Last week I hinted at a demo I had seen from a team implementing what Dan Shapiro called the Dark Factory level of AI adoption, where no human even looks at the code the coding agents are producing. That team was part of StrongDM, and they've just shared the first public des...

Quoting Tom Dale

I don't know why this week became the tipping point, but nearly every software engineer I've talked to is experiencing some degree of mental health crisis.

[...] Many people assuming I meant job loss anxiety but that's just one presentation. I'm seeing near-manic episodes triggered by watching software shift from scarce to abundant. Compulsive behaviors around agent usage. Dissociative awe at the temporal compression of change. It's not fear necessarily just the cognitive overload from living in an inflection point.

Why don’t filmmakers just film on location instead of using visual effects? Lots of reasons, including not disrupting communities, control of weather & sun position, or can’t get permission.

“How did medieval French handwriting become ‘the Nazi font?’ And why did Hitler make it illegal?” TIL that Hitler gave a speech to the Reichstag about how much he disliked blackletter fonts.

Quoting Karel D'Oosterlinck

When I want to quickly implement a one-off experiment in a part of the codebase I am unfamiliar with, I get codex to do extensive due diligence. Codex explores relevant slack channels, reads related discussions, fetches experimental branches from those discussions, and cherry picks useful changes for my experiment. All of this gets summarized in an extensive set of notes, with links back to where each piece of information was found. Using these notes, codex wires the experiment and makes a bunch of hyperparameter decisions I couldn’t possibly make without much more effort.

Karel D'Oosterlinck, I spent $10,000 to automate my research at OpenAI with Codex
