Hands-On Modern RL

Reinforcement learning is no longer just about teaching a virtual cart how to balance a pole; it is now the secret engine behind alignment in large language models. The open-source curriculum hands-on-modern-rl bridges this gap by taking you from classic control baselines all the way to advanced techniques like direct preference optimization and agentic systems. Instead of heavy math walls, you get highly practical code chapters covering everything from standard training loops to multi-turn reasoning and tool use. It is the perfect, straightforward roadmap to understand how modern AI systems actually learn to think and act.

📦 sethgammon/citadel

Citadel

Citadel acts as an operating layer that turns chaotic AI coding chats into structured engineering workflows. If you use tools like Claude Code, your session context usually vanishes the moment you close the window, forcing you to re-explain your architecture every single time. This clever project solves that by saving persistent campaign memory directly inside your repository. When you type a request, its smart router classifies the task for free using pattern matching before resorting to expensive model calls. It even spins up parallel agent fleets in isolated worktrees to safely handle massive refactors. It is the perfect sanity-saving upgrade for hands-on developers.

📦 nasa/spacewasm

SpaceWASM

SpaceWASM is the flight-compliant WebAssembly interpreter that safely runs binary code on-board spacecraft. Built by NASA and Caltech, it compiles standard WebAssembly into a specialized intermediate representation designed specifically for the absolute reliability needed in deep space. Because space missions have zero room for memory failures or sudden software crashes, this interpreter enforces a custom, completely deterministic memory model using fixed-size pages and strictly bans runtime panics. It even decodes code on the fly in a single pass to save critical memory. It is a masterclass in adapting modern, portable web technology for the most extreme, resource-constrained environments in the universe.

📦 clickhouse/raytracer

Raytracer

Developers have built a fully functional 3D path tracer entirely out of ClickHouse SQL queries. There are no external programs or plugins here; a single database SELECT query calculates every single pixel, rendering glass-like chrome lettering floating over a procedurally generated landscape. It treats pixels as database rows, calculates complex 3D math on database tuples, and runs mirror-bounce loops using array functions to keep everything running in parallel. While other database engines struggle to even compile a scene like this, this clever hack whips through a gorgeous high-resolution image in under eighteen seconds. It is a brilliant, slightly chaotic reminder of just how powerful database engines can be when you...
