American politics makes a lot more sense when you realize that the GOP is afraid of pissing off the GOP base, and the Dems are afraid of pissing off the GOP base, but neither party is afraid of pissing off the Dem base.

How about we shut down the government for this very popular and specific goal and then, hear me out, we hold out for like a month and a half and then, ok this part is important, after a watershed election where we ran the table, ONLY THEN, fold and don't get the one thing we said we wanted.

My 2.5 year old was with me and suddenly shared a few words that were both profound and silly, as toddlers do

A poem delivered by my 2.5 year old that encapsulates parenthood
My 2.5 year old Nadia told me some lovely sentiments as we walked today.

Rafael Veraza said a news conference organized by the coalition Sunday afternoon that he and his wife were on the way to do their weekly grocery shopping at Sam’s Club when they heard sirens and the whistles that have become the common signal of the presence of federal agents in the area. When they realized that the big box store was at the center of the raid led by Bovino, they decided to turn around and leave the area, Veraza said. As they were attempted to leave the area, Veraza said federal agents pepper sprayed his car without warning. Since his window was rolled down, Veraza said he was hit straight in the face with the chemical agent. “We’re not protestors,” Veraza said. "We were not even attacking them.” Veraza said he did not realize that his daughter was also exposed until his wife told him to pull over. Veraza said his daughter couldn’t open her eyes and appeared to be struggling to breathe. The whole family went to get medical treatment, he said. “We were trying to leave," Veraza said. “I was minding my own business."

“I want you to understand what it is like to live in Chicago during this time.”

aphyr.com/posts/397-i-...
I want you to understand what it is like to live in Chicago during this time. Every day my phone buzzes. It is a neighborhood group: four people were kidnapped at the corner drugstore. A friend a mile away sends a Slack message: she was at the scene when masked men assaulted and abducted two people on the street. A plumber working on my pipes is distraught, and I find out that two of his employees were kidnapped that morning. A week later it happens again. An email arrives. Agents with guns have chased a teacher into the school where she works. They did not have a warrant. They dragged her away, ignoring her and her colleagues’ pleas to show proof of her documentation. That evening I stand a few feet from the parents of Rayito de Sol and listen to them describe, with anguish, how good Ms. Diana was to their children. What it is like to have strangers with guns traumatize your kids. For a teacher to hide a three-year-old child for fear they might be killed. How their relatives will no longer leave the house. I hear the pain and fury in their voices, and I wonder who will be next. Understand what it is to pray in Chicago.

Let's make AI jealous.
Write what Al can't touch.
Humans can think with their heads, hearts, and bodies.
Try moving your hands.
It's fine if your mind remains a jumble.
Ideas scattered across the paper.
Sometimes they connect by chance, and something new is born.

Pilot had a massive ad spread in a jp newspaper with "make AI jealous" and "write what AI can't touch" written on it

Anyway I think everyone should own a Pilot kakuno pen
A photo of a newspaper advertisement, showing a zoomed in photo of a hand holding a Pilot brand fountain pen. "Make AI Jealous" is written in Japanese next to the hand, with "Write what AI can't touch" in English underneath.

I made a little demo for revealing an image behind some mouse movement! I think it could be a cool web component but I'm too lazy to do that right now.

Mouse reveal image
Either move your mouse around or click to reveal what's in the blurred image!...
