Is it possible to show 7 languages in a 90 minutes presentation? In this session, I will give that a try.

I'm below average when it comes to typing. When typing in front of an audience, it's even worse.

Since I don't want to bore my audience, I'm going to use git commits as slides. For this, I'm introducing two new git aliases: git next and git prev.

To start the presentation: git checkout demo-start To move to the next step : git next To move one step back : git prev

To configure these aliases, run these scripts: git config --global alias.next '!git checkout git rev-list HEAD..master | tail -1' git config --global alias.prev 'checkout HEAD^' for moving within a specific branch: git config alias.next-j '!git checkout . && git checkout git rev-list HEAD..java | tail -1' git config alias.next-c '!git checkout . && git checkout git rev-list HEAD..csharp | tail -1' git config alias.next-e '!git checkout . && git checkout git rev-list HEAD..elixir | tail -1' git config alias.next-f '!git checkout . && git checkout git rev-list HEAD..fsharp | tail -1' git config alias.next-js '!git checkout . && git checkout git rev-list HEAD..javascript | tail -1' git config alias.next-r '!git checkout . && git checkout git rev-list HEAD..ruby | tail -1' git config alias.next-s '!git checkout . && git checkout git rev-list HEAD..scala | tail -1'
