Taming computers since 1980. Now taming wild AI agents. Interested in harnesses, memory systems and all that jazz.

This last 30 days I have 3 agents running full time in the background doing specific tasks for me. Openclaw is the generalist one, it runs all experiments, all dirty things I just prompt and fuck it. It is my entry point. When I am golden about what I want I code a structured one

30 looks like the moment when then generation speed is reasonable for coding.

And I am yet to use ssh integration and claude teams integration

Testing cmux today. I'm pretty impressed at the moment. I've been, for a long time looking for a way to keep all my terminals in the same window so I can make this mix fine with aerospace.

Some small features that make is worth it: 🧵

Vertical tabs for workspaces and horizontal tabs for different things inside that workspace. That two dimensional way of thinking is killer for me.

One side effect of being an AI first company is that everyone will start pinging your API through claude or whatever harness you want in the most crazy ways.

Even if the API is internal only.

Having safety nets is more important than ever.

@GermanDZ Oh god. I am waterfall now!

[Rafa de Castro @rafadc]

Agents have made documentation more valuable than ever. We document not only how the application is supposed to behave but how the new code is supposed to be written. That is more important than ever.

[Rafa de Castro @rafadc]

I have the feeling that the more I work with agents the more my job is to find a good feeback loop. A feedback loop is just to define the initial state, define how to iterate to the goal and define how to find if you are closer to that goal or further.

It still bites me everytime but it is because I cannot still understand that if there is a football match I cannot pull a docker image.

This is the internet we want.

i havent laughed at a video this hard for years lmao

@garrytan I ended up having a spare ssh tmux session with pi where I ask him to fix the config up to a point where it works.

I am moving a lot of files using claude code. I'm done.
