It is thus that ignorant prejudices are fostered ;
and how few of us in afterlife have the time or the will
to sift the rubbish of the dust-bin of history
on the chance of discovering the diamond of truth.

the boxes full of papers and odds and ends he carted around with him
almost everywhere as the "beautiful mind" material. It was a reference to
the title of a book and movie depicting the life of John F. Nash Jr., the
mathematician with schizophrenia played in the film by Russell Crowe,
who covered his office with newspaper clippings, believing they held

ABSTRACT Determining the affine equivalence of Boolean functions
has significant applications in circuit and cryptography.
Previous methods for determining this require a large
amount of computation when Boolean functions are bent
functions or when the truth table is sparse. This paper
presents a new method to determine the affine equivalence
based on matrix algebra. By transforming Boolean function
to the corresponding matrix representation, we first propose
and prove the congruent standard form of Boolean function.
It lays the foundation for the determination of equivalence
because affine Boolean functions must have the same
standard form. Then we find the generators of orthogonal
matrix group and symplectic matrix group, which greatly
reduce the search space. The computation complexity of
our method is o (2r2/2+n∗(n−r) ), where n is the number of
bit operations, and r is the rank of the matrix, which is
the product of Boolean-1 matrix of the test Boolean function
and its transposition. The experimental results show that our
method is useful when the test Boolean function is no more
than 7 bits and r is greater than 2.
In memory of Cormac McCarthy, who reportedly
died today, here is a phrase by John Jeremiah Sullivan
in a NY Times review of McCarthy's 2022 novel The Passenger —
"a reminder (just in time) of the elegance and force
of good McCarthy."
Sullivan also writes well. For instance, see the "pretty horses" of this post's title.
"If it’s possible to be two things at once,
I was both pathologically insecure and
intoxicated by the power that my newly

to have conferred on me."
Tom Wolfe on art theorists in The Painted Word (1975) :
"It is important to repeat that Greenberg and Rosenberg
did not create their theories in a vacuum or simply turn up
with them one day like tablets brought down from atop
Green Mountain or Red Mountain (as B. H. Friedman once
called the two men). As tout le monde understood, they
were not only theories but … hot news,
straight from the studios, from the scene."
"The album cover was a minor but deliriously popular art form
that was limited not just by shape—a neat fit, incidentally, for
the square format favored by many modish photographers of
the sixties—but also by the prospect of its own inevitable death.
Technology gave, and technology hath taken away."

“The kind of movement Olson urges is an inward deepening of the image,
an in-sighting of the superimposed levels of significance within it.
This is the very mode that Jung suggested for grasping dreams —
not as a sequence in time, but as revolving around a nodal complex.”

"In The Electric Kool-Aid Acid Test , Tom Wolfe writes about encountering
'a young psychologist,' 'Clifton Fadiman’s nephew, it turned out,' in the
waiting room of the San Mateo County jail. Fadiman and his wife were
'happily stuffing three I-Ching coins into some interminable dense volume*
of Oriental mysticism' that they planned to give Ken Kesey, the Prankster-
in-Chief whom the FBI had just nabbed after eight months on the lam.
Wolfe had been granted an interview with Kesey, and they wanted him to
tell their friend about the hidden coins. During this difficult time, they
explained, Kesey needed oracular advice."

CHICAGO–(BUSINESS WIRE) — It is with profound sadness
that Equity Residential (NYSE: EQR) mourns the death of its
Founder and Chairman, Samuel Zell, who died today at age 81.
Sam Zell, the Chicago real-estate magnate whose knack for buying up distressed assets turned him into a billionaire and earned him the nickname “grave dancer,” died on Thursday, his company said. He was 81.
Equity Residential, the company he founded decades ago, did not provide a cause of death but described Zell as an “iconic figure in real estate and throughout the corporate world.”
Among his wide-ranging portfolio of investments were distressed assets in real estate and in media, including an ultimately disastrous bet on the Tribune Company. Zell had a personal net worth of $5.9 billion, according to the Bloomberg Billionaires Index.
Zell had a penchant for scooping up cheap real estate and selling it later at a profit, a strategy he outlined in a 1978 article titled “The Grave Dancer,” which became his nickname in the industry.
“I was dancing on the skeletons of other people’s mistakes,” he wrote.
"Speaking of artificial intelligence, it seems as if the creators of 'Mrs. Davis' have ironically chosen to utilize A.I. in the show's production. During a panel at the film festival South by Southwest, Lindelof mentioned how they used artificial intelligence and said, 'We thought it would be fun to build an A.I. that would title our episodes, and that we just basically said that whatever it comes up with, we have to stick to as long as it is appropriate for whatever barometers of appropriateness exist.'
Damon Lindelof continued and explained that in the process of creating the A.I. that would title episodes for the upcoming 'Mrs. Davis,' the artificial intelligence struggled to understand what a title actually was, despite the information that was filtered through the program. Lindelof then said that the entire production crew learned a great deal about algorithms and how A.I. works while attempting to get it to generate episode titles. In the end, Lindelof and the rest of the crew were quite happy with the results, noting that Episode 7 is titled 'Great Gatsby: 2001: A Space Odyssey.' "
