  1. Fake-out on Samsung Unveils New 10" Retina Display · · Score: 4, Informative

    Unfortunately, it's one of those nasty 'Pentile' displays, where subpixels are treated as pixels to inflate the on-paper resolution. If you treat them as actual useful displays where each pixel contains all the sub-pixels required to display the full range of colours (3 for regular displays, 4 for pentile, despite the name implying 5), then the actual resolution is lower than a traditional pixel layout.

    What the heck sort of media streamer are you using that can decode 1080p30, but not h.254? I wouldn't trust SSIM too much for anything other than comparing the output of the same encoder of the same source, and I can't imagine 1080p30 encoded as 6 mbps MPEG-4 ASP looking anything other than a blocky mess.

    Then don't even think about how much h.264 video is encoded 1-pass CBR to fit on a CD/single-layer DVD, rather than using a suitable CRF like a sane person. Or worse, how many people still encode with xvid for playback on anything other than a 10-year-old handheld player.

  4. Re:Send up a crew on Ugly Truth of Space Junk · · Score: 4, Interesting

    The creators of PlaneteS basically stated that they tried to get everything about oribital mechanics correct, except for the central premise of hiring people solely for collecting space junk, which would be massively ineffective and inefficient.
    I've always been partial to the 'puffball' technique: using a large (on the order of tens of kilometres in diameter when deployed), low mass loose mesh of fine fibres, with any incident debris vaporising the fibres and coming to a halt over a distance of a kilometre or so, without breaking it up and creating more debris.

    Except that looking at the specs It can decode h.264 high profile, something that most ultra-cheap players cannot handle. And as it runs linux, it can probably do so from a lot more container formats than vanilla .mp4 (finally, s standalone mkv player that can handle soft subtitles, ordered chapters and multiple audio tracks reasonably).

  8. Re:Happy 25th Anniversary!! on Chernobyl 25th Anniversary · · Score: 2

    That's really quite interesting. I know most heavy metals are usually boneseekers and poisonous in their own right, but yellowcake contains not uranium metal, but various Uranium sulfides, hydroxides, etc. I have no idea of the relative toxicity of these compounds. The radiation dosage from the unrefined, unenriched, and unirradiated Uranium would be so minute as to be inconsequential unless you ate a few tons of the stuff in one sitting.

  9. Re:Kind of silly. on The 'Three Ton' Hard Drive Destroyer · · Score: 3, Informative

    Even cheaper, but not as fast, is the ATA SECURE ERASE command. Wipes your data even better than DD (because it erases 'bad' sectors from the G-list too), and is built into pretty much every HDD manufactured in the last 6-10 years.

    The myth about '32 erase cycles' and similar nonsense about reading data with an AFM is pure bollocks, and has been since the introduction of MR (and later GMR, CMR and TMR) head drives nearly 20 years ago (15 for non-IBM drives).

  10. Re:Kill the Invaders on FPS Gaming and the 'Just-World Hypothesis' · · Score: 1

    I'm failing to see the connection to the Just-World effect: The effect involves seeing a perceived injustice, and assuming that the victim has somehow done something to 'deserve it'. In the case of a video game, the injustice is not observed, but perpetrated. Indeed, playing with the justification for self-committed acts can result in interesting results, e.g. Shadow of the Colossus, where there is a disconnect between the overarching goal (revival of Mono) and the actions of the player (wholesale assassination of ancient beings). The Just-World effect in Homefront would be more to do with those the OPFOR are abusing; the effect would theoretically cause players to assume the victims of displayed atrocities were somehow at fault for it.

  13. Filtration on 30 Years To Clean Up Fukushima Dai-Ichi · · Score: 2, Informative

    Wait a few weeks for the Iodine to decay, filter out the Ceasium and any inert heavy metals that might have been picked up. Pump now pure water into sea.
    As for the storage barges: they're only intending to store lightly contaminated water in them (to make room in the internal tanks for more heavily irradiated water), so irradiation from decay will be minimal. A good rinse should be sufficient to clean them of any radionuclides hanging about.

    "Scavenging for copper" is a euphemism for exactly this. The only copper you find 'just lying around' is copper being used for power or data transmission.

  17. Re:Incompetence on Crack In Fukushima Structure May Be Leaking Radiation · · Score: 5, Informative

    I think it's been handled pretty well. Nobody has been killed by DEADLY ATOMS, and the only radiological injuries have been skin burns to two workers who ignored their dosimeter alarms. The release of radionuclides into the air has been minimal, and the amounts found in food and water have dropped back below minimum levels in all but the immediate locality to the reactor complex (and the levels there are only above the 'constant yearly exposure' maximums). Reactor core and storage pool temperatures are again under control, and coolant water containment in all but two reactors is unbreached. In one of those, the leak of irradiated coolant is within the reactor complex.
    The 'crack' mentioned in this case is not in the reactor containment itself as the summary and article imply, but in a water storage pool next to the sea, with the crack being between the pool and the sea.

    Not that lessons can't be learnt from this: gravity-feed coolant reservoirs would be a good idea, as well as separate backups for the storage pools and cores, but it's far from "getting steadily worse".

    Hard to tell whether this is anything new or not when the article makes such glaring errors as:

    While some traditional prosthetic arms move via myoelectric motors and relays

    Myoelectrics involves sensing muscle movements by the electric fields generated, and is nothing to do with a type of electric motor. I doubt if anyone has used a relay in a prosthetic limb for at least a decade.
    If they really just using an EEG headband to control the arm, it's going to have very low controlled dexterity, and extremely slow response.

  24. Re:Before everyone freaks on Things Get Worse at Fukushima · · Score: 1

    Last update from the IAEA incident report page Is that the Unit 2 RPV well temperature remains stable at just under 300C, with pressure little above ambient. That doesn't square with a "molten corium breaching RPV" scenario, where temperatures would be a few thousand C at the RPV well, and pressure would rise as the molten corium dripping onto the concrete drywell causes outgassing.
