What I'm up to - June 2025
June 11, 2025
Here's my monthly newsletter about what I'm up to, which I send in place of social media. What I did in last month• On Contraption Company, I published An app of one's own about building a personal app for life automation, and How I built a chatbot with my dog about vibe coding. • Spent Memorial Day weekend in LA.

A topic that stuck with me from the talk: taste-skill gaps. • Been busy working on Chroma, and we published a blog about our usage-based billing systems. Things to share• Articles: Europe Built Trains, America Built Highways and Regret.

I saw many Reviver e-ink license plates in LA, though I still don't understand their purpose Plans for the next month• I'm working on open sourcing Postcard.
