Today I got worried that I have been mispronouncing “Tanzania”.

But I haven't been.

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.
