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."

AI implications: Engineer's model lays groundwork for machine-learning device

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
