Come on out this month to Datran Media at 7th and Brazos (just inside the doors, there is a bank of elevators; head to the 8th floor) to catch a tutorial on state machines and pick up some new Ruby ORM skills. As we tend to do, we will be meeting on the fourth Tuesday of the month to discuss Ruby and Rails for a couple of hours. Afterwards we will adjourn to the local pub to continue the conversations. Make sure you arrive a bit early to get a good spot!

Crossing State Lines on Rails

Donald Wilde got into programming from a desire to control his trains as a kid. He never has gotten around to doing that (though he's helped his Dad do so), but he's programmed just about everything else from wire handling machinery to voice-operated VCR controllers. Since 1997, he's been involved with web programming and FOSS as a contributor and a consumer.

State Machines have been a cornerstone of systems design for a lot longer than transistors and the Gang of Four. After a rapid tour of the basics to get you thinking, we'll get into the meat of the presentation: an examination of two different Ruby implementations with practical demonstrations in a Rails environment. Don will leave you inspired to consciously add state machine design to your Controller toolbox and point you to starting points for learning more.

DataMapper: Tomorrow's ORM Today

The boys from Bryan are back and this time their talking about DataMapper, an ORM modeled after that other pattern by Martin Fowler. DataMapper is an alternative to ActiveRecord with some lofty goals of its own. Fast, thread-safe, and feature rich, DataMapper would be downright enterprisy, if it weren't for all the innovation they're cooking up. DataMapper is a primo example of an ORM that has evolved beyond the typical relational database setup.

Brian & Ben are partners in software consultancy specializing in Django, Rails, and Merb development. The team has closely followed the progress of both Merb and DataMapper since their respective 0.9 rewrites, contributing to the projects whenever possible. They use Merb + DataMapper as their primary web stack on all new projects.

Come on out and join us!

ORM Deathmatch!

by Mike Perham

ActiveRecord isn't the only game in town when it comes time to access your database with Ruby. We'll take ActiveRecord, DataMapper and Sequel, put them in a steel cage match to the death and see who emerges victorious. Attendees in the first three rows might get bloody so bring a poncho.

Mike is a Ruby developer at FiveRuns and faints at the sight of blood.

Sinatra - a Tiny Ruby Web Framework

by Damon Clinkscales

There are times when Rails seems like massive overkill, but you would still like to use Ruby goodness. This is especially true when your entire web site idea can be contained inside one file. We'll take a look at the features of Sinatra and play around with a sample application based upon it.

Damon is software engineer (doing mostly Ruby and Rails work since 2005) for VitalSource Technologies. He also recently created a Twitter/Flickr mashup called SnapTweet and is the leader of the Austin On Rails user group.
