This embedded system contains: 1. Three Ethernet controllers. 2. VGA contoller. 3. Two RS-232 controllers. 4. Flash drive. 5. PCI bus. 6. WiFi card. And it starts booting Linux kernel in less than a second after power on.
I don't see why my notebook should take about 8 seconds JUST TO START BOOTING THE KERNEL.
Current HD players are too brain-damaged, so it's not a good comparison.
Nah, it's not worth it. Turning off last access time (BTW, it's turned off by default in Vista:) ) cuts my C++ project building time by 30%. I don't think any kind of intelligent defragmentation will be better.
Actually, I think that it will be possible in near future to create environment to 'bootstrap' protein synthesis from DNA without a living cell. That way we'll be able to truly create a new life from scratch.
Actually, there's some work on artificial ribosomes. So it may happen even faster I think...
You just need to have a common ground for all your devices (speakers, amplifiers, etc.). That's even easier to do if your house is not properly grounded.
You don't even need oxygen free copper. Normal copper is quite enough, even aluminum is quite enough.
The only thing you need is some shielding to protect cable from RFI (it's real and measurable - try to put your cell phone next to speakers). But again, nothing fancy - a common shielded coaxial cable is OK.
Wow, I am now left wondering why they waited so long. (The absence of competition, perhaps.) Have you missed the part about using computer modeling (it was used to solve a system of differential equations describing stability of boosters)?:)
Russia was developing rocket technology even before capturing Penemunde. GIRD (http://en.wikipedia.org/wiki/Jet_Propulsion_Research_Institute) worked since early 20-s. As a result, for example, http://en.wikipedia.org/wiki/Katyusha rocket launchers were used extensively during the WWII.
USA had a lot research in rocketry too or else German scientists couldn't have done that much all by themselves.
I watched it. It contains A LOT of factual errors.
Better read Chertok's memoirs (http://www.astronautix.com/articles/chemoirs.htm) and his book "Rockets and people" (unfortunately, I can't find its translation in Internet, but I know it exists) if you want to know about Russian space program.
Actually, a lot of Russian space technology was built on old technologies and as a result was quite reliable. For example, the R-7 rocket used to launch Sputnik used technologies from 20-s and there's a story that burning logs were used to ignite the first stage engines. But at the same time computer modeling (yes, even at that time!) was used to compute boosters parameters.
BTW, R-7 and its successors have become the most successful launch systems so far.
Water+ammonia chillers are not very efficient, and will require a lot more machinery. It will be probably more economic to use conventional AC.
I live in Russia, and we have I don't know how much hundreds of thousands kilometers of heating pipes (almost every house in Russia has centralized heating). And they have to be maintained regularly, believe me - it's not easy and cheap.
Oh, and Soviet army also defeated the largest continental part of Japanese army and was preparing for the invasion (actually, Russia DID invaded several Japanese islands).
Bullshit. We have enough U-238 to last for several centuries. Of course, you have to breed Plutonium from Uranium. And there's also Thorium - it can be bred into fissile material.
But even if we use U-235 and reprocess spent fuel - we'll have enough fuel for a looong time. Currently, only about 15% of U-235 is burned until it is poisoned by fissile products.
Deflation is actually BAD for economy (look at Japan) because it tends to reduce economic growth ("Why should I buy a new TV? I'd better wait unitl it costs less").
Most economists believe that a healthy 2-3% inflation is the optimum.

I work with embedded systems, and my MIPS-based 166MHz board boots Linux in about 5 seconds, kernel loading starts almost immediately after power on.
I always wanted to have the same capability for my notebook. Sigh...
The second one is called 'Tangents' by Greg Bear.
But if our space-time will flip to 4D, then it will be a sad future for the Earth. For one thing, there's no stable planetary orbits in 4D...
Actually, local domains are very popular at some countries. For example,.ru domain is very popular in Russia, .ua is very popular in Ukraine, etc.
It works on any Windows since Win2k.
You can also use fsutil utility to do the same thing: http://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/fsutil_behavior.mspx?mfr=true

Thanks for clarification!

It's even more amazing, that the first _automated_ spacecraft rendezvous was done without using a digital computer :)

What are you going to do with _additional_ heat during +40C heatwave? You know, that's when nuclear plants have problems with insufficient cooling.
Besides, you can't effectively transmit hot water for more than several kilometers. So this severely limits possibilities.

SpaceX capabilities are nowhere close to capabilities of Russian "Proton" rockets.
I very much want SpaceX to succeed, but it's doubtful they will be ready to deliver large cargo to ISS by 2010.
Eclipse has very little metadata in .project files. Essentially, it stores only paths and some project settings there.
.project files from POMs (Project Object Model files).
It's perfectly possible to use several IDEs in one team. For example, most of my team prefer IntelliJ IDEA, but some use Eclipse.
Also, you can use Maven (http://maven.apache.org/) and autogenerate Eclipse
Wi-fi equipment band partially intersects the HAM band, so it's possible and have been done several times.
Vendekapetz blisitsa!
