  • DRY enums for Absinth macros

    Absinth is a great GraphQL library for Elixir, but it brings a few challenges as it’s practically implemented using macros. One of these challenges is a DRY way of reusing enumerables in Absinth enums.

    [...]

    The only thing we had to do is to use require to require the module beforehand.

  • Gzip::Zopfli - another compression module

    Following on from the Gzip::Libdeflate I mentioned before, I also made this: Gzip::Zopfli

    It is based on the Zopfli gzip compression library from Google Research.

  • Weird architectures weren't supported to begin with

    You don’t know about any of the above until the bug reports start rolling in: users will report bugs that have already been fixed, bugs that you explicitly document as caused by unsupported configurations, bugs that don’t make any sense whatsoever.

    You struggle to debug your users’ reports, since you don’t have access to the niche hardware, environments, or corporate systems that they’re running on. You slowly burn out as an unending torrent of already fixed bugs that never seem to make it to your users. Your user base is unhappy, and you start to wonder why you’re putting all this effort into project maintenance in the first place. Open source was supposed to be fun!

    What’s the point of this spiel? It’s precisely what happened to pyca/cryptography: nobody asked them whether it was a good idea to try to run their code on HPPA, much less System/3906; some packagers just went ahead and did it, and are frustrated that it no longer works. People just assumed that it would, because there is still a norm that everything flows from C, and that any host with a halfway-functional C compiler should have the entire open source ecosystem at its disposal.

  • Woodruff: Weird architectures weren't supported to begin with

    William Woodruff has posted a rant of sorts on the adoption of Rust by the Python Cryptography project, which was covered here in February.

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.
