  1. Find the power plug on A Mobile Robot For Modeling The World In 3D · · Score: 4, Interesting

    Great article (hope it doesn't get /.'d). While they seem to be working on large-scale room features (wall, door, floor, ceiling), I can see the next step being an autonomous robot that can find and identify such basics as a light switch and a power (mains) outlet.

    I remember years and years ago, a robot had been developed that could optically recognize a power outlet and plug itself in... but I don't think it did much else. This would have been early 80s, probably, so we're talking Z-80 vs. Pentium.

    Future recognition goals:

    * Refrigerator door (fetch beer, please)
    * Small child (danger! sticky fingers! run away!)
    * Other robots for romantic interludes:

    Did you hear that IRS, I donated the $36 million dollars! It was me!

    That brings up a good point... somebody is getting a whopping tax deduction for their gift. While that's perfectly appropripate, we have three problems.

    One, the citizens of Georgia are going to be contributing another few million bucks for the project. Don't they deserve to know where their matching funds are coming from?

    Two, I and my fellow Americans will be contributing indirectly, via the charitable deduction the person or company is going to receive. Don't I deserve to know whose tax break I'm going to be offsetting?

    Three, while there are plenty of true philanthropists, that kind of cash usually comes from someone with a dog in the fight. Bill Gates "generously donates" Windows PCs to schools like a drug dealer "donating" crack behind the bleachers. As an investor, don't I deserve to know if company X just put $36 million into a technology that will benefit it? Don't I deserve to know that company Y *isn't* investing in the future?

  3. We don't know squat. on Yet Another Big Solar Flare · · Score: 5, Insightful

    From the article:
    Space weather forecasters say this spate of strong solar flares is not consistent with normal solar behavior. The sun, which follows an 11-year activity cycle, has been quieting down since the last peak in 2000.

    Although we humans have been looking at the sun since before we climbed out of the trees (and our moms have been telling us not to even longer), it's almost silly to say that any observation of our local star is "not consistent with normal solar behavior." Just how many of those 11-year cycles have been recorded?

    If the ancient Chinese were using pinhole solar viewers to count sunspots for the past 5000 years, that would be one thing. But as has been posted in every Slashdot story on the subject, we have maybe 200 years of scientific data (of varying quality) out of the sun's five billion year history. Even W's pollsters would tell you that sample size is too small.

    frankly, I'm wondering how they'd stop a hydrogen buildup similar to a sonic boom from forming and causing some real damage to the systems they're travelling to or past

    What episode of TNG was it where it was discovered that high warp speeds *did* cause permanent damage to interstellar "ecosystems"? As I recall, it was an interesting allegory of "freedom fighter" vs. "terrorist", with the planet's scientists (all two of them, as usual) split on how to convince Federation starships to slow the hell down.

    In the end, one of the scientists demonstrated the problem the hard way, blowing himself up in the process, and the Federation imposed a speed limit (warp 5, wasn't it?) unless there were a lights-and-sirens emergency. I always wondered how the Federation would enforce such a limit, especially on folks like the Klingons and Borg who never showed much use for the Federation's benign dictatorship.

    Wow, tell me what kind of cereal box contains a model of the Enterprise and i'm all over it!

    Well, I may have exaggerated, or taken poetic license. I mentioned later on about the snow globe option... this was from personal experience.

    My mother bought my wife and I a huge snow globe of the Enterprise (classic '60s version) one Christmas. We put it up in the closet until the kids got old enough to be interested. The next step is sadly inevitable: a busted snow globe and a cheap plastic model of the Enterprise that doesn't look nearly as cool as it did through the curved glass (now in a puddle of water on the floor).

    I suspect that a similar situation may have offered up the candidate for the wind tunnel test. Note the big horizontal seam in the model -- I think my "model" may have been built the same way.

  7. Obligatory retort: give them a break! on Star Trek Enterprise Tested to Mach 5 · · Score: 5, Insightful

    Allow me to begin the second phase of stock Slashdot comments. Phase I has already taken place: "what a waste of taxpayer/foundation/whatever dollars!" Phase II begins now:

    Lighten up! It is clear from a very quick look at the rest of the site that the "Enterprise" simulation is just a fun application of some very serious science. It's clear that no special apparatuses (apparati?) were constructed to provide a real simulation of the Enterprise -- in fact, it's pretty obvious that the model used came out of a cereal box, or something.

    Day in and day out, it looks like these guys are engaged in cutting-edge wind tunnel science, testing object against forces so strong, they can only be simulated for tiny fractions of a second. This means that someone spends hours setting up everything within rigorous parameters, then pushes a button. "Bam!", and it's over. If the object under test was mispositioned by a fraction of a millimeter, the team gets to do it all over again.

    Once -- just once -- they'd like to have a chance to do something fun with the equipment. Someone has an old Enterprise model (actually, it may be from a snow globe). After a long day (probably unpaid) of testing the frontiers of science and boredom, they load up the (already warmed up) machine and have a little fun.

    Thanks to the 'net, we get to share their fun. And in another few decades, we may get to enjoy the results of their hard work when we book that vacation on Luna.

  8. The one time patents would be a Good Thing... on Better Living Through Chiral Chemistry · · Score: 2, Insightful

    For once, a patent would appear to be supporting innovation. An individual with an idea sees the potential, files a patent, and goes on a quest to commercialize the product. There could be no better case study of how patent law is supposed to encourage innovation.

    But alas, it's not to be. From the article:
    The patent on tagatose as an additive expires in 2006, the two patents on production methods a few years later. [Inventor Gilbert] Levin hopes to see his sugar substitute flood the market before then.

    Meanwhile, the current silliness at the patent office will help ensure that Levin will join the legions of brilliant inventors with "died nearly destitute" included somewhere in their epitaphs. Instead of an individual getting his due from an actual original thought, big corporations are set to reap millions from ridiculous "business method" patents. Again, from the article:
    Kellogg's obtained a patent in 2002 to use tagatose in "improved sucrose-free, noncarcinogenic, reduced-calorie, insulin-independent" sweet cereals. Wrigley and Kraft have patents of their own.

    A: Note: This function only works on part number 2800308 - Gateway 42-Inch Viewable Area Plasma TV R1.
    1. On the remote control, press the left arrow button for more than 5 seconds, and then release.

    2. Press the right arrow button for more than 5 seconds, and then release.

    3. Press the Favorite Channel (FAV. CH.) button, and then release.

    4. A bright white eraser screen appears. This eraser screen refreshes the Plasma screen and reduces the visual effect of burn-in.

      Note: The eraser screen needs to remain active for a period of time. The more severe the burn-in, the longer the eraser screen needs to be left active. A light burn-in can be taken care of in about 12 hours. A heavy burn-in may require up to 50 hours. The test can be tailored by running the test for a given number of hours, and then making a judgment. If the result does not seem good enough, run the test again until satisfactory results are attained.

    5. To shut down the eraser screen, press the Favorite Channel button, and then release it. If necessary, repeat this step until the white screen disappears.
    Great! Not only do the instructions sound like DDR cheats, but Gateway is telling me to fight burn-in by burning in the whole screen for 50 hours! A few "masterpieces" later, and you've got a $10,000 night light.

Advertising on a bill treads just a bit closer to the border between "fun" and "defacement". As an example of what happens when you get too close to the border, Hank (the WG? webmaster) was "urged" by the Feds to stop selling "Where's George?" rubber stamps on wheresgeorge.com, to avoid the appearance that the stamp was intended to push stamp sales.

    The way this is worded, it sounds like they're implying "the project will cost as much as you'll let us spend." I'm really leaning toward the view (often expressed by Slashdotters) that the government needs to move from a leading role to a supporting role in space technology. And note that in the term "government", I include the big government contractors like Boeing & co, whose corporate inertia is no better than government bureaucracy.

    Give the funding to outfits like Armadillo and the rest of the X-Prize competitors. Why not a government-sponsored X-Prize competition, with the winner getting a juicy government contract?

    "Sweet spot" for advertisers... "Crap that clutters my search" to me.

I decided against GreenCine in part because subscribers report low supplies despite an excellent selection. You get the idea.
