Yes, we will cache this feed. In the meantime I don't think this is causing physical I/O because the feed is small and should be in cache. But we don't like doing any more system calls than necessary.

Choose "Classic f.lux" from the color selection menu in the f.lux window. Set the color to 1200K. Or, you can also set it to 800K using the keyboard shortcuts, which you can enable if they're not enabled by going into the f.lux options and turning on "Use these hotkeys to control f.lux". Change your location to somewhere in the world where the sun has already set or risen so that it's opposite you. So, if you're doing this at a time between sunrise and sunset, choose a location that's between sunset and sunrise. Change the color temperature to 1200K (or, again, you can try 800K as well). Now it no longer matters what your location is set to or what time of day it is because this sets f.lux to the exact same color temperature for both day and night, which means it will never change on you ever again - unless, of course, you change it again.

Here is the schedule f.lux gives me.

We are not totally opposed to fun! But nice explanation of the feature! I think the main question here is that we are trying to do things that seem like they will still work in 5 years, and a lot of the ways to hack into the system to do things like this seem to get limited more over time. FWIW, I think even our mission of helping sleep can be served by doing things that are more behavioral and less physiological - e.g., if we make a change that convinces you to look up and realize you are tired, it may be just as effective as dimming the screen.

@User_V1 Reinstalling via Windows solved my issue, thanks alot for the compilation, youre my hero of the day :3!

@kaitlynrobert The program is designed to reduce eye strain during night-time use, helping to reduce disruption of sleep patterns. If you are Not understand it then visit: motherboard guru

Longtime flux user, just upgraded to Macbook Pro (14 inch, running iOS 12.0.1). Flux is green! I will look at workaround, but wanted to let you know that it continues to be a problem. Thanks.

Yeah, night driving is the worst.

yeah, I guess so, they are literally outdated.

I agree that this would be a very important feature to have. Even in the summer, when the sun hardly sets here at all, I'd still like my computer to cue me at 8pm that it's time to start getting sleepy

Many people dim using f.lux's software dimming (using full backlight brightness). So you get less contrast but less flicker this way. Alt+PgDn does this.

awesome.

Nevermind! I spoke too soon. The issue was with a piece of anti-malware software. Sorry for the bother..

This is an option right below the Hue setting called "Allow f.lux to keep this computer awake to adjust lights." You are welcome to turn it off, but it won't work as well. Also, we do this only when the computer is plugged in (or has a nearly-full battery).
