Looks like DirectX 10 functionality - unified (geometry) shader and like will be available in in the NVIDIA drivers very soon. Seems the entry points for new OpenGL extensions are already present in the driver nvoglnt.dll (96.89), including
GL_NV_geometry_shader4
GL_NV_gpu_program4
GL_NV_gpu_shader4
and new Cg profiles
All we need now is header file
Chances are, for OpenGL directX 10-like functionality will be here before VISTA. Another one for swith to OpenGL from DirectX. Also it will be at least couple of years before majority of the gamers switch to VISTA, but with OpenGL developers can utilize latest GPU to their full potential on the Windows XP.

From Wikipedia :
In computer programming, a hacker is a software designer and programmer who builds elegant, beautiful programs and systems.
It's possible that changing of the meaning of the word form positive to pejorative is the sign of how society see software developers. It's similar how in modern russian old word for "Jew" become offensive word, and it's modern form also sometimes used as offence (less so after the fall of communism)
There were anti-viruses in the past, which wern't relying on the virus signature only, but were trying to detect new, unknown viruses too. Dr. Web was the one, but it seems they dropped this feature later (or at least not advertising it any more). Probaly it was not cost-effective than. Seems the time have come to revive this approach again. Of cause it's not easy, require very sofisticated statistical learning, bayesian networks or neural networks, may be even genetic algorithms and very good understanding of underlying OS, but it may have become cost-effective again.
That is not "the solution" of the Navier-Stocks system - they could be solved only numerically (fractional element methods or other discretization), but this is the next best thing - proof of the existance of such solution. From the practical point of view that mean, if you have correct physical starting conditions and working numerical method you will get correct result after calculation. Until now, you couldn't have been sure if you will get physyically reasonable result of numerical calculations, even if starting conditions would be correct.
Greenphone is 695$ vs D-Link 600$, open platform, SDK (though you seems have to buy Qtopia License for development), have BT, mini-USB, touch-screen, 128Mb flash vs D-Link 24Mb, 240x320 screen resolution vs D-link 176x220. Major advantage of D-link is WiFi
This advancement could create portable Free Electron Laser (FEL), coolest laser around. The most interesting thing of FEl is that it can have variable wavelength.
It can be tuned to just above the highest energy absorption line (the "K edge") of the chemical element, and that element can be used for total reflection mirror at grazing angles. Thus Lead can be used to create optic for FEL X-ray laser tuned to Lead K-edge. Effective X-ray laser becoming possible without any nuclear blast. And even portable X-ray laser.
X-ray laser may have range measured in light secondd, light minutes and even light hours, making possible to build high resolution X-ray LIDAR with ability to scan Pluton surface. And Laser Cannon with the same range too.
What massively parallel tasks would possibly need 80 cores? I can see uses for two, maybe 4 cores but what are advantages of 80 core chip as opposed to system with 40 2-core processors we can have now?
If we are talking about desktops/laptops only, all mathematically heavy applications, like
games - physics, AI

audio and video processing
software renderers (raytracers)

The solution is very simple, and I am amazed that TFA didn't at least mention it. The solution is not to base grades on such handed-in work. Instead, base grades on performance that you can ensure is the student's own. Higher (and lower) education have a name for this: exams. Conduct an exam under carefully-controlled conditions, and no cheating is possible.
And how exams are better than handed-in work ?
The problem is that the existing education system put to much attention on just remebering or collecting information. And with web and wiki around it's becoming too easy.
But the same apply not only to education, but to work too. It's a lot more easy to find relevant information on the the web now than ten years ago. The ways people collect information are changing, and the old education system is not coping with it.
The way out should not be more strict control of exams or sources used in the work, but putting more attention to teaching how to produce relevant results.
That is replacing hand-in works and exams with actual reseach, problems, exercises and projects simulating real proffetional expirience, and letting student use as much web as they want as if in real-life situation.
They cut and past references from the wiki or code from koders.com ?
But they will be able to do the same on their job too.
Of cause exercises should not repeat, but that would not be a problem if a teacher actually profficient in the field he teach.
There are some very effective free tools from Sysinternal.com :
1. Process Explorer - it's showing not only the list of process, but also their paths on the disk
http://www.sysinternals.com/Utilities/ProcessExplo rer.html
2. Autorun : showing all processes and services launched automatically on start, and allowing to disable them. Very usewful for temporary disabling DRM crap like cdac11ba.exe, temporary disabling google web accelerator on start etc.
http://www.sysinternals.com/Utilities/Autoruns.htm l
3. Rootkit Revealer - name speak for itself.

Other tools allow monitor access to files, to disk, TCP/IP traffic etc.
Major news agency can outsource thier reporting operations to "independent" reporters, who could send their reports encripted. Soviet Russia [:)] tried to enforce such a ban, during the time than there was no internet and international phone conversation were few and expensive, with very limited success. All that they achievd was that mostly worst and exaggerated news got out and created "Empire of Evil" image.
No, ray tracing is all about searching databases for ray-object intersections. That's what GPUs can't do at all.
Serious raytracers are tile-based anyway, that is using a lot of look-up tables. Processing of single tile could probably be fit into upcoming GPU with "unified shader architecture". But it wouldn't be efficient. GPU arn't designed for a lot of branching.
I for one usually finding SIGGRAPH paper interesting and sometimes useful. I've read TFA and found it mostly non-informative ranting.
There is one example of the unfair editor behavior in the article - surely not enough to condemn all the conference.
Auther of the article don't like preferred treatment of the "hot subjects". But that is quite natural - "hot subjects" is what most people interested in this moment. If other researcher/practitioners in the field are not interested in what auther doing, they can not be blamed for it.
From the other hand establishing a rival conference would only improve things - more paper, more possibly overlooked approaches, more ideas.
Why do we still need to construct massively parallel computing architectures at the platform level?
Better heat dissipation ?

Dark Matter Exists

· Score: 4, Informative
My understanding is that gravitational lensing here suggests that dark matter hangs out around "cold matter" or solid matter , but not "hot matter" like plasma
No, you have it backward. It's normal, "barion" matter is hanging around dark matter concentration. It's just attract gravitationally to it, the same way as stars grouping into galaxy. "Solid" matter - I think you mean stars, which are in no way solid or cold - differ from "plasma" - I think you mean interstellar gas. Interstellar gas is subject to electomagnetic interaction with other masses of gas, while stars are not - they compact and massive and fly stright through gas, like bullets. So what happens is - stars are attracked to dark matter concentrations, and move together, glued with them, while gas is delayed by interaction with incoming masses of gas - blown away by them.
I don't see any plans for free SDK, or open developers community, no support for open source and freeware applications.
It's not even close to Trolltech Geenphone.
Google your friend. ANAM (I'm not a matematician), but I'll try.
According to string physicist Lubos Motl the proof indeed important to string theory. The proof based on the flow on the manifold (surface), analogous to heat dissipation - Ricci flow. This flow deform metrics (distance between points of the surface). But this process also describe renormalization of worldsheet - how the physics of the worldsheet (surface which string drawing, moving in space and time) change with changing of the observation scale. That is how phisics of string change then the scale of calculation changed.

A lot of people did it during the first high-tech bubble, survived its burst and still working successfully. The only drawback is, that you salary is based on your current proffesion expirience, so if you enetring the tech job market in your 30's prepare to be paid as much as a fresh worker out of college/universety. Severe career changes in the later age (up to 50's) is a common place in tech job market both to and out of it.

I don't think it's X86. It's definitely some kind of ARM. My bet it's a TI OMAP dual core (second core DSP-only) with graphics accelerator.
So, how soon can we get Elerium-115 and start building UFO Defence ?
