  • GNU Linux-libre Kernel 4.4 Officially Released for Those Who Want 100% Freedom

    The guys over at the GNU Linux-libre project have had the great pleasure of announcing the release and immediate availability for download of the GNU Linux-libre 4.4 kernel on January 10, 2016.

  • With Skylake Out, It's Becoming Easier To Build A Cheap Haswell Xeon Linux System

    Now that Skylake Xeon processors are appearing at major Internet retailers in sufficient quantities (such as the recently reviewed Intel Xeon E3 1245 v5), prices on older-generation Xeon CPUs are falling further. With prices on DDR3, SSDs, and Haswell-compatible motherboards also continuing to fall, it's possible to build a sufficiently powerful yet cheap Haswell Xeon system.

  • The Intel Graphics Highlights Of The Linux 4.5 Kernel
  • Neat drm/i915 stuff for 4.5

    Kernel version 4.4 is released, it's time for our regular look at what's in store for the Intel graphics driver in the next release.

  • Intel Knights Landing Perf Support Comes To Linux 4.5

    Ingo Molnar has already been sending in his many Git pull requests for the newly-opened Linux 4.5 merge window.

  • Cgroup v2 Is To Be Made Official With Linux 4.5

    The cgroup v2 interface will be made official with the in-development Linux 4.5 kernel.

    Maintainer Tejun Heo sent in the cgroup changes today for the Linux 4.5 merge window. About the new interface he notes, "cgroup v2 interface is now official. It's no longer hidden behind a devel flag and can be mounted using the new cgroup2 fs type. Unfortunately, cpu v2 interface hasn't made it yet due to the discussion around in-process hierarchical resource distribution and only memory and io controllers can be used on the v2 interface at the moment."

  • 4.4 Linux Kernel Long-Term Support Release is Now Available

    Linus Torvalds yesterday released the Linux 4.4 kernel. This is a long-term support (LTS) release, as was determined at the Linux Kernel Summit and announced in October by Greg Kroah-Hartman, who will maintain it for 2 years.

    This release checks in at more than 20.8 million lines of code, which is up considerably from Version 4.1, released in June 2015 with slightly more than 19.5 million lines of code, according to Phoronix. For historical comparison, version 0.01 of the Linux kernel -- released in 1991 -- had just 10,239 lines of code (source: Wikipedia).

  • LinuxChanges

    Summary: This release adds support for 3D support in virtual GPU driver, which allows 3D hardware-accelerated graphics in virtualization guests; loop device support for Direct I/O and Asynchronous I/O, which saves memory and increases performance; support for Open-channel SSDs, which are devices that share the responsibility of the Flash Translation Layer with the operating system; the TCP listener handling is completely lockless and allows for faster and more scalable TCP servers; journalled RAID5 in the MD layer which fixes the RAID write hole; eBPF programs can now be run by unprivileged users, they can be made persistent, and perf has added support for eBPF programs aswell; a new mlock2() syscall that allows users to request memory to be locked on page fault; and block polling support for improved performance in high-end storage devices. There are also new drivers and many other small improvements.

Release of PostgreSQL 11 Beta 1

  • PostgreSQL 11 Beta 1 Released!
    The PostgreSQL Global Development Group announces that the first beta release of PostgreSQL 11 is now available for download. This release contains previews of all features that will be available in the final release of PostgreSQL 11, though some details of the release could change before then. In the spirit of the open source PostgreSQL community, we strongly encourage you to test the new features of PostgreSQL 11 in your database systems to help us eliminate any bugs or other issues that may exist. While we do not advise for you to run PostgreSQL 11 Beta 1 in your production environments, we encourage you to find ways to run your typical application workloads against this beta release.
  • PostgreSQL 11 Beta 1 Released With JIT Compilation, More Performance Tuning
    The first beta of PostgreSQL 11.0 is now available for testing. Just yesterday we happened to be talking about the new features coming for PostgreSQL 11 and today happened to mark the beta availability. PostgreSQL 11 is bringing continued performance optimizations, better handling of large data sets, usability improvements. initial JIT compilation support by making use of LLVM, and more.

A free e-learning tool for creating digital content

It's common to see a software app stand still—no new versions, no updates. Eventually, it gets overtaken by advancing technology and its user base drifts away. Open source software is not immune to this fate, but it is easier to revive than commercial software, where optimistic accountants cling to the hope that it still holds financial value. eXeLearning (also called eXeLearn, or eXe), an open source XHTML editor that was created with support from Auckland University of Technology, University of Auckland, and Tairawhiti Polytechnic, achieved a measure of popularity among its target audience. The introduction to the version 1 manual described it as "an authoring environment to assist teachers and academics in the design, development, and publishing of web-based learning and teaching materials without the need to become proficient in HTML or complicated web-publishing applications." Despite a few annoying glitches, I liked and recommended that program. However, development stalled around 2010 and eXeLearning fell off my recommended list. eXeLearning is back on my list now.

Graphics: Vega and Vulkan

  • Vega 20 GPU Support & VCN Clock/Power Gating Sent In For Linux 4.18
    Last week was the main AMDGPU features update for Linux 4.18 via DRM-Next while today a secondary pull request of further feature work has been submitted. Last week's AMDGPU update included Vega M GPU support for Kabylake G hardware, reserving the initial scan-out buffer prior to the driver initialization for a more seamless console to driver experience, Raven Ridge GFXOFF support, various Vega 10 updates, and more.
  • NVIDIA 396.24.02 Linux Driver Brings New Vulkan Extensions
    The NVIDIA 396.24.02 Linux driver is available today and while it's a beta update, it ends up being quite an exciting release thanks to new Vulkan extensions. The newly-supported Vulkan extensions for the Linux driver build include VK_KHR_draw_indirect_count, VK_EXT_global_priority, and VK_KHR_get_display_properties2.
  • Vulkan 1.1.76 Released With KHR_draw_indirect_count & KHR_get_display_properties2
    Vulkan 1.1.76 has just been released ahead of the US Memorial Day weekend with new extensions to excite Vulkan developers. The two new extensions in Vulkan 1.1.176 are VK_KHR_get_display_properties2 and VK_KHR_draw_indirect_count, both of which are notable additions.
  • Vulkan Adds An Exception To Address Wine's Code License Incompatibility
    The Vulkan's documentation/generator being re-licensed from an MIT-style license to the Apache 2.0 license had caused problems for the Wine project supporting newer than Vulkan 1.0.51, but fortunately that issue has been resolved. The previous re-licensing of Vulkan-Docs has caused some problems for the LGPL-licensed Wine code, as we've covered previously, but that technicality has now been addressed with The Khronos Group adding an exception to their license to benefit the Wine project and others using code generated from the Vulkan vk.xml reference file so as not to have (L)GPL and Apache licenses clash.

TUXEDO InfinityBook Pro 13 Is the First Laptop Preloaded with openSUSE Leap 15

The OpenSuSE Project announced today that openSUSE Leap 15 is available for download as 64-bit installation images, which users would need to write on USB flash drives or DVDs to install the operating system on their personal computers. However, the openSUSE Leap 15 operating system also comes preloaded with the TUXEDO InfinityBook Pro 13 laptop we reviewed last year and Linode cloud images. "Today’s public release of Leap 15 aren’t only released as DVD and Network ISO: Linode and hardware vendor TUXEDO Computers have cloud images through of Leap ready, too. While the brand new TUXEDO InfinityBook Pro 13 is immediately available with Leap 15 preinstalled and ready-to-run, Linode has Leap available for all infrastructure needs," said openSUSE Project's Douglas DeMaio in today's announcement.
