The Adventurous Developer's guide to JVM Languages

Today there are over 50 actively worked JVM languages in existence today. Some have been ported to the JVM while others have been written specifically for the JVM. This hands on session with take an introductory (but non hello, world) look at a number of JVM languages including, Java 8, Scala, Groovy, Kotlin, Ceylon, Xtend and Clojure as well as the tooling support.

JRebel in the Enterprise

Rebel rose as a research project to solve the problem with redeploying the Java applications that led to enormous turnaround cycles. The longer is the turnaround time, the more room for distractions there is, leading to long unintentional breaks and loss of the focus. Read More

Scalable language, scalable DB - accessing OrientDB with Scala

NoSQL is here to stay - for better or worse. There are document, graph, column, key-value databases - all serve specific purposes well. Today I want you to look at relatively new and unknown player - OrientDB. Why is it different and why should you care? Read More

OutOfMemoryErrors Explained

Using the JVM source code, Kees Jan compiled a list of all out of memory errors that you may run into when running Java systems. Using code samples, tools and experience Kees Jan explains what each of these errors mean, how they come about and what to do when you see one. Read More

Introducing HIP, the Human Interaction Protocol

Humans have wonderfully weird interfaces. Ranging from elegantly simple to brutish and infuriating. It is an interface that we all use every day. It is so prevalent that, regrettably, we tend to forget it is there. For all their love of tinkering with systems, developers seem to have no interest whatsoever in hacking this API.

HIP is Open Source, with nearly 7 billion users and almost as many contributors. Over the course of history, the API to humans has been well documented and explored. It is the only API that can be talked about at parties.
