LLM Workflows then Agents: Getting Started with Apache Airflow
(github.com/astronomer)
This repository contains an SDK for working with LLMs from Apache Airflow, based on Pydantic AI. It allows users to call LLMs and orchestrate agent calls directly within their Airflow pipelines using decorator-based tasks. The SDK leverages the familiar Airflow @task syntax with extensions like @task.llm, @task.llm_branch, and @task.agent.

Shadowing in Python gave me an UnboundLocalError
(ntietz.com)
There's this thing in Python that always trips me up. It's not that tricky, once you know what you're looking for, but it's not intuitive for me, so I do forget. It's that shadowing a variable can sometimes give you an UnboundLocalError!

I Built Faster Reinforcement Learning in C# Solo Than Teams Did with Python
(rlmatrix.com)
The question comes relentlessly: “Why build reinforcement learning in C#?” Behind this query lies an unspoken assumption that serious machine learning happens exclusively in Python. This perspective reveals a fundamental disconnect between academic ML researchers with their sprawling Python scripts and those of us solving real industrial problems.

Tell HN: I forked and republished a popular, abandoned Python library
(ycombinator.com)
The `stringcase` package on PyPI [0] is fairly popular, on the order of 150k daily downloads [1]. However, there has been no sign of activity since June of 2023, and that was only to merge a pull request that breaks tests. The author's own last changes appear to have been a few days after the last PyPI release, in August 2017. A wheel was never distributed, despite being a single-file Python implementation with no dependencies.

Specializing Python with E-Graphs
(vectorfold.studio)
We've explored progressively more sophisticated techniques for optimizing numerical computations. We started with basic MLIR concepts, moved through memory management and linear algebra, and then neural network implementations. Each layer has added new capabilities for expressing and optimizing computations. Now we're reading to build our first toy compiler for Python expressions.
