    Why not just board from the rear instead of the front?

  2. Re:Ray Tracing is *not* DOA on Intel Researchers Consider Ray-Tracing for Mobile Devices · · Score: 1

    Memory bandwidth isn't a problem with the appropriate architecture. The local cache memories for each group of N massively parallel cores can be updated via a broadcast. Heck, page-flipping (unfortunately using 2x the ram) would allow pipelining of the geometry updates so that access would be uninterrupted.

    SRAM can be made smaller too...

    I think what he means is "I don't want software that gets in my way because it tries to think for me". Sort of like autocomplete that alters the behavior of keystrokes (like tab) on the fly, clippy popping up and grabbing focus, etc. It's all about consistency.

    Automatic stuff/attempts at AI/wizards break consistency. Without consistency the interface becomes unlearnable.

    Any interface that can't be used without feedback is much harder to learn to use quickly, for example touchscreens and mice.

  7. Re:Where does the energy come from? on Nanoparticles Could Make Hydrogen Cheaper Than Gasoline · · Score: 1

    You get the energy to split the hydrogen from radio waves like Nikola Tesla suggested. However you gotta get that energy from somewhere, and that's an easy fix: just truck in coal from somewhere in Africa where they don't care about strip-mining. But the ships will be out of range of the radio, so run those on satellite microwave power. But the satellites need to be pushed up, cuz they keep falling see, so use a laser to hold them up. BUT, don't forget the laser needs power, so run it on that new clear power. The nuclear plant needs to keep its lights running so the operators can read the controls, so like burn fat from liposuction operations. Hah! two birds with one stone, we can get rid of all that ugly fat: Mandate only liposuction fat for new clear operations and it raises the price of it so high that EVERYONE will get liposuction. BUT, people will get so fat on the new McWendy Bell Tacoburgers that the cars will get less MPG, so oh heck I dunno add in like pedals or something... no that wouldn't work because that would mean people would get skinnier and the new clear operators would haveta run things in the dark.

    Hm I dunno... Naw I don't think it'll work at all.

  8. One to rule them all. on EU Funds P2P-Based Internet TV Standard · · Score: 1

    Instead of using Usenet news, Bit-torrent or Multi-cast, why can't we combine the features of all of the available protocols?

    Usenet news is not real-time, and Bittorrent is too inefficient, Multi-cast is not supported by all ISPs.

    Upgrade Usenet news to handle real-time channel subscriptions, bandwidth slot allocation, add multi-cast options, and support p2p style channel discovery.

    Bandwidth allocation determines what you are guaranteed to see real-time, everything else is done on an available bandwidth basis. What I mean is if you are watching a show live, it is guaranteed not to have gaps, but if you want to download 5 stream sections you missed from last week, the server might not have the bandwidth to serve you all 8 of them real-time, so would instead download them at slower speeds, allowing you to continue watching the two shows you had scheduled for real-time viewing.

    Having the multi-cast part of the protocol optional allows smart ISPs to lower their bandwidth requirements, while still allowing adoption of the protocol regardless of what the hostile or clueless ISPs support.

    P2P additions: This gets around channels not supported by the local ISP. So they don't want to support Usenet+? Fine, subscribe to an external premium encrypted Usenet+ server and they will be be punished by having their bandwidth support costs increase. Conglomerate the different sources together into one view similar to the way some newsreaders will combine messages from different servers.

    Encryption: Not sure how to leverage this in a useful way, but should be a way to enable it. Doing it securely would negate multi-casting (I think).

    Advantages:
    - Backwards compatibility: Any old newsreader can still use the service.
    - More efficient than Bittorrent when multi-cast is being used.
    - Unlike pure multi-cast, old data is cached, allowing you to get something that you missed.
    - Pre-scheduled broadcasts can be preloaded at off peak hours.
    - Reruns or repeats within a certain amount of time don't need to be resent.

    He's exactly right. Add in SMS logging and unified contact management (Cellphone phonebook synchronization + email address book, etc) and you have a huge winner.
    Using this approach the message could arrive via a window showing a virtual aggregated IRC/sms channel the user was talking in, or if the user was mobile and the message was urgent could arrive via SMS to his phone. Heck, both of them could be using SMS and neither of them would know or care whether the other was online or not.

    It's not quite the way you describe.
    It's like you go place a reservation on the property in your name in order to prevent some third party from getting buying it before your client does. However, by doing this you also prevent your client from using another agent to buy the property.

    I'm describing the Network Solutions tactic, not anyone else. Were you saying that NS will refuse to sell it to you while they squat on it or take it over as their own? I hadn't heard of any cases of them doing that.

    I still think their practice is at best highly questionable, and most likely predatory, but just wanted to make sure that their practice was being accurately represented.

  19. Re:Noise and price issues? on Reaction Engines plan Mach 5 Airliner · · Score: 1

    Hydrogen injection has nothing to do with engine design.
    It's the concept of sheathing the projectile in a thin layer of a light gas, such as hydrogen. The speed of sound in hydrogen is higher than the speed of sound in air due to its being 14 times less dense, so you have less of a problem with heating. The above link says it "reduces noise", so I was wondering if it could be employed on aircraft to reduce the sonic boom.

    Refraction wouldn't be such a big deal if they use the Adaptive Optics that astronomers use. And besides that, that plane mounted laser would be fired at 30k feet, well above most atmospheric distortion.
    Given that the Laser bearing plane is flying at 30k feet, and the hypersonic plane is at 80k (ala SR-71), there wouldn't be that much atmosphere up there anyways. If it truly is a problem, redesign the defending plane to fly at altitudes closer to the hypersonic plane.

  25. Shooting Games on Namco Blames Wii for Arcade Closures · · Score: 1

    Probably the reason they have so many shooting games is because no-one makes a PC or console light gun. The gun interface is so much closer to the real thing than a mouse when I find a good one I enjoy playing it. Anything else I can use keyboard/mouse for. Another reason for the arcades slide is that the multiplayer/community itch is scratched by good cooperative play on PC games on the internet & XBox live. And yeah, that whole dollar for 2 minutes of playtime bit is ridiculous.
