  1. Re:Same problem as all VR headsets ... on Sony Announces Virtual Reality Headset For PS4 · · Score: 1

    It doesn't rest on your nose. Sony's been doing HMDs for a while, they design around a padded headband that puts the load up top instead.

    It's not "faked stereoscopic vision" when you have one viewpoint for each eye, that's literally the entirety of stereoscopy.

  2. Re:90 vrs 110 on Sony Announces Virtual Reality Headset For PS4 · · Score: 2

    The FOV is decided by the lens they put in the eyepiece of the output device and a single variable in your graphics engine of choice. It's not a graphics performance issue.

  3. Re:going to be terrible on Sony Announces Virtual Reality Headset For PS4 · · Score: 1

    A game's FOV and a display's FOV are two different things. You can literally change the former with one line of code.

  4. Re:going to be terrible on Sony Announces Virtual Reality Headset For PS4 · · Score: 1

    This is actually a product of Sony's research labs, not "some big management guys", and as they outlined at the actual event, the prototype does something over a 90-degree FOV (105 is entirely possible) with 1080p resolution. The finished version will be somewhat better. Framerate will be decided by the software, not the hardware; you could write a PS4 game that ran at 120fps in 1080p quite easily if you weren't trying to make pretty screenshots with lots of pixel shaders, and the relatively low angular resolution of a VR display would support that.

    That's terrible. For research purposes, I'd like to know how he did it.

  6. Re:More evidence of lack of design on Camera Module Problems May Delay Samsung's Galaxy S5 · · Score: 1

    Apple's cameras aren't bespoke engineering; they're usually Sony ones, and I'd be terribly surprised if Apple's suppliers weren't engaged in similar engineering challenges themselves at the moment.

    You'd rather they re-did the statistics in such a way that it gave you the answer you want?

  8. Re:"Impossible to replicate" on Endeavor Launch Pad Being Rebuilt Piece By Piece · · Score: 2

    It's the launch stack, not the launch pad: the goal is to present the shuttle in ready-to-launch configuration, so plastic simacula will not do in some instances. The example they give is a bolt that would've taken a "six figure" sum of dollars to reproduce to its original specifications, which is used to fix the shuttle to its external tank.

  9. Re:We need to stop big tax dodgers useing loop hol on Silicon Valley Billionaire Takes Out $201 Million Life Insurance Policy · · Score: 1

    You've got to balance having a tax system that's got loopholes, and having a tax system that's tied in intractable knots. You can at least fix the former by patching in exceptions and exclusions.

  10. Re:Do you realize that most batteries are recycled on EU Project Aims To Switch Data Centers To Second Hand Car Batteries · · Score: 1

    Li battery recycling is horribly inefficient right now; it's actually more resource-efficient to take cells that aren't good enough for cars any more (which have really, really high performance requirements) and use them in storage (which doesn't have such high requirements), because that way you're not producing more hard-to-rcycle cells.

  11. Re:The point of an exchange on OKCoin Raises $10 Million To Become China's Largest Bitcoin Exchange · · Score: 3, Informative

    1) If you want to use bitcoins, you have to buy some bitcoins. Originally you'd buy them either from a miner who was producing coins, or from someone else further down the food chain. That person takes your cash and transfers some coins into your crytographic wallet.

    2) If you want to make or receive a payment with bitcoins - transfer them to someone else, in other words - you simply send a transaction out onto the bitcoin network, transferring the money between the wallets as approved by both parties.

    Both of these processes are slowed down by the fact that the bitcoin network takes time to verify a transaction, passing the transaction around until it has been cryptographically set in stone. It's more convenient to have a completely ordinary bank, that pays in and out and transfers money between its customers' accounts rapidly, then balances its books with non-customers and other banks on the bitcoin network on its own time. That is a bitcoin exchange.

  12. Re:of course on EU Project Aims To Switch Data Centers To Second Hand Car Batteries · · Score: 1

    I've been to presentations about these systems; I can't remember the actual figures but used cells from various sources compare pretty favourably to best-of-class grid storage systems in terms of price, although the energy and power density is obviously pretty terrible.

  14. Re:Wait on Measles Outbreak In NYC · · Score: 2

    Unfortunately vaccination is one of those issues where their mistake (loss of group immunity) hurts someone else (endemic measles finds a ward of immunocompromised patients). That's why it's a social issue, not an individual one.

    I don't know if you've been following, but Andrew Wakefield fled the UK and doubled down on the crazy so I don't think you'll get any of those things out of him.

    The CIA used a fake movie to get people out of Iran, that doesn't mean Hollywood is just part of the intelligence apparatus.

  17. Re:Solution that might be a crime on Measles Outbreak In NYC · · Score: 2

    The whole idea of vaccinations is that they make it impossible for a disease to spread through a community, that it'll die in its current host before it finds another person who either didn't gain immunity from the vaccine or couldn't be vaccinated for medical reasons. You don't get that benefit at low coverage rates.

    I would love to hear how that was supposed to work. Were human beings programmed to irrationally love things created by people called Randall Munroe, or are you arguing that he owns some sort of mind-control ray?

    Those aren't changes for which practical data or experimental models exist, so he's unlikely to ever cover them.

    Unfortunately exchanges are the de facto way to work in Bitcoin now; without a cultural shift back to personal wallets, exchange problems are now Bitcoin problems.

    Skylab was pretty much done; future mission plans involved refurbishment. Just prolonging its existence would not have been productive.

    They engineered it so "no" doesn't work, unless you flat out refuse to ever let you kid use the tablet. If you say "yes" to one purchase - a reward because they've done their chores, whatever - then the tablet silently allows them to buy anything they want for the next 30 minutes.
