In Nixon v. Fitzgerald¹, the Supreme Court wrote “While the separation of powers doctrine does not bar every exercise of jurisdiction over the President, a court, before exercising jurisdiction, must balance the constitutional weight of the interest to be served against the dangers of intrusion on the authority and functions of the Executive Branch.”

The current court cited that thusly in Trump v United States²:

"At a minimum, the President must be immune from prosecution for an official act unless the Government can show that applying a criminal prohibition to that act would pose no ‘dangers of intrusion on the authority and functions of the Executive Branch’.”

Fitzgerald described a balancing test between the public interest and the dangers of intrusion. Trump truncated the quote to turn it into a prohibition.

This Court is purely outcome-driven. In my mind, that makes it illegitimate. We might try returning to the original Constitutional order, in which it was recognized that all

1. The study looks at how the use of a faked “AI assistant” affects the judgment of radiologists evaluating mammograms with a suspicious lesion, rating on a scale with these values: 2 -> benign; 3 -> probably benign; 4 -> suspicious; 5 -> highly suggestive of malignancy.

2. They extracted a set of 50 mammograms from a big archive. Either those mammograms had already been scored, or they had an experienced radiologist score them afresh (not sure which). I'm going to call this the pre-experiment score. In either case, the appropriateness of the score was confirmed. It's not clear, but I think it went like this: For "suspicious" and "highly suggestive", they only included mammograms for which a biopsy actually found a malignancy; for "benign" and "probably benign"; they only included mammograms if four years had since passed without otherwise discovering a problem.

3. The participants were shown the image, an AI score, and asked to produce

A rant in re: Illinois v. Caballes

Facts

1. Dude is transferring 250,000 dollars of marijuana in the trunk of his car.
2. He’s stopped for going six miles over the speed limit(!¹)
3. When the stopping officer calls it in, another officer overhears it and offers to bring by his drug-sniffing dog and give it a spin. The dog alerts, the trunk is opened (without Caballes' consent), and the drugs are found.

It’s notoriously hard to identify the boundaries of fascism¹, but the following quote strikes me as capturing something important:

Now it is not enough to learn how to shoot. In the name of historical justice, in the name of life’s instinct, in the name of truth—we must shoot.²

Self-actualization through violence.

I’m fond of Edith Hamilton’s summary of the classical Greeks' definition of happiness:

The exercise of vital powers, along lines of excellence, in a life affording them scope.

The brain does not like to work. It's a lot of work to have a true picture of the world live inside the brain. So the brain doesn't do that as much as you (it) thinks.

Some of the ways the brain avoids work may give help to people who show computers how to do the work computers do. Here are the ways I will talk about:

• Have lots of little boxes of work. Each box looks for just one thing and knows how to do just one thing. It knows just enough to see the one thing and make the thing it knows how to do happen.

• Many boxes are looking at the same time. The brain is always ready to do something else.

• If two boxes both know the same thing or two, you can make another box to hold what's shared. But you only do that if it makes there be less work. Do that enough and you may get a true picture of part of the world. But most of the time you don't.

For a very long time, large structures were made of masonry: brick and stone and concrete. Masonry is strong when you’re squeezing it (putting it under compression). It is not strong under when it’s being pulled (placed under tension). This is a problem for building roofs. Consider a horizontal beam made out of masonry. Gravity is pulling down on the whole beam, but the ends are supported. So the tendency would be for the middle to droop down – which puts the masonry under tension.

The arch is the one weird trick to solve that problem. The shape of the arch means the higher bricks (say) push on the lower bricks – which is the kind of compression bricks can take. At the legs of the arch, all that weight producews a force pushing down and to the side. If the arch is fastened to the something big, like the earth, that force won’t have an effect, because the earth can push back just as hard.

The roof of a cathedral is essentially a bunch of arches resting on walls. Those walls have to resist the downward force

For linsen:

1. Rinse 1 bag lentils. Cover lentils with water in pot and boil for 30 minutes. Add water if needed.
2. Cook several strips of bacon. Save a little of the grease. Put bacon on paper towels until cooled, then crumble it.
3. Chop 1 onion and cook it in the bacon grease. Add a Tablespoon or so of flour, stir it in and cook about 30 seconds.
4. Add onions and bacon to the lentils.
5. Cut up 1 lb of hot dogs and add to pot. (This is excessive, but some hot dogs are traditional.)
6. Add about 1 Tablespoon of salt, a capful of white vinegar, and about a half teaspoon of pepper.
7. Cook til correct consistency. (Mushy)

I see tweets like this:

 "The coronavirus outbreak has me thinking back to when I was a server 
 and worked a week straight while I was really sick and it turns out I had 
 the swine flu and was probably spreading it to everyone because I couldn’t 
 take off work and I’m sure that will happen with this"

I'd like to somehow help out people for whom medical care is too expensive, who don't get paid sick leave, who might get fired if they don't tough it out:

• You’ve talked a lot in the past about releasing regularly and constantly having a shippable product. At the same time, companies like Google and Facebook have the “single branch” approach where everyone commits to the master branch, so anyone can break anything at any given time. When you’re operating at the scale of these companies, with thousands of developers, do you think the approach of continuous deployment to one branch is flawed?

• You mentioned in your lightning talk about being naive in the face of expertise that you had assumed it was an immutable fact that developers would never like writing tests. As students, much of our work is graded by an autograder where other people take the time to write the tests, and we generally only have to worry about writing the code. Do you think teaching computer science in this way reinforces the idea that developers should not be worrying about testing? And how do you think CS education should change to adapt a test-first approach?

• I know that Agile scrum
