Comment Re:Garbage collected virtual machines! (Score 5, Insightful) 341

Most of what they've done seems to be rearchitecting, not getting a simple speed boost from using an unmanaged language. They're bypassing the OS to get more locality and cache retention. Those problems would not be addressed by merely rewriting in C++.

For one, they've replaced the OS network stack with an in-process one, where each thread gets its own NIC queue so they can have "zero-copy, zero-lock, and zero-context-switch[es]"

They're also keeping more data in memory and eschewing relying on the the OS file cache. It seems like they're taking every opportunity to use the in memory representation to avoid using sstables. They try harder than Cassandra to update instead of invalidate that cache on writes.

Submission + - US Senate Declares War On Citizens ( 4

iONiUM writes: "In a stunning move, the US senate passed a bill that effectively ends the Bill of Rights in America. From the article, "This bill, passed late last night in a 93-7 vote, declares the entire USA to be a ”battleground” upon which U.S. military forces can operate with impunity, overriding Posse Comitatus and granting the military the unchecked power to arrest, detain, interrogate and even assassinate U.S. citizens with impunity."
Wired magazine is also reporting this story, with similar disgust: "Here’s the best thing that can be said about the new detention powers the Senate has tucked into next year’s defense bill: They don’t force the military to detain American citizens indefinitely without a trial. They just let the military do that."
Good luck Americans. You're gonna need it."


AMD Demos Llano Fusion APU, Radeon 6800 Series 116

MojoKid writes "At a press event for the impending launch of AMD's new Radeon HD 6870 and HD 6850 series graphics cards, the company took the opportunity to provide an early look at the first, fully functional samples of their upcoming 'Llano' processor, or APU (Applications Processer Unit). For those unfamiliar with Llano, it's 32nm 'Fusion' product that integrates CPU, GPU, and Northbridge functions on a single die. The chip is a low-power derivative of the company's current Phenom II architecture fused with a GPU that will target a wide range of operating environments at speeds of 3GHz or higher. Test systems showed the integrated GPU had no trouble running Alien vs. Predator at a moderate resolution with DirectX 11 features enabled. In terms of the Radeon 6800 series, board shots have been unveiled today, as well as scenes from AMD's upcoming tech demo, Mecha Warrior, showcasing the new graphics technology and advanced effects from the open source Bullet Physics library."
