Walt Scacchi of the University of California, Irvine, and his colleagues are conducting formal studies of the informal world of open-source software development, in which a distributed community of developers produces software source code that is freely available to share, study, modify and redistribute. Theyre finding that, in many ways, open-source development can be faster, better and cheaper than the "textbook" software engineering often used in corporate settings.
In a series of reports posted online (see http://www.isr.uci.edu), Scacchi is documenting how open-source development breaks many of the software engineering rules formulated during 30 years of academic research. Far from finding that open-source development is just software engineering poorly done, Scacchi and colleagues show that it represents a new approach based on community building and other socio-technical mechanisms that might benefit traditional software engineering.
"Free and open-source software development is faster, better and cheaper in building a community and at reinforcing and institutionalizing a culture for how to develop software," said Scacchi, a senior research scientist at UC Irvines Institute for Software Research who has taught software engineering for two decades. "Were not ready to assert that open-source development is the be-all end-all for software engineering practice, but theres something going on in open-source development that is different from what we see in the textbooks."

High-precision measurement of the g-factor eleven times more precise than before / Results indicate a strong similarity between protons and antiprotons
The magnetic moment of an individual proton is inconceivably small, but can still be quantified. The basis for undertaking this measurement was laid over ten...

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.
Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....
The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
