A Dozen Cool Things You can Do with JVM Languages
- Venkat Subramaniam
10:30 - 11:20
Room: 500/1-001 - Main Auditorium Languages offer a lot more than syntax and compilers. They often have supporting libraries and special facilities that set them apart from other languages. Some languages offer special compiler support for a particular construct, like tail call optimization, for example. Others provide interesting library support or capabilities. In this presentation we will dive into 12 cool things we can do with different languages on the JVM, things that are either impossible or hard to do in Java, but are quite easy and useful to realize in other popular languages on the JVM. If mixing these languages is an option on your projects, you’ll have dozen more reasons after this presentation.
The Importance of Fun in the Workplace - Holly Cummins
The Importance of Fun in the Workplace
- Holly Cummins
10:30 - 11:20
Room: 503/1-001 - Council Chamber An in-depth look at what makes software development a roller coaster where the highs of 0 compiler warnings are quickly cancelled out by the pain of long hours, bad requirements, endless configuration, clueless managers and a plethora of other issues which make death by a thousand cuts seem like a good idea…. They will answer questions such as: “Why is programming often called an art despite having its underpinnings in formal logic?” “How can I rediscover the delight I felt when I first started coding?” “What’s that rush I feel when my test passes? Am I addicted to TDD?” Combining Psychology, Philosophy and Computer Science, Dr Holly Cummins will present a series of practical tips to help you rediscover the euphoria that you felt the very first time a metal box in front of you came to life and cried out “Hello World”.
11:30 Bulletproof Java Enterprise Applications for The Hard Production Life - Sebastian Daschner
Bulletproof Java Enterprise Applications for The Hard Production Life
- Sebastian Daschner
11:30 - 12:20
Room: 503/1-001 - Council Chamber It’s one thing to develop Java Enterprise applications, to execute, and validate them in test environments. Running the application in production, however, is a whole other story. Production life is harsh, unforgivable and the ultimate verification whether your application is able to add value to its users. Besides knowing the Java Enterprise APIs, developers therefore also need to know how to meet production requirements. This session shows which non-functional requirements we enterprise developers need to be aware of to build stable and resilient applications. We will see different resiliency approaches, such as circuit breakers, bulkheads, or backpressure, in action. We will implement these concepts using the Java Enterprise API, MicroProfile, and certain Java EE extensions. Furthermore, we will see, how especially service meshes enable us to add resiliency to multiple microservices in a transparent, redundancy-free fashion. Adding telemetry to our applications is crucial to gather insights about the application under production load. We will see how to enhance our microservices with concerns such as monitoring, tracing, or logging in a minimalistic way.
The Error of our Ways - Kevlin Henney
The Error of our Ways
- Kevlin Henney
11:30 - 12:20
Room: 500/1-001 - Main Auditorium What happens when things break? What happens when software fails? We regard it as a normal and personal inconvenience when apps crash or servers become unavailable, but what are the implications beyond the individual user? Is software reliability simply a business decision or does it have economic, social and cultural consequences? What are the moral and practical implications for software developers? And when we talk of ‘systems’, are we part of the ‘system’? What about the bugs on our side of the keyboard? In this talk we will explore examples of failures in software and its application, and how they affect us at different scales, from user to society.

Modern Java: Change is the Only Constant
- Mark Reinhold
13:30 - 14:20
Room: 500/1-001 - Main Auditorium In the past two years, we changed Java in three ways that we never have before: We modularized the platform, we removed some components, and we accelerated the pace of new releases. These changes aim to keep Java vibrant in an ever-changing world of competing platforms and new styles of application deployment, whether to the cloud or to app stores. We’ll see why these changes are not as disruptive as you may think, and demonstrate some of the recent and future additions to the language and the platform.
Unleashing your musical creativity with Magenta.js - Monica Dinculescu
Unleashing your musical creativity with Magenta.js
- Monica Dinculescu
13:30 - 14:20
Room: 503/1-001 - Council Chamber People make things. You make things. Most of the time you make Very Serious Things™️ that help your bosses sell more shoes or saxophones or those tiny coffee packets. And that’s good, because you gotta eat and stuff. But something else has gotta eat, too: your brain. Music is creation, art is creation, code is creation. I think it’s important to goof around with code sometimes, or make things that let other people goof around with code. And sometimes, that becomes the Very Serious Thing™️. Magenta.js is one of these things; let's talk about it!

- Cagatay Civici
14:30 - 15:20
Room: 503/1-001 - Council Chamber Progressive Web Applications or PWAs in short, utilize modern Web Technologies to create cross-platform applications that offer the best of web and native user experiences. This talk begins with the introduction of the PWAs, advantages over the legacy approaches and covers the core elements that define a PWA accompanied by examples with popular libraries like Angular, React and Vue.

14:30 - 15:20
Room: 500/1-001 - Main Auditorium When we look at the world our brain instantly turns the images we see into information, intuition and feeling. It does so with an enormous computational effort, using a network with overwhelming, unexplored architecture. We are not even close to create a machine of comparable capabilities, but step by step, improving both the hardware and algorithmic approach, we can make machine understand images they see. In this talk you will learn how to design and develop such a network. We will go from the basic machine learning concepts, through the advanced practical tips, up to using the most-recent state-of-the art architectures in practice. You will see examples on how insanely complicated problems can be solved using a portable computer. And in the meanwhile you will understand what is going on, why new layers are added and why new concept have to be introduced. While this presentation briefly introduces all the basic concepts, as we move on it quickly touches advanced and expert areas of the field.

Deconstructing Web frameworks for a more resilient code base
- Hubert Sablonnière
15:50 - 16:40
Room: 500/1-001 - Main Auditorium In the wonderful world of frontend Web, the frameworks and their ecosystems come and go… For a lot of devs, this endless race is getting tiring. Nevertheless, we continue to make architecture decisions that will push us tomorrow to throw away and rewrite lots of code. Step by step, it gets very easy to be locked into a given framework/ecosystem and too easy to limit one’s skills to what this ecosystem provides. We tend to forget the basics and most of the time it pushes us to write code where all layers and concerns are mixed up (UI, DOM access, data access, router, stage manager, bundling, build…). In this session, we’ll deconstruct the different parts of modern Web frameworks : Why are we using those tools? Which problems do they solve? How can we avoid our code to be locked in and mixed up with those ecosystem? How can we produce future-proof code that resists against the hype and evolutions of the Web platform?
Interaction Protocols: It's all about good manners - Martin Thompson
Interaction Protocols: It's all about good manners
- Martin Thompson
15:50 - 16:40
Room: 503/1-001 - Council Chamber Distributed and concurrent systems can be considered a social group that collaborate to achieve collective goals. In order to collaborate a system of rules must be applied that affords good hygiene, fault tolerance, and effective communication to coordinate, share knowledge, and provide feedback in a trusted manner. These rules form a number of protocols which enable the group to act as a system which is greater than the sum of the individual components. In this talk we will explore the history of protocols and their application when building distributed systems. Protocols provide the foundation on which the quality attributes are delivered. Qualities such as performance, resilience, and security.
16:50 Recursion, Iteration, and JavaScript: A Love Story - Anjana Vakil
Recursion, Iteration, and JavaScript: A Love Story
- Anjana Vakil
16:50 - 17:40
Room: 503/1-001 - Council Chamber Recursion and iteration usually seem like epic rivals, on opposite sides of a fundamental tradeoff between machine- and human-efficiency. Iteration's stateful repetition can be more performant, but many coders prefer to work with the self-referential abstraction of recursion. But in this talk we'll see that with a little love from JS, these apparently star-crossed paradigms can actually unite to improve each other: custom Iterables allow recursion to power more human-efficient iterative code, and tail call optimization uses iteration to make recursive code more machine-efficient.
Transform a Legacy Application with Kubernetes and Istio - David Gageot
Transform a Legacy Application with Kubernetes and Istio
- David Gageot
16:50 - 17:40
Room: 500/1-001 - Main Auditorium Kubernetes is often used to run micro-services based applications. Istio’s service mesh adds even more power and flexibility to those applications. But what about your Good Old Monolithic Legacy Application? Should you feel left alone if you’re not cloud-native? I’m going to demonstrate how to leverage Kubernetes and Istio to improve an existing application without touching a single line of its code. Because, you know, the original developers are long gone. Through lots of demos and zero slide, the attendees will learn to add Monitoring, Blue/Green Deployments, Canary builds, Fault tolerance…
