Shouldn't the industry be pushing further toward graphics cards that can accelerate true Phong shading, rather than shortcuts and texture mapping tricks?
No it shouldn't. At least not in the sense of special hardware. Modern card use programmable shaders, and it's up to a programmer, use limited GPU resource for Phong shading or other effects which could be more important at the moment (for example shperical harmonics lightning).
Or even automatic interpolation between meshes of different complexity depending on how much of the scene a particular model takes up?
Mesh of essentially different complexity usually have too different topology. This problem is very hard even on the theoretical level. In fact this article is the stub in that direction. In the trivial case of smooth,highly detaled meshes the mechanism already exist and used (part of DirectX) - progressive meshes.
All in all, very poor attempt to create a malware for Series 60. I am sure you can get much higher propagation by installing an autoexec worm inside of S60 warez releases.
That wouldn't be much more successful. Only user who installed warez would be harmed. Any attempt to propagate would cause the same "Unsigned application" warning and requiere confirmation.
There is a one word response to your theory, the virus, and you kind of shot down your own theory when you pointed out living organisms are literaly bathed in energy so nanomachines could use them parasitically to get energy.
nanomachines using parasitically energy of living organism would be virus - they will have the same energy source and the same limitations. Viruses are the results of two billions years of evolutions, and probably at the limit of efficiency of nano-scale replicator parasiting on living organism. So what we get as result is just another virus strain. Nothing special.
In a nutshell, if the Visby was 100km from an enemy vessel it could see the enemy on its radar but not vice versa.
I highly doubt it and suspect some sloppy journalism here. As soon as ship or plane firing it's radar invisibility is over. Anti-radiation missiles are in use from fifties, proven themself extremly effective in Vietnam, and can be homed on active radar (modern even on short radar pings). The stelth should be used only with passive detection/guidance means.
I did some devlopment for similar sytem - 4 videocard working in parallel, tiling the screen or time-dividing frames. To put it short - it's very difficalt to extract performance gain, require a lot of geometrical culling or synchronizations and other triks. Off the shelf game will not give 50% performance gain with such a system, 15% in the best case (and i doubt even that, and it would quite probably create artefacts) . To extract something similar to 50% would require a lot off efforts for developers, no develpers would want to do it to support a tiny market share.
They have one big advantage - Symbian OS still quite open platform. With GBA developer need corporate-scale money to license a game. With Symbian it's free (At least until "Symbian Signed" certification becoume mandatory). That mean there is a lot of hobby and part-time developers cranking 5-10$ games and of cause a lot of freeware. About controls and rendering quality - Of cause if yoy would try direct port of console/GBA to phone you get crap. Smartphones need games designed from the ground with controls and vertical screen in mind. Rendering quality could be quite good with carefull programming (even 3d). Check N-Gage titles - N-Gage have no dedicated graphics hardware, all N-Gage have is exactly the same CPU as Nokia 3600/3650 - 6600 (different RAM of cause, but that is not a limiting factor) So on common smartphone you can have N-Gage quality games, and some of them not so bad. IMO what stalling mobile games is not platform limitations, but low market penetration of smartphones themself (I suspect that the number of smartphone hobby devlopers not much less then number of smartphone gamers for now). Smartphones themselfs are the problem, most people can't figure what they are useful for...
Witness Chernobyl and TMI. And if they lied to John Wayne, they'll lie to you. Plutonium goes missing more often than they'll tell you. Who has it? Noone knows.
Only specially designed reactors can produce weapon-grade plutonium. (BTW Chernobyl was one of them). We are talking about completly civilian design. All modern civilian design are not capable produce weapon-grade plutonium.
First, dont't mistake Dark matter and Dark Energy. They are completly different beast, and have only in common (is it true ? no one know) that both are in the number of biggest(together with quantum gravity) misteries of modern physics. Dark matter is a problem of mass distribution in tha galaxies. Dark Energy is a reason why universe expansion accelerating. From the formal point of view it's no more than a constant in the equations of General Relativity. And I think you are right, it's not "real" acceleration, it's expantion - the volume of the universes increase. Take a baloon and mark several points on it. Now blow baloon and distance between points increase. That is like the universe expansion. And it can be in some sence be faster then speed of light (that is the distance between points invrease faster than light travel from one to another) without contradiction to General Relayivity I think, becase points are not really moving - only distance between them increase (but I'm not a physisists, so I can be wrong here)
First there are games which are work of art, "Planscape:Torment" for example. Averall there is a lot of art/music in the games, and some of that is not of bad quality. More important from educational point of view, videogames brought to public awareness quite a big layer of humanitarian knowledge, not accessable by general public before. Ask teenager of 70-s , who is shaman, where the Jotunheim is, and who were major opponents of Oda Nobunaga during Warring States period. What kind of answer would you get ? Now the situation is different. In the search of content developers digging through a lot of world history, culture and arts.
I agree about Nokia 6600 stability - I never had unintentionall reboot. I'm rebooting only while debugging (I'm writing symbian game). The only complain is I had to recharge every second day, but I'm running game on it about hour per day. Recharge pretty fast though.

I can only asume that online game distribution would be pretty easy to crack compared to cd copying.
Not easy if it's distributed to console like PSP. Sony can use model , commonly used for handhelds now: Customer give his unique device ID, server generate key from this ID , this key should be used to unlock application. For PSP server could also encript application with this key. Every time game running it check device ID and validity of the key.
For PSP this sytem would be even more hard to crack then for handhelds, because
1. AFAIK there is no easy way to get installed game form PSP to PC
2. crackability of the console game depend on availability of PC emulator. PSP SDK cost is 25000$, so it will take a lot of time before free emulator will be available....
Sony charge 25000$ for PSP SDK and god only know how much for license to produce game. So Sony probably will not overwhelm customers with numbers of titles on release. Nintendo already have GBA base, and if it would release free SDK and make it easy to get license it will attract a lot of small/indie developers. Of cause most of this games will be crap, but by sheer numbers there bound to be some gems among them. And numer of titels have strength in itself too.
From the practical point of view the version of OpenGL after 1.3 does not matter, because most of functionality are in extensions anyway. That make quite a mess, because if you are using OpenGL 1.4+ the same functionality present both in the extensions and the core.
Waht if e-mapping cappability lost during some major resque operation ? Like locating sinking boat ? So officers suddenly have to dig out paper maps, print out all relevant information and put it on the paper maps, all the while time ticking ? Still no danger to public safety ?
Damn dude, you're a dumbass.
Ever notice how GNU works? If you don't contribute, someone else will. It's great, you should try it sometime.
GNU is now a full scale meme, your ideas are old, like 1993.
For now GNU practically doesn't work for smartphones. There exist only about ten OSS projects for Symbian OS, and only one which I'd call really imortant (klimt - OpenGL ES clone). From the other hand number of shareware application count in thousands (if not tens of thousands) and even free though closed source app count in hundreds. It seems the main problem is that Symbian poorly documented, goes in sevreal different flavors, and there is not enough guru ready to disperce their knowladge for free. Would this change with Linux smartphone ? Probably not much : Each manufacturer will use his own kind of Linux, and woould build proprietary API on top of it (The sitauation with Symbian right now). This API will be a must to know before programming anything, will be poorly documented and will not be completly open (The sitauation with Symbian right now). Some manufacturer may even require money for SDK and license to write apps (the direction which some manufacturer taking with Symbian) They could do it because their API will not be GPLed. Yep and you will not be able to recompile kernel because it will be in the ROM.
Geforce4 Ti4200 had a lower power consumption and was faster in many cases compared to Radeon 9500. Still many opted for 9500 because it supported 2.0 shaders, while Geforce4 supported only 1.x shaders.
PS 1.0 vs PS 2.0 (vertex shader difference was not so big) is not the same as PS 2.0 vs PS 3.0
PS 2.0 was a whole new world of opportunities, plain impossible with 2.0 PS 3.0 also have a lot of new functionality, but it could be used mostly for development porpose, not for real applications, because full 160 instruction PS 2.x would bog down even X800/GF6800
The problem is, there is no hardware out there than can emit one and only one photon 100% of the time. I wouldn't be suprised if it turns out to be totally impossible to build hardware that does.
Such hardware exist for decades ago and called laser. Laser emits photons in the same quantum state, that in some sence "single" photon.
Yes for inventions and improvements this is a good idea.
But basic research is less product related.
What is the commercial value of knowing which way a helium atom spins, or how much closer we can get to absolute zero.
How that will later effect us we can't even guess at now.
The field of "basic research" wich can't have industrial output in the nearest 20 years is pretty narrow - high energy physics including unification attempts, cosmology, astronomy and mathematics. All the rest of basic research can produce industrial output any moment - nanotubes, buckyballs, DNA robots, quantum criptography, high-temperature superconductivity etc. - all this product of the "basic research" and quite product related.
The problem with AI , beside incredible techical and scientifc difficalties (Well, if we are not talking about sloppy path finding:) ) is that it's easy to market graphics, and difficalt to market AI. Screenshots(if they are not forged and shoe frame per second) and short demo is enouth to show publisher and prospective buyers that the game has great graphics. But how would you show off agreat AI ? The point of good AI is that it always behave at least sane, in all zillion of the game situation, and you wouldn't know it until you finish almoste all the game, and in this case you already bought it. Only MMORPG can market good AI, but they usually have more urgent problems - lack of content and bad balance. By the time MMORPG have enough content and figured balance it usually outdated and is not worth big investment. The only solution I could see is a middlware - third party AI engines, like physics engines sold now...
It's not always possible not to debug. Ever tryied programming multiagents systems ? The behavior of the system unpredictable (heh emergence), and it's quite often just plain impossible to tell why the system behave this or that way without debugger.

In google news: HANOVER, Germany (Reuters) - A tip from reward-seekers and information from Microsoft led to the arrest of an 18-year-old suspected of creating the "Sasser" computer worm, German police and the software giant said on Saturday. Spokesman Frank Federau for Lower Saxony police said police were certain they had the man behind one of the Internet's most costly outbreaks of sabotage. "We are absolutely certain that this really is the creator of the Internet worm because Microsoft experts were involved in the inquiry and confirmed our suspicions and because the suspect admitted to it," he said in an interview with Reuters Television. It was the lure of cash that proved the man's undoing. A group of individuals from Lower Saxony approached Microsoft (MSFT.O: Quote, Profile, Research) on Wednesday inquiring about reward money should they turn in the man. The U.S. software giant in the past has put bounties of up to $250,000 on the heads of other notorious virus writers. Microsoft general consul Brad Smith told reporters the company agreed to pay the informants if there is a conviction. "They did not stumble upon him through technical analysis. They were aware of who he was," Smith said, declining to elaborate on their relationship to the suspect and saying only the number of informants was less than five. The economic toll of Sasser may never be known, but it claimed some big scalps, including Germany's Deutsche Post (DPWGn.DE: Quote, Profile, Research) , Britain's coastguard stations and investment bank Goldman Sachs (GS.N: Quote, Profile, Research) . "COMPUTER FREAK" Federau said the man, who he described as a highly intelligent "computer freak" living with his parents, was arrested on Friday near the central German town of Rotenburg but was no longer in custody. Authorities and Microsoft said they suspect the man created all the versions of Sasser, adding he worked alone He is also believed to be a main person, if not the mastermind, behind the Netsky viruses that have been plaguing Internet users since February, Smith said. All the man's computers were confiscated by police, Federau said. Since appearing one week ago, Sasser has wreaked havoc on personal computers running on the ubiquitous Microsoft Windows 2000, NT and XP operating systems, but is expected to slow down as computer users download anti-virus patches. The computing underground responsible for hatching worms and viruses has proved a difficult ring to crack for law enforcement and security experts were surprised at the rapid arrest.
