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 sixth year!

my story 🚀

Pastry breakfast date with Daphne before school. 🥐☕
  1. It’s nice to be home. After a summer spent largely on-the-move, it’s great to have spent the week re-settling into our Austin home. I am excited to get back to many of the healthy lifestyle choices I’ve been lax on: exercise, home-cooked meals, and (hopefully) meditation.
  2. Austin gets really hot. Of course, this is obvious to everyone, right? But until this week I hadn’t ever been here in the summer. While we were away our indoor temperature peaked at 97 degrees. Since our local utility sends a weekly report of electric usage, I now know it costs an incremental $5-7 per day to cool our home.
fun facts 🙌
The 100 Prisoners Riddle feels completely impossible even once you know the answer. A fun video explanation. | learn more
Bird–building collisions in the United States. “We reviewed the published literature and acquired unpublished datasets to systematically quantify bird–building collision mortality and species-specific vulnerability. Based on 23 studies, we estimate that between 365 and 988 million birds (median = 599 million) are killed annually by building collisions in the U.S., with roughly 56% of mortality at low-rises, 44% at residences, and <1% at high-rises.” | learn more
The Microsoft Excel world championship. “Over the weekend, ESPN broadcast a replay of a recent esports event that saw the world’s most advanced Microsoft Excel users go head-to-head in a knockout tournament.” I watched a bit of this and frankly was a little lost because I didn’t understand the spreadsheet they were working on. But I could see myself enjoying this another time. | learn more
oh, austin 🤠
Things old Austin hates that are just part of the city to newcomers. “With expansive population growth, new businesses steadily flowing in, celebrities snapping up local property and constant new development, Austin is making its way through some growing pains. Here are some of the parts of the city longtime Austinites gripe about and newcomers don’t notice.” | learn more
The difference between xeriscape and zeroscape. I hadn’t heard of this until I moved to Texas. Keeping plants (and grass) alive down here can be hard, so often landscaping is designed to require no water. When I finally saw the word ‘xeriscape’ written out, I thought it was a typo. Nope. I learned something new that day. | learn more
tech, startups, internet ⚡
Seed stage founders undervalue angels with marketing & comms expertise. VC investor Hunter Walk of Homebrew thinks that founders should make an effort to bring these angel investors with this background into their seed rounds. Here he makes the case for why. | learn more
better doing 🎯
Synchronization can be distracting. “We are primed to pay attention to things that happen in a thunderclap. But the events that change our culture often happen over time, distributed across parts of the population too small to notice.” | learn more
to your health ⚕
How will Amazon approach U.S. primary care? Musings by two MBA professors who specialize in the healthcare industry: Robert S. Huckman and Bradley Staats. “Amazon has a playbook for reinventing businesses that it enters. It includes simplifying processes, experimenting to determine which new approaches work best, and continuously recombining its existing assets to come up with a better way to do things.” | learn more
under the microscope 🔬
The brain enters ‘low-power mode’ to blunt senses when you eat too little. “A significant implication of the new findings is that much of what we know about how brains and neurons work may have been learned from brains that researchers unwittingly put into low-power mode. It is extremely common to restrict the amount of food available to mice and other experimental animals for weeks before and during neuroscience studies to motivate them to perform tasks in return for a food reward.” | learn more
Pig organs partially revived in dead animals. “Researchers have restored1 circulation and cellular activity in the vital organs of pigs, such as the heart and brain, one hour after the animals died. The research challenges the idea that cardiac death — which occurs when blood circulation and oxygenation stops — is irreversible, and raises ethical questions about the definition of death.” | learn more
First trial to prove a diet supplement can prevent hereditary cancer. “A trial in people with high hereditary risk of a wide range of cancers has shown a major preventive effect from resistant starch, found in a range of foods such as oats and slightly green bananas.” | learn more
big ideas 📚
We’re going to need a lot of solar panels. This will really expand your mind. Casey Handmer makes the case that with the solar costs declining 30% with every doubling of production, an average doubling time of 3 years, and a little more time, we’ll soon see solar energy making it cost-competitive to generate natural gas from atmospheric CO2. The net impact is no more pulling carbon out of the ground to release it into our atmosphere! | learn more
on the blockchain ⛓
MakerDAO may execute ‘Emergency Shutdown’ if sanctions hit DAI. “Maker is making contingency plans to execute an emergency shutdown should core contracts underpinning DAI, its stablecoin, be sanctioned by Washington, according to posts from MakerDAO founder, Rune Christensen, in the project’s Discord channels. “If we get nuked by the U.S. government, we simply die,” Christensen warned.” | learn more
Tornado Cash hijinx. This blockchain service is used to launder cryptocurrency, and the US government recently banned it. Interacting with it can get your accounts frozen. So someone decided to have some fun: “Max chaos — someone is sending TC’d ETH to big doxxed wallets like Shaq, Beeple, Randi Zuckerberg, Ben Horowitz, Brian Armstrong, etc” | learn more
