I find this like really really strange for quit a few reasons. For me the most productive time to program is after 21:00 hours. The weird part is this even if i sleep like a baby and i come to work i will be productive but not nearly as productive and INTO programming as i am after dark : P
The weird thing is even if i come from work and school so tired i can barely keep my eye's open if i will sit down behind a screen i will suddenly change moods from tired to like freaky focused.
Night seems to go really well in hand whit programmer, anyone else effected by this whatever it is xD
