I've always wondered the benefits of long distance remote controlled operations. Wouldn't you much rather have a skilled surgeon standing over you performing with all of his/her senses, instead of some doctor in London?
Uh, I don't know if you guys realize, but that's just a direct copy and paste from the article. The site isn't loading very well, so I grabbed what I could and put it up here.
We've just released a practically silent Neuros LINK v1.2 (codenamed "Phantom") and figured some of you would be interested in the process.
Of course, there are easier ways to create a silent computer, the easiest being a net-top solution, with an Atom processor or the like. We've decided not to go that route with the LINK simply because we didn't want to make the sacrifice on CPU horsepower. Sadly, as we all know, there are still plenty of web apps and inefficient video streams that require CPU cycles. Instead, we architected a full power PC to be silent (or silent to an excellent approximation anyway) Click more to see what it took, or if you just want to buy, go here: we're good with that too.
1. Low power components: (45W CPU, no optical drive or HDD, nothing extra) less power means less heat generated in the first place, thus less for fans to need to remove. Although its a 2.7GHz CPU, the Sempron 140 still only consumes 45W, so we felt that was a nice tradeoff between performance and a manageable amount of heat.
2. Better Fans: We employed large, expensive, 120mm fluid dynamic bearing fans that are about as quiet as computer fans get. In fact they are pretty much silent save for the air they move.
3. vibration dampening neoprene mounts dampen any vibration before it causes noise. Vibrating sheet metal is a great source of very annoying noise and strategically placed vibration dampeners are very important.
4. Intelligent Fan control: We implemented the PWM (pulse width modulation) scheme to control fan speed throughout the system so that the fans would spin down (in a coordinated way) under normal use and only spin up when needed under heavy load (or in a closed cabinet where airflow is limited).
5. Elimination of most moving parts in addition to reducing power (and heat), the elimination of optical drives and harddrives means the elimination of the noise they generate. The flash drive used on the LINK is obviously silent (certainly to the unaided ear anyway)
6. Intelligent fluid dynamics of the entire system. One of the obvious benefits of controlling the whole system is that we have access to architect all the assembled parts when together, not just individual pieces. Thus we were able to replace the 70mm CPU fan with a larger, quieter 120mm fan that generates enough excess airflow that it can be used, in conjunction with a well placed power supply fan, to draw air to cool the north and south bridge chipsets of the motherboard well. If you open the case of the LINK, you'll find the components form a carefully developed airflow channel that covers the CPU, GPU, memory and power supply. Although the power supply is capable of running passively without a fan at all (it only operates at maximum ~40% of capacity in the LINK) we placed another fluid dynamic bearing fan to draw air into the power supply because it aided in creating the airflow channel needed. It also gives more headroom in case you do want to expand the LINK.
Although not obvious at first glance, there are a host of important details that were necessary to reduce noise levels to the level you'll find in the LINK. As one example, open the LINK case and you may notice there are standoffs that separate the main fan from the case by 10.5mm This distance was arrived at through careful research and testing. Place the fan too close to the case vents and turbulence is created that generates audible noise, too close to the heat sink or other components and you disrupt the airflow channel and not only generate noise, but also adversely affect the cooling.
So how quiet is the Phantom? 20 dB or less typically, but if that means nothing to you, put a different way, sitting on the couch 6 feet away, its probably less

It was an IBM exhibit. He meant one year old.
Anybody can practice whatever they want, as long as they don't try to kill me in the process. But these radical Muslims have been doing just that.
So... forever?
After the firings, every Activision-produced Call of Duty title will be destitute.

Sorry, that's the 2009 bill. The 2010 version -- the one relevant now -- is here: http://www.opencongress.org/bill/111-h1258/show

...because no one else will.
I think that all the time at the park!

I'm glad the defense chose people aware of the DMCA.
Forgive my oversight! May I recommend an alternative, such as http://thepiratebay.org/torrent/4602106/Abel_Raises_Cain?
We may never know.
Alan Abel is a huge media prankster, whom ran several famous hoaxes that tricked the media. There's a documentary on him: http://www.hulu.com/watch/56337/abel-raises-cain
