Reactive programming è un paradigma di programmazione basato sulla processazione asincrona di eventi. La sua cresente importanza è confermata dall'introduzione in Java 9 delle Flow API che definiscono un contratto che tutte le librerie di reacrive programming dovranno implementare. Lo scopo di questo talk è chiarire i principi del reactive programming definite dal reactive manifesto e formalizzate dalle Flow API insieme alle feature più avanzate di processazione, trasformazione e combinazione di eventi offerti da RxJava.

The future of e-commerce requires personalized content for each individual customer. With over 20 million active users, Zalando is facing the challenge of making its frontends more scalable in order to achieve this goal. We brought a solution from the backend to the frontend: microservices. In addition to creating Project Mosaic (https://www.mosaic9.org)—our solution for modular frontends—and using a toolbox of modern web technologies like React and Webpack, we built an architecture that can scale to virtually any size and even support targets other than the browser.

To say that a web application is fast or slow is a complex subject: several factors are involved, and several different metrics can be used to measure how it's performing. This talk will showcase different approaches to web performance measurement and different techniques that can be used to measure, track and optimize web applications.

Do you feel the JavaScript fatigue? Are you still trying to learn ‘the next big thing’? Does your code seem legacy just after six months because of that ‘next big thing’? Have you ever thought of building a software, even a complex one, without any kind of dependency on your package.json? During the talk, we are going to see how to create your own framework and libraries with just standard ECMAScript features and W3C standard APIs.

What if you could look at the source code behind any visualization, understand how it works, run it to check the results using the latest data and modify the parameters to explore different aspects of the data? I this talk, I will show how we used F# and functional programming to develop a new browser-based data visualization environment. I will show two fun projects that we created looking at the history of Olympic games and testing what people know about the UK government spending. Expect to learn about fun data science and programming challenges we encountered along the way!

Running Redis for 8 years what I learned about people and technology - Considerations about human and technological factors, learned on the field while creating, supporting and handling the community of the Redis database project.

What if someone told you that you could use the full capacity of your server? That you could have the same performance on the backend as your react frontend? Don't you believe it? That you could choose the best language/tool for the task and you were not limited by what you already know? In this talk, I'll show you that you can use the full power of React on the frontend and Vert.x on the backend. You will see a fast full stack development workflow with Rollup/Webpack + Babel + React. How you can mix JavaScript with any other language. Build microservice applications in minutes.
