fun facts 🙌
Painting yourself into a corner. I used this metaphor and a friend noted that this only makes sense if you’re painting the floor. The Ngram chart implies people started doing this in the early 20th century. | learn more

oh, chicago 🏆
More bad outcomes of dropped charges. It’s too easy to read into this as an abdication of duty by prosecutors. Maybe they should get more benefit of the doubt? Maybe not. “Prosecutors wouldn’t charge him with shooting 2 women, so CPD overrode their decision. Prosecutors drop all charges anyway. Now, he’s charged with attacking another woman.” | learn more
tech, startups, internet ⚡
Insuretech Act 1: the curtain falls on the hare. “With most of the public insuretechs now down somewhere in the neighborhood of 90%, it’s pretty clear that the hype cycle is over and there’s no need to pile on anymore.” | learn more
Quant comes to venture capital. “Advanced techniques are applied to study patterns of growth, failure, value evolution, and performance.” This form of analysis has proven valuable across multiple classes of investments. The pace of VC deals nowadays might provide enough data to apply the approach to private markets. | learn more
Minsky moments in venture capital. “Hyman Minsky was a 20th-century economist whose ‘financial instability hypothesis’ is probably the best-known explanation for the boom and bust cycles that characterize public financial markets. … We’re currently in the midst of an unprecedented boom in private market activity. Tech entrepreneurship, angel investing, and venture capital have never been so widespread. Can Minsky cycles happen in this realm as well?” | learn more

The myth of exponential hypergrowth. Jason Cohen doesn’t think exponential growth is a thing. He offers an alternative model that better fits a variety of growth data from hypergrowth products and companies. Lots of great charts to make a strong semantic point. | learn more
How to simplify your life — and get rid of your stuff. This statistic was a strong opener to the article. “We’re filling our lives with so much junk that the U.S. now has more self-storage facilities than McDonald’s, Wendy’s, Burger Kings, Starbucks and Walmarts combined. That’s around 50,000 storage complexes.” | learn more
The best friends can do nothing for you. “Think for a minute about your friendships. Some friends you would text with any silly thought; others you only call a couple of times a year. Some are people you look up to; others you like, but do not especially admire. You fit into these categories for others as well—maybe you are helpful to one person, and a confidant to another. We get different things out of different relationships, which is all well and good.” | learn more
to your health ⚕
NutriSense cofounder interviewed on health tech. “People, People, People. They are what matters. You can start something incredible with the wrong people and fail or start an average idea with the right people and win.” | learn more
under the microscope 🔬
The Pentagon is working on an algorithm to detect Covid early. Preliminary results of the study, “show the algorithm’s projected accuracy is about 82 percent with a false positive rate of 11 percent over a 14-day period.” This is one of a few groups working on early detection with wearables. What exciting capabilities for humankind! | learn more
Soundwave microchip to grow new bone cells. This is like science fiction. Lob the right sound frequency at stem cells and they turn to bone. “We can use the sound waves to apply just the right amount of pressure in the right places to the stem cells, to trigger the change process,” said researcher Leslie Yeo. | learn more
thoughts of food 🍔
Reading up on bagels. “The result is a dense, chewy, doughy interior with a browned and sometimes crisp exterior.” | learn more
teaching the kids 👩‍🏫
College: how to make the most of it. A ton of good advice for students in here. “Signaling is the only good reason to go. Still, once you’re on campus, you might as well make the most of it. I’ve been in college non-stop for the last 33 years, and I’ve been paying close attention. Here is how I advise you to get good value for all the time and money you’re spending.” | learn more
