The Universal Runtime for Embodied AI. Connect any AI model to any robot hardware through a single YAML config.
Runtime validation in type annotations
The article shows how Python’s typing.Annotated metadata can be used to attach runtime validators to type annotations and then automatically apply those validators when instances are created. It walks through extracting annotation metadata, handling callable validators, and improving error reporting so that annotated fields are validated and meaningful errors are thrown during object ini...
Visual Introduction to PyTorch
This article provides a visual, intuition-first guide to PyTorch, focusing on how tensors and computational graphs enable automatic differentiation. It strips away complex mathematical jargon to explain how the "Autograd" engine tracks operations to compute gradients for neural network training.
model-context-shell
Unix-style pipelines for MCP tools - compose complex tool workflows as a single tool call.
Type-based alias analysis in the Toy Optimizer
The post explains the basics of Type Based Alias Analysis (TBAA), a compiler optimization that uses type information to determine whether different memory accesses can alias, enabling more aggressive optimization. It walks through a simple “toy” example to make the concept concrete and shows how TBAA improves generated code by removing unnecessary load and store barriers.

So... Postgres is now basically a search engine? (And it's free)
This video demonstrates how to turn PostgreSQL into a powerful, personalized search engine using the open-source PG text search extension (based on the BM25 algorithm). It provides a technical walkthrough on using Claude Code and UV to build a Python-based system for scraping web content, tracking links, and managing a private knowledge base.
You Could've Invented OpenClaw
This tutorial walks through rebuilding OpenClaw, the open source AI agent, from the ground up, starting with a 20 line Telegram bot and ending with a fully functional mini version in about 400 lines, so you can truly understand the architecture by building it yourself.
