Currently I am working for CSS Versicherung in Luzern. I am Java developer during the days and Scala\/ScalaJS at nights. I like to present my experience in public \u2013 so far speaked at conferences such as Devoxx, Voxxed Days, JUGs, Geecon, JdayLviv etc. I like to do shows &#8211; presenting the things just as they work \u2013 with live coding, demos and hacking.<\/span><\/p>\n<\/blockquote>\n<p class=\"p1\"><span class=\"s1\">What does it mean\u2026 Lambda?

But what does it mean\u2026 Lambda? The talk will be about story behind this term, from a little bit more scientific point of view. Church Lambda calculus, Entscheidungsproblem and incompleteness theorem. Almost all of that will be presented in Java \u2013 in the language that you understand. And of course you can later impress your friends with some impressive math tricks. There are going to be shown some very crazy code pieces such as perfectly unusable implementation of boolean (based on lambda expressions). Come and see what purely functional really means.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Lambda Core HardCore Jarek Ratajski is a Java Developer since 1999.
