A nearby restaurant has the following appetizer on their menu: donuts drizzled with truffle oil, covered in pecorino and parsley, served with marinara sauce. $10.

from news.gallup.com/opinion/poll... nice context for some of the progress the country has made over the last 80-odd years on racial/ethnic prejudice.

From yesterday's exhibits in US v. Sam Bankman-Fried: The prosecution shows that the "insurance fund" that FTX bragged about was fake, and just calculated by multiplying daily trading volume by a random number around 7500
Github diff showing addition of code:

def _get_change()-> Decimal:
    daily_volume = current_session().query(func.sum(Trade.size * Trade.price)).filter(
        Trade.created_at > datetime.now() - timedelta(days=1)).scalar() or Decimal()
        return f2d(numpy.random.normal(7500, 3000))* daily_volume / Decimal('1e9')

@always_run_in_transaction(ro=False)
def update_public_insurance_fund():
    change = _get_change() sess = current_session() +
    public_insurance_fund = Public InsuranceFund.get(sess)

sess.add(Public InsuranceFundChange(public_insurance_fund-public_insurance_fund, size-change))
    public_insurance_fund.size += change
    sess.commit()FTX
@FTX_Official
The 5.25 million FTT we put in our insurance fund in 2019 now makes the fund worth over 100 million USD

I've developed a new forecasting tool! You tell me what your education intervention is, including the full details of how it changes teacher and student behaviors. Then I use advanced AI methods to predict that the effect size is 0.1 SDs. #econsky

Re: recent discussion about Katalin Kariko-- In 2009, Carol Grieder won the Nobel Prize for her work on telomeres. That same day, she got a notification that her NIH grant proposal was deemed not worthy of discussion due to "limited preliminary data."

Much progress is really just realizing existing rules were just dreamed up and aren't at all necessary.

Crowdsourcing ideas for a document of "solved problems worth solving". Structure: - Here is a problem and the real consequences - Other places have had the problem and solved it. - If 5-10 people spent a decade on it, they could prob solve it here.

Very cool— fit multivariate state space models with stationarity of the state process enforced by the Heaps prior. Potentially helpful to many of you. nicholasjclark.github.io/mvgam/articl...

I want to see a show like Alone but called “Together”. Groups have to form and survive in small tribes, allocating roles and dividing labor, creating lore, egging each other on. And fighting moose.

Summers Corollary: it takes as much effort to think about a policy reform that changes the world as changes academia; and only one of those matters; so you might as well focus on the world

Adjusting for hours spent driving, do taxi drivers have more or fewer accidents than other drivers?

Has the number of bits of information you need about the shape of a car to distinguish its make and model increased over time? As in, have cars become more similar?

Huh. Lyft’s market cap is 1/25th of Uber’s. Hadn’t been following and this is surprising.

I find myself repeating @yashkaf.bsky.social ‘s advice to singles (useful for non-singles too): try finding reasons to like other people rather than finding reasons not to like them.

A challenge in Data Science: data scientists who know how to avoid all the traps of bad analysis suck at building scalable tools. And visa versa. Prediction: AI assistants seem to be better suited to helping researchers do software engineering than helping software engineers become researchers
