P.S. You Should Know...
👋 Welcome back to P.S. You Should Know… probably the best newsletter published on Sundays between 6-7am CST, and definitely the best one published by me. Now in its fourth year!

my story 🚀
🎬 I’m afraid of documentaries. In my latest post, I explain why.
🤠 Every year I threaten to leave Chicago for the winter because of the weather. This year, I’m thrilled to say we’re finally making it happen. The Sokolovsky family is heading to Austin for the winter! In preparation for my stint as a Texan, I’m building up my library of fun Southern lingo. I’ve already adopted y'all, which is far superior to the yankee you guys. Someone recently taught me, “all hat, no cattle.” Please help by sending over your favorite southern, rural or small town expressions.
💼 Lots of great companies in my network are hiring. If you or someone you know is in job search mode, you can see an updated list of jobs in my network here.
someone else's words 💬
fun facts 🙌
Incredible engineering to “grow” islands and coastlines. Skylar Tibbits is the founder of the Self-Assembly Lab at MIT. His team’s work is incredible, and his TED talk is the coolest I’ve seen in a long time.

tech, startups, internet ⚡
Business model meta-models. The Diff by Byrne Hobart is quickly becoming one of my favorite newsletters. “[T]here are many ways to frame business models. Every one of them asks how a business reverses economic entropy and creates more value than it consumes… None of the models are wrong, but all of them are limited. And when one model stops working, it’s important to switch to the next.” | learn more

The observer effect: seeing is changing. “The act of looking at something changes it – an effect that holds true for people, animals, even atoms. Here’s how the observer effect distorts our world and how we can get a more accurate picture.” I love how Farnam Street’s Shane Parrish offers examples of the mental model’s usefulness in multiple fields. | learn more

Mike Tyson is building a 418-acre weed-themed resort. “The former heavyweight champ, famous for delivering a knockout punch, has been selling cannabis products since 2016 through his Tyson Holistic label that are as potent as one of his uppercuts.” | learn more
Nike continues closing wholesale accounts. The dynamic between brands and retailers is in flux. For decades, most brands needed retailers to reach consumers. For some time, they just preferred the convenience of selling in bulk to few customers. Now many of them have built enough direct-to-consumer infrastructure to own the full retail channel. “Nike is closing nine of its wholesale accounts as it aims to prioritize its direct-to-consumer (DTC) channels and continue its transformation into a digital-first company.” | learn more
under the microscope 🔬
“Cold Tube” cooling system uses half the energy of an air conditioner. “A team of scientists has been developing an alternative to air conditioning called the Cold Tube, which works by absorbing body heat emitted from a person and uses around half the energy of traditional systems as a result.” | learn more

Bitcoin miner scoring 700% profits selling energy to grid. The miner is in a part of Texas that’s flush with wind power.
