  • New Chief Maintainer for the Qt Project

    Qt has been released as Open Source since its very first version all the way back in 1994. But development happened in a closed-source fashion inside the companies owning Qt (Trolltech and then Nokia). In 2011, we changed this. We took the big step and turned Qt into a real Open Source project, with a public governance structure consisting of Approvers, Maintainers and one Chief Maintainer.

    I had the honour of being the Chief Maintainer for the Qt Project since that time. It's been 11 fantastic years for Qt, where we've seen a huge amount of new features and work flowing into Qt. We've seen a large growth in our user base, and we released 2 major versions, 21 minor versions and countless patch level releases of Qt.

  • I wish Grafana dashboards and panels could have easy, natural comments

    Recently I was looking at a panel in one of our Grafana dashboards and noticed that its PromQL queries used avg_over_time() when it (now) felt as if max_over_time() was what the panel should be using. It's been years since I created this panel and last touched it, and I definitely no longer remember what I was thinking at the time. Did I have a good reason that avg_over_time() was necessary, or did an average just feel more correct for the purpose of the panel at the time I created it?

    We have Prometheus alert rules with similarly tangled PromQL expressions, but since Prometheus alert rules are (normally) configured in YAML text files that allow comments, most of our complicated and non-obvious alert rules have commentary about why they're that way, what options don't work, and so on. This commentary has periodically been extremely helpful for refreshing my mind about what on earth past me was thinking when he wrote the rule.

    Setting up Grafana panels and dashboards is normally done through their web GUI, which doesn't really offer any good way of writing this sort of commentary.

  • Compliment 0.3.13 | Meta Redux

    The new version of compliment has already been integrated in cider-nrepl 0.28.5 and it’s being used by CIDER’s 1.5-SNAPSHOT builds. That’s probably the easiest way to take it out for spin. I hope you’ll love this release and I hope I didn’t mess anything up!

    You might be wondering why I’m doing the release announcement this time around instead of compliment’s author and all-star Clojure hacker Alex Yakushev. Well, sadly Alex has been impacted much more by the war than me. He’s from Ukraine and is now fighting for the freedom of his country. In the mean time I’ll be helping Alex out a bit with the maintenance of compliment until he’s back home safe and sound.

  • Unbelievable: A single-file web server that runs on six OSes • The Register

    A bunch of almost unbelievably clever tech tricks come together into something practical with redbean 2: a webserver plus content in a single file that runs on any x86-64 operating system.

    The project is the culmination – so far – of a series of remarkable, inspired hacks by programmer Justine Tunney: αcτµαlly pδrταblε εxεcµταblε, Cosmopolitan libc, and the original redbean. It may take a little time to explain what it does, so bear with us. We promise, you will be impressed.

  • 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.

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
