How we optimized Dash's relevance judge with DSPy Dropbox used DSPy to turn prompt engineering for our relevance judge into a measurable, automated optimization loop, improving task performance, cost, and how reliably it works in production. https://dropbox.tech/machine-learning/optimizing-dropbox-dash-relevance-judge-with-dspy

Using Claude to fix PyPy3.11 test failures securely This post describes using Claude to assist in fixing PyPy 3.11 test failures, with all generated changes run in a sandbox and verified locally. It highlights a practical workflow where AI suggests patches but humans validate results, enabling faster debugging without sacrificing safety. https://pypy.org/posts/2026/03/using-claude-to-fix-pypy311-test-failures-securely.html

Python Type Checker Comparison: Typing Spec Conformance When you write typed Python, you expect your type checker to follow the rules of the language. But how closely do today's type checkers actually follow the Python typing specification? In this post, we look at what typing spec conformance means, how different type checkers compare, and what the conformance numbers don't tell you. https://pyrefly.org/blog/typing-conformance-comparison/

Deploying AI Models with Hugging Face – Hands-On Course This tutorial is a comprehensive, end-to-end guide to the Hugging Face ecosystem, showing how modern AI moves from research ideas to real, deployed systems. Rather than focusing on a single model or task, the course presents Hugging Face as the operating system of modern AI—connecting models, datasets, libraries, demos, and deployment into one coherent, practical workflow. https://www.youtube.com/watch?v=R8h_gpSpEVU

Lessons from Pyre that Shaped Pyrefly High-performance type checking at Meta required a performance-first architecture and tight integration with developer workflows, enabling fast, incremental analysis at massive scale. The key lesson is that large Python codebases adopt typing successfully through gradual, low-friction tooling that prioritizes developer ergonomics and fast feedback over strict correctness. https://pyrefly.org/blog/lessons-from-pyre/

Pydantic AI intro - Agents and Instructions! In this video, we'll take a look at Agents in Pydantic AI, and will create a simple Agent that can be run synchronously and asynchronously. We'll explore how to inspect agent outputs, and how to amend outputs using instructions that are passed to the LLM. https://www.youtube.com/watch?v=XyGHYG7QNK0
