Linux KPTI Tests Using Linux 4.14 vs. 4.9 vs. 4.4

Friday 5th of January 2018 01:31:57 AM
Yet another one of the avenues we have been exploring with our Linux Page Table Isolation (KPTI) testing has been looking at any impact of this security feature in the wake of the Meltdown vulnerability when testing with an older Linux Long Term Support (LTS) release. In particular, when using a kernel prior to the PCID (Process Context Identifier) support in the Linux kernel that is used to lessen the impact of KPTI.

GNU: GCC 7.3 and LibrePlanet 2018 Keynote Speakers

  • GCC 7.3 Preparing For Release To Ship Spectre Patches
    GNU developers are preparing to quickly ship GCC 7.3 now in order to get out the Spectre patches, a.k.a. the compiler side bits for Retpoline with -mindirect-branch=thunk and friends. It was just this past weekend that the back-ported patches landed in GCC 7 while now GCC 7.3 is being prepared as the branch's next bug-fix point release.
  • Announcing LibrePlanet 2018 keynote speakers
    The keynote speakers for the tenth annual LibrePlanet conference will be anthropologist and author Gabriella Coleman, free software policy expert and community advocate Deb Nicholson, Electronic Frontier Foundation (EFF) senior staff technologist Seth Schoen, and FSF founder and president Richard Stallman. LibrePlanet is an annual conference for people who care about their digital freedoms, bringing together software developers, policy experts, activists, and computer users to learn skills, share accomplishments, and tackle challenges facing the free software movement. The theme of this year's conference is Freedom. Embedded. In a society reliant on embedded systems -- in cars, digital watches, traffic lights, and even within our bodies -- how do we defend computer user freedom, protect ourselves against corporate and government surveillance, and move toward a freer world? LibrePlanet 2018 will explore these topics in sessions for all ages and experience levels.

Open Source in 3-D Printing

  • 17,000% Cost Reduction with Open Source 3D Printing: Michigan Tech Study Showcases Parametric 3D Printed Slot Die System
    We often cover the work of prolific Dr. Joshua Pearce, an Associate Professor of Materials Science & Engineering and Electrical & Computer Engineering at Michigan Technological University (Michigan Tech); he also runs the university’s Open Sustainability Technology (MOST) Research Group. Dr. Pearce, a major proponent for sustainability and open source technology, has previously taught an undergraduate engineering course on how to build open source 3D printers, and four of his former students, in an effort to promote environmental sustainability in 3D printing, launched a business to manufacture and sell recycled and biodegradable filaments.
  • Open Source 3D printing cuts cost from $4,000 to only $0.25 says new study
    Slot die coating is a means of adding a thin, uniform film of material to a substrate. It is a widely used method for the manufacturing of electronic devices – including flat screen televisions, printed electronics, lithium-ion batteries and sensors. Up until recently, slot die components were only machined from stainless steel, restricting development and making the process expensive. Now slot dies for in-lab experimental use can be made on a 3D printer at a fraction of the cost.
  • Dutch firm unveils world's first 3-D-printed propeller
    Three-dimensional (3-D) printing technology has caught the logistics world's attention for its potential to save on warehouse and shipping costs by producing items on demand at any location. In the past two years, for example, UPS Inc. announced plans to partner with software developer SAP SE to build a nationwide network of 3-D printers for use by its customers, and General Electric Co. spent nearly $600 million to buy a three-quarters stake in the German 3-D printing firm Concept Laser GmbH. Recently, transportation companies have begun turning to the same technology for another application, creating the actual hardware used in vehicles that move the freight. For instance, in late 2016, global aircraft maker Airbus S.A.S. contracted with manufacturing firm Arconic Inc. to supply 3-D printed metal parts for its commercial aircraft.
