Yes, here are the details from the USGS. As someone else already pointed out, the depth of 0 km makes it pretty clear this wasn't a natural quake.
USGS says the quake was at 41.294N, 129.134E. According to Google Earth, it's a fairly mountainous region, at an altitude of about 4800 feet. It's within a rectangular region, about 31 kilometers north to south by 17 km east to west, that's at much higher resolution than its surroundings; I'm guessing that means somebody was already very interested in that particular area.
I've been trying to figure out the yield from the quake magnitude. One site says a 1 kiloton nuke could produce a 4.0 earthquake -- but the magnitude of the quake can be reduced considerably if the nuke is set off inside a large hollow chamber. North Korea had previously said they were going to use an abandoned coal mine. On the other hand, they obviously weren't trying to hide it.
Yes, I use a similar Registry hack to do the same thing on my Windows systems, so both Caps Lock and Control act as control keys.
Personally, I can't stand having the control key anywhere other than immediately to the left of the 'A', and I use Caps Lock rarely enough that disabling it altogether isn't a problem for me. I've tried to adapt to other layouts, and I can get by, but it never becomes comfortable.
These are my own prejudices, and I wouldn't want to impose them on anyone else.
The problem with the registry hack is that it applies to anyone using the machine. If I were using a shared Windows machine with multiple accounts, I wouldn't be able to set it to work the way I like without inconveniencing other users. Fortunately, the two Windows machines I use aren't shared with anyone else.
This should be a per-user control panel setting. It's a common enough quirk that Microsoft should expend the minimal effort required to cater to it.
Typical Old-World Europe thinking. They "discovered" America too.
Way off-topic, and taking the parent article too seriously, but...
It's likely that Europeans were the first humans to discover America. According to some research, they came across the Atlantic ice sheets during the late Pleistocene.
If you're running something Unix-like, you should be able to set up an ntp daemon.
But I've always wondered why devices that run off 60-Hz line current (in the US, anyway) have trouble keeping their clocks accurate. Sure, that doesn't help if the machine is unplugged, but it should be more than accurate enough whenever it's plugged in. (The utilities go to a lot of effort to keep 60-Hz AC in sync; why not use it?)
The decision stemmed from the work 200 years previously of the first English Astronomer Royal, John Flamsteed, who calculated that the Earth rotated on its axis once every 24 hours.
So he was the first person to notice this? How lucky for him that an hour already just happened to be 1/24 of a day!
I wouldn't take the rawstory.com story too seriously.
For one thing, the author seems to think that "Grid" and "TeraGrid" are the same thing. A Grid is a generic term for a set of computer resources, possibly spread across multiple administrative domains, working together using Grid software (such as Globus http://www.globus.org/). The TeraGrid is one specific Grid project.
Beyond that, I don't know why he thinks the Department of Homeland Security has anything to do with this. The TeraGrid is not, as far as I know, used for classified research. Yes, Argonne National Laboratory is a TeraGrid site, and I'm sure they do classified work as well, but there's no reason to assume there's any connection between the two.
The TeraGrid has the same security concerns as any other large computer system: maintaining the integrity of users' data, keeping intruders out, and so forth.
A single-threaded Perl script would use one CPU on one node. The individual CPUs are pretty good, but only comparable to, say, a modern high-end PC.
If you wanted to run 500 copies of your single-threaded Perl script, they'd probably all finish in about 4 minutes -- but that doesn't make very good use of the system. You could get the same results using something along the lines of SETI@Home or distributed.net.
What makes TeraGrid special is that it's a whole bunch of CPUs (along with lots of memory, disk, and archival storage) connected by high-speed networks, with a lot of hardware and software infrastructure to make it work together. This is good for things like weather simulation, where the problem can be broken down into pieces, but the adjacent pieces need to communicate with each other.
That would be a great idea -- if the major bottleneck in developing new sources of energy were a shortage of computational cycles. I'm no expert on the subject, but I'd be surprised if it were.
USHRT_MAX has to be one less than a power of two on any system that uses binary integers (i.e., on just about any system in the real world); 65535 is the minimum allowed value. It's not a significant limitation; if you need bigger numbers, use a bigger type.
For various reasons, the number of nodes in a system is often conveniently some power of 2.
The fact that USHRT_MAX+1 and the number of nodes in the BlueGene/L system happen to be the same power of 2 is purely coincidental. It's conceivable, I suppose, that something is using a variable of type short as a node index, but I doubt it.
UNIVAC was the name of the computer, not the company.
Looks like you're right.
The UNIVAC was introduced by Remington Rand. Remington Rand merged with Sperry in 1955 to form Sperry Rand. Sperry and Burroughs merged in 1986 to form Unisys.
Why on Earth was it necessary to design this thing to work with any particular browser(s)? It should have been easier to design it to conform to all the applicable web standards; operability with all conforming browsers then comes for free. If IE or Firefox uses some non-standard feature that's not supported by other browsers, you just don't use that feature.
I'm tired of web sites telling me to "upgrade" my browser to MSIE or Netscape. They should upgrade their web sites to the World Wide Web.

Using this for cameras sounds cool, but I want adjustable eyeglasses. I have bifocals and a separate pair of reading glasses. I want something that either automatically focuses on what I'm looking at, or that I can easily adjust, say with a small knob on the side. (My own lenses used to do that for me, but my eyes and I were younger then.)
Obviously we're not there yet, but I'm looking forward to it (though with some difficulty).

No, Rocks isn't overkill for a 4-node cluster; I'm running three 4-node Rocks clusters myself.
I'm not familar with other solutions, but Rocks is remarkably easy to install.
There are plenty of sources closer to us that require less bells of whistles. Thermal (amplifier) noise? Radioactive decay?
Or a really hot cup of tea.
You know this is why people are loosing interest in the space program! Useless findings after useless findings are boring people to death.
They found a new planet, 13 times the mass of Earth, and you're bored?
Sheesh!
What the hell does a "super-sized rocky planet" mean?
In this case, it means it's a rocky (i.e., Earth-like) planet with about 13 times the mass of Earth.
The article says so. (You don't expect to see all the information in the headline, do you?

Why can't you run Java?
The TeraGrid has several large IA-64 clusters (mostly running SuSE Linux); as far as I know, Java works just fine on them.
If the FBI has time to spend on this, it's obvious that the War on Terror has been won. Because otherwise, this just wouldn't make any sense at all.

Um, no, Univac was a real 20th-century computer company (later merged into Unisys). Asimov probably named Multivac after Univac, not vice versa.
