sheepweevil writes "IBM just released Milepost GCC, 'the world's first open source machine learning compiler.' The compiler analyses the software and determines which code optimizations will be most effective during compilation using machine learning techniques. Experiments carried out with the compiler achieved an average 18% performance improvement. The compiler is expected to significantly reduce time-to-market of new software, because lengthy manual optimization can now be carried out by the compiler. A new code tuning website has been launched to coincide with the compiler release. The website features collaborative performance tuning and sharing of interesting optimization cases."

meketrefi writes "It's been quite a while since I got interested in the idea of using html (instead of .doc. or .odf) as a standard for saving documents — including the more official ones like academic papers. The problem is using HTML to create pages with a stable size that would deal with bibliographical references, page breaks, different printers, etc. Does anyone think it is possible to develop a decent tag like 'div,' but called 'page,' specially for this? Something that would make no use of CSS? Maybe something with attributes as follows: {page size="A4" borders="2.5cm,2.5cm,2cm,2cm" page_numbering="bottomleft,startfrom0"} — You get the idea... { /page} I guess you would not be able to tell when the page would be full, so the browser would have to be in charge of breaking the content into multiple pages when needed. Bibliographical references would probably need a special tag as well, positioned inside the tag ..." Is this such a crazy idea? What would you advise?

SailorSpork sends in a BBC report that "China is delaying a controversial plan requiring all new computers sold in the country to be equipped with an Internet filtering software, state media says. The filter, called Green Dam Youth Escort, was to have been required from Wednesday, but the ministry of industry said computer makers needed more time." The submitter adds: "Except of course for Sony, who as reported earlier lacked the moral fiber to hold off installing the spyware, which reportedly is ridden with security holes and uses stolen code. Sony actually managed to ship ahead of the schedule."

Sue Williams has been awarded a £20,000 grant by the Arts Council of Wales, to "explore cultural attitudes towards female buttocks." Sue plans to examine racial attitudes towards bottoms in Europe and Africa and create plaster casts of women's behinds to try to understand their place in contemporary culture. And here I've been studying the issue all these years for free like a sucker!

selven was one of several readers to send in the news that Bernie Madoff was sentenced to 150 years in prison. "Bernard Madoff's victims gasped and cheered when he was sentenced to 150 years in prison, but they walked away knowing little more about how he carried out the biggest robbery in Wall Street history. In one of the most dramatic courtroom conclusions to a corporate fraud case, the 71-year-old swindler was unemotional as he was berated by distraught investors during the 90-minute proceeding. Many former clients had hoped he would shed more light on his crime and explain why he victimized so many for so long. But he did not. Madoff called his crime 'an error of judgment' and his 'failure,' reiterating previous statements that he alone was responsible for the $65 billion investment fraud. His victims said they did not hear much new from Madoff in his five-minute statement. They also said they did not believe anything he said. As he handed down the maximum penalty allowed, US District Judge Denny Chin... [said], 'I simply do not get the sense that Mr. Madoff has done all that he could or told all that he knows.'"

KentuckyFC writes "The density of magnetic memory depends on the size of the magnetic domains used to store bits. The current state-of-the-art uses cobalt-based grains some 8nm across, each containing about 50,000 atoms. Materials scientists think they can shrink the grains to 15,000 atoms but any smaller than that and the crystal structure of the grains is lost. That's a problem because the cobalt has to be arranged in a hexagonal close packing structure to ensure the stability of its magnetic field. Otherwise the field can spontaneously reverse and the data is lost. Now a group of German physicists say they can trick a pair of cobalt atoms into thinking they are in a hexagonal close packing structure by bonding them to a hexagonal carbon ring such as graphene or benzene. That's handy because the magnetic field associated with cobalt dimers is calculated to be far more stable than the field in a cobalt grain. And graphene and benzene rings are only 0.5 nm across, a size that could allow an increase in memory density of three orders of magnitude."

Hugh Pickens writes "Findings of a new study show that underweight people and those who are extremely obese die earlier than people of normal weight — but those who are only a little overweight actually live longer than people of normal weight. 'It's not surprising that extreme underweight and extreme obesity increase the risk of dying, but it is surprising that carrying a little extra weight may give people a longevity advantage,' said one of the coauthors of the study. 'It may be that a few extra pounds actually protect older people as their health declines, but that doesn't mean that people in the normal weight range should try to put on a few pounds.' The study examined the relationship between body mass index and death among 11,326 adults in Canada over a 12-year period. The study showed that underweight people were 70 percent more likely than people of normal weight to die, and extremely obese people were 36 percent more likely to die. But overweight individuals defined as a body mass index of 25 to 29.9 were 17 percent less likely to die than people of a normal weight defined as a BMI of 18.5 to 24.9. The relative risk for obese people was nearly the same as for people of normal weight. The authors controlled for factors such as age, sex, physical activity, and smoking. 'Overweight may not be the problem we thought it was,' said Dr. David H. Feeny, a senior investigator at Kaiser Permanente Center for Health Research. 'Overweight was protective.'"
