Portland Ruby Brigade

The Portland Ruby Brigade, also known as pdxruby and pdx.rb, is a user group for Ruby programmers in the Portland, Oregon area. The group welcomes all programmers interested in the language and its implementations, tools, libraries and frameworks, such as Ruby on Rails. The group has been meeting since August 2002 for presentations, demos and discussions applicable to all skill levels, from newbies and experts. Every month 100+ people come together to share their knowledge, projects and enthusiasm for Ruby – join us!


There are many ways to participate in pdxruby:
