  1. Re:About launch mass on NASA's 'Inspirational' Mars Flyby · · Score: 1

    I never completely understood the need of launching massive ships from Earth whenever we want to leave it. Whenever we wanted to travel the seas, we did not build a massive caravel inland then painstakingly dragged it all the way to the coast. We reasoned it made more sense to build it in a dry dock, that way it only requires a tiny push to get it into the ocean.

    Wouldn't anyone at NASA think that making a "Space Dock" made sense?. Make a bunch of tiny trips to lower earth orbit and build the ship there, so you can make a larger ships to travel further. Mass would not be such a big issue (granted, fuel would be), but at least the escape velocity problem would be non-existent.

    Well, national space programs are not about exploring new frontiers. Military superiority and a corporate welfare program for defense contractors are about the only reasons that nation-states even pretend to have a "space program." NB: I'm not disagreeing with you -- if the US wanted a space program for exploration, that's what they should be doing, and as a tax-payer, I would be bitching loudly if they weren't. But exploration is not what the space program is for, so I don't bitch about it very much at all. With that said, if commercial exploitation of space-based resources ever becomes feasible, I would expect that nation-states will become interested in extending their ability to use force to protect claims on space-based resources. Should that happen, deep range manned missions might become a priority. Frankly, I'm hoping that Deep Space Industries succeeds in locating, mining, and returning valuable resources from space, and that some other commercial venture or nation-state sees their success and claim jumps them -- it's the only way I see to kick national space programs into gear.

  3. Hmm...what about an NDA? on Editorial In ACM On Open Access Publishing In Computer Science · · Score: 1

    Maintaining scarcity is a direct way to control the supply-side of the price v. supply curve. This is reason enough for companies like Elsevier to maintain a paywall. But there are other ways -- academic reputation has value as well, so it can be leveraged to help maintain the scarcity. It is conceivable that companies like Elsevier will begin to demand NDAs from submitters. Submitters will be faced with the choice of accepting the NDA in order to be published in a mainstream journal, or rejecting it and having to rely on non-mainstream journals as a vehicle for their academic credentials, which might put their academic careers at risk. NB: I'm not endorsing this tactic by saying it is conceivable, I'm only pointing it out as one way that Elsevier and their ilk could protect their business model.

  6. Re:Seems obvious to a naive engineer! on Spinning Black Hole's Edge Rotates At Nearly the Speed of Light · · Score: 4, Interesting

    In my limited understanding of these things, (mostly from articles meant for mass consumption, not scholarly journal papers), I imagine a black hole to be so massive not even light can escape its gravitational pull. Which technically means the escape velocity is the speed of light. So anything at the event horizon should be at the speed of light. This is of course, a naive view. The escape velocity is based on Newtonian, not Relativistic, physics.

    In Einstein's theory of general relativity, the Newtonian concept of mass doesn't really exist, being spread out over the Einstein curvature tensor on one side of the general relativity equation and the stress energy tensor on the other. Calculating the radius of a gravitational field where the escape velocity is equal to c is straight forward in both Newtonian mechanics and general relativity, and produce the same value, the so called event horizon (Scharzschild radius, technically) but something interesting happens when the gravitational field is generated by a rotating object -- it drags spacetime around with it. This would cause the orbital plane of an object to precess, something that Newtonian mechanics completely misses but was predicted nearly a century ago when people first started exploring solutions to Einstein's equations. Being able to directly arrive at the rotational rates of a wide variety of blackholes (which is what this announcement is all about) means that both frame-dragging and the no-hair conjecture concerning the characterizability of blackholes with just three Newtonian values -- mass, charge, and angular momentum -- can in principle now be studied more rigorously.

And to put not too fine a point on it, it is the case with all of their allies as well, in case relations sour with one of them. That's what being a superpower means -- you can project force where you need to, including your own backyard. The possible exception is China, who is neither friend nor enemy to the US right now, and possibly has already achieved at least technological parity with the US, if not social or economic parity. China is the biggest hurdle the US faces in the forseeable future; it will be interesting to see what the US does to prevent them from achieving social and economic parity with the US.

    There's a reason the phone companies charge so much per text message, and a lot of it has to do with paying micropayments to themselves every time someone makes a micropayment on sending a text message. The transactional overhead is very high.

    Anything you pay to a carrier for text messages is pure profit for the carrier, because there is no transactional overhead at all, either in terms of accounting or bandwidth. Incrementing a counter in your account every time you hit send and storing the result is trivial in terms of processing and data storage. Text messages are sent on an administrative channel that is separate from voice and data, and not over the bandwidth that they actually charge you for. The admin channel was built into the cellular network for control of the network hardware, and it was bought and paid for when the network was put into place decades ago. If you actually pay your carrier for text messaging, you are being exploited, period.

    Also, VR will make a massive comback if, as I suspect, Google Glass takes off and competitors crop up. This isn't a new idea, since Steve Mann has been wired for VR since, what? The 80's? I think its time has come.

    You are confusing VR with AR. Augmented reality systems like Google Glass simply overlay information about our environment in our visual field -- it doesn't replace reality like a VR system is supposed to, it just augments it. Augmenting reality *is* trivial, and the solutions are easily within the domain of current and near-term forseeable engineering technology. Functional VR, otoh, means directly interfacing with the proprioception/kinesthesia network in human neural anatomy that tells the brain what the body is doing in relation to other objects in the mental model of the environment. Modeling those other objects is trivial, as most VR researchers, including Carmack, will assert, but VR researchers are going to also have to figure out how to intercept, decode, modulate and retransmit the electrical impulses traversing the PK network that represent your body's position relative to those objects, which is decidedly non-trivial, especially while suppressing the original signals telling your brain that you are actually motionless, and even more especially doing it in a reversible way. These solutions, IMHO, require way more knowledge of human neural anatomy than we presently have, and will require the invention of new bio-engineering technologies to exploit it once we have that knowledge. AR has a distinct market advantage right now, so I'm certain Carmack and other VR researchers will turn their ingenuity to AR and away from VR, once they realize this.

    You are half right. (100% right about the RIAA, btw, but only half right about search engines.) A search engine is a content delivery service, period. It is supposed to generate profit by delivering search results, the same way Netflix/Unbox/Hulu generates profit by delivering movies and TV shows. The minute you let your customers control their end of the delivery pipeline is the minute you've lost control of your business model and can start kissing your profits good-bye. Google makes money by selling advertising content mixed in with those search results -- if Google allowed you to arbitrarily filter those search results, companies would stop paying Google to insert their ads into your search result stream. End-to-end control of the delivery pipeline is absolutely necessary in this business model. The entertainment industry learned this the hard way, when their customers discovered they could get the same content via the simple expedient of finding somebody (hello, Google!) who had a copy of the content they wanted. This is the single most important lesson to be learned about content delivery via the net. Information may want to be free, but in order to make a profit on it, you have to constrain it by making it available only to those people who can pay for it, and you can only do that by making certain that your customers can't go elsewhere for it, which is what the entertainment industry epically failed to do (an error that it is fighting desperately, via the loathsome RIAA and MPAA, to correct.) If Google loses control of their delivery pipeline, which is what you are advocating, then their business model is doomed.

    ...and I'm so tired of theistic arguments from otherwise apparently rational people. Self-awareness certainly makes it possible to assign some specific destination or goal for the system. But self-awareness doesn't confer any magical status to the system, selecting out a specific goal or destination for it simply because it is self-aware.

    Seriously -- self-awareness is within reach of any species capable of modeling its environment and then inserting a representation of itself into the model. Is a cat self-aware? Certainly. A horse? Absolutely. There is nothing noteworthy or astonishing about the existence of self-aware systems, so there is nothing astonishing or special about our species. A recursive function call is self-aware, for crying out loud. Well, it's self-aware 'til the stack overflows, anyway. :)

    By assigning some kind of magical status to self-awareness, your otherwise reasonable plea for a species-level sanity becomes a religious argument, indistinguishable from the "religious bickering" you are directing yourself to "evolve beyond." I think you are capable of appreciating just how ironic this is. What if your self-aware goal results in the extinction of your species?

Denying resale to protect your business model and preserve your profits is a rational choice, *especially* if making copies of your product is trivial, which is the case with software-based products, like video games.
