This is just insane. It’s only a matter of time before DHS kills another innocent person here.

Minneapolis should press its momentum and demand not only withdrawal but start talking about the need for immediate reparations, loudly, with the total certainty that only winners have. "You have wronged us terribly and must pay recompense" and let them argue the second part.

It's for sure a double edged sword. But there really is no such thing as social media (or any site hosting ugc) without content moderation. There are different ways to implement the outcomes (e.g. how this place gives you choice about which filters you opt into). But even X moderates (albeit badly).

The work @samidh.bsky.social and I are doing at Zentropi is a good public example of this (and the one I'm most able/at liberty to talk about) but there is so much happening in this space right now.

AI is Removing Bottlenecks to Effective Content Moderation at Scale Zentropi's Dave Willner says LLM-driven technology can now accomplish content classification at the scale necessary for moderation on large platforms.

@techpolicypress.bsky.social was kind enough to host my reflections on just how far we’ve already come with AI-assisted content moderation.

We’ve got a long way to go, but the difficulties that used to serve as (legitimate) excuses are fading fast.

Scrolling through the photos of Pam Bondi's "Minnesota rioters," it's just hero after hero. Every photo includes a cowardly DHS agent with their back to the camera.

Bondi thinks she's going to win the propaganda war with this shit, but it's never been more clear that they're losing.

People not in Minneapolis spreading the theory that Pretti was targeted in a hit do not understand the damage they’re potentially doing. Insanely irresponsible

Guys maybe the number one obstacle to organizing here in Minneapolis is the unfounded fear that if you get involved, DHS will put you on a list and assassinate you. It leads people to avoid organizing or act in ways that are completely detrimental to organizing. Please please do not spread that fear

Yep, the shootings were clearly great politics for the White House just like the White House said.

Zentropi Now Labels Images Building guardrails for visual content just got a lot easier. Today we're launching image classification on Zentropi and announcing cope-b-12b, a multimodal model that powers this experience.

We just shipped image classification on Zentropi!

You can write your criteria in plain English, then analyze images against them at scale using cope-b-12b, a new multimodal model we trained

Critically, @samidh.bsky.social used it to make a cat detector: blog.zentropi.ai/zentropi-now-labels-images/

A lot of the time, specific people and organizations are the problem, and an unwillingness to say that clearly is, itself, a part of that problem.

I have done this I have an idea-capture skill that formats and organize rambling ideas into a nice write ups in a section in the Obsidian vault I have claude keep stuff in. It's great, was easy to build, highly recommend. Used the skill-builder-skill anthropic released to build it :)

Alex Pretti’s Sig handgun has history of accidentally firing β€” offering possible clue to why Border agent shot him

From the NY Post. You know they are really scrambling when they are running "The gun was no angel" stories.

Those blaming failure to "reduce tensions" by telling protestors to stay home want you to be ok with/forget that masked federal thugs just murdered a man in broad daylight

It's not a time to reduce tension. It's a time to stand up in overwhelming numbers

They SHOULD be afraid of what happens next

NYT push alert: "A person was shot dead today during a struggle with federal agents in Minneapolis, according to officials."

NYT push alert: "A person was shot dead today during a struggle with federal agents in Minneapolis, according to officials."

By who? Who shot the person dead? You saw the video. We all know a federal agent shot a man dead who was prone on the ground. Also, it's not "according to officials." It's according to verified video seen with your eyes. Not saying what anyone can obviously see with their eyes is a form of lying.

Let’s be clear about something: This was an execution.

Rep. Moulton voted No on the Homeland Security approps bill this week.

Not a single Democratic Senator should vote Yes on that funding bill now. We cannot provide more resources to ICE or CBP. None of this is acceptable.

Why is Dem leadership not on the ground in MN? If the answer is β€œpolls show Trump’s disapproval is only -15 on deportations, but -25 on prices,” thats a Bad Use Of Polling and a complete failure in their capacity as leaders to lead public opinion and fight for democracy and the rule of law

The way to reconcile this is their aspiration was always to put down a slave revolt, not fight in one. bsky.app/profile/osit...

What is happening on the streets of the US with β€œLaw Enforcement” agents killing people is disgusting, horrific and outrageous. I don’t have a take. I don’t have words. I don’t have advice for how to fight back. I am just grieving.
