THE FINGER-TAKER’S SON

Whenever the king became displeased with one of his subjects, he would send out his soldiers, and before long the offender would find themselves in the basement of the king’s finger-taker.

The finger-taker claimed to be a persuadable man.

Today I saw ICE gas little white kids in the streets of Portland with chemical weapons. Imagine what they're doing to brown and black kids in the detention camps

Yes! Please read this article from @markhisted.org whose views deeply respect.
"We cannot return to the old way of trying to ignore power and politics — if we do that, scientists will just be run over and US science will continue to collapse."

If I were a blue state governor, I’d be looking into adding a bunch of tenure lines at my state schools.

I know that seems like “kick ‘em when they’re down,” but it’s more like “let academics who can escape to where they can do real work.”

Builds up your own schools AND protect US academic output.

1. The thing about science that these jokers don't understand is that science cannot be vibe-coded.

Whatever its flaws, the point with vibe coding is that you're trying to quickly make something that sorta works, where you can immediately sorta see if it sorta works and then sorta use it.
“The idea is to put ChatGPT front and center inside software that scientists use to write up their work in much the same way that chatbots are now embedded into popular programming editors.

It’s vibe coding, but for science.”
OpenAI’s latest product lets you vibe code science
Prism is a ChatGPT-powered text editor that automates much of the work involved in writing scientific papers.

This is personal too. My next-door neighbor growing up watched Fox, didn’t get vaccinated, and died of COVID.

I’ve heard enough locker room talk in my life that I know the primary problem is not the tone or contents of the msg, but the billionaire-owned media machine that demonized the messengers.
That the loss of trust was among Republicans could have been partly due to scientists seeming disrespectful to Republicans, eg. a Fauci & Rogan interaction led Hotez to say "If we fail to embrace our conservative brothers and sisters, and treat them with dignity and respect, we lose as a nation".

Apple & Google removed ICE tracking apps in their app stores.

TikTok reportedly suppressed videos criticizing ICE & the shooting of Alex Pretti.

Meta blocked Facebook groups tracking ICE & links to a database of agents that the government wants to keep secret.

Truth is brutal when you are complicit in supporting fascism in any form.
FUCKING BRILLIANT!

Tom Suozzi, 1 of 7 democratic congressman who voted to expand ice funding to 10,000,000,000, was confronted by protesters at a speaking event, and receives a vicious rebuke for betraying his country, his party, his constituents, and everything he claims to stand for.

Listen to this brave veteran. This is real America.
Ian Austin, an Army veteran, was arrested for protesting ICE in Minneapolis. But he’s continued protesting. Senior reporter @julialurie.bsky.social spoke to him.

“When they say, ‘Why would you be out here?’ How the fuck could I not be out here?” he says. “My nation is under attack."
