• Cincinnatus’ name means “curly-haired”.

• The namesake of the chlamydia infection (and also the less well-known Chlamys, a bivalve mollusc) is the Chlamys, a short cloak worn by the ancient Greeks, and most notably Hermes.

• You should never go swimming with a kangaroo; it will attempt to drown you.

• Dr. Spock ran for president in 1972 against Richard Nixon and George McGovern. He received around 0.1% of the vote.

• McGovern, the losing major-party candidate, was utterly flattened by Nixon, who won over 60% of the popular vote and 520/538 electoral votes. Nixon, of course, resigned in disgrace in August 1974.

Today the School District of Philadelphia informs me:

All children are capable of reaching their fullest potential

This reminds me a little of the time I had to explain to someone on Math Stack Exchange why every function is onto its range.

And by “the Michigan Supreme Court” I meant “the Wisconsin Supreme Court”.

• Six of the seven justices of the Michigan Supreme Court are women.

• Catalonian nativity scenes traditionally include El Caganer, a figure of a guy pooping with his pants down.

• Another Catalonian Christmas tradition is Tió de Nadal, the Christmast Log. This is a small log with a happy face and a red hat, propped up on legs. In the run-up to Christmas, the kids feed the log daily, and then on Christmas Day it magically poops out nougats, hazelnuts, or other plausible log poop objects such as dried figs.

• To make Tió de Nadal defecate, one puts its end into the fireplace, or, if no fireplace is available, beats it with sticks.

• Tió (“trunk”) should not be confused with tío (“uncle”).

Q: What do you call a centipede after you've stepped on it?

A: A nillipede.

Ms. 16 drove me to Valley Forge today. Perhaps you have heard that Washington was grievously injured at Valley Forge. He was struck by a small cannon ball, and his skull was fractured in three places.

On Saturday when I woke up Lorrie said I had awakened her in the night, and asked me what I had been saying. It had woken me up too, and I remembered.

I had been dreaming that I was at some sort of a conference, and at the start of a conference session, everyone in the audience stood up, put their hands on their hearts, and sand The Star-Spangled Banner.

In the dream, I sang also, and when the song ended, I shouted “PLAY BALL!”

Python code I wrote today:

Larry Wall says that a successful program is one that does its job before your boss fires you. Somehow I don't imagine Guido being as lenient.

• Brian Ritchie, bassist for the Violent Femmes, is also proficient at playing the Shakuhachi (Japanese bamboo flute) and has released two albums of Shakuhahi music.

• In 1996 the Femmes and the Red Hot Chili Peppers played a promotional concert at the magnetic north pole.

Suppose you have available an evil necromantic spell that turns humans into mindless zombies. (Whether the humans are required to be dead or alive is not important for this inquiry.)

What happens if you cast this spell on starfish instead, turning them into mindless zombie starfish?

Today I had a cream cheese and cashew nut sandwich. It was pretty good.

It was inspired by the “nutted cheese” sandwich found at Chock full o'Nuts lunch counters long ago. (Theirs had walnuts, not cashews, and was served on dark raisin bread. When I have the ingredients handy I sometimes make the walnut and raisin bread version, which I recommend.)

These days Chock full o'Nuts exists primarily as a supermarket coffee brand. I'm so old I can remember actually eating a chicken salad sandwich at one of the lunch counters.

Thinking on this a little more, I think you have to make Ringo d'Artagnan, and play up his country-bumpkin-ness.

Then George is Aramis (obviously) and Paul is Athos, so that makes John Porthos.

According to Wikipedia:

[The Three Musketeers] was originally proposed in the 1960s as a vehicle for The Beatles, whom Lester had directed in two other films.

I am having a lot of trouble picturing this. Which Beatle is which Musketeer? There is no Porthos in the Beatles. There is no Ringo in the Musketeers.

The script was written by George MacDonald Fraser, creator of Harry Flashman.

I would watch a Flashman movie. The likelihood of there being a Flashman movie for me to watch, in the next twenty or thirty years, seems close to zero.

Aha, but there is already a Flashman movie, directed by the same Richard Lester who directed The Three Musketeers. Malcolm McDowell plays Flashy. And Oliver Reed, who played Porthos, returns in Royal Flash as Otto von Bismarck. How about that?

Etsy search for “not a place of honor” produces nothing relevant. This is a hundred-dollar-bill on the sidewalk, waiting to be picked up.

I want it on a doormat.

• The western blot was named as a joke. There was already a Southern blot test that was named after its inventor, Edwin Southern.

Though rarely seen, the Siberian Snow Camel is a majestic beast, with its splayed hooves and shaggy white fur. Modern populations of Snow Camels are believed to be remnants of the great herds that crossed the land bridge during the last ice age and whose descendants evolved into the bison of the North American plains.

This video is an unboxing of a 20,000-watt incandescent light bulb. (“It doesn't have a filament in it, it has eight garage door springs.”) My question: why was this bulb manufactured in the first place? What are the applications?

If you need that much light, even before LEDs, you would probably use mercury-vapor or metal halide lamps, which draw much less power and probably lasted a lot longer. So what's this for?

Also, I remember seeing in a museum an even larger incandescent bulb, touted as the largest ever made. Maybe at the Chicago Museum of Science and Industry? Does this ring a bell for anyone else?

Twitter says they're going to encourage their programmers to replace the term “dummy value” with “placeholder value” and now I can hardly wait for the chance to refer to someone as a “placeholder value”.

• Kola nuts are native to Africa, not South America.

A colleague asked me to provide “choice quotes” from Thomas's dissent, which I said “might be the most Clarence Thomasy thing I've ever read”. But I think they were disappointed, because what makes it so very Clarence Thomasy is how dry and fussy it is. Here's a choice quote, if you can call it that, which examplifies what I had in mind:

The Oklahoma Court of Criminal Appeals concluded that petitioner’s claim was procedurally barred under state law because it was “not raised previously on direct appeal” and thus was “waived for further review.” This state procedural bar was applied independent of any federal law, and it is adequate to support the decision below. We therefore lack jurisdiction to disturb the state court’s judgment.

Maybe I should write a longer article on the real blog explaining what this means. I wouldn't have to worry that doing so would kill the joke, because there is no joke and there was nothing funny to begin with.

Am I the only person who imagines that Clarence Thomas is severely constipated, like, almost all the time?

I thought that the recent McGirt decision would have some connection with _Sherrill v. Oneida Nation, but no, there is no mention of it whatever. I must be seriously confused about something, can anyone tell me what?

On review, I see that it did come up briefly in oral argument:

Sherrill is always in the room when the states and the tribes are negotiating agreements

so I'm not completely confused.

I would like to understand this better.

Finite sets are always compact. Suppose we have an infinite compact space. Is it possible that the only compact proper subspaces that it possesses are the finite ones? The answer turns out to be no. Every infinite compact space has an infinite compact proper subspace. So by repetition, every infinite compact space has an infinite descending chain of compact subspaces.

I thought hey, here we have a partial order (of infinite compact subspaces) in which every descending chain has a lower bound, so we can apply Zorn's lemma… except no, not every chain has a lower bound, what was I thinking? If we include the finite subspaces then every chain does have a lower bound and we can apply Zorn's lemma, but the result is the empty subspace so that was not useful.

Interesting: The example of !![0,1]!! shows that you can't always obtain a smaller compact subspace by deleting a finite set from the original space.

The compact subspaces of an infinite compact set form a rather interesting lattice structure. At the bottom are the finite subsets, arranged like a very ordinary Boolean lattice, but with no maximum element. (Isn't there a name for a complete associative lattice that may or may not have a maximum element?) Floating above this are the infinite compact subspaces, in which there are no minimal elements, and the original space at the top.

Consider just a relatively simple example. Let !!X!! be the one-point compactification of the natural numbers. That is, $$X = \Bbb N \cup {\infty}$$ where a subset !!G!! of !!X!! is open if and only if !!G!! is a finite set that does not contain !!∞!! or !!G!! is a cofinite set that does contain !!∞!!. An infinite compact subspace of !!X!! must contain !!∞!!.

Clarence Thomas's dissent in McGirt might be the most Clarence Thomasy thing I've ever read.

• Spanish for “tumbleweed” is “la rodadora”.

• There is a really cool-sounding museum in Ciudad Juárez called La Rodadora espacio interactivo (Tumbleweed interactive space). New place on my should-visit list!

Montana is the U.S. version of Inner Mongolia.

The last thing I remember from my dreams this morning is someone informing me, very authoritatively, that there are three things that Alexander the Great really wants.

I don't remember the first two but the third was bow-tie pasta.

Today I learned that Reddit has an r/notinteresting forum.

Amused, I checked into it, and was disappointed to discover that it was not interesting.

Disappointed?

It's kinda funny that we still have “happen”, “happy”, “mishap”, “hapless”, “haphazard”, and so on, but the original word “hap” is completely gone.

“Pissburgh”.

I did this twice.

I am so, so sorry.

It turns out that the file I was given already had sequences for Ő and ő, but only with the <equal> before the letter, not after, which meant that 50% of the time I couldn't find it.

Following Tony Finch's suggestion I have been using ⸢ and ⸣ (square quotes) as scare quotes.

I sometimes think about adding sequences for Greek letters other than π and ε, but it's really not the right place to solve the problem.

My computer environment came equipped with a giant .XCompose file full of useful abbreviations, many of which I use frequently. It is much easier to commit to spelling ‘Sierpiński’ correctly when there is an easy and natural way to type the ‘ń’.

But some things were missing, and I have gradually added them over the years. Today I discovered that while it predefined sequences for þ and ð, it had none for ȝ. (This makes sense, as þ and ð are still used in modern Icelandic, and even appear in ISO 8859-1, whereas ȝ is obsolete.)

Early on I had to add a sequence for ‘ő’ so that I wouldn't have to misspell “Erdős”. You can see where my priorities are.

“Kennel” is (ultimately) from Latin canis.

I went searching for Thomas Caxton and instead I typed “caaxtron”.

ALL TREMBLE IN FEAR BEFORE CAAXTRON 9000 THE INVINCIBLE, PRINTER OF WORLDS

Trump is talking about using tanks to quell the George Floyd protests, but the Pentagon is getting cold feet:

As of Monday morning, 17,000 National Guard troops had been deployed in 23 states and Washington, DC. No state has requested federal assistance, however, subverting the normal process for domestic military intervention, Pentagon officials told The Beast.

I can't get over the word “subverting” there. What do the unnamed Pentagon officials think the “normal process” is, or should be?

I think Richard nixon would have looked better with a mullet.

People sometimes say that “there are no stupid questions”. I disagree.

If the question admits only stupid answers, I think that's pretty strong evidence that it was a stupid question.

A hapless loser on Math Stack Exchange asks:

What is the minimum number of people in a single room so that it can be said “There are two people in this room with birthday in January ”?

Possible answers include:

1. There is no minimum, because the room might contain any number of people, all of whom were born in November, and no others.

2. The minimum is 2, if both were born in January.

3. The minimum is 0, because you can say whatever you like, regardless of who is in the room.

One often hears the factoid that

In a year, the averge person swallows eight spiders in their sleep.

Of course, this is nonsense. The correct statistic is eight spiders per minute.

Today Twitter has drawn my attention to #คั่นกูEP11, which they claim has appeared in 496,000 tweets. This seems to concern episode 11 of a Thai TV series I hadn't heard of before.

I like these Twitter trending hashtags because they remind me how big the world is and how small my little corner is compared with it.

• Just as the umlaut mark was originally a tiny ‘e’ written above the vowel, and the Spanish ‘ñ’ was originally an ‘n’ with another ‘n’ above it, there's also a Greek diacritical mark which is a tiny iota written below a vowel.

Film producers have a profound, almost fervent respect for the works of the great composers of the past, because they are in the public domain.

According to U.S. to Argue It Never Left Iran Nuke Deal, in Bid to Force Arms Embargo, Report Says :

U.S.-Iranian relations have been bitter since the Islamic Revolution toppled the U.S.-backed Shah of Iran in 1979 and ushered in an era of theocratic rule.

That is a heck of a sentence there.

Some might observe that U.S.-Iranian relations had been bitter at least as far back as 1953, when the CIA and the U.S.-backed Shah of Iran toppled the democratically elected Iranian government in 1953 and ushered in an era of brutal dictatorship.

Ed Kilgore, New York Magazine:

With Bernie Sanders’s decision to suspend his presidential campaign, Joe Biden is not just the “presumptive” Democratic nominee, but the putative nominee: It’s in the bag unless something extremely weird happens.

Apparently “77-year-old man dies” is now “something extremely weird”.

I do get a lot of spam from organizations people and offering to supply “content” for my blog, and more often than not they say something like:

I was just browsing slatestarcodex.com and we'd be really interested in working out a deal for placing relevant, non-promotional content on your website.

I try writing back to these people because I want to know where they got the idea that I own slatestarcodex. So far none of them has returned my mail so it remains a mystery.

Today's spam solicitation was more amusing though:

Hee hee hee.

Sorry, Kenny, not shitty enough!

The pharmacy informed me that they now have delivery service, so I said sure, deliver my prescription.

I had a very clear picture in my head of what would happen: they would fill the prescription at the place down the street, then hand it to someone who would carry it to my door. My wife had independently had the sanme picture.

But no, instead they transmit the order to a central location and ship it by U.S. post. Why did I expect anything different?

I went to the store this morning. Some things were sold out, most things weren't.

The dumbest thing I noticed that wasn't there:

Massachusetts state law provides:

When the board of health of a town shall deem it necessary, in the interest of the public health, to require a resident wage earner to remain within such house or place or otherwise to interfere with the following of his employment, he shall receive from such town during the period of his restraint compensation to the extent of three fourths of his regular wages;

Very good!

provided, that the amount so received shall not exceed two dollars for each working day.

Thanks to Chas. Owens for bringing this to my attention. The cartoon panel is taken from Webcomic Name. I wonder when this law was enacted? The web site does not say.

• To “slub” is to pull out and twist a bit of fiber from a wad, in preparation for spinning it. The twisted lump at the end is also called a slub. I had previously only known slubs as the little bumps, left over from the cocoons, that you see on raw silk dresses.

• The Pandrol clip is named for its inventor, a guy named Per Pande–Rolfson.

• All the Scandinavian versions of “Peter” are missing the ‘t’: Per, Pehr, Peer, and Pär. What happened to it?

• “Impropriation” is when ecclesiastical property is placed under control of a layperson. The diary of John Evelyn mentions that the tithing in some parish was impropriated to his uncle, who then gave £20 per year back to maintain the church. Why didn't the parish just keep the tithes, then? (Maybe they came to less than £20? I really don't know.)

The phrase “other fish to fry” goes back to the 17th century:

1660 John Evelyn Diary and Correspondence (1857 ed.) vol III p. 132 “I fear he hath other fish to fry.”

According to a sloppy Google Books search, variations appear with these frequencies:

• “Bigger fish to fry”: 25
• “Other fish to fry”: 20
• “Larger fish to fry”: 1

It seems to me that “larger fish to fry” ought to mean the same as “bigger fish to fry”, but it sounds weird. Is that just because it's unusual? Or is there some pattern to the way English uses ‘bigger’ and ‘larger’ from which one could predict that ‘bigger’ would predominate here?

A (Dutch) co-worker informs me that the Dutch version of this phrase is “andere katten te geselen”. Instead of frying fish, they are flogging cats. Who knew that the Dutch were so depraved?

(Not really related: OED Quick Search for “other fish” asks: “Did you mean: motherish?”.)

In his book Chess is My Life, Viktor Korchnoi wrote: “I went up to the controller and asked whether it was legal for me to castle when my rook was attacked. I was assured that it was. Afterwards, this incident was cited as being an indication of how extremely tired the players were. But in fact, out of the 2500 games that I had played, there had never been an instance where it had been necessary for me to castle when my rook was attacked, and I was not sure that I understood correctly the rules of the game!”

(Source)

In 1974, Korchnoi was playing Karpov in the Candidates final for the right to challenge Fischer. Midgame, Korchnoi strolls over to the arbiter O'Kelly de Galway, and asks if he can castle while his rook is attacked. O'Kelly looks at him stunned, but answers yes. "It had never come up before," Viktor shrugged.

Waldo Peirce and his friend John Reed booked passage together on a freighter from Boston to England. As the ship was leaving Boston Harbor, Peirce decided that the accommodations were not to his taste. Without a word to anyone, he jumped off the back of the ship and swam several miles back to shore. Reed was then arrested by the ship's captain for the murder of his vanished travelling companion and thrown into the brig. When the freighter eventually arrived in England, Peirce was at the dock waiting to greet his friend Reed—he had dried himself off and taken a faster ship to England.

Yesterday during a discussion of the necessarily relative nature of “potential energy”, the topic veered into what it would be like if we measured people's height from the center of the sun instead from to the surface of the earth.

Katara: Everyone would be the same!

Me: Yeah, but we'd all be taller at night than during the day.

The Big Dictionary has no citation for “pizazz” from before 1937. The earliest one is:

Pizazz, to quote the Harvard Lampoon and Harpers Bazaar, is an indefinable dynamic quality. (New York Times, 26 Feb 1937)

This strongly suggests that an antedating could be obtained by going through contemporary issues of Harvard Lampoon and Harpers Bazaar.

The spelling of pizazz has always been variable, but I was surprised to learn that during the 1960s it was sometimes spelled “bezazz”.

Weird.

A while back I complained that the sufficx ‘-potamus’ wasn't widely-enough used. Today I saw this Reddit comment:

The only people I see with this quote on their car or on a t-shirt is the stay at home dependapotamus that complains about everything…

All the news that's Rupert Grint.

I dreamed that it was well-known that George H. W. Bush habitually cheated when putting together jigsaw puzzles, to persuade people that he was better at doing them than he really was.

In the dream I imagined that he would take a piece out of the puzzle and put it on the table. Then, when someone came by who might observe, he would pick up the piece he had removed, look at it for a moment, and put it instantly in the right spot.

But when I suggested this to someone else, they said that what he actually did was even more devious and underhanded. I was not able to find out what it was.

I also dreamt I was visiting Shanghai and left my money on the bus.

I think I once estimated that around one-third of the blog posts I start writing never see publication, for one reason or another.

(Some do surprise me by flowering years later.)

I commit them to the repo anyway. Recently committed:

1. The Philadelphia Federal Reserve Bank did a study about racially-restrictive clauses in real estate deeds between 1920 and 1933, and this turned up in the newspaper. The paper tried to suggest that the neighborhoods with the greatest incidence of these rules were still the ones most segregated 100 years later. I spent a lot of time extracting and analyzing data, and eventually ran out of steam because I felt that the original claim was too vague to refute, and the available data wasn't good enough to draw any useful conclusions anyway.

2. I was thinking about the (not-exactly-a-joke) claim that

   A monad is just a monoid in the category of endofunctors

   and I realized hey, if I try to explain the minimal amount necessary to understand what that means, and not try to drag in all of category theory, I could probably do it clearly and briefly.

   Then I tried and didn't succeed.

3. This third article is really hard to summarize and all I am going to say about it is that it identifies a commonality between a not-available-in-stores gizmo for improving eyesight, a Jughead comic I read as a child, and the presidential campaign of Michael Bloomberg. I would love to finish this because it might be stupid but gosh, at least you weren't going to read it anywhere else.

4. My work on designing the most dissonant possible musical scale has stalled in peripheral technical issues.

5. The saga of Fenchurch the Octopus and Philadelphia Traffic Court, mostly as told by my wife.

6. Yet another article about what goes wrong when I try to write Haskell programs. Except I think I may have figured this one out at last!

7. Let !!G(n)!! be the (standard) Gray code for the number !!n!!. This is a permutation of the integers !!0\ldots 2^{n}-1!!. What's the period of this permutation? (Spoiler: extremely short!)

8. A long article about the seaports on the Great Lakes and how the one on Saginaw Bay is mysteriously missing. Except that it's not, it's called Saginaw.

That's just this month. Also Shreevatsa R. sent me a very significant update to the Kurt Gödel loophole in the U.S. Constitution series, and I really want to write some articles about Milton Street, Willie Singletary, Vanessa Lowery Brown, Movita Johnson-Harrell, and the rest of the Philadelphia local-government-to-prison pipeline, but those aren't incomplete because I haven't started them.

Changing “day” to “duck” in various sayings and clichés works pretty well. I asked my co-workers for examples and they helpfully came up with

• Every dog has his duck
• It's always the same thing, duck after duck
• All in a duck's work
• Shall I compare thee to a summer’s duck?
• Hit payduck
• As happy as the duck is long
• The shortest duck of the year
• Like sands through the hourglass, so are the Ducks of our Lives
• Another duck, another dollar
• Tomorrow, and tomorrow, and tomorrow / Creeps in this petty pace from duck to duck
• Watch therefore, for ye know neither the duck nor the hour

Various combinations such as duck bed, duck camp, duck room, duck ticket, duck trader, duck trip, duck uniform, and duck-wear.

Some phrases are just confusing:

• Give us this duck our daily bread

• I just want to bang on the drum all duck

(Which unfortunately suggests that what was meant was “bang on the duck all day”)

• An apple a duck keeps the doctor awuck

And finally:

• Toduck is a good duck to die

although “today is a good day to duck” is pretty good.

(By the way, ‘duck’ (the verb) is derived from ‘duck’ (the bird) because the bird is always ducking its head into the water to feed. So “today is a good day to duck” can be interpreted either way.)

The Big Dictionary has many useful quotations:

The state was seen as an educator leading ‘villagers’ out of the ignorant dark of backward thinking into the shining duck of development.

What's the point? All this backbreaking, brain-aching work that people do duck in duck out — why?

We will all arise from the darkness of death unto the brilliant duck of eternal life.

One rotary kiln… has produced an average of 75 to 90 tons of… pyrites cinder per duck.

Jupiter's year contains 10,000 of his own ducks.

I was (as nearly as I could calculate it) some three ducks distant…

In a Wonderland they lie / Dreaming as the ducks go by…

Handling unsubscribe requests is not rocket science.

Sufficient unto the duck is the evil thereof.

• That clever saying about how the third time is enemy action is attributed to Auric Goldfinger.

Lately I've been having fun pronouncing words as if they were German, even when they aren't. So far, my favorite is “wormhole”.

A long time ago I was at a job interview, and the interviewer said she was concerned that the work wasn't hard enough for me, that I might become bored, find myself hating the job, and stop doing any work while continuing to come in.

I said no, before that happened I would certainly quit. Or else show up one day with a shotgun and murder everyone in the office.

There was a long pause.

“I probably shouldn't have said that.”

I got the job.

• “Potion” is not related to “potent” (from Latin potēns, “powerful”, akin to “potentate” ). It is from pōtāre, to drink. It is, however, from the same root as “poison”.

• In classical Greek, the name of the letter ε was simply “εἶ”. The name “epsilon” (ἒψιλόν) didn't arise until the middle ages.

According to this 2004 New York Times article, United Methodists Move to Defrock Lesbian:

few Methodists expect church to reach point of schism…

and yet here we are.

• Czech has a letter Ť, which is written lowercase as ť.

The Bosch web site said I should call if I wasn't sure whether their blade would fit in my tool. So I called. After about ten minutes on hold, I got the rep and asked my question: "Will your T-shank blades work in my Black and Decker handheld jigsaw?"

"I need the part or model number of the blade."

"I am interested in model T130DG."

"That is a T-shank blade. Does your saw take T-shank blades?"

"Yes, that is exactly what I am asking."

"Our blade will work in your saw, if your saw is compatible with T-shank blades."

Thanks, Bosch. I will decide to buy your blade, if your blade is something that I decide to buy.
