One of the buzzwords that you have likely heard (or experienced) in the past few years is all about XR: Augmented and Virtual Reality. These innovations are driving us into developing new ways on how people can meet up, knowledge can be shared and immerse us into entirely new experiences. And best of all, thanks ot the WebXR API, we can do this in a browser! In this lightning talk, I want to highlight how much is (and isn't) already possible with just Javascript(and HTML!), and how we can transport our users into new worlds or add virtual objects into their own environment.

In this talk, I'll go over some code smells and show how to remediate them. Java will be used to show the refactoring but it's valuable for developers of all programming languages. Don't expect to see slides, all coding will be done live.

In this talk you’ll learn all about Serverless concepts, application of serverless in industries, needed skill set, partner integration(DevOps challenges). Finally, how much will it all cost you end of the month?

Dark Mode on the Web: In this session, you’ll learn why Dark mode is becoming increasingly popular across platforms. Let’s see why themes are important for users, how we can implement them on the web, and what is needed from UX and design.

Data Science: Expectations vs Reality: Given all the attention the field receives in the media, many developers are interested in learning more about Data Science or Machine Learning. As someone having made the transition from being a complete novice to working on code that involves state of the art NLP running on GPU clusters we like to share what you can expect when you work on Data Science projects in the real world versus what is taught in online courses.

Today’s CoreData: Usually, when thinking about persistence in computer science we implicitly bring the idea of an old monolithic infrastructure which implies a lot of tedious tasks just to store some pieces of data related to our program, this was not different for iOS so Apple decided to create a dedicated object graph framework to help in this regard, but still, it was not so easy to apply. With the release of Swift the framework got push forward but the “old mindset” made that it was not easy to be adopted. This talk tries to provide a foundation that helps to understand and use Core Data in modern applications both in SwiftUI, and in UIKit. We will be able to understand the key concepts of Core Data, build an app that fetches and displays data and get familiar with more advanced topics.

Making decisions is impossible without knowledge, and knowledge is obtained from information that evolves from data. While the classical “data warehouse” approach focuses on taking all available data into account, the “streaming” approach is centred around the idea of reacting to events as soon as possible, extracting all the knowledge necessary for decision making “on the go”. Kafka stands out from other message brokers because it’s not a message broker - it’s a streaming platform originating from LinkedIn, a platform well known for its fast-paced communication dynamics. In this presentation you will learn about Kafka, Kafka-Connect and Kafka Streams and dive into a practical example of using Kafka Streams DSL on a real data stream and Python scripts will help to provide input and interpret output to/from a Kafka cluster.

Collaboration process between designers and developers has been long overdue for a revision. The current version of it, essientially built around designers handing off static images with annotations to engineers, is wasteful and inefficient. We will talk about how modern design tools that embrace web standards can revolutionize this process.

Arthur C. Clarke once said: “Any sufficiently advanced technology is indistinguishable from magic” The first time I used Shazam (the music matching app) it felt just like that: pure magic. The app shortly listens with the microphone and tells you which song is playing. As a programmer I generally have a pretty good understanding of what happens behind the scenes, in this case, however, we were absolutely gobsmacked. After a weekend of studying, reading scientific papers and experimenting and coding: we had a working Shazam clone written in Java. During this talk, we’ll reveal what we’ve learned and what algorithms and tricks are being used.
