I just launched a new gem named Scribble.

Scribble is a client facing template language similar to Liquid. Scribble was written in Ruby and can be used in any Ruby or Ruby on Rails project. It takes a template file, consisting of text and Scribble tags and transforms it into text. Scribble can be used to transform any plain text format like HTML, Markdown, JSON, XML or plain text. Client facing means that it is safe to use Scribble to run/evaluate user provided templates.

Ru brings Ruby's expressiveness, cleanliness, and readability to the command line. It lets you avoid looking up pesky options in man pages and Googling how to write a transformation in bash that would take you approximately 1s to write in Ruby.

For example, to center a file's lines, use: ru 'map(:center, 80)' myfile.

There are plenty of reasons users will want to sort and reorder lists, but implementing such a feature when using the has_many :through association isn't so obvious. In this post I'll show you how this is possible using the ActsAsList gem, and along the way show you how to load seed data, create a has_many :through relation, and use the great table_print gem. Read the post.
Almost every SaaS product has a free trial period. Why? At first, I thought it's to get as many people to try the product, but that doesn't make sense. The real reason is to create an "endowment effect."
Have you ever wanted to pass a method to a function that only takes a block? Or figure out which of your object's superclasses broke the method you're trying to call? Those things are easy to do with the method method. Use it well, and you can learn about your dependencies, save yourself hours of debugging, and get your code to the places it needs to be.
rb_import adds an import method to the Ruby VM so one can do foo_class = import './foo.rb'.

Tail call optimization is an optimization where tail recursive functions are transformed into loops by the compiler. A tail recursive function is one where the final statement is a call to the same method. In this post, we will look at what tail recursive functions look like, how tail call optimization helps them, and how to enable TCO in Ruby. [Continue reading]
Let Austen Ito show you how he builds a basic infrastructure with Docker, Chef, and Rails!
Location-based web applications calculate distance between objects using the latitudinal and longitudinal coordinates and the Haversine formula. But how does one determine an object's coordinates given a street address or IP address, let alone calculate the distance between two sets of coordinates? Fortunately the Geocoder gem turns these otherwise complex tasks into a fairly trivial matter. In this post I'll show you to to integrate Geocoder into your Rails application.

When you generate a scaffold in Rails, you'll see the usual respond_to blocks. But some of your actions, like index, don't have them. And those actions, when hit with a bad format, will raise the wrong kind of error. You want to handle bad formats correctly, but littering all your controllers with big respond_to blocks is crazy. It feels un-Rails-ish. So what do you do?
An example of dependency inversion
