This seems vaguely familiar, but I don't think I've read it yet: https://arxiv.org/abs/2603.09678v1 "We evaluate five frontier models across five prompting strategies and find a dramatic capability gap: models achieving 85-95% on standard benchmarks score only 0-11% on equivalent esoteric tasks, with 0% accuracy beyond the Easy tier"

Sad news today: C.J. Cherryh has announced that there will be no more books from her: https://www.facebook.com/share/p/1F27iFDAzo/

I've greatly enjoyed all her works, and even the recent "Hinder Stars" (collaboratively written with her longtime partner Jane Fancher) show an ability to build a tense, engaging narrative out of what is essentially an economic mystery.

Her works engage with "the other" in a way that insists thinking beings don't necessary all think alike, while also showing an optimistic view of human adaptability and versatility.

One of my favorite stories about Cherryh's work comes from a different author, Jo Walton, who has talked about playing Elite with her partner and imagining themselves as a Family on a trading ship, splitting the economic and navigation responsibilities between the pair of them.

Her impact and output have been immense, and I'm glad we get to keep her for a while longer, even if "the body of work is what it is."

Of two minds about my early-morning talk. Is it actually a full 40 minutes? Will session 0 eat into the time anyway? Or should I bring some art supplies so we can hang around making some serial art? #Minnebar

Mr. 0 (from #OnePiece) and Baroque Works have a culture problem.

Mr. 0 does not tolerate failure -- the price is usually death. In most organizations, this is standard villainous best practice. While henchmen overestimate their chances of long-term success [see Ming 2013], perceived value from leadership roles creates an equilibrium favorable to the overall criminal enterprise.

However, the Baroque Works agent class seems to be mainly assigned to unpleasant tasks on minuscule islands. Thus, the opportunity for increased status within the organization is balanced by shittier jobs.

What is a rational henchperson to do? In this case study, we will show that the optimal strategy is moderate success at a level unlikely to attract attention, as promotion is usually fatal and leads to net negative utility. As a result, the Rogue Works organization shows a lack of innovation and initiative...

I had a very simple theory for this run. I had True Grit, Bludgeon, and Stampede. Exhaust every other card in my deck so that I'm throwing down a free-cost Bludgeon every turn--- right?

Instead I went on a shopping spree because I had Monkey's Paw so it was hard to turn down additional powers. And if I'm playing _two_ attacks per turn, might was well have something else? And if I'm exhausting cards then I should get Howl From Beyond...

This is my problem, I can see synergies between cards but stop thinking at the whole-deck level.

Cleared Ascension Level 5 anyway but was taunted at the end with the "large deck" achievement.

@aparrish I had a similar question about AlphaEvolve which produced some genuinely new mathematical results but... there was no comparison to any other way they could have spent the same amount of compute $$$. Would a more traditional evolutionary algorithm or other search have been more efficient? We don't know because nobody's willing to put the same amount of GPU-hours into it. On the other hand, I have seen comments like this one from John Regehr about how LLMs are basically the first thing that is effective at all at program synthesis https://mastodon.social/@regehr/116071281519001618

@skewray Well, I think there was a recent result that the Whitespace language is pretty poorly executed by LLMs, so there's a form of steganography at work there. We need to make languages that are ignored by scrapers -- maybe one in which the EICAR code serves a cruicial purpose? Trying to find the Whitespace reference I was thinking of, I found this paper (which might have been the source of the claim) https://arxiv.org/abs/2603.09678v1

Four shots from wandering around Montreal this evening:

1. A skyscraper with cranes attached doing some sort of maintenance (I haven't looked up which one it is yet, I think I prefer the mystery)

2. The canal that was once the main link between ocean traffic and lake traffic. Still operational but only for pleasure traffic, according to the signs.

3. A big neoclassical box full of bureaucrats.

4. A decaying industrial ruin on Rue Mill.

A good time today at the Montreal Museum of Archaeology and History today; not so many photos. It's an interesting site with a layered history of literally the first French settlement on the island -- then an inn, warehouses, the first sewer collector in North America, and a major commercial and governmental building. The last unfortunately wasn't built well for the conditions and had to be destroyed after its pilings rotted. But you can see its foundations preserved (including the rotting pilings!) as well as the site of the very first palisade.

There was a lot on the 1701 peace treaty between the French, allied First Nations, and the Iroquois / Haudenosaunee.

There is also a fair amount on the modern transformation of Montreal into a diverse metropolis -- the takeover by the British, the waves of immigration, a little bit on the 1967 exposition and 1976 Olympics.

@crazybutable Session 0 has historically not started in a timely fashion and so the speaker has tended to run long (eating into at least travel time, if not session 1 itself.) It's been a wart on an otherwise well-run day. Who knows this year because it's not an outside speaker. But, yeah, I'm scheduled for session 1 on the opposite side of the site from the cafeteria.

@christianp the differences 2,4,4,5,9 do appear multiple times. :) To me these seem like they are close to the triangular numbers. a(1) = 1 = T_1 a(2) = 3 = T_2 a(3) = 7 = T_3 + T_1 a(4) = 11 = T_4 + T_1 a(5) = 16 = T_5 + T_1 a(6) = 25 = T_6 + T_2 + T_1 Guess is a(7) = 32 = T_7 + T_2 + T_1 a(8) = 40 = T_8 + T_2 + T_1 a(9) = 55 = T_9 + T_3 + T_2 + T_1 ? But I am also guessing that is just coincidence. I spent too long looking at https://oeis.org/A327629 to see if its partial sums had some reasonable interpretation.

John Chu's "The Subtle Art of Folding Space" is great!

It is also the most chip-designer science fiction novel that ever noveled. I don't know how much of this is obvious to people who have not worked with computer hardware engineers.

It features tasty food and a supremely uncomfortable sibling dynamic (what is a little murder attempt between sisters.)

@poleguy The paper I linked downthread tries several approaches! It does not look like (in the current models) a description of the language is good enough. An interactive session does help somewhat in their experiment. I would like to see a non-Esolang example, although the effect seems very strong there. While (b) is certainly a questionable assumption, I think it is currently borne out by this and similar results -- the models get good by having training sets that are relevant, rather than developing transferrable knowledge.

@nicole@tietz.social Now I want to carry out a study with prompts that are "you are an expert X" and "you are a non-expert X" to see if there is any objective difference. I'm very worried that "expert X" selects for insecure writing from the corpus that proclaims expertise to cover dubious judgements or engage in self-puffery. The whole "please do a good job" or "your existence depends on it" family of prompts is rather baffling.

One late addition I learned about today from @attoparsec's latest video on Gray codes: https://www.youtube.com/watch?v=Z9X3dH5LjrM Samuel Beckett wrote a television play that I think counts as a work of serial art. It features four performers entering and leaving the square stage (and pacing it in a fixed pattern) such that all 16 combinations are explored: https://en.wikipedia.org/wiki/Quad_(play) The twist here is that the "Beckett-Gray" code that he wanted does not exist for n=4. "He wished the actors to enter and exit so that the actor who had been on stage the longest would always be the one to exit." https://en.wikipedia.org/wiki/Gray_code#Beckett%E2%80%93Gray_code This is possible with 2 or 5 performers, but not 3 or 4.

From today's #MoneyStuff, the question is raised: if Elon Musk is found to have violated securities law and must disgorge $143m in unjust earnings, but not enough specific victims can be found, what should happen?

High priced lawyers are busy arguing that courts cannot order repayment unless it goes to specific victims. And if no such victims can be identified then Elon gets to keep his cash, presumably. Giving the money back to the market makers who were the last link I the sale seems like an unjustified windfall. I am fine with the Treasury just keeping it, but I can see how that moves the cash from one category of penalty to another.

This I think is an area where cryptocurrency does actually have a useful innovation to contribute. If Mr. Musk has contributed a fraud on the market at large (a large distributed system in which it is hard to apportion losses.that match his gains) then we turn that around and spread the restitution out in a similar distributed fashion. Elon should have to buy a basket of equities and the "burn" it, reducing the number of shares that exist and thus increasing value for everyone else. (And also for him too, but we can solve that with the right math.)

There are no doubt some practical obstacles to overcome but I don't see any block in principle to the clearinghouse agreeing that those shares no longer exist.

Two Regent ascensions (3 and 4) tonight by basically just ignoring the stupid sword and spamming stars. Unfortunately I'm coming to believe the ability to bank up an unlimited amount of a resource is just broken.

3x Black Hole on this one which is 9 sweet points of global damage for gaining _or_ spending stars. The build is otherwise trash but it doesn't matter because Just Keep Spamming Stars.
