With my husband's consent, I want to tell a funny story about birth certificates and zip codes.

My husband is a 3rd generation Polish Buffalonian. He's currently working on completing some paperwork that requires an original birth certificate - like the SAVE Act requires.

But of course it depends on what a kid is trying to do, and if that’s something about how the change in y is 28, then by all means let’s notice what the change in x has got to be.

I am going with general purpose tools, which here seems like writing an equation and subbing that known y-value

and I can tell you thatβ€”having turned it offβ€”I am trying to develop new email habits. I unsubscribed from all the commercial and newsletter stuff I don't actually read, and I do two passes on emails nowβ€”the first to STAR things I actually want to deal with and delete the rest. Second to read

it really is bad that they have made it mandatory to get AI summaries of your emails if you also want to apply "Important" filters to them.

I have no solutions, only empathy

ICE in Minneapolis | Documenting "Operation Metro Surge" Photography from Minneapolis as thousands of federal agents arrive.

Since December i’ve been taking pictures in Minneapolis as thousands of federal agents and officers descended upon my city. Photos regularly get posted on my site first along with many that never make it to social media.

might not my advocacy for not getting personally punched be a guide to others' advocacy for not getting punched themselves?

might not my personal relief from the punching give me the time and energy to advocate more generally?

"don't advocate for the bully to stop punching you in the face. advocate for the bully to stop punching anyone ever again."

but these are not mutually exclusive.

must I wait until the bully is done punching forever to feel some relief?

We will advocate for the harm to stop here.

We will celebrateβ€”and rightly soβ€”when it does.

And also we will advocate for the harm to end everywhere forever.

I feel a bit emotionally out of step with most here, but I'm kinda in the mood of "Dance in the streets, but bring your whistles"

Pass it on: Let’s all go out to dinner tonight and show our restaurants we love them. If Homan says they’re going, let’s celebrate. It could be a VE Day style all-cities love up. What say you Minnesota?

AL, Logical! A Young Adult Graphic Novel It's like a math circle, but in a haunted multi-dimensional mansion where a brave artist finds a restless ghost of a mathematician.

Help us bring to life AL, LOGICAL by Xavier Golden and @johngolden.bsky.social, the first graphic novel to be published by Natural Math. I love comics, and Xavier's beautiful panels are adventurous and cool. John's decades of math ed design shine here. Let's go! www.kickstarter.com/projects/nat...

After a face-saving period of time, the prediction seems to be coming true.

Of course we'll need to see it play out, and the source of truth will be the citizenry not this man with his ill-fitting suits and lie-filled mouth.
