  1. Re:So... on Amazon Kindle 2 Leaked, Sony Reader To Get Touch Screen · · Score: 1

    PDF support is not the same as being able to view an entire page of text without having to scroll madly or have the text illegible. I don't know if 600x800 is good enough for reading say, scientific papers.

  2. So... on Amazon Kindle 2 Leaked, Sony Reader To Get Touch Screen · · Score: 5, Interesting

    Can I read run-of-the-mill letter-size PDFs on it yet?

  3. Looks like ass on Stargate Worlds Beta Begins Oct. 15th · · Score: 3, Interesting

    I realize this is beta, but this is definitely catering to a crowd that I can't identify with. I didn't expect this to be canon, but are those Ori footsoldiers with p90s? I wish whomever plays this hours of enjoyment, but it's a bit too Elder Scrolls for this die-hard SG fan. In the words of PA, it's not "for me"

  4. Re:The human aspect on 16th World Computer Chess Championship In Progress · · Score: 1

    The game-tree complexity of chess is estimated to be around 10^123. It is estimated that there are around 10^80 atoms in the visible universe. That is what I meant by cosmologically large. You would need many universes worth of storage in order to store that database. But I will agree with you that computing is full of surprises. I have a good amount of faith that factoring RSA-2048 will be a second-year quantum-comp-sci assignment in 20 years =)

  5. Re:The human aspect on 16th World Computer Chess Championship In Progress · · Score: 1

    The day will come where computers can just have a database of every single possble chess move in any game.

    I understand your point, but I don't see that happening. Even with quantum computers, that would be quite the feat. The chess search space is cosmologically large

  6. Any standardized championships? on 16th World Computer Chess Championship In Progress · · Score: 1

    Are there any challenges out there that limit what sort of computing power you may have? Sort of like the Loebner prize, but for chess. I think algorithms would get much more interesting if every contestant had to limit themselves to some standard configuration like a dual core 5000+ with 2 gigs of ram and 64 gigs of SSD. Granted, that hardware is going to be long in the tooth in 2015, but the algorithm that wins in 2015 will probably give mr 40 core supecomputer a run for its money.

  7. Technology on Now Google's CAPTCHA Is Broken · · Score: 1

    I hope these black hat methods of cracking fall into the mainstream. We can probably learn a lot in the ways of computer vision and AI from this arms race. Or maybe this isn't "state of the art" but the people who design captchas in the first place don't have good cross-fertilization with the AI crowd.

  8. If you're wondering... on Advanced Excel for Scientific Data Analysis · · Score: 1

    ..."When does exponential decay function stop?" scientific data analysis is definitely not for you. How about "How is babby formed?"

  9. Re:Well on Strong Methane Emissions On the Siberian Shelf · · Score: 1

    Canned foods? Isn't that what got us into this whole methane problem in the first place?

  10. £5 billion on Japanese Begin Working On Space Elevator · · Score: 1

    What's that in Volkswagen Beetles?

  11. Deletionism? on Debating "Deletionism" At Wikipedia · · Score: 5, Funny

    The politically correct term is "Intelligent Unpublishing".

    Anon delivered.

  13. Re:I liked it. on Microsoft Uses "I'm a PC" Character In New Ads · · Score: 1

    How many "every day people" dive with sharks or have been to outer space? I get the point, and everyone has something special about them, but I think they're trying to hype "cool without trying" instead.

  14. Availability on How Nvidia Wants To Bring 3D Glasses Back · · Score: 1

    A quick search revealed that these glasses are already available for sale

  15. Smudge on the lens... on Hubble Finds Unidentified Object In Space · · Score: 1

    ...or dirt on the sensor.

    Steel, not iron!

    "and the study subjects...men at least 5 years into a heterosexual relationship."

  18. Re:A mile? on ISS Dodges Space Junk For First Time In Five Years · · Score: 5, Informative

    At the risk of being redundant, it's roughly a 1 in 72 chance that their calculations of a "miss" are off. Calculations of this sort involve a margin of error, from not precisely knowing locations of these objects to not being able to do forecasting accurately enough. Debris A gets hit by debris B (which somehow evaded your radar), sending off two new chunks of metal which weren't even IN your original calculations. I'm actually impressed that they can put solid numbers on these things, but I guess that's what supercomputers are for.

    Yay for safety margins.

  19. Re:Cool but... on Rocket Racing League Flights With Armadillo Engine · · Score: 1

  20. Gramophone record on Digital Storage To Survive a 25-Year Dirt Nap? · · Score: 1

    If I were to shoot for 250 years instead of 25, I would probably store whatever digital data as a tone modulated signal written onto a durable gramophone record (metallic, perhaps). It is technologically primitive enough that you'll be able to get it back into digital format with basic tools of the day (assuming no catastrophic collapse of civilization as we know it)

  22. Was the inventor? on James Powderly of Graffiti Research Labs Detained In China · · Score: 1

    That's sort of fatalist, isn't it? I'm sure he'll be released in good time.

  23. Nope... on Mimicking Photosynthesis To Split Water · · Score: 1

    Unless you were touching the Sun. I believe the point of maximum efficiency is reached once the thing that you are heating radiates as much heat as is incident upon it (per unit area). Because of the distance between us and the Sun, the intensity of light reaching is is lower. Say you build a setup of lenses and mirrors on Earth, and that this setup focuses the sun's rays onto some object, and that this beam has intensity X, heating the object to the Sun's temperature. X is therefore also the intensity that the object is radiating, and for sake of argument, say it is given by s T^4 (Stefan-Boltzmann). Moving this set-up closer to the sun increases the incident intensity by a factor of (R_f/R_i)^2. Since the set-up of lenses hasn't changed, the object must now radiate more to stay in thermal equilibrium, and so it's temperature must increase. By assumption, it's temperature was as high as thermodynamically possible, and we arrive at a contradiction.

  24. Re:Cambrian Explosion of alternative energy techni on Mimicking Photosynthesis To Split Water · · Score: 2, Interesting

    I think focusing sunlight to thermolyse water in that way might violate thermodynamics. I think you'd need to get closer to the sun. Maybe someone can give us hard numbers...

  25. Re:Hmmm on 'Slow' Light To Speed Up the Net · · Score: 3, Insightful

    I think the point is that the light pulses are slowed down enough that they can be manipulated by optical switches. By eliminating two conversion processes, the time between when the pulse arrives at the switch/router/booster and when it leaves is still shorter than with the electronic system. As far as I understand, it isn't related to reducing congestion by "slowing down" packets.
