Automatically enforce API Compatibility and OSGi Semantic Versioning during builds and code reviews

Writing good software isn't always easy; writing good and versatile open-source software that scales with time, with complexity, with amount and diversity of code authors, while increasing its development speed and keeping a huge ecosystem of extenders healthy for an extremely low to null maintenance cost on adopter's shoulders thanks to backward compatibility is even more challenging.
This is the challenge the Eclipse Platform has successfully faced for soon to be 2 decades, and has made it almost trivial to deal with in the last months.

Learning my Robot to Grasp with Promises and PushStreams

Tim Verbelen (imec)

Nowadays A.I. is the hype and everyone is talking on this awesome new neural network they trained. However, what is often overlooked is how to integrate such technology into a real system. In this talk I will show some results from our research lab on training a neural network to grasp objects. Instead of delving into the deep learning details however, I will focus on how we benefit from OSGi to integrate this onto a real robot system, and create some fancy API models using Promises and PushStreams.

It's time for the Resolution!

Tim Verbelen (imec)

Everyone deploying an OSGi bundle on a running system will have encountered a Resolution failed exception, due to some missing import packages. Although it may seem as a pain in the ass, the OSGi resolver can actually make your life a lot easier when used properly. In this talk we will go through the process of resolution, explain the requirement-capability model, and show how you can automatically assemble your application by using the resolver at build time. It's time for the re(s/v)olution!

Mastering Real-Time Sensor Data and Actuators with Realtime Java and Jamaica-IoT

Vladimir Nikolov (aicas GmbH)

The objective of this tutorial is to sensitize the audience for actual problems with real-time sensor data processing and actuator control arising at the edge of current IoT and Fog systems. These are mostly "open" systems allowing a dynamic arrival of applications and functions. Often, they must also meet certain performance and QoS criteria for the applications.

Time to add License Management to your Eclipse Product

Alexander Fedorov

Your Eclipse product is good enough to have license management, isn't it?

The Eclipse Passage project aims to provide rich and easily adaptable capabilities to define and control licensing constraints.

Promises in Java: Using Promises to Recover from Failure

BJ Hargrave (IBM)

Communications is error prone. Connections time out, servers fail to respond, returned data can be incomplete or corrupted. Bnd, the OSGi tooling project, has an HttpClient class which is used for communications including with remote repositories like Maven/Nexus and P2 repositories. The Bnd CI builds started having significant failures due to communications problems with the Eclipse download servers, so with some light code restructuring, I was able to add retry support to HttpClient using the Promises package from OSGi.

Building OSGi Projects with Bnd in Maven

Raymond Auge (Liferay Inc.)

Tim Ward (Paremus)

The OSGi Alliance via enroute.osgi.org and bndtools.org teams have spent a number of years focused on improving support for OSGi development in Maven. This talk will demonstrate the latest innovations demonstrating features such as quick setup, minimal configuration, use of bundle annotations, BOM support, integration testing, assembly and running, live coding, dual OSGi/JPMS library development.

OSGi CDI Integration Specification

Raymond Auge (Liferay Inc.)

The OSGi Alliance has developed a specification describing integration between OSGi and CDI. The combination of these two powerful development technologies opens the door to new possibilities. This talk will walk through the most essential features of the specification and show some code and running examples.

Event Driven IoT - Serverless Functions for OSGi

Tim Ward (Paremus)

In an ever increasing race to increase scalability, reduce configuration and decrease hosting costs “Serverless” computing promises to run your business logic “on demand” without the need for fixed infrastructure. As a dynamic, modular platform OSGi makes an ideal platform upon which to deploy your serverless functions. Furthermore, OSGi’s Requirements and Capabilities model allows for more complex serverless functions to be dynamically assembled and deployed in response to incoming events.

The Sling Feature Model - revealed!

Karl Pauls (Adobe)

David Bosschaert

In the search for a convenient, flexible and extensible OSGi deployment model for use by Apache Sling, the Apache Sling Feature model was created. Over the past 2 years this Feature Model has been taking shape in the community. The components developed include the model itself with a JSON serialisation, analysers that can check models for semantic consistency, and a Maven plugin that supports various tasks, such as producing minimal Docker images based on model definitions, and creating model aggregations.
