  • Fedora 32 Will Feature Bleeding-Edge Compilers Again With LLVM 10 + GCC 10

    Fedora Linux is on track to deliver another bleeding-edge compiler toolchain stack with Fedora 32 due out this spring. 

    Fedora's spring releases have tended to always introduce new GNU Compiler Collection (GCC) releases that are generally out a few weeks before the April~May Fedora releases. Thanks to Red Hat employing several GCC developers that collaborate with Fedora, they tend to stick to ensuring Fedora ships new GCC releases quite quickly while managing minimal bugs -- in part due to tracking GCC development snapshots well before launch to begin the package rebuilds. 

  • What makes Python a great language?

    I know I’m far from the only person who has opined about this topic, but figured I’d take my turn.

    A while ago I hinted on Twitter that I have Thoughts(tm) about the future of Python, and while this is not going to be that post, this is going to be important background for when I do share those thoughts.

    If you came expecting a well researched article full of citations to peer-reviewed literature, you came to the wrong place. Similarly if you were hoping for unbiased and objective analysis. I’m not even going to link to external sources for definitions. This is literally just me on a soap box, and you can take it or leave it.

    I’m also deliberately not talking about CPython the runtime, pip the package manager, venv the %PATH% manipulator, or PyPI the ecosystem. This post is about the Python language.

    My hope is that you will get some ideas for thinking about why some programming languages feel better than others, even if you don’t agree that Python feels better than most.

  • 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.
