Akhil Bansal has created a cool bash script that will create a new Rails project, import it to an SVN repository, then remove and ignore log files, sessions, temporary files, and set up database.yml correctly.

Mark A. McBride has put together a great article about processing credit cards with Ruby on Rails using the Active Merchant plugin.

In case the title of this post is giving you deja-vu, we've looked at "How To Create A Ruby Extension In C" before at Ruby Inside. We've also looked at using RubyInline to make the process even faster by not having to write a specialized C extension.

Bruce Tate continues his fine Crossing Borders series with a look at Ruby's support for closures. If code blocks and block techniques used by routines such as Rails' respond_to confuse you, it's a great primer.

Russ Olsen has been putting together a small series of blog posts about building a DSL in Ruby.

In the mini-series, Russ looks at the motivation for developing a DSL and develops a basic DSL called Potemkin.
