Has this been a soul-searching moment for the fact-checking industry? Everything Harris says came, or is coming, true. And so much of it was labeled as "misleading" or "lacking context" at the time, on the grounds of "but he said he wouldn't!" (see, e.g.

Last week in Minnesota, I watched ordinary people risk their lives to protect their neighbors. In the process, they not only won a significant—though not final—victory against authoritarianism, they proved virtually every MAGA social theory wrong. (gift link)

During the pandemic, the US implemented the most effective social welfare policies in our history -- programs that worked because they were big enough, simple, and universal. And then we withdrew them. This remains imo the central economic-policy story of our times.

So. I think it's important to share news about what's happening. But I'm trying to square that with the other reality that it contributes to doomscrolling. I think we need to start putting these things into context and talking about what we are learning or what we should take away from it.

post a 🚨 spoiler 🚨 iff you've never seen this!! write f() for the floor function i.e. round down to an integer and d() for the divisor function i.e. # of divisors Consider 5: f(5/1)+f(5/2)+f(5/3)+f(5/4)+f(5/5) = 5+2+1+1+1 = 10 d(1)+d(2)+d(3)+d(4)+d(5) = 1+2+2+3+2 = 10 Coincidence?

according to

the first usage of the word “sewerage” dates back to 1834. other words first used that year include humoristic, optimistic, and self deprecating, and i feel like that explains so much.

Voted by mail? Check your vote status (google "vote status" + state). Voting in person? Check your registration (
vote.org
). I once thought I was registered and wasn't. I once had a mail-in vote not accepted the first time. It happens. Already did? text 5 friends a reminder to check theirs!

It turns out that the new Desmos 3D can show vector arrows and has a built-in cross-product operator. The d/dx and d/dy functions successfully compute partial derivatives. Great for plotting surface-normal vectors #iteachmath ♾️ Animated gif:
