  • How to Disable VIM Syntax Highlighting – Linux Hint

    The VIM editor provides a cool feature to highlight syntax based on whatever language you are programming in. This makes it easier to edit the code and visually understand the syntax of the code. However as a system admin or DevOps engineer you may find yourself editing many configuration files of various formats and on various remote machines and because of the systems you login to, the syntax highlighting makes the file unreadable in your session.

    Therefore in this post, we will show how to disable syntax highlighting in the .vimrc configuration file. This way all files that you open will have plain text, without any color schemes, and you can quickly get to work.

    I found myself frequently opening files and then disabling syntax highlighting dynamically, its more efficient to add the command to the .vimrc file on each machine you use.

  • 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.
