  1. Under 25? on Tesla Releases First Official Photos of Model S Sedan · · Score: 1

    Heh, I think by that logic I've been under 25 for more than 35 years now...

  2. Re:Imagine buying one of those... on Tesla Releases First Official Photos of Model S Sedan · · Score: 1

    Ah just realized that the "interior images" is not model S images... disregard the above... Their web site could be a bit better organized.

  3. Re:Imagine buying one of those... on Tesla Releases First Official Photos of Model S Sedan · · Score: 1

    The body work is different, but the interior is clearly still related to the Lotus Elise. The cowling over the speedometer, and the air vents in the dash are leather coated versions of what I have in my car. It kinda looks like they still don't have a glove box or cup holder... just like the Elise.

  4. Re:Hot Coffee was bad enough on The ESRB Doesn't Take Games Seriously? · · Score: 1

    Did you notice that the author said "Here in Germany"? Don't think he's American....

  5. Or we could read the article and discuss that... on Cookbook For Third-Party Apps On iPhone · · Score: 1

    How about thinking about the article... Thoughts I had include a very obvious bit... maybe they should remind people to change their password (or is that not possible?)

    If the password can't be changed, you are VERY vulnerable... sniff a popular wireless network, look for web traffic that has the Iphone user agent in it, ssh to that ip and try the password given in the article.

    Also, does this jailbreak technique void your warratee?

    Will your changes all get blown away on the next apple iphone update? (or will they get in the way of said update?)

  6. Skilled opponents on 10 Years After Big Blue Beat Garry Kasparov · · Score: 1

    It is true that a skilled player can provide better examples, and better review after the game. Having such a resource is wonderful, but much can be learned simply by playing. As a specific example I offer myself. I played go for over a year against a computer program before ever facing a live opponent, and it wasn't even a good computer program. I am now about 3 kyu now and I would estimate the rank of the program I played against as approximately 22k. When I logged on to the No Name Go Server for the first time, a 9k estimated my rank at 17k based on a 9 stone game. I quickly attained a rank of about 15kyu, though I *think* my first confirmed rank was indeed 17kyu. In that time I read no materials on Go other than the rules that came with the soft ware (which was a bundle called Mind Games Entertainement Pack distributed by EDO software). So yes you can learn without a stronger opponent to teach. The only thing I had as a head start was some experience as a (poor) chess player from high school, so the general habit of thinking through a series of moves was something I had already learned. Among the concepts I at partly understood from mere play included a number of end game tesuji for simple captures, the trade-off of speed vs connectedness among the nobi, the diagonal, the one space jump, the knights move jump, the two space jump, the large knights move jump, and the diagonal jump. In this day and age, there are many helpful websites, and go books are easy to find on go related vendor sites, as well as Amazon/Barnes&Noble etc so you don't have to discover everything yourself like I did in 1995-96, so if you add some reading to regular play against almost any opponent, you will make progress, particularly if you increase the handicap when one player starts winning regularly.

  7. Re:The goggles, they do nothing! on 3D Animations In Mid-Air Using Plasma Balls · · Score: 1

    Yeah really now... plasma, where else do we find that... Arc welding? Note the goggles that everyone wears. I suppose there are companies who would want to burn their logo onto your retina though...

  8. Go is different, give it some practice. on 10 Years After Big Blue Beat Garry Kasparov · · Score: 2, Interesting

    Yes. The go proverb for this is "loose your first 100 games as quickly as possible". The hidden truth in that statement is that Go is a somewhat different game than most others. The pieces are stationary, and can't run away from danger. It takes some repetition to quickly perceive the way in which the continual addition of stationary stones can create the same effect with respect to a group of stones. In go you don't "run away", you "grow away" :).

  9. Re:the supercomputers advantage... on 10 Years After Big Blue Beat Garry Kasparov · · Score: 1

    Yes, and not coincidentally, 9x9 go is quite similar in complexity to Chess. The full game however is still a long way off.

  10. Re:the supercomputers advantage... on 10 Years After Big Blue Beat Garry Kasparov · · Score: 1

    Sorry, to be more precise, I should have referred to the branching factor... For example the first move of a chess game, has 20 possible moves, the first move of a Go game has 361 possible moves. so 1 pair of moves at the start of a chess game is 20x20 = 400 possible positions, whereas the first pair of moves is 361*360 = 129960 possibilities. Starting on move 7 stones can be removed from the board in some branches re-opening the used points and so at that point the possible positions begin to exceed 361!/(361-n)! where n is the number of the move about to be played. Even in the end game in chess, usually has less than 100 possible moves. The average Go game is around 250-300 moves except when one side resigns early (The Wikipedia article I cite below is wrong about the average game length, it is indeed quite hard to achieve a finished game by 200 moves without resignation), chess around 80. I've played over 120 though back when I used to play chess, my longest go game is 365 moves (yes, more than there are spaces on the board, it does happen, and games over 400 moves have been recorded) As for search space, The search space for Go is 10^360, so from the perspective of Go, the search space of chess is much, much, much smaller than an atom is to a human being. But more than all of that, Go can't really be reduced to local battles. A single move can have profound effects across the entire board. The most famous example of course is Shusaku's Ear-Reddening move.

  12. Re:the supercomputers advantage... on 10 Years After Big Blue Beat Garry Kasparov · · Score: 3, Informative

    Computers playing chess is mostly an expression of the advances in computing power, and only slightly of our ability to create AI. Chess has too small a search space, and brute force is quasi-feasible. Larger games such as Go, (a.k.a. Baduk, Wei qi) are far more interesting, since the board is too big and the subtle effects of a single play radiate across the entire board. Computers still can't even come close to beating a talented child let alone a ranked professional. (Go is also a really fun game to play... a little web searching will tell you more about it.)

  13. RFID pointless on RFID Drivers' Licenses Debated · · Score: 1

    There is no need to make it RFID. A smartCard offers substantially more control over the presentation of the information. Either way you need a smartcard reader or an RFID reader so specialized hardware is required in both cases, but smart cards can't be read accidentally. Or without your consent (unless you loose them, just like regular licenses)

  14. Re:Sweet on Education Via Video Games · · Score: 1

    Try reading the article: "The program is being distributed to employees in Michigan's extension offices who teach food aid recipients how to be efficient shoppers. So far, they seem to like it better than the usual brochures and charts, said Gayle Coleman, the extension service's interim state program leader for family consumer science." It sounds like the needy arn't taking it home to play it, but playing it in house.

  15. horse puckies are made of grain :) on Smarter Children Through Food Supplements · · Score: 1
    Another vote for horsepucky :). "Grain" is the seed of any one of a variety of cultivated (usually grassy) plants. It only becomes efficient to harvest and eat it when it is available in fairly large monoculture... Farming isn't particularly old in terms of evolution. I would be willing to accept that starchy tubers, roots, and fruits were an important part of our diet, but until the advent of agriculture grain was probably an occasional windfall.

    Harvesting the seeds specifically is quite important. We certainly are not well adapted for grazing. We have a fairly standard issue digestive system, and our teeth only get replaced once (horses, and cows have specialized digestive tracks, rodents and lagomorphs (rabits) have teeth that grow continuously). Even more importantly if we apply our teeth to gathering grass we can't see any approaching predators, (or the aproach of other groups of humans). We would be well suited for detecting ravenous earthworms and snails however. Since grassy plants are mostly indigestible cellulose we would also have to spend most of our time pulling it out with our hands just to get enough nutrients, and it won't be as easy as weeding a garden either. Havesting and processing the seeds is very important... oh yeah and it's highly seasonal too :) we would have to eat something else for the remaining 10 months of the year anyway. (The african plains have dry and wet seasons folks, I know they don't have summer/winter)

    It's also very well established that many (I suspect most, but I don't have any numbers to cite here) pre-agricultural peoples hunted. Also note, people (like wolves) are very well built for endurance running. In fact we are even built for endurance in a high temprature environment (we sweat profusely and have a large surface to body mass ratio, unless of course we eat too many cheetos). We are remarkably poor sprinters (20-25mph for 100 yards or less is very slow for an animal of our size). If you can't sprint you won't get away from most predators, but endurance running can be used quite effectivly to run down large animals, especially for herding them into traps and ambushes.

    Also I think for analysis of our evolved state with respect to diet, the relevance of our past behaviors is decreasingly relevant the further into the past you go. If you take it back far enough primates all evolved from a sort of tree shrew, and it probably ate insects. The most relevant thing is the condtions of early agriculture, and pre agricultural hunter-gatherers. IMHO at least.

  16. Re:Remember on Bush's Space Panel Seeks Public Input · · Score: 2, Insightful

    Ya know I used to think things like that about people who did non-scientific work. Then I found myself paying bills by working making signs... And despite a Masters Degreee in a scientific field, it turned out that the barely finnished highschool 8 years ago sign man who was the lead guy in the shop could build it better, faster, with fewer mistakes and was in every way more profitable for the company than me. He repeatedly had to show me how or rescue me from myself. I program computers now, but the lesson was very valuable. The motor skills, and tricks of the trade and all the little details involved in building something are very real knowledge. Chances are if you tried to work an assembly line you would screw things up regularly when you started. And the people you are looking down your nose at would all be making fun of you.
