AI in Practice

What actually worked, what did not, and what it cost - from real projects rather than from announcements, with the failures left in.

    Lighthouse now grades your site for AI agents

    Lighthouse has a fifth category, Agentic Browsing, and one of its audits reads your llms.txt. Three sites failed it for the same undocumented reason, and the API will not give you the category unless you ask for it by a name that is not in the docs.

  • Diagram: four labeled failure cards -- a matched filename, dev server timing, an invented test fact, and a plausible-sounding wrong answer.

    Four ways an AI agent was confidently wrong on a migration

    Each of these looked right. A filename match that paired the wrong screenshot with the wrong article, a dev server that made correct code look broken, and a test that wrote down facts it did not own.

    What the build caught that nobody was looking for

    Automated gates on a 150-page migration found a dropped screenshot, thirty redirects pointing at nothing, and an orphan hidden by a regex wildcard. None of it would have been found by reading pages.

  • Diagram: three pairs of reported-versus-observed numbers, each a mismatch between a claimed measurement and what was actually true.

    Measure it in a real browser

    A simulated 2,061ms render delay that did not exist, an image library silently ignoring the font it was given, and a contrast failure that was a misread value. Three cases for checking directly.

  • Diagram: two columns, judgment and communication skills that still belong to a person, against boilerplate and first drafts that are increasingly automated.

    Tech careers for students, with AI in the room

    So many young adults and high-schoolers seem to be disheartened with the rise of AI in tech. Those young minds who LOVE to write code are being dissuaded to even bother studying the art of software development and…
