  1. Re:First 3D games? on Sony To Launch First 3D PS3 Games On Friday · · Score: 1

    There are many types of 3D.

    One that we all know, is 3D projection on a 2D surface. This is what most games currently use.

    There is Volumetric 3D. This permits the display of any 3D object that fits within the confines of the display area. Such an image can be viewd from any angle. Think of say of 3D array of highly translucent LEDs. Better methods do exist though, such as at least one that uses pulsed lasers to create individual spheres of plasma suspended in the air.

    There is stereoscopic, non-immersive 3D. We should all be familiar with this too, and this is what is currently all the rage. This usually requires special glasses, although there are a few other techniques that can be used. (Unless otherwise noted, none of the rest of these require special glasses.)

    We have monoscopic semi-immersive 3D. This exists when there is a 2D screen, where the image changes based on the angle you view the screen from, providing a "window" into 3d scene. This often uses head-tracking technology. The effect would only work for a single viewer at a time.

    There is also steroscopic semi-immersive 3D. This is similar to the previous, except that the each eye sees a different image, so one gets both the stereoscopic effect and the immersion effect. This could require special glasses, but it is also entirely possible to do without that. Again this effect would only work for a single viewer at a time.

    There are more variations on the above, allowing for an arbitrary but fixed maximum number of viewers.

    There is omniscopic semi-immersive 3D. This has the immersion effect (moving the head gives different views), and the stereoscopic effect. Furthermore omniscopic semi-immersive 3D would work in theory for an infinite number of viewers (but the laws of physics do get in the way of achieving that). Holograms can produce this type of image.

    Finally we get to full-immersion 3D. This is technology that requires a headset that tracks your head's movement. You can move or rotate you head in any fashion (except for the real world, which has this kind of 3D without a headset), and see the same results as you would intuitively expect based on your experience in the real world. This could be done either monoscopically, or stereoscopically, but in practice, this is almost always done stereoscopically, since if you are going to produce an expensive headset, you might as well spend the bit extra to make it stereoscopic.

    Generally not necessary. A surgeon can invent a new procedure, and try it out on you, assuming you give informed consent, and he has a reasonable expectation that it will work better or more likely be successful than the existing procedures. Granted if his expectation was not reasonable he could lose his license, and potentially even be prosecuted if things go sour, but otherwise it is (generally) perfectly legal. The only reason stem cell procedures are different is that the FDA classifies stem cells as a drug.

    Indeed many surgical procedures evolve by experimentation, with little or no proper scientific study. Many major new procedures do go through scientific studies, but primarily for ethical reasons (wanting to be sure it is safe) rather than legal requirement. But changes to existing procedures rarely get much if any study unless they seem quite substantial. But it should go without saying that even changes that appear to be relatively minor could cause major problems down the road.

    Don't be absurd. The average Us citizen would have trouble making heads or tails of L/100km.

Similarly, the cost of purchasing say 7.13L of gasoline is something we Americans would have at least some difficulty figuring out, since we quote gasoline prices in USD/Gallon. The cost of purchasing 1.88 gallons is much easier to compute.

    The only way the proprosed change would make much sense, is if we started selling Gasoline by the gallon, labeling roads by kilometer, started labeling speeds by km/hour, and squiched car odometers to measure km, rather than miles.

    • as would the exact masks used to manufacture the chips, including the memory chips
    • Full specifications sufficient to fabricate the plastic shell, lcd, and any other component used would be included. They must be detailed enough that anybody familiar with fabricating that type of component could theoretically produce an indistinguishable product
    • The PCB files would be included
    • I would permit them to omit including instructions for simple well known components like widely available resistors, capacitors, and even LEDs, as long as the requirements for those parts are sufficiently specified, such as value, tolerance, mounting standard, wattage (for resistor), and information about required shape, and and the specific maximum current, and voltage drop for the LED. (There are for example multiple kinds of green LEDs, which have different voltage drops and current requirements, so they are not all inter-compatible).

    While I'm sure they have included at least some of that, I doubt they have included all of it. Particularly, I find it very hard to believe that instructions sufficient to recreate the LCD were included. I also tend to doubt that semiconductor masks for all used chips were included, even if they included the VHDL/verilog.

    Nevertheless, your bluray player probably does not have a web browser, so who cares if it has WebM support. It was never intended for you to play WebM videos by burning them to disc and putting them in your bluray player.

    The same logic makes WebM support irrelevant for TVs, Nobody has ever specified a way to transport WebM over coax, composite cables, component cables, s-video, or HDMI. Further very few TV have a web browser, so that is irrelevant.

  9. Re:Wrong People on FSF Asks Apple To Comply With the GPL For Clone of GNU Go · · Score: 1

    Let us say I wanted to provide an iPad port of a version of GNU Emacs that was released under the GPL V2.

    The GPL v2 allows me to distribute a derivative of Emacs only if I can give the users all of the rights the GPL grants. That is Section 7 of the GPLv2 Now when you make an iPad application you basically agree that you will only distribute the application to Apple (who will redistribute it to end users), and that you will not distribute the app in other ways or enable or permit others to do so. Thus my agreement with Apple would not permit me to even permit Apple to distribute the app in other ways. But the GPL says that if I cannot permit the recipient (Apple) the right to distribute in all circumstanced otherwise permiteed by the GPL, then I cannot distribute my Emacs derivative at all. If I cannot distribute the app to Apple, then nobody besides me can ever run the App, kind of defeating the whole point.

    That whole thing has nothing to do source code. It is permissible for an iPhone developer to post the source code on their site, since that does not enable others to distribute the app outside the app store, since the only way to build the app is though the SDK, and if they use that they agree to distribute it only though the app store.

    Applications for use on Registered Devices as set forth in Sections 7.1 and 7.2 above, no other
    distribution of programs or applications developed using the Apple Software is authorized or
    permitted hereunder. In the absence of a separate agreement with Apple, You agree not to
    distribute Your Application to third parties via other distribution methods or to enable or permit
    others to do so.

    That sounds scary, but posting source code is not distributing the application to third parties, nor does it enable anybody else to do so, as they cannot build the application without the iPhone SDK, which means they agreed to the same restriction, so they could only distribute via the App Store.

    The problem is that the resulting binaries are also covered by the GPL if the source is covered by the GPL. Unless the developer is the sole copyright holder of any GPL parts of the code base, when they try to distribute the binary to Apple, they are not able to give Apple the full set of rights, because of the agreement in place with Apple. Thus as a consequence of section 7 of the GPL, it is not permitted for the developer to distribute the application at all. (It is of course different if the developer is the sole copyright holder on the GPL'd portions, as they could give the binary's to Apple under any other license of their chosing).

    However, let us pretend for a moment that they worked out a deal with Apple such that they could grant Apple all the needed rights under the GPL. Apple would still be violating the GPL if they distributed it through the app store in the same fashion as all other app store apps because they don't distribute the source, and they place additional restrictions on the binary when they redistribute it, which is not permitted by Section 6 of the GPL.

    Lucid dreams though are fundamentally conscious dreams. All dreams involve some level of consciousness, or they would not register at all. Many though have very little consciousness. You are not in the dream making it more like a movie, or you are there but you are not really in control. Dreams go through a whole spectrum though through to basically full consciousness, where you are basically fully alert, you are able to think things through, etc. Any dream where you stopped and though things through would be one with a relatively high level of consciousness.

    Now of course I am abusing the term consciousness here, because consciousness implies awareness of surroundings and awareness of self (at least to the maximum level self-awareness occurs in the species in question). In such a state, you are aware of yourself mentally, just like in real life, but as far as physical self-awareness you are only aware of your simulated self, and the same holds true for awareness of surroundings.

    Technically such a state could be called "lucid dreaming", but you are correct that generally that term is used for dreams that have both lucidity [1] and awareness of being dreaming.

    As for gamers though, while I will not dispute the end effect of having more conscious or even lucid dreams, I will dispute the explanation. Gamers don't have more control over the environment. Games often give the player relatively little control over the environment, and have only relatively course grained control over the character compared to the real world. You are not likely to be able to use your empty gun as a melee weapon, or perform many other improvised actions, such as ducking into a locker to hide from an assailant, or hundreds of other things that one might have a reason to try but the programmers never thought about, or decided was not worth implementing.

    [1] Here I am using the original definition of lucidity meaning able to think clearly.

    Local TV may be free over the Air, but it really works best in cities and suburbs. Regardless, many people get the local channels through cable anyway.

    What I see happening generally with TV, is a move towards everything streaming over the internet.
    The idea beingyou pay for a service, and it gives you access to on-demand streaming of the entire back-catalog of most prime time TV shows, and other programs that largely follow the same format. Most regular TV shows would be watched in this fashion. On the air date they just appear in the list of streamable programming.

    Other programs would support live streams. For example most news programs would have live streams, as would the Weather Channel, sporting events, etc. Those that make sense to also have available on-demand, would be available that way after the live stream is concluded.

    Under such a system there would be no such thing as local programming. All sporting events would be national, (although pro sports may insist on black-out regions), and even local news programs would be available nationally, since it would actually be simpler to allow that, and really not add any cost.

    Now I recognize that this if it ever happens will take a while. It requires substantial Internet infrastructure upgrades, requires near universal broadband, and it would be opposed by local stations (who would do little besides create the local news broadcasts), the networks (the service would largely replace the networks), producers (thing will change the way funding works, and would definitely really hurt the sales of box sets).

    Never the less, we are already gradually heading in this direction, so it is still possible, especially if the networks chose to co-operate, perhaps creating this service as a joint venture among the Big Three and the Little One.

    Besides it is really the only chance the Television industry has, since there are already numerous unauthorized TV show streaming sites popping up, and they are far more convenient than tuning in at broadcast time, or even setting up a DVR to tape the shows. All those sites are missing is set-top box support.
