Color Vision Labs

What it does

Free, science-based color vision tests that run in your browser: a 2-minute adaptive screening (type + severity), Ishihara, D-15, FM-100 and more — plates are generated fresh every run, so answers can't be memorized. New: a live camera filter (daltonization) that re-maps the colors you confuse into ones you can tell apart — processed entirely on your device. No sign-up, nothing uploaded, honest about what a screen can and cannot measure.

  Homebrew 6.0.0▲1,481

  Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!
