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

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.

Talks

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).

Lessons learned

Without further ado, here are the learnings:

  • When doing a live demo during a talk, always have a plan B.

  • Getting up at 6 sucks and Groningen is a long way from Arnhem.

  • Calling your dad in the middle of the night is fun.
  • Beer is good

All talks were recorded. These videos will be published shortly, probably at the PyGrunn Youtube channel.
