"You didn't protest correctly"

- Old centrist proverb

Tom Bombadil is a god from a pantheon unrelated to Eru Iluvatar that Manwë doesn't want you to know about

Very proud of, and sad for, our friends at @thecarpentries for turning down a $1.5M #NSF grant rather than abandon their values. The (illegal) demands that they abandon DEI work were fundamentally at odds with their mission, and they made a hard and principled choice.

Announcing Withdrawal of NSF Pathways to Enable Open-Source Ecosystems Proposal

In September 2024, The Carpentries submitted a proposal to the U.S. National Science Foundation (NSF) Pathways to Enable Open-Source Ecosystems (POSE) Program. This project would position The Carpentries as a leading open source ecosystem and further solidify our independence as a 501(c)(3) nonprofit organisation. Developing a proposal of this magnitude (1.5 million USD) involved a significant amount of preparation, from conceptualisation of the idea to navigating the complex submission process. It was the first time The Carpentries did it on our own, with our Associate Director, Erin Becker, leading as principal investigator.

love to see it

We talk a lot about #sea level rise due to #warming and ice melt. That it's not just based on models. We have a robust #geological record of ice melt events to talk about this with relative confidence*.
