Not the same person, but I keep a text file divided into two sections - "history" and "today"

The "today" section is a bulleted list of the things I think I'm working on today. I add to it through the day as I get shoulder-tapped, or as I realize another important sub-task.

As I finish tasks, or at the end of the day, I move them up into the "history" section under the current date. Thursday: A, B, C

This is basically all of the "head state" in the infamous cartoon of how you ruin engineers lives by interrupting them. I feel that it allows me to be interrupted without losing import state, and it's also a ready-made "scrum status" of what I did yesterday, and an augment to my memory when someone asks me "did you change X?" for some micro-task that was too small to ticket.

I feel this has helped me be a more effective developer, in spite of my decaying memory, than I was when I tried to keep everything in my head. :)
