Once again, Congresswoman Tlaib is a real one.

And um. @debbiedingell.house.gov ? Could you just not (support manufactured war on Iran ffs)? And say that publicly? Seems like not too much to ask. Thanks in advance, I hope, but get on this.
UPDATE — Here are the 13* members of Congress who have so far signed on to efforts against the Trump-Vance admin's moves towards war on Iran

*Missed Welch initially

Outreach for these resolutions still going on inside Congress, watch for numbers to possibly change tomorrow

Especially if you're on the fence about it, protest today. Fascism is isolating and lonely. Its very goal is to make you feel like you're the only person unwilling to accept a cult of personality. On days like today you fully realize there are more of us than there are them. You will feel better.

Have you seen Logical Redstone! I found out about it when my 10-year-old ran up to me yelling "Mommy! Mommy! I made a half adder!!!"

Love how well it explains these concepts: www.youtube.com/playlist?lis...

Picked this book up on a whim at Vault of Midnight, and had so much fun with my 11-year-old making our first batch of dumplings together. I wish more kids cookbooks were written like graphic novels!

I've done some retrospection and written up a history of my WordPress contributions. Next week marks a decade since I became a core committer. Now that I've been laid off from Google, I'm looking to find a sustainable way to continue contributing:

Is the WebDev Arena truly measuring webdev coding ability?

This ML coding benchmark *requires* React/Tailwind and completely breaks with vanilla JS/other frameworks.
The second-order implications of models competing on this narrow definition of frontend web development are rather troublesome.

This a phenomenal article about improving INP on a real react app. 👏

A fantastic step-by-step account of all the things they did to slowly but surely inch it forward. And not shying away from showing the things that didn't work!
