Script is a collection of scripts and rule-sets designed for iOS proxy tools to modify mobile application behavior, filter network traffic, and automate interactions with online services. It provides a library of scripts and a network filter to manage how applications communicate with web services. The project enables the unlocking of premium features, memberships, and VIP content within third-party applications. It also allows for the bypass of geographical restrictions on downloads and the removal of advertisements from mobile application interfaces. The toolset covers the automation of we

Faraday is an HTTP client library for Ruby that sends requests and processes responses through a middleware pipeline with pluggable adapters. Its core identity is built around a middleware-pipeline architecture where HTTP requests and responses flow through a chain of components that can modify, log, or transform data before reaching the backend, combined with an adapter-based backend abstraction that delegates HTTP execution to interchangeable backends like Net::HTTP or Typhoeus. The library distinguishes itself through a parallel-execution engine that dispatches multiple HTTP requests concu

This project is a static analysis tool and linter for Ruby on Rails designed to identify architectural smells and violations of best practices. It serves as a code quality linter, architectural auditor, security scanner, and performance analyzer for Rails applications. The tool evaluates the separation of concerns between controllers, models, and view templates to reduce technical debt. It identifies suboptimal coding patterns and enforces stylistic consistency, while specifically scanning for security vulnerabilities such as unprotected mass assignment in models. The analysis surface covers

This project is a Java technical interview guide and markdown-based knowledge base. It provides a collection of curated study materials and common interview questions designed for developers focusing on the Java ecosystem.
