With just one bucketfull of martian soil, one can power the energy needs of the entire planet for a year! All that is necessary is to combine it with a bucketfull of anti-matter in a sustained and controllable manner.
Of course, if an anti-matter based reactor existed, we could just get dirt from the Earth. But then, if cold fusion existed, it would hardly be necessary to go to the Moon to get fuel.

Nuclear _power_ plants in the United States have never killed anyone.
Weapons production, that is a different story. The contaminates that have seeped into the Columbia River were mostly the result of the plutonium separation process, which stopped in 1972. The Washington Public Power Supply system reactors on the Hanford site have never been the cause of contamination.
No, I mean steam explosion. They removed too many control rods for a test, which allowed the reactor to got so hot that it the water surrounding it turned to steam and exploded. Since there was no containment vessel, the explosion threw fuel everywhere and made a big radioactive mess. Check this page http://www.uilondon.org/cherntim.htm to see a breakdown of the events. The explosion is described at the very end.
You might want to rethink that brick house. You will actually get more of a dose from a brick house than a wood house, since the bricks themselves release radiation.
Hanford is not in western Washington, it is in eastern Washington. None of the reactors there (or in any western country for that matter) are anything like the one in Chernobyl. For one thing, they all have containment building around the reactor core, so if a steam explosion like Chernobyl were to happen, it would be contained and there would be no release of radioactive material. The fact is, in the United States, more people are killed every day by the pollutants of fossil fuel power plants than have ever been killed by nuclear power plants in the US (that being zero).
There have been no less than two PhD dissertations based on writing a Netrek robot. The netrek server newbie.psychosis.net has bunch of robots that keep game at a full 16 players. When a human comes in, one of the bots leaves. They are in "suck mode", so they fight much more poorly than they could, to give new players a chance to kill them.
I know of no dubbed or subtitled version of the series, other than maybe a fan sub. There are subtitled versions of the various movies out.
As to the editing, I've never seen the original, but I did read a web page by someone who watched both and listed the differences in some detail.
There wasn't much really, a lot got through that probably won't be in the Gundam Wing dubbing being done now.
The intro WWII video footage of American dive bombers destroying the Yamato was cut. A bit of fan service with Nova (her name is Yuri?). The doctor is always drinking "spring water". And a few bits of violence, like when Derek Wildstar (Kodai?) tries to kill the captured Gamilon.
Go look at the student pictures for the University of Washington school of library and information science here, then take a look at the list of grad students in the computer science and engineering department. From the first 30 students listed, it looks like the ischool has 23 women and 7 men. The CSE department has 25 men and 5 women. Why is the first nothing unusual but the second a terrible problem that needs to be corrected?
I suppose the true reason there are more men and women is some fields is that the ratio of men to women in the general population is close to 50/50. Since some fields have more women than men, other fields must have more men and women for it to average out. What the center for women and technology (I hate hypocritical organizations like this who preach about equlaity but have sexist name like center for women and the implied and not men) needs to do is convince women that computer science is better than information science, or actively discourage women from entering fields like education or psychology where they are a majority. Or they could try to get more men to enter fields that have more women in them.
While it's true that a saturated ethernet will slow down and become less efficient, this isn't a problem for most beowulf clusters. Most smaller clusters that use ethernet have it all setup with a switch. The switch has an aggregate bandwidth much greater than that of normal fast ethernet, and uses store&forward, backpressure, and flow control to keep the network working. The result is that you don't see the collisions that make un-switched ethernet slow down. For instance, this is from an interface our beowulf cluster, which has a switch.
RX packets:12889863 errors:0 dropped:0 overruns:0 frame:0 TX packets:13388470 errors:2 dropped:0 overruns:2 carrier:0 collisions:0 txqueuelen:100 Notice how after 13 million packets, there are none collisions. Next, here is an unswitched interface on a firewall machine.

From what I've read, their code doesn't need a lot of interprocess communication, so they can get by with just one or two ethernet channels.
I just got some new drives at work, and want to share the benchmark to enlighten the world about the ever important and exciting SCSI vs IDE holy war. Well.... maybe I just want to brag, so shoot me.
Here's the bonnie results for the system. The drives are two IBM ultrastar 18LZX drives, 18GB, 10k RPM, about $580. The controller is the onboard adaptec U2W on a supermicro P6DBU. They are setup with a raid0 partition using the new raid 0.9 code, with kernel 2.2.13ac2. -------Sequential Output-------- ---Sequential Input-- --Random-- -Per Char- --Block--- -Rewrite-- -Per Char- --Block--- --Seeks--- __MB K/sec %CPU K/sec %CPU K/sec %CPU K/sec %CPU K/sec %CPU/sec %CPU 1024 10695 99.6 60193 53.8 21373 42.9 11092 95.4 50926 29.6 508.3 3.8

"Person most deserving $2000" What kind of award is that? Better to call it best ballot stuffer. Unsung hero? If no one knows about someone's work, who is going to know to vote for them?
I always hated school sponsored popularity contests, where all the jocks and cheerleaders get to give themselves awards and see who had the most friends. Is this really all that different? Doing stuff like this creates resent among all those who feel left out. Especially since most open source work is a group effort, to single one person out is a slap in the face to all those whose work is ignored.
I suppose none of this matters, since we already know who will get all these awards, Linus Torvalds, Alan Cox, Larry Wall, Apache, XFree86, etc.
What's going to happen on Jan 1st? An accidental nuclear holocaust? Terrorists blowing up the space needle? Looters killing you for the jugs of water you're hoarding? Planes falling out of the sky? The dead rising from their graves to wreck the wrath of a vengeful god upon the earth? Not bloody likely. When the new year's parties are over, and most people no worse off than a hangover, what Y2K related event will have killed the most people? Most probably drunk drivers. Funny you don't see anyone worrying about that, even though it's a much more real danger than anything an AK47 can fend off.
Since no one seems to really know netrek's anti-borg system works, I'll put it down in detail.
When a new client binary is created, the person compiling it makes a public/secret RSA key pair. The public key is sent to the keyserver (Carlos V), while the secret key is compiled into the client. The code to create these keys, as well as the client/server (they are the same) routines to do RSA aren't in the client or server source. This is because of export restrictions. Anyone can download the RSA source from a certain FTP server in Europe, which is what I did when I released my netrek client. The RSA source isn't widely distributed, but there isn't anything closed about it. The only thing secret is the secret key, which only the person compiling the client knows.
After the client connects to the server, the server sends a cookie of random data to the client. The client sticks the IP address of the _server_ (via getpeername()) in front of the cookie, and encrypts it with the secret RSA key inside the client. The server gets the response, and if it decrypts properly with the client's public key, the client is allowed.
There are several weak points to this method. The most obvious, but not the easiest, is to somehow extract the secret key from the client. This was how DVD was cracked, by extracting a secret key from the Xing player. The secret key isn't actually in the client as raw data, rather C code is generated that performs the operations needed to do the RSA encryption with the key. With the C code in front of me, it's not trivial to tell what the key is, figuring it out from the compiled code would be very difficult indeed.
Another weak point is binary hacks. The client does NOT perform a binary hash (checksum, CRC, md5, etc.) of any kind, so you can take a hex editor to it at will. There really is no way to stop this; if you put in a checksum, someone can just hack the checksum code. With the complexity of programs like netrek and quake, adding new features with a hex editor is a difficult task. Not as easy as fiddling a few bytes on console systems with a game genie or the like. Netrek does all game mechanics in the server, so "no damage", "infinite ammo", "shoot through walls", cheats just aren't possible.
The easiest way to get around this system is a man in the middle attack. You have a real client connect to server via your cheat proxy. The proxy understands the game protocol, and can cheat in a number of ways. For instance, it could allow the normal client to connect to the server and authenticate isself, then pass control over to a fake client. Netrek trys to make this hard by putting the IP address of the server inside the cookie. If the real client thinks the server is at 127.0.0.1 put the server is really at 1.2.3.4, the RSA response will be bad. You can get around this with a dynamic library hack to getpeername() or a kernel level hack for static binaries. Or have a tranparent proxy that can intercept packets.

Think about how film distribution works now. A photo lab has to produce a new film for each screen that the movie is to be shown on. If a multiplex is showing the movie on two screens, they need to flims. These come on about 7 or 8 reels in one or more large canisters. When the theater gets them, they have to be spliced together onto a large platter. This takes much longer and is more labor intensive than copying a tape onto a harddisk. When all the film is on the platter, it weights upwards of 100 pounds and isn't something a person can move alone. Think about the difficulty of distributing all this film to every theater vs a few tapes. Think about the cost of all this film, vs the cost of tapes.
Think about it. The distributor fedexs a DLT tape to the theater, who then copies it on their RAID before the show. Just like they have to do now when they put the reels onto a single platter, except copying a tape is faster and easier. Ebert seemed to think that a new $75,000 RAID array neeed to be trucked to the theater for each new show.
I remember when a 64MB hard disk was huge. Now most home computers come with that much or more ram. Compared to what existed 10 years ago, we do have RAM mass storage.
It can project film at 48 frames per second, twice the existing 24-fps rate.
NTSC does 60 fields per second when it's the evening news or a soap you're watching. Doesn't make much of a difference, does it?
MV48 uses a new system to pull the film past the projector bulb without any jitter or bounce.
Electronic systems don't jitter or bounce either. They also don't have scratches or dust, unlike film.
The source of their signal is an array of 20 prerecorded 18-gigabyte hard drives, trucked to each theater. This array costs an additional $75,000, apart from the cost of trucking and installation.
$75,000 for a twenty disk raid array? That's pretty damn expensive. And has he never heard of tape? A new movie could fit on a couple of 70GB DLT tapes, no need to "truck" a new RAID array in.
Imagine sometime in the future when the interworkings of genes in understood to the extent that semiconductors are understood today. 3rd year college students would take courses in Basic Genetic programming, and have to create a simple bacteria as a final project. Genetic programmers would create custom organisms like layout engineers make custom ASICs now. You could have standard series of basic components, like an 74HC11 quad Krebs-cycle module, or a LM317 metabolism regulator with 100kcal/day max rate and 85% effiecency.
I wonder if the genetic scientists of the next decade will be thought of like the pioneers of VLSI back in the 60s are thought of today.
There are two versions of the DUNE movie. Well, really there are more, but just two important ones. There is a "short" one, like 2 and half hours, which was shown in theaters and is out on tape, and it credits David Lynch as director. There is a 3 hour version, which came out on TV and was reshown by the sci-fi channel recently, that has David Lynch's name removed and credits Alan Smithee.
Several years before the David Lynch Dune, there was a plan to make a Dune movie. This is the one that had HR Giger and Salvador Dali for artwork and Pink Floyd for music. After Jodorowsky spent several million and had nothing to show for it, Hollywood canned it.
