Using patents is frowned on. Given the existing system, it's silly not to participate. It's not a case where a boycott would help, and by holding the patent you ensure that no one else uses it against you.

> and by holding the patent you ensure that no one else uses it against you. A - Wouldn't they be protected due to f.lux being prior art? B - Would a competitor be able to get a patent on this in the first case? (due to A)

We all know that prior art can be missed when issuing a patent -- I'd assume having it already in the patent system makes that less likely to happen, and easier to deal with when it does happen.

I'm not sure what you mean by "Linux is not Windows" in this context. In my experience, most installs of Windows these days (Windows 7 and Windows 8) are 64-bit installs. That's what is sold at Best Buy on their desktops and laptops for example. On the contrary, when a user goes to install Ubuntu, they're recommended to use 32-bit. When I'm on forums, people mention compatibility problems with 64-bit Linux and recomm…

Do you remember Firefox trying to cancel 64-bit build for Windows? Stating they have a lot of extra bugs in it? In Windows they still run 32-bit software on 64-bit OS, but a typical Linux install will have not a single 32-bit program. That's why not having a 64-bit version is pathetic.

In fact, the majority of software installed on my 64-bit Windows 7 system is 32-bit. Sad.

Why use f.lux when you can just pop a metatonin pill thirty minutes before sleep? I've been doing that and I sleep like a baby every night regardless of how long I stare at my bright monitor beforehand.

How does staring at a bright screen affect sleep? If anything, it makes me tired and I fall asleep even faster.

This thing gets a lot of love by a bunch of folks here, so I gave it a good half year of trying. But it's just too annoying. Around 5pm, your display turns pinkish orange and it becomes a lot harder to see anything. Code gets harder to read, colors display wrong, video just fades to black. None of the advertised happiness ensues. The second half-year it remained installed, my only interaction with it was to notice it…

Whenever Flux gets mentioned, there's two groups of people: 1: Doesn't understand it, hates the "wrong" colors. Can't get used to it. 2: Appreciates the candle-like colors, says it helps them sleep in the evening or relaxes their eyes. I wonder if there's some sort of genetic difference? Maybe some people just aren't sensitive to bright light in the evening?

I had to make the night time colors much cooler for me to be able to tolerate it. I felt like the default was far too red.

For all my fellow f.lux windows fan, I created a little app (in Delphi) : Reflux. You can download it here (There is also another package with source) https://skydrive.live.com/redir?resid=CD51CF0B626581E!134&#3... Basically, you can configure it to kill f.lux (and thus get your precious color back) when certain applications are executed. When all the "killer" applications are closed, f.lux is restarted automatically…

Nice to know someone is still using Delphi :) I had a lot of fun with it as a kid.

I wonder if there are also geographic differences at play? I love it during summer in Germany (= bright until ~10PM) but it annoys me when it turns dark at 4PM, while I am still at work.

I live in London and I have my location set to Recife, Brazil. That way I get 'sunset' around 9pm in the winter - late enough to let me continue working on a bright screen, but early enough to not blast blue light before going to bed.

The point for me is not so much matching the environment but not staring at a blue screen right before bed.

I love f.lux. It does take a bit of getting used to, but if you wait it out, you'll enjoy it. And, the research they've done on light is quite impressive too: http://stereopsis.com/flux/research.html That being said, this has been around for a while, so I wonder why it's trending now. They haven't put out any recent updates afaik

I just wish it would go based on ambient light if you have a webcam rather than what the sun is doing. Where I work, I'm not always exposed to natural sunlight, and I don't always work during the day going into the night where I'm going to want my screen to adjust to me trying to fall asleep halfway through a second-shift schedule.

It's hard to measure ambient light correctly for something like this, because in a dark room, most of the ambient light is actually coming from the screen itself.

If you happen to have a /sys/class/backlight/acpi-video0/brightness file on your system (e.g., linux laptop). Here's a light weight and easy to customize option.

First make this file writable.

    chmod o+w /sys/class/backlight/acpi-video0/brightness
Then add something like the following to your crontab. I'm constantly doing this manually, and never thought to crontab it until this article.

    0 17 * * * echo 14 > /sys/class/backlight/acpi_video0/brightness
    0 18 * * * echo 13 > /sys/class/backlight/acpi_video0/brightness
    0 19 * * * echo 12 > /sys/class/backlight/acpi_video0/brightness
    0 20 * * * echo 11 > /sys/class/backlight/acpi_video0/brightness
    0 21 * * * echo 10 > /sys/class/backlight/acpi_video0/brightness
    0 22 * * * echo  9 > /sys/class/backlight/acpi_video0/brightness
    0 23 * * * echo  8 > /sys/class/backlight/acpi_video0/brightness
    0 00 * * * echo  7 > /sys/class/backlight/acpi_video0/brightness
    0 05 * * * echo 12 > /sys/class/backlight/acpi_video0/brightness
    0 06 * * * echo 13 > /sys/class/backlight/acpi_video0/brightness
    0 07 * * * echo 14 > /sys/class/backlight/acpi_video0/brightness
    0 08 * * * echo 15 > /sys/class/backlight/acpi_video0/brightnes
Note: 15 is the max brightness for me, not sure if that is standard, just cat the file to see your current level of brightness.

Well, you can use f.lux too. I prefer redshift because of its CLI nature.

Does anyone else here use f.lux on Linux? I installed the Ubuntu version but not only does the "pause/unpause" option sometimes do nothing at all but other times it simply forgets to change the colors.

I tried f.lux a month or so back on Xubuntu, and it just flat out wouldn't work for me. So I tried redshift, and it worked just fine.

I wonder if the two groups are 1. the ones who discovered the "Slow" setting in preferences, and 2. the ones who didn't. When the transition is set to Fast, I find it very jarring. When it's set to slow, I barely notice it.

So you're proposing that everyone should like it?
