The Python Software Foundation was recommended for a $1.5M grant from the National Science Foundation. The terms of the award said PSF could not work on DEI, whether or not the grant funding was used for it.
PSF therefore declined the funding.

We live in a fundamentally different atmosphere/ocean system thanks to fossil fuel-caused climate change. It’s time to name it explicitly and call out the actors that helped to make this storm incredibly dangerous.
UCS climate scientist @marc-alessi.bsky.social says: “The role climate change has played in making Hurricane Melissa incredibly dangerous is undeniable.”

The sidewalk in front of my house, I’ve lined with rocks from all over the world, from two billion years ago to the present, from all types of geologic environments. I wonder how many people pass by and never know they are walking back in time. LOL

i got pushed by docs into thinking my chronic migraines were just headaches from stress for five years - they were actually the primary manifestation of a tumor in my head. it took me a full year and half of fighting for myself to actually get the treatment i needed. it instantly cured me.
And so I anchored — I anchored on the first diagnosis I received. Even though that diagnosis was wrong. I'm sharing this experience not for sympathy or attention, but in the hope that it may be a useful cautionary tale. Do not make my mistake.

A lot of comments on Mars rovers or Moon landings, but it's important to remember that the planet NASA studies most is Earth. This is less about cutting flashy things like moonwalks and more about keeping communities in the dark on climate, weather, agriculture, pollution, natural hazards, and more.

NASA's Jet Propulsion Laboratory to lay off about 550 workers
NASA's Jet Propulsion Laboratory said on Monday it will cut nearly 550 jobs as part of a restructuring, not related to the current U.S. government shutdown.

For the first time ever, I have 2 textbooks: one for office, one for home. I keep my precious annotated & signed version at home. Thought it was nerdy to get the author’s autograph but a prof told me that students lined up for the same at a seminar once 😂
