  • Python and shell tools

    I'm not a pythonista, and what little I know about Python for data work amounts to a few published recipes. Out of curiosity, I sometimes re-do those recipes with the GNU/Linux tools I use every day. Below are three such re-doings from Python 2.7 (default on my Debian 10 system, but soon to reach end-of-life).

    Please note that this post isn't meant to be a "which is best?" contest between Python and shell tools. Each world of commands has its pro's and con's, and Python users have access to a large number of general and specialised data-processing tools. Personally, I like the versatility of shell tools and command chains, and I like AWK's speed and flexible syntax (as readers of this blog will know).

  • KDevelop - possibly new release coordinator

    After many days and weeks of thinking and waiting for better person to appear (nobody appeared) I decided to take the initiative (it took a lot) and try my luck at becoming new KDevelop release coordinator.

    My reasoning as I mentioned in my mail is that if there was someone better for the job the position would be filled by now. And I wish for KDevelop to be a healthy project which can rival those monsters like MSVS, NetBeans, Eclipse, Atom, MSVC…

  • Modernizing Java to keep pace in a cloud-native world

    Java is no spring chicken and some are even referring to it as a “vintage language”. Despite its popularity, there are some complaints about it. In our new cloud-native world, why does Java need to evolve? In order to evolve to keep up with modern, cloud-native apps, Java needs to keep all of what makes it so dependable, while also being able to function in new app environments.
    Don’t worry, you are not the only one who feels old when you hear Java being described as a “vintage” programming language. While Java has been around since 1995, it is certainly not ready to retire (or rather, be retired), and continues to rank among the top languages TIOBE index. In fact, no other language has been so popular for so long.

    However, it is not without its issues, including sometimes being too clunky to keep up with some of the newer programming languages, not agile and flexible enough to work in this new world of containers, and not really relevant in applications that are not coded to be Java first. While they say you can’t teach an old dog new tricks, you can rethink how it performs what they already know.

  • 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.
