  • GNU Guix: Substitutes now also available from bordeaux.guix.gnu.org

    There have been a number of different project operated sources of substitutes, for the last couple of years the default source of substitutes has been ci.guix.gnu.org (with a few different URLs).

    [...]

    This change is an important milestone, following on from the work that started on the Guix Build Coordinator towards the start of 2020.

    Back in 2020, the substitute availability from ci.guix.gnu.org was often an issue. There seemed to be a number of contributing factors, including some parts of the architecture. Without going too much in to the details of the issues, aspects of the design of the Guix Build Coordinator were specifically meant to avoid some of these issues.

    While there were some very positive results from testing back in 2020, it's taken so long to bring the substitute availability benefits to general users of Guix that ci.guix.gnu.org has changed and improved significantly in the meantime. This means that any benefits in terms of substitute availability are less significant now.

    One clearer benefit of just having two independent sources of substitutes is redundancy. While the availability of ci.guix.gnu.org has been very high (in my opinion), having a second independent substitute server should mean that if there's a future issue with users accessing either source of substitutes, the disruption should be reduced.

    I'm also excited about the new possibilities offered by having a second substitute server, particularly one using the Guix Build Coordinator to manage the builds.

    Substitutes for the Hurd is already something that's been prototyped, so I'm hopeful that bordeaux.guix.gnu.org can start using childhurd VMs to build things soon.

    Looking a bit further forward, I think there's some benefits to be had in doing further work on how the nar and narinfo files used for substitutes are managed. There are some rough plans already on how to address the retention of nars, and how to look at high performance mirrors.

    On the internet you are never alone, and because of that at Mozilla we know that we can’t work to build a better internet alone. We believe in and rely on our community — from our volunteers, to our staff, to our users and even the parent’s of our staff (who also happen to be some of our power users). For Father’s Day, Mozilla’s Natalie Linden sat down with her father, big wave surf legend and surfboard maker, Gary Linden to talk the ocean, the internet and where humanity goes from here.

    We should probably start by telling people who we are. I am Natalie Linden, the Director of the Creative Studio in Mozilla marketing.

  • A revival at the intersection of open source and open standards – TechCrunch

    Tremendous technological innovation and transformative power are possible for the future if we re-energize the spirit of collaboration between the open-standards and open-source communities.

  • Open Source, Open Standards, and the Need for Collaboration

    “Our world has big problems to solve,” says Guy Martin, executive director of OASIS Open, and finding solutions will require open source and open standards communities to work together.

    In a recent article at TechCrunch, Martin describes the differences between open source and open standards but also examines their similarities and common goals, such as interoperability, innovation, and choice.

  • 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.
