...but I didn't see how this worm will deal with the fact that it has to infect a hetrogenous environment. There is no way a single variant of a worm could effect every internet connected machine out there. If there are different versions, then how would it update itself? It's not like a worm can just infect a random computer at will, there has to be a specific vunerability that it uses. The best defense to this kind of attact is the kind of internet we have now: different OS's on different hardware running different services.
I can't find it on the website anymore, but the author of Virtualdub had a good explanation why he didn't add VBR audio support. As I recall, it only works because most players do not strictly follow the AVI specification.
Mailing someone is (roughly) the same as emailing them. Companies have to pay to mail something to me, why shouldn't they pay to email something to me?
They do pay. They pay their ISP to carry their traffic, just like you pay the post office to deliver your letter.
Telemarketers have to pay for all of the many phone lines they use to call me and 1000 other people in a 12 hour period. Spammers only need to borrow one computer for 10 seconds to spam a million people.
I think the telemarketer is the correct analogy for this situation. Just like a telemarketer pays the telephone to contact you, the spammer pays their ISP to email you. The only difference is that it is quicker and more efficient with computers.
He's not talking about limiting speech, just making them pay for their usage of the hardware medium they choose. They can come to my door for free and speak all they want. They shouldn't, however, be able to use the computer resources _I_ pay for to bother me.
As I have stated above, spammers do pay (their ISP, not the recipient) for their usage of the hardware medium. You keep saying that spammers should pay, but you don't specify who thay should pay. Do you mean that they should pay the recipients of their emails? Telemarketers also use your resources without prior permission, so should you be able to charge them for calling you?
You have to start from a pre-existing distribution. To solve this problem, some LFS users have made bootable CD's containg a complete LFS system which can be used as a base to compile from.
The best way to learn and use Linux is to grab a root/boot diskset and hand-craft your partitions, disk structure, and compile everything.
There is a book called Linux From Scratch that gives instructions for building a complete linux system from source code. The instructions are good enough that you don't have to be an expert to follow them. I would highly recommend this "distribution" to anyone wanting a completely customized linux system.
If the nitrogen is kept at the right pressure, then it doesn't even have to be kept cold
Yes, but this would be useless for superconducting applications. The whole point is for it to be cold, or else the superconductor won't work.

Fission in a Box
·
· Score: 1
I wouldn't worry about meltdowns, though. Firstly, all reactors built within the past two or three decades have doubly- or triply-redundant systems that shut them down when they overheat. Secondly, anything that uses water (heavy or light) as a moderator *can't* melt down. Without a moderator, the reactor stops dead (it needs the moderator to react). With water as a moderator, your moderator disappears as soon as it heats up enough to burst pipes. End of reaction.
Close, but not quite.
You are correct that the nuclear reaction stops when the moderator is lost, but fission is not the only source of heat in a reactor.
A signifigant fraction of the heat generated is from the radioactive decay of fission products. For many reactor designs, this decay heat is enough to raise the fuel temperatures to damaging levels if it is not removed.
Decay heat is what caused half of the Three Mile Island core to end up as a puddle on the bottom of the pressure vessel.
All this depends on the materials used in the construction of the fuel elements and the size of the core. A smaller core will have larger heat losses with normal cooling removed. I believe that there are suitable materials now that can withstand high enough temperatures to make decay heat removal not an concern, but This is not the case for most reactors currently in service.
Lastly, the "slowpoke" style of reactor described can't have runaway heating at all. As it heats up, the core expands, pushing the fuel rods away from each other and making the reactor less efficient. Do whatever you like to it; it doesn't run away.
It sounds like you are describing a negative temperature coefficient of reactivity ("negative void coefficient" if you are a civilian). In a water-moderated reactor, an increase in temperature will reduce moderator density therefore cause a tendency for power to decrease. This provides for negative feedback and causes reactor power to change to match the heat removed from the system without operator intervention. This does not prevent an over power condition - it just means that the reactor is inherently stable.

Because it's fashionable to bash religion for several reasons.
The majority on people in the US probably still believe in god to some extent. It's always fun to feel intellectually superior by bashing the (mentally inferior) majority. You see this in a lot of areas (microsoft bashing being good example)
As with most any arbitrary group of people, a non-insignifigant percentage of religous people are idiots and are also very vocal. It's easy to think of all the stupid things done by people in the name or defense of religon and assume that anyone who believes in the existance of god is also an idiot.
I also submit that a good number of people also feel as you do, but don't bother to speak up. It is much easier to say nothing and keep browsing rather than defend an unpopular position.

It depends on the site and what client I'm using. I do most of my web browsing from windows and many of the FTP clients have default email addresses they use for passswords. For example, i think Getright uses "getright@getright.com" or something like that.

If people really wanted this to stop, all they would have to do is not divulge any personal information at all.

There is an old article on PHPBuilder.com that describes a meathod for creating dynamic, indexable pages. The article is written for PHP, but you should be able to use the same technique with other languages. Even if it doesn't work for all your pages, it still is a useful technique.
