What we’re about
We like the JVM!
We're a Kraków based group of people who love to program on the JVM.

See all- Polish JUG meeting: Asynchronous multi-stream processing and Project LoomBrowar Lubicz, Kraków
We invite you to the next Polish JUG meeting on Tuesday, November 19, 2024, at 6:00 PM to Browar Lubicz (Lubicz 17J Street, Krakow).
This time, we have two speakers:
- Jakub Sawicki, Lead Software Engineer at HERE Technologies, will present "Asynchronous multi-stream processing in a distributed production environment – solution in Scala using Akka".
- Krystian Zybała a Java Performance Engineer, specializes in building low-latency, high-efficiency solutions will talk about "Here Comes the Loom: The Concurrency Will Never Be the Same Again".
This event is sponsored by HERE Technologies, the world's leading location platform company.
Snacks, drinks, and prizes will be provided as always ;-)
Don’t miss this opportunity to meet with fellow developers!
See you there!HERE Technologies is a location data and technology company that created the first digital map over 35 years ago. Today we are the world's leading location platform company with a global footprint across 52 countries. We have a strong presence in the automotive industry, and we also work with leading companies across a wide range of industries, including transport and logistics, mobility, manufacturing and retail and the public sector.
Jakub Sawicki is a software engineer with industry experience mostly in the JVM ecosystem, with an extra interest in creating resilient, scalable architectures. Currently working for HERE Technologies in Kraków making maps, with a history of raster satellite data management and AI research in global optimization methods.
Abstract about the talk:
A history of a component handling multiple heterogenous streams of data and its landscape. He will talk about aspects of the system which handles spatial data, and how it plays with having appropriate data semantics, akka/pekko and distributed design patterns.Krystian Zybała works as a Java Performance Engineer where he programs on a daily basis, creating low-latency solutions in cooperation with the JVM. He advises, trains, and helps in building various solutions where efficiency is necessary. As a hobby, he looks under the hood of the JVM and tries to get to know and understand it.
Abstract about the talk:
At a time when Herb Sutter announced to everyone that the free lunch is over (The Free Lunch Is Over A Fundamental Turn Toward Concurrency in Software), concurrency has become our everyday life. A big change is coming to Java, the Loom project, and with it such new terms as "virtual thread", "continuations" and "structured concurrency". If you've been wondering what they will change in our daily work whether it's worth rewriting your Tomcat-based application to super-efficient reactive Netty, or whether to wait for Project Loom? This presentation is for you. I will talk about the Loom project and the new possibilities related to virtual wattles and "structured concurrency". I will tell you how it works what can be achieved and the impact on performance.
