    Metasploit Framework

    Metasploit Framework

    Metasploit Framework

    Metasploit Framework is a comprehensive penetration-testing and exploit development platform that streamlines the process of discovering, validating, and demonstrating vulnerabilities. It provides a modular architecture—payloads, encoders, exploits, auxiliaries, and post-exploitation modules—so security professionals can piece together complex attack chains or test defensive controls in realistic ways. Built-in features include an exploit database, network scanners, credential harvesters, and frameworks to craft reliable payload delivery while handling target nuances like mitigation bypasses and platform differences. Beyond raw exploitation, the framework includes post-exploitation tooling for lateral movement, persistence, data exfiltration simulations, and evidence collection, enabling red teams to exercise detection and incident response workflows.

    Pro Git

    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.

    Jbuilder

    Jbuilder

    Generate JSON objects with a Builder-style DSL

    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.

    Errbit

    Errbit

    The open source error catcher that's Airbrake API compliant

    Errbit is a tool for collecting and managing errors from other applications. It is Airbrake API compliant, so if you are already using Airbrake, you can just point the airbrake gem to your Errbit server. The way Errbit arranges notices into error groups is configurable. By default, Errbit uses the notice's error class, error message, complete backtrace, component (or controller), action and environment name to generate a unique fingerprint for every notice. Notices with identical fingerprints appear in the UI as different occurences of the same error and notices with differing fingerprints are displayed as separate errors. Following the recommendation of 12factor.net, Errbit takes all of its configuration from environment variables. You can use dotenv, which is included in the Gemfile, to fill in any values that you can't or won't supply through the environment.

    Gumroad

    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.
