The fifth meetup will be held by Developer Advocate at IBM, Mary Grygleski. She will present two talks, the second one featuring Software Engineer at Netifi Oleh Dokuka.

Reactive for the Impatient (A Gentle Intro).

This talk presents to the audience a few of the major Java-based reactive frameworks and toolkits in the market today, such as RxJava, Spring Reactor, Akka, and Vert,x. It will start by going over the basic tenets of reactive systems, and some examples of the problems that these systems aim to solve. It will discuss the 2 most commonly used Java frameworks for implementing reactive coding - RxJava and Spring Reactor, and will show some code samples. It will then bring the audience to the next level of "reactivity' by introducing 2 reactive frameworks - Akka and Vert,x, which are usually used for implementing reactive microservices. It will draw some comparisons between these 2 frameworks and cite some real-life examples of their usages.

Teach Your Pacman to play with ML and Reactive Streams (co-presentation with Oleh Dokuka).

Today the adoption of Machine Learning is enormous. We use it almost everywhere: on clusters, on our phones, on hand watches and even on the teapots. But, who knows how challenging could be the development of the continuously improved (or even real-time) machine learning. Servers' capacity, stability, performance, along with a proper ML algorithm selection and many other properties must be taken into account. In this presentation, we will be demonstrating bots education for multiplayer Pacman game. We will show how elegant could be the development of such a problem with Kafka, Akka, RSocket and ML Reinforcement Learning.
