this thanksgiving... when your aunt/uncle complains of the complexity, per-country, high fee woes of operating a scaled worldwide business => now you can recommend they issue their own @stablecoin! - support global users - earn (and share!) yield - fast x-border transfers - apis


happy thanksgiving email from restaurants i went to that one time: automatic unsubscribe.


if you use @stripe, then @jrfarr wants to be your customer for bfcm [optional] give us feedback on bugs and feature requests!

Said this before and I strongly recommend this. Go to the library and read all the table of contents and intros to all the books in the topic and also the ones nearby on the shelves (they will be related). You will get a lot quickly even though you’ll only follow a bit fully.

This is actually good advice: you learn a lot from skimming the tables of contents of textbooks, understanding roughly what subtopics a topic consists of. If you then skim chapters here and there, you can get a rough sense of the big picture pretty quickly



every search bar will soon be powered by ai. (if you're a startup making a dead simple ai replacement for elastic search-y style use cases, i'd love to play with a demo + help in any way => [email protected])
