NASA Goes Bargain Basement With New Satellite 150

coondoggie writes to tell us that NASA has announced a new low-cost satellite that could be ideal for those who wish to get into space quickly and (relatively) inexpensively. "The Fast, Affordable, Science and Technology SATellite (FASTSAT) is 39.5 inches in diameter — not much larger than an exercise ball. It is hexagonally shaped and clocks in at a little less than 200 Lbs. It can carry a payload up to 110 Lbs. [...] NASA said FASTSAT is just the right size for earth observing missions, space science missions, and technology demonstrations. 'We think we can do whole missions for less than $10 million instead of the traditional $100s of millions, and that includes the launch vehicle, the satellite, and the widget you want to test,' said Marshall Space Flight Center's Edward 'Sandy' Montgomery in a release."
Linux

Torvalds Explains Scheduler Decision 411

Firedog writes "There's been a lot of recent debate over why Linus Torvalds chose the new CFS process scheduler written by Ingo Molnar over the SD process scheduler written by Con Kolivas, ranging from discussing the quality of the code to favoritism and outright conspiracy theories. KernelTrap is now reporting Linus Torvalds' official stance as to why he chose the code that he did. 'People who think SD was "perfect" were simply ignoring reality,' Linus is quoted as saying. He goes on to explain that he selected the Completely Fair Scheduler because it had a maintainer who has proven himself willing and able to address problems as they are discovered. In the end, the relevance to normal Linux users is twofold: one is the question as to whether or not the Linux development model is working, and the other is the question as to whether the recently released 2.6.23 kernel will deliver an improved desktop experience."
Worms

Worm Claimed For Apple OS X 398

SkiifGeek writes "Controversy is slowly building over the development of a claimed new worm that targets OS X systems, dubbed by its inventor Rape.osx. Using a currently undisclosed vulnerability in mDNSResponder, the worm is said to give access to root as it spreads across the local network. As with a number of recent Apple-related security discoveries, the author, InfoSec Sellout, is delaying reporting the vulnerability to Apple until after completing full testing of the worm. While the worm has yet to leave a testing environment (with 1,500 OS X systems), it is bound to join the likes of Inqtana and Leap as known OS X malware."

Submission + - FreeBSD SMP greatly outperforms Linux under MySQL

shocking writes: "The recent work on moving FreeBSD to a new framework dealing with SMP issues (SMPng) has been finished, so developers have been benchmarking & profiling the code to find performance bottlenecks. After correcting a few, they found that a multithreaded MySQL benchmark performed extremely well under high load, maintaining throughput in situations where Linux throughput collapsed. The write-up is at http://people.freebsd.org/~kris/scaling/mysql.html "

Nerds Switching from Apple to Ubuntu? 957

Mindpicnic writes "The recent switch of two lifelong Mac nerds to Ubuntu hasn't escaped Tim O'Reilly's radar. He cites Jason Kottke: 'If I were Apple, I'd be worried about this. Two lifelong Mac fans are switching away from Macs to PCs running Ubuntu Linux: first it was Mark Pilgrim and now Cory Doctorow. Nerds are a small demographic, but they can also be the canary in the coal mine with stuff like this.'"
