GeeCON 2016 is taking place in Krakow this coming week and I’ll be speaking about data processing with Infinispan’s distributed streams on Thursday, 12th of May. So, if you are interested in how to analyse your data using standard Java Streams API in a distributed environment, make sure you come to my talk! :)

DevConf.cz (Developer Conference) is a free annual conference for all Linux and JBoss Community Developers, Admins and Linux users organized by Red Hat Czech Republic in cooperation with the Fedora and JBoss communities. See more details on DevConf’s homepage.
Since it’s JBoss related conference, Infinispan cannot be missing there! We had two Infinispan related presentantions. First of them was presented by Jiří Holuša focusing on new features in Infinispan 8. The presentation also covers very gentle introduction to Infinispan in general.
The second one, named "From Big Data towards Fast Data", was given by Vojtěch Juránek and talked about latest trends in Big Data world. The presentation goes through the introduction about Big Data, mentions the problems with it and comes up with the term Fast Data. Some approaches are presented, how to solve this Fast Data phenomenon, ending up with new Infinispan Spark connector as one of the possible solutions.
Please, see the links below.

Last week the first ever Snowcamp was held in Grenoble where I presented about "Distributed Data Processing with Infinispan and Java Streams".
The talk went well and fortunately the demo gods were with me that day :). The code of the demo can be found in this Github repository. The slides will be available soon.
Of the presentations I attended, I was particularly impressed with the Apache Zeppelin talk that Saad Ansari presented where he demonstrated how to do interactive data analysis on top of Apache Spark, very cool!
It was a pleasure being selected to talk at Snowcamp and hope that next year I can speak there too!

The first ever JUDCon Brazil was held a couple of weeks back and it was a real blast! Firstly, it offered a great opportunity to meet some members of the JBoss community which have been helping us push JBoss projects forward in this region of the world, such as Hanneli Tavante, Roberto dos Santos Wagner, …etc. It was great sharing ideas, experiences…etc with them and coming up with new ideas!
As mentioned before in the post before the conference, I had two new presentations to deliver, one on JSR-107 specification on JCache API and Infinispan’s implementation, and the other on Hibernate Second Level Cache with Infinispan. The JCache presentation went really well and all the live coding worked as expected.
The second presentation was the busier of the two, with a full room packed with Hibernate/JPA users waiting to hear how to scale up their applications. I got excellent feedback from both presentations and looking forward to giving these presentations in more user groups or conferences.
The presentations are not up yet, but I expect them to be posted online in the next few weeks. In the mean time, here are a couple of temporary links to the PDFs of my presentations:
The big news of the conference was for sure the announcement of JBoss Application Servers' new name: WildFly. We’re actively working with them to make the most out of Infinispan :)

I will be talking about datagrid performance and capacity planning and Radargun at this year’s edition of Berlin Buzzwords, 4-5 June (I’ll let you guess the location). My very first time at this conference but the amount of positive feedback I received about it was huge, so really looking forward to it!

As a seasoned public speaker, I don’t easily get flustered by minor glitches that inevitably occur when presenting or doing live code demos. I expected a recent JUG and JBUG tour of the American mid-west to be no different. I was prepared to speak about JSR 107 and JSR 347, Infinispan, and a wee bit on Hibernate OGM and NoSQL. All subjects I’m pretty familiar with, totalling to about an hour of yacking. Followed by a live coding demo to walk people through Infinispan’s core API. Simple.
So where does one start when talking about what went embarrassingly wrong at the Madison Java User Group on the 29th of Feb? Well, I suppose mistaking my iPad VGA connector for the mini displayport to VGA connector for my MacBook when leaving London was a start. Mix in the fact that this realisation only happened in a room full of people, with a few minutes to go before the start of the talk. Nice. Unable to connect my laptop to the projector, I had no choice but to present off my iPad instead. Which was fine, except that ten minutes into my talk, my iPad spuriously decided to shut down. Epic fail. But who needs slides, right? Not me, for sure - I’m way too cool for that. So I continued on, unfazed. Now try explaining Eric Brewer's CAP theorem without any visual aids. Fun, right? I tried to use the whiteboard. No pens! The organiser rushed out to find some. And none of them worked! Even old-school technology was failing on me that day.
Then come demo time, I was able to borrow a Linux laptop from Red Hatter Jey Paulraj who was in the audience, and transfer my demo to it. Given that the laptop didn’t have the tools needed to actually run the demo, the entire demo consisted of me just walking people through an Infinispan configuration XML file. For half an hour. Suspenseful and thrilling! Well, peppered with anecdotes about the life of an open source developer and several tangents on the architecture of various parts of Infinispan, the time did actually fly by (and the audience did seem at least somewhat engaged!)
The clincher, though - I had a PDF containing URLs where people could download the demo, and learn more about the JSRs and Infinispan. Bringing this PDF up on Jey’s laptop, still projecting for the benefit of the room, resulted in his PDF viewer crashing. That’s when I threw in the towel - any more information from me would require tequila, preferably delivered intravenously!
Now for the moral of the story, don’t trust technology. Always be prepared to get your message across with no visual aids whatsoever. Oh, and don’t forget your Macbook’s VGA adapter. :)
Addendum 2: I now am on a short break climbing in the Canadian Rockies, but will soon be presenting the same in Washington DC - drop by if you’re in the neighbourhood!
