I don't live in Palo Alto so early on in my postdoc I was determined to learn the roads on campus and would leave my phone in the trunk when I had to drive/walk to meetings. The number of meetings I ended up just not going to because I got lost is greater than zero. But I know the campus now.

If you're an institution looking to bump up your US News ranking, I just want to point out that every school I've been affiliated with (SDSU, NYU, Harvard, Stanford) has gone up in ranking. I'm not saying it's causal — but you could hire me and find out.

I had my mid-tenure review recently. Today, the child asked me how it went, and I told I needed more awards and more grant money. So she gave me this award. Which is fine, I guess, but I'd rather have the money.

New research published in the medical journal JAMA on deaths in ICE custody shows that “systemic weakness” in medical care at the agency has become more serious in the past two decades, physicians say. DHS did not immediately respond to a request for comment about the research.

Death rate in immigration detention has reached a 22-year-high, raising physicians' concerns
A report in the medical journal JAMA said the most recent spike in deaths took place in a system with “longstanding failures” that were compounded by Trump administration policies.

The child and a bunch of her friends got landlines recently, and I just overheard her explaining to her friend how to hang up. "There's no button. You have to put the ear thing on the other part of the phone. No, it doesn't beep. You just put it there."

There's a service that creates an AI-generated "opposition dossier" on you before you go up for tenure so you know your weak points, potential critiques, and comparators. Bruh — I'm sure your calculating rock can do a lot of things better than me, but I've been criticizing myself for four decades.

Users opt in and we use a smartphone app on their own devices so they can turn things on and off. Some users will request data deletion but mostly because we automatically delete their data if they don't open the app in a while. It's rare it's intentional but obviously respected when they do.

And obviously combine that with the expectation of privacy (the spatial data I have users consent to that data and we are clear we are collecting it so there's never an illusion of anonymity).

I think style is just one extracted feature. They also get the LLMs to find identifying terms like user school or subject of research, etc. I think most worrying is how little effort it takes to do tons of people. With spatial data, it's fairly easy but you need to be focused on one person/area.
