From the Reuters article (referring to 2600's
DeCSS case):
In that case, the Recording Industry Association of America (news - web sites) and the Secure Digital Music Initiative claimed 2600 Magazine's online publication of a program called DeCSS (news - web sites) (Decrypt Content Scramble System), that cracks encrypted digital video discs, violated the law.
That case has nothing to do with RIAA or SDMI, but
instead involves the MPAA.
Its kind of sad when reporters don't check their
facts.

I think you could still use a lithium blanket, but
I think that the lithium blanket is for breeding
tritium. Lithium is 92.5% Li-7 and 7.5% Li-6.
When either isotope of lithium absorbs a neutron,
a Tritium nuclei tends to be produced. But when
Li-7 reacts with a proton, 2 He-4 nuclei are produced, and when it reacts with Li-6, Li-7 is usually produced (after Be-7 captures an electron).
He-3 may be a possible outcome of neutron reactions with Lithium, but I think the main product is tritium. Anyway, in order to have enough
neutrons around to react with a lithium blanket,
than you lose have toone of the advantages of D/He-3 - fewer neutrons.
Anyway, I may be recalling this incorrectly, but I don't think that you expect to
get much He-3 from a lithium blanket.

Well, if the fusion reactor uses D/He-3 fusion
mentioned elsewhere in commments here) instead
of D/T, then it is possible to avoid the steam
cycle. D/He-3 reactions yields a proton
(instead of a neutron) as one of the products.
The electrical charge of the proton can be used
to trap its energy electrical, and avoid the
step of heating water.

The problems you describe with neutrons are limited to fusion reactors that rely on
Deuterium/Tritium fusion, which produces
neutrons as a product. Deuterium/Helium-3
fusion produces protons instead of neutrons
(D + He-3 -> p + He-4). It would be much
easier to harvest the energy from D/He-3 fusion
and the reactions involves less radioactivity.
The downsides are that the D/He-3 reaction has
a higher energy threshold, so it requires a better
confined plasma to make D/He-3 energy production
plausible. Also, the supplies of He-3 on Earth
are limited. Of course this disadvantages leads
to a interesting convergence of interest between
fusion research and space exploration. There's
plenty of He-3 (deposited from the solar wind)
on the moon. So He-3 mining could be powerful reason to maintain
a base on the moon.

Not all nuclear weapons have been fission/fusion hybrids. The first weapons (like the ones used
at Hiroshima and Nagasaki) were pure fission weapons. They were powered by run away fission
reactions of uranium or plutonium.
More recent, nuclear weapons (probably
including all of the weapons in the arsenals
of the major nuclear weapon countries - but
not of the minor countries) are fission fusion
hybrids - or H bombs. A "small" fission explosion
igniting a fusion in a core of deuterium and tritium (hydrogen isotopes with one and two
neutrons respectively).

I can do (and have done) all of the things you mention with this
Solaris work station I'm sitting at Star Office,
and IE for Solaris.
Of course IE for Solaris is an abomination
and I only used to see if it would run. And Star
Office isn't any great shakes (though I hear Open
Office is making great strides), but it works well
enough for looking at Word and Powerpoint files
(most of the time).

Right. I was thinking in terms of the stricter
definition of essentially c (gamma = 1000), but
that definition is probably too strict. Of course,
the most interesting stuff moving near c is cosmic
rays. Energies above 10^22 eV - that's fast.

Yes. Various astrophysical processes (and even
some accelerators) create protons and electrons
(and more exoctic languages) that have kinetic energies 1000 times their rest mass.

I hope we shall crush in its birth the aristocracy of our monied corporations...
The problem is that right now, it would be very hard to come up with a way to give a neutrino low
kinetic energy. The excess energy available for
kinetic energy of the reaction products is on the
order of MeV, while the limits on the mass of an electron neutrino is on the order
of eV. The way the physics of nuclear reactions
works makes it very difficult for the neutrinos
to get a million times less kinetic energy than
the other reaction products. In fact, due to the conservation of momentum, its more favorable for
the low mass products to get more kinetic
energy than the high mass products.
Even if you could get low energy neutrinos ( less
than an eV), you'd still have to collimate a beam
them. That would be very difficult to do, since
they react so little.
So yeah, its not impossible to measure the mass of
a neutrino directly. But I'd be very surprised if
we find a direct way to measure the mass of a
neutrino anytime soon. Indirect will have to be good enough for a while.

When I was in high school, I was 'taught' that electrons had no mass. It is commonly held today that they do. It was assumed, I assume, that they did not have mass because it couldn't be proven that they did, since there was no way at the time to measure it.
Well, you must have gone to high school a really long time ago. As long ago as 1897
J. J.
Thomson determined the charge to mass ratio of
electrons and estimated that the mass of an electron was 1/1800 the mass of a proton. About 15 years later Millikan determined the charge of an electron, which allowed for better measurements of the mass of an electron.
--
I hope we shall crush in its birth the aristocracy of our monied corporations...
Well, the mass of neutrinos is so small and they
interact with other matter so sparing that its
almost impossible to tell the difference between
their speed and c. The typical total energy
of a neutrino is going to be at a thousand
times (and probably a lot more) times its
rest mass. A particle with a total energy 1000
times its rest mass has a speed of about.9999995 c, which as you can imagine, is pretty
hard to differentiate from 1.0 c .
So, neutrinos don't travel at c, but its pretty
darn close.

OTOH, there was a huge THOU SHALT NOT USE OPEN -SOURCE TOOLS TO DEVELOP mentality,
This is probably because if any open-source software found its way into their commercial product, they would be legally liable for various license violations.
Using open source tools wouldn't cause any
licensing violations. Using the source might, but
that a whole other kettle of fish.

Well, MATLAB (and IDL) might have nice plotting
routines, but their matrix handling isn't any better than F90/F95. So for really tough numerical problems using F90 to create the data,
and your favorite plotting package (MATLAB, IDL, or if you like free PDL or GNU Plot) is the way to go.

This is hardly your usual strict constructionist
group of justices. Scalia, Thomas, Souter, Ginsburg and Breyer voted together in the majority. That's a very strange combination. I didn't know Thomas ever voted against Rehnquist.
As for possible Bush nominations, this is one area
where I hope he's like his Pa. Another nice independant thinker like Souter would be nice. The court doesn't need to become any more polarized.
All these 5-4 decisions are bad for the law, since
every time there is a new justice there's a possibility that almost identical issues could
be revisited.

Hey, I agree that the slashdot crew could be
more responsive about this stuff. Its probably
about time for another state of slashdot interview
(or IRC meeting). As for the difference between
a +3 and +5 post, I don't think that's too big
a deal. Both posts were in the same thread, so
unless you're viewing slashdot at +4 or +5 threshold, you'd probably see both.
I think some
people around here tend to get too worked about
the way slashdot runs, and tend to jump to conspiracy explanations too quickly.
Thanks for the hint about links, I was trying the
sid form. I still can't find the other explanation about web bugs. Maybe it got modded down.
