  • Modos Paper Monitor Pre-Launch on Crowd Supply
    Give Flux a try. https://justgetflux.com/ It did it before night mode and does it far better. ;). - Source: Hacker News / 15 days ago
  • Tools that keep me productive
    For those evenings where I'm in front of the computer, f.lux is a must. Like some wise person said, "Be kind to your eyeballs". macOS's Nightshift kind of works, but f.lux destroys it. - Source: dev.to / about 1 month ago
  • Ultra Librarian Joins Flux to Take the Hard Out of Hardware
    Having never heard of Ultra Librarian, I thought this was somehow related to https://justgetflux.com/ and that they'd made a switch from doing color changing to hardware. - Source: Hacker News / 3 months ago
  • Is it just me who dislikes the winter update with the change of colors?
    Reshade might help with the color tones. I normally use f.lux for Windows, but I don't know how much it might help. Could be worth trying, though. Source: 6 months ago
  • Create a shortcut for even lower phone brightness
    This is good advice, but I prefer something that automatically dims and reduces blue light for me. That qay I don't have ro remember. f.lux on Windows and Mac, and Twilight on Android, are what work for me. https://justgetflux.com/ https://play.google.com/store/apps/details?id=com.urbandroid.... - Source: Hacker News / 7 months ago
