Comment: Where are all the foreign scientists? (Score 2) 226

It used to be that most of the scientists from US universities I met at international physics conferences or summer schools were green card holders or recent immigrants. There were hardly any american born ones. Did that change in the last 20 years or does the show slightly misrepresent that ratio.
I am asking because in his way Sheldon reminds me of some Russian physicists I used to know.

that I used for my paper 15 years ago. It is on a tape, that is somewhere in a drawer, that I have no tape drive for. On the other hand, the LaTeX file and the C and FORTRAN programs I used to evaluate and create the data and write the paper are still on a hard drive that is running on a computer in my network and I can access it right now. I probably can*t compile the the program without change (was written for Solaris and DEC machines) and maybe not even run LaTeX on it without getting some of the included styles, but still it is there.
Since my work was in theoretical physics and numerical the loss of the raw data is probably not as bad as long as you still have the software, but I guess for an experimental physicist the problems would be much greater to keep the massive amount of data they sometimes have and if lost to reproduce the data.

the nvidia-settings tool to set up 4 monitors on my GTX670, there is no problem with speed and I get hw accelerated 3d on every screen. The driver is NVidia's 310.19. I used the TwinView Option on the Layout selection screen and could put the monitors into the wanted configuration with the GUI. I can move windows between the monitors and xfce gives me panels on the separate monitors.
The screen section in the xorg.conf looks like this:

if you forget part of the energy-momentum tensor when you transform your coordinates from a stationary into a moving frame of reference.
Special relativity really cannot "clash" with the Lorentz force law, because it is based on the Lorentz invariance of Maxwell's equations. I think a "paradox" like this keeps coming up ever so often in discussions of special relativity, form people who don't understand it. I just don't see how PRL can accept such a paper.
I admit it would make a nice problem for a physics test, but not much more.

I saw the camera on NHK World and it is not what you may think is camera sized. It is a big cube with about 1 m sides. It also includes a small optical camera, so that you get a composite of the visual picture and the gamma radiation distribution. It is supposed to be used to check the buildings in contaminated areas and see where the radioaktive material is located.

US Government Sets Up Online "App Store" 138

Posted by samzenpus

krapper writes "The Obama administration has unveiled a government 'app store' designed to push the federal bureaucracy into the era of cloud computing. The change means some federal employees will begin using services like YouTube, Gmail and WordPress, which store data on private internet servers instead of on those paid for with public money. The process will start small but will ramp up quickly, Vivek Kundra, the US chief information officer, said in a blog post on Tuesday. 'Our policies lag behind new trends, causing unnecessary restrictions on the use of new technology,' Kundra writes in the post on WhiteHouse.gov. 'We are dedicated to addressing these barriers and to improving the way government leverages new technology.' The app store is designed for federal employees doing official government business and is not intended for use by the public."

They already did that for the last world cup.
You had to register for your ticket and you could not give it away. So they could check if you are the person that ordered the ticket. I don't remember if they already had a chip in the ticket, but when you can check the serial number against a database, you really don't need a chip.

McAfee Worried Over "Ambiguous" Open Source Licenses 315

willdavid writes to tell us InformationWeek is reporting that McAfee, in their annual report, has warned investors that "ambiguous" open source licenses "may result in unanticipated obligations regarding [McAfee] products." "McAfee said it's particularly troubling that the legality of terms included in the GNU/General Public License -- the most widely used open source license -- have yet to be tested in court. 'Use of GPL software could subject certain portions of our proprietary software to the GPL requirements, which may have adverse effects on our sales of the products incorporating any such software,' McAfee said in the report filed last month with the Securities and Exchange Commission. Among other things, the GPL requires that manufacturers who in their products use software governed by the license distribute the software's source code to end users or customers. Some manufacturers have voiced concerns that the requirement could leave important security or copyright protection features in their products open to tampering."

Submitted by Hello7
Hello7 (1011153) writes "When movies shifted from videocassettes to DVD, retailers simply cleared the tapes off the shelves to make room for discs. That's not so easy now that movies appear poised to follow music onto the Internet. The shift of music online has hurt stores such as Best Buy, Wal-Mart and Circuit City, and some retailers are looking to avoid a repeat with movies. Wal-Mart has launched its own movie download service, Best Buy is said to be in talks to start one, and Blockbuster explored buying movie download company Movielink earlier this year."

Taxes, Second Life and Warcraft 441

An anonymous reader wrote in to say that there is "...a new law review article that explores the tax treatment of players in Second Life and World of Warcraft. The bottom line is that commercial activity that occurs in virtual worlds should be taxed the same as in the real world. But purely personal activity within virtual worlds should not be taxed."
