Interesting - *on the night shift*, early birds get c19 at a much greater rate than night owls. Wonder if it's the reverse for daytime jobs? pesquisa.bvsalud.org/global-literat…

A decade ago, Facebook let companies advertise to people who liked a competitor's page or group, and it was very cheap to do this. I'm sure it was profitable enough in the short term, but *many* brands stopped making pages & groups. I wonder what the long term cost was.

Want to reduce C0VID transmission in #schools this fall? Based on the new #ASHRAE Standards, this is the chart I'm recommending families and collective bargaining units use to lock in clean air. 1/15

There's basically no amount of money you can pay a developer (outside Apple) to say "set my iPhone alarm to wake me up on weekdays but please *skip* national holidays".

Unity: "we are going to track reinstalls and not charge you"... bizarrely ignoring last 6 years of Apple privacy changes. theverge.com/2017/4/23/1539…

There should really be a kind of contract law for "building on someone else's platform" - by now there are enough Unity/Google Maps/etc. rug pulls that you could imagine what platform owners might reasonably owe people who put years of work into them. Otherwise it's only serfdom.

I’m a fan of normal portrait lengths, so feels like something’s missing from the iPhone 15 pro max—an optic between 24mm and 120mm. That means you’re shooting 3x zoom using 10% of the sensor (1-4 megapixel depending how you count AI/quad Bayer stuff, but it’s not much!)

Lots of good arguments here. But mainly - CPI is getting overused as "affordability" when it's not... doesn't consider the cost of debt, and the economy recently is based on debt. e.g., car prices can go down while monthly payments go higher. open.substack.com/pub/mattstolle…

iOS measures "time in daylight" for myopia, though advice is strange. Myopia intervention studies adjust "time for recess". 120 minutes outdoors at school is not the same as 80-120 minutes total & also the dose-response goes past 2hrs/day. See ncbi.nlm.nih.gov/pmc/articles/P…
