  1. A new chargers infrastructure ? on Growing Power Gap Could Force Smartphone Tradeoffs · · Score: 2, Interesting

    It seems it will be a while before there will be significant progress in batteries. As a stop-gap measure is it realistic to deploy network of chargers? Chargers at cafe, shops, gov offices, ATM and phone booths. Preferably inductive chargers to evade connectors hell. Cellular network operators can brand them, to give them incentive. Payment can go into phone bill.

  2. No on Soviets Built a Doomsday Machine; It's Still Alive · · Score: 1

    Could Iran destroy America by dropping a nuclear weapon on Russia and letting Perimeter do the dirty work for them?

    If this Perimeter exists it can launch attack only if Command&Control structure is destroyed or isolated. No earthquake or rogue state can do it, even if the Kremlin evaporated - there are several reserve HQ around the country. Only deliberate decapitation strike can damage C&C enough to trigger automatic response. There is only one state capable of such strike for now.

  3. Re:Speaking as a chemist on Most Detailed Photos of an Atom Yet · · Score: 2, Informative

    Up until this very moment I have been under the misguided notion that the nucleus of an atom was orbited by electrons within groups called "shells", and these worked very similarly to satellites around a planet.

    Think of a satellite randomly teleporting around the planet, leaving ghostly afterglow behind. The "glow" would have the shape of those shells. Or the "brightness" of the shell is the probability of existence of "satellite" in the point of space. What gives orbitals their shape is the Schrodinger equation.

  4. Poor terminology on Variety, Social Aspects More Important To Game Success Than Graphics, Plot · · Score: 4, Insightful

    Authors of TFA defined "Variety" as "non-linearity, choice, dynamic combat, varied AI, emergent tactic". That is what's usually called "Gameplay". What they are calling "Gameplay" - "Engaging, fair, balanced, innovative..." is mostly a pile of marketspeak.

  5. It's not a rate of technological progress slowed on Has the Rate of Technical Progress Slowed? · · Score: 1

    It's a rate of advance in fundamental science which is slowed. In fundamental physics all low hanging fruits are picked, now quantum gravity become a major stumbling block. Modern mathematics become so complex that it seems even outstanding human brains have trouble to cope with it, behavior some of the finest mathematicians is becoming bizarre (Grothendieck, Perelman) To lesser degree the rest of the science also becoming increasingly more complex.
    No breakthroughs in fundamental science - no fundamentally new technologies like atomic energy. However intelligence amplification can break this stalemate.

  6. Re:Loosen up, folks. on Pigeon Protocol Finds a Practical Purpose · · Score: 1

    Some RKKA (Soviet army) divisions still had pigeon stations in OOB just before the start of WWII. There is no evidence they were actually used in WWII, but they could have been useful. With contemporary radio unreliable, and cables and land communications disrupted by German armored spearheads in the beginning of the war, Red Army command had often to relay on one-way dispatches dropped from airplanes. Pigeon connection could have provided two-way communications with cut-off groups.

  7. Re:Think of the possibilities! on Augmenting Reality With Your Mobile Phone · · Score: 1

    This would be pretty cool ... find 10 distinct points on the video feed, and keep the (whats the noun here? "targeted location"?) tube station, pizza shop or whatever in direct relation to the video, rather than having the lag of constantly polling the GPS + magnetic compass, leaving the targeted location lagging badly behind the video

    Actually what you are describing is the definition of augmented reality according to Azuma - "registration in 3d"
    This GPS and compass thingie is kind of self-proclaimed AR, and sadly this understanding of AR as anything overlaid on a video and loosely attached to location substitute now Azuma definition. Azuma definition was even purged from wikipedia.

  8. Android have problem of it's own on Augmenting Reality With Your Mobile Phone · · Score: 2, Informative

    You can't have non-trivial mobile video tracking in java - I mean anything more than unstable tracking of single rectangle. Android native code kit - NDK have some promise, but camera class access still not officially supported in NDK. As I understand you can still use it, unofficially, but you can have unofficial access to camera API in iPhone as well.

  9. preinstalled TLS/SSL certificates on Nokia Launches Pay-By-Phone Service · · Score: 2, Informative

    security practices in GSM networks were below standards

    If proper certificates preinstalled on the phone and bank server by phone manufacturer, public key crypto shouldn't be vulnerable to man in the middle, and insecurity of GSM wouldn't matter. Nokia is exactly in position to do it.

  10. Written by who? on Poor Design Choices In the Star Wars Universe · · Score: 1

    Scalzi himself have problems with world design as well. In his Old Man's War universe in book three it's suddenly revealed that good guys of first two books are actually bad guy. Colonies military leadership, smart, efficient, canning and somehow cynical but dedicated to protection of humanity in the first books, suddenly happens to be dumb power-grabbing war-mongering egoistic parasites in the next two books.

  12. Taiga on Northern Sea Route Through Arctic Becomes a Reality · · Score: 1

    If I lived in a country like Russia (or Canada, Norway, Finland, etc, for that matter), I'd be an enthusiastic supporter of anything that might even possibly tip the balance of the climate towards Global Warming for exactly these sorts of reasons. I mean, if you owned the largest frozen mass of land anywhere, why even care about such a cause?

    Global Warming is turning huge expanse of Taiga forests into swamps. SO not everything is rosy for Russia

  13. This is not augmented reality yet on Wearable Computer With Lightweight HUD · · Score: 1

    Augmented reality need camera, so that camera image can be registered in 3d and overlay drawn over it could be seen as organic part of the scene. As it is this is just a wearable display.

  15. You will laugh but that's exactly what happening on Iran Tries To Pacify Protesters With Lord of The Rings Marathon · · Score: 1

    Seriously, how many 'brown skinned' people do you think are going to look at orcs on the screen and say, "oh, that is me."

    Russian LOTR readers quite often identify with orcs or easterlings. People under the red sign, from the east, to whom "free people of the west" want to bring just rule, proper king or maybe just exterminate. There is a lot of fan-fiction written from point of view of orcs, or simpatizing to orcs, most notable of wich are Perumov's "Ring of Darkness" and Eskov's "The Last Ringbearer"

  16. And how is this a news ? on String Theory Predicts Behavior of Superfluids · · Score: 1

    Maldacena duality is discussed for more then ten years already, "dual black holes" on the RHIC is of 2005 and application to the superconductors is of 2007. So why now ? Are there any new development? Or it's just slashdot catching up on the tow years old news?

  18. Data out of thin air ? on The Electronic Police State · · Score: 1

    I've checked raw data xml and was quite surprised. Take for example Israel, which I'm quite familiar with. While Israel could be very close to police state for obvious reasons it does not look like electronic police state to me.
    Now raw data for Isreal form TFA (scale 1-5):
    Daily documents - 3. Not quite reasonable, I would put 4 at least.
    Border Issues - 3. Wrong. While border search is intrusive, electronic data are not inspected usually.
    Financial tracking - 3.Plausible.
    Gag order - 3.Questionable. Courts issue a lot of gag orders, but usually not related to searches.
    Anti-crypto laws - 2. Wrong. What anti-crypto laws in Israel ?
    Constitutional protection - 3. Absurd. There is no constitution in Israel.
    Data storage ability - 3, Data Search Ability - 2, ISP Data Retention - 2, Telephone Data Retention - 3 Cell Phone Records 3 - How did they got those data ?. Sure there were admission of surveillance by police, but how it translated to numbers ? Why Data storage ability is 3 and Data Search Ability is 2? It seems they just estimated Israel tech level and added some random variation.
    Medical record - 1. Dubious. There is no problem for law enforcement to get medical data. There is only four medical insurance companies in Israel, and data are centralized and easily obtainable. Should be 3 or 4.
    The rest seems plausible.
    Now, out of 17 points 4 or 5 are wrong, 1 is completely absurd and 5 is suspicious. Looks like however compiled this table just put some number into it out of the thin air.

    Wired: The Formula That Killed Wall Street
    David X. Li formula used "Gaussian copula function" for risk estimation. It greatly oversimplified risk estimation and ignored any nonlinear, topological and whatever nontrivial dependencies, taking into account only single correlation parameter. Formula was applied recursively and the end result was completely divorced from reality.

  22. Re:C API yet? on Android 1.5 SDK Is Released · · Score: 1

    Yep, I'm one of those devs. I'd love to try android, but even with native code I'd to use a lot of tricks to make image registration code run on the mobile CPU with acceptable frame rate. There is no hope it will run on Java (some benchmarks show 10-100 times slowdown, but even 30% slowdown would kill it). Of cause solution could be if image processing/registration would be implemented as a part of native android distribution itself, as was suggested in some discussions. Even better if it would use DSP/IP/FPGA. But those are pipe dreams of cause.

  23. String theory usefulness on Strings Link the Ultra-Cold With the Super-Hot · · Score: 1

    Has string theory truly helped us understand anything better? If it has improved our understanding, what predictions of physical phenomena have come of this increased understanding of the physical universe?

    I'm not a physicist, so my understanding is very limited, but the answer to you question is "probably yes".
    The thing is the phenomenon string theory help understand and predict is not related to quantum gravity, for which string theory is developed. This thing called Maldacena duality and state that certain quark-gluon interaction have the same mathematical description as stringy black hole. Surprising thing is, that it seems such quark-gluon object - "dual black hole" was observed at RHIC collider. Why "seems" in that statement ? Because calculations, which fit to observed data, were very imprecise - they were made for different, though similar quantum theory. So now physicists puzzled, why so imprecise calculations fit experiment so perfectly.
