When I get down about what has become of journalism, of speaking the truth, I think of Jamal. I lost my Washington Post job. Jamal lost his life. Both of us — all we wanted to do was write and help people.

If you think an artist's style looks like AI but you can scroll back through their portfolio and see them doing the same work before 2020, congrats, you're not looking at an AI grifter. You're looking at one of the original victims whose entire style AI stole.

In the year I've been working w/ air pollution regulators on data center on-site emissions, I've seen almost no acknowledgement of this trend from energy-side advocates of data center buildout. This isn't just bad actors-it's a corporate playbook and a roadmap to a future of unconstrained emissions.

I DID A THING this morning. A piece of burocracy related to my dad's passing last July. It took 20 minutes (actual time: five minutes, plus figuring our how to use a scanner). I choose to view this as a sign that my do-things part of the brain is coming back online.

Hello #MathSky! A while back there was a study showing that it was better to include more support in a calculus class for underprepared students rather than have them take more prerequisites, I believe because of the attrition associated with taking more courses. Anyone remembers and has a link? 🙏🏻

If I worked in the UK, it would be much easier for me to apply for grants, and there would be many more grants I could apply for. On the other hand, I have had tenure since 1990*. I'd rather have that. *Technically 1993, the first three years were tenure track.

California just banned child marriage! Yup: until recently, California was one of only three states - along with New Mexico and Mississippi - with no minimum age to wed. A child could marry as long as they had parental consent and a judge’s approval. calmatters.org/politics/202...

Strongly disagree. I'm 1000% opposed to the ideology of "AI", the industry, all of it. I'm also someone with experience of mental illness/distress. But this neoliberal narrative of choice (blaming) individuals seeking help, when none is available, plays into their hands, and reproduces ableism

If I were running a university where staff spent weeks and weeks of time putting grant proposals together only for UKRI to feed them into LLMs without informed consent—effectively theft of the time and work—I’d be taking serious action to defend those staff. But I’m not running a university, so

An ERC committee member said in front of a crowd that there was already a triage of applications based on the applicant's CV. Now he expected that AI would be used. Preparing an ERC takes MONTHS, you have to work out the financial plan as well as the science. Imagine being doomed from the start.

Hill I'm ready to die on: whether for grants or articles, review by AI is not *peer review*. Review based on a 1st scan by AI without actual reading of the grant or manuscript is not peer review either.

Today I was trying to explain to colleagues why knowing the answer to a question isn't necessarily enough, or even relevant, and now the comparison between AI and the foretelling in The Left Hand of Darkness is stuck in my thoughts. There is always a price to pay, and it can be very high.

For LOTS OF REASONS I don’t think it is ever okay for a professor to date a student in their own department. It’s an obvious power imbalance and potentially disastrous for the student’s education and career. So it is real jarring and not fun to see it portrayed as a cute happy romance in a novel!

The working premise of the paper is that the option to submit a preprint before peer review is harmful to early career researchers (again, no evidence presented to support this claim) But this also ignores the way that peer review sometimes functions as *unprofessional* gatekeeping????

Let this sink in. Cornell University refused to refund Jane Doe's tuition the semester she was raped. Without this money, she could not transfer to another school. Essentially, she was forced to stay on campus where she saw those seven rapists frequently. Eventually she dropped out of college.

America's Biggest Problem By me and @valigarmander.bsky.social Read more cartoons! —> #Policartoon Support the cartoons! —>patreon.com/barry
TRANSCRIPT OF CARTOON
This cartoon has four panels. The same bespectacled, bearded man appears in all four.

PANEL 1

The man walks past several masked ICE agents. Two agents are dragging an older man toward the open back of an SUV. Nearby, a distressed woman stands with a small child who is crying. An ICE agent is pointing a gun at the child.

MAN (thought): Hmmm.

PANEL 2

Outside the Supreme Court, several Supreme Court justices in black robes are drinking and celebrating around a bonfire in which the Voting Rights Act is burning. The man walks past in the background, watching them.

MAN (thought): Hmm.

PANEL 3

At a bus stop, a woman is reading a newspaper. The man stands beside her, leaning slightly to read the front page. The newspaper’s main headline says: ANOTHER COMPLETELY UNAUTHORIZED UNNECESSARY WAR

MAN (thought): Mm-hmm.

PANEL 4

We see an open laptop. On its screen, the man is appearing on a TV interview show, grinning as he holds up a copy of his book, Polarization: Both Sides Did It!

MAN: America’s biggest problem is… POLARIZATION!

CHICKEN FAT WATCH
In panel 2, the burning Voting Rights Act is depicted as the “I’m Just a Bill” character from Schoolhouse Rock!

In panel 3, the newspaper is called The Daily Gab. Under the enormous war headline is a much smaller headline: "Study: No one reads smaller headlines or studies." A sub-headline says "'My life is pointless,' says sub-headline writer."

On the wall in panel 3, graffiti includes tags from all eight captains from Star Trek shows (Pike, Kirk, Janeway, Burnham, Freeman, Picard, Sisko, and Archer) plus Taggart from Galaxy Quest. Other graffiti includes “Skitter Lives!” with a spider; a huge "BG," for "background"; and “Never obey! I order U not to obey!” It only occurs to me now, writing this transcript, that I should have made it "not 2 obey." Oh well.

In panel 4, behind the laptop, a large orange cat is sleeping. Curled up asleep on the cat’s tail is a tiny mouse wearing a sleeping cap.

But We Mustn't Ruin HIS Life By me and @postcardsbybecky.bsky.social Read more cartoons! —> #Policartoon Support the cartoons! —>patreon.com/barry
Four-panel cartoon with a tiny kicker panel below.

PANEL 1. A Black delivery worker stands beside her van, holding a package. She looks downcast.

WOMAN: Everywhere I went I was terrified I’d run into **him**. I couldn’t sleep, couldn’t concentrate…  
WOMAN: After I failed two classes I lost my scholarship.

PANEL 2. A girl in pink sits on a bicycle on a residential street, looking down.

GIRL: He sent the video to everyone in school. **Everyone**. I had to be homeschooled until I could get into a different school.

PANEL 3. A woman sits in an apartment armchair, holding a baby who pats her face. She looks sad.

WOMAN: It’s been ten years… My therapist says PTSD isn’t ever cured, but it’s something I can learn to manage.

PANEL 4. A hand holds a phone showing a male podcaster at a microphone.

MAN: Nobody feels worse than me about what happened — but we can’t ruin these young men’s lives!

KICKER. The podcaster speaks with Barry, the cartoonist.

BARRY: What sort of thing would “ruin their lives”?  
MAN: Being expelled. Or being publicly criticized. Or made to switch dorms. Or to switch a class. Basically, anything he might notice.

Black people don't report crimes to the police, especially the NYPD, for reasons that I have shared on here many times. But in the event of a hate crime murder? The victim usually has no choice to not report. Others report the body. And in New York, ~10X more Black people die in hate crime attacks
