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 🚀

Software finally solving for colorblind users. Coworkers generally find out I’m colorblind the first time they put a color-coded spreadsheet or graph in front me. Right after that, we play the “what color is this?” game until I lose enough times to prove I’m colorblind. The WSJ report that tech designers are finally adopting signals beyond color and that sounds wonderful! | learn more
The secret history of the war on public drinking. I learned from this article that drinking in public was not banned anywhere until 1975. Now it’s banned practically everywhere. How and why did that happen? | learn more
Covid-19 superspreading events database. “Superspreading Events (SSEs) are events where multiple people —a minimum of 5, for example — get infected with the novel coronavirus.” Highlight: 220 people in Germany sick after, “4-hour-event. Live music, ritualized kissing.” This is a database of information about 1,100 such events, including event setting, location, indoor/outdoor, etc. | learn more
oh, chicago 🏆
Proposed Chicago ordinance will require landlords to provide air conditioning. Currently landlords are required to provide heating to a minimum temperature, but not cooling. Given many buildings were built before air conditioning was widely adopted, this sort of makes sense. Except that Chicago’s summer is unbearable without air conditioning. If the regulation makes sense for heating, it makes sense for cooling too. Regulators should beware of second-order effects, though, because the cheapest air conditioners also use the most energy. | learn more
tech, startups, internet ⚡
Venture capital patterns and mental models. This is basically cliff’s notes for venture capital. “Venture Patterns catalogs the best of what other startups and venture capitalists have figured out. Don’t reinvent the wheel. Since there are recurring patterns in how to build and run startups and funds, learn from what others have done and innovate where helpful.” | learn more
The best way to get PR for your new software launch. The team at Basecamp launched a new paid email service called this week. Like Gmail, it’s email service & email software bundled together with some new bells & whistles. The founders are now publicly feuding with Apple over the App Store’s 30% cut of revenue, generating loads of free publicity coinciding with the product launch. I tried Hey this week and it’s a nice product, though I don’t plan on switching any time soon. | learn more
better doing 🎯
When safety proves dangerous. Farnam Street discusses risk compensation, like driving faster because we strap on our seat belts. “Understanding how it affects our behavior can help us make the best possible decisions in an uncertain world.” | learn more
to your health ⚕
Using Covid-19 to renegotiate your antitrust settlement. Sutter Health, a California health system with 43% net profit margins over the past decade and $13 Billion in revenue last year, “was accused of using its market dominance in Northern California to illegally drive up prices.” They had agreed to a $575 million settlement six months ago but haven’t paid anything or made any changes yet. Now they want to unwind it because of financial hardship. | learn more
retail therapy 💸
Walmart and Shopify team up. Walmart’s had an online marketplace since 2009, though it’s always fallen short of Amazon’s in scale. Now they’re teaming up with Shopify to bring more sellers and more products to the platform. It’s also a reflection of (I think) philosophical differences that the tie-in is restricted - not just anybody can sell anything. “The deal will open Walmart’s Marketplace to Shopify’s small business sellers, with the goal of bringing 1,200 Shopify sellers to the marketplace this year.” | learn more
under the microscope 🔬
Robotic white blood cells crawl against the current to deliver drugs. “Rather than swimming through the blood like other micro-robots, the new ones move by rolling along the walls of blood vessels, much like white blood cells do. The direction of this movement can be controlled from outside the body by way of a magnetic field. When switched on, the metal-coated side pulls the spheres in that direction.” | learn more
big ideas 📚
Nuclear power for the moon. “Because resupply missions are challenging and sunlight doesn’t reach some parts of the Moon, NASA is betting that simple, lightweight nuclear reactors are the way to go.” I especially love this because when I was a kid, I thought it’d be cool to build our nuclear power plants in space and have them beam down energy safely to Earth. Unsurprisingly, I never quite worked out the details. | learn more

The crypto price-innovation cycle. From a16z: “Crypto cycles look chaotic, but over the long term they’ve generated steady growth of ideas, code, projects, and startups — the drivers of innovation.” | learn more
Seven years in prison for a $25 Million crypto scam. This was for the bogus ICO of Centra Tech which was promoted by Floyd Mayweather and DJ Khaled. The founder is now sentenced to 7 years in jail and a fine up to $250k. | learn more
