“James would have documents typed, annotate them, and then dispatch them to comrades around the world for political discussion and feedback.”
I ran out of characters but her name is Selma James.
“Have the letters typed” like the typists and their don’t matter. In a Marxist discussion. Good god.
Anyway you can see in this milieu of watching her husband be vaunted as a theorist while she was his main intellectual partner and making his work possible while also not being acknowledged that she first formulated the need for a Wages for Housework campaign.

I’m so annoyed!!

\u201cHave the letters typed\u201d like the typists and their don\u2019t matter. In a Marxist discussion. Good god.
“But he wrote the Black Jacobins when she was still a kid” yes but as the interview notes, he came back to it for multiple editions and *someone* was typing his documents
Selma James was the someone. The typist had a name, a life, and an intellect of her own.
We got texts between the organizers of the Jan. 6, which the Trump campaign says they definitely, absolutely didn\u2019t organize.

\u201cGet the budget and vendors breakdown to me,\u201d wrote a long-time Trump fundraising officialhttps://t.co/ScyGTGz8Mp

"On Dec. 29, after receiving the budget, Wren instructed Chafian... to hold off on printing event-related slogans “until we decide what the messaging is and we have no clue on timing because it all depends on the votes that day so we won’t know timing for a few more days.”
"The “timing” appears to be a reference to Congress’ Jan. 6 vote to certify the election results." Well that's going to get some attention by law enforcement
"Chafian told ProPublica that she herself had been directed by [Alex] Jones to Wren, who, she was told, had ties to a wealthy donor who wanted to support the January affair. Chafian said the donor is a woman but wouldn’t disclose her name, citing a confidentiality agreement."
"A guidance memo provided to VIP attendees of the Jan. 6 rally further establishes Wren’s centrality to the event. She is listed, along with three other people, as one of the primary points of contact for the demonstration."
We all did this as kids: Walk up a see-saw, you keep going fine until you cross the fulcrum then WHAM! It flips.This is what happens in nature when resources are used up faster than they are replenished. All goes fine until nearly half are used up. All who study biology know..2/
This flip is a population crash. It is natural. Important to know: the crash comes after the point where more resources are being used up than are being replenished. There is a period of overshoot. The crash comes some time after overshoot. Can that happen to humans? 3/
According to Joseph Tainter (1988) there have been three:
Ancient Rome
Mayan Civilisation
Ancestral Puebloans

All of this is well-known by scholars. But somehow it does not seem to have sunk in with citizens in general. The urgency. So let me say it again in a retweet-worthy way 5/
Stop asking a girl if she has a boyfriend(no ring means AVAILABLE) . Take her out on different dates, give her ATTENTION, treat her nice, make her laugh and above all be honest with her and make her feel safe with you... Then, let her decide if she's single or not \U0001f60e

A few people in the DMs asking about equity factor models so here's a short explainer.

Let's make it a concrete problem -- you are the risk manager at a big multi-manager hedge fund with ~100 sub-PMs each of whom has a portfolio of 10-50 stocks, long and short.
1. How do you get the exposure matrix Xt?
There are different ways to estimate it, depending on the factor. Simplest is factors like industry or country exposure where the entries can be 0/1 depending on whether the stock is in that industry/country or not.
Some exposures can be estimated by linear regression on historical data, if you already have a time series which approximates the factor returns. E.g. exposure to the market factor (beta) is estimated this way, by regressing each stock against the S&P 500 (or some other index)
This also works for "macro" factors e.g. you can estimate exposures for each stock to commodity prices, exchange rates, interest rates, GDP or inflation surprises etc by regressing stock returns against the relevant historical time series.
Finally you can have exposures which are heuristically derived from other observable data about the stock, e.g. accounting data, analyst reports, past price movements etc. In this case you find some metric which measures the factor you care about (e.g. price to earnings) and
