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 topics are Pointers and Linked Lists. Start by watching this presentation:

  • Python programming language: Pyboard D-series arrives for MicroPython robots

    The new Pyboard D-series micro-controller is now available for purchase at a rather hefty price of £43 ($56), offering developers a low-powered device for running programs created with MicroPython, a stripped-back version of the hugely popular Python 3 programming language.

  • Commenting Python Code

    Programming reflects your way of thinking in order to describe the single steps that you took to solve a problem using a computer. Commenting your code helps explain your thought process, and helps you and others to understand later on the intention of your code. This allows you to more easily find errors, to fix them, to improve the code later on, and to reuse it in other applications as well.

    Commenting is important to all kinds of projects, no matter whether they are - small, medium, or rather large. It is an essential part of your workflow, and is seen as good practice for developers. Without comments, things can get confusing, real fast. In this article we will explain the various methods of commenting Python supports, and how it can be used to automatically create documentation for your code using the so-called module-level docstrings.

  • Alibaba Dragonwell8 : The In-house OpenJDK Implementation At Alibaba

    Alibaba requires no introduction. It is one of the popular and largest multinational conglomerate founded by Jack Ma, a business magnate and philanthropist from China. It is also world’s fifth-largest internet company by revenue. It specializes in various sectors such as e-commerce, retail, Internet and technology. Alibaba team has provided significant contribution to open source projects. One such project is OpenJDK. The development team at Alibaba has developed many Java-based applications over the years. They have adopted OpenJDK and created their own JDK named “Alibaba Dragonwell8”. It is the downstream version of OpenJDK and completely open source.

    Alibaba Dragonwell is optimized for developing e-commerce, financial, logistics applications which are running on their 100k+ servers. It is certified as compatible with the Java SE standard. It is currently supports Linux/x86_64 platform only. Let us hope they will extend the support to Unix and other platforms soon. In this guide, we will see how to install Alibaba Dragonwell8 in Linux. I have tested this guide on Ubuntu 18.04 LTS server. However, it should work on other Linux distributions as well.

  • 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.
