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 🚀
📚🔄 Like many families, our library of children’s books grows non-stop. We collect books we might never read again. This weekend we held (huge thanks to Mr. Dave Music for the space!) a toddler book swap to help everyone take home some fresh reading material and reinforce the value of books and reading. I also felt it was a great experiential lesson on how trade creates value for all. I’m not sure our 2-year-old fully grasped that lesson. 😂
🙏 Thank you to everyone who reached out last week to share feedback about the newsletter and how you think about spending your time. I’ve confirmed there’s no ‘easy button’ to solve time allocation. However, there is consensus: time spent optimizing how we spend time is a great investment. Keep the notes coming my way, everyone!

fun facts 🙌
Just monkeying around. 🙊
Just monkeying around. 🙊
Marauding monkeys take over government office block. “Troops of monkeys have raided the offices of India’s top cabinet ministers and taken over, leaving ministers too scared to make eye-contact with the animals.” | learn more
Cargo cults – imitation without understanding. During World War II, the Japanese and Allies took turns occupying the islands of Melanesia. Both sides flew in loads of cargo–supplies and military equipment. After the war, the supplies stopped coming but charismatic cult leaders took advantage of the deep desire for more. “The islanders carved headphones from wood and wore them while sitting in fabricated control towers. They waved the landing signals while standing on the runways. They lit signal fires and torches to light up runways and lighthouses.” | learn more
oh, chicago 🏆
Former Governor Rod Blagojevich has now filmed 219 Cameos. That’s estimated at $15-25k of income for him in the past week (before Cameo’s cut). Cameo’s CEO Steven Galanis: “The former governor mirrors a lot of what makes other people successful on Cameo. He’s good in front of the camera, he’s got a big personality. He was a reality TV star. Our best vertical is reality TV stars.” | learn more
Should Chicago cops have to pay for their own misconduct insurance? “Misconduct settlements have cost the city $800 million since 2004, a new report found. Should taxpayers be on the hook?” I bet most of us don’t even realize who is funding all the settlements. | learn more
Chicago’s pitch for Amazon HQ2 revealed. “Newly unveiled secret documents reveal how Chicago officials tried to accentuate the positive—and spin the negative—in their bid to woo the e-commerce giant.” | learn more
tech, startups, internet ⚡
Hard startups. Sam Altman writes, “The most counterintuitive secret about startups is that it’s often easier to succeed with a hard startup than an easy one.” | learn more
1 startup, 2 people, 28 software tools. “At Across, we wanted to see how many other technology companies and service providers we use on a regular basis. The answer was way more than we thought.” | learn more
Levels of software developer seniority. Are you curious what distinguishes a junior, mid-level and senior developer? This is one guy’s detailed analysis. | learn more

The cobra effect – unintended consequences. Once upon a time in Delhi, the governor decided there were too may cobras. So, he set a cash bounty on cobra skins. Entrepreneurial citizens began farming cobras to earn cash. The government got wise and canceled the program. The farmed cobras were no longer valuable, so the farmers released them rather than deal with them. Delhi ended up with way more cobras than they started with. | learn more
to your health ⚕
Are hand sanitizers actually harmful? With the latest concerns about virus spread, people are pumping hand sanitizer at an alarming rate. Here’s an article from Rush University Medical Center highlighting their view. Hand sanitizer has its place, but stick to soap & water whenever possible. | learn more
retail therapy 💸
H&M opening up its supply chain to rivals. They’ve been focusing on sustainability in their supply chain for a while, and are making an Amazon-esque move by opening it up as a service to other brands through a B2B service called Treadler. | learn more
Trunk Club closing all retail stores. Nordstrom acquired the business in 2014, wrote down its value significantly in 2016, and now is shutting down all their retail stores. The company, “has not decided on the fate of the Trunk Club branding.” Personally, I always enjoyed the in-store experience hanging out in their cool Chicago office, drinking free whiskey, and having a mini fashion show. | learn more
under the microscope 🔬
Self-healing potassium batteries. The question of what’s next after Lithium is a big one for the battery business. “Potassium metal batteries could offer a cheap, long-life alternative to lithium cells with similar energy density, but thus far they’ve been held back by dendrite formation issues. Now, American scientists say the issue is solved and the path clear.” | learn more
Editing genes with CRISPR inside a patient for the first time. In the past they’ve taken cells out, edited them in a lab, then put them back. This time, researchers engineered a virus to make the edits directly inside the patient to fix blindness. “They hope to know within weeks whether the approach is working and, if so, to know within two or three months how much vision will be restored.” | learn more
thoughts of food 🍔
How ultra-processed food took over. From this article, I learned about the Nova system of classification grouping foods by the level of processing. Group 4 is ultra-processed, alleged to be the major cause of obesity. Researcher Kevin Hall thought this was “nonsense” and the prior literature was all based on correlations, so he performed a randomized controlled study. Surprise! “Hall’s study provided evidence that an ultra-processed diet … really does cause over-eating and weight gain, regardless of the sugar content.” | learn more
Your genes could determine your favorite foods. Don’t take this one too seriously, but it is fun to think about nature vs nurture when it comes to food preferences. “Whether you’re inclined to choose coffee or green tea for your morning boost could be determined by your genes, a recent study found.” | learn more
big ideas 📚
Protein from outer space discovered for the first time. Slow down–this does not mean aliens exist. However, it does signal the building blocks of Earth life may have come from space. “Named hemolithin, the new protein contains iron and lithium and may play an important role in seeding life on habitable planets like Earth.” | learn more
