To get in on the deal, fill out the form at their site, and each week you will receive a newsletter containing links to download a new book. The first two books are Mistborn by Brandon Sanderson followed by Old Man's War by John Scalzi. Scalzi's site says: 'My understanding is that they don't have DRM on them. Or at least, mine isn't supposed to have, and I don't think they're planning mine to be special in that regard.'"

WirePosted tips us to a story about a group of scientists who are heading to Antarctica to study organisms that thrive in climates too extreme for most other life forms. The team will be visiting a lake that has a pH "like strong Clorox," the sediments of which "produce more methane than any other natural body of water on our planet." The scientists hope to learn about the potential for life in other unforgiving climates, such as those on Mars or the various ice-covered moons in the Solar System. Expedition leader Richard Hoover was quoted saying, "This will help us decide where to search for life on other planets and how to recognize alien life if we actually find it." We've previously discussed Antarctic microbes as they related to conditions on Mars.

ktulus cry brings news of a device that can power portable gadgets, prosthetic joints, and other mobile appliances by harvesting energy generated by walking. Researchers are working on making the device — still a moderately cumbersome 3.5 pounds — smaller while maintaining its energy harvesting capacity. CNet has a write-up with more pictures and a diagram of the device. "In the mode in which the brace is only activated while the knee is braking, the subjects required less than one watt of extra metabolic power for each watt of electricity they generated. A typical hand-crank generator, for comparison, takes an average of 6.4 watts of metabolic power to generate one watt of electricity because of inefficiencies of muscles and generators. A lighter version would be helpful to hikers or soldiers who don't have easy access to electricity. And the scientists say similar mechanisms could be built into prosthetic knees other implantable devices such as pacemakers or neurotransmitters that today require a battery, and periodic surgery to replace that battery."

snake-oil-security writes "Last fall Amit Klein found a serious weakness in the OpenBSD PRNG (pseudo-random number generator), which allows an attacker to predict the next DNS transaction ID. The same flavor of this PRNG is used in other places like the OpenBSD kernel network stack. Several other BSD operating systems copied the OpenBSD code for their own PRNG, so they're vulnerable too; Apple's Darwin-based Mac OS X and Mac OS X Server, and also NetBSD, FreeBSD, and DragonFlyBSD. All the above-mentioned vendors were contacted in November 2007. FreeBSD, NetBSD, and DragonFlyBSD committed a fix to their respective source code trees, Apple refused to provide any schedule for a fix, but OpenBSD decided not to fix it. OpenBSD's coordinator stated, in an email, that OpenBSD is completely uninterested in the problem and that the problem is completely irrelevant in the real world. This was highlighted recently when Amit Klein posted to the BugTraq list."
