Gregory Brown has been releasing a chapter a week from the Ruby Best Practices book. And, this week is no different, releasing a chapter on functional programming techniques. While this chapter may not be for the feint of heart, it certainly gives a broader and more technical scope to the topics already covered, such as, "Driving Code Through Tests," and, "Designing Beautiful APIs."
Matt Aimonetti put together a comparison, specifically covering the generation of XML from within Rails. And, while the XML Builder is fine for a lot of cases, he finds that for larger document generation, Nokogiri may be your better choice, performing up to four times faster than XML Builder in his examples.
Gregg Pollack just put up a list of Ruby and Rails conferences which are coming up in the next six months over on the Ruby on Rails weblog.

While simple, these Forms can be quite powerful and efficient. Dr. Nic uses it for managing a job application processes, while conferences organizers often use it for managing proposals.
Ever need to test a piece of your application to verify what happens after a certain period of time? Like, maybe when a book becomes overdue or a user's subscription expires.
