Thinkinh about how to fix science's code problem. What @coin_or has been thinking about for 20+ years regarding code in #orms. It's a difficult challenge.

Thanks to the help of @mkoeppe_math, CyLP now has a much improved build process, plus a Github Action that builds binary wheels bundling required libraries for all platforms using the amazing cibuildwheels 🚀. No need to separately install Cbc! github.com/coin-or/CyLP/rele…
Github now supports organization-wide Discussions! This supplants the few remaining mailing lists we had: the venerable coin-discuss and coin-announce, which served us well for 20+ years but have been showing their age. On to greener pastures! github.com/orgs/coin-or/disc…
We have an open position to join the COIN-OR Strategic Leadership Board as secretary. This is a great chance to build your connections with the shakers and movers in the OR/Analytics world. Contact us at [email protected] to become part of our board.
