Sometimes people ask us what bugs cost. In this case, the answer seems to be: 40 weeks of engineer time, per quarter, at google salaries. But hey, this was a great read!

We stopped roadmap work for a week and fixed 189 bugs
Discussed on Hacker News, lobste.rs and r/programming
It’s Friday at 4pm. I’ve just closed my 12th bug of the week. My brain is completely fried. And I’m staring at the bug leaderboard, genuinely sad ...

We absolutely cannot wait for @wickstrom.tech to turn our foundational technology loose on a bunch of UIs.
UPDATE:
After 18 months of sitting out a noncompete, I'm finally back working on generative testing. Not only that, I'm joining @antithesis.com next week, and I can't wait to build testing technology with such a deeply technical and committed group.
Everything in its right place.

The latest episode of the #BugBash podcast has @qianli.dev from DBOS talking about the hard truths of ergonomics. As always, if it ain't easy, it probably won't happen.

Couldn't agree more. And with more and more of our time spent specifying software anyway as we start working with LLM copilots, there's a natural dovetailing of approaches.
Property-based testing to me feels like a really good point in the testing/formal methods design space. PBT is rigorous in the sense that you're writing a spec of some kind, while being easy to understand and not having much of the chaotic behavior that characterizes heavyweight formal methods

Gonna keep the boring corporate announcement short.
Antithesis now allows you to orchestrate with the same Helm chart you use in production. #kubernetes!
Until a few weeks ago, you could only use docker-compose. It seems slightly silly to say, but it's true.
