FreeBSD 7.0 Bests Linux In SMP Performance 288

cecom writes "After major improvements in SMP support in FreeBSD 7.0, benchmarks show it performing 15% better than the latest Linux kernels (PDF, see slides 17 to 19) on 8 CPUs under PostgreSQL and MySQL. While a couple of benchmarks are not conclusive evidence, it can be assumed that FreeBSD will once again be a serious performance contender. Some posters on LWN have noted that the level of Linux performance could be related to the Completely Fair Scheduler, which was merged into the 2.6.23 Linux kernel." Update: 03/06 21:32 GMT by KD : An anonymous reader sent in word that Linux kernel developer Nick Piggin reran the benchmark today and came to a different conclusion: In his benchmark Linux was faster than FreeBSD.

What's New in OpenBSD 4.2? 203

blackbearnh writes "OpenBSD 4.2 was released today, and has a host of new features. O'Reilly's ONLamp site has a pretty thorough overview of the release. 'Even though security is still there, this release comes with some amazing performance improvements: basic benchmarks showed PF being twice as fast, a rewrite of the TLB shootdown code for i386 and amd64 cut the time to do a full package build by 20 percent (mostly because all the forks in configure scripts have become much cheaper), and the improved frequency scaling on MP systems can help save nearly 20 percent of battery power. And then the new features: FFS2, support for the Advanced Host Controller Interface, IP balancing in CARP, layer 7 manipulation with hoststated, Xenocara, and more!'"

KDE Readies KOffice 2.0 As OpenOffice Competitor 337

Da Massive writes in with a link to a story on KOffice 2.0, the next generation of the KDE office suite due sometime next year. In an interview with KDE spokesman Sebastian Kugler, Computerworld reports that KOffice 2.0 will be leaner, faster, and enjoy a cleaner code base than OpenOffice. It will also feature more applications, including an Access-like database creator, a flowcharter, and an image manipulation tool. KOffice is not yet fully compatible with ODF but the claim is that 2.0 will be.

Submission + - Pluto Probe Makes Discoveries at Jupiter (jhuapl.edu)

Riding with Robots writes: No, it's not an accident due to a metric-to-English-units error. In February, the New Horizons probe passed through the Jupiter system on its way to Pluto, and we saw some spectacular pictures. Now, the science teams have published detailed scientific results, along with new images and movies. an overview is now online. The probe's instruments saw clouds form from ammonia welling up from Jupiter's lower atmosphere, and heat-induced lighting strikes in the polar regions, and fresh eruptions on the volcanic moon Io. New Horizons also captured the clearest images ever of the tenuous Jovian ring system, where scientists spotted clumps of debris that may indicate a recent impact inside the rings, or some more exotic phenomenon.

Defending Games For Adults on National Television 134

N'Gai Croal, at the Newsweek blog LevelUp, had the chance to talk about the Manhunt 2 ban/re-rating fiasco on the CNN program American Morning. It's an interesting discussion of the issue, and it sounds like for the most part he got a fair shake; this wasn't yet another 'ambush the games journalist'-style cable program. The one thing N'Gai tried to make clear - and may have gotten lost in the shuffle - was that this title categorically is not for kids. "We bring this up not because there's anything sinister at work, but rather because [co-anchor Kiran Chetry] isn't alone in her bedrock assumption that all videogames are primarily aimed at 'kids.' After all, had we gone on the show to discuss Ang Lee's NC-17-rated erotic thriller 'Lust, Caution,' or the upcoming horror movie '30 Days of Night,' we doubt that we'd have been asked 'Would you let your kids watch it?' It would have been assumed that those movies, like certain TV shows, books or plays, are not intended for children. Yet videogames often don't get the same recognition."

Theo de Raadt On Relicensing BSD Code 613

iBSD writes "KernelTrap has an interesting article in which Theo de Raadt discusses the legal implications of the recent relicensing of OpenBSD's BSD-licensed Atheros driver under the GPL. De Raadt says, 'it has been like pulling teeth since (most) Linux wireless guys and the SFLC do not wish to admit fault. I think that the Linux wireless guys should really think hard about this problem, how they look, and the legal risks they place upon the future of their source code bodies.' He stressed that the theory that BSD code can simply be relicensed to the GPL without making significant changes to the code is false, adding, 'in their zeal to get the code under their own license, some of these Linux wireless developers have broken copyright law repeatedly. But to even get to the point where they broke copyright law, they had to bypass a whole series of ethical considerations too.'"

OpenBSD Foundation Announced 151

OpenBDSfan writes "KernelTrap is reporting on the creation of the OpenBSD Foundation, a Canadian not-for-profit corporation intended to support OpenBSD and related projects, including OpenSSH, OpenBGPD, OpenNTPD, and OpenCVS. The announcement explains, "the OpenBSD Foundation will initially concentrate on facilitating larger donations of equipment, funds, documentation and resources. Small scale donations should continue to be submitted through the existing mechanisms.""

Copyright Law Used to Shut Down Site 206

driptray writes "The Sydney Morning Herald reports that an Australian mining industry group has used copyright laws to close a website that parodied a coal industry ad campaign. A group known as Rising Tide created the website using the slogan "Rising sea levels: brought to you by mining" in response to the mining industry's slogan of "Life: brought to you by mining". The mining industry claimed that the "content and layout" of the parody site infringed copyright, but when Rising Tide removed the copyrighted photos and changed the layout, the mining industry still lodged a complaint. Is this a misuse of copyright law in order to stifle dissent?"

The patent system is not broken, just not perfect. That is the viewpoint of Jon Dudas, the Under Secretary of Commerce for Intellectual Property and Director of the United States Patent and Trademark Office (USPTO).

Google Ads Are a Free Speech Issue 148

WebHostingGuy writes "A US Federal Court recently ruled that ads displayed by search engines are protected as free speech. In the case at issue, Yahoo!, Google, and Microsoft were sued by an individual demanding under the 14th Amendment that the search engines display his advertisements concerning fraud in North Carolina. The Court flatly stated that the search engines were exercising their First Amendment right of free speech in deciding what ads they want to display."

British Government Slashes Scientific Research 168

asobala writes "The British Government has slashed the funding of scientific Research Councils by £68 million. The Research Councils most affected by this include the Engineering and Physical Sciences Research Council, which has been hit by a £29 million reduction in funding, and the Medical Research Council, which is seeing a £10.7 million reduction in funding. The response of the BBSRC biological research council announces that the council will have to cut 20 new grants and reduce expenditure on new equipment."

Surveillance Cameras Get Smarter 186

kog777 writes to mention that the IB Times is taking a look at where surveillance camera technology is headed. Soon researchers tell us that cameras will be available that not only record, but are able to interpret what they see. "The advancements have already been put to work. For example, cameras in Chicago and Washington can detect gunshots and alert police. Baltimore installed cameras that can play a recorded message and snap pictures of graffiti sprayers or illegal dumpers. In the commercial market, the gaming industry uses camera systems that can detect facial features, according to Bordes. Casinos use their vast banks of security cameras to hunt cheating gamblers who have been flagged before."
