Submission + - OpenSolaris or FreeBSD?

Norsefire writes: I am in quite a predicament. I decided a while back to branch out and use a new operating system (currently running Debian), after a bit of searching (trying Gentoo, Gobo and Arch along the way) I decided to use something that isn't Linux. Long story, short: I narrowed the choice down to OpenSolaris and FreeBSD but now I'm stuck. OpenSolaris is commercially backed by Sun, has nice enterprisey tools in the default install and best of all, a mature implementation of ZFS. FreeBSD is backed by a foundation, has a minimal default install and a rather new (but recently improved in the 8.0 release) implementation of ZFS, however it offers the Ports Collection (I quite like the performance boost from compiling from source, no matter how small it might be) and a bigger community than OpenSolaris. That is just a very minimal mention of the differences, I would be interested to see what the Slashdot community thinks of these two operating systems.

Submission + - Penny-Sized Nuclear Batteries Developed 1

Nuclear batteries that produce energy from the decay of radioisotopes are an attractive proposition for many applications because the isotopes that power them can provide a useful amount of current for hundreds of years at power densities a million times as high as standard batteries. Although nuclear batteries have been used for military and aerospace applications for years their large size has limited their general usage but now a research team at the University of Missouri team has developed a nuclear battery the size of a penny that could be used to power micro- and nano-electromechanical systems. The researchers' innovation is not only in the battery's size, but also that the batteries use a liquid semiconductor rather than a solid semiconductor. "The critical part of using a radioactive battery is that when you harvest the energy, part of the radiation energy can damage the lattice structure of the solid semiconductor," says Jae Wan Kwon. "By using a liquid semiconductor, we believe we can minimize that problem." The batteries are safe under normal operating conditions. "People hear the word 'nuclear' and think of something very dangerous," says Kwon. "However, nuclear power sources have already been safely powering a variety of devices, such as pacemakers, space satellites and underwater systems."

UK Government Abandons Piracy Legislation 155

arcticstoat writes "Following last year's reports of a scheme to 'ban' pirates from the Internet via ISPs in the UK, it looks as though the UK government has now decided to back down on the plan, saying that it hopes it won't have to apply 'the heavy hand of legislation'. The UK's Intellectual Property Minister, David Lammy, said that 'I'm not sure it's actually going to be possible,' as a result of the complexities of enforcing such legislation. Lammy also revealed that he had a different opinion on file sharers than many people in the music industry. He pointed out that there's a big difference between organized counterfeiting gangs and 'younger people not quite buying into the system'. He added that 'we can't have a system where we're talking about arresting teenagers in their bedrooms. People can rent a room in an hotel and leave with a bar of soap — there's a big difference between leaving with a bar of soap and leaving with the television.'"

Technocrat.net Shut Down 326

twitter writes "Bruce Perens has pulled the plug on Technocrat.net. 'The technocrat.net public discussion site is shut down. This has happened because the site never achieved the ability to financially sustain its editorial staff and system expenses with its revenues. When it became evident that Technocrat was un-viable as a business, I found that I did not wish to keep supporting the site as a hobby. Certain elements of the community that developed here, unfortunately, creep me out. At the end I faced the decision of asking for donations to keep the site running, or letting it die, and it became clear to me that I'd feel better if it would just die. I am very busy building a new software business, with some great new (and yet unannounced) Open Source software in development. I must focus on that for now. Best holiday wishes to you all.'"

Carbon Dioxide and Water Found On Exoplanet 151

Off the Rails writes "The BBC reports that evidence has been found for both water vapour and carbon dioxide on a planet 63 light years away. The planet is a 'hot Jupiter' with a surface temperature of 1173K and an orbital period of just 53 hours. The gases were found spectroscopically once its orbit had been deduced from observation. NASA hailed the news as proof that Kepler will be able to do its job of finding planets capable of supporting life." Wikipedia also has an entry on the planet, dubbed HD 189733b.

Low-Income Users Latch On To iPhone 422

narramissic writes "The iPhone crowd is still dominated by affluent males between the ages of 18 and 35, but in a series of surveys ending in August, ComScore found that iPhone purchases grew fastest among people with annual household incomes between $25,000 and $50,000. The growth rate in this group was 48 percent, compared with just 16 percent among people with incomes above $100,000. And the down economy isn't going to turn this trend around, says ComScore Mobile analyst Jen Wu. 'I don't see there's going to be much of a slowdown, just because wireless devices are so much more of a necessity than they used to be,' Wu said." In other iPhone news, an anonymous reader points out a NYTimes story about the rise in car-related applications and uses for the iPhone, which points out that programmers are just beginning to "appreciate just what can be done with an iPhone and other advanced cellphones that know where they are and just how quickly they are going someplace else." Another iPhone story mentions that "Opera's engineers have developed a version of Opera Mini that can run on an Apple iPhone, but Apple won't let the company release it because it competes with Apple's own Safari browser."
