6:00-7:00 PM: Content Management Systems With Grails

Content Management means many things to many people, and the only thing more abundant than the number of content management systems out there today are the number of unique use cases for managing content. In this presentation, we'll discuss benefits and pitfalls of both common use and custom approaches, including how building a custom CMS in a rapid-development framework like Grails may be a much better solution for your organization than trying to use an off-the-shelf package. Concentrating on examples from my own journey from off-the-shelf to a fully-custom system, I will review some of the common use cases I've seen for content management in the enterprise, and how using frameworks like Grails enables developers and architects to build custom CMSs more simply, cheaply, quickly, and to a higher standard than products currently marketed as ready-made solutions.

7:00-7:30 PM: Pizza, Soda and Networking

Tek-Systems is sponsoring the pizza and the soda.

7:30-9:00 PM: The Pulse Project

This is a look at the SunSPOT platform (which has both open source hardware and software) and using Java in embedded systems. In this presentation we're going to look at implementing a Java powered pulse rate monitor. Along the way we will see how using Java and OOP make the implementation of digital signal processing algorithms clear by breaking them into small manageable pieces. We'll also touch on real-time concerns and using RESTful web services to provide the user interface for our system.

About John Lowe

Tuesday, October 13th Meeting

We will explore how to write Grails applications using Test First methods and how to debug and inspect Java applications using Open Source tools.

Rocky Mountain Software Symposium

The Rocky Mountain Software Symposium is coming back to Denver November 20 to the 22nd. We will raffle another pass at this meeting as well.

6:00-7:00: Test Driven Development with Grails

Not many of us question that TDD is the right way to write software, but not many of us really practice it either. Even fewer of us do it when writing a web app, and with good reason: web app code is usually coupled to a framework, and the framework is usually coupled to a web server on one end and a database on the other. All this coupling does not set us up for testing success.

Grails 1.1 introduces several features that make it easy and truly productive to create a web application while testing first. In this talk, you'll learn how to use Domain and Controller mocking to write unit tests that can be run quickly and easily from the IDE or from the command line. TDD with 100% coverage had always been possible in Grails, but for the first time the tools make it the kind of thing you'll want to do. Learn to use the new features of the framework to build your web app the right way the first time.

7:30-9:00: Java Open Source Debugging Tools

Expensive commercial utilities ruled the debugging market for years, but learn how a loose confederation of powerful Open Source debugging tools has adeptly fulfilled many of those same needs, and in many cases, taken debugging to the next level. In this bootcamp, get exposed to tcpdump, netstat, jps, jstatd, VisualVM, jhat and it’s OQL, Omniscient Debugger, TOD, Eclipse Memory Analyzer Tool, jtracert, btrace and more. Hear real-world scenarios of when to pull each out of your toolbelt, see each tool in action on a unified Java Web Application exhibiting a plethora of issues and leverage each tool to discover and solve the problem.
