  • How to flatten PDF documents - Tutorial

    A couple of days ago, I showed you how to redact information in Okular, the default PDF viewer in the Plasma desktop. The action is relatively simple to do, but it doesn't effectively destroy the redacted information, merely obscures it from the viewer.

    What I want to show you today is the second part of the puzzle - the flattening of PDF documents. Think an image with multiple layers, and then you save it all in a non-layered format. The information is then flattened into a single layer - the values of all the vertically stacked pixels are calculated - added/subtracted/whatever - and then presented as a single definitive computation of this action. The same with PDF, except it's more complicated, given the PDF structure. Let's do it.

  • 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.
