Spotkanie PJUG - Reactive web services and Functional Java - introduction

Our next Polish JUG meeting is going to happen on 27th of June 2017 at 6:00 p.m.

We will meet in the Guidewire Software (https://www.guidewire.com/pl) at Prądnicka 20a, Kraków. Be sure to check theirs meetup (https://www.meetup.com/pl-PL/Guidewire-Krakow/) as well.

Great thanks for sponsoring!

This time we will have a pleasure to listen to two presentations:

1. Kamil Szymański - Reactive web services

2. Łukasz Biały - Functional Java - introduction

Reactive web services

Ahh, reactive, probably the buzzword of 2017, newer and shinier than good ol' microservices, all asynchronous, non-blocking and I've even heard some event-driven buzz around it.During this live-coding session we won't focus on the shiny nor on saving the world with dataflows using composable operators.Instead we'll focus on how the execution of this reactive approach differs from 'classic imperative approaches' and check how it impacts resource consumption and tps.We'll also see backpressure in action, cover the topic of reactive converters (e.g. JSON encoders and decoders) and check a couple of libraries, both new and old ones, that help build reactive web services.

Functional Java - introduction

Functional-oriented programming languages are becoming more and more popular. Can Java developers gain anything from embracing the functional hype? In my talk I'll try to show that it's worth to incorporate functional idioms into your codebase to achieve greater type-safety, compile-time error detection and composability by using Java 8's lambdas, functional interfaces, language- extending libraries like Javaslang and functional-reactive programming library Rxjava.
