I, and I'm sure the rest of HN, loves F.lux...but is there a reason why this needs to be posted every month or two? There hasn't even been an update (and the promised OSX update is no where to be seen)
Most important. Desktop. Utility. Ever.<p>I'm surprised of how few people even in our industry know about it. There hasn't been a single case where I show it to someone and he/she wasn't impressed. I'm so accustomed to using it that if for some reason it stopped working I believe my productivity would suffer at least 40%. Especially for those long winter hours it's a life saving app.<p>Where's the damn donate button?
F.lux (or something similar) is one of those things that should come pre-configured with each operating system. I find it indispensable for coding at night (and I use Photoshop quite a bit, too.) Shame there isn't a way to do this on iOS without jailbreaking.
I love the confidence of F.lux's domain name. "JustGetFlux.com" -- it's like: "why is this even a question?" Judging from most of these comments, I'd say we're all in agreement.<p>I definitely make a habit of telling everyone I know, especially when I happen to be looking at their screen at night.
My major pain with f.lux is the inability to manually specify when it should start shifting colours. I work in a brightly lit office until way after the sunset (esp. in winter), and it makes no sense for my screen to start colour shifting at 5PM.<p>My current 'solution' is simply manually starting f.lux when I get home, and killing it when I go to the office. Tedious!
I have some questions / issues before I blindly use this software:<p>1) It's not open source, or is it? I don't see anything about getting the source. In today's world, utilities like this are open source, or have an open source alternative. This is something that runs in the background of my computer all day, every day, so I would like to know what's going on.<p>2) How does this affect graphic design? Does it make it impossible to get colors just right?<p>3) Why does this matter? My lights are on in my office. It's ALWAYS the same brightness in my office, all the time. Daytime. Nighttime. I don't really understand what my monitor is adjusting to. Is it JUST that my eyes are probably more sensitive when I'm tired? If so, that makes sense I suppose, but how does it know that I'm tired just based on the time that I'm using my computer?<p>Anyway, I'm not trying to be negative, these are just the questions I have and the reasons why I haven't jumped on the bandwagon yet.
I'm conflicted... my eyes give me a ton of issues and this is tempting, but I also do a lot of front end work and visual design. I don't want everything I design at night to turn out blue because my screen was orange when I made it. I think for now I'll stick with my computer glasses, they've helped a ton.
Does anyone have a solution for using F.lux + Shades?<p><a href="http://www.charcoaldesign.co.uk/shades" rel="nofollow">http://www.charcoaldesign.co.uk/shades</a><p>If I run them simultaneously my monitor flashes yellow-and-normal.
Don't install this, it's a trap.
Spent 30min to reset the lightness/contrast/gamma of my 2 desktop screens using these painful OSD buttons.
Nobody should EVER use any computer without this. And, Apple is evil… because their proprietary walled-garden iOS censors out F.lux (among other things).<p>For those using GNU/Linux, use Redshift instead: <a href="http://jonls.dk/redshift/" rel="nofollow">http://jonls.dk/redshift/</a>
