What it does
FacetLab is a free, open-source WebGL learning simulator from 4Cs.co.za. Inspect a rough diamond crystal, reveal inclusions, plan the proportions, polish the facets of a brilliant cut, and generate a finished 4Cs scorecard (cut, colour, clarity, carat). It runs entirely in your browser. Educational only: no signup, no pricing, no appraisal. Source open on GitHub.

- H6Homebrew 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!
