Building an End-to-End Development Environment to Deploy AI Solutions
Three accounts, AWS, GitHub and Claude Code, connected once, turn a chat in your terminal into a live app on your own domain. A step-by-step Hello World, and how to control spending, centralise billing and scale. Also in Spanish.
From MATLAB to Databricks: What Nine Years of Python Put Into Thirteen Notebooks
A free thirteen-notebook course, from data structures to PySpark and a Kaggle capstone, and the road behind it: notebooks that became giant calculators, pandas running out of room, and Spark's recipe-before-cooking idea.
A Noise Monitor That Knows the Local Law
A Raspberry Pi measures dB(A) to sound level meter definitions, keeps the loud nights as tamper-evident clips, and finds the noise limits for its own street: national law, regional decree and town ordinance combined minute by minute.
Neural Networks 1001: A Course Honest Enough to Say When a Technique Didn't Help
Nine runnable notebooks from a single neuron to a GPT, all trained on a laptop CPU, and four textbook claims that came out differently when run as experiments.
LiDAR, Satellites, and a Party Wall: Building a Real GeoAI Pipeline
A real multimodal building-extraction pipeline: LiDAR point clouds, Sentinel-2 imagery, and OpenStreetMap ground truth, with a polygon-level evaluation that a row of shared-wall townhouses exposed for real.
Two Features That Didn't Work, and a Battery That Doesn't Exist
Building an AI energy trading platform on real Spain OMIE prices — a walk-forward backtest that's more honest than a single train/test split, two negative feature-engineering results kept in the repo instead of hidden, and a battery-arbitrage optimizer with nothing real to optimize yet.
Teaching an Agent to Read a Wind Farm
A LangGraph agent, real SCADA data from two open UK wind farms, and a physics equation from 1919 catch a sensor fault that a dashboard alone would have missed — and why the whole thing ended up self-hosted on AWS for under $0.10/month.
Do Whales Move Bitcoin? Building an Analytics Demo Honest Enough to Say "Not Sure Yet"
Real BTC price and on-chain data, a full scan of real recent Bitcoin blocks for whale transactions, a generalized ESD anomaly test, and a correlation check that came back "not enough overlapping data" instead of a manufactured headline.
