Nathan Reese on Complex Event Processing
Complex Event Processing with Esper - Turn your database upside down!
Warehousing data for mining is missing half of the solution. Learn how to mine data in real-time using Complex Event Processing. Featuring live CEP demos utilizing Esper, an open source java CEP library, this talk will literally turn your database upside down.

Andy Ennamorato on PubSubHubbub
PubSubHubbub: a simple, open, server-to-server web-hook-based pubsub (publish/subscribe) protocol as an extension to Atom and RSS. Gives publishers an assistant which notifies subscribers of updated content, so subscribers don't need to keep polling the publisher.

Eric Wendelin on The JavaScript Stacktrace Project
The JavaScript Stacktrace project was born out of the frustration of cross-browser debugging and aims to make supporting all browsers in your web application a little less painful. This talk will show you good JavaScript code structure for extensibility and testing, practical applications, and give you insights on how open-source software starts, grows, and thrives.
John Lowe on the JVM
With the growth of languages running on the Java platform the JVM has become a central element of our computing environments. Ironically, most developers don't actually know all that much about the JVM and how it executes code. In this session we are going to look at the JVM itself and answer some general questions: What is actually in a Class File? What do the byte code instructions actually do? What is done in class file Verification? How are multiple cores supported? How do the new generation of languages take advantage of, or hindered by the JVM? These and other questions will be covered in this summary of the JVM specification.

It's Clojure night!
Daniel Glauser on Intro to Clojure
LISP? Isn't that 20 years old? Indeed it is, but it was a language before its time. The hardware has finally caught up with the concepts of a LISP and we've got a wonderful implementation on the JVM that can co-exist with traditional Java code. Come find out what this Clojure revolution is all about and why the JVM is inciting this plethora of languages on the JVM.
Daniel Glauser on Web development with Clojure
You've heard about Clojure, the LISP language on the JVM, but have you heard about how it can be leveraged for web development? I bet not! Local clojure expert Daniel Glauser will share his real-world experiences on how LISP is making a comeback for thread safe, performant, and scalable web apps.
March 2nd, 2010 Meeting
Tim Berglund on Decision Making in Software Teams
Alistair Cockburn has described software development as a game in which we choose among three moves: invent, decide, and communicate. Most of our time at No Fluff is spent learning how to be better at inventing. Beyond that, we understand the importance of good communication, and take steps to improve in that capacity. Rarely, however, do we acknowledge the role of decision making in the life of software teams, what can cause it to go wrong, and how to improve it.
In this talk, we will explore decision making pathologies and their remedies in individual, team, and organizational dimensions. We'll consider how our own cognitive limitations can lead us to make bad decisions as individuals, and what we might do to compensate for those personal weaknesses. We'll learn how a team can fall into decision-making dysfunction, and what techniques a leader might employ to return healthy functioning to an afflicted group. We'll also look at how organizational structure and culture can discourage quality decision making, and what leaders can do to swim against the tide.
Software teams spend a great deal of time making decisions that place enormous amounts of capital on the line. Team members and leaders owe it to themselves to learn how to make them well.
Randy Kahle on NetKernel
NetKernel is a software platform that runs on the JVM. It is based on a very small pure REST kernel and includes tools and services in its stack (much like Unix). Like the Web, everything in NetKernel is identified by a URI.
NetKernel started as a research project in HP Labs in 1999. Since 2002, the technology has been advanced by 1060 Research. We are releasing NetKernel 4 on 10/9/2009 and this represents a major step forward in the refinement of the abstraction and platform.
NetKernel is used by large corporations (e.g. BlueShield of California) governments (e.g. US Army, Intelligence Agencies) and small companies. All report the same - applications built on NetKernel run faster, require less code, scale with cores and in general, simplify systems.
Bio:
Randy has worked at GTE Sylvania, HP, Microsoft, MageLang Institute, lead his own consulting company and is currently working with 1060 Research. He has worked with Java from the very beginnings of the language and was an early consultant, instructor and architectural advisor to investments banks, manufacturers and service companies. Randy is currently working on NetKernel.
