who reads TFA? i was describing how my own PC achieves the same goals described in the summary.
i hate people who say they hate things and generalize. my clue is huge and raging.
i'm afraid that they use the term "technology" because they plan on suing you if you don't pay them to license it. a computer that boots quickly from the BIOS to a thin OS and runs Windows in a remotely accessible VM is not new technology in that sense.
you can't just append "...that doesn't suck" to existing product descriptions and patent it.
I think they keep putting it on slashdot each time OCZ changes the expected shipping date. I ordered one of these a month ago expecting shipment on 7/1, but the shipping ETA keeps changing (looks like 8/1/08 now).
who knows, maybe they'll find a cure for my uncle's ALS before we actually get to try this on him... this thing costs about 1/100 of the price of the eye-ball tracking system, and i bet it will be much, much faster for simple mouse control.
i always thought cloud computing is what happens when a bunch of researchers score really good pot.
"i bet we can get more funding if we call it a paradigm shift"
once you get out of LEO you're not going to fair very well in the van Allen radiation without someone serious design modification.
this article is so stupid... perfect for a slashdot debate.
you better order one now before an Apple-filed injunction is approved... not only will you get a cheap & better mac clone, you'll also give them the cash they need for their legal fun.
better act fast!
I'm currently using Magneto-RAM in a project.
I'm also interested in the development of Carbon Nanotube-based NRAM from Nantero.
Density is more important than speed for most NV storage applications. Unless the cost structure and density changes substantially vs Flash ROM, these types of exotic NV RAMs are going to be useful only in situations that require a lot of write accesses: like storing the directory info for a cheaper/larger Flash-ROM array which can't support as many write cycles.
Even in these situations the exotic NV RAMs are just a replacement for SRAM and a Battery which is cheaper because the structure, processes and materials are standard.
From TFA "Heise also claims that the cores will feature a 512-bit wide SIMD (single input, multiple data) vector processing unit. The site calculates that 32 such cores at 2GHz could make for a massive total of 2TFLOPS of processing power."
I don't see how they get to 2 TFLops.
512-bit = 64 bit * 8 way SIMD or 32 bit * 16 way SIMD. Let's go with the bigger of these two and say we are performing 16 single Floating point operations per clock-cycle per core. 16 operations per clock-core * 32 cores * 2 Billion clocks per second = 1024 Single Precision GFlops. It looks more like 512 Double Precision GFlops for 300 Watts which means a DP Teraflop on Larabee will cost you 513 Dollars a Year at 10 cents/kWH. If we're considering single precision, we can cut this in half to 257 dollars per years per single precision teraflop.
Compare to Clearspeed which offers 66 DP GFLops at 25 Watts costing 332 dollars for a sustained DP teraflop for a year.
even the NVidia Tesla has better performance at single precision: you can buy 4 SP TFlops consuming only 700W or 5.7 GFLops/Watt, for an annual power budget of 153 dollars.
Browsers need a mechanism for connecting two clients' browsers without going through an server. This would greatly ease chat clients and possibly even browser based file-sharing applications.
This feature requires the same sort of access controls that would make cross-site scripting secure. Such policies would make it a lot easier to make mash-ups that access remote machines directly instead of through an arbiter. Eliminating the one-client-one-server communication bottleneck currently built-in to JavaScript would decrease the network traffic generated by some applications by more than 50%.
one day we will allow UAVs to autonomously attack hostiles after they make a positive identification.
in the lingo of recognition systems, the extermination of humanity would be considered a Type I error.
I really hope that same type of open-source economic irrationality will help fund my open-source FPGA tools startup!
my point is that there are a dirth of FPGA boards with better cost/performance value that could be used to prototype a graphics rendering FPGA system. Physical hardware isn't the limiting factor to an open source graphics card; the open source FPGA 3-D rendering code is the real missing piece. In fact, making a board was probably a distraction for this project because by the time the firmware is ready for real graphics workloads the FPGA on-board will be obsolete.
you might be getting ripped off if you're paying $1500 for a Spartan-3 board.
I guess they don't really have the board volume to get low prices. But If you want a graphics card for $1500 that's probably less functional than an NVidia commodity card, I'm not gonna stop you.
OTOH, If you're interested in FPGA programming and a novice at it, you'll want to get a MUCH MUCH MUCH cheaper Spartan board (like 50 to 150). See http://digilentinc.com/ for good starter boards.
If you're serious about FPGA programming (or just willing to pay $1500 to $3000) you will definitely want to get a board with a Virtex or Stratix on board: http://www.xilinx.com/products/devkits/HW-V5-ML501-UNI-G.htm
FPGA programming environments still mostly suck. it's a market impeded by proprietary standards and a whole lot of NP-Hard algorithms. We're working on it...
The observer effect: the more energy we consume studying the effect of energy consumption on climate change, the more we'll have to incorporate this factor into our models.
Positive feedback: if the results of these studies are striking enough to merit funding for more research, we'll no doubt consume even more energy to determine the effects of energy consumption on climate change.
Self-fulfilling prophecy: if this positive feedback between funding for climate change research and supercomputing energy consumption is not counteracted by efforts to reduce supercomputing power consumption for climate change research then we're damning ourselves by studying it.
this article makes you wonder, where would GNU be without RMS's beard?

Samson would have written one helluva programming language...
there are some serious problems in parallel computing the greatest of which is teaching people how to write good parallel programs. this isn't like building social networks or applications on top of social networks--that really is the latest-latest fad.
anyone seeking to get-rich-quick off parallel computing aught to reconsider their field of choice. it's more like get-frustrated-quick scheme.
what's scary about this article is the fact that links like this propagate by botnet spam.
earlier this week we were reading about botnets engaging in spam attacks on phpBB sites. after reading that I checked up on some old phpBB and mediawiki sites that I created but never used. they had become infested with pictures and links to porn sites with tags like pedo kiddie lolita etc. based on the volume of material and pattern of posts, this was obviously done by a spamming botnet designed to propagate these links.
is it possible that this is related to the FBI sting? i wouldn't put it past them to actually engineer this sort of operation, or for some hacker to include one of the FBI's links in their spam-bot's list. many of the classmates i knew who did these kinds of hacks were the same kind ending up at the NSA or various other government TLAs... or Google.
A patented voting machine? I find it hard to believe Sequoia is responsible for any of the major advances in electronic counters of the past 60 years. What's the title of the patent:
"Method and Apparatus for Hijacking Democracy"
and they would have gotten away with it, if it wasn't for you meddling slashdotters...

i think vision recognition and hand tracking have the most potential for musical control. try hooking up HandVu or CamSpace to Max/MSP for example.

MRAMs come in 4 MBit density so it replaces battery backed 512 KB SRAM chips.

Here's some examples of 3-D engines for FPGA from the 6.111 lab at MIT:
3-D Pong (using rasterization):

Ray Tracing:
http://web.mit.edu/6.111/www/s2007/PROJECTS/5/main.html
There are hundreds of videos and code for FPGA projects up at http://web.mit.edu/6.111 (see project appendices for code).
Use a $150 Spartan 3E Starter Board from http://digilentinc.com/
It has 4 channels of 12 bit DAC and 2 channels 13 bit ADC.
If you want 24 bit I/O you can just by the cheapest board avaiable and solder on CODEC (AC97 is 18 bit, Analog Devices makes 24 bit ones)
you might be getting ripped off if you're paying $1500 for a Spartan-3 board.
I guess they don't really have the board volume to get low prices. But If you want a graphics card for $1500 that's probably less functional than an NVidia commodity card, I'm not gonna stop you.

If you want to have it on PCIx:

You can also get FPGAs socketted for AMD's Hypertransport bus and Intel's FSB:
