  • mintCast 338.5 – The Ripple Effect

    In our Innards section, we ask Owen how Linux is improving the lives around him.

    And finally, some feedback and a few suggestions

  • Buttery Smooth Fedora | LINUX Unplugged 361

    Fedora's getting to work and reconsidering some long held-assumptions.

    Plus the best tool for getting things done on Linux, we take a look at openSUSE Leap 15.2, and breathe new life into an old Pebble.

  • Intel Architectural LBR Support Going Into Linux 5.9

    Intel CPUs have long supported LBR for last branch records as a means of recording the branches to which software has taken along with exposing other control flow information. This has relied upon model-specific registers while with future Intel CPUs this is being folded into a more universal CPU architectural feature. Support for Intel "Arch LBR" is set to come later this year with the Linux 5.9 kernel.

    The Linux kernel has been working with the existing MSR-based LBR functionality where with the likes of the perf subsystem can be used for recording the branches taken and other control flow information exposed for analysis and profiling. Intel recently has been working on added this Architectural LBR support to the Linux kernel.

  • First powerpc64 snapshots available

    Since we reported the first bits of powerpc64 support going into the tree on 16 May, work has progressed at a steady pace, resulting in snapshots now being available for this platform.

  • Website hosting on Raspberry Pi 4 with Mythic Beasts
  • [Old] Produce your own physical chips. For free. In the Open.

    Today, in a FOSSi Dial-Up talk, Tim Ansell of Google announced SkyWater PDK, the first manufacturable, open source process design kit. What differentiates this PDK from previous attempts is the fact that it is manufacturable: with this PDK, you can actually produce chips with the SkyWater foundry in the 130nm node.

    That leaves you as chip designer only with one road block: money. Manufacturing chips is expensive – even for more than a decade old nodes like the 130nm node, you need to spend at least a couple thousand dollars.

    You know what? Don’t worry – Google and efabless have got you covered! They are providing completely free of cost chip manufacturing runs: one in November this year, and multiple more in 2021. All open source chip designs qualify, no further strings attached!

  • New Release: Tor Browser 9.5.2

    Tor Browser 9.5.2 is now available from the Tor Browser download page and also from our distribution directory. This is an Android-only release.

    This release updates Firefox to 68.10.1esr.

  • against testing

    I really dislike writing tests. There's some amount of discomfort I'd be willing to sustain if I felt it they were beneficial, but I also find they're rarely worth the bother.

    In order to be effective, a test needs to exist for some condition not handled by the code. However, typically when the same mind writes the code and the tests, the coverage overlaps. Errors arise from unexpected conditions, but due to their unexpected nature, these are the conditions which also go untested.

  • I now think that blog 'per day' pages with articles are a mistake

    There's a bit of me that's sad about this shift in blog design and web usage; the per-day, per-month, and per-year organization had a pleasant regularity and intuitive appeal. But I think its time has passed. More and more, we're all tending toward the kind of minimal URL structure typical of static sites, even when we have dynamic sites and so could have all the different URL structures and ways of accessing our pages that we could ask for.

Samsung, Red Hat to Work on Linux Drivers for Future Tech

The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. Read more

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • 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.
