  • Random Code Inspiration Volume 2
    Image-shrinker is a simple, easy to use open source tool for shrinking images. Under the hood it uses pngquant, mozjpg, SVGO, and gifsicle. You can also install these tools individually if you need to compress some images. I often use pngquantafter exporting PNGs for web projects from Figma or similar tools. I literally run it like this:. - Source: dev.to / 8 months ago
  • keeping collection size down (for ankiweb) when needing lots of image cards/notes
    Searching more I found https://pngquant.org/ which I could add to my bulk workflow to make most png's approach the jpeg size. Source: 12 months ago
  • screen capture/snapshot utility with image optimization support/configurability
    But this did prompt me to do some searching, and I see https://pngquant.org/ which seems to achieve jpeg like size reduction while maintaining the file as a png. One difference they note is that this method will typically preserve sharp edges better than jpeg (which is probably a strong plus for my type of use case). Source: 12 months ago
  • Exported png image with color-to-alpha edit is huge
    Pngquant is also great for shaving filesizes down, but unlike oxipng, it's explicitly lossy. It'll reduce colors and even dither, but it will try to keep an image visually similar. Https://pngquant.org/. Source: over 1 year 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 / 1 day 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
