The rock vapor will move away from the sub stellar point towards the terminator and condense at some ring shaped region. Rock being a solid can't just flow back to the vaporization point (like a water ocean would) so it just piles up.
At some point, the rock ring would get big enough to sink into the planet at the same rate that the rock dust is falling.
Eventually material would be transported through the bulk of the planet by pressure rebalancing to evaporate again and the cycle would repeat.
It might be possible that the rock ring and the void on the day side would throw the mass distribution off enough that the locking to the star would change angle after a while.
Yes, but the ABM treaty of 1972 was signed with the USSR, which ceased to exist when the USSR dissolved in 1991. There was a "memorandum of understanding"
signed again in 1997 with four of the states that came out of the remains of the USSR but the US Senate never ratified it so it's not official.
Later in 2001, the US pulled out giving six months notice as allowed in a clause in the original ABM Treaty.
My whole state of Maryland only has one Microcenter and it's miles from me. Microcenter seems to have very conservative growth plans. I'm hoping this will interest them in moving into the void left by Circuit City, MC is way better than BestBuy or Circuit City.
One way to reduce that problem is advanced nuclear plants that run at high temperature. In periods of low demand for electricity these can divert energy production into making hydrogen via the thermo-chemical sulfur-iodine cycle. The hydrogen can then be stored.
The so-called climate scientists interviewed in the article are mostly oceanographers, engineers, museum directors and authors.
It looks like only about half are literally climate scientists/physicists.
I'm in central Maryland and I can report there are plenty of acorns here
(we have some oak trees at work, they drop acorns all over the sidewalks and
parking lot)
This might spoil the tin foil hat party but all these changes are almost certainly due to market forces and the growing ubiquity of network hardware and services getting much cheaper after the 2000 bubble hit and companies were forced to reduce prices and cut back on pie in the sky stuff and concentrate on basic network service. The article bandwidth plot showed the decreasing trend in bandwidth started in 1999-2000 before 9/11 and the
Patriot Act.
Plus as developing nations build up their networks, they're going to go the cheaper route, they don't have to go to the US anymore because this hardware is all a commodity now. It's cheaper to reduce unnecessary connections and keep your services closer, if Egypt wants a international connection they can get less latency by going to Europe than the US, ten years back there wasn't a choice.
The article says "in the next century" new telescopes will come online to track these threating asteroids. I really doubt it's going to take until the 22nd century for these telescopes to arrive. Don't they mean this century?
There's an obvious issue I see here as to why there's this 15% difference.
Freebsd 7 has jemalloc but the older Linux kernel they tested didn't.
Linux will get jemalloc in the near future. It would be interesting
to retest these benchmarks with both sides having the new malloc.

When I was just recently at the Detroit Airport, they
were showing a NFL football game on a huge set that had to
be bigger than 55". It was not in a sports bar but out
in the concourse on a wall. How do they get away it?
I replied but didn't see it show up so here's the 2nd try,
Another possibility would be Argon, it's less leaky than Helium.
But molten lead or salt seems to be better at avoiding the chemical reactivity
as someone pointed out. You'd think if sodium was so much trouble
it wouldn't be under research for Gen Iv reactors
http://en.wikipedia.org/wiki/Generation_IV_reactor
Why does it even need to be a fire hazard, can't they flood the
reactor building with a non-reactive gas like
nitrogen or CO2 (or much more expensive, helium)?

There is a scary possibility, look at our own inability to get fusion to work,
oil/chemical energy is ok to just get a civilization started but to
go from star to star you at least need fusion. In fact each planet might only
get one chance because the first civilization could easily use up all the
easy to reach oil and coal. If the first civilization dies off, the next one
to come up has no easy to use starter energy to run their technology
long enough to even get a shot at researching fusion.
For example the hot, jungle like conditions that created our oil and coal might never come again.
It's possible that there's is no way to get fusion to work. So everywhere in the universe are lots
of civilizations that then have energy crises and either learn to live
efficiently (using piddling fission power, wind, and other renewables) or just die off.
This makes them much harder to detect.
Even without fusion, it might be possible to go from one star to another very
slowly via advanced fission propulsion (taking centuries in slow boats to go from
one star to the nearest star with robots growing the crew as the ship approaches
the target star out of frozen ova or some other even farther out nanotech
method)
http://en.wikipedia.org/wiki/Fission-fragment_rock et
but doing that just clones your power starved civilization on another
star and doesn't solve the energy problem. The only thing it really
does is reduce the chance that one disaster will wipe out your only
planet.

I think it's unlikely that the base commander would show something this
top secret to a lowly press officer. Think of it this way, suddenly a
UFO shows up, the Feds charge you as the Base Commander to clean up the
site, hide the UFO and bodies and most of all, try your best to minimize
the number of possible leaks of this information. So you're not going
to go out of your way and show the stuff to the base press officer.
He has no need to know, it would be better for you to feed him
the same cover story as he's going to give the press.
Ah no I don't, I didn't that I did. NSA does have lots of normal offices and power saved there
by using dpms and other power reduction tactics can lower demand so power can be allocated to the
headless mainframes... DUUH. Pull your own head out.
Where I work we have thousands of PCs and so many times when I walk past an
office I see a OpenGL or some other pretty screen saver running. This wastes
a lot of power especially if the display is a CRT. If they just made
sure to go to full suspend/power off dpms on their displays and setup
the PCs for standby/suspend they could save a lot of power.
The smart design would not have the enzymes in the main tank, you'd have a
big tank to hold the starch and a smaller separate reactor into which
starch would be dumped in metered amounts as it's needed.
Think of a coal fired electric plant, they don't light the huge pile of
coal on fire in one go, they auger the coal into the furnace at the
rate it's actually needed.
The US *is* getting rid of nuclear weapons. By the Treaty on Strategic Offensive Reductions,
the US is scheduled to reduce that 5021 to 2200 by year 2012
The W62 retirement started in October 2006, W87's taken from decommisioned MX missiles
will replace the older W62's so those Minuteman IIIs will have those warheads.
No new nuclear warheads have been built in the US since *1989*
Even the "designing new nuclear weapons" comment you make needs a
addendum, I'm guessing you mean the bunker buster B61 Mod 11.
If this was even done,
this is not a building of a new warhead but just reusing an
already existing B61 warheads modified to tolerate the impact of
ground penetration. There is also a life extension program,
this is needed because as you reduce your total stockpile,
due to warhead aging you have to rebuild some of those to
keep the reduced stockpile effective. Arsenals aren't every
good for deterrent if the enemy doesn't think you maintain them
thus causing a 90% failure rate. Also, if you don't
rebuild warheads, the engineers eventually go off and find
other jobs, warhead construction/rebuilding is nearly an art. You don't
just go get anybody to do this. The submarine industry has the
same problem, if the pentagon completely quits making subs
because the cold war is over, the engineering base will dry
up. Eventually we'll need to replace a submarine or two and
will find no industrial base there to do it.

What would save businesses a lot on power would be to not install any OpenGL or
other fancy screensaves but only setup the blank screen DPMS style ones that
actually suspend the screen when the machine is idle. I see screens all the
time at work that run screensavers keeping the display from going
to sleep. The savings would be about 100 watts per display for CRTs and
maybe 50 watts for LCDs. Also, I bet lots of video cards in dpms probably
draw less power and the cpu could go deeper into powernow or whatever
power reduction.
Maybe we should make BIOS flashing a bit harder and have a
hardware switch or jumper on the motherboard that has to
shorted for flashing to occur. That way it the rootkit
attacking the bios or firmware via software would not
work.
