A curated hands-on tutorial collection to learn systems by reimplementing technologies from scratch.

PostHog delivers an integrated product analytics platform—event capture, session replays, feature flags and experiments—suitable for teams needing self-hosting or cloud options while keeping data control.

This project is an open, practice-oriented textbook and knowledge base that systematically integrates maths, computer science and AI topics and includes an MCP server for local integration and teaching deployment; however, unclear licensing and low community/release activity warrant careful evaluation before adoption.

Hallmark is an LLM design skill for Claude, Cursor, and Codex that generates self-contained HTML/CSS pages using macrostructures, 20 themes, and 57 quality gates—suited for teams needing portable design templates and controlled AI output; however, repository activity and compatibility should be evaluated before production use.

The GitHub Copilot SDK provides multi-language agent runtime and tool integration to embed Copilot workflows in applications; however, license and maintenance details are unclear—verify legal and activity status before production adoption.

This repository collects Anthropic's 'Code with Claude' hands-on workshops covering model selection, multi-agent design, memory and evaluation—useful for learning agent engineering and eval-driven development—but it is declared unmaintained and heavily relies on Anthropic services, posing migration and long-term use risks.

Bonsai-demo is a local-deployment demo repo offering quantized Bonsai/Ternary models and multi-backend run scripts to test vision-language capabilities and agent tool-calling on phones, GPUs, or CPUs; however, verify licensing, private-model access, and community/maintenance visibility before production use.

Protocol Buffers provides high-performance, language-neutral binary serialization and code generation (protoc) for microservices, mobile and cross-platform data interchange; prefer released commits and verify license compatibility before enterprise adoption.

code-review-graph builds an incremental code-structure graph with Tree-sitter to compute change blast-radii and minimize the context AI reviewers must read; suited for large repositories seeking to reduce token/read costs and integrate with CI/IDE.

DocuSeal: open-source PDF form builder and automated e-signatures.

Open Interpreter is a Rust-based Codex derivative coding agent that uses switchable harnesses and local sandboxing to optimize low-cost models for real-world code generation and automated testing, suitable for developers and teams wanting local agent deployment.

turbovec provides a TurboQuant-based trainless vector index that delivers high compression and low-latency local search, tailored for RAG and embedding retrieval use cases sensitive to privacy, memory, or latency.

DeepTutor centers on an agent-native architecture that combines TutorBots, persistent memory, and RAG knowledge bases to deliver an extensible personalized tutoring and collaborative workspace—well suited for autonomous learning, teaching automation, and knowledge-driven conversational education products.

An open-source cross-platform video editor rewrite targeting creators and developers: Rust core with a plugin-first design to enable desktop/browser/mobile parity, scripting, and headless automation. Currently in active rewrite and unstable—suited for technical early adopters and integration experiments.
