  • Make Use Of ☛ How to Set Up a TFTP Server on Linux

    TFTP (Trivial File Transfer Protocol) was first described in 1980. It is a fairly old protocol published in June 1981 as TFTP Protocol revision 2 in RFC 783 (Request For Comments) by Karen R. Sollins.

    In the early days, the main goal of TFTP was to send and receive files over a network. In particular, it was used to transfer the files needed during boot to enable systems to boot over a network.

    Here’s how you can set up a TFTP server on a Linux machine.

  • Ghacks ☛ Linux Mint 21 Beta is now available for testing – gHacks Tech News

    Linux Mint 21 is almost ready. If you are interested in trying the next version of the popular Linux distribution early, you may download official beta ISO images to do so. All three Linux Mint desktop environments can be downloaded and tested.

    Linux Mint 21 is powered by Linux Kernel 5.15 and Ubuntu 22.04 LTs, which means that the Linux distribution will be supported until 2027 with security patches.

    Once the stable version of Linux Mint 21 released, Linux Mint 20.3 systems can be upgraded with the help of the new Linux Mint upgrade tool. It removes the need to run commands from a terminal window, and streamlines the upgrade process for most users because of that.

  • Ubuntu ☛ Introducing Ubuntu for Google Cloud’s Arm-based T2A virtual machines

    Canonical and Google Cloud today announce an optimised Ubuntu image for the preview of Tau T2A virtual machines (VMs) on Compute Engine. Google Cloud users will benefit from running Ubuntu, a popular cloud operating system, on a secure, scalable, and highly cost-effective cloud infrastructure. The Ampere® Altra® Arm-based T2A VMs are ideal for computing workloads including microservices, application servers, machine learning (ML), open source databases, and in-memory caches.

    Canonical has had a long-term strategy for Arm architecture for a decade. At Computex 2012, MiTAC demonstrated their first Arm Server, running Ubuntu. Ubuntu 14.04 LTS was also the pioneer in supporting Armv7-A Cortex-A15 chip and Armv8 SoCs. Since the start of our Arm journey, Canonical has been focused on solving challenges such as: mixed x86 and Arm environments; multiple SoCs; provisioning large deployments; and mixed public and private cloud deployments. Continuing this strategy, Canonical and Ampere have collaborated to bring SOC certified Ubuntu images to the market at launch. Today, the availability of optimised Ubuntu for T2A VMs enables developers to better address these challenges.

    • Mozilla ☛ Reworking our Visual Metrics Processing System – Mozilla Performance

      Our visual metrics processing system used to use two separate machines to produce visual metrics from our pageload tests. In this post, I’ll describe how we moved to a single-machine system that also brought about many other benefits for us.

      Note: If you’ve never heard of visual metrics before, they can be summed up as performance metrics processed from a video recording of a pageload. You can find more information about these from this article titled Improving Firefox Page Load, by Bas Schouten.

    • Mozilla ☛ Migrating to Browsertime for Performance Testing – Mozilla Performance

      Originally, we used a Web Extension for doing performance testing on Firefox in our Raptor test harness. But, we needed to add new features such as visual metrics, so in this post, I’ll briefly describe the steps we took to migrate Raptor to Browsertime.

      We now have enabled Browsertime by default in our Raptor harness both locally, and in Continuous Integration (CI) but for some time, we needed to use the flag `–browsertime` to enable it. This work started with Nick Alexander, Rob Wood, and Barret Rennie adding the flag in bug 1566171. From there, others on the Performance team (myself included), began testing Browsertime, preparing the Raptor harness, and building up the infrastructure required for running Browsertime tests in CI.

      Our primary motivation for all of this work was obtaining visual metrics. If you’ve never heard of visual metrics before, they can be summed up as performance metrics processed from a video recording of a pageload. You can find more information about these from this article titled Improving Firefox Page Load, by Bas Schouten. Initially, our visual metrics processing system used a two-machine system where one machine would run the test and the other would process the video recordings to obtain the metrics. This worked well for some time until we found some issues with it that were a large point of friction when it came to using our tooling. In Reworking our Visual Metrics Processing System, I describe these issues and how we overcame them. It suffices to say that we now use a single machine in CI, and that those issues were resolved.

  • Unix Men ☛ 5 Data Security Issues on Linux

    Every tech enthusiast knows that Linux comes with the freedom that hardly any other OS can offer. We don’t even have to get into the benefits that come with a large community and open source philosophy.

    However, some people (especially Linux newbies) tend to think that Linux can’t be harmed by cyberthreats at all.

    Hackers and scammers are getting ever more creative, so let’s talk about the security issues on Linux that can get you and your data in trouble.

  • The Register UK ☛ X.org servers updated, among many other X11 bits • The Register

    X.org has released a bunch of updates, which includes closing two security holes and, yes, this affects Wayland users too.

    A batch of updates to X.org’s suite of X11 servers and components just appeared. Among the new features, there were also fixes for two security holes mentioned in an X.org Foundation security advisory, which covers CVE-2022-2319 and CVE-2022-2320.

    Although the X window system is pretty old, it’s still everywhere, including on almost every xNix operating system that has a graphical desktop. Wayland users don’t get to be smug: they too rely upon XWayland, which is what lets them run most older apps. Together, these mean that X.org version 21.1.4 will be a necessary update for a lot of people, alongside XWayland version 22.1.3.

    It’s best to go into this series as blind as possible, but some context and history will really improve what you get out of it. It’s based on the culture around Flipnote Hatena (Flipnote Studio in the US). It was a program for the DSi that allowed anyone to create and share animations with each other. A very unique culture of highly talented people developed there until the service shut down on May 31, 2013 despite being popular.

    There was apparently a frantic bug-hunt involving “Project: Lumbergh [1]” yesterday that I was not involved in. From the description of the bug, it certainly sounded like it was a manifestation of “undefined behavior” as “Project: Lumbergh” was actinging differently between Linux and Mac OS-X (our testing and development platforms).
