f.lux beta (another thread)
-
@hsiktas well they are using the same code, finally. Things to check:
- same wake time
- same location
- same presets
- https://justgetflux.com/timesync.html looks similar?
It turns out my Mac and PC are about 8 kelvin apart (testing during the fastest portion of the bedtime transition), but they are also about 7 seconds apart too.
The next update may shift the wake timing a bit, so there might be some skew until we update the Mac. But right at this minute for you, they should be the same.

@herf
I had indeed different wake times on both machines and I just adjusted them. This seems to solve my problem. :) -
Pushing 4.25 via auto-update, to get everyone testing the newer code. I definitely have bugs filed for all the things in this thread too!
Thanks everyone.
-
@hsiktas and I just shifted the wake transition earlier so "fast transition" people should not wake up to an orange screen. However, at night the Mac and PC should still be the same. Glad to hear you got it. :)
-
I'm not sure if I'm too early, but it's not automatically updating for me. I have 4.24.

@herf Hey I just installed 4.25, thanks for support DisplayLink Monitors! That was a deal breaker for me! (I still used Flux but the DL monitor had a custom color setting to match my primary monitor at 2900K)
Bugs
Only one I found so far: when prompted for UAC in Windows 10 v1607 build 14393.1066) ,flux will instantly show the blue colors on both displays as long as the UAC prompt is up.This also happens at the lockscreen. So there is a little bit of inconsistency when working at night as my lockscreen is at 6500K and when I am prompted for UAC for opening programs or scripts that require Admin rights

@herf With the new release I just had installed, I very clearly see the future for this program and your other projects: You and Lorna (and probably other people working with color controlled lights) want to make it abundantly clear to avoid or reduce light after / near sunset as much as possible. The "vignette" mode really makes this obvious!
I do appreciate your specific example, and I'm still in school, but I don't have to get up early for that, it's for other reasons and it's not mandatory. I remember you talked about a phase shift versus a stronger light / dark cycle and I'd a bit of education about what you're describing. My understanding of this topic only involves regulating light / dark timing, so bright light during the day, etc. So, what is a phase shift?
Thank you, it's great to see you both on the forums, it does seem you've got a bit more free time not working as much on the beta now that you've got it working. You and Lorna are very helpful and it's just incredible how much you all can help explain some of information about light and sleep, and we keep learning more (and I'm sure your research is non-stop so far). I am just in awe of how much there is to learn about all this, I never thought I'd learn so much about what seemed a very simple topic.
-
I did a Performance Test (just noticed the button there) and I got 64 - 70% dropped frames at 60FPS. Is that normal? Feels like a lot. Would you recommend disabling f.lux during gaming then?
-
How are you guys getting 4.25? It's not automatically updating for me.

Same here. This beta has opened my eyes to one simple fact: this is an extremely deep rabbit hole.

It auto updated here without any problem. I just quitted f.lux and launched it again.
Btw, one bug, that was already present in build 4.24 at least, can't tell about the previous ones. When the screen goes to "sleep mode" aka AFK, when i return to PC and the monitor powers back on, f.lux has daytime temperature. I am forced to click on f.lux icon in the taskbar to bring it to foreground in order to get back the right temperature.
-
@caydenly this is a common result now, since GPUs are synchronizing with the backlight. In this version, we have done a lot of optimization to send as few commands as possible, because dropped frames at 60hz are hard to avoid now. (Before the power saving efforts of the past couple years, this stuff was totally free and never dropped frames ever.)
Also, for gaming, you can use our "very fast" transition setting, so the number of times we will touch the GPU is low.

Yeah, I exited f.lux 4.24 several times. I right-click the icon and choose "Exit f.lux".

@Tungsten_smooth Well, we don't know the answers yet -- in particular a lot of people need better ("more") light exposure during the day (which involves screens too, because we work in offices that are too dark to accommodate them). The first part of our job with f.lux is to think up hypotheses and motivate people to test them. The vignette feature is based on some recent research, and I'll write down the idea sometime soon.
But the main work we're doing is to make models and test them in the real world (not just have people believe they're all true).
Regarding your question about phase vs amplitude:
Phase
Most people think of the circadian system ONLY in terms of phase - e.g., we would call a night owl "phase delayed" and an early bird "phase advanced". This means that their internal clock is offset from the solar time by a certain amount.
So when you are a night owl who wants to wake up earlier, you want to "advance" your system by seeing more light in the morning and less at night. And the reverse for an early bird who wants to sleep in. As such, a lot of our users tend to be night owls. But you might think this is the end of the road for circadian topics - is your phase aligned with how you want it to be?
Amplitude
What is clear from experiments on shift workers and the elderly (and many rodent models) is that the overall circadian rhythm in the body can be suppressed. In some cases, it's operating at a lower "amplitude" because light and dark are not clearly defined or not happening at the right times. For instance, people who spend time in natural lighting during the winter have an enormous melatonin amplitude thorughout the night (you can see melatonin in the blood lasting 14 hours), whereas most of us in the modern world are living in a "perpetual summer" and we have a relatively small melatonin duration in comparison to natural conditions.
We think some sleep problems (and some immunity and seasonal effects) depend to some degree on the "strength" of the circadian rhythm, not just whether it's phase aligned. (Of course, a misaligned rhythm, e.g., in shift work, will almost always have a reduced amplitude, so they are somewhat related.)
Also, not all sleep trouble is circadian, so when we can, we look for ways to help people get to bed on time. It is probably true that we could do a lot of good here that's completely unrelated to magic science and more to human behavior.

It was still just v4 before.
Mike got the automatic update working for me just now though!

@TwoCables Rabbit hole is exactly the way we talk about this - once you fall in, you realize there isn't a bottom. But first you have to fall in....

@herf
Hi ,
just installed the new "beta" version ..initially it's a bit confusing.. but I think I have my "old" settings back. My Anti-virus did not like the installer ? I agreed /approved that the file was legit but that is something you might need to work on, overall I tend not use the settings at all once the program is installed .. "set and forget " is my motto.suggestions ,
- see if you can get back to the old UI .. the waves on the screen make it very confusing , something compact and neat ?
- I dunno what they are , the line " light is making your body earlier. means a big huh to me ?
- change waking time to working time .. ( unless we have people that roll out of bed while working)
- no help ? not even a link or a help file ? ( maybe could explain how it works and the settings )
aside from that its good, I have pointed several people to this who work late in the night and most of them give raving reviews ..
-
Wow. Great job with the new software mouse cursor! No reboot required! Now we no longer need to use any tricks.

I don't know if this was just a one-off glitch, but I was taking the color temperature down and up with the hotkeys and somehow got it into a situation where it just wouldn't stop going up. It was at somewhere like 70,000K before I ended the f.lux process and restarted it (when I restarted, it was at something like 18,000, which was more manageable to get back down to where it was, especially since it wasn't going up anymore). I've noticed there's an 800 lower bound, but is there an upper bound when using the hotkeys?
