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 fifth year!

my story 🚀
  1. Towing a trailer? We’re planning our move back down to Texas at the end of this month. Once I saw the quotes from moving companies, I started to wonder if I might successfully tow a trailer behind my truck. I watched a youtube video, so I’m probably at the peak of my Dunning-Kruger effect. If you have experiencing towing trailers (think: U-Haul 6x12 cargo trailers), I would love to hear from you before I do anything dumb.
  2. The great debate over thank you notes. Last week I commented that thank you notes are one of the simple steps that can set candidates apart in a recruiting process. One friend strongly disagreed with the practice: “The main issue for me is that we do 6-8 interviews per candidate (who gets hired). Are the supposed to send a thank you for each one? How do they get the emails? They can’t copy and paste because that would be uncovered (and tacky), so they draft something tailored for each person. But, what if they didn’t bond with one person. Then it is an impersonal email and makes them look like they don’t care…” I think this adds a very valuable perspective and it makes me want to sharpen my point. I don’t believe thank you notes should be required, nor should anyone be disqualified for not sending one. I also don’t think they are helpful after every single interview. I think they offer a potential benefit to candidates by reminding the interviewer of their existence and creating an easy way to continue a conversation.
fun facts 🙌
How I experience the web today. Painfully accurate. | learn more
The disastrous voyage of Satoshi, the world’s first cryptocurrency cruise ship. “Last year, three cryptocurrency enthusiasts bought a cruise ship. They named it the Satoshi, and dreamed of starting a floating libertarian utopia. It didn’t work out.” | learn more
What is Wikiality? The term was coined by Stephen Colbert in 2016. It’s, “a version of facts which is agreed to be true, but which may not coincide with objective reality.” | learn more
oh, chicago 🏆
More kids shot in Chicago than have died of COVID-19 across US this year. This is incredibly sad, although the framing is annoyingly politicized. Seemingly all of my conversations about Chicago this year have turned to talk of violence. | learn more
A secret society of Chicago bakers. “The Bakers Dozen was founded in the 1930s. Its members — beloved bakery owners — meet in secret once per month to sample each other’s goods, catch up and help keep their businesses alive.” | learn more
tech, startups, internet ⚡
How synthetic biology enables us to create new living things. “The real limit of synthetic biology technologies over the next decade may be our collective imagination.” | learn more
better doing 🎯
Machine learning predictions of panic selling. “Despite standard investment advice to the contrary, individuals often engage in panic selling, liquidating significant portions of their risky assets in response to large losses.” | learn more
Minimum viable product manager. “That intersection is what I call the Minimum Viable Product Manager (MVPM), and it defines a set of skills or knowledge that are useful to be an effective generalist product manager, one who can work on almost any problem.” | learn more
to your health ⚕
Experiments on a $50 DIY air purifier you can make in 30 seconds. “If you’re in a hurry, this post says that if you strap two HEPA filters to a box fan, it will clear the air of basically all the particles we can measure, and it will do it faster than a commercial filter that costs twice as much.” | learn more
retail therapy 💸
What do you do with a billion grams of surplus weed? “We have more pot in [Canada] than we can possibly sell. Producers today are sitting on a massive, and predictable, oversupply that is slowly becoming worthless—and that’s going to cost a lot of companies a lot of money.” | learn more
under the microscope 🔬
To learn more quickly, brain cells break their DNA. “New work shows that neurons and other brain cells use DNA double-strand breaks, often associated with cancer, neurodegeneration and aging, to quickly express genes related to learning and memory.” | learn more
Dietary fructose expands the gut’s surface and promotes nutrient absorption. “Feeding mice high-fructose corn syrup, a widely used sweetener in human diets, has been found to drive an increase in the surface area of the gut that is associated with enhanced absorption of dietary nutrients and weight gain.” | learn more
thoughts of food 🍔
There’s a tortilla shortage in Chicago. “Across Chicago and in the surrounding suburbs, folks have found empty shelves instead of El Milagro tortillas. It’s the second time since the pandemic began that the tortilla producer has faced a shortage, but it’s unclear what is causing it.” | learn more
big ideas 📚
How can we make air conditioners 33% more efficient? “Now a market disrupting technology has been launched that increases compression speed by 38% while using 33% less electricity. Multiply that by billions of units and you get a pretty helpful contribution to reducing greenhouse gas emissions!” | learn more
How do we build more exceptional institutions? “Since institutions depend especially on the most skilled people, institutional health is largely determined by what happens to these people. Where they are plentiful and coordinated, institutions will flourish. Where they are scarce or fractured, institutions will decline.” | learn more
on the blockchain ⛓
Theory: Biden administration leaving door open to adopt Bitcoin. “Why on earth would the Biden White House be pushing proof-of-work at the expense of proof-of-stake, when environmentalism is a hallmark of the Administration and public perception is (albeit incorrectly) that PoW is killing the environment?!?” | learn more
Regulators investigate crypto-exchange developer Uniswap Labs. This is a fascinating story to watch because the company makes a decentralized exchange. That means the company could disappear tomorrow, but the exchange can persist because it’s open source and lives on the blockchain. You can’t put that toothpaste back in the tube. | learn more
