I question why anyone would go that route for writing malware. When you start using the OpenCL APIs, your graphics cards will clock up and leave their low power states. The graphics card resource utilization (compute, memory transfers, memory usage) is shown by monitoring tools such as GPU-z and command line tools such as nvidia-smi. You can't hide anything on the GPU.
Well you could secure the wheel using some rectractable bolts during launch. Only when in orbit you retract these bolts and then you turn on your electromagnets.
I found quite a lot of research papers on magnetic suspension of reaction wheels. I really wonder why this isn't mainstream technology yet.
Isn't there any technology to keep reaction wheel discs floating in a vacuum chamber instead of using mechanical bearings? How about magnetic suspension and frictionless motor drives? This has to be possible with today's technology.
nVidia holds a lot of patents in the fields of graphics technology - it is a major player in this field and to date has a large market share in the desktop amd mobile GPU market. This is absolutely no patent trolling.
It's just the usual insane patent wars among major players in technology. I highly doubt this will go to court. There will just be a quiet agreement among the parties involved before this escalates too much.
I made a test order of one of these products for evaluating whether they are any good for mining. The 4 GB video RAM on the card and the supposed graphics chip on the card would have made a very good deal.
But it became apparent immediately that this was an outdated Fermi gerneration chip, despite the card being recognized as a GTX 660 by the driver. The card ended up on my scrap heap because it was useless for my purpose (high power consumption and low performance)
At the time I assumed it was some kind of OEM product (relabeling older chips under newer product names is very common in the GPU business). But the investigation of the c't magazine seem to indicate that there is some VBIOS tampering going on and that this is not happening with nVidia's blessing at all.
I'll be following the story closely to see what the outcome of this clusterfuck will be.
Can't one just subdivide (tesselate) polygons that appear relatively large in screen space so that they consist of many small polygons, with a few pixels each? This would allow for doing the barrel distortion entirely in the vertex shader with no ray tracing being required. The challenge is to perform the dynamic tesselation without requiring a constant updating of the geometry (vertex buffers) on the GPU. Maybe newer APIs like DirectX10 or 11 would support this dynamic tesselation approach in hardware.
I added two nVidia GTX 260 and one nVidia GT 240 card to Einstein @ Home , and voila this morning's stats show:

For a BOINC novice it can be quite daunting to figure out how to make it use all GPUs and not accept any CPU-only work units. Editing some XML files in some data directory isn't exactly user friendly.
If I send a video stream as a sequence of UDP or RTP packets, clumping together to perform some kind of forward error correction is perfectly possible and reasonable.
When you invent some kind of solution to prevent packet loss on wireless links, it should apply to all kinds of IP traffic and not single one protocol.
This is why I think this will not catch on easily. You can't just put a new router with their coding functionality into your home and expect this to work. It also needs support from the server hosting the content you want to acces.
The way they designed their system is end to end. Meaning that the internet server has to run a modified TCP stack and the client system (alternatively your router inbetween) also has to understand this modified TCP dialect.
The chance of millions of Internet servers changing to a (likely) patented, proprietary version of TCP is ZERO.
My wife has no problems buying black eggs of any kind in asia stores in Germany. Oh, and black eggs can be mailed long distance, it's fermented and thereby preserved food.
And you really can't conclude from the menu of a chinese restaurant what's going or not going on behind the scenes. I call bullshit on this one. No corporate espionage ring would need to use a "safe house" or "safe restaurant" for that matter to drop off secret information or to secretly meet. It's the information age, dummies!

The requirement to run an entire OS installation routine for a minor upgrade is ridiculous.
They should have handled this more like service packs.

But wouldn't the guys from 30 years ago eventually notice that you're trying to pay with newer currency, minted or printed during the last 30 years?
I guess I got to read that story now.

Hi,

The customer pays Verizon to offer a communication service, not a data retention and wiretap service. Thanks.
Look at what they did with Android. Seemed like a crazy project at first, but now they're essentially owning the market for mobile operating systems.
So let them do their unfocused things, because some of them will pay out big later.
Bitcoin is now dominated by FPGA and ASIC miners (dedicated hardware), most GPU farms have moved on to litecoin.
some of them might actually get the funding ;)
I heard Boeing has some batteries that meet these requirements.

And in case you want to read about the changes they made to TCP, here's the paper:
http://arxiv.org/pdf/0809.5022.pdf
The paper mentioned in the summary only does a performance evaluation for this TCP
dialect, but is light on details.

This is why this idea will fail.
