Presentation: Tips and Tricks for writing low latency Java applications

This is presentation that offers tips in tricks, and generally things you need to know to be effective in writing low latency Java applications. You’ll also have an opportunity to learn a few things about a modern JVM’s garbage collector and JIT compiler, but more importantly what aspects of those impact your ability to write low latency applications.

Bio: Charlie Hunt is the JVM Performance Lead Engineer at Oracle and the lead author of the Java Performance book, (published October 2011). At Oracle, Charlie is responsible for improving the performance of the HotSpot Java Virtual Machine and Java SE class libraries. He has also been involved in improving the performance of both GlassFish and WebLogic application servers. He wrote his first Java application in 1998 and joined Sun Microsystems, Inc. in 1999 as a Senior Java Architect. He has been working on improving the performance of Java and Java applications ever since. He is a regular speaker on the subject of Java performance at many world-wide conferences including the JavaOne Conference. Charlie holds a Master of Science in Computer Science from the Illinois Institute of Technology and a Bachelor of Science in Computer Science from Iowa State University.

Btw, if anyone happens to have purchased the Java Performance book and brings it along to the meeting, Mr Hunt is happy to sign it.

You can find his book at Amazon.

In this talk, we will look at strategies to adopt the best security for your Java applications. The talk will describe the best choices for authentication and authorization for your applications. The talk will finally talk about the Identity Management standards – SAML,WS-Trust, OpenID and OAuth and how they can be adopted using PicketLink. Facebook and Twitter based authentication mechanisms are also discussed.

Gradle: Bringing Engineering Back to Builds

By No Fluff Just Stuff speaker Tim Berglund

Gradle. Another build tool? Come on! But before you say that, take a look at the one you are already using.

Whether your current tool is Make, Rake, Ant, or Maven, Gradle has a lot to offer. It leverages a strong object model like Maven, but a mutable, not predetermined one. Gradle relies on a directed acyclic graph (DAG) lifecycle like Maven, but one that can be customized. Gradle offers imperative build scripting when you need it (like Ant), but declarative build approaches by default (like Maven). In short, Gradle believes that conventions are great — as long as they are headed in the same direction you need to go. When you need to customize something in your build, your build tool should facilitate that with a smile, not a slap in the face. And customizations should be in a low-ceremony language like Groovy. Is all this too much to ask?

Gradle has received the attention of major open source efforts and has chalked up significant conversions by the Spring Integration, Hibernate, and Grails projects. What do these technology leaders see in this bold new build tool? They see not only a better way to build Java applications, but an extensive ecosystem of connecting to existing Ant and Maven build files while expanding the horizon of test, CI, and deployment automation in an easy manner. Let us take you on this same walk of discovery of the most innovative build tool you’ve ever seen’.

The Speaker:

Tim Berglund is a full-stack generalist and passionate teacher who loves coding, presenting, and working with people. He has recently been exploring non-relational data stores, continuous deployment, and how software architecture should resemble an ant colony. His firm, the August Technology Group, helps clients with product development, technology consulting, and technology upgrade projects atop the JVM.

Tim is a speaker internationally and on the No Fluff Just Stuff tour in the United States, and is co-president of the Denver Open Source User Group in the Denver area, co-author of the DZone Clojure RefCard, co-presenter of the best-selling O’Reilly Git Master Class, and co-author of a forthcoming series of ebooks on the next-generation build system, Gradle.

We will also give away a ticket to the Great Lakes Software Symposium, the No Fluff Just Stuff conference that will happen in Chicago November 11-13.

ActiveWeb Presentation

It was a great presentation and looks like a good framework. Check it out.

Chicago developer Igor Polevoy will speak on the ActiveWeb framework.

ActiveWeb is a full stack Java web framework. It includes all aspects of web development and especially promotes BDD/TDD. It allows to describe application behavior in tests before implementation. It also helps take developer productivity to a new level by refreshing new code in the application on the fly, eliminating compile/build/deploy cycle. In this session, learn to how to be more productive with ActiveJDBC and ActiveWeb.

Igor Polevoy has years of experience of building enterprise applications as a developer, an architect and a manager. He has been teaching various Java and Ruby related topics at the DePaul University for over 10 years. Igor is an author of open source projects ActiveJDBC and ActiveWeb.

The speaker is Jeff Schwartz. He is the founder and Director of Mobile and Cloud Technologies at Chicago consulting firm NoNa, Inc, and co-chair of Mobile Mondays Chicago. He has over 15 years experience as a software developer.

The topic is the Play Framework: http://www.playframework.org/
It is a Java web framework that uses REST and convention over configuration. It is a stateless, asynchronous, full-stack, pure Java framework that aims to help web developers have more fun and be more productive.
