I like fish, well-written code, all things food, tattoos, and the inevitable chaos brought about by poorly written code.

I wish the public could read the heartfelt goodbye emails I received from colleagues leaving the federal service this week. The brilliance, kindness, and dedication of the U.S. federal civil service is unmatched. Their departures are a loss for me, but also the entire American public. 💔

The wild thing about this is every single one of these 5000 contracts has made it through layers and layers of agency review and been deemed "mission critical" precisely because the secretary is insisting on reviewing them. There are probably 1000s of others that the agency just gave up on.
Per a source, Commerce Secretary Howard Lutnick, who has required that he approve all contracts over certain thresholds personally, has over 5000 review requests on his desk. Apparently he approves around 15/day.

Every year, thousands of invasive sea lampreys migrate up the rivers around the North American Great Lakes. Recently, Griffin & co discovered that, unlike other fish, sea lampreys stick to the deepest part of the river to stay safe and use less energy

my heart breaks from the stories pouring in from federal public servants. This is tragic, cruel, and represents an existential assault on everything that so many of us have worked on for so long. I am enraged, and if you care about basic human decency or sustainability in America you should be too.
