CoordConversions NPM Module for Map Coordinate ConversionsOct 2025 · github.com · ▲8
I have been working on a project that has multiple repos, all of which have to convert between multiple map coordinate types, so I made an NPM module that allows you to parse and convert between Decimal Degrees, Degrees-Minutes, and Degrees-Minutes-Seconds coordinate types. Niche? Yes. Useful? Also yes (I hope)!

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!
