Presentation #1: Easing into Agile
“How do you get started with an Agile development methodology? Everyone
has been talking about eXtreme Programming for years, but how do you get
it introduced to your team? Many times, you’re not simply transitioning
from from one methodology to another — you’re introducing a methodology
for the first time. Adding structure to a previously unstructured
endeavor. Adding a touch of discipline where programmers once roamed free.”

Presentation #2: Real World Grails
“Scott Davis is the Editor in Chief of aboutGroovy.com. The website, in
addition to being, umm, about Groovy, is implemented in Grails. This
talk shows you how to get started with Grails, but also talks about the
experience of using it in a live, production web site.

Grails is a web framework that maximizes the strengths of familiar Java
libraries — Spring, Hibernate, and Sitemesh, to name a few — while
minimizing the XML jockeying it usually takes to get them all to play
nicely with one another. It brings “Convention over Configuration” to
Java. It uses Groovy as the language to glue the pieces together, which
means that experienced JEE developers can learn Groovy in the context of
libraries that they are already familiar with.

Grails includes a web server, a database, and all of the libraries
necessary for a full-fledged web application. It will even generate a
directory structure and scaffold common classes (Controllers, Views,
etc.). It is no exaggeration to say that you will have your first
application up and running in minutes. But Grails is more than about a
quick start. In this talk, we’ll look at ways to move beyond the default
configurations. We’ll deploy a Grails app to an external Tomcat instance
instead of the included Jetty server. We’ll move from the default HSQLDB
database to MySQL. We’ll include external JARs to bring new
functionality to the mix.”

In case you are interested, there is a new API, that supports a standard interface to any compliant scripting engine, within the javax.script package in Java 6. John Hunt over at Reg Developer has a great educational article on this API and how you can use it:

In an ideal world, rather than invent our own scripting engine we could have used an existing engine, one that supported a well-known or standardised language. Such engines are now available and indeed implementations for Java can be obtained both commercially and as open source projects. However, such engines each tend to have their own interface and standards.

Java Standard Edition 6.0 introduces a new API that supports a standard interface to any compliant scripting engine. This feature allows different scripting engines to be plugged in, but all are accessed in the same way, through a standard API.

Read complete, ready-to-print article here.

Due to the closeness to the holidays, we are going to move the meetings to the second Tuesday of the month for both November and December.

So, our meetings will be:

• November 14th
• December 12th

Meeting times will stay the same:
5:30 food/social time
~6:00 speakers
Looking forward to seeing you at the Gallup.com meeting location!
Location:
Gallup Riverfront Campus
1001 Gallup Dr, Omaha, NE

Hope to see you there!

This month we are changing things up a little more with nothing but lightning talks.  Each talk will be about 15 - 20 minutes, with a little time at the end for questions.  We do not intend to do this for every meeting, but this does give people a chance to get up in front of a (mostly) harmless group and talk about something they are interested in.

• An Introduction to Closures - Blaine Buxton
• Driving Selenium with Groovy - Kyle Dyer
• Code Coverage tools - Scott Hickey
• Using CruiseControl - Matt Secoske

We are also introducing a new peice to the meetings: Open Discussion - people can talk about problems they’re facing, things that are interesting to them, etc.  Bring your toughest problem right now with you and see if we can’t solve it together!  If you have code snippets that can elaborate the issue, by all means bring them too!

October 17th - Food and Soda starting at 5:30PM , presentation to start around 6:00PM

Location:
Gallup Riverfront Campus
1001 Gallup Dr, Omaha, NE
(402) 951-2003

Hope to see you there!
