tech, startups, internet ⚡
How an infant formula startup recovered from an FDA recall. A bit of publicity almost killed this startup, Bobbie, by drawing the attention of regulators to their pilot. This is the story of how they turned the situation around and capitalized on the moment. A couple years since this article was written, they have revenues over $100 million and more than 100 employees. ~ learn more
GPT-4 is getting worse over time, not better. This mirrors my (very limited) personal experience. “At least one study shows how the June version of GPT-4 is objectively worse than the version released in March on a few tasks.” ~ learn more

Excellence is a habit, but so is failure. “We often hear that making small incremental improvements every day can lead to great things. … But there’s another side to this story that we don’t discuss as often: how incremental neglect and small missteps can accumulate and lead to negative outcomes.” ~ learn more
You suck at Excel, with Joel Spolsky. This private presentation to an audience of engineers is now available on Youtube and its great. Joel was a program manager on the Excel team in the early ‘90s. “The way you are using Excel causes errors, creates incomprehensible spaghetti spreadsheets, and makes me want to stab out my own eyes. Enough of the =VLOOKUPs with the C3:$F$38. You don't even know what that means.” ~ learn more

Computer chip with built-in human brain tissue. “Last year, Monash University scientists created the "DishBrain" – a semi-biological computer chip with some 800,000 human and mouse brain cells lab-grown into its electrodes. Demonstrating something like sentience, it learned to play Pong within five minutes.” ~ learn more
big ideas 📚
White paint to help cool a hot planet. A professor of mechanical engineering at Purdue University has created the whitest paint on record. “The paint’s properties are almost superheroic. It can make surfaces as much as eight degrees Fahrenheit cooler than ambient air temperatures at midday, and up to 19 degrees cooler at night, reducing temperatures inside buildings and decreasing air-conditioning needs by as much as 40 percent.” ~ learn more

I have not been closely following this case and also am not an attorney, so it’s surprising to me that the problem was sales to professional investors rather than consumers. But there’s some logic buried within. “Institutional sales of the tokens violated federal securities laws, but programmatic sales did not, a court ruled.” ~ learn more
