Director is a routing library for JavaScript that handles URL and command-line pattern matching across client-side, server-side, and CLI environments. It provides a unified approach to defining routes as nested object literals, where each key maps to a URL segment and its handler, supporting both hash fragment monitoring and the HTML5 History API for browser navigation without page reloads. The library distinguishes itself through its ability to operate in multiple contexts with a single routing paradigm. It supports asynchronous handler queue execution for sequential tasks like authenticatio

This project is a comprehensive collection of Python programming education materials, including tutorials, exercises, and curated code samples. It serves as a learning curriculum and software engineering toolkit, utilizing Jupyter Notebooks to combine executable code with descriptive educational text. The repository provides practical implementation guides for building large language model applications, such as retrieval-augmented generation systems, stateful AI agents, and machine learning workflows. It distinguishes itself by offering a structured approach to agentic coding workflows, cover

Arroyo is a high-performance stream processing platform built in Rust. It executes continuous SQL queries on streaming data with event-time semantics, enabling accurate windowed aggregations, joins, and stateful computations on unbounded event streams. The platform uses native Rust execution for high throughput and low latency, with periodic checkpointing for exactly-once fault tolerance and horizontal scaling across distributed workers. The system integrates deeply with Kafka for reading and writing topics with exactly-once delivery and supports change data capture (CDC) from MySQL and Postg
