Actually, you can implement something like 'domain' prompt.
We use LDAP authentication as the primary login method but in case LDAP server is down there is a fallback to standard Unix/etc/shadow authentication. It's just a simple line "auth sufficient pam_unix.so nullok_secure" in PAM configuration.
Additionally, you can configure PAM to parse names like "SCB\Administrator" as "Administrator" in Samba domain "SCB". We use this for winbind authentication.
Actually, zoned pricing was widely used in Russia a few years ago. Most providers offred unlimited Russian traffic and expensive (about 10 cents per _megabyte_) international traffic.
Surprisingly, this worked well enough. Google/MSN/blogs/browsing required very little traffic (remember, that was before YouTube and Flickr) and nearly all major software archives had mirrors in Russia.
Curiously, this practice came to end when a few major providers in Russia terminated their peering agreements with other Russian providers and tried to charge a fee for their traffic (this was later dubbed "The Great Peering Wars" in RuNet). Minor providers were forced to use international channels and international Tier-1 providers (Telia, Sonera and C&W) had expanded their Russian channels as soon as possible. So international traffic prices fell from about $10 per gigabyte to about $2 per gigabyte in several months.
But USSR thought that USA (and other capitalistic countries) also had no rights to exist (because of oppression of working class). Of course, that doesn't mean that USSR wanted to kill everybody in the USA.
Actually, "we will bury you" means simply "we will outlive you" in Russian (yes, I'm a native Russian speaker).
It's also the case with Iran: a lot of threatening Iranian rethoric (like the promise to erase Israel from the world map) is just incorrectly translated arabic.
GNU/Hurd developers are commited to create THE best possible kernel. They don't have any time pressure so they can freely make experiments in the true spirit of Open Source.
Right now, there is an ongoing effort to use Coyotos ( http://coyotos.org/ ) to create the first operating system with the proved correctness of its kernel.
Besides, message-passing interfaces (the core feature of microkernels) can be potentially very efficiently implemented on multicore processors. For example, ARM Fast Address Space Switching (FASS) can potentially make microkernels FASTER than common monolythic ones.
Nope. H2+O2 reaction releases enough energy to make different nitrogen oxides. So you'll get nitric acid (from immediate reaction of oxides with water vapour), NOx'es and possible some other bad things (from reactions with dust particles).
Bacteriophages are VERY specialized. They can't penetrate into animal (or plant) cells because they are too large for it, and they can't use their injection system because animal cell walls are dense as bacterial cell walls.
Actually, bacteriophages (http://en.wikipedia.org/wiki/Phage) are the smallest syringes in nature, and they actually have proteins that store the energy needed for injection of genetic material through the cellular wall!
Phage therapy is a very real alternative to antibiotics. In fact it is already used with much success: my cousin was treated with phage therapy after a chemical burn complicated by kidney infection (strong antibiotics would have destroyed his kidneys).
Yes, I've learned that technique when I was in a hospital with 3rd degree burns on my leg (I was 10 years old at that time).
Doctor told me to think about my favorite movie heroes and try to imagine their adventures at the times I was given painkillers (I ended up thinking about programming). It worked, after some time I could do without painkillers most of times.
And it still works (I'm 23 years old now), it's particulary useful when I'm at the dentist's because oral anastetics don't work well for me (unusual nerve position, don't know how to say this in English).
Alkali metals do not explode with a great enough power, they just react very violently. But you can explode the resulting hydrogen (that's why lithium is the best choice).
RTGs were used in autonomous lighthouses and beacons in Russia. The core of a such RTG is a small cyllinder of radioactive material which is heated to 300-400C by radioactive decay.
There's only a small problem: you will get a fatal exposure after two or three minutes near such RTG.
You can put enough of explosives in extra battery pack or inside an extra HDD bay on multimedia notebooks.
Acetone peroxide is a high explosive (only about 15% less effective than TNT), you don't need more than 200 gramms to blow up an airplane's frame. And you don't need complex detonators to blow it - just pack it into a plastic cover and hit it hard with your fist.
And acetone peroxide is ridiculously easy to make. Some years ago I made about 20 grams of it at home (just for fun) without any problem.
Even better, you can make acetone peroxide from fairly household chemicals. And you can pack enough of it into notebook battery. Just imagine, you open notebook and the whole plane explodes.
I've always wondered why acetone peroxide was not used in airplane bombings. Now my thoughts are answered:)
Another cool method to explode airplanes may be by using alkali metals to produce hydrogen and make a volume explosion, 100-200 gramms of lithium will be quite enough to blow up an airplane. The best way to produce hydrogen is to dump metal chips into a bottle of 98% alcohol - lithium reacts with alcohol much slower than with water so hydrogen does not blow up immediately without reaching sufficient concentration.
It's fortunate that terrorists usually have no imagination.

Actually, UN is NOT a pure democracy because of veto-wielding countries.
The article means half-life of methane in atmosphere of the Mars.
Heatwaves?
Maybe becouse these rights are guaranteed by the Constitution?
Ok, fine.
So take them to a _regular_ criminal court. No evidence? Tough luck.
It's the only joke about lawyers. The rest are true stories.
Actually, density or supermassive black holes is _less_ than the density of air!
That's because the Schwartzshield (can't spell that in English) radius grows as the second degree of black hole mass.
It's easy. Buy expensive jewelry and bury it in your garden.
That one is easy: 2^(2/4) :)

I fail to see how is that different.

Actually, VMS supported versioned files back in about 1987.
