"Java 8 is one of the most highly anticipated programming language updates in many years. Let me give you an introduction about its new features: Lambda expressions, Method references, Default Methods, Stream API, new JS Engine, new Date/Time API and more..."
Modern Programming in Java 8 - Lambdas, Streams and Date Time APIGanesh Samarthyam
This presentation provides a comprehensive overview of modern programming in Java. It focuses only on Java 8 features: Lambdas, Streams and Date Time API. It also briefly covers refactoring legacy Java code to Java 8.
Functional Thinking - Programming with Lambdas in Java 8Ganesh Samarthyam
Functional programming is on the rise. Almost all major and mainstream languages support functional programming features, including C++, Java, Swift, and Python, and Visual Basic. With Java 8’s lambda functions, Java now supports functional programming. Moving to functional programming can result in significantly better code and productivity gains. However, it requires a paradigm shift: you need to move away from imperative and object-oriented thinking to start thinking functionally. That’s what this workshop will help you achieve: it will help you make your shift towards functional programming. The workshop will introduce lambda functions in Java with examples from Java library itself. Presented in OSI Days 2015 workshop - http://osidays.com/osidays/shifting-to-functional-programming-lambdas-for-java-developers/
Java is Object Oriented Programming. Java 8 is the latest version of the Java which is used by many companies for the development in many areas. Mobile, Web, Standalone applications.
Java 9 introduces modules to the Java programming language and its runtime. Despite this feature being optional, due to the modularization of the standard library existing applications might behave differently when running on a version 9 JVM. Furthermore, because of changes in the runtime, existing libraries and frameworks might not yet correctly process your modularized code. As a result, updating to a Java 9 VM and taking Java 9 into brings its challanges.
This talk discusses the practical implications of module boundaries and analyzes new limitations Java 9 imposes on the reflection API. This talk explains how reflection is used in popular frameworks like Spring and Hibernate and explains why existing applications might break or change their behavior when facing modularized code. Finally, this talk showcases alternatives to now failing Java programming patterns and weights their robustness with regard to the Java releases 10 and upward.
The presenter is an active contributor to open source and helped to migrate many popular Java libraries to supporting Java 9. As a consequence, he as been working with Java 9 for almost two years.

Understanding bytecode and what bytecode is likely to be generated by a Java compiler helps the Java programmer in the same way that knowledge of assembler helps the C or C++ programmer. Java bytecode is the form of instructions that Java virtual machine executes. This knowledge is crucial when debugging and doing performance and memory usage tuning. The presenter will share his knowledge on what bytecode means for your platform and how to create compiler while using some awesome tools.
Quality assurance and testing are very important in a life cycle of any application. Although, by far not all developers understand the significance of tests.
In this presentation, we cover the basic testing practices for developers. The following tools are discussed: JUnit, Mockito, Hamcrest, JsTestDriver, DBUnit, Arquillian, SoapUI, Selenium.

Then show you the ones you never had time to look at in 9, 10, 11, 12 and 13.
And go crazy to check how it’s implemented under the hood (yes, there will be bytecode).
PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
