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. https://x.com/dabit3/status/2021387483364151451

cysqlite - a new sqlite driver Charles Leifer introduces cysqlite, a from scratch DB API compatible SQLite driver he revived after pysqlite3 became harder to maintain and less compelling long term. The main focus is sane transaction handling that matches SQLite’s default behavior, avoids Python sqlite3’s confusing autocommit and legacy modes, and provides a cleaner base for SQLite extensions and Peewee integration. https://charlesleifer.com/blog/cysqlite---a-new-sqlite-driver/

Calling Lean Functions As Python Functions Philip Zucker introduces leancall, a Python library designed to bridge the gap between Lean 4 and Python by allowing Lean functions to be called as native Python functions. He demonstrates its utility through practical examples like balancing a Cartpole in a reinforcement learning environment and building a ray tracer, highlighting Lean's performance benefits while leveraging Python's va... https://www.philipzucker.com/leancall/

Rewriting pycparser with the help of an LLM Eli describes how he used an LLM coding agent (Codex) to help rewrite the popular Python C parser pycparser, replacing its old PLY based parser with a hand-written recursive descent parser that passes the full test suite and is easier to maintain. He found the experience efficient and insightful, noting the agent did most of the heavy work in far less time than doing it manually while hi... https://eli.thegreenplace.net/2026/rewriting-pycparser-with-the-help-of-an-llm/

Stop Building Ugly APIs: Use the Fluent Interface Pattern The video walks through refactoring a small Python animation API from a clunky configuration style into a fluent interface that reads like a story using method chaining and domain specific methods. It also explains what the fluent interface pattern is, how it differs from the builder pattern, where it already appears in Python, and when it is appropriate or inappropriate to use. https://www.youtube.com/watch?v=f1Nb_JV_s8Y
