This repository turns invoice-style Excel data into Neo4j nodes and relationships with pandas, then shows how to convert graph relationships into matrices. It preserves a legacy py2neo v3 and Neo4j 3.x teaching path while adding a modern example with the official driver, vector indexes, and GraphRAG-style retrieval. Current Python and Neo4j environments may require changes to the pinned legacy code.

This repository contains the hands-on exercises for a RubyConf workshop on building basic desktop applications with Ruby and Glimmer DSL for LibUI. Learners install the gem, run the included examples, and progress through interface tasks, MVC architecture, and optional application scaffolding on macOS, Windows, or Linux. It is instructional workshop material designed to accompany a presentation and video, not an end-user desktop application.

Learn how an agent gateway grows from a basic model loop into a routed, proactive, and resilient system. Ten progressive Python sections add tool use, sessions, Telegram and Feishu channels, routing, memory, cron work, durable delivery, retries, and concurrency, with matching English, Chinese, and Japanese code and documentation.

100ProjectsOfCode is a categorized collection of hands-on programming ideas ranging from web and networking tools to applications, AI, computer science, cryptography, and games. Pick a project, create a repository, implement and test it, then use the finished work as a portfolio piece before moving to another challenge. Many entries include suggested languages, tools, or example implementations, although that guidance is still incomplete in places.
