This was my second day:
Michael Tamm (optivo GmbH): Feature Toggles on Steroids
Very good summary off all topic’s covering feature toggles. Wish I had this summary 2 years before, were we have evaluated this. Unfortunately furthermore no solutions for declarative frameworks like Oracle ADF with it’s wizards and xml configurations, which later generated code. Ironic answer to my question: “Don’t use frameworks – use Java”
Alexander Casall (Saxonia Systems AG): User Experience for techies
Now comes someting completely different. As least I had expected. No techniques etc.. There are really german standards “Ergonomics of human-system interaction” in ISO 9241 – 110 (Dialogue principles) and ISO 9241 – 210 (Ergonomics of human-system interaction). I have to read this, if it really would help in development, or the presenter interprets this on its own. Nice and surprising presentation.
Adam Gowdiak (Security Explorations): Java (in)security (Keynote)
The presenter is really angry about Oracle and co. and the security in Java. Nevertheless it seems he has specialized only on this topic and earn this money on this. So I doesn’t know, if somebody or another product is better. What about security in OpenJDK? And what are now my alternatives? A little depressing keynote.
Lars Röwekamp (open knowledge GmbH): Courage to professionalism
I don’t know, what I had expected here, but this was a nice surprise too. The talk was about to find a common language between customer, analyst, developer and other roles. The patterns “Rich Entities” and “Value Objects” helps to find a way out of the helper, util and manager class hell and seems to improve the readability of the code for all stakeholders. But how will this fit in declarative Frameworks like Oracle ADF and it’s generated classes? Have to think about it. Very good speaker!
Unfortunately the worst presentation comes from Oracle itself. To be fair: this presentation should be held by Bruno Borges, which was prevented to come to Javaland. Tip: Never hold a presentation, which is created by another person, if you don’t know, what he know about the subject. But I’m not sure if I had understood more, if Bruno had held the presentation. I didn’t find a red thread in the slides. And I must add, I didn’t really find an alternative presentation in this time slot.
Alexander Heusingfeld, Tammo van Lessen (innoQ Deutschland GmbH): When Microservices Meet Real-World Projects: Lessons Learned
Interesting presentation but the topic was missed. This had little to do with Microservice, more what a consultant or any person has to learn on his way from Junior to Senior: communicate, communicate, communicate. Especially when you want to change something.
Stephan Kaps (Bundesversicherungsamt): Flyway vs. LiquiBase – Battle of the database migration tools
I wanted to do this comparison several times before, but had never enough time. Now I’m relative sure that I will start with Liquibase in my next private project before I develop the application. This was the subjective winner of the battle too. I’m overwhelmed by the mass of features of both tools. Very good summary!
This was a nice workshop to plan the application and technical architecture of a given small set of requirements. Result for me: the many participants from a lot of other companies comes to very similar architecture depending on the assumption they made. In real life you have to communicate again and again with your stakeholders to get answered all of the questions and get quick feedback from them. I have urgently to refresh my knowledge of tools for UML diagramming and graphical presentations. And for structured proceeding maybe I should look for TOGAF training?
This was inspiring conference, which gives me a lot of fresh ideas and reminders for some spilled goals for my private and company projects. I think we’ll see us next year!
