Quality you can’t generate: AI is only as good as your constraints

AI changed the cost structure of software. It didn't change the value structure. The value is no longer the code you write. It's the taste, judgment, and constraints you encode into the system that shapes what AI produces.

Double Takes

TDDing with Claude is like having a pair that removes all the failing assertions every time you go to the bathroom.

Steve Jackson

State machines are the answer for those seeking determinism in the era of AI agents.

Dave Mosher

A Slack conversation left Doc reflecting on what bug bashes say about the systems we work in.

Doc Norton

Test-driven development is to programming what double-entry bookkeeping is to accounting.

Neal Lindsay

The fundamental character flaw of the software creator is not the misguided belief that they can solve any problem with software. Instead, it is the belief they can understand how their own software works before they create it.

Steve Jackson

We may need a SaaS appendix for Zawinski's law:

Any SaaS platform attempts to expand until it is a social network.

Building software teams that manage mistakes rather than rejecting them
The software industry shares a pervasive assumption that expert developers don’t make mistakes. Developers are only human. They will make mistakes. Ignoring that means any mistake can lead to a high intensity event. There’s a better way. Invest in systems to manage inevitable mistakes.

Ratcheting to zero: How incremental constraints eliminate technical debt
How we made working with legacy code enjoyable: measure what you want to improve → automate it → make a change. Repeat. The demonstrable march toward improvement is what makes development satisfying.
