F.lux makes the color of your computer’s display adapt to the time of day

Can't recommend this enough.

However, I forget it's on at night. When editing images and colors for webpages, I always go insane the next day when I forgot to turn f.lux off and all the colors are completely off.

Yeah, it's not ideal for colour-sensitive graphic work like that. I'm a coder, so when I picked this up a few months ago it was wonderful.

The only issue I have is that it locks up the entire computer while it fades gamma down at sunset, and again at sunrise. Maybe that's intentional, to let you know that sunset's arrived?

From the FAQ: "Q. This changes too fast, it always shocks me. A. The f.lux transition can be CPU intensive, so f.lux tries to be polite about it. To make it slow, you can use the special 1-hour slow transition option under settings instead."

That's a nice option to turn on.

This has been a lifesaver for me, since I like to come home from work and poke at side projects until 11pm or midnight a couple nights a week.

Since I started using F.lux, I actually feel tired at that hour of the evening and fall asleep when I go to bed.

Have you been more or less productive with your side projects? I'm wondering if getting more sleep produces more code than the college-style all-nighter hackathons over a long term.

I produce less code, but better code. Usually if I stay up really late, whatever I worked on after 1 or 2AM ends up being a throwaway. At that hour the logical abilities in my brain have gone to sleep even if I haven't.

I'll come back to the project later and wonder what I was thinking. Then I'll take a mulligan, revert whatever nonsense commits I made after midnight or so, and start over to write it the right way. So all I've done is waste a few hours of good sleep.

Also, if I was up until stupid o'clock working on something on one night, I'm not very likely to want to work on it the following night. That loss of momentum is really the biggest thing that can hurt me, as I need constant successes to keep me motivated.

I've been using flux on multiple machines for a year or more and I love it. The interface is simple and intuitive. I recommend it to everyone, at least to try out for a while.

There's a button you can press to turn flux off for an hour for when you're doing color-sensitive work at night, too.

F.lux changes the color temperature. It's the difference between using fluorescent bulbs and incandescent bulbs... significantly reduces eye strain at night.

I've been using this for nearly a year now and it takes me under 30 seconds to get used to the color change when it occurs.

I agree. The only time I notice my colors are "off" is when I'm sitting there when it transitions. Even when it transitions I just say "Oh, I didn't expect that right then" and go back to work as normal.

I love F.lux, I just wish there were a (jailbroken) version for the iPad.

There is, I'm using it, and we'll ship it soon. :)

CONGRATULATIONS. This exists since over a year.
