lpviz – Interactive linear programming visualization in the browser
https://github.com/lpviz/lpviz Visualize linear programming solvers - Simplex, Interior Point, PDHG, and Central Path - in the browser.

Always happy to get feedback and feature requests, one thing that is coming soon is support for importing problems from e.g. JuMP or cvxpy.

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).
