  • Rails waves goodbye to mimemagic, welcomes Marcel to fix GPL MIME drama

    The maintainers of Rails, a Ruby-based framework for making web apps, have released three new versions to resolve a software licensing conflict that surfaced last week.

    A Rails component called Active Storage included a dependency called mimemagic, which turned out to have been distributed under the wrong license. The mimemagic software library provided a component of Rails called Active Storage with mime type data – used to identify file formats – and was initially distributed under an MIT license.

    But mimemagic has a dependency of its own called shared-mime-info that is distributed under the GPLv2 license. Under the terms of the GPLv2 license, mimemagic should have been GPLv2 licensed as well.

    When the author mimemagic learned of the error, he withdrew the previous MIT-licensed version of his code, breaking many app build processes, and issued new versions under GPLv2.

  • 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.
