I'll say it again: If you're consistently finding ways to rationalize away Graham Platner's Nazi tattoo or embrace of Nazi content creators then you really are no different than those on the right who were trying to explain why Elon really wasn't giving a Heil Hitler

In general, yes, people need to let politicians politician as long as their glonzo hunt doesn't hurt policy. But I don't see a way out of the housing problem without breaking the exact attitude and power structures "stop PE from buying housing" reinforces.

Battle school is a dumb genre, but it is a remarkably less dumb genre if you shift it to a PhD from high school.

This has gotten even sadder as I’ve dug into it. The agent can see that I’m the tech lead on the project that produced it, and that I’ve said its perf. on this task was poor (about a prototype from a year ago). These are citations to an authoritative primary source so they survive all critique.

To clarify for the non-roboticists out there:

Two legged humanoid robots only stay standing when they’re powered and the control loops managing the joints and actively detecting the balance situation are all functioning.

Lose power? It keels over. All 120-200 lbs of it.

In the early 1930s the SA was roughing people up, creating chaos in neighborhoods, seeking to terrorize with the occasional killing. By the late 1930s it had been supplanted by the SS, which was much better trained.

I just don't buy arguments that all this cruelty against immigrants is a mean to some other end. It can be used that way, but it's worth remembering that Nazis diverted resources during wartime to make sure to kill Jews.

People are missing a big thing about the saga of the detained 5-year-old. When Vance calls the father an "illegal alien" it seems to reflect a little-known Trump admin move that attempts to nullify asylum claims before they are even heard.

This policy is a horror:

This line graph illustrates the percentage change in agency staff levels from the previous year for nine major U.S. federal scientific and health organizations between the fiscal years 2016 and 2025. The agencies tracked include the CDC, Department of Energy, EPA, FDA, NASA, NIH, NIST, NOAA, and NSF. For the majority of the timeline between 2016 and 2023, the agencies show relatively stable fluctuations, generally staying within a range of +5% to -5% change per year. However, there is a dramatic and uniform plummet starting in the 2024–25 period. Every agency depicted shows a sharp downward trajectory, with staffing losses ranging from approximately -15% to over -25%. The Environmental Protection Agency (EPA) shows the most significant decline, dropping to roughly -26%, while the National Institute of Standards and Technology (NIST) shows the least severe but still substantial drop at approximately -15%.

This is the most astonishing graph of what the Trump regime has done to US science. They have destroyed the federal science workforce across the board. The negative impacts on Americans will be felt for generations, and the US might never be the same again.

Having seen several abductions up close, it is really hard to convey how much the thing they’re doing is roaming in military convoys until they see someone who is alone and isn’t white, and then jumping out in large numbers, pulling them into a van, and screeching off, all in 90 seconds or so.

I really want ppl w/o Minneapolis connections to understand

You might've heard that Mpls public schools went hybrid bc so many families are in hiding. Well, a coworker just told me that today, during his kid's hybrid class, a kid's apt building was raided onscreen

He was a devout Christian and quoted the New Testament "synagogue of Satan" as part of his confession.

It is not harmless to repeat the anti-Jewish rhetoric that is written in Christian scripture.

This is stunning. Listen to this in Philadelphia.

There’s a GoFundMe for Jonathan Ross’s legal expenses for murdering Renee Good.

This violates GoFundMe’s Terms of Service. Everyone must report it.

Batman breaking gun meme. β€œThis is the weapon of the enemy. We do not need it. We will not use it.”

If someone is so awful that it could be justified to lie about them, then by definition there’s plenty of truth to condemn them with (as there is for JKR) and we’re stronger sticking with that. Being misleading undermines ourselves and the project of truth: it is the weapon of the enemies of truth.

🧡In my expert opinion as a researcher of vehicle ramming attacks, what has been publicly described in the video evidence does not support the claim that Renee Nicole Good was attempting a deliberate ramming attack when she was shot in Minneapolis on January 7, 2026. 1/7

So when authorities say β€œshe tried to run over an officer,” that is not a neutral description. It is a claim of intent that can be used to justify lethal force after the fact.

When the state kills first and invents the threat afterward, it is not policing, it is death squad behavior. /end

My dude one-hands the whole shooting because he’s got his phone recording in his left hand the whole time.

Never even moves to drop his phone to put a second hand on his pistol BECAUSE HE IS A CONTENT FARMER, NOT A TRAINED LEO.
