@zohrankmamdani.bsky.social, could you please establish an official NYC Mayor account on Bluesky and post everything your office is currently posting on X over here? And please remove all city accounts from X, which has become a CSAM creation and distribution site? No money for Musk, ever, please.

I'm teaching "Intro to NLP" this semester and am finalizing which topics to include. I haven't taught or taken this class in a decade! Which topics are you including in your NLP courses these days? I'm curating a small list of similar courses here: www.are.na/maria-antoni...

Congestion pricing is an unqualified success in NYC. It would be great to see it expanded to every city with decent public transit options. www.nytimes.com/interactive/...

Congestion pricing is a heckuva street safety strategy www.nytimes.com/interactive/...

The end goal of Grok sexual harassment is to make women afraid to be visible. It’s a punishment for daring to exist in a way the perpetrators can’t control. There’s no one solution to this, because the problem isn’t just technological. It’s cultural. It’s misogyny. This is just one expression of it.

Really past the point of negligence now

As I work on my little word shift package as a side project, I keep thinking of the phrase "artisanal programming"

✨ New Polars features: `min_by` and `max_by` 💡 Get the first (or last) value of a column ordered by another expression 🌊🦄 Narwhals will have this feature too, making it available to @arrow.apache.org , pandas, @duckdb.org , and more

I know some tech reporters follow me; seriously what’s the deal here? Someone please explain

I know this is yesterday’s news and feels relatively unimportant now but just want to note that this is ongoing and X and xAI continue to do absolutely nothing about it despite being able to end it by pressing a single button.

People are going to try and lure you into debates about whether Maduro was a good guy or not and the thing is, it doesn’t matter for the purposes of discussing whether violent kidnappings and extrajudicial murders by the US government are ok. No, they aren’t! End of convo.

The action in Venezuela is also another consequence of how weak Congress has become. President saw no need to even attempt to build support or justify his actions.

"child porn" does not exist. That's an outdated phrase that has been replaced by the far more accurate "child sexual abuse material" because *checks notes* abuse is NOT porn. Porn is made by consenting adult performers!

Best thing I’ve read this morning, from a human rights lawyer in Mexico. Translation is in the ALT-text.

That's it, i'm no longer doing any of my banking on X

just gonna drop some links to a few papers of mine about AI-CSAM and the law here, for no particular reason cyber.fsi.stanford.edu/news/ai-csam... (May 2025) partnershiponai.org/hai-research... (November 2024) www.lawfaremedia.org/article/addr... (February 2024)

Any other product that called itself “MechaHitler” and produced CSAM would be immediately withdrawn from the market, discontinued, and its creators facing legal consequences. But for some reason, the guy who gave the president a quarter of a billion dollars is not worried.

The media needs to recognize that there is a marked difference between the endemic problem of CSAM being posted to social media platforms and a platform giving users a tool to actively create CSAM.

I have a short essay in Communications of the ACM about the new scraping wars between AI companies and websites, and how the fault lines are less clear than they were last time around. cacm.acm.org/opinion/ai-s... 1/3

It is kind of wild that no big media outlet has busted open the story of who is making DHS' posts on X. Whoever that may be is certainly plugged into hardcore white supremacist internet propaganda with a harder edge. "Groyper" would be underselling it. This is Daily Stormer-tier sludge.

Hong Kong financial regulators pushed Meta on why it wasn’t verifying the ID of financial advertisers (a very common source of scams) Meta staffers boasted about how, through “skillful negotiation,” it redirected HK to organizing an anti-scam charter signing event requiring no product changes.

For my last post of 2025, here's a look at a network of websites and social media accounts hawking #resistance- themed garments, frequently with slogans regarding U.S. National Parks. As it turns out, the websites in question are likely operated from China. www.conspirator0.com/p/how-not-to...

Democratic erosion, but for public health. People will die.

I was looking into Voronoi diagrams for a side project, but I just could not follow the details. So I do want I am wont to do and dove into the details, working out a lot of geometry and making too many figures. HTML: betanalpha.github.io/assets/chapt... PDF: betanalpha.github.io/assets/chapt...

Every year I look forward to this @visuals.axios.com chart. So good. www.axios.com/2025/12/29/g...

How much do you think it costs Meta to store and host static images as videos because people (correctly?) believe videos get more algorithmic traction than images, and so they make photos into videos just to try and game the algorithm

I keep getting logged out of Bluesky every few days. Is there a new setting for how long a session persists, or is this a bug?

Wildly different things, tasks, techniques, subspecialties being lumped into "AI" and then being conflated with each other, doesn't help. Different types of models vs the techniques to train them vs the tasks they are supposed to accomplish, all under "AI".

"the researchers found that withdrawing support for rapidly advancing mRNA vaccine technology could result in over 49,000 preventable deaths annually among patients diagnosed with four major cancers"

I thoroughly believe more people would build for #atproto if the documentation wasn't so dry and technical. I learned more from @nickthesick.com's 5-minute blog post about lexicon publishing than I did from the official @atproto.com docs. nickthesick.com/blog/Publish...

🚨🚨 New paper out! With @colltoaction.bsky.social, @fralotito.bsky.social, and a bunch of offline co-authors 🙂 we published "HIF: The hypergraph interchange format for higher-order networks" doi.org/10.1017/nws....

the analogy I use with friends and family all the time is the jump from collegiate to professional sports. as soon as I explain it that way, it clicks in their brains what the academic job market is like.

Threads is effectively shelving their fediverse integration, after it saw marginally little use Zuck has played the game well, harming both open protocol movements while growing his platform, getting good PR and distracting regulators connectedplaces.online/reports/fedi...

The ACM Digital Library, where a LOT of computing-related research is published (I'd say at least 75% of my own publications), is now not only providing (without consent of the authors and without opt-in by readers) AI-generated summaries of papers, but they appear as the *default* over abstracts.

The University of Washington's Center for an Informed Public is looking to bring on new postdoctoral scholars to join our research community starting in 2026-2027. Come collaborate w/ our amazing, interdisciplinary team working to understand & help people navigate our complex information ecosystem!

Since 2020, our team has iterated on a model for “rapid research” to help surface, analyze, & resolve rumors about election administration. This work demonstrates an innovative role for researchers to support public sensemaking during rapidly unfolding events. uw.pressbooks.pub/rapidresearc...

New from me! After we reached out to the owner of these deepfake porn sites, they were removed offline and he deleted his socials. Each time a site goes down, it's a win for me. Hopefully this guy never tries to get them up and running again. Check out our investigation!

Someone had to do it. Reddit is challenging Australia's ban on information access for kids. Supporters will argue that the ban is justified. But no one should doubt that this is a drastic, unprecedented restriction on freedom to seek and impart information. Court review is definitely warranted.

My second post about researchers’ rights to scrape data under DSA Article 40.12 is up! This is dense with legal arguments for researchers to use if they get sued. Or to show their lawyers before that. www.techpolicy.press/how-the-mean... verfassungsblog.de/dsa-fine-x-r...

The human cost of Trump's gutting of USAID: By the time Tor Top’s mother was sick with cholera, the nearby clinic had been shuttered for weeks. He bundled her into a canoe & paddled toward the nearest hospital, 8 hours away. Less than halfway into the journey, his mother died. New, @propublica.org

New paper out in @science.org! We unveil the online manipulation market with the Cambridge Online Trust & Safety Index (COTSI). We show in real time the cost of purchasing fake accounts across every social platform around the world - so they can be held accountable www.science.org/doi/10.1126/...
