  • The mysterious case of the Linux Page Table Isolation patches

    tl;dr: there is presently an embargoed security bug impacting apparently all contemporary CPU architectures that implement virtual memory, requiring hardware changes to fully resolve. Urgent development of a software mitigation is being done in the open and recently landed in the Linux kernel, and a similar mitigation began appearing in NT kernels in November. In the worst case the software fix causes huge slowdowns in typical workloads. There are hints the attack impacts common virtualization environments including Amazon EC2 and Google Compute Engine, and additional hints the exact attack may involve a new variant of Rowhammer.

  • systemd Breached One Million Lines Of Code In 2017

    Systemd had a busy 2017 and its code-base is now up to over one million lines.

    Systemd in 2017 saw 3,443 commits, which is actually the lowest point since 2012. But the commits were larger with having 418,903 lines of code added and 119,975 lines removed: a net gain of nearly 300,000 lines of code.

  • NuTyX 10.0-rc1 is release

    The NuTyX team is proud to annonce the first release candidat of the next major version 10 of NuTyX.

  • Arcan 0.5.4, Durden 0.4

    From left to right, we have a little Raspberry  running the ‘prio’ WM using the broadcom binary blob drivers (so lacks some of the features needed to run durden), with arcan and terminals eating up all of 20MB of ram. The left Macbook running OSX with Arcan/Durden in fullscreen, retina resolution, of course. The Macbook on the right is running the same system on OpenBSD 6.2. The three-headed monkey behind them is a voidlinux setup with two instances, one on an intel GPU, the other on an AMD GPU. If only the android devices on the wall could be brought in on the fun as well…

  • Arcan 0.5.4 Display Server Released With Durden 0.4 Desktop

    Remember Arcan? The Linux display server built off a game engine. The project is ending 2017 with the release of the Arcan 0.5.4 display server and its associated Durden v0.4 desktop.

    With the Arcan 0.5.4 release, its X.Org-backend has been ported to OpenBSD, its VRbridge tool now has basic OpenHMD support, improvements to its Wayland protocol handling, and a lot more.

  • LinuxJournal, Which Ceased Publication Last Month Citing Poor Financial Condition, Secures Fresh Fund From Readers To Resume Operation

  • First results of the ROSIN project: Robotics Open-Source Software for Industry
    Open-Source Software for robots is a de-facto standard in academia, and its advantages can benefit industrial applications as well. The worldwide ROS-Industrial initiative has been using ROS, the Robot Operating System, to this end. In order to consolidate Europe’s expertise in advanced manufacturing, the H2020 project ROSIN supports EU’s strong role within ROS-Industrial. It will achieve this goal through three main actions on ROS: ensuring industrial-grade software quality; promoting new business-relevant applications through so-called Focused Technical Projects (FTPs); supporting educational activities for students and industry professionals on the one side conducting ROS-I trainings as well as and MOOCs and on the other hand by supporting education at third parties via Education Projects (EPs).
  • Baidu To Launch World’s First Intelligent Vehicle Infrastructure Cooperative Systems Open Source Solution By End Of 2018
    Baidu Inc. has announced it will launch the Apollo Intelligent Vehicle Infrastructure Cooperative Systems (IVICS) open-source solution by the end of 2018, leveraging its capabilities in autonomous driving to bring together intelligent vehicles and infrastructure to form a “human-vehicle-roadway” interplay – an important step toward developing future intelligent transportation.
  • Versity Open Sources Next Generation Archiving Filesystem
    The ScoutFS project was started in 2016 to address the rapidly growing demand for larger POSIX namespaces and faster metadata processing. The design goal for ScoutFS includes the ability to store up to one trillion files in a single namespace by efficiently distributing metadata handling across a scale out cluster of commodity compute nodes.

  • Epic Clock Clocks The Unix Epoch
    Admit it: when you first heard of the concept of the Unix Epoch, you sat down with a calculator to see when exactly 2³¹-1 seconds would be from midnight UTC on January 1, 1970. Personally, I did that math right around the time my company hired contractors to put “Y2K Suspect” stickers on every piece of equipment that looked like it might have a computer in it, so the fact that the big day would come sometime in 2038 was both comforting and terrifying. [Forklift] is similarly entranced by the idea of the Unix Epoch and built a clock to display it, at least for the next 20 years or so. Accommodating the eventual maximum value of 2,147,483,647, plus the more practical ISO-8601 format, required a few more digits than the usual clock – sixteen to be exact. The blue seven-segment displays make an impression in the sleek wooden case, about which there is sadly no detail in the build log. But the internals are well documented, and include a GPS module and an RTC. The clock parses the NMEA time string from the satellites and syncs the RTC. There’s a brief video below of the clock in action.
  • 3 top Python libraries for data science
    Python's many attractions—such as efficiency, code readability, and speed—have made it the go-to programming language for data science enthusiasts. Python is usually the preferred choice for data scientists and machine learning experts who want to escalate the functionalities of their applications. (For example, Andrey Bulezyuk used the Python programming language to create an amazing machine learning application.) Because of its extensive usage, Python has a huge number of libraries that make it easier for data scientists to complete complicated tasks without many coding hassles. Here are the top 3 Python libraries for data science; check them out if you want to kickstart your career in the field.
  • PortableCL 1.2 Still Coming While POCL 1.3 Will Further Improve Open-Source OpenCL
    It's been a number of months since last having any major news to report on POCL, the "PortableCL" project providing a portable OpenCL/compute implementation that can run on CPUs, select GPUs, and other accelerators. POCL 1.1 from March remains the current stable release while POCL 1.2 has been in the release candidate stage. The POCL 1.2 release candidates began last month with a few highlights like LLVM 7.0 support, device-side printf support, and HWLOC 2.0 library support.

New CloudBees Suite Addresses DevOps Gaps in Software Delivery

CloudBees is bringing a set of products into a new CloudBees Suite that it said will help companies of all sizes streamline the software development process. The new software is set to be announced Sept. 18 at the company’s DevOps World / Jenkins World conference in San Francisco. Jenkins is the open-source version of CloudBees, which is a commercial offering. A central piece of the CloudBees Suite is the CloudBees Core for unified governance of continuous delivery operations and processes used in DevOps. Software pipelines can also use Core to run software pipelines more efficiently in a self-managed way in the cloud or on-premises.
