Could You Run This Yourself? A Practical Way to Know What’s Safe to Build with AI, and What Isn’t (opens the original)
Read excerpt
You’ve probably tried it already. Opened Claude or ChatGPT, asked it to write a script that would clean up a messy spreadsheet of customer contacts, watched it produce code you couldn’t read, and closed the tab, unsure whether what it built even worked.In the work I’ve done with clients on this, that’s usually the moment things stall, because there’s no way to know whether to trust an answer you can’t evaluate yourself.Mindful AI with Andreas Lehner is a rea
The web page that passed every test and failed in every browser (opens the original)
Read excerpt
The job this week was a new website for an ESG consultancy in Germany. Standard build, with one twist in the brief: their team wanted to edit the site’s content themselves, no developer in the loop. So the project includes a small content editor they log into through the browser. The public site ships as plain static files served from Cloudflare, which is what keeps it fast and close to free to run.Everything worked.

It also wasn’t doing much: hard to update without help, invisible to search, frozen in whatever state it was last touched.Before bringing anyone else in, the owner had already tried to move things forward alone, using claude.ai. No code written by hand. In an afternoon, a new single-page site existed: a menu, sectio
The task she did a dozen times a week - and never once questioned (opens the original)
Read excerpt
Every time a coaching client of mine booked a call with one of her prospects, she’d open Google Calendar, fill in the time and fill in the title, click “Invite via link,” copy that link, and paste it into whatever LinkedIn DM or WhatsApp chat she was already in.Six steps minumum, a dozen times a week.
