== DESCRIPTION: The RightScale AWS gems have been designed to provide a robust, fast, and secure interface to Amazon EC2, EBS, S3, SQS, SDB, and CloudFront. These gems have been used in production by RightScale since late 2006 and are being maintained to track enhancements made by Amazon. The RightScale AWS gems comprise: - RightAws::Ec2 -- interface to Amazon EC2 (Elastic Compute Cloud) and the associated EBS (Elastic Block Store) - RightAws::S3 and RightAws::S3Interface -- interface to Amazon S3 (Simple Storage Service) - RightAws::Sqs and RightAws::SqsInterface -- interface to first-generation Amazon SQS (Simple Queue Service) (API version 2007-05-01) - RightAws::SqsGen2 and RightAws::SqsGen2Interface -- interface to second-generation Amazon SQS (Simple Queue Service) (API version 2008-01-01) - RightAws::SdbInterface and RightAws::ActiveSdb -- interface to Amazon SDB (SimpleDB) - RightAws::AcfInterface -- interface to Amazon CloudFront, a content distribution service == FEATURES: - Full programmmatic access to EC2, EBS, S3, SQS, SDB, and CloudFront. - Complete error handling: all operations check for errors and report complete error information by raising an AwsError. - Persistent HTTP connections with robust network-level retry layer using RightHttpConnection). This includes socket timeouts and retries. - Robust HTTP-level retry layer. Certain (user-adjustable) HTTP errors returned by Amazon's services are classified as temporary errors. These errors are automaticallly retried using exponentially increasing intervals. The number of retries is user-configurable. - Fast REXML-based parsing of responses (as fast as a pure Ruby solution allows). - Uses libxml (if available) for faster response parsing. - Support for large S3 list operations. Buckets and key subfolders containing many (> 1000) keys are listed in entirety. Operations based on list (like bucket clear) work on arbitrary numbers of keys. - Support for streaming GETs from S3, and streaming PUTs to S3 if the data source is a file. - Support for single-threaded usage, multithreaded usage, as well as usage with multiple AWS accounts. - Support for both first- and second-generation SQS (API versions 2007-05-01 and 2008-01-01). These versions of SQS are not compatible. - Support for signature versions 0 and 1 on SQS, SDB, and EC2. - Interoperability with any cloud running Eucalyptus (http://eucalyptus.cs.ucsb.edu) - Test suite (requires AWS account to do "live" testing).

DecentExposure helps you program to an interface, rather than an implementation in your Rails controllers. The fact of the matter is that sharing state via instance variables in controllers promotes close coupling with views. DecentExposure gives you a declarative manner of exposing an interface to the state that controllers contain and thereby decreasing coupling and improving your testability and overall design.

A bold typographic theme for Jekyll, inspired by Swiss design.

Bitters helps designers start projects faster by defining a basic set of Sass variables, default element style and project structure. It's been specifically designed for use within web applications.

YamlDb is a database-independent format for dumping and restoring data. It complements the database-independent schema format found in db/schema.rb. The data is saved into db/data.yml. This can be used as a replacement for mysqldump or pg_dump, but only for the databases typically used by Rails apps. Users, permissions, schemas, triggers, and other advanced database features are not supported - by design. Any database that has an ActiveRecord adapter should work.

ROXML is a Ruby library designed to make it easier for Ruby developers to work with XML. Using simple annotations, it enables Ruby classes to be mapped to XML. ROXML takes care of the marshalling and unmarshalling of mapped attributes so that developers can focus on building first-class Ruby classes. As a result, ROXML simplifies the development of RESTful applications, Web Services, and XML-RPC.

The scrypt key derivation function is designed to be far more secure against hardware brute-force attacks than alternative functions such as PBKDF2 or bcrypt.

A modular scale is a list of values that share the same relationship. These values are often used to size type and create a sense of harmony in a design. Proportions within modular scales are all around us from the spacing of the joints on our fingers to branches on trees. These natural proportions have been used since the time of the ancient Greeks in architecture and design and can be a tremendously helpful tool to leverage for web designers.

Quickly bundle any Ruby libraries into a RubyGem and share it with the world, your colleagues, or perhaps just with yourself amongst your projects. RubyGems are centrally stored, versioned, and support dependencies between other gems, so they are the ultimate way to bundle libraries, executables, associated tests, examples, and more. Within this gem, you get one thing - <code>newgem</code> - an executable to create your own gems. Your new gems will include designated folders for Ruby code, test files, executables, and even a default website page for you to explain your project, and which instantly uploads to RubyForge website (which looks just like this one by default)

\Rainbows! is an HTTP server for sleepy Rack applications. It is based on unicorn, but designed to handle applications that expect long request/response times and/or slow clients.

Adds methods to DebugInspector to allow for inspection of backtrace frames. The debug_inspector C extension and API were designed and built by Koichi Sasada, this project is just a gemification of his work. This library makes use of the debug inspector API which was added to MRI 2.0.0. Only works on MRI 2 and 3. Requiring it on unsupported Rubies will result in a no-op. Recommended for use only in debugging situations. Do not use this in production apps.

It is a design pattern in key-value databases to use the key to simulate structure, and Nest can take care of that.

Rodauth is Ruby's most advanced authentication framework, designed to work in all rack applications. It's built using Roda and Sequel, but it can be used as middleware in front of web applications that use other web frameworks and database libraries. Rodauth aims to provide strong security for password storage by utilizing separate database accounts if possible on PostgreSQL, MySQL, and Microsoft SQL Server. Configuration is done via a DSL that makes it easy to override any part of the authentication process. Rodauth supports typical authentication features: such as login and logout, changing logins and passwords, and creating, verifying, unlocking, and resetting passwords for accounts. Rodauth also supports many advanced authentication features: * Secure password storage using security definer database functions * Multiple primary multifactor authentication methods (WebAuthn and TOTP), as well as backup multifactor authentication methods (SMS and recovery codes). * Passwordless authentication using email links and WebAuthn authenticators. * Both standard HTML form and JSON API support for all features.
