What we learned at PyGrunnX

We attended the 10th edition of PyGrunn, a Python (and friends) conference in Groningen, NL. Here's what we learned.

PyGrunn is a conference about the Python programming language and its uses. It is also about related subjects, hence "and friends". As this was the 10th edition, it was dubbed PyGrunnX.

It was a great experience to be at a real live conference again. Discussing stuff with others, meeting with ex-colleagues, making new contacts and sharing knowledge, we've missed it.


To get an idea about the diversity of subjects, have a look at the schedule.

Coen spoke about live blogging with Wagtail Live.

Kees spoke about better code reviews (slides).
