ironic that people say Bluesky is dying because i read this post and died
A dictionary, a sewer district, a federal agency, and some random dude walk into a social media site. I don’t have a joke, it’s just a description of BlueSky.

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. davisvanguard.org/2025/05/3hou...

We have had nearly two decades of panic about Free Speech on Campus and not a single case, not even the ones they made up, were as bad as what's happening now
This is the text of the email just sent to hundreds of international students telling them that their visas have been revoked due to activism or social media posts.

This is a good thread by one of my "trusted sources," @polotek.bsky.social.
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.

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

(a) stunning visual. (b) any differential geometers able to weigh in?
I have a legitimate technical question for differential geometers like @diffgeom.bsky.social on how to map a hemisphere to a closed connected surface while still preserving a particular sorta-Euclidean metric/distance. Here's a Desmos graph that kinda illustrates this goal. All input is welcome 😁🧮♾️

according to @merriam-webster.com 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.

Can you find a Pythagorean Triple containing...
• exactly one multiple of 5?
• exactly two multiples of 5?
• three multiples of 5?
• no multiples of 5?
Any conjectures?

Wow, I had no idea about this stat. The whole thread is gold.
Maybe its ok to cut 75% of federal employees because there are so many of them? No.
We have about the same number of feds as we had in the 1960s. As a percentage of the population, they are at historical lows. (We actually need more employees, esp. younger employees, but good luck recruiting them).
