Save your eyes, start using f.lux
This thing gets a lot of love by a bunch of folks here, so I gave it a good half year of trying.  But it's just too annoying.Around 5pm, your display turns pinkish orange and it becomes a lot harder to see anything.  Code gets harder to read, colors display wrong, video just fades to black.  None of the advertised happiness ensues.The second half-year it remained installed, my only interaction with it was to notice it screw up my display, then right-click the tray icon and disable it.Needless to say, I didn't install it on the new box I bought this year.  I don't understand why people like it.
