We received 125 applications for the energy policy analyst role at Gridworks. It's like sorting through an embarrassment of riches. There are so many qualified applicants, refugees from fed agencies. It's sad we can only hire one. Reach out if you're hiring; happy to forward candidates along to you.

I think it sucks that as far as I know the only way to get off a starter pack you don’t want to be on here is to block its creator but here we are. If anyone knows a more graceful way to exit a starter pack please lmk.

Gladys Mae West obituary: mathematician who pioneered GPS technology She made key contributions to US cold-war science despite facing huge barriers as a Black woman.

No joke: I got angry hate mail today for writing an obituary of a Black woman scientist—because the person felt she did didn’t deserve the recognition.

Which just makes me want to share it again: www.nature.com/articles/d41...

Getting off US tech: a guide I’m in the process of dropping US tech services. Here’s how I did it, and options you should consider.

Silicon Valley’s alliance with Donald Trump was a mask off moment and showed the world we can’t depend on US tech companies.

For the past few months, I’ve been trying to get off US tech and I put together a guide so you find alternatives too. I hope you find it helpful!
