Yoel Roth, the former Head of Trust and Safety for Twitter, shared his thoughts on Musk’s handling of Twitter and the reasons for his departure while speaking at a Knight Foundation conference. He largely just confirms what we all know from following the debacle, though he does demonstrate a good practice for personal and professional life– defining clear boundaries:

“Before Musk took over Twitter, Roth wrote down several commitments to himself that would trigger the decision to quit. One limit, he said — one that was never reached — was that Roth would refuse to lie for Musk. Another limit, one that was ultimately reached and drove his decision to resign, was ‘if Twitter starts being ruled by dictatorial edict rather than by a policy.’”

I’ve recently released gpu-io – a #webgl computing library for real-time physics simulations, particle/agent-based systems, cellular automata, image processing, and general purpose GPU computations.

Examples: apps.amandaghassaei.com/gpu-io
GitHub: github.com/amandaghassaei/gpu-

gpu-io makes it easy to build GPU-accelerated apps without worrying about low-level WebGL details and browser inconsistencies. Designed for WebGL2 with fallbacks for WebGL1. WebGPU support is planned! More in thread 🧵...

This visualization attempts to represent Elon Musk’s extreme wealth, and it is frankly obscene.

An examination of over 1 million funding proposals to the National Science Foundation from 1996 to 2019 reveals that white principal investigators are consistently funded at higher rates than most non-white PIs and relative funding rates for white PIs have been increasing. elifesciences.org/articles/830

Physicists have used Google's quantum computer to send a signal through a wormhole, a shortcut in space-time first theorized by Einstein and Rosen in 1935. The landmark experiment was published today in Nature. Lots to say about it. Here's my very deep dive: quantamagazine.org/physicists-

HISTORY! The Senate has passed the Respect for Marriage Act granting federal recognition to same-sex marriages by a vote of 61-36. Only 12 Republicans joined every Democrat in voting for the landmark bill.

There is always a fancy new way to use statistics to reinvent phrenology. :P

One of the great pleasures of my regular park walks is running into wildlife like this barred owl. The photo looks a bit painterly because I had to zoom in on a low-quality camera phone.

“[The] Gross National Product counts air pollution and cigarette advertising, and ambulances to clear our highways of carnage. It counts special locks for our doors and the jails for the people who break them. It counts the destruction of the redwood and the loss of our natural wonder in chaotic sprawl. It counts napalm and counts nuclear warheads and armored cars for the police to fight the riots in our cities… Yet the gross national product does not allow for the health of our children, the quality of their education or the joy of their play. It does not include the beauty of our poetry or the strength of our marriages, the intelligence of our public debate or the integrity of our public officials. It measures neither our wit nor our courage, neither our wisdom nor our learning, neither our compassion nor our devotion to our country, it measures everything in short, except that which makes life worthwhile. And it can tell us everything about America except why we are proud that we are Americans.”

As John Tyler Bonner, a professor of ecology put it, slime molds are “no more than a bag of amoebae encased in a thin slime sheath, yet they manage to have various behaviors that are equal to those of animals who possess muscles and nerves with ganglia – that is, simple brains.”

Slime molds are fascinating. They can live as single-celled organisms or work together as a colony that differentiates functions and exhibits learning behaviors without having anything like a brain. Training one slime mold and then allowing it to fuse with another transmits the training with the new slime mold.

Untitled Ode to Scientific Wonder, by Richard Feynman 

I stand at the seashore, alone, and start to think.

There are the rushing waves
mountains of molecules
each stupidly minding its own business
trillions apart
yet forming white surf in unison.

Ages on ages
before any eyes could see
year after year
thunderously pounding the shore as now.
For whom, for what?
On a dead planet
with no life to entertain.

Never at rest
tortured by energy
wasted prodigiously by the sun
poured into space.
A mite makes the sea roar.

Deep in the sea
all molecules repeat
the patterns of one another
till complex new ones are formed.
They make others like themselves
and a new dance starts.

Growing in size and complexity
living things
masses of atoms
DNA, protein
dancing a pattern ever more intricate.

Out of the cradle
onto dry land
here it is
standing:
atoms with consciousness;
matter with curiosity.

Stands at the sea,
wonders at wondering: I
a universe of atoms
an atom in the universe.

"The brain uses calculus" is a bit cringe, but the article is interesting. The timing of excitation and inhibition changes can enable a derivative-like process.

By coincidence, two articles recently came to my attention on the dangers of the use of storytelling, one in the public realm and the other in the private. Both have given me a good deal to think about. 

The first is a reflection on Seduced by Story: the Use and Abuse of Narrative by Peter Brooks. Brooks argues, in short:

“[W]e’ve relied too heavily on storytelling conventions to understand the world around us, which has resulted in a “narrative takeover of reality” that affects nearly every form of communication—including the way doctors interact with patients, how financial reports are written, and the branding that corporations use to present themselves to consumers. Meanwhile, other modes of expression, interpretation, and comprehension, such as analysis and argument, have fallen to the wayside.”

The second, Don’t Treat Your Life as a Project, challenges the value of compressing your life (and self-concept) into a story:

“Projects fail and people fail in them. But we have come to speak as if a person can be a failure—as though failure were an identity, not an event. When you define your life by way of a single enterprise, a narrative arc, its outcome will come to define you…. What makes the narrator’s life worth living is not some grand narrative, running from conception or birth to inevitable death; it is the countless little thoughts and deeds and gentle, joking interactions that occupy day after day after day. If you pay attention… there’s enough in a single lunch hour to fill a book.”

Hello all,
Please boost this toot to spread it around.
The link is to a formal logic textbook which I have been compiling and expanding. I have been the only one editing/fact-checking it, so I would love to have other eyes look it over or even play-test it in the classroom. It also has an OER and open-source course companion, Carnap.io, if you would like to use that.

Great review of #QuadraticVoting systems, which let voters express what they want *and* how much they want it. Each gets a certain number of points to allocate among, say, a set of issues. They can give more to their top picks, but that’ll leave them fewer for others. Each extra point brings diminishing returns (the “quadratic” part). So the system discourages extreme positions. economist.com/christmas-specia
