It's truly humbling and uplifting to receive a photo from someone with both of your books on their desk, along with the message: "I got my own copy of A Beginner’s Guide to LangGraph and AI Agents and found it very useful and well-written."

This article has one of the best ideas I’ve read recently. Moral of the story: don't compete with AI on marginal improvements & instead, do things it cannot do. Knowledge work is dying, welcome to the age of wisdom work!

LLMs with their NLP features are becoming the UI! You won’t need to wrestle with Excel menus or formulas anymore. You can just say something like, “What’s the average of the top half of the salary column?” and via some MCP style tools you should get the result.

Think of LLMs the way you think about DBs. For some cases, a simple like SQLite is ideal; for others, you need a behemoth like Oracle. Context determines the right fit. Bigger isn’t automatically better & smaller, local models will play a bigger role soon.

This tip in VS Code / Cursor made my life better. Setting a 5-second delay between when you stop typing and when the code completion appears gives you time to think and makes AI-assisted coding much more enjoyable. Thanks @stefanjudis.com for the ideea!

✍️Pen and paper are becoming a lost luxury! When preparing podcast questions, I’ve found it more enjoyable to take YouTube transcripts, run them through an LLM for formatting, then study & highlight them in print. Less screen time, better focus.

I got tired of figuring out how to add an MCP server over and over to various clients...so I've built mcp-add.
A CLI that knows the right questions to ask and where to put the info in most clients.
You can run it in interactive mode with `npx mcp-add@latest` or by passing args to do it in one go!

RAG is the most economically impactful application of gen AI. Cursor & Claude Code are, at their core, RAG systems. For example one of Cursor improvements comes from using embeddings to predict where the cursor should move on next. Details in this talk by Jason Liu:

AGENTS.md is a simple, open format for guiding coding agents. Think of it as a README for agents.

Saying we don’t need to learn to write because LLMs can do it is like saying we don’t need to go to the gym because machines can lift for us. Writing is for the mind what exercise is for the body.
