Here are my notes for one that caught my eye, Using Spark, Kafka, Cassandra and Akka on Mesos for Real-Time Personalization. This is a very dense but well delivered presentation by Patrick Di Loreto who helped develop a...

GeekOut 2015 Summary
I last had the pleasure of visiting the lovely Baltic city of Tallinn in 2012, when I presented JSF 2.2 and the Rockstar talk at GeekOut 2012. Now that I've got something new (for me anyway) to talk about I made the cut and was invited back to present Servlet 4.0 at GeekOut 2015. Attendence was capped at 400, giving this conference a very exclusive feel. Indeed, 99% of...

ConFESS 2015 Wrap Up
Hard on the heels of JavaLand was ConFESS. This was the eighth installment of the conference that started life in 2008 as JSF Days, switching to the name "ConFESS" in 2011. The name stands for the "Conference for Enterprise Software Solutions". Last year, ConFESS was held as a partnership with JavaLand in Brühl Germany. Neither party was satisfied with how that...

JavaLand 2015 Wrap Up
After months of preparation, it all came down to three days of intense execution, and I was just one speaker. I can only marvel at the logistical acumen that was on display from the JavaLand and DOAG team. I had an action packed agenda: two conference sessions, two Early Adopter's Area (EAA) session, and one training day session. Thrown into the mix were a couple 1:1...

JavaLand 2015 Early Adopter's Area
With only 25 business days to go until JavaLand 2015, now's a good time to share the plans for the Early Adopter's area and Hackergarten. As at many other Java community conferences, this is a space where anyone can visit and meet with leaders of different parts of the Java ecosystem to see first hand what's new in their own little patch of the Java world. The...

With only 44 business days to go until JavaLand 2015, I’d like to share my conference picks. I’m including my sessions for completeness, and naturally I recommend you attend them, but I’ll also include an alternate that I’d attend if I wasn’t speaking at that time.

With all of my formal JavaOne conference obligations satisfied, day four was dedicated to listening. Another day, another hotel. The community keynote had a little bit of everything and was in the San Francisco Marriott, bringing to four the total number of separate buildings I had to visit for JavaOne. The complete keynote is available at Oracle. The room was full, and Intel VP Michael...

Automating Deployment of the Summit ADF Sample Application to the Oracle Java Cloud Service
on Jun 4, 2015
In an earlier post I wrote about Getting to Know the Developer Cloud Service. There wasn't an IDE used in that post and I'm a big fan of IDEs. So in this post we'll look at how Eclipse, in combination with the Oracle Developer Cloud Service, can be used to support the complete application lifecycle, from inception to production. In between we'll create bugs, create code branches, initiate code...

Bunyan is a NodeJS library that rethinks logging in some really useful ways. I wrote a Java port you can use in your applications.
In particular, with Bunyan, logs are JSON - and Bunyan comes with a great filtering and analysis tool.
The Java port uses some innovative techniques to make logging simple and foolproof - in particular, a use of AutoCloseable to make a logging code simple and...

Validating Oracle Java Cloud Service HA
One of my favorite applications from my Sun Java System Application Server days was the Cluster JSP Sample Application. In a cluster configuration fronted by a load balancer, this simple JSP provides a nice summary of which cluster node handled the request as well as the ability to test session failover. Therefore, why not try it on the Oracle Java Cloud...

One of the most popular information visualization charts in D3 is also one of the most maligned: the word cloud. Also known as a tag cloud, the word cloud uses text and text size to represent the importance or frequency of words. Figure 1 shows a thumbnail gallery of 15 word clouds derived from text in a species biodiversity database. Oftentimes, word clouds...
