Although the U.S. pharmaceutical industry claims to fund roughly 43 percent of the country's research, that figure is misleading. The Office of Technology Assessment found in 1993 that two-thirds of research goes to "copycat" drugs---drugs designed to replicate the effect of a drug patented by another company. And according to the U.S. Senate Committee on Aging, "many of the dollars drug manufacturers claim are spent on research are actually spent on marketing research."

Building a Dead Silent PC

There's one more aspect to that. When you have very thin, long fins, like the Zalman heatsinks do, the thermal conductivity is too low for the heat to be transfered all the way to the tips. From what I can see on the photos, these heatsinks are not as efficient as they could be. IMHO the optimal heatsink would have a tree-like structure, whith thick 'stems' conducting the heat to many thin, but reasonably short 'leaves'. The Arkua coolers seem to somewhat follow this approach.
Semiconductors aren't that sensitive to moderate heat, in the way that it would destroy them; if they get too hot, you will just have system crashes, random resets, etc. (as if that isn't bad enough).
No, but heat kills bearings. So, the hard drive will probably be the first component to fail, especially with today's sensitive drives.
Another mid-term problem would be the electrolytic caps. They will dry up over time, which will introduce sporadic instability/reboots at first, and you'll be driven mad searching for the cause. Almost impossible to detect without special equipment, i.e. an ESR meter.
So, if you want a silent PC, you'd be better off buying cool components in the first place. It's just too much of a hassle (and expensive) trying to silently and reliably cool high power CPUs and graphics cards.
Actually, I own a SV1204H, I'm very satisfied with it, it is super quiet (read: inaudible), and it's quite fast for a 5400 RPM drive. I bought it on the basis of this review and the comments on the StorageReview.com boards.
I fail to see your point. You received 20 Samsung drives, the origin of which you don't know anything, and 100% of them failed, so all Samsung drives must be crap? Have you ever thought of shipping damage? And the fact that you obtained them fraudulently doesn't exactly increase your credibility.
From what I've heard, Samsung drives are the most reliable ones around (.01% RMA rate, I've been told). They also don't seem to plan to reduce their warranty, which is currently three years.
I'm not so sure... I mean you put a turbine on the train to generate electricity, and then drive an electric motor. Why not put a big turbine on the ground and distribute the electricity via a power grid? This would make the trains lighter, allowing for more passengers and saving energy, and furthermore, one big turbine has a much better efficiency than 20 small turbines. Hell, you could even have a nuclear power plant power the rail lines and have no pollution at all! Yeah, yeah, I know, you lack the infrastructure... it would be a good use for your money though, instead of spending ungodly amounts for your behemoth military machine. Whaddaya say, one aircraft carrier less, and get a state of the art nationwide railway grid for that?
Red dots appearing out of nowhere can also spook people into thinking that they're being targeted with a laser gun sight. And if you're a police officer (or the Maryland-DC area with the recent plague of random sniper attacks) that might not be an entirely unreasonable fear.
Sorry, but that's just dumb (I mean using a visible laser as a gunsight). It's been shown in movies, probably because it looks cool or whatever, but if you want to shoot someone, you don't want to be seen, and you don't want to give them an advance warning. And a beam of red light pointing to your location is detrimental to that (granted, depends on atmospheric conditions, but lasers can be seen pretty well most of the time, especially in dark environments). Laser sights have originally been designed for short range, close quarter combat, where you have to aim quickly, but they are completely obsolete by now, and the advantage over traditional iron sights was dubious at best in the first place. For CQB, holographic sights are commonly used, and snipers still prefer the good ole' scope.
The problem is, how do you secure a network that is managed by software? There are going to be errors in the network administration software, and people are going to find these errors and exploit them.
An admin can react to an attack intelligently (OK, depends on the admin) and take appropriate counter measures. But a program's response will be predictable. And so far, in games with many complex variables, humans have always won against computers.:)
Yes, specialists are expensive, but getting your whole network 0wned by 12-year old script kiddies will be more expensive in the long run.
Because the robot won't fit through this one inch hole. For the next try, they should build a robot that is able to drill a hole big enough for itself to move through.
The moon's diameter is 3476 km. The circumference therefore is 3476 x Pi = 10920 km. One moon day lasts 28 earth days, therefore the prison would have to travel 10920 km in 28 earth days to stay in the night part, which equals 390 km in one earth day or about 16 km/h, which is hardly feasible for any vehicle given the rocky mountainous terrain.
If you had read and understood both the article and my post, you would have realized that we are talking about using X on resource constrained devices, i.e. PDAs. Those have commonly not more than 32 MB of RAM. They also don't have a harddisk, and their CPU power is maybe comparable to a slow Pentium, and that's for the high-end models.
Obviously, your response (and those of several others) to my post was a knee-jerk reaction at criticism towards X. I am merely saying that X is not particularly suited to this special kind of application. I myself am using X/KDE on my main PC. But you guys need to realize that X is not necessarily the best way to implement a GUI on everything that has a CPU and a display.
X is a resource hog. There are more efficient ways to implement a GUI, like using the framebuffer device, or Qt/embedded. X has its advantages when used on networks, like the client/server model, but it's overkill for personal devices. You don't run Oracle on your handheld to store your phone numbers either. Or do you maybe want to connect an X Terminal to your PDA?
Wait, maybe that would be cool, hmmm, you could then use all your PDA apps on the big screen while you're at home.
The applet was implemented using only 2-body methods, and hence should not be used for determining accurate long-term trajectories (over several years or decades) or planetary encounter circumstances.

So it does only take into Account the Sun's and the Asteroid's Gravity for the Simulation.
Guess it's time to look for a nice House in Iceland... that geothermal Energy there will sure come in handy during global Winter.
The sun blinding is a non-issue (the sun would have to shine directly into the mirror), as there is no atmosphere on the moon. Using a typical slotted dome, you can make observations 24/7.
While you're at it, also build a radio telescope. If set on the far side of the moon, it would be shielded from the enormous man-made interference that makes radio astronomy very difficult today.
Last, but not least, building a permanent base (even if unmanned) on the moon would give us valuable knowledge and experience, which would be useful with regard to a mars mission.
The chicken-feather microchip is not as weird as it sounds. A microchip is basically a wafer of silicon inscribed with a dense maze of transistors. For the chip to do its computational magic, electric signals have to travel across these transistors.
These signals travel faster in the presence of some materials than others. Air, for instance, allows the fastest movement of all, because it provides essentially no resistance. When traveling near solids, however, the movement tends to kick up opposing positive charges. These charges can distract the signal from completing its appointed rounds.
So what are they saying? Air offers no electrical resistance? Last I heard, air was one of the best insulators around. Or did they perchance confuse resistance with the dielectric value?

A FW190D could shoot the crap out of this little bugger.
But it's only a demonstrator anyway. The final version will probably have weapons.
Or maybe someone just tossed a violin over your freakin' house.

You have a two year dealer warranty in the EU, mandated by law.

Sounds like an urban legend to me. The Amiga had a "Trashcan" (that was its actual name) since it was introduced (AFAIK 1985).
The problem is, how do you secure a network that is managed by software? There are going to be errors in the network administration software, and people are going to find these errors and exploit them.

Well, they are obvioulsy not the brightest.

Yes, and by that time you will all be speaking Spanish.
I'd really like to see that ... I'm curious as to what kind of axe is used.
