BASIC CONCEPTS: Tail Call Optimization and Memorization Techniques in Modern JVM Languages

Recursion is a highly expressive technique that’s common in divide and conquer strategy and also in dynamic programming.  Modern JVM languages like Clojure, Scala, and Groovy offer techniques to optimize recursion and also to facilitate dynamic programming. In this presentation we’ll take a look at the nature of the problems that can use these techniques, and dive into code examples to use these techniques.

MAIN PRESENTATION: Concurrency without Pain in Pure Java

Programming concurrency has turned into a herculean task. I call the traditional approach as the synchronized and suffer model. Fortunately, there are other approaches to concurrency and you can reach out to those directly from your Java code. In this presentation we will discuss the actor based concurrency and also the software transaction memory. We will then develop examples using AKKA and compare the power of these approaches in contrast to the traditional approach.

Look for the building with the UNC signage on it as Bldg 758 might be difficult to see.
