this is a very cool lib,

Rails 2.3 has a ton of really nice functionality locked up in monolithic components. I’ve posted quite a bit about how we’ve opened up a lot of that functionality in ActionPack, making it easier to reuse the router, dispatcher, and individual parts of ActionController. ActiveModel is another way we’ve exposed useful functionality to you in Rails 3.

Generate syntax-highlighted slides from Markdown

An ActionMailer delivery method to save mails as files in a directory.

So you downloaded inaction_mailer, and you had a folder full of e-mails generated while writing your app?

Large scale server deploys using BitTorrent and the BitTornado library.

So here’s an overview of how things are going to work in Rails 3.

Easily show multiple, overlapping events across calendar days and rows.

The Ruby Koans walk you along the path to enlightenment in order to learn Ruby. The goal is to learn the Ruby language, syntax, structure, and some common functions and libraries. We also teach you culture. Testing is not just something we pay lip service to, but something we live. It is essential in your quest to learn and do great things in the language.

Ruby Ghostscript (RGhost) is a library for document developers wanting a quick and easy way to generate pdf files. It's optimized to work with larger documents.

Capybara sets up some tags for you to use in Cucumber. Often you’ll want to run only some scenarios with a driver that supports JavaScript, Capybara makes this easy: simply tag the scenario (or feature) with @javascript:

Underscore is a utility-belt library for JavaScript that provides a lot of the functional programming support that you would expect in Prototype.js (or Ruby), but without extending any of the built-in JavaScript objects. It's the tie to go along with jQuery's tux.

This is a group devoted to making JRuby a first-class application language for Android.

Imagine all the syntactical delights of Ruby and Haml for your JavaScript. You write in a nice language, but get normal JavaScript at runtime. All whilst having full access to 3rd-party JavaScript libraries (jQuery, PrototypeJS), debugging support (it becomes pure, readable JavaScript), existing support from test suites (it’s normal JavaScript) and growing support from various text editors (TextMate, Vim, Emacs).

If we want mobile applications to stay around as a sustainable business, we need to be more honest about the strengths and weaknesses of a touchscreen UI, rather than salivating about an imaginary realm of unnamed possibilities.

Though we ended up switching to what I consider to be a technically superior product based on simplicity, we arrived there because of poor community interaction on the part of the Bundler developers.

Unfortunately vanilla Ruby modules lack support for many idioms popular in modern Ruby. Most importantly, we have become accustomed to composing our classes with meta-programming macros such as has_many, validates_presence_of or after_save. And modules weren't built with macros in mind.

I love Cucumber, but I hate writing step definitions. They are ugly, awkward to write and very, very boring: Most step defintions merely create objects for a scenario to chew on.

Pretty print your Ruby objects with style -- in full color and with proper indentation
