game with rules to keep combatants safe, and is not something you'd see in actual real-life military application. Same with boxing, fencing, etc- they allow one to develop and practice skills transferrable to other (in this case, military) applications, but there's no inherent value or point to the actual game itself.

    People need to stop gawking at how many medals he's winning. They represent winning events that vary little in terms of training and skill.

    Spoken like someone with neither the training, experience, or skill. The truth is that swimming is full of specialists now- and the training and skills from event to event are significantly different. There's a reason we haven't seen someone cross over so many events like this since Mark Spitz (36 years ago)- it's because that's how often someone comes along who can really compete across disciplines and beat the specialists at their own games.

    I started swimming at age 6 and made it to the national level in college. I was a sprint freestyle specialist, and the training I did differed quite a bit from, say, what the backstrokers or IMers or the Flyers or the distance swimmers did.
    For example, we would train for higher peak heart rate capacity than the longer-distance folk; we would hit heart rates of > 260bpm while most of the distance folks didn't have the ability to get there- they'd hit v02 max (muscle failure) before they could tax their hearts that much. This called for a lot more power training than the distance folks. Meanwhile, their aerobic-oriented training rendered them much stronger at distance than anybody in the sprinters' lanes.

    Yes, it's all swimming, but to excel at different disciplines calls for significantly different training and approaches, which typically cost a swimmer the ability to train optimally for others. For someone to perform like Phelps has in these games is special indeed.

    mmmmm... a heating oil subsidy would merely ensure that no alternatives become available. The purpose of a subsidy is to insulate people from the price pain of consuming, yes? If you watch the way people behave (as distinct from how they talk), you'll note that we respond to price, not to moralizing. Without the pain telling us to change, no change will occur.

    A subsidy would signal to consumers that conservation is unimportant. It would also signal to producers of alternative energy and competing technologies that this isn't a market worth investing in, since the underlying utility (energy) is made artificially cheap and therefore hard to compete with.

    If we'd been half-smart, we'd have done for ourselves 5 years ago what the market's done for us today: Drive up the price. A $1/gal tax on gas, whose revenue offset an equivalent cut in payroll taxes would have allowed us to pay for our investments in efficiency, while incentivizing the same- instead, we're just sending those dollars direct to Venezuela and Saudi Arabia.
