  • FOSS Means Kids Can Have a Big Impact

    Working at a company that creates free and open-source software (FOSS) and hosts all of our code on GitHub, my team and I at UserLAnd Technologies are used to seeing and reviewing contributions, which are called pull requests, from users. Recently, however, we received a pull request that is very special to me. It was from an eight-year-old, and not just any eight-year-old, but my daughter.

  • Eclipse Wild Web Developer adds a powerful YAML editor with built-in Kubernetes support

    YAML Ain’t Markup Language (YAML) has grown increasingly popular during the past few years. It is a human-readable text-based format for specifying configuration information and is used in many platforms, such as Kubernetes and Red Hat OpenShift.

    Eclipse Wild Web Developer is a language-based extension that provides a rich development experience for developing typical web and configuration files in the Eclipse IDE. According to the project page, “Eclipse Wild Web Developer relies on existing mainstream and maintained components to provide the language smartness, over popular configuration files like TextMate and protocols like Language Server Protocol or Debug Adapter Protocol.”

  • Next C++ workshop: Linked Lists, 11 April at 18:00 UTC

    Another workshop is coming up! Improve your C++ skills with the help of LibreOffice developers: we’re running regular workshops which focus on a specific topic, and are accompanied by a real-time IRC meeting. For the next one, the topic is Linked Lists. Start by watching this presentation:

  • What to do when Java SE 11 removes JNLP

    For about the past 15 years, an organization I work with has used the Java Network Launching Protocol (JNLP) to internally distribute a Java Swing desktop application to its users.

    To access the Java Swing application, users had to install a specific version of Java Platform, Standard Edition (Java SE) that contained support for JNLP. When they wanted to use the application, they would click on the link in the organization's intranet, and the Java Web Start (javaws) program would download the XML at the link, interpret it, download the current version of the application if necessary, and run it, all while managing the security sandbox where the application ran. In other words, it was a nice, low-ceremony way to distribute a completely configured application to everyone's desktop.

  • Qt sensors just got better on Android

    April was quite quiet so I decided to rewrite the Android sensors plugin (no, this is not a late April fool’s joke).

    Why on earth did I want to do that? Why try to fix something that works? After all, the current implementation faithfully served us for years!

    I decided to rewrite it after I did some performance tests that showed some surprising numbers. When I used the NDK API to get sensors data, the CPU usage dropped from over 60% to even less than 20% (it fluctuates from 15% up to 30%)! Yup, that’s a surprising performance improvement, which TBH I hadn’t expected at all!

    I expected it to be faster, as the NDK API doesn’t need to move the data to JAVA and then back to C/C++ world (via JNI) but, I never dreamed it would be that fast!

  • 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.
