waderoush writes "Forcing sulfur atoms into silicon using femtosecond laser pulses creates a material called 'black silicon' that is 100 to 500 times more sensitive to light than conventional silicon, in both the visible and infrared spectrums, according to SiOnyx, a venture-funded Massachusetts start-up that just emerged from stealth mode. Today's New York Times has a piece about the serendipitous discovery of black silicon inside the laboratory of Harvard physicist Eric Mazur. Meanwhile, a report in Xconomy explains how black silicon works and how SiOnyx and manufacturing partners hope to use it to build far more efficient photovoltaic cells and more sensitive detectors for medical imaging devices, surveillance satellites, and consumer digital cameras."

arbitraryaardvark writes "Reuters reports that medieval Muslims made a mega math marvel. Tile patterns on middle eastern mosques display a kind of quasicrystalline effect that was unknown in the west until rediscovered by Penrose in the 1970s. 'Quasicrystalline patterns comprise a set of interlocking units whose pattern never repeats, even when extended infinitely in all directions, and possess a special form of symmetry.' It isn't known if the mosque designers understood the math behind the patterns or not."

A reader writes "There is an interesting blog piece entitled Memoirs of a Bystander: Visual Studio.NET development on OS X w/ Parallels. The piece does a good job talking about development for different environments then the one that you are programming in. " And with the continued rise of more and more heterogeneous environments, this will become more and more common.

Aditi Tuteja writes "US Patent and Trademark Office made a new record for the number of software patents awarded in a single year. The agency has issued 893 new patents yesterday. Pushing the total to 30,232 in this year. If this is the trend, more than 40,000 software patents will be issued this year, according to the Public Patent Foundation. The previous record was set in 2004. Several major technology vendors have pledged not to enforce their patents against open source projects. IBM for instance essentially donated 500 patents to open source projects last year. Earlier this year, the US Supreme Court overthrew a prior judgement that required a judge to issue an automatic injunction if he found that a patent was being infringed."

Jeryl Kesh writes "Does Motorola's roaring success with its Linux-based 'Ming' phones in China indicate that the open-source platform is now a serious contender against Symbian and Windows Mobile in the handheld device software platform arena? The world No. 2 mobile phone maker, which debuted the Ming smartphone in March this year in China, shipped more than one million Linux-based units in China alone last quarter, according to research firm Canalys. However with Nokia refusing to adopt Linux, Symbian remains by far the top mobile device OS, according to Canalys, with a 67 percent share, well ahead of second-place Windows Mobile, with 15 percent of the market. Eirik Chambe-Eng, the co-founder of one of the most popular mobile Linux platforms, Norway-based TrollTech, has also reportedly predicted a 'revolution' in the use of open-source software on phones and handheld devices. His contention was that Linux gives handset manufacturers and OEMs (original equipment manufacturers) 'complete control,' and in turn keeps Microsoft and Symbian at bay."

robotrachel writes "According to Technology Review, the $100 laptop intended for children in the developing world will be powered in much the same way that you might start an outboard motor on a boat. The new power system will 'make the laptop much easier to power than it would be with a hand crank, in part, because the users will be able to operate the generator in a variety of ways, including holding the device (the size of two hockey pucks) in one hand and pulling the string with the other, or clamping the generator to a desk, attaching the string to one foot, and using leg power.'" There are plenty of sewing machine treadles in the world, too -- I hope someone can figure out a way to combine them with the new design.

CNet is reporting that a new proposal before Congress is attempting to increase the number of federal judges who specialize in patent litigation. From the article: "The proposal prescribes $5 million each year in federal funding over the next decade for "educational and professional development" programs for designated judges and to pay the salaries of new, specially appointed clerks with patent expertise. Under the bill, patent cases would continue to be randomly assigned to judges, but with a notable exception. Any judge who practices within a court district offering the pilot program but who chooses not to sign up for the extra training would have the option of transferring patent cases to a program participant." Techdirt also has a short writeup on why this specialization might not necessarily be a good thing.
