"Runctitiononal features"? "Medical fymblal"? "1 Tol Line storee"? This gets worse the longer you look at it. But it's got to be good, because it was published in Nature Scientific Reports last week: www.nature.com/articles/s41... h/t @asa.tsbalans.se

The move would save the state money in the short term to address Colorado’s budget crisis, but it could cost the pension as much as $180 million in the long run.

The Cinnamon Roll Project, part 2. Milk rather than water, no powdered milk. Shorter cut rolls, so less pan overflow. Less overnight rise, good spring in the oven.
Unbaked cinnamon rolls in two round pans, and some untied shoes. Baked cinnamon rolls now filling two pans. Shoes still untied.

Oh, uh, hi Xcode, I see you bouncing up and down there. Yeah, sorry, I don't need you right now, it's just an .md file. If you could just go back into your box for another six or eight months, that would be great.

This is scary but I'm taking The Film Maven off Substack and have transferred to Ghost. Not only does this give me complete ownership of my work, but also means I won't continue to lose money to Substack and Apple. I lay everything out for Subscribers here.

1/12 This Foreign Affairs piece by Dan Wang and Arthur Kroeber argues the US misunderstands why China succeeds in tech and manufacturing. The problem isn't that China "cheats" - it's built deep infrastructure enabling rapid innovation. I agree.

The latest in my history of home computers is live. Covers the era of Commodore, Atari and Jack Tramiel.

He was a brutal manager. But also an Auschwitz survivor, and that shaped him, and his legit drive to build a better world.

This warning from him hit home, right now.

every.to/the-crazy-on...
One day in 1982, Michael Tomczyk, who had led the project to develop the Commodore 64, found himself sitting in Jack Tramiel’s office. Tomcyzk had just returned from a trade show in Hanover, Germany. During the course of their conversation, Tomczyk mentioned how impressed he’d been with the Autobahn highway network on the way there. "I built that road," Tramiel told him matter-of-factly. “Jack went on to explain that during World War II as a teenager he had been selected to work on the road gangs,” Tomczyk remembered. “He said that it was one way to survive, because they had to feed the people that did that kind of hard labor, or they wouldn't work. ‘We built good roads,’ he said.” Tramiel had never hidden the horrors in his past. He was proud that he had helped build a better future through Commodore and Atari. However, the longer he lived, the more concerned he became that people would forget what that future had cost. And that which is forgotten can be repeated. "You know," Tramiel said once, "it's hard to believe it really happened. But it can happen again. In America. Americans like to make rules, and that scares me. If you have too many rules you get locked in a system. It's the system that says this one dies and that one doesn't, not the people. That's why I don't hate the German people. Individuals, yes. Rules, yes. But not all Germans.

Every baker should have a book like this floating around the kitchen. Full of recipes you would take to that high school potluck in 1995. My favorite carrot cake recipe. #baking
A yellow black plastic bound recipe book. The cover says choice hotels international with a drawing of a dinosaur combine with a suitcase. Underneath the dinosaur it says Choiceasaurus, Dino-mite recipes, followed by our commitment… Your choice 1993 A carrot cake recipe from the book, with notes from the baker. The recipe is one and 1/2 cups of flour, one cup of sugar, half a teaspoon of salt, 2/3 cup of salad oil, 1 teaspoon of soda, two eggs, 1 teaspoon of baking powder, one cup of shredded carrots, 1 teaspoon of cinnamon, 1 teaspoon of vanilla, half a cup of crushed pineapple with syrup. Mix until moistened about two minutes and pour in a 9 x 9” pan. This can be doubled for a larger cake. Bake at 350 degrees for 35 minutes.

I’m thrilled to see State in the spotlight for this achievement. Also surprised to see no mention of the U.S. Digital Service — a key partner in the approach that @bzcohen.bsky.social celebrates.
