• Speaker training in partnership with Devoxx and IBM

    IBM Client Center Brussels

    Want to become an international rock star speaker?

    We're running a speaker clinic/training for those of you keen to submit a talk to a conference, but looking for guidance on where to get started.

    We will cover the basics, giving you some simple guidelines to help prepare you for your first presentation, as well as some insider tips to consider when submitting your talk ideas.

    The most important thing you should get from this session is probably how you’re going to handle having a sea of faces staring expectantly at you when you take to the stage.

    This session is aimed at both audience and NOVICE speakers - people who have never done it before, or have limited experience with presenting, and want to take that first step.

    Come to this session if:

    • You'd like to present at a local User Group event, but you're not confident enough yet
    • You're wondering if you could present at Devoxx or another conference
    • You want practical help getting started with public speaking
    • You're simply curious about what it's like

    This is very much an introductory session (although more confident speakers are welcome), and will focus on your skills as a presenter, not the mechanics of building a slide deck or talk.

    Beyond the event we'll help to connect you with a mentor who can guide you all the way through to your first lightning talk/evening presentation to your first conference presentation.

  • RESTful API-design, Miredot and Java on Mobile

    The Persgroep

    Hello everyone, we’re happy to announce our first BeJUG 2016 event on April 19th. Yves Vandewoude and Bert Vanhooff will talk about Miredot, RESTful API-design and documenting these APIs. Followed by a session from Johan Vos about Java on mobile.

    We would like to thank the Persgroep for hosting our first BeJUG event of 2016.

    Planning: 18h00 reception, 19h00 start of our first session
    Location: The Persgroep, Brusselsesteenweg 347, 1730 Asse (Kobbegem)

    As always, please update RSVP when unable to attend to allow other people to join because places are limited.

    Miredot, RESTful API-design and documenting these APIs

    The world is interconnected by APIs more than ever. It is almost unimaginable to develop any kind of software today that doesn't either offer or invoke a web-API. The majority of (new) APIs offer a REST + JSON interface. The Java platform is very well equipped to develop such APIs. In our talk we'll quickly recap what REST exactly means and what good RESTful API-design looks like. We'll continue by showing a few code examples using Jax-rs and Spring-mvc, combined with frameworks such as Jackson (for Json parsing). Since we are creating an open API that any customer should be able to use from any programming language, technology-neutral documentation of this API is key. We can't stress this enough. We will present an overview of different possibilities of documenting APIs, ranging from the API-first approach (RAML, Apiary, etc.) to generators (Swagger, Enunciate, etc.), including Miredot.

    Yves Vandewoude has a Master in Engineering (Computer Science) degree and obtained his PhD on dynamic sofware evolution from the faculty of engineering in 2007. After a brief stay at the university as a Post-doctoral researcher (mainly involved in industrial software-architecture related projects), he co-founded Qmino and has been a Java consultant and team lead during the last 8 years. He is obsessed by code and - maybe even more - documentation quality.

    Bert Vanhooff is a Master in Computer Science, he obtained his PhD on software modelling and transformation from the university of Leuven in 2010. During his research, he worked on several industrial projects and stayed at INRIA in Nantes (France). He co-founded Qmino and has been a Java consultant for 8 years. He is passionate about all things visual/UX and likes clean code design.

    Both have extensive expertise in the Java ecosystem and are regular attendends of Devoxx and JavaOne.

    Qmino is a small software development firm whose activities have varied from the development of large scale software systems (with a specific focus for GIS related software systems) to software for mobile phones and tablets. Through the years, Qmino has built significant experience and expertise in the design of multi-tier systems including (RESTful) API design and development. Qmino, always set out to be a product company, started developing Miredot a few years ago. Miredot is an automatic documentation generator for Java-based webservices.

    Java on mobile

    For many years, Java on mobile devices suffered from fragmentation and distribution issues. Today, with the increasing interest into native app development, Java is getting very strong on mobile devices. In this session, we will show a number of ways to run Java applications on iOS and Android devices. We will show how easy it is to create an application using your favourite IDE, and have that application running on an Android and an iOS device without changing a single line of code.

    Johan Vos started to work with Java in 1995. He was part of the Blackdown team, porting Java to Linux. His main focus is on end-to-end Java, combining back-end systems and mobile/embedded devices. He received a Duke Choice award in 2014 for his work on javafx on mobile. In 2015, he co-founded Gluon, a company working on Java for the (mobile) client, which received a Duke Choice award in 2015. Johan is a Java Champion, a member of the BeJUG steering group, the Devoxx steering group and he is a JCP member. He is the lead author of the Pro JavaFX 8 book, and he has been a speaker at numerous conferences on Java.

  • Microservices with Stijn Van den Enden & Andreas Evers

    Business Faculty Brussel

    Hey everyone,

    On Tuesday, the 20th of October we'll organize another BeJUG event around the topic Microservices. We would like to thank Tobania for hosting this event.

    Microservices are a true hype these days. Netflix, Amazon, eBay, … are all using microservices, but why? The idea is simple; split your application into multiple services which can evolve autonomously through time. The name suggests to keep these services small. Conceptually this seems not all that different from a classical Service Oriented Architecture (SOA). Nonetheless, microservices do offer a new perspective. A monolithic application is divided into a couple small services which can be independently developed, deployed and scaled. Flexibility is increased, but using this model also has some pitfalls.This session sheds a light on the microservices landscape; the key drivers for using the pattern, tooling to support development and maintenance, and the pros and cons that go with it. We’ll also introduce some key design principles that can be used in creating and modelling these modular enterprise applications.

    This time we'll meet in Business Faculty Brussel where Tobania welcomes us at 6pm. Presentations will start around 7pm.

    Hope to see you all soon!

  • Java EE 8 where are we? by David Delabassee

    Java EE 8 where are we? by David Delabassee

    Java EE 7 has been finalised mid 2013 and from J2EE to Java EE 7, much has changed ... but we are not done yet! Through the years, Java EE has always reinventing itself. Java EE 8 will be no exception to this rule!

    In this session, we will look at the current state of Java EE 8. We will review the various new JSRs that will be part of Java EE 8 (e.g. MVC, JSON-B, Security JSR). We will obviously also look how the existing technologies will evolves in Java EE 8 (e.g. Servlet 4 which brings HTTP/2 support, JMS's plan to replace Message Driven Beans, CDI/EJB alignment, JAX-RS 2.1, etc.).

    We will finally conclude this discussion by looking at how you can get involved in those works.

    David is a Software Evangelist working for Oracle; his primary focus is Java on the Server-Side, i.e. Java Enterprise Edition. Prior to Oracle, David spent a decade at Sun Microsystems focusing on Java end-to-end (from the smart card to the high end server), related technologies and developer tools. In his various roles, David has been involved in numerous Java projects since the early days of this technology.

    David lives in Belgium. In his spare time, he enjoys playing video games with his daughter and tinkering with technologies such as Java, Home Automation, Electronics and Pinballs. You can find him on Twitter using @delabassee
