I was wondering if anybody uses and seen any actual results in use F.lux (http://stereopsis.com/flux/) I use my computer late at night quite a lot and the lighting in the room I use my iMac is not great. Although the iMac does adjust its brightness to the ambient lighting in the room I was wondering if this program actually does help your eyes late at night.

I just started using it about a week ago and I love it. It seems weird and "red" at first, but that's the point, red light doesn't interfere with melatonin production and sleep and stuff. I no longer have that painful squinty moment if it's dark and I come back to the PC, because it doesn't blind me with the full spectrum anymore. It does have the option to easily disable if you're working on something colour-sensitive. Highly recommend.

How to know that f.lux works:

1) Use f.lux for a week.

2) Disable f.lux at 11 pm

3) Be blinded by the intensity of your suddenly very-blue screen.

Before flux, your eyes endured that every night.

set the at night mode on 4000k at first. I installed secretly on my mom's pc and set the gradient to 1 hour. She never noticed it.

a friend mine swears by it (he is a developer) and he will be up late working on code.

I personally cannot stand it because it yellows out what I am working on.

There's a mode where you can disable it for an hour in case you're an artist or something.

I have night mode at 4200k. It the difference in color was noticeable at first but not once I got used to it.

I don't think I've ever seen an attempt at doing a study on the effectiveness of the program though. It could the placebo effect everybody is experiencing like those magic bracelets..

I use it constantly to read a lot of pdfs... just put the "disable for an hour" option and see how it hurts the eyes when there is to little light and screen is at max bright.

I have f.lux on my jailbroken iPhone 4 and I love it. After using it for awhile, it seems like non-corrected screens at night are bright florescent blue bulbs. I believe it does help me fall asleep faster (in that using a non-corrected screen at night kept me up longer).

OR you could all just run your screens at the proper warm color setting instead of the terrible wrong colors cold setting every monitor, OS and tv is set to by septa dared today.

Turn down contrast, turn down brightness, set to warm color. Enjoy comfortable proper colors n your screen.

It does seem that the whole industry is trying to convince me that blue is the new white....

No, I wouldn't describe it as a placebo. People who use it are always struck by the odd colors at first but then they find that they like the adjustment into the evening. If someone "likes" what it is doing, and it is doing *something*, then it will have net-positive effect and that can't be chalked up as placebo.

If installing f.lux didn't make an obvious change at all to anything but claimed to do something and people agreed that it did "something" then that might be placebo.

How effective is it for sleep patterns? Idk exactly. I think it helps but it is probably hard to isolate. As other have said, use it for a week, turn it off and make observations about how your eyes feel. When I do that, my eyes feel more stressed looking at the default white balance than the adjusted white balance f.lux provide. That's not a placebo, that is real nerves firing in my eyes and sending signals to my brain.

It makes my screen look like an old CRT that some old guy has smoked 60 a day in front of

Easier on the eyes, yes, easier on the brain, no.

Plus my LCD doesn't have great viewing angles so the top looks brown and the bottom looks yellow

I'm a designer, my monitor is calibrated exactly as it should be and this program makes a hell of a difference at night when the computer is used for development or reading. Couldn't live without it. If i hit the disable for an hour button now, i can feel my eyes reel back in horror.

I've been using it for over a year now and it's one of the first apps I download on a new Windows install.

If it's excessively yellow, just bring it up to 4300k (fluorescent). It depends on the monitor you use it on. Also, for new users, change the setting from 20 seconds to 60 minutes, it's easier on the eyes the first few days.

It's definitely not placebo though, the difference is quite dramatic after using it for an extended period, I am now unable to live without it.

(Maybe I'll just try to disable it for a second and see if it's still workinokopol?,iasdf?oasdmfsa OH GOD IT BURNS!)

You're supposed to set the temperature of your monitor to match the ambient lighting, warm matches incandescent bulbs (that turn everything yellow) and cool should match the colour of daylight (and fluorescent lighting if you got the right bulbs).

That said, on my monitor "normal" matches daylight while cool does turn everything slightly blue, so I just don't think they have any idea.

    • That is $130 more than I paid for my 4TB a year ago. How is this a deal?
    • JetBrains' new AI-first 'IDE' JetBrains Air is now on Windows by David Uzondu JetBrains has announced that JetBrains Air, its Agentic Development Environment (ADE) is now available for download on Windows x64 and ARM. You might not be familiar with JetBrains Air. It's this new desktop app that the company launched back in March 2026 to let developers hand off tasks to AI agents instead of writing every line manually. You can see it as more of an Agentic Development Environment (ADE) rather than a traditional Integrated Development Environment (IDE). The latter builds its features around a central text editor, while the former arranges everything around the AI agent itself. Here's how JetBrains describes it: Air was born from the ashes of Fleet, an experimental editor that the company quietly killed in December 2025 after realizing that competing directly with VS Code was a losing battle. The company repurposed Fleet's lightweight, modern architecture to build Air, transforming a basic code editor into a workspace for running multiple AI agents. When Air launched, it was only available for macOS. It wasn't until earlier this month that Linux users got a chance to play with the software. Now that Air is on Windows, you can do things like map out a complex feature in Plan mode and watch an AI write the implementation plan to a markdown file before writing any code. You can iterate on this plan, add references to specific classes or files, and choose whether to run the agent locally or inside an isolated Git worktree. Running agents in parallel means you can have Claude refactor a database schema in one branch while Codex writes tests in another, leaving you free to do other important things. You can even set up a pipeline where Claude writes the code, and Codex reviews it. At the moment, Air is free. If you have a JetBrains AI Pro or Ultimate subscription, you get full access to the built-in agents, though there's also the option to Bring Your Own Key (BYOK) to run APIs from Anthropic, OpenAI, or Google. If you're interested, here are the download links for both x64 and ARM64.
    • Depending how you’re wiring it internally, but try to put it inside conduit, that way in the future you can more easily replace cables, compared to running inside studs alone At least cat6a too
    • I bet Meta has lots of info on you anyway, gathered by other means. And Google, and Microsoft, and every other tech giant. If you use some form of modern electronic device, they own you already...
    • I'm using Windows 11 Pro 25H2 on "ancient" hardware, too: - Core i7 3770K - GTX 1050 2GB - 16GB DDR3 1333 MT/s It runs flawlessly, not a single issue. I also have it on other ancient setups, but I don't remember the exact specs right now (Intel 4th. generation).
