AWS SDK for Ruby
AWS SDK for Ruby
Get started quickly using AWS with the AWS SDK for Ruby. The SDK helps take the complexity out of coding by providing Ruby classes for many AWS services including Amazon S3, Amazon EC2, DynamoDB, and more. The SDK is provided as individual downloadable packages for each AWS service, which include code and documentation. The SDK is also available through Ruby Gems. Version 3 of the AWS SDK for Ruby modularizes the monolithic SDK into service-specific gems, for example, aws-sdk-s3 and aws-sdk-dynamodb. Now each service gem uses strict semantic versioning, along with the benefits of continuous delivery of AWS API updates. With modularization, you can pick and choose which service gems your application or library requires, and update service gems independently of each other. You will need to configure credentials and a region, either in configuration files or environment variables, to make API calls. It is recommended that you provide these via your environment. -

Pro Git
Pro Git 2nd Edition
Welcome to the second edition of the Pro Git book. The entire Pro Git book, written by Scott Chacon and Ben Straub and published by Apress, is available here. All content is licensed under the Creative Commons Attribution Non Commercial Share Alike 3.0 license. Print versions of the book are available on Amazon.com. What is “version control”, and why should you care? Version control is a system that records changes to a file or set of files over time so that you can recall specific versions later. For the examples in this book, you will use software source code as the files being version controlled, though in reality you can do this with nearly any type of file on a computer. If you are a graphic or web designer and want to keep every version of an image or layout (which you would most certainly want to), a Version Control System (VCS) is a very wise thing to use. -

Gumroad
Sell stuff and see what sticks
This repository contains the source code for Gumroad’s e-commerce platform, exposing how a modern creator-focused storefront and payments system is assembled. The app models products, variants, subscriptions, and checkout flows, then ties them to fulfillment, licensing, and customer communications. It implements typical marketplace concerns—order management, refunds, discounts, taxes, fraud checks, and analytics—through well-defined services and background jobs. The UI offers product pages, carts, and dashboards for creators to manage listings and see performance, while APIs/webhooks enable integrations with external sites and automation. The codebase demonstrates practical patterns for multi-tenant architecture, permissions, testing, and asynchronous processing at scale. For engineers, it’s both a working marketplace and a study in how to balance flexibility for creators with reliability in payments and delivery. -

Ruby
Ruby programming language
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. -

CocoaPods
The Cocoa Dependency Manager
CocoaPods is a dependency manager for Swift and Objective-C Cocoa projects. It has over 82 thousand libraries and is used in over 3 million apps. CocoaPods can help you scale your projects elegantly. CocoaPods is built with Ruby and is installable with the default Ruby available on macOS. We recommend you use the default ruby. Using the default Ruby install can require you to use sudo when installing gems. Further installation instructions are in the guides. CocoaPods manages library dependencies for your Xcode projects. The dependencies for your projects are specified in a single text file called a Podfile. CocoaPods will resolve dependencies between libraries, fetch the resulting source code, then link it together in an Xcode workspace to build your project. Ultimately the goal is to improve discoverability of, and engagement in, third party open-source libraries by creating a more centralised ecosystem. -

Faraday
Simple, but flexible HTTP client library, with support for backends
Faraday is an HTTP client library abstraction layer that provides a common interface over many adapters (such as Net::HTTP) and embraces the concept of Rack middleware when processing the request/response cycle. You probably don't want to use Faraday directly in your project, as it will lack an actual client library to perform requests. Instead, you probably want to have a look at Awesome Faraday for a list of available adapters. The best starting point is the Faraday Website, with its introduction and explanation. This library aims to support and is tested against the currently officially supported Ruby implementations. This means that, even without a major release, we could add or drop support for Ruby versions, following their EOL. Currently that means we support Ruby 2.6+. You can also install the faraday_middleware extension gem to access a collection of useful Faraday middleware. -

Reverie
