Dailyish note today posted: https://divisionbyzero.net/notes/2026-05-29/
Most of the content is a lesson I learned at Booking.com: Own your differentiators. I'm _SO_ fucking sick and tired of cloud and SaaS for everything. Owning and running your own infrastructure is not that complicated and is _FAR_ cheaper than leasing it from hyperscalers.
Maybe this is why I'm so opposed to AI? On premise, self-hosted, owned infrastructure companies I worked for kept their OpEx's below 40%. The SaaS/Cloud heavy infrastructure companies I worked for had 80-100% OpEx costs. This is not a coincidence!
