Anyways, if you know someone who has ~2+ years of experience with Bayesian statistics in a production setting, is located in the U.S., Canada, or Latin America (U.S. Central or Eastern time strongly preferred), and wants to build a personalization engine for subscription apps with me, shoot me a DM.

It's ok to say "I don't know". Sometimes you need to "try everything" to be able to answer, even if it's a code assistant in plan mode www.youtube.com/watch?v=ULqy...

Coding agents like Claude Code feel like magic but they’re really a bunch of tools in a trenchcoat. This week I build a working coding agent in R, starting from just three tools. I’ll add some extra tools to make it safer and more efficient. tidydesign.substack.com/p/a-coding-a...

A coding agent is six functions in a trenchcoat
Coding agents like Claude Code, Cursor, and Codex have taken the software engineering field by storm. What makes them tick?
