The 'Linux Inside' Stigma 366

Posted by Soulskill from the someday-they'll-even-come-up-with-a-linux-phone dept.
New submitter dtschmitz highlights the success of the Google Chromebook to underscore what, in his view, is a serious Linux brand image problem. "It's remarkable how Google doesn't mention the word Linux anywhere in their marketing of the Google Chromebook. I mean, it's running the Linux Kernel, so shouldn't it be Google Linux instead of ChromeOS? Why did Google carefully avoid references to Linux? It's all a very carefully crafted, well executed plan of elegant branding and image making. ... The profile of this user is that of someone who really doesn't care anything about the technical underpinnings of a device. They are not sophisticated technophiles by any means. They have a set number of things which they wish to do--recreational surfing, banking, email, an occasional letter, not complicated. ... Google didn't mention Linux because they know it will scare buyers away. That's unfortunate, but true. And we need to come to terms with that fact and work towards improving the 'Linux Inside' brand image.

New LLVM Debugger Subproject Already Faster Than GDB 174

Posted by timothy from the pop-will-eat-itself dept.
kthreadd writes "The LLVM project is now working on a debugger called LLDB that's already faster than GDB and could be a possible alternative in the future for C, C++, and Objective-C developers. With the ongoing success of Clang and other LLVM subprojects, are the days of GNU as the mainstream free and open development toolchain passé?" LLVM stands for Low Level Virtual Machine; Wikipedia as usual has a good explanation of the parent project.

Planned Nuclear Reactors Will Destroy Atomic Waste 344

Posted by Soulskill from the but-where-will-we-get-our-superheroes dept.
separsons writes "A group of French scientists are developing a nuclear reactor that burns up actinides — highly radioactive uranium isotopes. They estimate that 'the volume of high-level nuclear waste produced by all of France’s 58 reactors over the past 40 years could fit in one Olympic-size swimming pool.' And they're not the only ones trying to eliminate atomic waste: Researchers at the University of Texas in Austin are working on a fusion-fission reactor. The reactor destroys waste by firing streams of neutrons at it, reducing atomic waste by up to 99 percent!"

Study Shows People In Power Make Better Liars 265

Posted by Soulskill from the practice-makes-perfect dept.
oDDmON oUT writes "MSNBC is reporting that a Columbia Business School study shows those who hold power over others make better liars. According to one of the study's coauthors, 'It just doesn't hurt them as much to do it.' For the average liar, she said, the act of lying elicits negative emotions, physiological stress and the fear of getting caught in a lie. As a result, she added, liars will often send out cues that they are lying by doing things like fidgeting in a chair or changing the rate of their speech. But for the powerful, the impact is very different: 'Power, it seems, enhances the same emotional, cognitive, and physiological systems that lie-telling depletes. People with power enjoy positive emotions, increases in cognitive function, and physiological resilience such as lower levels of the stress hormone cortisol. Thus, holding power over others might make it easier for people to tell lies.'"

Piezo Crystals Harness Sound To Generate Hydrogen 187

Posted by timothy from the what's-shakin'? dept.
MikeChino writes "Scientists at the University of Wisconsin-Madison have discovered that a mix of zinc oxide crystals, water, and noise pollution can efficiently produce hydrogen without the need for a dirty catalyst like oil. To generate the clean hydrogen, researchers produced a new type of zinc oxide crystals that absorb vibrations when placed in water. The vibrations cause the crystals to develop areas with strong positive and negative charges — a reaction that rips the surrounding water molecules and releases hydrogen and oxygen. The mechanism, dubbed the piezoelectrochemical effect, converts 18% of energy from vibrations into hydrogen gas (compared to 10% from conventional piezoelectric materials), and since any vibration can produce the effect, the system could one day be used to generate power from anything that produces noise — cars whizzing by on the highway, crashing waves in the ocean, or planes landing at an airport."

Comment In Search of Clusters (Score 3) 106

by Zootlewurdle (#1490782) Attached to: Choosing the Right Cluster System
I would whole heartedly recommend that anybody interested in clustering should read Greg Pfisters "In Search of Clusters" published by Prentice Hall - ISBN 0-13-899709-8. It is the seminal work in this area.

Other good resources include:
- IEEE Task Force on Cluster Computing
http://www.dgs.monash.edu.au/~rajkumar/tfcc/index. html
- Linux-HA http://linux-ha.org/
- some general links
http://www.tu-chemnitz.de/informatik/RA/cchp/index .html

There are more clustering products out than you can shake a stick at, and everybody seems have a different take what they mean by a cluster.

Does anyone have any information on what the Linux Cluster Cabal are up to ?

Probably the best thought out cluster solutions are OpenVMS Clusters and UnixWare NonStop Clusters.
