    My trusty laptop’s speakers gave up the ghost. I don’t like to sit around in headphones all the time, I don’t have any other speakers, and the replacements are still being manhandled by the postman.

    I’d get used to the austerity if I hadn’t started missing calls from a friend. That’s unacceptable! But what am I supposed to do? Buy extra gadgets just to throw them away after a week? Nope, I’m not that kind of a person.

    But hey – I have a Librem 5! It has a speaker. It’s open. I have control over it, and I’m a hacker too. So I should be able to come up with a hack to turn it into a speaker for my laptop, right?

    One of the fields that can be configured by each user, is the link to other platforms (Github, LinkedIn, Twitter, Telegram, etc), so querying an LDAP server could suffice to get the list of users.

  • 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.
