I don’t think anyone is prepared for what they just did w/ ICE.

This is not a simple budget increase. It is an explosion - making ICE bigger than the FBI, US Bureau of Prisons, DEA,& others combined.

It is setting up to make what’s happening now look like child’s play. And people are disappearing.

I've been banging this drum for years now, I know, but Zohran's Big Night is a clear illustration of the power of giving people a vision of the future that boldly contradicts the rhetoric of Republican fearmongers. Not just "disagrees on policies," but actively paints a different image of the world.

Am I the only one who has to restart my Mac after screen sharing using *any* app? The purple “you are screen sharing” icon never goes away otherwise and other stuff breaks.

His mother says he has been tortured by authorities at the airport. The reason, if any, for his detention is not known.
A New Hampshire man with a green card was detained by immigration officers at Logan Airport and is being held by U.S. Immigration and Customs Enforcement at the Donald W. Wyatt detention facility in Central Falls, Rhode Island.

Back in the mid-20th century, the FBI could place an individual under surveillance solely for being LGBTQ. This is what enabled the anti-queer witch hunts of the McCarthy era. Now, DHS permits surveillance of LGBTQ people again. Just being queer makes you a suspect. www.advocate.com/politics/dhs...
DHS quietly eliminates ban on surveillance based on sexual orientation and gender identity
The DHS quietly updated its policy manual earlier this month, removing LGBTQ+ identities from the section prohibiting surveillance based solely on immutable characteristics.

What does it mean for something to be Turing complete?

I answer this question, and more, through a series of fully interactive Turing machine simulations! Play, pause, step forwards and backwards, and even write your own Turing machine programs in my latest blog post.
