Building robots, especially for household chores, can be a lot of fun! Ben is working on an autonomous WiFi robot that can take out trash using a Raspberry Pi. In this Part 1 video, he walked through how he manually controls the robot (like a remote control) and shared the Python code he wrote to make it work.

R.E.D.: Scaling Text Classification with Expert Delegation
Text classification is a classic use case of supervised learning, but it gets tricky when you're dealing with too many classes and only a small amount of training data per class. Using LLMs might seem like a solution, but the token costs can add up quickly. That’s where the R.E.D algorithm comes in. In this article, Aamir Syed dove deep into how it works and shared code you can use to get started.

Python Adopts Standard Lock File Format for Reproducible Installs
PEP 751 was officially accepted on March 31, 2025, marking a major leap for Python’s packaging ecosystem. Similar to how JavaScript, Rust, and Go rely on lock files like package-lock.json, Cargo.lock and go.sum, Python will now have a standardized lock file format. This change is a big win for creating reliable, reproducible environments - especially crucial for deployment and CI workflows. If you're curious about what this PEP introduces, why it matters, and the benefits it unlocks, check out this article by Sarah Gooding from the Socket team.

In this tutorial video, Justin from CodingEntrepreneurs walks you through building your own data pipeline and crafting an Analytics API from scratch. He used Python, FastAPI, SQLModel, SQLAlchemy and TimescaleDB and also demonstrated how to deploy the project on the Railway platform. It’s a great resource if you’re looking to learn the full flow - from development to deployment.
