Hi… For starters I will list some of the events I will (or might) be going to:
- linuxday.at (a small very cozy Linux Event in Austria near the borders to Germany and Switzerland)
- linux presentation day (a huge amount of events spread through quite a bit of Europe during mostly the same day)
- Chaos Communication Congress, Leipzig, Germany (https://events.ccc.de/tag/34c3/ - probably no more tickets, but arguably the greatest event in the world )
- Chemnitz Linux Days, Chemnitz, Germany (one of the biggest Linux events in Germany)
- FOSDEM, Bruxelles, Belgium (see Wikipedia)
In any case you can ask me t show you around.
