  1. Re:nitpicking physicist here on Google Invests In World's Largest Solar Power Tower Plant · · Score: 3, Informative

    No, it's going to collect a lot more than 392MW of solar power, if wants to put out 392MW of electrical power.

  2. Re:Correlation is not causation on Requiring Algebra II In High School Gains Momentum · · Score: 5, Insightful

    I hear the complaint "teachers will teach to the exam" all the time as an argument against standardized testing. Damn right they will. If this results in a poor education, it means they weren't good exams (e.g., the SAT). I had standardized exams at the end of my secondary education and we had to know the material damn well to do well on them.

    "Teaching to the test" is a talking point, not a valid criticism. It presupposes the system will be implemented badly. Anything and everything will fail when the execution is poor.

    Apple accepts this app and they're attacked for being anti-gay, supporting homophobia, etc... If Apple rejects this app, they'll be attacked for infringing on free speech, supporting a particular political agenda, etc... Either way, you're pissing customers off.

    But all I feel is schadenfreude. They got themselves into this mess by imposing editorial control over the iPhone in the first place. They made their bed, now they get to lie in it.

  5. Re:Easy Fix on Last.Fm Founder Criticizes Apple Over Music Subscription Fees · · Score: 3, Informative

    No, just no. If your profit margin is less than 30%, a 30% cut to per subscriber revenue means you're losing money on every customer, before any fixed costs. You can't just "make that up in volume".

    If you loose $0.50 on every customer, and you have 1 million customers, you just lost $500,000. If you try to make that up in volume and sign up another 9 million customers, you're now losing $5 million.

    70% revenue for a customer pool of millions of iPhone and iPad users is better than 100% revenue for zero of them.

    It's not when you only have a 5% profit margin. When you're losing money on every unit sold, you can't "make it up in volume."

    So WikiLeaks is angry that their former member stole 300,000 documents, and plans on leaking them to the world? That's the finest example of irony I've heard all week.

    It's also the finest example of organizational inertia I've encountered for a while, where an entity is created to further some basic principle, but slowly mutates into something more interested in its own survival and aggrandizement.

    To quote Dogbert, your comment more or less says "Hey everyone, I don't understand what fungible means."

    It's unlikely that much Saudi Arabian crude ends up in your gas tank. Your car is filled mostly from Gulf, Venezuelan and yes, Canadian crude. But it's still an international market, and a shortage of Saudi Arabian crude will drive up prices everywhere around the world, as European oil companies start looking to buy from elsewhere to make up for the shortfall.

  13. Re:Propaganda on DARPA Wants To Know How Stories Influence People · · Score: 3, Insightful

    It's not just propaganda. Most people think narratively, not logically. Instead of based on whether the facts and evidence are consistent and logically support a hypothesis, most people try to slot the world into stories they've heard, or believe in. Stories shape the way people think in powerful ways.

    Consider the /. post a couple down from this one Secret Plan To Kill Wikileaks With FUD Leaked. You've got people jumping on the notion that Wikileaks' recent problems are the result of an orchestrated plan to destroy it. Of course, logically, the facts don't fit, the timeline is all wrong. But people will believe it anyway, since it fits a narrative structure they've learned from books and movies and other sources of fiction.

  14. Re:Break out your paper maps and compasses on 4G Broadband May Jam GPS · · Score: 1

    Zero-visibility landings use ILS, not GPS, which is broadcast from a calibrated ground transmitted next to the runway. ILS operates at ~110MHz.

    In general we've been using radio navigation in aircraft long before GPS became widely available. Lookup VOR and NDB. GPS is useful for aircraft navigation, since it lets you take more direct routes than strictly following the VOR/NDB defined airways. If GPS became useless, it would make air travel more expensive (and less fuel efficient), but planes aren't going to be dropping out of the sky or crashing into mountains.

    And how is the law going to stop you from buying a car again?

    The simple fact of the matter is, in today's world, most people need a car to get by. If you tell people they can't own a car, they're just going to own and drive illegaly. They've got bills to pay, and are unlikely to get caught.

    Ignition interlocks may not satisfy your moral righteousness, but they accomplish the goal (i.e., keeping drunk people off of roads) far more effectively.

    Okay, so Facebook sets up the http login page to redirect to https. When you go to login, the MITM proxy connects to the https login page... but doesn't redirect the client.

    So how does HTTPS help? Without even getting into the issue of malicious CAs, HTTPS only protects people who connect to HTTPS directly (i.e., they type in https://www.facebook.com/). If you're relying on an HTTP redirector, you're fucked.

    Well, it's all control theory. If all you want to do is something stupid and trivial like balancing an inverted pendulum, then the math isn't too hard and the algorithm is comparatively simple. If you want to do anything more complex, then you have to start using more complex math.

    It's not so hard to turn the 'inverted pendulum' into a more complex case where simple trigonometry and algebra doesn't work: mount your pendulum on a turntable.

  23. Re:Running the numbers on Biotech Company Making Fossil Fuels With a 'Library' of Bacteria · · Score: 5, Informative

    If you consider total consumption, not just imports, it would require around 15,000 square miles. However, the US has over half a million square miles of active cropland, and about 135,000 square miles just corn.

    In other words, if you replaced ~3% of America's farming, or 12% of America's corn production with this type of hydrocarbon farming, you could replace all of America's oil consumption. Stick that in your corn pipe and smoke it, corn-based-ethanol producers.

  24. Re:Venue choice? on Google Submits VP8 Draft To the IETF · · Score: 4, Informative

    The IETF is the correct body for something like this, not ISO.

    ISO is a standards body, and the function of a standards body in every other industry is to take multiple incompatible implementations of a concept, figure out the best of each and combine them into a single common standard that everybody can support. Politics are an inherent part of it, since the entity whose current products is closest to the eventual standard stands to do well financially. Look at how OpenGL is developed, for an example of a proper standardization process. Companies implement the standard, then add extensions to provide new features and give themselves a competitive advantage. Then at the next standards meeting, OpenGL is enhanced to a common base by taking these extensions and making them part of the next version of the standard.

    But for some bizarre reason, software types view standardization as just a giant design process (except design by committee, an extremely political committee). If HTML and CSS were to follow normal standardization procedures, for example, Firefox, Opera, Chrome, Safari and even IE would be free to extend HTML however they want, and then every couple of years the best extensions from all would be combined and rolled into the next version of HTML.

    The IETF is the correct body for VP8, because VP8 doesn't need standardization. There are no multiple competing implementations that need to be brought into alignment. It exists, it works, fait accompli. This is the process by which most successful Internet protocols were created. Maybe in the future when people have new ideas about how VP8 can be enhanced, it'll need a standardization process. But for the time being, all we need are the details, published openly and clearly, so anybody can implement it.

    Standardization is about evolution, not intelligent design.
