A few weeks ago I stumbled upon the game engine Godot and I decided to give it a try by learning how to use it for creating a 2D platform game. This blog post contains a walk-through of the different parts of this endeavour. The source code for my game is completely free and is available from GitHub so just go ahead and download and experiment with it as you like.
My kids are occasional Minecraft addicts. As I want to support their creative activities, I have setup a Minecraft server at home so they can collaborate with friends on their construction endeavours. The system we use is a Raspberry Pi 3 with a Spigot Minecraft server. A few weeks ago I had an SD-card corruption so I had to start from scratch with a new Raspbian OS install and setup the Minecraft server once again. This time I have decided to write down the installation- and configuration steps if someone else needs them.
