  • 7 valuable programming languages for sysadmins in 2019

    Once upon a time, encouraging a system administrator to learn a programming language might have been wonky career advice. Programming languages are for programmers, after all—you know, the people who write code for a living. The sysadmin just keeps everything up and running.

    That’s a reasonable but dated thought process. In today’s multi-cloud and hybrid cloud environments, which are increasingly automated and managed with code, strategically learning a language (or several) is often a smart move. This fact doesn’t mean you’re now doing double duty as an application developer, but rather that in modern IT environments some traditional sysadmin duties have become more code-driven. Factor in related trends such as containers, microservices, and orchestration, and you begin to understand why automation has been such a hot topic in IT. We need automation to keep things running smoothly as systems scale in production, all the more so given today’s distributed computing environments.

    If you’re a sysadmin, you could learn any programming language just for the heck of it. No one’s stopping you. But some languages make particular sense. Your mileage may vary depending on factors like your infrastructure, applications, codebases, toolchains, and so on. Let’s look at seven languages worth considering for today’s sysadmin.

  • Bzip2 uses Meson and Autotools now — and a plea for help

    There is a lot of activity in the bzip2 repository!

    Perhaps the most exciting thing is that Dylan Baker made a merge request to add Meson as a build system for bzip2; this is merged now into the master branch.

  • Debian GSoC Kotlin project blog: Converting build files to Groovy; week 2 update

    I spent the first two weeks on updating build files of Kotlin to groovy so that we can reduce the dependency on kotlin-dsl while packaging Kotlin.

    task("dist") is the task that we call in order to build Kotlin 1.3.30 so it would be enough to translate and deal with only those subprojects which are involed in the "dist" task graph. I wrote this code here find out exactly which tasks from which subprojects are being called; the build files of these subprojects are also shown.

    There was a total of about 83 subprojects involved in the build process, out of these about 67 had build files written in kotlin-dsl. During this week I translated about 40 of those build files, so only 27 more remain. I have also translated the root projects build file. My work could be seen here.

    The build logic for the build files are written in Kotlin and placed in the $rootDir/buildSrc directory. Kotlin supports writing custom extension functions like fun String.customfunction() but groovy doesnt support this behaviour, so I had to introduce intermediate functions for these functions in the build logic so that these function can be invoked from within the groovy buildfiles.

  • 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.
