  • How to Filter or Disable Blue Light on Ubuntu

    For most of our waking days, we are surrounded by screens. While it's not a big problem in itself, staring at screens well into the evening can result in a disturbance of the natural sleep cycle, which in turn, can result in health risks like insomnia, daytime fatigue, and more. The culprit behind this is the blue light emitted by these screens.

    This makes it pertinent that we remove, or, at the very least, filter the blue light from our screens. There are both manual and automated ways to disable the blue light on your Ubuntu system.

  • 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.
