  • Bootlin toolchains updated, 2021.11 release - Bootlin's blog

    Bootlin has been offering since 2017 a large set of ready to use pre-compiled cross-compilation toolchains at toolchains.bootlin.com. These toolchains are available for a wide range of CPU architectures and CPU variants, and support either the glibc, uClibc-ng or musl C libraries, where applicable.

    It’s been quite some time since the last release of those toolchains, so we took the opportunity of this quiet period between Christmas and New Year to finally update the toolchains. We’re happy to announce that we have now published a total of 187 toolchains targeting 46 different CPU architecture variants. As the toolchain release name suggests, they are now built with Buildroot 2021.11.

  • Excellent Free Tutorials to Learn Coq - LinuxLinks

    Coq is a dependently typed language. This means that the types of the language may depend on the values of variables. In this respect, it is similar to other related languages such as Agda, Idris, F*, Lean, and others. Via the Curry-Howard correspondence, programs, properties and proofs are formalized in the same language.

    Coq is developed in OCaml and shares some syntactic and conceptual similarity with it. Coq is a language containing many fascinating but difficult topics.

  • Experts Detail Logging Tool of DanderSpritz Framework Used by Equation Group Hackers

    Cybersecurity researchers have offered a detailed glimpse into a system called DoubleFeature that's dedicated to logging the different stages of post-exploitation stemming from the deployment of DanderSpritz, a full-featured malware framework used by the Equation Group.

    DanderSpritz came to light on April 14, 2017, when a hacking group known as the Shadow Brokers leaked the exploit tool, among others, under a dispatch titled "Lost in Translation." Also included in the leaks was EternalBlue, a cyberattack exploit developed by the U.S. National Security Agency (NSA) that enabled threat actors to carry out the NotPetya ransomware attack on unpatched Windows computers.

  • DragonFlyBSD Now Has Working Support For Intel Whiskey Lake Graphics - Phoronix

    The BSDs continue to lag behind Linux when it comes to the graphics driver support, but this time the Intel Whiskey Lake graphics should have been in long ago -- and believed to be -- but adding the PCI IDs were forgotten.

    Back in December of 2020 was a syncing of the Intel graphics driver PCI IDs from Linux 5.8 into the DragonFlyBSD kernel at the time. It should have been a straight-forward update for expanding the support given the commonality of the Intel Gen9 graphics at the time and DragonFlyBSD routinely porting over code from Intel's i915 Linux kernel graphics driver. Last year's commit was intended to bring support for Coffee Lake, Amber Lake, Whiskey Lake, and Comet Lake graphics on Intel processors. Unfortunately, the Whiskey Lake PCI IDs didn't end up being added to the driver list at the time.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.

Red Hat Hires a Blind Software Engineer to Improve Accessibility on Linux Desktop

Accessibility on a Linux desktop is not one of the strongest points to highlight. However, GNOME, one of the best desktop environments, has managed to do better comparatively (I think). In a blog post by Christian Fredrik Schaller (Director for Desktop/Graphics, Red Hat), he mentions that they are making serious efforts to improve accessibility. Starting with Red Hat hiring Lukas Tyrychtr, who is a blind software engineer to lead the effort in improving Red Hat Enterprise Linux, and Fedora Workstation in terms of accessibility. Read more
