Thursday 14th of June 2018 12:35:43 AM

Red Hat is the top open-source software company known for their Red Hat Enterprise Linux (RHEL) operating system, and they're always quick to address newly discovered security vulnerabilities that not only affect its enterprise-ready operating system but the entire Open Source and Free Software community.

Many modern microprocessors leverage the "lazy restore" function for floating point state (FPU), which is used when needed for improving the overall performance of the system when saving and restoring the state of apps in the internal memory when switching from one application to another.

  • A Session Suspension & Restoration Protocol Proposed For Wayland
    KDE Wayland developer Roman Gilg who started contributing to Wayland via last year's Google Summer of Code is proposing a new Wayland protocol for dealing with desktop session suspension and restoration. This protocol extension would allow for more efficient support for client session suspension and restoration such as when you are logging out of your desktop session and want the windows restored at next log-in or if you are suspending your system. While Roman Gilg is working on this protocol with his KDE hat on, he has been talking with Sway and GNOME developers too for ensuring this protocol could work out for their needs.

Server Domination by GNU/Linux

  • Security and Performance Help Mainframes Stand the Test of Time
    As of last year, the Linux operating system was running 90 percent of public cloud workloads; has 62 percent of the embedded market share and runs all of the supercomputers in the TOP500 list, according to The Linux Foundation Open Mainframe Project’s 2018 State of the Open Mainframe Survey report. Despite a perceived bias that mainframes are behemoths that are costly to run and unreliable, the findings also revealed that more than nine in 10 respondents have an overall positive attitude about mainframe computing. The project conducted the survey to better understand use of mainframes in general. “If you have this amazing technology, with literally the fastest commercial CPUs on the planet, what are some of the barriers?” said John Mertic, director of program management for the foundation and Open Mainframe Project. “The driver was, there wasn’t any hard data around trends on the mainframe.”
