Surely F.lux is fairly pointless unless the only source of light in your room is your computer monitor?

I would imagine that any windows or external lighting is going to have a far greater effect than F.lux. I tried F.lux a while ago when it was recommended in a previous HN post but for me the only difference it seemed to have, was to make my computer monitor more difficult to read by making it too dim.

Just tried it again. Still can't live with it at night, makes me feel like I am going blind with the shift to red. Might try it 1 more time with a gradual shift and see if that works but right now, certainly not useable for me.

I couldn't stand F.lux the first time either. What I did was set it to where I could barely tell the difference. After a week or so I would find myself thinking "too bluish" staring at my screen at night, at which point I lowered the color temperature slightly.

Within two months, I had found a setting I felt comfortable at (right now it's at 3500K).

Actually. Staring at a screen until midnight, the screen is a major light source.

Also for me, my desk lamp automagically dims from 11 to 1pm, just to make me feel a little more sleepy.

Do you mean 11pm to 1 am?

[hmottestad]

yes :)

F.lux has not been fairly pointless for me. I am sure of that.

It's had some helpful effects for me, even when I have other lights on. The computer is what I'm spending the whole time looking at, after all.
