JVM Armageddon

At the very beginning of the last month of 2015 we had a pleasure to listen to very experienced speaker - Jaroslaw Palka @j_palka - who told us many interesting facts about JVM internals.

So we had a chance to see some parts of JVM source code where exceptions are literally swallowed and hear stories about debug sessions "till 4 A.M."

Haskell Continues

This time on Haskell Workshops Artur Czajka @tr00per87 was teaching about Functors, Monads and Monad transformers.

Haskell is a very good way to learn Functional Programming - more people should try it

For the first time in Lodz - Security Workshops

And for the first time in Lodz we had a workshop about general topic of applications security. Marcin Mela from HARMAN give us many examples how insecure web applications can be, which cryptographic function is safe and how easily it is to find on google someones private cameras streaming live content!

In the second part we had one hour to hack small web application and find all security holes.

Spark & Dataframes

We also had a chance to learn about "bridge between Programming and Data Science" - Dataframes - during workshops prepared by Paweł Włodarski @PawelWlodarski
