Field notes

What we learn
by building.

Operations, systems and applied AI, told from the inside. Each note comes from a problem we solved at a company and is reviewed by the person who built the system.

Multi-tenant: the error you can't see

Isolating each company's data in a single database looks solved until it isn't. Why fixing the search_path isn't enough and where to really look.

How a field note gets written

Every note comes from a system that is running.

  1. 01

    A real problem

    It comes from an implementation: something we saw fail, measured or solved inside a company.

  2. 02

    Writing

    It is written with the person who solved the problem, from their notes and the system logs.

  3. 03

    Technical review

    The person who built the system reviews it. If a fact cannot be verified, it is not published.

  4. 04

    No calendar

    We publish when there is something worth telling.
