Announcements In 2001, experts called Wikipedia a "joke," a "do-it-yourself encyclopedia," and a "vandal's playground." Today, it's the gold standard for factual baseline information on the internet. Are Large Language Models (LLMs) following the exact same trajectory? In this new essay,...

(view in browser) Jul 29th Dear Reader, Welcome to the July 29th edition of the Data Science Briefing. Announcements Put your old Mac to work serving a local LLM. Running a language model on your own hardware costs nothing per token, works on a plane, and never sends your code elsewhere. On Apple Silicon it's fast too — unified memory is a large part of why Mac Minis are back-ordered for weeks. This post covers the whole path: install llama.cpp, pull a GGUF, and serve it over an...

(view in browser) Jul 22nd Dear Reader, Welcome to the 328th edition of the Data Science Briefing. Announcements Ready to level up your understanding of AI agents? 🤖 AI agents are only as effective as the systems that orchestrate them. While most discussions focus on choosing the right model or writing better prompts, the real challenge is building a harness that can manage context, coordinate tools, recover from failures, and execute complex workflows reliably. A well-designed agentic...
