Air Force Sets Date To Fly Mach-6 Scramjet 252

coondoggie writes "The US Air Force said it was looking to launch its 14-foot long X-51A Waverider on its first hypersonic flight test attempt May 25. The unmanned X-51A is expected to fly autonomously for five minutes, after being released from a B-52 Stratofortress off the southern coast of California. The Waverider is powered by a supersonic combustion scramjet engine, and will accelerate to about Mach 6 as it climbs to nearly 70,000 feet. Once flying, the X-51 will transmit vast amounts of data to ground stations about the flight, then splash down into the Pacific. There are no plans to recover the flight test vehicle, one of four built, the Air Force stated."

NSA Email Surveillance Pervasive and Ongoing 243

dkleinsc writes "The NY Times has a piece about work being done by Congressman Rush Holt (D-NJ) and others to curb NSA efforts to read email and Internet traffic. Here's an excerpt: 'Since April, when it was disclosed that the intercepts of some private communications of Americans went beyond legal limits in late 2008 and early 2009, several Congressional committees have been investigating. Those inquiries have led to concerns in Congress about the agency's ability to collect and read domestic e-mail messages of Americans on a widespread basis, officials said. Supporting that conclusion is the account of a former NSA analyst who, in a series of interviews, described being trained in 2005 for a program in which the agency routinely examined large volumes of Americans' e-mail messages without court warrants. Two intelligence officials confirmed that the program was still in operation.'"

Comment Re:BeOS (Score 2, Interesting) 626

It may have been an axiom, but really, what did BeOS do (or want to do) that Linux doesn't do now?

The Linux OS has been scaled to thousands of CPUs. Sure, most applications don't benefit from multi-processors, but that'd be true in BeOS, too.

I'd honestly like to know if there is some design paradigm that was lost with BeOS that isn't around today.

Should You Get Paid While Your Computer Boots? 794

An anonymous reader notes a posting up at a law blog with the provocative title Does Your Boss Have to Pay You While You Wait for Vista to Boot Up?. (Provocative because Vista doesn't boot more slowly than anything else, necessarily, as one commenter points out.) The National Law Journal article behind the post requires subscription. Quoting: "Lawyers are noting a new type of lawsuit, in which employees are suing over time spent booting [up] their computers. ... During the past year, several companies, including AT&T Inc., UnitedHealth Group Inc. and Cigna Corp., have been hit with lawsuits in which employees claimed that they were not paid for the 15- to 30-minute task of booting their computers at the start of each day and logging out at the end. Add those minutes up over a week, and hourly employees are losing some serious pay, argues plaintiffs' lawyer Mark Thierman, a Las Vegas solo practitioner who has filed a handful of computer-booting lawsuits in recent years. ... [A] management-side attorney... who is defending a half-dozen employers in computer-booting lawsuits... believes that, in most cases, computer booting does not warrant being called work."

Intel Shows Data Centers Can Get By (Mostly) With Little AC 287

Ted Samson IW writes "InfoWorld reports on an experiment in air economization, aka 'free cooling,' conducted by Intel. For 10 months, the chipmaker had 500 production servers, working at 90 percent utilization, cooled almost exclusively by outside air at a facility in New Mexico. Only when the temperature exceeded 90 degrees Fahrenheit did they crank on some artificial air conditioning. Intel did very little to address air-born contaminants and dust, and nothing at all to deal with fluctuating humidity. The result: a slightly higher failure rate — around 0.6 percent more — among the air-cooled servers compared to those in the company's main datacenter — and a potential savings of $2.87 million per year in a 10MW datacenter using free cooling over traditional cooling."

Submission + - Making NetBSD Multiboot-Compatible

jmmv writes: "The Multiboot Specification defines a protocol between boot loaders and operating systems' kernels with the basic aim to allow any compliant boot loader to launch any compliant OS. This simplifies the boot loader's tasks by reducing the amount of knowledge it must have of foreign OSes and, as a side effect, it also removes the burden of writing a custom boot loader for each OS. A while ago I modified the NetBSD's kernel to support this specification, which means that the upcoming 4.0 release will be easier to boot on any dual-boot system with Linux installed (assuming it uses GRUB). I've written an article, titled Making NetBSD Multiboot-Compatible, that provides an introduction to The Multiboot Specification and outlines the steps I took to adapt the NetBSD's kernel to follow it. This can give you enough interest and clues to modify your favourite operating system to also support this protocol."

Paul Graham on Patents 302

volts writes "The always interesting Paul Graham has a new essay, 'Are Software Patents Evil?'. "A few weeks ago I found to my surprise that I'd been granted four patents. This was all the more surprising because I'd only applied for three...""
