    We are Anonymous. We are Legion. We do not forgive. We do not forget. Expect us.

    Sorry, I meant to say we're Anonymous Coward.

    Early hands-on seem to agree that the controller is really comfortable. For example Ars Technica.

  3. So much for research on Verifying Passwords By the Way They're Typed · · Score: 1
    There has been commercial software for this for quite some time, for example see Authenware.

    It's probably already patented.

  4. Re:better than a group of doctors?!?! on Invent the Medical Tricorder, Win $10,000,000 · · Score: 1

    This has already been done by an Australian. It's a micro-lab basically. It was on a TV show called The New Inventors where inventions are showcased.

    Maybe if they learnt to use a decent search engine they'd have found this:

    and this:

    Looks like an Aussie gets the $10m.

    Actually the thing you refer to still needs a doctor to make a diagnosis. The X-prize asks for the device to make the diagnosis, this includes analyzing all symptoms, not just running a few tests.

  5. What about storing some energy? on Human Powered Helicopter Aims To Break Records · · Score: 1
    Most of these designs use only immediately available energy. What precludes them from storing some of it to achieve the 60s + 3m goal? Or is it forbidden in the Sikorsky price rules?

    You could have someone pedal the thing for a couple of hours to store energy before attempting the flight.

    I don't think it's easy, but it might open up some interesting possibilities.

  6. Re:Changing TV channels on The Insidious Creep of Latency Hell · · Score: 1
    That's to show the video. But why I have to wait for the keyframe to change the channel?

    If I want to jump 3 channels up I have to wait for 3 keyframes in 3 streams. I just don't care about the intermediate ones. It's just shoddy programming.

  7. Re:Mission Accomplished on Osama Bin Laden Reported Dead, Body In US Hands · · Score: 1

    No, it will probably get nastier for a short while. But the message is clear: We won't forget, even if it takes 10 years, we will not back down.

  8. Re:Oh my... on Sludge In Flask Gives Clues To Origin of Life · · Score: 1

    I still don't get the whole creationism vs science thing, it's a very American thing it seems. Thomas Aquinas solved the issue (at least for catholics) around 1220-ish (I don't have the exact date, so its an approximation) with its five ways.
    His arguments are based on on inductive reasoning (some are arguable, but anyway), his main argument is something like this:

    1 - Everything is caused by something else, nothing we can see causes itself (in reality he speaks of motion in an Aristotelian sense, but the complete arguments are long)
    2 - The causality relation cannot be extended ad-infinitum
    3 - Hence there must be an un-caused entity, that causes itself.

    He then jumps to call this entity God (here's something that is particularly arguable but to each it's own).
    The interesting thing is the use of what's called meta-physical induction. Even if we figure out what caused the Big-bang, we'll find something else, and when we solve that one, there will be another one, and so on and so forth. There is no conflict between creation and science, there's plenty of room for both.
    The way I presented the arguments has so many holes that you can probably fly a jetliner through it, but that's my error (it's a /. comment anyway). Philosophy has been dealing with these issues for centuries, there is much food for thought there.

  9. Re:Vote by SMS? on Ask Slashdot: Setting Up Wireless Voting For Students? · · Score: 4, Funny

    Why use any commercial solution at all? You're in a school after all. Make your students create simple buttons on your electrics class. You can just transfer the clicks via wire. Then make your programming class code the back-end system for a computer. Microsoft offers Visual Studio Express to students for free and you can easily get a cheap license to your school by calling Microsoft's sales team. At the same time your students will get real world experience and get to know the best programming tools used in the industry.

    Come on, you're a Microsoft sales rep., aren't you?

  10. What's the most common use on Naming Bi-Directional Streams In an API? · · Score: 2

    Think of use cases. What are the clients of your API be doing the most?
    What choice will cause the least astonishment to your users?

    This is a usability problem. Do what will confuse your user the least. Ask them if you have to.

    Write code for both cases against your API. Use it and see what works and what doesn't.
    There is no easy answer, this is a design question and aesthetics matter, hence it's rather subjective.
    In any case, take into account if your target development platform uses any conventions, and if so stick to them.

  11. They urgently need a new name on LibreOffice 3.3 Released Today · · Score: 5, Insightful

    I can't believe that the name LibreOffice stuck.
    I'm a native spanish speaker, and it sounds so goddam awful. Specially when mispronounced by pretty much everyone.
    I know this is a personal opinion, but still.

  12. Latency, latency, latency... on Thin Client, Or Fat Client? That Is the Question · · Score: 1

    Latency is always underestimated. I currently work on monster company that does all its development on hosted linux machines, so you basically have to use ssh+ some remote desktop (NX, VNC, whatever).
    This works fine if you are within a millisecond to the datacenter, but I'm currently ~200ms from it, and I tell you it sucks! Is almost unbearable. It so bad, that you get distracted while waiting for the screen to update.
    The worst part, is that most of the developers are in similar situations, sometimes worsened by limited bandwidth.

  13. Re:Aw. on DOS Emulator In and Out of App Store · · Score: 1

    They allow emulated code now, as long as code is not downloaded by the app. There is a fairly popular C64 emulator, for example. They might object the iName though.

  14. I have to agree on Too Much Multiplayer In Today's Games? · · Score: 1

    I never play the multiplayer portion of the games I buy, I try it sometimes, but the fun it's not there. The load times are annoying, you have no context or history (you're dropped in the middle of some mess without purpose), and if you die you have to wait to re-spawn. I don't see why anyone would want to spend so much time just waiting.

  15. Mottainai on Restaurant Tells Diners To Eat Everything On Their Plate · · Score: 2, Informative

    It's a very Japanese thing. It's probably based on the concept of Mottainai, where wasting something (such as food) is seen as wrong/immoral.
    The meaning is more nuanced than "wasting" but it is as close I can describe it without copying the entire Wikipedia page.

  17. Re:The Internet is less free... in Brazil. on In Brazil, Google Fined For Content of Anonymous Posting · · Score: 1

    Many countries consider freedom of expression slightly differently than the US.
    Argentina, for example, uses the criteria that no prior restraint is allowed. That is, the government cannot censor you before you speak (but it could censor you after the fact).
    In any case, in most countries freedom of speech does not imply that you are immune from slander or libel charges. You may speak your mind, but there may be consequences (usually depending on your intent and the veracity of your statements). Also, in many countries, anonymity is not a right.

  18. Re:12 year old product compares to iPad, and couri on The iPad vs. Microsoft's "Jupiter" Devices · · Score: 2, Insightful

    Just goes to show how stupid people actually are. Better doesn't always win.

    You're oversimplifying. "Better" is a relative term, it needs context to be meaningful. Apple does many things right that aren't easy to duplicate and can't be reduced as check-boxes on a feature comparison chart. Using a different context, I could say that iPad is actually "better", just because it sells more units.

  21. Re:Neutrino measurements here we come... on Simple Mod Turns Diodes Into Photon Counters · · Score: 1

    Having better neutrino detectors could pave the way for neutrino-based communications. This would be great for long distance communications (think Mars for example) given that neutrinos can travel very long distances without hitting anything. At least it would be fun to look for E.T. communications.

  22. Re:Natural gas is great fuel on Fuel Tanks Made of Corncob Waste · · Score: 4, Interesting

    You are forgetting that natural gas can be replaced by gas made from decomposing organic matter (i.e. trash), which is renewable (although the CO2 emmisions are still there, but it's the same with biodiesel).

    Adapting a regular gasoline car to natural gas, costs around U$S 700 in Argentina. The equipment pays itself after a year or so.

    The economics may be different in the US, though. For example, some year ago, before natural gas was widespread, we used a mixture of regular-gas and ethanol on some parts of the country (no modifications to the engine required, but as with natural gas, a thicker engine oil is needed). The biggest problem was that the fuel hoses and some plastics in the car worn out faster due to the ethanol.

    Brazil still has widespread use of ethanol mixed with the gas.

  23. Pipes are more expensive to install than wiring on Appliances Hog More Energy Than High-Tech Gadgets · · Score: 1

    No, the reason is economical in nature. Pipes for gas are more expensive than the equivalent wiring.

  24. It seems to works like an optical mouse on IBM Announces Wii Chips In Nintendo Hands · · Score: 1

    The 'sensor bar' appears to be just a IR led illuminator to provide a bright IR line of leds (something easy to detect, and that's why I'm gessing Halogen lights will interfere with the wiimote).

    The black window in the wiimote, contains a custom sensor, which seems to be a low resolution IR camera, plus some more circutry to detect the bright IR line (the black window is a visible light filter).

    An optical mouse works similarly. It has an illuminator, plus a sensor that actually is a camera (16x16 pixels typically) and some circutry that detects displacements in the image.

    So it's not that hard to do. Displacement is easy to detect if you have a clear pattern in the image (we already do it for optical mice), if you're too close to the 'sensor bar' the wiimote 'sees' that the line across all its field of view, and that complicates detecting displacement across the direction of the line.

    Probably the sensor has the added ability to detect rotations in the image, no just displacement.

  25. Well one case I know is the Mitsubishi Pajero on Both Sides of Wii · · Score: 1

    The Mitsubishi Pajero in Argentina has been rebranded as 'Montero'.

    Since 'Pajero' roughly means "a guy that masturbates very often / is horny all the time ".

    The choice of name for an international product is quite hard (name collisions are the worst part), and cultural differences can cause a disaster for a product.
