Meltdown Patches and Problems

  • [Ubuntu] Meltdown and Spectre Status Update

    On Tuesday, January 9, 2018 we released Ubuntu kernel updates for mitigation of CVE-2017-5754 (aka Meltdown / Variant 3) for the x86-64 architecture.

  • Lubuntu 17.10.1 (Artful Aardvark) released!

    Lubuntu 17.10.1 has been released to fix a major problem affecting many Lenovo laptops that causes the computer to have BIOS problems after installing. You can find more details about this problem here.

    Please note that the Meltdown and Spectre vulnerabilities have not been fixed in this ISO, so we advise that if you install this ISO, update directly after.

    This release is no different in terms of features from the 17.10 release, and is comparable to an LTS point release in that all updates since the 17.10 release have been rolled into this ISO. You can find the initial announcement here.

  • Check Linux for Spectre or Meltdown vulnerability

    Devices running Linux are affected by Spectre and Meltdown vulnerabilities as much as their Windows counterparts.

    Development teams work on updated kernels for the various distributions, and users need to update browsers and other software to protect data against potential attacks.

    We talked about identifying whether your Windows PC or web browser is vulnerable already. A recently published script does the same for Linux systems. You may use it to check whether your Linux distribution is vulnerable.

  • Meltdown Patch Is Causing Problems for Some Ubuntu Linux Users

    Many Ubuntu Linux users who installed the latest kernel updates to fix the Meltdown CPU vulnerability found themselves stuck in a boot loop and had to revert back to a previous version.

    The problem affected mostly Ubuntu 16.04 (Xenial Xerus), which is a long-term support (LTS) release. Soon after the 4.4.0-108 kernel update was released to fix the Meltdown vulnerability, users flooded the Ubuntu Forums and bug tracker to report booting problems.

  • Meltdown Update Kernel doesnt boot
  • Major Linux distros have Meltdown patches, but that's only part of the fix

    The Intel Meltdown security problem is the pain that just keeps hurting. Still, there is some good news. Ubuntu and Debian Linux have patched their distributions. The bad news? It's becoming clearer than ever that fixing Meltdown causes significant performance problems. Worst still, many older servers and appliances are running insecure, unpatchable Linux distributions.

  • 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.
