What is this all about?? Let me try to explain. It's important, because it's actually about @seasocialhousing.bsky.social and it's about Alzheimer's and heart disease and asthma, and rich homeowners keeping you sick and housing rare and unaffordable. And what you can do about it THIS MONTH.

For ICE to build concentration camps quickly, they're leaning on this Dept. of War program WEXMAC TITUS helps contractors bypass the traditionally lengthy government contract bidding process

NEW β€” An obscure Navy contractor program is making Trump’s plans to quickly build out and supply immigrant concentration camps around the country a reality.

Here I explain WEXMAC TITUS, an acronym you need to understand:

It's a war and the American people are the enemy. Can't do the fake "no they're just after the bad guys" after you shot two people for no good reason. bsky.app/profile/ndre...

It’s worth walking people through the logic, because it doesn’t get repeated enough from the top:
1. There is no β€œimmigrant crisis”. This is a panic instigated by racist slurs from a President’s that, even very recently, decent white people would have admitted were shocking and unacceptable.

Minnesota National Guard rolled up, shot a hard stink-eye glare at the ICE goons, then stood with us, handing out pizza, hot chocolate, and coffee.

I am serious. The Guard literally just stood there, squared up to ICE: "You don't get to touch them."
But with us protesters, they let their guard down.
They were paying attention-not on autopilotβ€” reading the room, noticing fear, cold, and exhaustion, then responding with food, warmth, eye contact, and respect. Their smiles and nods said: "I see you. You matter. You're not alone."
Seeing strength used as a shield instead of a weapon was incredibly moving.

This is great. For one thing, protesters are safer in the presence of National Guard soldiers by orders of magnitude. Second, the approach embraced by the Minnesota Army National Guard makes ICE and CBP look so incredibly small and weak.

Minnesota National Guard members have arrived at a federal building and were directed to distribute donuts, coffee, and hot chocolate to anti-ICE protesters. Guard members were issued reflective vests so they would not be mistaken for federal agents.

BTW, if Senate Dems want technical reforms, here's one: amend 8 USC 1357 so DHS agents do not have power to arrest without a judicial warrant unless they are GS-1811, grade of GS-13 or higher.

Real criminal investigations would be unaffected, but CBP & ICE goon squads would be severely limited.

Something I've been trying to impart on people is that the ICE occupation in Minnesota is both an ethnic cleansing and an ideological terror campaign. It's clear that the second part has utterly failed; the community is not terrified. But ICE is now desperately trying to salvage the first part.

Something important to understand about ICE thugs in the Twin Cities is that they're harassing innocent kids and parents at bus stops and schools every single day. Even after the Pretti shooting. It's terrorism.

Something weird about this one, though - there seems to be a larger scale checkerboard pattern in the noise?
Or maybe it's just an artifact of downsampling?

I live an hour north of Minneapolis and they’re here too. They’re rounding up workers in chicken processing plants and breweries.

Opinion | I'm a Minneapolis sociologist who studies violence. Here's how ICE observers are helping. Research into how violence occurs shows that disapproval from the people around you can help reduce it.

For @msnownews.bsky.social, I wrote an article about how ICE Watch is grounded in sociological theories of violence prevention.

The reality is that most men will only commit public violence in extremely specific scenarios and ICE Watch disrupts the conditions necessary for escalation.

Another question I came here with was: how effective are the whistles and honking? Does it stop abductions? And the answer is, surprisingly to my cynical self, yes, and often. I have talked to so many people who have successfully interrupted kidnappings.

I have been actively involved in protest movements for 24 years. I have never seen anything approaching this scale. Minneapolis is not accepting what's happening here. ICE fucking murdered a woman for participating in this, and all that did is bring out more people, from more walks of life.

I've been here 24 hours, but already with what I've seen, well, I genuinely believe we're going to win. People here are well aware that what happens here impacts the entire country, that it sets the tone for resistance. ICE is angry, ICE is terrified, of how deeply unpopular it is.

I came to Minneapolis to report on what's going on, and one of the main questions I showed up with is "just what is the scale of the resistance?" After all, we're all used to the news calling Portland a "war zone" or whatever when it's just some protests in one part of town.

22.01.2026 03:58 πŸ‘ 15482 πŸ” 5774 πŸ’¬ 141 πŸ“Œ 1554

National media should really be covering the fact thay every major school, museum, and arts institution in the Twin Cities, and hundreds of local businesses are closed tomorrow to protest federal occupation.

Nothing like this at this scale has happened anywhere in America anytime in living memory.

In practice I've just used the quadratic formula to get one of (u, v) and then there's a rational-linear expression for the other, but that always seemed a little inelegant.

Exterior algebra is handy for setting up the quadratic formula for this tho!

I don't know if there's a way to do it all in vector / GA arithmetic since it's a nonlinear mapping (just as there isn't really a way to transform to polar coordinates and solve for (r, ΞΈ) as a vector). It does seem like there should be a way that's more symmetrical between u and v, though!

This is a staggering amount of money. It’s bigger than the Department of Transportation spending on all infrastructure. It’s bigger than all of the federal R&D done for both the military and all federal science agencies. Disgusting.

anil isn't kidding. this level of transparency and detail β€”Β talking to voters like adults β€”Β is remarkable. i would imagine it also helps people feel like they are part of something bigger. and, christ, mamdani is insanely charismatic and good on screen. like, you just want to watch him talk!

We don’t live in a neutral marketplace of ideas. We live in an attention economy shaped by algorithms, tribal identity, outrage incentives, and profit models that reward engagement over accuracy.

The danger isn’t just that people believe lies. It’s that entire communities become locked into belief systems that can’t be challenged, where loyalty replaces evidence, and disagreement feels like betrayal. That doesn’t just distort truth, it breaks trust.

The conditions that have led to what’s happening in the US today exist in democracies around the world.
They are an inevitable outcome of our collective failure to adapt to fundamental changes in the information ecosystem on which our democracies were originally built.
