Open Source Ruby Formats and Protocols

Jbuilder gives you a simple DSL for declaring JSON structures that beats manipulating giant hash structures. This is particularly helpful when the generation process is fraught with conditionals and loops. You can either use Jbuilder stand-alone or directly as an ActionView template language. When required in Rails, you can create views à la show.json.jbuilder (the json is already yielded). Fragment caching is supported, it uses Rails.cache and works like caching in HTML templates. If your collection cache depends on multiple sources (try to avoid this to keep things simple), you can name all these dependencies as part of a block that returns an array.

A dynamic, open source programming language with a focus on simplicity and productivity. It has an elegant syntax that is natural to read and easy to write. Ruby is a language of careful balance. Its creator, Yukihiro “Matz” Matsumoto, blended parts of his favorite languages (Perl, Smalltalk, Eiffel, Ada, and Lisp) to form a new language that balanced functional programming with imperative programming. He has often said that he is “trying to make Ruby natural, not simple,” in a way that mirrors life. Since its public release in 1995, Ruby has drawn devoted coders worldwide. In 2006, Ruby achieved mass acceptance. With active user groups formed in the world’s major cities and Ruby-related conferences filled to capacity. Ruby-Talk, the primary mailing list for discussion of the Ruby language, climbed to an average of 200 messages per day in 2006. It has dropped in recent years as the size of the community pushed discussion from one central list into many smaller groups.

This is a modified version of the CRC algorithms by Lammert Bies. It supports more algorithms and has been ported to several languages. It's also useful for learning how to do hexadecimal calculations and bitwise operations in various programming languages. Disclaimer: These test programs demonstrate the calculation of CRC. I made these translation with a basic knowledge of each language. They may or may not be appropriately formatted / secured / robustified / idiot proofed or any similar programming issues.

There's been a lot of churn around AMS since it began back in Rails 3.2 and a lot of new libraries are around and the JSON:API spec has reached 1.0. If there is to be a 1.0 release of AMS, it will need to address the general needs of serialization in much the way ActiveJob can be used with different workers. The next major release is in development. We're starting simple and avoiding, at least at the outset, all the complications in AMS version, especially all the implicit behavior from guessing the serializer, to the association's serializer, to the serialization type, etc. The basic idea is that models to serializers are a one to many relationship. Everything will need to be explicit. If you want to serialize a User with a UserSerializer, you'll need to call it directly. The serializer will essentially be for defining a basic JSON:API resource object: id, type, attributes, and relationships.

A richly featured XML tool-kit for Ruby, based on the Rails ActiveRecord API.

Alba is a JSON serializer for Ruby, JRuby, and TruffleRuby. Alba is easy to use because there are only a few methods to remember. It's also easy to understand due to its clean and small codebase. Finally, it's easy to extend since it provides some methods for override to change the default behavior of Alba.

The Amazon DynamoDB Session Store handles sessions for Ruby web applications using a DynamoDB backend. The session store is compatible with all Rack-based frameworks. For Rails applications, use the aws-sdk-rails gem. The session store is a Rack Middleware, meaning that it will implement the Rack interface for dealing with HTTP request/responses. This session store uses a DynamoDB backend in order to provide scaling and centralized data benefits for session storage with more ease than other containers, like local servers or cookies. Once an application scales beyond a single web server, session data will need to be shared across the servers. DynamoDB takes care of this burden for you by scaling with your application. Cookie storage places all session data on the client side, discouraging sensitive data storage. It also forces strict data size limitations. DynamoDB takes care of these concerns by allowing for a safe and scalable storage container with a much larger data size limit.
