This may just be the best CS paper I’ve read this year. Just read the abstract and first para of the intro! The rest of the intro is really wild too, but very very good:

dl.acm.org/doi/pdf/10.1...
A screenshot of an academic paper. It reads:

Abstract
A "
'quine" is a deterministic program that prints itself. In this essay, I will show you a "gauguine": a probabilistic program that infers itself. A gauguine is repeatedly asked to guess its own source code. Initially, its chances of guessing correctly are of course minuscule. But as the gauguine observes more and more of its own previous guesses, it detects patterns of behavior and gains information about its inner workings.
This information allows it to bootstrap self-knowledge, and ultimately discover its own source code. We will discuss how-and why-we might write a gauguine, and what we stand to learn by constructing one.
CCS Concepts: • Computing methodologies → Philo-sophical/theoretical foundations of artificial intelli-gence; Theory of mind.
Keywords: reflection, probabilistic programming

1 A Way of Knowing

From time to time, we all have crises of identity-moments of radical and overwhelming uncertainty about our selves.
I' don't know whether the doubts that seize us can really be externalized in language, but if I were to try, I would express them as questions, questions like: Who am I? What am I?
What kind of person? What kind of mind?

NHANES is an invaluable tool that many researchers including myself use to report on conditions in the general population.

Like the fact that ~40% of 12-21yo females are iron deficient.

And so much more important work.

But they’re destroying it all.

Rapid RL experimentation is great. But how do you catch silent errors before they slip by?

In this post, I share tools and habits that help me move quickly from idea to result without sacrificing reliability.

I don't know! For my class I'm subtweeting (word problems for poets and quants) probably we need to split into ai vegan & totally vibe-coded project based learning. But more broadly - relying just on in person exams as wake up calls (our current strat) sounds miserable for everyone.

Smart! How long does it take to do the quiz?

More constant but lower-stakes formative assessments. My course has short (3 q) pass/fail, multiple choice, in-person quizzes every week. But students can retake (another version of) them some weeks later to get the credit back upon fail.

Hey teaching folks are you seeing this trend to:
- anything submitted online is fair game for AI usage and quizzes online might as well be hws (aka ai)
- only in person exams will get folks to look at course materials-> 4 midterms in a course
- too many midterms -> always overwhelmed -> use AI

Last week, convention center expert Heywood Sanders wrote this about LA's expansion plan: "the likelihood of any significant increase in the city’s convention business is effectively nil."

So I called him up to talk me through his analysis — and what he told me makes LA's plan seem *even worse*
Why this convention center expert is calling LA's expansion plan a disaster
"If you think that somehow a bigger convention center is key to downtown revitalization, or is going to do wonders for local job creation, or economic development? The answer is, you've got to be kidd...

As someone currently on probation at Princeton, what also stands out here is the sham faculty governance on display:

Faculty panel reviews all the evidence n decides there is no grounds for suspension.

Admin overrules their decision n Provost Kavita Bala calls for significant disciplinary action.

The opportunities and risks of the entry of LLMs into mathematical research in one screenshot. I think it is clear that LLMs will make trained researchers more effective. But they will also lead to a flood of bad/wrong papers, and I'm not sure we have the tools to deal with this.

Everyone, I wanted to let you know about the sad news that despite everyone's best efforts Bluestockings will close at the end of the year: www.bluestockings.com - I want to thank every single person who sent books to them through my book drive [will share more later]. A tremendous loss to NYC.
