Changing the output frequency of a giant high energy chemical laser is extremely tricky. Frequency doubling demands a very pure coherence to get good efficiency, and even then "good" in this context means above 50% power converted to the new frequency. With a weapons laser, you're going to have a hell of a cooling problem in the converting medium. Then again, if reflective anti-laser coatings become common, it shouldn't be too difficult to add on a free electron laser system to burn off the mirror layer before the main beam strikes. A free electron laser can change operating frequencies trivially, just by adjusting its internal magnetic field.

It's a chemical laser but in solid, not gaseous, form. Put simply, in deference to you, Kent, it's like lasing a stick of dynamite. As soon as we apply a field, we couple to a state, it is radiatively coupled to the ground state. I figure we can extract at least ten to the twenty-first photons per cubic centimeter which will give one kilojoule per cubic centimeter at 600 nanometers, or, one megajoule per liter.

Anti-Globalism
Anti-Globalism writes "To discuss the cheap-talk challenge, I imagine bringing together a panel in openDemocracy's office whose members have a modest track-record on debate: Plato, Jean-Jacques Rousseau, John Stuart Mill, Hannah Arendt and Jürgen Habermas. I will use "Cmdr Taco" as the alias of web-savvy pragmatism in the discussion. Cmdr Taco founded the techno-libertarian community and forum, Slashdot in September 1997. Slashdot is still the best example of a web-made community, so I feel that Cmdr Taco should be the mouthpiece for the web in this imaginary conversation. But almost everything I have Cmdr Taco say here is made up by me. (Plato, like Cmdr Taco, also uses an alias. Plato was actually the name of an Athenian champion wrestler in the games of 406 bce. Adopting the name would be like posting in the openDemocracy forums calling myself Mohammed Ali.)

When this new, malicious, DNS server is active, it hijacks some web requests, leading users to phishing web sites (for sites such as Ebay, PayPal and some banks), or simply to web pages displaying ads for other pornographic web sites.""

Submitted by graviplana
graviplana (1160181) writes "From the Article: "In an often heated exchange, Torvalds accused security programmers of being too concerned with theoretical problems and not enough with practical applications. Smack uses Linux Security Modules (LSM) which some researchers believe could be used to aid attacks on systems using the code. The researchers would prefer to see Security-Enhanced Linux as the option of choice. "If LSM remains, security will never be a first class citizen of the kernel, " said Linux developer James Morris. But this set Torvalds off on a rant about the impossibility of satisfying the demands of security researchers. "You security people are insane. I am tired of this 'only my version is correct' crap," he wrote.""

From the Article: "The world's first true invisibility cloak — a device able to hide an object in the visible spectrum — has been created by physicists in the US. ... Their breakthrough comes just a year after US and British physicists created an invisibility cloak that worked in the microwave region of the electromagnetic spectrum. At that time, a visible light cloak was thought to be years away because of the much shorter wavelengths produced in the visible spectrum.""

MojoKid writes "When DirectX 10 was first introduced to the market by graphics manufacturers and subsequently supported by Windows Vista, it was generally understood that adoption by game developers was going to be more of a slow migration than a quick flip of a switch. That said, nearly a year later, the question is how far have we come? This in-depth HotHardware article showcases many of the most popular DX10-capable game engines, like Bioshock, World In Conflict, Call of Juarez, Lost Planet, and Company of Heroes, and features current image quality comparisons versus DX9 modes with each. The article also details performance levels across many of the more popular graphics cards, from both the mid-range and high-end. You be the judge. Are we there yet?"
