Call for Lightnings...

9 February 2011

Do you remember Java Underground on JDD in 2008? It was start of my "creative" approach to knowledge sharing and first time when Polish Java community experienced lightning talks. It was very well received and I would like to give it a second chance during 33rd Degree conference. It is Conference for Java Masters, so I am expecting a lot of proposals coming from you. It is your chance to show up in the crowd of the top Java guys in Poland.

Rules are simple. You have got 5 minutes and nothing more. You need to present your idea in 300 seconds. And yes, it is doable. What is really great about lightning talks is that there is no time for, let's call it, "not important information". Be precise, be funny, be remarkable. That's the golden rule to the best lightning talk.

We are waiting for your proposal till 1st March. Send it to our email account.
