The Union is not and was not the problem in this case. In 1981 the Union was right and Reagan was very lucky that there wasn't a major air disaster because of his actions. As was the case for basically every action of that Administration, ideology triumphed over both reality and common sense.
A little overstated.

I fly every week, I have never seen a case of air rage, and I have never lost a bag. I think that the case is over stated.
It is true that there are too many small flights, which waste both gas and airport slots. But the overall system works decently well IMHO.
Have we reached a time where all of our tool-sets are now made moot by vast clouds of information and strictly applied maths?
No. And also no to the basic premise of the article.
Meteorologists have been doing this for decades (principal component analysis has been a crucial tool there since the 1960's, and correlation analysis has been used in some form since the 1920's if not earlier) and so have the astronomers. Oh, and the particle physicists have been sifting data in their own way on a big scale ever since World War II.
As one of many examples, if you ever have heard of an "El Nino event," that was discovered through correlation analysis and is best understood through principal component analysis. BTW, the original work predates electronic computers and was all done by hand. The vast quantities of meteorological data require statistical analysis to make any progress at all, but that certainly does not mean that you cannot use the scientific method.
So, no, this does not invalidate the scientific method. In the Internet jargon, science scales.
No, it's just that as a practical matter he could stop it. If someone was drowning in a river, and the Senator was standing by with a rope and life preserver, it is not attributing him the powers of the deity to ask him to throw the life preserver to the victim, or to be critical of him if he doesn't do it.
IMHO, only live hard drives is archival storage - and such data needs to be backed up somewhere offsite.
Tapes, CD-ROMs, DVD-ROMs, etc., are good for backups, but not archival purposes IMHO. Even if you have a plan to read every disc after 5 years and re-write it onto something new, you can expect a certain number of failures.
Of course, for truly long term storage, baked clay tablets and incised granite are probably your best bet.
As the new de facto leader of the Democratic Party, and as a Senator, Barack Obama could stop this with a word. What will he say ? Will he stand up for liberty ? Or betray it before he even gets elected ?
The ISS has lots of fans. Listen to a TV broadcast from there sometimes.
In space, the use of heat pipes is also fairly common - I wonder when this technology will start being used with blades in colos, given the density you can rack mount blades.
Delay Tolerant Internet (or DTN) is the current version of Vint Cerf's "Interplanetary Internet" - basically, making a TCP-like protocol in situations where there may be long delays and no end-to-end connectivity. I thought that there was a test of this on a shuttle flight but cannot find a link, Vint Cerf last year talked about a test in 2010.
To me, that is a lot more interesting than just having a switch in LEO.
And the developers, who used the C programming language to build their own software for a Linux operating system, are expected to be dealing with that challenge for about three months
That, to me, says that they wrote the command software in C, not that they use C to program the lander.
However, if they did, it wouldn't be unprecedented - Forth is used to control a bunch of satellites and astronomical gear, and in my experience you do have to write Forth programs to get things done in that environment. The old Viking Landers were controlled by writing in assembly language, which is even worse, and which eventually killed Lander I, when bad commands were sent to the Lander after everyone familiar with the computers used had been let go.
During World War II the Swedes intercepted German traffic from Norway to Germany proper going over Swedish territory, and broke the T-52 encryption to listen in to what they were up to. I don't think that the Germans ever had a clue.
There are enough loopholes in the general theory of relativity to allow antimatter to fall up rather than down in a gravitational field.
Uh, no there are not. Gravity (or geometry, same thing in the theory) depends on mass energy in General Relativity. Stuff (with mass energy) follows the metric (the local geodesic). Even photons (which are their own anti-particles) follow the geodesic - and that has certainly been tested. Equivalence principle tests also show that different sorts of nuclear matter (including neutrons) individually follow the geodesic. Anti-matter certainly has mass energy, and (with matter) can be converted to photons and is no different in the theory. In other words "there is only one type of geodesics and there are no antigeodesics for antimatter."
The original article talks about "flavors" of General Relativity. Ain't so such beasties. Period. If you go to the real original article, you find a proposal for a 1% test of the equivalence principle for antimatter, and no such claims of flavors. Now, the equivalence principle has been tested to better than parts per trillion, and part of the mass energy in ordinary matter is made up of antimatter (in virtual particle pairs), so (based on the experimental evidence) I would claim that this test will be negative and is not actually that interesting as new physics. (The articles say that these older tests are "model dependent," but they are not model dependent enough to matter for this.)
That doesn't mean that this shouldn't be done (everything should be tested in physics, and different tests are always useful), but the prediction of General Relativity is clear : if anti-matter has anti-gravity, then General Relativity is wrong. The experimental evidence is also clear : this isn't going to be accurate enough to matter. Will make for some good public relations, though.
Switch and Data is already in the colo-exchange point business in a big way. I wonder if Switch Communications has already received their cease and desist letter.
Well, when you have these kinds of blatant typos it means the poster might not have any idea what he was talking about. In that case, it cast doubts on whether it's really a "world changing experiment"... Exactly. Let's see, a report full of errors about a Italian economics journal reporting on a Japanese experiment. Doesn't give me confidence.
Reading the second article does not give me confidence. It is the same old "we did this and that and got out some heat and some Helium." This also does not give confidence.
The article talks about Deuterium (Hydrogen-2) and Helium-4. Deuterium - Deuterium fusion should give rise to Tritium (Hydrogen-3 - which is radioactive) or Helium-3 plus a neutron (which is a form of radioactivity). Now, either of these products (Tritium or Helium-3) can themselves fuse (with each other or with Deuterium) to produce Helium-4, but these should also produce neutrons. Deuterium - Deuterium fusion to directly to Helium-4 is much harder to do (it has a very small cross-section), and its energy should come out as gamma rays.
So, they claimed no radioactivity (when there should have been neutrons or gamma rays produced) with an unlikely nuclear reaction (H2 + H2 -> He4) and it produced a moderate amount of heat (1 kilo Joule) without actually stating how much energy it took to run the apparatus.
It may be real, but the indications in this Italian economics journal are not encouraging.
I don't know how many people here know this, but a UK citizen was arrested and sentenced in Dubai for 3 milligrams of cannabis. Once people can get arrested for microgram or smaller levels of anything, no one will be safe, since no one will be able to tell if they haven't been exposed at that level, and it will be very hard to verify that the vanishingly small evidence was indeed what was claimed.
Analysis of the Viking and Pathfinder tracking data showed that Mars does have a core, and its approximate size. This was presented in Science, Vol 278, pp 1749 - 1751, 1997.

They look older, yes, better, IMHO, no.
Because a way of getting to the Wnauts is through these lawsuits.
Do you really think W is fighting this out for the telcos ?
W is worse than Nixon, by a good measure.

I suspect that in a few decades, estate planning will include what to do with the family terabytes.

Different bill. There will be a Senate vote on this (unless it gets Filibustered).

We used the Uranium gun type bombs for artillery launched munitions. I beleive that the W9, W19 and W33 were all US gun type weapons.

The Amateur Radio satellites went to an Ethernet backbone some time ago - over a decade IIRC.

A brief search on the subject reveals this
we conclude that the Principle of Equivalence between particles and antiparticles holds to a level of 6.5, 4.3 and 1.8 x 10-9,
Just a little bit better than 1%.

Prior to the Hoover Dam coming on line (i.e., pre-World-War II), there wasn't a city there.

Yeah, but that modeling change is trivial. The poster is correct; Tharis proves that the crust is rigid.
