I can't wait for Opus to be trained to use t.TempDir() and t.Cleanup() in its next version.
Using context.Background() in unit tests is so go1.23 aka 2023.

Twitter is similar to walking in the metro. You end up having to ignore noisy drug addicts lying on the floor.

I made my coding agent container "md" work with Android's ADB so now I can have my coding agent build and push an android app to my phone over wifi, all from within a docker container!
This is both incredibly dangerous and pretty cool.

If I had an infinite amount of free time I'd get one of these and implement bluetooth heart rate monitor support (HRM BLE). That'd be really nice. I wonder if someone is crazy enough to attempt this kind of project.

All day, many of you have been asking for a Cheney obituary from me. Get ready:

I'm trying to find the formal documentation for the type "Error" in @typescriptlang.org website and can't find it!
