Using Git with Subversion

Thu, June 17

Presented by Carlus Henry

After watching Linus Torvalds Google Talk about Git, I was eager to start using it immediately due to all of the productivity gains. Unfortunately, I work in an environment that uses Subversion and using Git was out of the question....until I learned about git-svn.

During this presentation, I will show you how to use Git with Subversion. I will also share with you real life experiences that Git has allowed me to do things that would have been impossible with Subversion or at least extremely difficult and time consuming. If you are working in a Subversion environment and you want the productivity gains that comes with the use of Distributed Version Control Systems (DVCS), then this is the talk for you.

Scala

Thu, Feb 18

Presented by Carlus Henry

Scala is a programming language for the JVM that is gaining popularity. This statically typed, type inferenced language is difficult to classify because it is a scripting, object oriented, functional programming language all in wrapped into one. Come to the February meeting where Carlus Henry will be presenting on the Scala programming language and why he has decided that it will be the language that he will be focused on learning this year.

Driving Behaviour with Cucumber on the JVM

Thu, Jan 21, 2010

Presented by Zach Dennis

This talk introduces Cucumber, which can be used to drive development from the features requested by the stakeholders down to the underlying implementation - working outside-in. This style of development comes from Behavior Driven Development and while Cucumber came to life as a ruby tool it as evolved in a language-agnostic BDD toolset, operating on the JVM, the .NET platform, Ruby, Python, and Flex.

Google Web Toolkit (GWT)

Thu, Nov 19

Presented by Andrew Miller

With so many great JavaScript toolkits available on the web, what makes the Google Web Toolkit different? Instead of writing JavaScript yourself, you write Java and it compiles your class files into highly optimized JavaScript. I'm going to give an overview of GWT and provide some techniques for building large web applications using GWT.
