How fateful? 4 years ago

I think that's a common misunderstanding about who owns what in a marriage. I'll quote Matt Levine on this:

One thing that I find a little weird about the Bezos divorce is that there are a lot of claims that it will make MacKenzie Bezos “the world’s richest woman.” I suppose there is a technical sense in which that is right, but it assumes not only that she will have a right to half of Jeff Bezos’s assets in divorce, but also that she has no such right in marriage. That strikes me as a strange way to think about marriage, and about the “community property” laws that might give her half the assets in divorce. (Surely those laws imply that she is in a sense a joint owner now?) I would have thought the more straightforward analysis is that she is the world’s richest woman now, because she is a member of a married couple that has more money than any other single person or married couple on the planet, but I guess that is not how the scorekeeping works.

How fateful? 4 years ago

The incentive to do what exactly? Break up a good marriage to get half of the common assets (minus many many expenses)? How is that better in any way?

All the other answers in the thread focus on maximizing head-to-head score. I'll try to answer the question for the goal of greedily maximizing your own score.

Using the same definitions from the article, we now have (for a 2 person game):

  Q_i = -P_i + (1 - sum_{j=1..i}(P_j))
Where the first term is for the case of choosing the same number as your opponent, and the second when it's larger than your opponent.

Now solve the same set of equations, but with our new Q_i. Solving Q_1 = Q_2 analytically is easy, then Q_2 = Q_3 and so on... You get P = (1/2, 1/4, 1/8, ...)

So that's the result for this specific 2-player game. You could also ask about the 2-player game with tie=t for any negative t (the above is for t=-1). Now we get

  Q_i = t*P_i + (1 - sum(P_j))
Again, solving Q_i=Q_{i+1} is easy and gives
  P_{i+1} = (t / (t-1)) * P_i
For example, if t=-2 then (using the fact that all P_i's sum to 1): P = (1/3, 2/9, 3/27, ...)

I did not try to tackle the 3-player game with tie=t.

On the contrary, it should be on by default for every build configuration! If you move to a newer compiler version and the compilation breaks, then you just saved yourself valuable debugging time. The alternative is that the new compiler has a new optimization that causes your code to break in runtime. You can always disable specific warnings if you think they're not relevant for your code.

Musk signed a contract with an exit clause.

There are some exit clauses (like Musk not getting financing from his banks) but they don't apply here. Specifically, there's no exit clause for the bot percentage.

If it was a promise it could be written on a hallmark card.

Are you just trying to change the meaning of the word promise? Most people would agree that if you break a promise you pay a price - it might be a social one in case of a promise between friends. Or it might be a financial price in case of a written & signed promise, a.k.a a contract.

Follow-up question: what if other countries follow suit, especially ones that don't use a Latin-based alphabet? Egypt is formally called "جمهورية مصر العربية" in its native language - should that be recorded as the ISO Full name for EG?

Same here. In fact I lost my 1000+ day streak 2 months ago (a newborn will do that to you) and haven't done a single Duolingo lesson since then. However, I did replace it with another app called DuoCards (no relation to Duolingo, AFAICT) which is great for memorizing vocabulary using spaced repetition. Duolingo used to have a companion app that did something similar, but they closed it a year ago. Anyway, they lost my subscription.

There's a link in the article to a paper (N2023) proving this is not constant time. The issue is that as you delete elements, and the hash table becomes sparse, finding the next nonempty bucket is not so fast. However, I believe that the paper conveniently glosses over the fact that there will be rehashing into a smaller table which would fix this issue.

This can happen anywhere, not only on software. I once bought a set of 10 or so entries to a climbing wall. Some time later I wanted to use it and was told that it was no longer valid. There was no "valid by" date on the card, but I was told that the place transfered ownership and that this decision to not accept the old card was ok'ed by the lawyers.

At least for software you can keep a copy of the installer. Unless it checks the license with the server, then you're screwed...

skipping all the chimneys, vents and fans needed to remove the smoke from the kitchens.

Every kitchen needs ventilation, even if it's fully electric. And if a restaurant is doing a lot of frying this ventilation needs to go somewhere it won't be a nuisance to the surrounding.

it has been trained to produce high-quality outputs, not to ensure the validity of mappings.

Just nitpicking here a bit. It has been trained to ensure the validity of mappings, but only for mappings of valid prompts, where "valid" is vaguely "things that appear in the training set". On the other hand, it wasn't trained to ensure the validity of mappings of invalid prompts to images. It's an open question what that would even mean - someone in another thread here suggested it should output "not a valid prompt" in this case.

I had to stop in the middle of the article due to all the annoying animations.

But something that stood out to me is this:

For consequences, I came up with a three strikes and you are out rule.

and then

I wasn’t ready to inform them about what was going on until I had processed all of the facts, so I just pressed on with the lectures. My goal was to have all of the forms filled out and emailed before the next midterm. I tried as hard as I could. But, I couldn’t get it done. I had to give the next midterm, and I knew that probably meant a bunch more cheating.

So basically, this professor know about "low-impact cheating" (cheating in quizzes, where "[t]he quizzes were low stakes"), but instead of saying anything just kept pushing forward.

I wonder if anyone even told those students up front in clear terms that sharing answers on the quizzes was not allowed. In school we're often told to co-operate in assignment. Where is the line between an assignment and a quiz?

Just letting the whole group slide gradually into cheating territory is a lose-lose strategy.
