Field notes

Notes

Short accounts of decisions made while building: a rule I needed to reconsider, instructions I could no longer trust, or a correct result the interface did not make clear.

Too heavy, and I could not say which notes

A piano accompaniment sounded too heavy, and I could not point to the notes. Finding them through conversation and listening, changing only those, and discovering that the score had already said something similar.

The instinct to compress

I almost wrote aggregation logic to save a few dollars a year on S3. The impulse was real. The savings were not.
