coondoggie writes to tell us that NASA and JAXA (the Japan Aerospace Exploration Agency) have announced a partnership to study the sonic boom. Hoping to find the key to the next generation of supersonic aircraft, the research will include a look at JAXA's "Silent Supersonic Technology Demonstration Program." "The change in air pressure associated with a sonic boom is only a few pounds per square foot -- about the same pressure change experienced riding an elevator down two or three floors. It is the rate of change, the sudden onset of the pressure change, that makes the sonic boom audible, NASA said. All aircraft generate two cones, at the nose and at the tail. They are usually of similar strength and the time interval between the two as they reach the ground is primarily dependent on the size of the aircraft and its altitude. Most people on the ground cannot distinguish between the two and they are usually heard as a single sonic boom. Sonic booms created by vehicles the size and mass of the space shuttle are very distinguishable and two distinct booms are easily heard."

Techdirt called our attention to an interesting video of patent attorney Stephan Kinsella's presentation on "Rethinking Intellectual Property Completely". It's a long presentation, but well worth the time to watch. There is also an ongoing series of posts discussing intellectual property rights on Techdirt for additional reading.

schliz writes to mention that in a recent interview with ITNews researcher John Shalf explained the purpose and some of the technical details of the newly-announced "iPod supercomputer". "Microprocessors from portable electronics like iPods could yield low-cost, low-power supercomputers for specialized scientific applications, according to computer scientist John Shalf. Along with a research team from the U.S. Department of Energy's Lawrence Berkeley National Laboratory, Shalf is designing a supercomputer based on low-power embedded microprocessors, which has the sole purpose of improving global climate change predictions."

Manfre writes "On his birthday, John Resig (creator of jQuery) has given a present to developers by releasing Processing.js. This is a Javascript port of the Processing Visualization Language and a first step towards Javascript being a rival to Flash for online graphics content. His blog post contains an excellent writeup with many demos."

sciurus0 writes "As the open source version control system Subversion nears its 1.5 release, one of its developers asks, what is the project's future? On the one hand, the number of public Subversion DAV servers is still growing quadratically. On the other hand, open source developers are increasingly switching to distributed version control systems like Git and Mercurial. Is there still a need for centralized version control in some environments, or is Linus Torvalds right that all who use it are 'ugly and stupid'?" The comments on the blog post have high S/N.

yo_cruyff notes a Computerworld article on Google's recent annual shareholder meeting, which was dominated by argument over the company's human rights policies. Google's shareholders, on advice from their board, have voted down two proposals on Thursday that would have compelled Google to change its policies. "Google [has been] coming under fire for operating a version of its search engine that complies with China's censorship rules. Google argues that it's better for it to have a presence in the country and to offer people some information, rather than for it not to be active in China at all... [S]hareholders and rights groups including Amnesty International... continue to push Google to improve its policies in countries known for human rights abuses and limits on freedom of speech... Sergey Brin, cofounder and president of technology for Google, abstained from voting on either of the proposals. 'I agreed with the spirit of these proposals,' Brin said. But he said he didn't fully support them as they were written, and so did not want to vote for them."

ozmanjusri writes "According to Information Week, within hours of its wide availability Windows XP SP3 had drawn hundreds of complaints from users who claim the update is wreaking havoc on their computers. One user said in a Microsoft newsgroup: 'I downloaded and installed [the SP3] package for IT Professionals and Developers on one of my computers. Now I can't get the computer to boot. I don't think Microsoft should have made this a critical update.' Other sites including IT Wire are also reporting problems, which include include random reboots or the inability to boot at all." Note that XP3 won't install on systems running beta IE8; and after a successful SP3 install users will no longer be able to downgrade from IE7 to IE6.

An anonymous reader writes "The x86 instruction set may be ancient, in technology terms, but that doesn't mean it's not exciting or innovative. In fact the future of x86 is looking brighter than it has in years. Geek.com has an article pointing out how at 30 years old x86 is still a moving force in technological advancement and, despite calls for change and numerous alternatives, it will still be the technology that gets us where we want to go. Quoting: 'As far as the world of the x86 goes, the future is very bright. There are so many new markets that 45nm products enable. Intel has really nailed the future with this goal. And in the future when they produce 32nm, and underclock their existing processors to allow the extremely low power requirements of cell phones and other items, then the x86 will be the power-house for our home computers, our notebooks, our cell phones, our MIDs and other unrealized devices today.'"

Facebook has reached an agreement with the attorneys general of 49 states and the District of Columbia to develop and enhance controls to protect minors from inappropriate content. This follows a similar commitment from MySpace several months ago. The lone holdout in each case was Texas. News.com notes: "In the deal, the social network has agreed to develop age verification technology, send warning messages when an under-18 user may be giving personal information to an unknown adult, restrict the ability for people to change their ages on the site, and keep abreast of inappropriate content and harassment on the site. While the agreement is with U.S. state authorities, Kelly said that the tools deployed will apply to Facebook's international users as well. More than half of the site's 70 million users are outside the U.S."

praps writes "Having tasted blood with its victory over TorrentSpy, the MPAA is now stepping up its attack on The Pirate Bay. The association is claiming damages of over $15 million, based on The Pirate Bay's distribution of four films and a TV series — Harry Potter, The Pink Panther, Syriana, Walk the Line and the first season of Prison Break. The Swedish court is unlikely to be as generous as the one in California, although the four Pirate Bay founders are already facing charges of being accessories to breaking copyright law." TorrentSpy, in the meantime, has declined to pay the settlement awarded to the MPAA on Wednesday. In addition to appealing the decision, they have filed for bankruptcy.

I Don't Believe in Imaginary Property writes "The Los Angeles County Board of Supervisors has declared that copyright infringement 'substantially interferes with the interest of the public in the quality of life and community peace, lawful commerce in the county, property values, and is detrimental to the public health, safety, and welfare of the county's citizens, its businesses and its visitors.' You might laugh, but that means they can close up a property for up to one year for violations of the anti-infringement ordinance [PDF] and the owner can be fined $1,000 for each infringing work produced on site. Not to mention the penalties in the PRO-IP Act, which just sailed through the House."
