Hoboken cut traffic deaths to zero, thanks in part to paint & posts. So what’s the excuse? "we'd rather kill pedestrians than remove a parking spot”? “we’d rather kill pedestrians than slow traffic"? This should be the bare minimum every city does. (@cvillecityhall.bsky.social 👀)

The 2025-2026 #academic job market season is upon us. Here are some resources and #job postings for #faculty and #postdoc positions for those in Information/Computer/Social Sciences, and related fields. Will update the list as more #jobs are posted. 🧵(0/n) #AcademicChatter

This study not only asks human experts to score AI- and human-generated ideas, but also to *execute* those ideas (a nice setup!) AI-generated research ideas *sounded* better (high estimated effectiveness score) but their score drops below human ideas after the execution. arxiv.org/abs/2506.20803

AI may be significantly narrowing (favoring established scholars) science by affecting how scientists identify experts, key papers, reviewers, ... www.nature.com/articles/d41...

@nat4cville.bsky.social spent 10min during the discussion about demolition of a historic house on Wertland Street to talk about the urgent need for affordable housing. I clipped 6min of it. This is part 1/3.

when you learned Git for the first time, what resources did you use? Did you like them? Mostly looking for answers from folks who learned Git in the last 5 years or so. Looking for resources to potentially add to the Git website

I just (re-)started the Charlottesville area R Users (CRU) group. If you're in the Charlottesville area come out to CRU's first in-person meetup Sep 24 at 6pm at the UVA School of Data Science. #Rstats More info, and register (free) here: luma.com/9zespmac

Results so stunningly clear they inspired this classic xkcd (xkcd.com/2400/):

Q: How are resources consumed in transportation networks, and how does this shape the overall functioning of the system? We introduce the minimum-cost percolation framework and apply it to the U.S. air transportation system using publicly available data. 🔗 www.nature.com/articles/s41...

Cville peeps, it's time to make your voice heard! Charlottesville city council is considering an action that will, in effect, criminalize homelessness in city limits. We keep each other safe. Act now—there are simple steps in the thread below—and tell council to reject the police chief's request!

We are starting to see higher total cumulative annual mentions for entire organisations on Bluesky than on Twitter. Below are mentions of all research ever published by @leibniz-zmt.de. Bluesky is higher than Twitter in 2025.

We are thrilled to announce the keynote speakers for #CIKM2025 🥳 Haesun Park, Sihem Amer-Yahia, and Yong-Yeol Ahn ( @yyahn.bsky.social ) will share their insights at #CIKM2025! Stay tuned! More info: cikm2025.org/program/keyn...

I've moved! ❤️ → 🧡💙 "Hoosiers" - "sier" B → C & town → ville ... And the “smaller and smaller cities” streak lives on. Grateful for IU colleagues ❤️ and excited for new adventures at UVA School of Data Science, aka the "school without walls"! 🧡💙

At Sunrise school (Charlottesville), but it's nothing special about this school, the parking lot and drop-off zone sprawl across as much space as the school itself. Yet, bike racks are in short supply and all the cars make it feel unsafe. If we want kids to walk/bike, we need to make it possible.

Is AI just a guy who frantically following a rulebook to rearrange tokens to convince us it can speak Chinese and do math? Or, if it can walk through them well enough, can it become a “real” duck? What if the guy, rulebook, and duck are all aliens?

An important piece on #AI generated #preprints and why it's important to consider their impact on scientific ecosystem. Some other important considerations related to this that are not covered in the article 👇 🧵1/14 #AI4Science #AI4Research #ScAISci #SciSci

Creating questions at a right level of challenge helps me learn nuances and go beyond surface-level understanding. But why not let students to do that? I created a pedagogical tool that lets students to create challenging questions that stump LLMs. Repo 👉: github.com/skojaku/llm-...

I gave a talk on Wednesday at the Bay Area AI Security Meetup about prompt injection, MCP security and the lethal trifecta. Here are the annotated slides from my presentation, including notes on my weird hobby of trying to coin or amplify new terms of art simonwillison.net/2025/Aug/9/b...

If you're using LLMs to automate things that involve private data, you really need to understand the potential security risks: simonwillison.net/2025/Aug/9/b... "Lethal trifecta" by @simonwillison.net

An interesting deep dive into the paper "Optimal dietary patterns for healthy aging" in Nature Medicine. youtu.be/LPXWCIFDkgM One take-away: healthful plant-based doesn't seem to work better than other patterns, but adding fish and low-fat dairy (~ "AHEI") seems to be the best.

NEW RESEARCH ALERT 🚨 TechEquity just published “Take the Mic: How Worker Voice Shapes Workplace Technology,” which explores different models of worker voice and why it matters.

Probably the best, but also the saddest, headline ever produced in the history of headlines.

Holy shit, they did it. They wrote the headline.

This is a great opportunity for installing better infrastructure, right? @livablecville.bsky.social @nat4cville.bsky.social

If you ask the new Grok (via grok.com without any custom instructions) for opinions on controversial topics it runs a search on X to see what Elon thinks I know this sounds like a joke but it's not. This genuinely happens: x.com/jeremyphowar...

What happens when we give people money to buy homes? It turns out one key factor determines whether housing becomes more affordable or more expensive... youtu.be/N_GLfxaYTYI

Not sure how many people know that X now doesn't show the reply threads or profile pages to non-users. Combined with the practice providing the links later in the reply threads (please don't do this here it's useless), most academic paper threads on X is useless for non-X users.

“Measles vaccination alone is responsible for half a percent of all US income this year, $76.4 billion. That is just from the reduced disease burden, it doesn’t include reduced medical costs.” Via @emollick.bsky.social www.aeaweb.org/articles?id=...

Nazi Germany did literally ban Nature: "Articles are often published in the London weekly scientific journal Nature containing outrageous and vile attacks on German science and the national socialist state. The journal must therefore be excluded from general use in the scientific libraries."

STAGGERING: This new study of 133 countries is the first to estimate the impact of all USAID’s work. In 2 decades, it has saved *92M* lives. Current cuts, if not reversed, are forecast to cost up to *14M* lives thru 2030. www.thelancet.com/journals/lan...

charlottesville spent most of a decade revising its zoning code. it held endless community meetings and gave opponents ample opportunity to make their case. they lost. but a handful of rich homeowners sued and have gotten the new code overturned on a technicality.

New paper hot off the press www.nature.com/articles/s41... We analysed over 40,000 computer vision papers from CVPR (the longest standing CV conf) & associated patents tracing pathways from research to application. We found that 90% of papers & 86% of downstream patents power surveillance 1/

6. That’s the dynamic I see it here. To what degree should corporations be liable for harms that they cause as judged by the best available science and a consensus among experts? If I can’t sue Philip Morris for selling cigarettes to kids without a double blind trial to prove harm, we are sunk.

1. People seem upset that I associated the language in Trump’s Gold Standard Science executive order with the science reform movement, in this Guardian piece. “Trump would have attacked science anyway” Of course. But it’s not Trump that is the biggest concern. It’s the courts.

The head of the FDA tells us they're taking a look at the dietary guidelines and that the food pyramid is out. The food pyramid has not been in use since 2011 when MyPlate replaced it.
