  • 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 / 2 days 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 / 2 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: 5 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 / 6 months ago
  • Blue-light glasses may not reduce eyestrain from screens, study says
    > I can't put nightmode in Windows too close to 100 percent (i put it between 50-65) because then the contrast is just too bad. I hate windows night mode. As soon as you go above "slight" (can't remember the numbers, I'm not a frequent windows user and don't have one handy to check) it gets a sickly yellow taint. Last I checked (2-3 years ago) macos's wasn't great either, although somewhat serviceable. You may... - Source: Hacker News / 9 months ago

  • The fastest tool for measuring anything on your screen
    ShareX (https://getsharex.com/) doesn't have quite this nice UX but it's free. I often use it alongside browser dev tools. Here's a screenshot of me measuring this comment box https://i.imgur.com/yoTHbzq.png. - Source: Hacker News / 2 months ago

    ShareX will run on that machine no problem. Open-source & free. Https://i.imgur.com/KQAoDin.jpg. Source: 5 months ago
  • 'Screen Apnea'
    ShareX [1] is my other "must install" app. I never would have guessed how much my branch of engineering consists of "take a screenshot and draw lines, arrows and circles on it." Being able to customize my workflow to do all of that is really great. [1] https://getsharex.com/. - Source: Hacker News / 9 months ago
