Programming: YaST Development Sprint, FLANG Fortran Compiler, Emacs for Vim Users, Bash for Sysadmins

  • Highlights of YaST Development Sprint 91

    Let’s start with a redemption story. Some time ago we implemented feature fate#326485 which requested dropping the “Package Groups” view from the package manager UI. That was quite an easy task.

    However, a few weeks later we got a bug report that the lists of recommended, suggested, etc… packages couldn’t be displayed anymore. It turned out that, in the Qt package manager front-end, the removed “Package Groups” view not only used to display the static group data from the packages but it also contained some special computed package lists like orphaned, suggested or recommended packages. So these lists were lost as a collateral damage of removing the “Package Groups” view.

    The ncurses package manager was not affected by the same problem because, in that front-end, those views are grouped in a separate “Package Classification” section. So the task for this sprint was to somehow revive the lists in Qt and make them again available to the users.

    We partly reverted the Package Groups removal and restored displaying those special package groups. To make it consistent we also use the “Package Classification” name for the view, like in the ncurses package manager.

  • FLANG Fortran Compiler Preparing To Land In The LLVM Source Tree

    It looks like the FLANG Fortran compiler (also previously referred to as f18) could soon be landing in the LLVM source tree and in time for the LLVM 10.0 branching. 

    Earlier this year the LLVM Foundation approved this Fortran compiler led by NVIDIA for integration as an official sub-project. There has been some roundabouts on this latest naming whether it be f18, Fortran, or FLANG, but in the end the FLANG name has been the consensus with being to Fortran as Clang is to C/C++/Objective-C. 

  • Emacs for Vim users: Getting started with the Spacemacs text editor

    I use Vim a lot. I'm a site reliability engineer (SRE), and Vim is the one thing I know I can access on every machine in our fleet. I also like Emacs, with its wide variety of useful packages, ease of extending, and its many built-in tools. Because they each have their own set of commands, I have to actively switch codes in my head (usually after typing :wq in Emacs or trying to C+X in Vim). The Evil package for Emacs helps quite a bit by making Emacs behave more like Vim, but there is some effort required to set it up the first time.

  • 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.
