GeeCON has expanded to Prague and on Oct 19, 2016 I had the pleasure to do an initial keynote talk. Dear GeeCON thanks a lot for such a wonderful experience.
Here is a picture taken just before my keynote started. I remember the moment as I was sitting just next to the photograph on left.
I talked about Graal and Truffle and I believe my talk was influential - certainly the next day talk about internals of Truffle by OracleLabs's Jan and Jakub was well attended as well.
It is so comfortable when a conference like GeeCON moves to the town where one lives! Enough to jump on metro and in thirty minutes I can be at the venue. Looking forward to next GeeCON.
