Solution of colour banding on macOS

macOS may show colour banding on an external display. To solve the issue, we need to follow the steps:

  1. Download the ZIP package of patch-edid.rb and uncompress it
  2. Type in ruby in Terminal and drag patch-edid.rb so it will look like ruby /<path>/patch-edid.rb, and then press the return key
  3. You will find the folder DisplayVendorID-xxxx in the /Users/<your account>/ folder
  4. Copy the folder to /Library/Displays/Contents/Resources/Overrides/, and you should create the folders by yourself following the same structure first
  5. Restart your computer

This solution works for recent macOS versions including Big Sur (version 11) and does not require SIP or any security function disabled.

Simple image formats comparison and optimisation

There have been many tests of image formats earlier before, but this time DSSIM was introduced for the more objective and more scientific comparison between lossy formats including JPEG, WebP and AVIF. Optimisation for 🔞Reconquest at Night was also introduced for reducing colour banding and adding a tremendous shallow depth of field.

More AVIF and WebP lossy tests

Here we have more lossy tests of AVIF and WebP comparing to JPEG or PNG, but with the much smaller resolution and very close file size for testing the real-life usages. By using the <picture> tag, the priority is AVIF, WebP, and JPEG/PNG so all browsers can display.

Breasts volume and weight formula

  • Underwire (US inch) = digits + (alphabet – 2) * 2
  • Diameter (US inch) = (underwire – 7) / 6
  • Diameter (EU metric cm) = [digits + (alphabet * 4) – 12] / 6
  • Volume (cm^3) = (diameter cm)^3 * Pi / 12
  • Weight (kg, one breast) = volume * 0.0009

Colour banding of WebP & AVIF

WebP has been promoted as the next-generation image format (for ten years!), and then its powerful competitor AVIF comes. Do they work as excellent as people’s expectations? Unfortunately, colour banding happens on both of the new image formats.
