An anonymous reader writes "An unconventional article on the development of the WebKit project was just posted to the arXiv. Those guys data-mined the WebKit source-code change-log with Social Network Analysis. They claim that even if Apple and Samsung fight each other with patent wars in the courts, they still collaborate in the WebKit community. The report provides a different perspective from the Bitergia WebKit analytics. Some interesting polemics regarding Apple, Google and Nokia participation in the WebKit project are also highlighted in the paper. There are some nice figures capturing collaboration and rivalry in the WebKit community."

porkpickle tips us to a BBC article on the quasar OJ287, a binary object containing largest black hole yet discovered, weighing in at 18 billion times the mass of Sol. Researchers were able to estimate its mass due to the presence of a smaller black hole in orbit around it. When the smaller companion's orbit intersects OJ287's accretion disk, once every 12 years, it triggers a burst of radiation that was detected by the Spitzer Space Telescope. More detail and a diagram are available on the Turku University site.

We wondered if it would happen, but Jani Halme just wrote in and told me it did. The GNUStep project has released v0.5 of their very exciting package. It's great to see code froming from a source that obviously has a lot of good stuff going for it. Snag the program from the web site or gnu.org.
