[EN] Lightning talks: Codespaces and Git techniques

This time we're going to get two lightning talks - both around 20min, but somewhat open ended as always.

First one is Sia with Visual Studio Codespaces, second one will be by @kjellski about Git techniques to spice up your code versioning.

1. Visual Studio Codespaces
   To Be Done

2. Git to your advantage
   I'll get you through the easy parts with `git rebase --interactive` and we'll see how far we get through with a bit of advanced techniques in the end.

We'll try to keep it short, but in this format we can leave the end open - we hope to see you there :)
