Usually I do the review of what we do in our JUG, but Dmitry did quite a good job and he has the best pictures.
Some minor additions from me:
Venkat Subramaniam also known simply as Venkat was here. Venkat is a rockstar (JavaOne Rockstar is someone who did an amazing session at JavaOne. Venkat is 16 (sixteen!!!) times J1 Rockstar in just 4 years).
Venkat did two sessions and a workshop. The two sessions (one on lambdas and one soft-code session on bad code) were highly popular, probably 150-200 people came.
Then there was a workshop that turned into a discussion on lambdas and quality code in general. Which was awesome.
