waited so long to finish this book that my iPad somehow erased any evidence I’d ever started it? disconcerting. but at least this cafe is nice!

this obscenely large truck is parked behind me on the street. It’s so tall that my SUV backup cam can’t see the hood from a normal parking distance. this is the city! why would you possibly need this?

Made fancy European drinking chocolate last night and then used kid spoons (the rest were in the dishwasher) and stuck old marshmallows on top, like the gauche American I am

a big chunk of the book I'm currently writing is unpacking the crypto-anarchy piece of this. 🎯 "extreme vision of individual freedom and decentralized money" accompanied by "authoritarianism and criminality"
Highlighted text that reads: "It took an obscure technology, fueled by the Silicon Valley hype machine, mountains of dirty money and a massive gambling boom, to persuade millions of voters to embrace an extreme vision of individual freedom and decentralized money — and somehow overlook the authoritarianism and criminality that accompanied it all along."

Hmm, is it a good sign to see Gilded Age political cartoons go up in the neighborhood?

I shudder to think what my notes would look like if they were also full of hallucinated nonsense and anodyne summaries of books I've never looked at. yes I often forget entire months of research that I then have to stumble upon later but that is part of the fun?
two-pane meme of Daniel Craig as Benoit Blanc in Knives Out. In the first he's saying "It makes no damn sense." with a pained expression, and in the second he says "Compels me though," looking resigned to his fate as a chaos human investigating other chaos humans

great excuse to bring back one of my favorite @xkcd.com
xkcd cartoon (#1838) depicting stick figure 1 standing atop a heap holding a shovel. stick figure 2 asks: "This is your machine learning system?"
stick figure 1: "Yup! You pour the data into this big pile of linear algebra, then collect the answers on the other side."
stick figure 2: "What if the answers are wrong?"
stick figure 1: "Just stir the pile until they start looking right."

Lifehack culture has completely gone off any kind of rails it ever was on to begin with.

Literally what is the point? what epistemological function could this possibly serve

Happy five year birthday to this photo of the best billboard I’ve ever seen
A billboard with a photo of some trees with some sweet 90s-style word art in various colors: “Here are some quotes that you can tweet. 
When you find your purpose you stop searching
True success is a relationship with God. 
Text God and he will text you back. 
Prayer is how you text God. 
Hope means it’s never to [sic] late”

Buying a package of (low-quality!) vanilla beans was maybe the best $20 I ever spent. I haven’t bought extract in over eight years but cycle through one of these bottles every few months.
two small clear bottles with black caps on a quartz countertop. the left hand bottle is full of vanilla beans and brown liquid. The right hand bottle also has vanilla beans but the liquid is mostly clear.
