  • Antoine Beaupré: Leaving Freenode

    This matters if you care about IRC, the internet, open protocols, decentralisation, and, to a certain extent, federation as well. It also touches on who has the right on network resources: the people who "own" it (through money) or the people who make it work (through their labor). I am biased towards open protocols, the internet, federation, and worker power, and this might taint this analysis.

  • Preliminary thoughts about save-file in EasyOS
  • Steinar H. Gunderson: LZ24

    I cooked together a new compression format over the weekend; it's based on experiences I had way back when I worked on Snappy, and intends to be as kind as possible to the branch predictor. I don't intend to productionize it because it isn't competitive (see below), but I still think the idea is interesting enough to put out there.

    The implementation isn't much; it's generally slightly less dense than Snappy, but decompresses faster than it, but it thoroughly trounced by LZ4 still (factor 2–3x!). I don't know if that's LZ4's format being inherently faster or just if it's about the massive amount of tuning in the implementation; back when we open-sourced Snappy, it was in the same league as LZ4 (well, faster to begin with, and then LZ4 picked up a lot of the same tricks and had a simpler format), so evidently, a lot of things have happened, and I don't have the patience anymore to tweak individual cycles.

  • Jonathan Dowland: OpenJDK Runtime Containers

    The UBI OpenJDK containers are full fat developer containers: they've got the full OpenJDK distribution in them (including javac etc.); they include Maven and there are various quality-of-life additions such as a Prometheus agent for metrics gathering in OpenShift and a run-java script to control launching the eventual application, as well as OpenShift Source-To-Image (S2I) integration.

  • Jonathan Dowland: Answering my own Template Haskell question

    A couple of weeks ago I stumbled across a Template Haskell question on the Haskell sub-reddit. This was quite exciting because I rarely see TH questions, and this one was by someone working on something which was quite similar to what I had done: they were writing a code generator, and had pure functions of type Exp -> Exp -> Exp, but wanted to leverage TH's quasi-quotation syntax (e.g. [| \p -> p + 1 |]) as a syntactic short-hand. Alas these quasi-quotes are of type Q Exp, so the question becomes, how to escape Q?

  • Dirk Eddelbuettel: RcppArmadillo 0.10.5.0.0 on CRAN: New Upstream

    Armadillo is a powerful and expressive C++ template library for linear algebra aiming towards a good balance between speed and ease of use with a syntax deliberately close to a Matlab. RcppArmadillo integrates this library with the R environment and language–and is widely used by (currently) 865 other packages on CRAN.

    This new release brings Armadillo 10.5.0 which was released early on Friday. We had done one full test in the ‘10.5 rc1’ prerelease one week earlier, and did another test on 10.5.0 and this 0.10.5.0.0 RcppArmadillo release just for added rigour. The package was then uploaded to CRAN late Friday (my timezone). The automated process flagged one NOTE as a false positive (yet another instance of the well-known (yet dreaded) issue of ‘Suggests != Depends’ by one these 865 packages). This lead to a need of an inspection by one of the CRAN maintainers, and the weekend being the weekend it was only processed just now.

  • Charles Plessy: Trying R 4.1

    I am trying R 4.1 in a schroot experimental container, while waiting that Bullseye's release will allow the package to be uploaded to Sid and the needed dependencies to be recompiled.

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.
