Everything here is written for developers who know one thing well and are learning the next one. Pick the line that sounds like you.
“I write Python. I’ve been avoiding SQL.”
Read the SQL for Python Developers series in order. It uses DuckDB, so there’s nothing to install beyond pip install duckdb, and every example runs on data you generate yourself.
- I know Python; why learn SQL?
- Run your first SQL query in under 5 minutes
- SQL thinks in sets, not loops, the post that makes the rest click
The series page tracks which posts you’ve read.
“I want AI that runs on my own machine.”
- Run AI locally with Python: uv + Ollama is the setup. Twenty minutes, no API key.
- The Queue Is Full: what I’m building next with local-first AI is where it leads.
“Tell me what actually happens when AI writes the code.”
I Vibe Coded and Lived to Tell is the honest version: real tools, small models, what broke. Start with the promo generator and then read The Makefile Was Lying to Me.
“I take a lot of notes and get little out of them.”
- Karpathy’s LLM knowledge base method: why it works and how to start.
- Your notes need metadata: the small habit that makes notes queryable.
“I’m studying for an AWS exam.”
The AWS Data Engineer Associate series is the unfiltered account: a fail, a pass, and what changed in between.
Prefer email? New posts come to you, with a few notes on what I’m reading and building.
