This is my monthly newsletter about what I'm up to, which I send in place of social media. What I did in October• Switched my daily driver Aeropress coffee recipe to this one by Jonathan Gagné. It produces delicious results. (His book Physics of Filter Coffee is excellent.) • Witnessed the aftermath of a bike crash, did some activism, and got featured in an article on Curbed. • Booklet, the modern email software I make, as a bunch of new features.  • Postcard, the personal website software I make, continues to grow as people leave the site formerly known as Twitter. • Made some light updates to the Contraption Company website.  Things to share• Articles: How Linear builds products. "What I tell employees about negative press." How Not To Sort By Average Rating. • Music: nadie sabe lo que va a pasar mañana • Podcasts: Charlie Munger on Acquired.  • Apps: Cursor, an AI-first code editor, has replaced VSCode as my daily development tool. Dutch Cycling Lifestyle  is a fun use of AI. • Trend: While chat is the best-known product from OpenAI, the Embeddings feature is powerful and being incorporated into many products in ways that are not obviously "AI."  • Videos: Magnus Midtbø did some videos with Norwegian military that gave a documentary-like glimpse into their lives.  • Coffees I'm drinking: Tim Wendelboe Caballero Geisha. Plans for November• Continuing to build Booklet features. • Spending a couple of weeks in Europe for a mix of work and fun.  • Working on essays for Contraption Company.
