Submission + - Bird Flocks Shatter on Impact (sciencemag.org)

sciencehabit writes: A flock of birds flows like a liquid, but in one respect it acts more like a solid, according to a new computer simulation. Flocking birds can fly together as an impressive fluidlike mass, and a team of physicists wanted to know whether a flock possesses a cohesion similar to surface tension in a real liquid. So they used a computer simulation to fire into a wall a flock of virtual birds, each programmed with a bird brain that keys off the direction and speed of its neighbors much as an actual bird would. As the flock smacked against the wall, it shattered into uneven clusters as a brittle solid would, rather than splashing into equal-sized drops as a liquid would. The result suggests that, like a solid, a bird flock has no apparent surface tension even though interactions between the birds promote the overall cohesion of the flock. The work could help scientists decipher the dynamics of animal herds and other "materials" made up of active agents.

Submission + - New DARPA Program to Develop Prosthetics With Lifelike Sensory Feedback (gizmag.com)

Zothecula writes: Many modern prosthetic limbs are so intricate that they seem like something from the sci-fi cyborg realm. Unfortunately, to the wearer these marvels still feel like lumps of dead metal and plastic. DARPA's recently announced Hand Proprioception and Touch Interfaces (HAPTIX) program aims to change this. Using implantable sensors linked wirelessly to external modules, the goal is to provide lifelike prosthetic limbs with such a high degree of sensory feedback that they bring a sense of being part of the the wearer’s body, not something just strapped on.

I second this idea. If at some point the gov't becomes convinced bit coin is viable, they could just start their own new block chain . If they bless it with some sort of official "approval" (e.g. Their coin is legal tender for taxes), then that one can supplant any other. And as the parent comment mentioned, any sufficiently large market force can do the same. Eventually, bitcoin won't be the only crypto coin. And if the gov't can create its own competing coin, it can create two, or N, new block chains. thus, it can mint crypto currency just as with fiat money.

Comment Sony BD-S3100 (Score 1) 165

This is a combo DVD/Blu-Ray wifi internet connected device. I got it solely for the blu-ray player, but discovered how convenient the internet connection is. A netflix interface is built in. The remote control even has a "netflix" button. There's a tiny bit of setup that you can do, and after that, my over-70 mother can operate it just fine. It also has interfaces for hulu, vudu, and music services like pandora and slacker built in. I used to hook my laptop up to the tv to watch netflix, but no more. There's a selection of other lesser-known services available in the interface, too.

Comment A nugget with a menu of optional interfaces (Score 5, Interesting) 171

What I want is a computing nugget that I can carry in my pocket (on a necklace, whatever), and then carry any number of different task-specific interfaces to it. You don't even have to carry them. Just walk up to your desk, and your keyboard and monitor connect and you have a desktop. Pick up your "smart-phone" interface, and go. Pick up your candybar interface and go. But all the computing and storage stays the same. It's your cloud in your pocket. Sell me that HTC.

Comment Agents, not unions (Score 2) 761

What tech talent needs are agents, not unions. That is people to represent them in negotiations who are skilled at negotiating, and motivated to get a good deal. Very much like entertainers (actors, singers, sports stars). The agents focus on the "business" while the talent focuses on delivering value. This is especially true in job interviewing situations, especially when interviewing with a company that has a HR department. They have advantages in that interaction that are unbalanced. I personally would love to have an agent. The idea has it's hurdles, but no more so than the idea of starting a union.

If You Resell Your Used Games, the Terrorists Win 423

MojoKid writes "Game designer Richard Browne has come out swinging in favor of the rumored antipiracy features in the next-gen PlayStation Orbis and Xbox Durango. 'The real cost of used games is the damage that is being wrought on the creativity and variety of games available to the consumer,' Browne writes. Browne's comments echo those of influential programmer and Raspberry Pi developer David Braben, who wrote last month that '...pre-owned has really killed core games. It's killing single player games in particular, because they will get pre-owned, and it means your day one sales are it, making them super high risk.' Both Browne and Braben conflate hating GameStop (a thoroughly reasonable life choice) with the supposed evils of the used games market. Braben goes so far as to claim that used games are actually responsible for high game prices and that 'prices would have come down long ago if the industry was getting a share of the resells.' Amazingly, no game publishers have stepped forward to publicly pledge themselves to lower game prices in exchange for a cut of used game sales. Publishers are hammering Gamestop (and recruiting developers to do the same) because it's easier than admitting that the current system is fundamentally broken."

Comment Re:Well, they're a good indicator of intelligence (Score 1) 672

Hmm, this question is relevant to the few people, like me, who've found themselves in non-tech positions and wanted to move back. We even had a post here about this recently (here). The interviewer may have a legitimate concern about why your switching back, and whether you will follow-through or flip flop again.

Comment Re:This is an INPUT device (Score 1) 81

Actually, you don't need a screen, but if you stretch your definition of "something like that" you're on the right track. We have lots of input devices that don't have screens attached: doorknobs, handles, tuning knobs, buttons, switches, pedals. This could be imagined as an alternative to all of them. Put it on a piece of glass and you have an input device that lets painters "trace" pictures from real life, just like the renaissance masters.
