The magnitude of earthquakes is a function of cross sectional area, average slip, and shear modulus of crust. Strike slip fault earthquakes rupture very near the surface. We can have a few hundred kilometers worth of rupture, but for some reason ruptures never happen along the entire length of the San Andreas but small portions of it (we've seen ~300 miles with the 1906 EQ). So there are limits to how large an earthquake can be on the San Andreas mostly because of limits to rupture lengths and the shallow depths of earthquake epicenters.
If you were to rupture the entire southern San Andreas fault, you could get up to ~8.5. But that is may be unlikely. Crust in California is not homogeneous. Some parts of the crust can take way more stress than others. Some parts are constantly moving, preventing massive build ups of stress (e.g., around Parkfield), which may prevent a serious rupture in the area.
If you look at earthquakes over many years, it's random. Humans love to see clusters. Actors die in threes. Airplanes crash in threes. It's what we do.
Will a major earthquake happen on the San Andreas? Yes. Can we say when? No. Be prepared, but don't fear monger based on tenuous "global patterns" that have not been vetted by any peer reviewed science. Notice the probabilities in this new item. That is not prediction. It works like the 100-year flood. We know it'll happen based on "reoccurrence" intervals (which for earthquakes are more tenuous than for floods) and can assign a probability. We can know that there are a lot of stress on faults and know that a fault has not slipped in a very long time... but we can't know when the rocks will break.
I used The Teaching Company's Algebra series to get my math skills back -- with great results. I was in the military for 6 years, my brain was very idle, but I wanted to separate and go to college. I had terrible grades in High School. I used their algebra series to relearn everything and, when I finally left the military and started college, I had terrific results. While I did take algebra courses in college, I managed A's in all of them and also 1 A in Calc 1, and Calc 2 & 3 ended up with Bs. Frankly, that's pretty damn good in my opinion. The trick, of course, is actually completing the provided workbooks.
I'm almost sure that I did not have to retake those algebra courses but I had prereqs to fulfill.
I completely endorse Teaching Company's algebra products (well, the 2005-2006 versions, anyway, looks like they have changed their instructors:-(...)
It is nearly impossible to take notes using an electronic device in geology courses. As the OP mentioned, diagrams are rather difficult to draw quickly and effectively on electronic devices. Thus I use a pad of engineering paper to write all notes and draw all diagrams. The exception occurs for those times when the lecturer posts slides online beforehand and *never* draws on the blackboard. If necessary I convert to PDF and then use PDFXChange Viewer to annotate, highlight, and draw *very* simple diagrams or point out important parts with arrows. It's nice to have notes directly on the slides and it saves me time since I don't have to correlate notes with each slide during study sessions.
The tablet industry needs to prove that tablets can be fast and accurate when taking notes and diagramming.
I have to warn, however, that if you do not have access to the journal Earth & Planetary Science Letters on your campus, organization, or local library, you will hit a pay-wall.
For those that are interested in considering scientific paper without the media filter:

I sure wish that secondary sources properly cited primary sources, even if they are only interviewing the main scientist involved. Giving the journal name and date as Discovery News did is a good step, though.
So if this is a coarse grained rock with a basalt composition, then I guess that means it is a Martian gabbro (on earth they tend to be used ornately as black "granite" countertops). Which is highly interesting because that may indicate crustal deformation. Here on earth, such rocks form deep in the ground in what we call plutons. These are pockets of magma that differentially crystallize into grabbros and granites. Plate tectonics nudges them to the surface and weathering + erosion helps to uncover them. The Sierra Nevadas is a continuous grouping of them called a Batholith. Yes, all that granodiorite use to be underfoot!
Anyhow, this could be important in perhaps proving that, yes, at one point, Mars had active plate tectonics. Planet formation kind of requires it but good to know Mars may have had some crazy earthquakes in the past uplifting such rocks to the surface.
Well, even U.S. scientists are very careful about the potential for organic contamination. Hopefully the satellite isn't simply detecting something deposited onto the detectors or nearby areas on the spacecraft. Carbon and oxygen are all over the universe, so even if contamination isn't a problem, detection of organics on the moon is not a surprise. To give an idea about the abundance of carbon, very large stars may end up in a carbon-nitrogen-oxygen (CNO) burning phase once they're used up all their heavier elements.
What is really of interest is what organic molecules have been found. Amines would be exciting; particularly if they are amino acids.
I'm no geologist (yet) and I have only looked superficially at this but the feature reminds me of what can be seen with columnar jointing. Nature can be amazingly precise and geometric sometimes. Normally it's basalt, and the ocean is pretty much basalt at the top-most levels of the ophiolite. If the basalt cools from the exterior, this can happen. I don't know if this can occur in the ocean as we tend to get pillow lavas as the basalt cools INCREDIBLY FAST and kinda oozes out. Also, with the extent of this feature, this would have to have been some sort of flood of basalt.
It's a pretty neat feature, real or unreal. Although I have to wonder what these people think about the very long linear feature called the Ninetyeast Ridge in the Indian ocean. Anyhow, got to love the masters of pattern: humans. Never fail to see things where there's really nothing.
I bought a 2004 Ford Focus ZTS PZEV in Utah. It was the only one on the lot. I wonder if they were not supposed to sell it? I do know that the salesperson that sold it to me left the dealership shortly after.
I live in California now and I'm pretty happy with it, though it has no State provided benefits like the toxin trap that is a Prius..000066667lbs of pollution per mile is pretty damn good if you ask me, especially considering most cars pump out around 1 pound of emissions per mile. I have only 9000 miles on the car.
I wouldn't be surprised if the car is more efficient than an incandescent light bulb!
But the fact it is burning gasoline is still a problem that cannot be ignored. I'm helping to legitimize wars, you know? At least it is not a Hummer.
I've been using the marble mouse for as long as I can remember... it is a perfect device and is inexpensive. They last forever too. I don't remember why I had to buy a new Marble mouse but fortunately it was available when I needed it.
A lot of modern trackballs are made for right-handed people and that's just not cool! So the basic Marble mouse, which has merely two buttons and the marble in between, is perfect. I hope it never goes out of production, and if it does or has, that there are stockpiles lasting centuries!
Whenever I use a regular mouse, my wrist starts freaking out. I dislike them so!
They provide tested scripts to roll your own packages. So you know what you're getting into and that it will work with your individual Slackware installation. They've worked very hard to prepare for Slackware 12. I think they were the first, in fact, to be ready for Slack 12.
Now we just have to fight "if you're not doing anything bad, you've nothing to hide" -- in a country such as ours, that is heresy against our constitution and the people who live under it. Our general need of having privacy and not being exposed to the world is a natural one and must be protected at all costs. Those who seek to undermine this principal are very treacherous indeed.
So far every Korean I've ran into here in S. Korea has a Cellphone and Broadband. Nearly every shop I walk into there is a computer hooked up for surfing during the day's quiet hours.
Here in Korea, when you get cellphone services, they talk to a representative via MSN Messenger or suitable application to activate your line in real-time without having to pickup a phone.
Osan AB has broadband through out all the dormitories, though SSRT (Samsung Rental) has a monopoly on that so they get away with charging insane costs. Something like $45 just for DSL... and really horrible TOS threatening $1000 fine for running anything resembling a "server." But 300kbps downstream is rather nice coming from the States where I'd be lucky to hit 90kbps.
I was able to whipe my root partition of Slack 9.1, install Slack 10, overlay my old known modified/etc/ configuration files onto the new system, and be ready to go after installing a handful of unofficial desktop packages. Apache w/https, samba, nfs, iptables, courier-imap, and so on. Basically, all server functions were available within less than an hour after install because the infrastructure of Slack 10 remained the same as Slack 9.1. That to me is absolutely critical to my happiness.
The compile environment is top notch and so zero problems occured while packaging software from source (such as courier-imap). Everything went off without a hitch. I attribute that to lack of automated configuration systems and keeping everything virgin. I'm glad LILO is still being used, because in Debian-Testing, when selecting to use XFS for the root partition, it complains that GRUB may have issues. I'm glad Slack is keeping it real:-)

Considering that my 1280x1024 LCD displays has no dead or constantly activated pixels... Sony has no room to talk.
Seems to be just a cost cutting measure at Sony. QA to rid of jacked LCD materials essentially keep prices high for displays.
