Spending time with my girlfriend. Usually trips around the Bay Area (it's amazing what's there within an hour's driving distance), dining, cooking (it's actually more expensive then dining out, but well worth it in terms of using exactly the ingredients that you want), movies. Coding. Right now I am an airport (waiting for a flight) implementing something (a CS concept) I've implemented at work in Java, in OCaml just to refresh my knowledge of OCaml (and my understanding of what I actually did). I'll write toys just for fun of it, for myself. It's okay to re-invent the wheel if you have to, do it for enjoyment. Reading. Can be technical, can be non-fiction, can be fiction. Presently I am reading Richard Rhodes' Dark Sun and Benjamin Pierce's Types and Programming Languages. Keep in mind that your brain is a lot like a heap of a run-time with generational garbage collection or a log-structured file system / database. Occasionally, the throughput at which you can write and read information from it goes down as it moves the bytes around and deletes the un-needed stuff. If you never let it do that, you'll run out of space / your knowledge will become incredibly fragmented. It's important that if if you don't feel like being productive (read: your NewGen is full) you shouldn't force yourself to be. Go for a walk, watch a movie, work out, go out and eat (even if by yourself). I wonder how much money companies lose due to the rule or convention that one should work in a single contiguous chunk during the day (sitting comatose at their screen, when they should be taking a nap or going on a walk).
