Migrate a PostgreSQL Container to a New Major Version

Published on in πŸ‘¨β€πŸ’» Dev

A few weeks ago PostgreSQL 11 was released with a few new features and probably also a lot of improvements and bug fixes since the last release. Although I don’t really have the need to update to the latest version (I just use PostgreSQL as database for my Nextcloud and Miniflux installations), I wanted to migrate it though, to have everything up to date and probably profit from those smaller improvements.

Hugo Is Awesome - Why I moved from Ghost to Hugo

Hugo is a framework to build static websites. Yesterday I migrated this blog from Ghost - a dynamic NodeJS based CMS - to Hugo, not only to reduce the hardware requirements (a static page uses way less resources), but also to simplify my setup.

Back to Ubuntu

Published on in πŸ‘¨β€πŸ’» Dev

Ubuntu was the first Linux Distro I β€œreally” used. Before that I sometimes used Knoppix to disable some time limits on my PC my parents set me (but that’s another thing). I used Ubuntu to revive some old PCs I got from school, including my first laptop. Ubuntu is the distro most people start their Linux journey with, wether it’s on the desktop or a server.

Why I Moved My Server To RancherOS

Containers are wonderful and Docker is a really awesome and lifesaving technology, even if you don’t host sites and services with millions of users that need to auto-scale etc. Docker can already simplify a simple hosting setup just with a couple of small webpages and a Git server.

Back To Static - And How I Made Forms Working

I used Pagekit for quite some time with my personal homepage. Pagekit gave me a nice Admin UI and there were also nice themes and plugins, which I could use. But Pagekit is PHP and the setup isn’t that optimal. So I switched back to a static site setup with Hugo.

Run Debian Based Programs On Almost Any Linux With Docker

Published on in πŸ‘¨β€πŸ’» Dev

I’m a Solus user (and enthusiast), but as one I also faced a common problem. Not every desktop app is available on Solus Linux and you also can’t run .deb or .rpm installation files, because Solus uses a different package manager and isn’t based on any other Linux distribution.

When you publish websites, write blog posts and make them available on the internet, it’s not uncommon, that you also want to get statistics about how many people read your stuff, how many people visit your website etc. And you also want to enable comments under your blog posts, giving people an opurtunity to ask questions or just leave a reply.

For the Paranoids: Install Your Own Firefox Sync Server

Published on in πŸ‘¨β€πŸ’» Dev

Many people use Google Chrome, because they like it’s fancy syncing feature. You know, open a tab on your PC and just continue on your phone. Or because of the nice built-in password manager. Just save that damn password and it’s securely stored in your Google account and available everywhere.
