Stambovsky v. Ackley, a case often taught in US law schools, dealt with the sale of a house which the seller had previously described as haunted. The buyer wanted his down payment back after finding out about the house's reputation. He won on appeal.

The contract said the house was sold "as is"; the seller said that clause should apply to more than just the house's physical condition. The court's remarks on that point include my favorite line in the ruling:
Finally, if the language of the contract is to be construed as broadly as defendant urges to encompass the presence of poltergeists in the house, it cannot be said that she has delivered the premises "vacant" in accordance with her obligation under the provisions of the contract rider.
Back in 2010, air traffic controller Gregory Gish assigned five‑letter names related to Donald Trump to a bunch of waypoints near the Florida coast. At the time, some pilots were offended enough that they refused to fly departure routes through those waypoints. (Mr. Gish has since retired.) A 2010 newspaper article about the waypoint names said Trump was flattered, having said "It is my honor." In July of this year, when Trump was in the news for crude remarks he'd made about immigrants, the FAA said it would rename the waypoints. Trump made like this was no big loss, saying that the waypoint names were "an honor I never knew I had." I leave to readers the question of whether Trump forgot about the waypoint names or is simply full of shit.

I was wondering what the new names would be. The FAA finally issued them this month and alas they are not memorable:

old name new name latitude longitude
UFIRD CRRMN 26.6790° N 80.0122° W
DONLD RIDRR 26.7492° N 79.9352° W
TRMPP RBACK 26.8122° N 79.8715° W
IVNKA SLIDZ 26.9236° N 79.7085° W
And just to finish with something not Trump‑related, a departure route from another southern Florida airport uses one of my favorite waypoints: ZAPPA, at 26.6300° N 79.0979° W. In 1989, I told my friend Brian that if I should ever say I was thinking about moving to San Francisco, he should remind me that it's cold and damp there. A year later I said I was thinking about moving to San Francisco and Brian reminded me that it was cold and damp. I said I was going anyway.

Living in SF in 1990 was the first time I took an extended break from programming work. I was still coming to terms with being HIV‑positive, I was burnt out on working, and I was looking for a change of scenery. There was no guarantee that living in SF would be to my liking, which made it all the more pleasant when it turned out well. I rode my bike a lot, I lucked out finding a boyfriend, I had time to read lots of stuff I wanted. I felt better all around and was rejuvenated when I went back to work around the end of the year.

I have some affection for every city I've lived in and also for many cities I've only visited—but largely for different reasons in each case. I found SF remarkably livable in the sense of having clean air for a city of its size, a mild climate, and great topography. But that description doesn't do justice to why I liked it. There's more, some of which is hard to put into words. Fred

The distribution of prime numbers is related to the values at which a certain function ("Riemann's zeta function") evaluates to zero. Long story, but it's a big deal to mathematicians.

From The Penguin Dictionary of Curious and Interesting Numbers:
Riemann conjectured that, considered as a complex function with complex roots, [the zeta function's] roots all had real part equal to 1/2. So important is this possibility that many mathematical proofs have been published that assume that Riemann's hypothesis is true.

This profound conjecture is generally considered to be the outstanding problem in mathematics today. It is known that the first 1½ billion roots are of the conjectured form. However, many phenomena of this type are known in which trends for small numbers are misleading.
Suggesting that 1½ billion instances constitute a small‑numbered trend: humor possibly lost on one Christopher Hirst, who called that book "a volume which none but propeller‑heads will find either curious or interesting". (Mr. Hirst is "an award-winning food writer".)

A proof of the Riemann conjecture would apply to an infinite number of roots, dwarfing the 1½ billion examples (and no known counterexamples) verified so far. This looks like a chance to segue back to Pascal's wager. 1,500,000,000 versus ∞: the number of seconds in an earthly lifetime versus eternity. (I've passed the 1½ billion second mark, although Pascal and Riemann each only made it to about 1¼ billion.)

In section 233 of Pensées where Pascal describes his wager, he also speaks of the incomprehensibility of the infinite:
We know then the existence and nature of the finite, because we are also finite and have extension. We know the existence of the infinite, and are ignorant of its nature, because it has extension like us, but not limits like us. But we know neither the existence nor the nature of God, because He has neither extension nor limits.
Thanks to Cantor, we are no longer ignorant of the nature of the infinite.

A girl in my brother's AP Calculus class named her cat Riemann. A couple days after my recent posting on Pascal's wager, the NY Times ran a column by Professor Gary Gutting that describes a variant:
I propose to reformulate Pascal's wager as urging those who doubt God's existence to embrace a doubt of desire rather than a doubt of indifference. This means, first, that they should hope—and therefore desire—that they might find a higher meaning and value to their existence by making contact with a beneficent power beyond the natural world. There's no need to further specify the nature of this power in terms, say, of the teachings of a particular religion.

The argument begins by noting that we could be much happier by making appropriate contact with such a power. ...
Well. I might really like there to be a fountain of youth, but that doesn't mean I should go all Ponce de León. And if, in an ordinary spring, I found what I believed was a fountain of youth, I'd be living in fantasy at the cost of overlooking how fine spring water is for its own sake.

Professor Gutting proposes a doubt of desire rather than a doubt of indifference. To the extent he means desire for a particular seductive result, I can't accept his proposal. I'm with Bertrand Russell:
Why not admit that metaphysics, like science, is justified by intellectual curiosity and ought to be guided by intellectual curiosity alone? The desire to find comfort in metaphysics has, we must all admit, produced a great deal of fallacious reasoning and intellectual dishonesty.

The code of the spy has always been, "Never celebrate your successes or explain your failures."

I'd rather have dinner with a spy than a politician, and not just because they'd have more interesting stories to tell. I'd be interested to see what kind of person has the austere discipline it takes to work in the shadows. Spies are highly trained; politicians not necessarily. Missteps in espionage can kill you or worse; missteps in politics need not be any impediment to advancement.
