Chopping the monolith
Micro services are ubiquitous. However, most companies that implement micro services do not reap their full benefits - at best. At worst, it’s an epic failure.

Powerful Java problem determination methods
While every software has a unique way of how anomalies manifest and how those are diagnosed, there is a common philosophy that governs a series of connected logical reasoning and steps that originates from that reasoning - forming the basic blocks of Java problem determination. On a real debugging scenario, these high level philosophy is interpreted and customized for the actual problem context. In this session, we examine the governing principles of Java problem determination and how this applies to root cause analysis exercise, with the help of case studies and real world examples.

Give your application memories
Most applications only know the present. Their current state is calculated and updated somewhere on every change, effectively losing any previous states and information that only existed in the past. Can that be a limitation? Missed opportunity? What if your application could remember its entire history? Would that be any helpful, or is it a worthless effort? This talk will provoke Java developers to start asking such questions. It will provide useful mental models to better understand Event Sourcing, DDD, and CQRS concepts.

Location transparency (for Java developers)
If it is the first time you've heard the term, this talk is for you! This talk is definitely for you if you are concerned about Coherence, Coupling, and Connascence while building applications. The amount of things that can break prevents you from splitting a monolith into distributed micro-services? In that case, applying location transparency may be both your kick-starter and your safety net.

Deployment options for OSGi applications in the cloud/edge
There are different ways to deploy a Java application. Traditionally it was a single JAR or a collection of JARs on a machine that has a matching Java Runtime installed. Today there are additional formats like a custom created JVM via jlink or a native compiled Graal Substrate. This gets especially interesting when thinking about deployment of smaller applications for processing tasks via containers in the cloud or on edge devices.

OSGi.fx - Unleashing an OSGi console for modern era
OSGi is around for many years and is currently the de facto standard to build modular applications. It provides a long list of open specifications making it possible to define the dependencies of each individual module with others and enable users to control the lifecycle of the components in the system. External tools are still required for the runtime configuration and management of the framework and bundles deployed within it.

How to NOT build a parser for AsciiDoc markup
Some years ago I set out to build a lexer and parser for AsciiDoc to use it in IntelliJ for syntax highlighting and AST manipulations.
How hard can it be? Without knowing much about parsing, I extended an existing minimal JFlex parser, and gave it a try. This talk will revisit several problems I faced, and show when and how not to use JFlex.
