Slides for https://skillsmatter.com/meetups/10901-java-in-the-21st-century-are-you-thinking-far-enough-ahead . Java 9 arrives, JEE goes to Eclipse, IBM open sources Liberty & J9. Much is happening but so much more is to come. See how new hardware & software are powering Java to a life far removed from that originally envisioned It is all change in the Java arena. Java 9 ships with the long awaited modularity support. Oracle's contribution of Java EE to the Eclipse Foundation and to top it all, IBM announces both Open Liberty (based on its flagship application server ) and OpenJ9 it’s enterprise proven Java Virtual Machine. In this talk you’ll certainly learn about these exciting changes that are happening to the Java ecosystem but you also learn much more about the real future of Java. See how new hardware technologies, new software approaches and new ideas are powering Java towards a life far removed from that envisioned at its inception. It’s time to look up and see how you will need to change how you think: Whether it’s driven by AI or Quantum Computers the problems of tomorrow demand new approaches and new thinking. Are you ready?

One of the hottest question people are asking when they want to build an App is : “should I go for an hybrid or a native App ?”. At first hybrid looks very promising as it theoretically allows you to write code only once and run it in all platforms : iOS, Android, etc… But the reality is different and hybrid Apps usually end up being bad, even very bad. In this 45min. workshop, Olivier Berni, co-founder and lead UX at Lunabee will give you 5 reasons why native are far superior and really worth writing a bit more code. Olivier designed all of Lunabee's Apps including oneSafe, focusing on every UX and UI details, since 2010. Olivier has run many “UX experiences" for Lunabee Apps, iterating to try to find the right recipes to increase retention.

Using Flink to inspect live data as it flows through a data pipeline One of the hardest challenges with authoring a data pipeline in Flink is understanding what your data looks like at each stage of the pipeline. Pipeline authors would love to answer questions like ""why is no data coming through my filter?"" Or ""why did my regex not extract any fields?"" Or ""is my pipeline even reading anything from Kafka?"" Unit and integration testing pipeline logic goes a long way, and metrics are another great tool to understand what a pipeline is doing, but sometimes you need the data itself to answer why a pipeline is behaving the way it is. To answer these questions for ourselves and our customers, at Splunk we created a simple yet robust architecture for extracting data as it moves through a pipeline. You'll also learn about our implementation of this architecture, including the lessons learned while creating it, and how you can apply this architecture yourself. You'll hear about how to rewrite your Flink job graph at job submission time, how to retrieve data from all the nodes in the job graph, and how to expose this information to a user interface through a REST API.

In his book, The Nature of the Physical World, Sir Arthur Eddington commented that “We have to appeal to the one outstanding law — the second law of thermodynamics — to put some sense into the world.” This sense-making goes beyond the physical world, too. Entropy is also essential in the fields of information and communication theory. During this lecture for the Princeton Plasma Physics Laboratory, lecturer Andrea Goulet discussed the application of entropy-related concepts in two communication systems: software and collaborative teams. She examined how concepts that help us understand systemic statistical disorder, such as ergodic systems, Lyapunov exponents, Kolmogorov-Sinai entropy, and Shannon-entropy can help us optimize for both software quality and innovation. She also provided several domain-specific models: Lehman’s Laws and Conway’s Law for software, as well as new models from her own research that relate to entropy and innovation. Entropy helps us understand the world and achieve great things. There is an underlying beauty in its principles that we can use to advance scientific discovery. When we understand the subtleties related to balancing surprise and structure, we increase our chances for effective collaboration and finding novel solutions to complex problems.

Building a notification campaign might seem easy and it is easy to get started with a simple set up. But once the scale kicks in, it becomes every important to have a resilient architecture that can handle hundreds of thousands of recipients. This talk will focus on the Serverless services consumed in building the architecture and the various architectural decisions. The talk covers the various challenges in building an architecture of this sorts and how we overcame them using Serverless services.

The Mythical Technical Debt (Brooke, please, forgive me.) <This talk is designed for a technical audience> In software-intensive systems development, we often face trade-offs between speed and long-term maintainability. These trade-offs accumulate as technical debt, the hidden cost of short-term decisions that can impact future development. Technical debt goes beyond the initial choices made when creating software. It encompasses design decisions, coding practices, or anything that might hinder future development efforts. By effectively identifying and managing this debt, we can build robust and scalable software systems. In this talk, we'll explore different types of technical debt and their impact on projects. We'll delve into practical methods to identify, measure, and reduce it. Finally, we'll see how to turn technical debt into an advantage, using it as a springboard for innovation with real-world examples.
