Thoughts after JCrete unconference

I don't always write conference reviews. But when I do, they are about awesome ones. And JCrete was truly awesome. I got invited by Heinz Kabutz himself and this is pretty much the only way to get there. JCrete is an uncoference with no tickets and no designated speakers. Besides there is no conference fee but also everyone pays for themselves. This feels a lot more like a group of people meeting each other informally rather than a full-blown, very official conference. Which is good. Few people won an invitation in an open draw but most of the guests are selected by the organizers. This means you are guaranteed to meet fantastic people from Java community, dozens of Java Champions and open source contributors. This year's attendees included Cliff Click, Richard Warburton, Kirk Pepperdine, Stuart Marks, Jonas Bonér, Viktor Klang, Dan North, Ken Sipe and Stephen Chin. And of course Heinz. A lot of great people to meet and share experiences.

But JCrete is an uncoference, meaning there are no speakers and agenda. Every morning we met and decided what we want to talk about today. In practice everyone could stand up, suggest a topic and put it on a post-it. Once all suggestions were done we gathered in front of the board and decided which topics should be covered and where. Typical uncoference style. What was unusual was the venue. Orthodox Academy Of Crete is located close to the beach in Kolympari on the beautiful island Crete. One of the ad-hoc tracks that we built every morning was named Beach and was hosted literally on the beach. The only caveat of the OAC was poor WiFi, but that's something almost every single conference struggles with. But do you really need WiFi when the view from your hotel room's balcony is like this?


JCrete lasted for 5 days and our daily routine was pretty similar. We woke up, have breakfast and came together to select talks for a given day. Talks were up to 1 hour and we selected no more than 3 talks per track. You might think that a week long conference with just 3 hours of talks is quite a lazy schedule. And you are right! After talks we went for a lunch and every day ride to a different beach. Having a car is essential during JCrete but people are happy to share a ride. This is where the real joy begins. You drive with "strangers" for few quarters or an hour, being encouraged to always go with different people. It means every day you have an opportunity to talk to Java professionals from all around the world (seriously, there were people from Australia!) And once you are there, at the beach, more discussions pop up. I'll never forget Kirk Pepperdine standing neck-deep in the water and explaining Java 9 GC logging intricacies. On this beach:



Another day I went to the nearest town with a bunch of attendees to have a dinner. Once again we ended up talking for hours about LMAX in the banking industry. JCrete is not just a wonderful vacation opportunity (as a matter of fact many people came with their families). It's a social event with the best networking opportunities I've ever seen. I guess it comes from the mixture of great people being invited (many of them awarded Java Champions), fantastic cuisine and wonderful location. Oh, did I mention that the food was great? Most of the time we had a dinner together with like a dozen of different dishes to try.

The quality of the tracks was also exceptionally good. Oftentimes I found it hard to pick good talks on normal, commercial conferences. But at JCrete every single session was inspiring and worthwhile. I'm not exaggerating, on some conferences I'm recently getting bored but JCrete was way more enjoyable. Well, I tried to attend Cliff Click's talks twice, but all I saw was a wall of assembly so I gave up ;-). But such in-depth talks are something you won't see on ordinary events. I proposed and gave three talks myself: about reactive programming (focused on RxJava), asynchronous architecture patterns (event sourcing in disguise) and HTTP/2. I'm far from an expert regarding HTTP/2 protocol but I gathered few people that were more experienced and I learned a lot. Here's me doing some live coding as captured by Heinz:



Overall JCrete is one of the best Java events I ever attended. If you are looking for an active vacation together with your spouse and children, this place is great. If you need a Java event with a very strong line-up and networking capabilities, JCrete has it all.
