Jarek Ratajski - Java Developer since 1999

I love programming since my first line of code I did on the C64 in Basic. Somewhere in 90ties I've switched from C++ to java and spent then 18 Years developing JavaEE software working for various companies and projects.

Now I work for Engenius in Switzerland being Java developer at banks during the days and Scala/ScalaJS open sources hacker at nights.

Beauty and the beast

Real haskell on a real JVM. With optimizations and lot of fun.

LOCATION: Luzern
KEYWORDS: Architecture, other Languages, Research

AGENDA:18:00 - 19:15h: Talk incl. Q/A
Afterwards you are invited to a refreshment.

SPEAKER: Jarek Ratajski   COMPANY: engenius GmbH
SLIDES: 180418_Jarek_Ratajski_Beauty_and_the_beast.pdf

After 20 years of evolution the Java Virtual Machine became a real masterpiece of engineering and can easily outperform static compilers in many cases. There are however a lot of issues arising when someone tries to use the JVM for functional languages. It is particulalry hard to create an efficient Haskell implementation for the JVM.

Developers of Eta tried it once again in a little bit different way. We will analyze how it works on a sample system, where the business logic is written in Haskell and middleware components and libraries in Java.

We will try to analyze when it makes sense and how does it compare to the pure Java/Haskell implementation in terms of performance and code quality.

LEVEL OF TALK: Intermediate
LANGUAGE: Talk: en / Slides: en
