Use Telegram as a notification service with Go

Published on in 👨‍💻 Dev

Telegram is my favorite messenger for chatting. There are many reasons for this. But Telegram is also very suitable to use it as a notification service for your own projects.

How to Get a Completely Free Website

Published on in 👨‍💻 Dev

In this post I want to show with which services and tools it is possible to run a completely free website. An own website not only offers the possibility to create your own professional web presence, it can also make you independent from silos like Facebook, Twitter or Medium.

Migrate a PostgreSQL Container to a New Major Version

Published on in 👨‍💻 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.
