An immigration court dropped its case against Turkish graduate student Rumeysa Ozturk, a little less than a year after federal agents arrested her on a street near Tufts University

While we're all watching one too many AI ads, I just finished grading 60 student essays. Hard to tell for sure, of course, but somewhere between ½ and ¾ must have been fully AI generated.

The AI check (shown to students at time of submission), and another Claude check agree.

100% detected as AI

The percentage indicates the combined amount of likely AI-generated text as well as likely AI-generated text that was also likely AI-paraphrased.

AI-generated text that was AI-paraphrased
0 instances of likely AI-generated that was AI-Paraphrased making up 0% of the submission
Likely AI-generated text that was likely revised using an AI-paraphrase tool or word spinner.

AI-generated?

Yes, this appears to be AI-generated.
Key indicators:
Structural formulae: Every paragraph follows the same pattern: observation → acknowledgment of merit → diplomatic suggestion for improvement. This mechanical consistency is characteristic of AI.
Hedging language saturation: "could be strengthened," "would benefit from," "merits more direct engagement" - the relentless diplomatic cushioning lacks the directness typical of human reviewers.
Tonal uniformity: No variation in energy, specificity, or critical edge across the entire piece. Human reviewers typically show more range - getting more engaged with strong points, more frustrated with weak ones.
Vocabulary deployment: Sophisticated terms used with perfect consistency ("framing device," "probabilistic reasoning," "gestures at breadth") but without the idiosyncratic phrasings that mark individual voice.

One of the more ambitious projections for Voluntary Carbon Credits I've seen of late: ~$50b by 2035, up from ~$1.5b today.

Quick sanity check: Today's size of Europe's (compliance) market alone? ~$200b.¹

California's? ~$10b.²

Hey @zohrankmamdani.bsky.social, minor request but one of these 'nudges' with outsized influence:

@nyc311.bsky.social alerts have a near daily parking reminder. 90% of New Yorkers don't need that.

Ask drivers to sign up for some special alerts only they need.

Send flower emojis to the rest of us.

Anstatt dessen lernt er jetzt Chinesisch. "Anwendbarer"? Wahrscheinlich. Aber am Ende geht's um das Lernen selbst. Jede Sprache ist "nur" Mittel zum Zweck.

The thing, of course, is that some of these people will get through the nomination process, where they'll do damage for decades to come.

I am running out of ways to convey how disconnected from reality Trump's judicial nominees are. They can't say that Trump lost the 2020 election, they won't say that the January 6 insurrection happened, they don't acknowledge any fact about anything if Trump hasn't authorized them to believe it

Trump Is Building a Federal Judiciary of Delusional, Cowardly Loyalists

Judges have to decide cases based on facts. For Trump judges, the only facts that matter are the ones that he authorizes them to believe.

Each and every day, we’re committed to providing accessible and equitable transit for all.
