stuff i've enjoyed

Jul 09, 2025

Friends,

Moontower regular publishing resumes next week…but I did a lot of reading and listening on the way to and from Italy/Malta and a fraction of it is lingering with me so I’ll boost all the goodness here over the next couple days.

Today, you get the best of the podcasts I jammed to.

🎙️Podcasts

Rick Rubin’s Tetragrammaton Podcast:

Conversations with Tyler:

Chris Arnade on Walking Cities

Intentional Investor with Matt Zeigler:

Andrew Mack (I’ve had the privilege of chatting with Andrew several times and even writing the foreword to the option book he co-authored with Euan Sinclair, but I did not know his wild history. This dude is the definition of antifragile. Plus this epsiode was Zeigler’s best guest intro ever and that’s saying a lot.)

Extras

SEBI

Agustin Lebron (entrepreneur, author of Laws of Trading, and former Jane Street trader) kicked the week off with thoughts on the SEBI allegations of Jane Street’s manipulations in India’s options market.

I read the allegations over the weekend and having started my own career in index options had a few thoughts. They veered a bit more into the evergreen education direction and ended up going viral (for me at least — certainly not outrage-farming numbers).
