Track 1
Java gears in Data Science
In recent years, many curious projects appeared that can make Java closer to data science. Among these tokens are interesting JEPs, experimental JVM features, open source libraries and projects from Oracle Labs.
We'll have a look on:
- how to accelerate vector math operations using SIMD,
- how to bring JVM together with GPU and perform general purpose GPU calculations,
- features of the "Tribuo" Java library created by Oracle labs for machine learning.

Track 2
Discussing Backend For Front-end
In the good old days, applications were simple. A browser sent a request to a webapp endpoint; the latter fetched data from a database and returned the response.
The rise of mobile clients and integrations with other apps upset this simplicity. I want to discuss one solution to handle the complexity in this speech.

Track 1
Java on CRaC: Superfast JVM Application Startup
One of the key benefits of a microservice architecture is the ability to dynamically respond to changes in load by spinning up new instances as required. However, when deploying JVM-based services, the warmup time of JIT compilation can be a limitation on the effectiveness of this technique.
One approach to solving this problem is using native images, where the service is statically compiled using an ahead-of-time (AOT) compiler. Although this does reduce startup time and footprint, it does so at the costof overall performance.A new project has been proposed and accepted into OpenJDK called CRaC (Coordinated Restore at Checkpoint). The goal is to research the co-ordination of Java programs with mechanisms to checkpoint (snapshot) a running application. Restoring from the snapshot could solve some of the problems with the startup and warmup times, especially in microservices.In this session, we’ll look at the main challenges for such a project, potential solutions and the results from a proof-of-concept implementation.

Track 2
Unstuck it: Career development for senior engineers
Quite often, career growth stagnates when an engineer reaches a senior or lead position because there are no obvious positions to fit evolutionary, which could lead to job hopping.
How to keep valuable employees engaged and help with professional and personal development?Paths: engineering vs management- Using a framework- Extending your portfolio- Developing soft skills- Increasing visibilityWhen you are ready: next steps

#Workshop
Developing Reactive Microservices in Quarkus
Difficulty level: Middle+ • Limited seats • Free to attend
From Day 1 Quarkus has provided support for developing reactive microservices and this support has only been improved and refined over time. In this workshop we'll go through the steps necessary to develop microservices that are fully reactive, from the HTTP layer down to the persistence layer.

We learn something new every day and want to help others learn. That's why we decided together with the Caritas charity fund to collect 40 backpacks for little Ukrainians.
We delivered these backpacks to children from immigrant families and from families in need of financial assistance.
We collected 10 backpacks with the support of the Java Community 💪, and Luxoft donated the amount for another 30 backpacks.
You can steel join with any convenient donation — every UAH 5 is important. A link with the possibility to make a charitable contribution will be on the screen, as well as in a letter in the mail.
Everything will be Ukraine!
