ApacheCon Core: Service Discovery in OSGi: Beyond the JVM using Docker and Co...Frank Lyaruu OSGi offers an excellent service discovery mechanism, but it is limited to services inside the JVM. With Docker nowadays it is trivially easy to deploy all kind of (micro) services, using pretty much any technology stack, so we’d like to discover those as easily as the ones inside the JVM. We will have a look at how we can use the Docker API to discover services in other containers, and how we can use Consul to expand service discovery to other hosts.

From Rails legacy to DDD - Pivorak, Lviv
From Rails legacy to DDD - Pivorak, LvivAndrzej Krzywda Rails is optimised for the first weeks of development. At the later phases it's no longer the speed of adding new views and data that matters. It's often more about the different (and changing!) ways of using the data. The business logic gets more complicated.
DDD has answers to those problems. Detecting the bounded contexts is the crucial skill. Choose which parts of the app leave as CRUD and which could go into more of the tactical DDD.
Beyond The Rails Way
Beyond The Rails WayAndrzej Krzywda The Rails Way is the reason of Rails success. It's also the reason of Rails disappointment. Why is it so?

Better java with design
Better java with designNarayann Swaami This document discusses best practices for object-oriented Java design. It recommends learning design principles from books, conferences, and by analyzing code to see what works and doesn't work. Specific principles covered include the single responsibility principle, open/closed principle, Liskov substitution principle, interface segregation principle, and dependency inversion principle. Techniques demonstrated include using creation methods instead of constructors, replacing conditional logic with strategies, encapsulating classes with factories, and encapsulating composites with builders. The goal is to create well-designed, loosely coupled code that is easier to change and maintain.

From legacy to DDD
From legacy to DDDAndrzej Krzywda This talk was delivered at the PHPers meetup in Wroclaw, 10 August 2015.
I presented a set of techniques which help you transition from a legacy codebase to DDD. I focused more on the strategic DDD patterns like bounded contexts.
The main idea in such refactorings is to:
1. List all your (potential) bounded contexts
2. Decide which ones are deserving the DDD tactical patterns
3. Decide which ones can stay as CRUD
4. Communicate between the BCs via events

Zapping ever faster: how Zap sped up by two orders of magnitude using RavenDBOren Eini
Join a real uplift experience with Hagay Albo, the CTO of the Zap/Yellow Page Group in Israel, in which he explains how his team was able to take a legacy (slow and hard to modify) group of sites and make them easier to work with, MUCH faster and greatly simplified the operational environment.
By prioritizing high availability, flexible data modeling and focusing on raw speed Zap was able to reduce its load times by Two Orders of Magnitudes. Using RavenDB as the core engine behind Zap's new sites had improved site traffic, reduced time to market and made it possible to implement the next-gen features that were previously beyond reach.
Performance and Abstractions
Performance and AbstractionsMetosin Oy Tommi Reiman discusses optimizing Clojure performance and abstractions. He shares lessons learned from optimizing middleware performance and JSON serialization. Data-driven approaches can enable high performance while maintaining abstraction. Reitit is a new routing library that aims to have the fastest performance through techniques like compiled routing data. Middleware can also benefit from data-driven approaches without runtime penalties. Overall performance should be considered but not obsessively, as many apps do not require extreme optimization.
Continuous integration
Continuous integrationLior Tal Continuous integration involves developers frequently integrating code changes into a shared repository. Each change is then verified through an automated build and testing process to quickly detect issues. This helps ensure code quality by making the build and test process part of every code change. Key aspects of continuous integration include source control management, automated builds, and tools for testing and analyzing code quality.
AWS Lambda Function with Kotlin
AWS Lambda Function with KotlinTroy Miles Kotlin is a language from the tool gurus at JetBrains. In 2016, after about six years of development, Kotlin reached version 1.0. In 2017 it won the hearts of developers and became an officially supported language for Android.
Kotlin, like Java, is for more than creating Android applications. It can replace or enhance Java most places it is used today including on AWS. AWS Lambda functions sometimes called Serverless Computing, is a service which lets us developers build web services without worrying about configuring servers.
In this session, we will create a lambda service on AWS using Kotlin. Along the way, we will learn what a makes Kotlin an excellent replacement for Java and how simple it is to construct an AWS Lambda function.

Building occasionally connected applications using event sourcing
Building occasionally connected applications using event sourcingDennis Doomen I've recently got the opportunity to work on a large enterprise-class system that needs to be deployed on multiple occasionally connected oil platforms and boats. Already the system's architecture was based on the Command Query Separation principles, this gave us a completely new challenge. After several months of looking at alternatives, we decided to go the Event Sourcing direction. In this in-depth session, I'd like you to learn the many alternatives we observed, the pros and cons, and the technical details of our final solution in which we use EventStore 3.0 and elements of NCQRS and Lokad.CQRS to synchronize systems over unreliable connections in a very efficient way.

Open Source Dev Containers with DevPod - Rich Burroughs.pdf
Open Source Dev Containers with DevPod - Rich Burroughs.pdfRich Burroughs Many developers are excited about dev containers, but until now, people needed to use a managed service like Codespaces or Gitpod to feel that dev container magic. DevPod is a new open source tool that allows users to launch dev containers with any infrastructure that they have available.
DevPod uses a provider model like Terraform's, and there are currently providers for many different infrastructures, like local Docker daemons, Kubernetes, AWS, and several other cloud providers. It's also possible to develop providers if you don't find one that fits your needs.
While you can choose the infra you want to use with DevPod, you don't have to manage it. DevPod handles the lifecycle of the infrastructure it runs on, and it can even suspend cloud resources automatically to save on costs. DevPod uses the open devcontainer.json standard, so it's compatible with VS Code and many other IDEs, as well as tools like Codespaces.
We'll look at how DevPod works and get into a quick demo that showcases how it can help developers and teams standardize their dev environments.

Programming for accessibility
Programming for accessibilityRory Preddy My life is a hilarious roller coaster of miss-intended programming bugs because at 4 foot tall and 65 kilograms I completely fall off your radar.
What did my scale call me! Why does facial recognition see me as a child? These are all valid questions I often ask myself as I navigate my weird and different world. Have you heard the phrase “You have to be this tall for Micro-services”? well, what about: “You have to be this tall to operate a mobile phone?”. I am finding it harder and harder to reach any button except for “#” and “9”.
Building accessibility into the planning stages of programming can eliminate barriers for participation and create an inclusive environment for people with disabilities. Programming for diversity serves as an unquestionable indicator that your software embraces the diversity of your users and cares about their safety and comfort.
Join me on a fascinating and thought-provoking look at how you can program for accessibility.

BDD with Mockito
BDD with MockitoRory Preddy The BDD term was coined first by Dan North – back in 2006.
BDD encourages writing tests in a natural, human-readable language that focuses on the behavior of the application.
It defines a clearly structured way of writing tests following three sections (Arrange, Act, Assert):
-given some preconditions (Arrange)
-when an action occurs (Act)
-then verify the output (Assert)
The Mockito library is shipped with a BDDMockito class which introduces BDD-friendly APIs. This API allows us to take a more BDD friendly approach arranging our tests using given() and making assertions using then().

It demonstrates Kubernetes concepts like pods, deployments, services and how they relate. It also briefly mentions some advanced Kubernetes topics before opening for questions.
Dockercompose
DockercomposeRory Preddy Imagine proposing a session on “What’s new in Notepad”! Why would anyone want to know about such a common tool that everyone knows? The same should could be said about docker and docker-compose. They are standard development tools we find in any dev shop. So why does docker-compose seem so elusive? Its simple:
- Compose is a tool for defining and running multi-container Docker applications.
- With Compose, you use a YAML file to configure your application’s services.
- Then, with a single command, you create and start all the services from your configuration. Join me as we demo using Compose via your favourite frameworks.

Nashorn
NashornRory Preddy Rory Preddy's document summarizes the history and capabilities of JavaScript engines Rhino and Nashorn. It begins with the origins of JavaScript as a portable version of Java created by Netscape. It then discusses Rhino, an early JavaScript engine implemented in Java that compiles JavaScript to Java bytecodes slowly. Nashorn, introduced in Java 8, is 20x faster than Rhino as it compiles JavaScript directly to bytecodes without an intermediate compilation step. Nashorn also improves type handling and has a smaller memory footprint than Rhino. The document demonstrates key features of Rhino and Nashorn like script evaluation, function invocation, and lambda expressions.

Proactive Vulnerability Detection in Source Code Using Graph Neural Networks:...
Proactive Vulnerability Detection in Source Code Using Graph Neural Networks:...Ranjan Baisak As software complexity grows, traditional static analysis tools struggle to detect vulnerabilities with both precision and context—often triggering high false positive rates and developer fatigue. This article explores how Graph Neural Networks (GNNs), when applied to source code representations like Abstract Syntax Trees (ASTs), Control Flow Graphs (CFGs), and Data Flow Graphs (DFGs), can revolutionize vulnerability detection. We break down how GNNs model code semantics more effectively than flat token sequences, and how techniques like attention mechanisms, hybrid graph construction, and feedback loops significantly reduce false positives. With insights from real-world datasets and recent research, this guide shows how to build more reliable, proactive, and interpretable vulnerability detection systems using GNNs.

Who Watches the Watchmen (SciFiDevCon 2025)Allon Mureinik Tests, especially unit tests, are the developers’ superheroes. They allow us to mess around with our code and keep us safe.
We often trust them with the safety of our codebase, but how do we know that we should? How do we know that this trust is well-deserved?
Enter mutation testing – by intentionally injecting harmful mutations into our code and seeing if they are caught by the tests, we can evaluate the quality of the safety net they provide. By watching the watchmen, we can make sure our tests really protect us, and we aren’t just green-washing our IDEs to a false sense of security.

Exceptional Behaviors: How Frequently Are They Tested? (AST 2025)
Exceptional Behaviors: How Frequently Are They Tested? (AST 2025)Andre Hora Exceptions allow developers to handle error cases expected to occur infrequently. Ideally, good test suites should test both normal and exceptional behaviors to catch more bugs and avoid regressions. While current research analyzes exceptions that propagate to tests, it does not explore other exceptions that do not reach the tests. In this paper, we provide an empirical study to explore how frequently exceptional behaviors are tested in real-world systems. We consider both exceptions that propagate to tests and the ones that do not reach the tests. For this purpose, we run an instrumented version of test suites, monitor their execution, and collect information about the exceptions raised at runtime. We analyze the test suites of 25 Python systems, covering 5,372 executed methods, 17.9M calls, and 1.4M raised exceptions. We find that 21.4% of the executed methods do raise exceptions at runtime. In methods that raise exceptions, on the median, 1 in 10 calls exercise exceptional behaviors. Close to 80% of the methods that raise exceptions do so infrequently, but about 20% raise exceptions more frequently. Finally, we provide implications for researchers and practitioners. We suggest developing novel tools to support exercising exceptional behaviors and refactoring expensive try/except blocks. We also call attention to the fact that exception-raising behaviors are not necessarily “abnormal” or rare.

What Do Contribution Guidelines Say About Software Testing? (MSR 2025)
What Do Contribution Guidelines Say About Software Testing? (MSR 2025)Andre Hora Software testing plays a crucial role in the contribution process of open-source projects. For example, contributions introducing new features are expected to include tests, and contributions with tests are more likely to be accepted. Although most real-world projects require contributors to write tests, the specific testing practices communicated to contributors remain unclear. In this paper, we present an empirical study to understand better how software testing is approached in contribution guidelines. We analyze the guidelines of 200 Python and JavaScript open-source software projects. We find that 78% of the projects include some form of test documentation for contributors. Test documentation is located in multiple sources, including CONTRIBUTING files (58%), external documentation (24%), and README files (8%). Furthermore, test documentation commonly explains how to run tests (83.5%), but less often provides guidance on how to write tests (37%). It frequently covers unit tests (71%), but rarely addresses integration (20.5%) and end-to-end tests (15.5%). Other key testing aspects are also less frequently discussed: test coverage (25.5%) and mocking (9.5%). We conclude by discussing implications and future research.

TestMigrationsInPy: A Dataset of Test Migrations from Unittest to Pytest (MSR...Andre Hora Unittest and pytest are the most popular testing frameworks in Python. Overall, pytest provides some advantages, including simpler assertion, reuse of fixtures, and interoperability. Due to such benefits, multiple projects in the Python ecosystem have migrated from unittest to pytest. To facilitate the migration, pytest can also run unittest tests, thus, the migration can happen gradually over time. However, the migration can be timeconsuming and take a long time to conclude. In this context, projects would benefit from automated solutions to support the migration process. In this paper, we propose TestMigrationsInPy, a dataset of test migrations from unittest to pytest. TestMigrationsInPy contains 923 real-world migrations performed by developers. Future research proposing novel solutions to migrate frameworks in Python can rely on TestMigrationsInPy as a ground truth. Moreover, as TestMigrationsInPy includes information about the migration type (e.g., changes in assertions or fixtures), our dataset enables novel solutions to be verified effectively, for instance, from simpler assertion migrations to more complex fixture migrations.
