Most of my work is writing good instructions. Here's the prompting style that works for me, and the handful of skills that earn their place.Thu, 04 Jun 2026 17:00:00 GMThttps://techblogogy.vercel.app/posts/fixing-a-hot-moldy-garage-with-an-esp32/https://techblogogy.vercel.app/posts/fixing-a-hot-moldy-garage-with-an-esp32/The garage was an oven by midday and started growing mould. A $10 microcontroller pretending to be the AC's remote, a schedule, and a temperature log fixed it without buying a smart AC.Thu, 14 May 2026 16:40:00 GMThttps://techblogogy.vercel.app/posts/ricing-linux-by-prompting-claude/https://techblogogy.vercel.app/posts/ricing-linux-by-prompting-claude/Omarchy gave me a great starting point.
