Neural networks to predict the mass of planets in formation

An article published in the journal “Astronomy and Astrophysics” shows an example of the use of a neural network and a deep learning algorithm to reduce the time to create simulations of star systems formation obtaining even better results. Yann Alibert of NCCR PlanetS and of the Swiss University of Bern and Julia Venturini of the International Space Science Institute (ISSI) of Bern and a PlanetS collaborator developed this new system that predicts the mass of a planet starting from the conditions in which it formed with a excellent accuracy and a much higher speed than models based on differential equations.

A California district court has approved a settlement between the PC manufacturer Lenovo and a group of customers to wrap up a class action that began after an adware that caused a serious vulnerability had been discovered on various Lenovo laptop models. The laptop maker will pay a total of $7.3 million while Superfish, the producer of the adware, will pay another million dollars to close the litigation for good.

IBM and Red Hat announced that they have reached an agreement with which IBM will acquire all Red Hat’s shares, whose value closed last Friday at $116.68, for $190 per share paid in cash for a total value of about $34 billions. Red Hat will become part of IBM’s Hybrid Cloud division while its CEO Jim Whitehurst will join IBM’s senior management reporting to CEO Ginni Rometty. This acquisition is oriented above all to make IBM a giant in the field of cloud services.

MS-DOS 6

Microsoft has announced the release of the sources of versions 1.25 and 2.0 of its MS-DOS operating system, which were made available on the GitHub website, under the MIT free / open source license. In 2014 the same sources were released to the Computer History Museum but with a restrictive license, for historical reasons. The released versions are very old and Microsoft will not accept pull requests to modify them sent through the GitHub system but anyone can freely not only read the assembly code but also experiment with it, perhaps on a virtual machine.

The announcement arrived of the agreement that sees Microsoft buy the hosting service for software projects GitHub for $7.5 billion in Microsoft stock. The rumors of the deal begun last week but two years ago Microsoft had already attempted the acquisition.

GitHub is a hosting service for software projects that use the Git distributed version control software, one of the inventions of Linus Torvalds, famous above all for being the father of the Linux operating system. The company behind the service was founded in 2008 with its office in San Francisco, initially as Logical Awesome and since 2010 as GitHub, Inc. rapidly achieving great success.
