  1. Shorten battery life by monitoring on Ask Slashdot: How Many of You Actually Use Math? · · Score: 1

    One complication -- if you start applying higher mathematics to calculate the battery life, don't you end up decreasing the battery life because you're invoking more processor intensive (and therefore power-intensive) calculations to monitor it?

  2. Obviously it wasn't the One on NASA Morpheus Lander Test Ends In Explosion · · Score: 4, Funny

    But then, they can name the next lander "Neo" and see if they get better results...

  3. Why am I playing the game? on How Much Detail Is Too Much For Games? · · Score: 1

    Type of game makes a big difference. Is it a strategy/tactics game where I need to be able to discern the overall situation from the screen, and see past the individual pixels? Or is it an eye candy RPG where part of the fun is reveling in the cinematography? Or a casual game like Angry Birds where the visuals reinforce some basic fun/humor element?

    It's up to a game developer to figure out what the customers will care about and build appropriately; part of the trick to a blockbuster game is making those decisions correctly.

  4. People do this for free already on Managing Human Workers With an Algorithm · · Score: 2

    It's called "citizen science," expanding the concept of things like SETI at home to drawing on the mass capability of interested people.

    A good example is GalaxyZoo. People classify images of galaxies online.

  5. Re:Wires are not the issue. on Wireless Car Charger Test Starts In London · · Score: 1

    Transfer efficiency is an important point, but I might also be a bit concerned about heat generation; a lot of wireless inductive chargers I've seen for small devices like ipods and such do seem to generate a lot of heat, which doesn't always do great things for battery systems. The vandalism/weatherproofing issues are good points, though, and worth consideration.

    To be fair, I admit some bias. Every time there's a push for electric cars, I can't help wanting to play Rush's "Red Barchetta" pretty loud. I can see myself at either end of that: the uncle that lovingly preserves the outlawed sports car for his nephew, or the nephew who goes on a weekly race/drive just for the fun of it and has to outwit cops along the way, who are limited by their technology.

  6. Re:16 Megapixles on Discovery Channel Telescope Snaps Inaugural Pictures · · Score: 1

    Even for astronomy imaging, 16 megapixels isn't so impressive for "the fifth largest scope in the US." There are many amateur astronomers across the country imaging with CCD cameras based on KAF 16803 chips (4096 x 4096 pixels). Open an issue of "sky and telescope" to the pages where they present a gallery of readers' images, and you're very likely to see something taken with a 16 megapixel camera. They're high end cameras from an amateur standpoint, no doubt about it, but not super special. Think about it as being comparable to investing the cost of a used car in your hobby... the cost is around the same.

  7. Re:Macro versus Micro on Asimov's Psychohistory Becoming a Reality? · · Score: 2

    That was the point of "psychohistory." The idea was you can't predict the individuals, just the mass/net effect over time.

  8. It's only temporary on Asimov's Psychohistory Becoming a Reality? · · Score: 5, Interesting

    Even in Asimov's world, psychohistory only works on groups that don't practice psychohistory themselves. Harry Seldon only kept things from going off the rails by making the science die out, and by starting a Second Foundation of telepaths.

    Once someone starts making predictions from data aggregation more effective, the race will be on to duplicate or improve on it, and then nobody's prediction algorithms will work.

    Almost sounds like someone should write a dystopian Foundation book, where the mathematicians race to predict each others' predictive abilities (and of course, stop them!)

  9. How many bloody G's are there? on Sprint Finally Joins 4G LTE Wireless Race · · Score: 3, Interesting

    At some point, you'd think it might be more cost effective for the handset manufacturers to start using some form of software defined radio to allow handsets to switch between different bands. Or at least some sort of FPGA solution reprogrammable by something like a firmware update. I suppose there might be some antenna inefficiency as you start switching away from what your antenna is tuned for, but I'm not sure how much.

  10. "cheaply produced" on High Security Handcuffs Opened With 3D-Printed and Laser-Cut Keys · · Score: 1

    Materials might be cheap, but if it requires both a laser cutter and a 3d printer, that's not exactly what I'd call cheap to produce.

  11. A keyboard, how quaint. on First Look: Microsoft Office 2013 · · Score: 1

    As long as my colorful touch panel has MX cherry blue buckling spring switches, I'm ok with that. Oh, wait, that doesn't work? Never mind. I'll take the quaint keyboard, please.

  12. Re:No worries on Solar X-Flare Blasts Directly Toward Earth · · Score: 1

    Unfortunately it does carry a certain amount of angular momentum from the rotation of the sun, so the CME doesn't quite travel in a straight line. It's mass that's moving, not just EM/light, otherwise it would be here 8 minutes after the flare (since we're 8 light minutes away) and the mass carries that momentum. The sun doesn't rotate uniformly, it's gaseous and the poles tend to rotate differently than the equator (I think less fast than the equator but can't recall for certain) but the flare originated from closer to the equator as many of them do.

  13. Reliable indoor positioning is probably one of the key pre-requisites to building workable augmented-reality apps like games and such. There's probably a real payoff for the long term, but maybe not for the group that invents the underlying concepts/tech, unless they find some way to see it through to applications.

  14. Re:Lame article on Student Creates World's Fastest Shoe With a Printer · · Score: 2

    It could at least specify what the 3.5 percent improvement is in comparison to. Otherwise it's pretty meaningless to make a "fastest shoe in the world" claim.

  15. Missed it by that much on Student Creates World's Fastest Shoe With a Printer · · Score: 1

    Everyone knows it's supposed to be a shoe *phone*, not a shoe printer.

  16. Obligatory Doctor Who observation on Nanotech Surprise: Shooting Lasers at Buckyballs Makes Them Bigger · · Score: 1

    Well, we now know what "living metal" the Robot was made out of in that old Tom Baker episode. They shot it with a laser, and it grew. Ergo, fullerenes.

  17. I'm getting confused on Activision Turning The Walking Dead Into a First-Person Shooter · · Score: 1

    From the sound of it, I almost thought "The Walking Dead" was based on a FPS to begin with.

    Heck, next they'll want to make a game out of that awful "Battleship" movie. Oh, wait...

  18. "And it's critical to finding the Higgs Boson" on Is Python a Legitimate Data Analysis Tool? · · Score: 1

    This story seems like an echo of the one a day or so ago about Linux being critical to the success of the LHC. Something with generic programmability supports something specific, then gets discussed as a tool for that specific task. Probably a lot of the comments there apply here.

  19. Re:It will be a shame if our first contact... on Copyrights To Reach Deep Space · · Score: 1

    Worse, the expected response might be for aliens to transmit the contents of the record back to us, to show us they're intelligent and want to start a chain of communication. Oops, but that would be considered a crime?

    You know, some sci fi writer with the right wit (maybe Scalzi?) could make a really good spoof short story out of this one.

  20. Creating a hazard on Headlights That See Through Rain and Snow · · Score: 1

    Should work fine, until the system decides the chrome-plated car driving in front of you is a glare hazard, and decides not to illuminate it...

    Personally, I think Infrared cameras are a better solution; the wavelength is long enough it goes around a lot of rain and snow. Some cars have these already, but they need to make it more standard/affordable.

  21. Re:Sounds a little hokey on Is Being In the Same BitTorrent "Swarm" Equal To "Interacting"? · · Score: 1

    Wouldn't quite go that far... more like saying you and your neighbor are both being prosecuted together rather than being tried separately because you both used BT. You may be right about it holding up, but I would see the question more as one of whether you're two individuals interacting with the same technical resource, versus two individuals interacting with each other.

  22. Re:Sounds a little hokey on Is Being In the Same BitTorrent "Swarm" Equal To "Interacting"? · · Score: 2

    Sort of, but in this day and age, don't many carriers use packet-switched comms rather than circuit based for long distance telephony anyway?

  23. Sounds a little hokey on Is Being In the Same BitTorrent "Swarm" Equal To "Interacting"? · · Score: 5, Insightful

    Did you interact with someone if your telephone call to party A was carried on the same transatlantic phone cable as someone else's call to party B?

  24. Eek, a global warming thread... on Exxon CEO: Warming Happening, But Fears Overblown · · Score: 1, Insightful

    I hate to say it, but sometimes the global warming topics get difficult to read. The topic is sort of an instant ticket to 800+ posts with high-tension opinions on both sides.

    Obligatory subthread arguments include:
    --the quality of the science (both for and against)
    --who's evil (whoever authored the story the thread is based on is a given, but who else?)
    --how dumb the public is
    --alternative energy

    Let's face it. Orson Scott Card was wrong. xkcd was right

  25. Re:Lots of applications on Scientists Keep Rabbits Alive With Oxygen Microparticle Injections · · Score: 1

    Or maybe super-deep dives, space station/vacuum suit emergencies...
