For me personally, I code late at night because it's the only time during the day when I can truly be distraction-free. No incoming emails, no meetings, no phone calls, no running into people. Coding happens best when you can concentrate for long periods of time [1], and the best time to concentrate is when the rest of the world is asleep. YMMV.

I totally agree with that, 100%.

I just wish I didn't have to get up again in the morning.
