GeeCon Conference Day II (Friday 13th May)

So my review of the second presenattions:

1. Jim Webber "Revisiting SOA for the 21st Century"

Jim is an excellent presenter. I have no chance the take a nap on his morning presentation. A lot's of jokes, quite offensive, controversial, but funny. It makes you think about what you are actually doing and why for your projects. Liked that a lot.

2. Emmanuel Bernard "Hibernate Validator / Bean Validation Best practices"

Emmanuel is one of the Hibernate developers from the very beginning. Quite an interesting presentation about new features with Hibernate Bean Validation. A lot of good code examples. Hope to find some of that somewhere. Also a lot of non-trivial use cases for the Hibernate Validation usage.

3. Eugene Ciurana "The No-Nonsense Guide to Hadoop and HBase in Enterprise Apps"

That's the first presentation  about Hadoop and HBase that I've heard. Once again a little explanation of modern Non-RDBMS's. Eugene showed how this stuff works and what is practical benefit of adopting this stack. Good presenter, lot's of fun. Slides arehere. Oh, almost forgot. There was a cool CAP triangle with all modern Databases listed on its edges. A very descriptive.

4. Marek Matczak "10 common pitfalls when using Hibernate"

Marek works for the Capgemini and has a lot of experience with Hibernate. Some useful (non-trivial) practical advices described in the presentation. Waiting for the slides to be available.

5. Emmanuel Bernard "Hibernate OGM: JPA on Infinispan: when PaaS persistence meets Java EE"

Very interesting presentation about Hibernate OGM. Hibernate OGM main goal is to have the JPA interface to the Non-RDBMS. OGM team started with Infinispan and Hibernate search and reused a lot of existing code in it's project. I liked presentation very much despite the fact that OGM practical usage is still very unclean.

6. Eugene Ciurana "3 Case Studies in NoSQL and Java in the Real World"

This presenatation was about three stacks with short explanation. MongoDB, GigaSpaces XAP, and of course Hadoop/HBase. Than there were three case studies. A good overview once again. Slides are here.

7. Jim Webber "A programmatic introduction to Neo4j"

Once again Jim rocks. A good short introduction to the Non-RDBMS (I could not even count how much of them I heard during the conference) and after that all about Neo4j. Which is a graph database. As we all know the graph is perfect for some types of tasks but have some gaps. Looking forward to have a video to show to my colleagues.  BTW examples are on the GitHub.
