I've given up on finding relevant low-level CUDA(? tacit? asm??!!) code from Hsu*, but I did push the following to my to-watch stack

Does APL need a type system

Guess it's time to reverse whatever else I can find

*Bad faith, or just a run o' the mill, aka compleatly forgiveable profiteering?

He must be referring to https://dl.acm.org/doi/pdf/10.1145/2935323.2935331 ?

Just looking at refs for the moment: Henglein and Hinze's discriminators are interesting, whenever you come back up for air. (are they also amenable to sorting codata?)

The oft-cited R Bernecky is, IIRC, also known as "Boolean Bob" for his SWAR-style algos. EDIT: nope, confused him with R Smith: https://aplwiki.com/wiki/Bob_Smith

(I once asked Boolean Bob if any of his tricks went back to the card processing days —I could even believe the keyed tree* might?— but he was too young to know, and the people he'd have liked to ask are no longer available.)

EDIT: Aardappel also has some interesting languages: https://strlen.com/#programming-languages

* for manipulating Bills of Materials despite the linearity of card decks?

EDIT2: compare "§3.2.1 Constructing Node Coordinates" (p34) with [T in "Table 1.19 Full list matrices of the tree of Fig. 1.16" in A Programming Language (p50): https://archive.org/details/aprogramminglanguage1962/page/n6...

[all three appear to be 1-origin, probably due to the phenomenon mentioned in the footnote on p49 of APL]
Thanks!

[Too low global b/w to feel the adrenalin.. wow.. what was your deduction chain for figuring how BoMs was next item on my stack? Guessing you started from assumption that pure bits mongering are not on the boundary of my ikigais(yet)]

On the heap, I (re)surfaced "Typed Array Intermediate Language" slides, but too low (local) b/w to try to find out^W^W^W^W sus out if this or smth v similar is already in dyalog.com's workflow.

What were those slides about formalizing Euclid ?

[Medium b/w vibing that multiplicity of edits is a precise estimate of flow-of-war, ~ webpage memory usage is an accurate estimate of just how well run the entire organization is..]

still haven't refound the slides — every 5 or 6 weeks I get a new idea of who it might have been, but so far to no avail...

[BoMs were complete coincidence]

Edit: really appreciated WvO recording his early hopes.. have seen undergrads doing this, but a doc? a first for me!

Slides & conspiracies..

For an vulpine organ they speak very confidently of the f-o-w

https://xcancel.com/benln/status/1873459290562056566

Using kendō vocab I think what they're trying to say with f-o-w is to avoid 2 of the 4 fails: 疑, and (or at least?) 惑.

(interesting that 平常心 is unmarked, while in english the desired state of mind[heart] is marked)

No slides yet, but I finally dug up the quotation I'd promised you last year: Körner, The Pleasures of Counting (1996) p.413 ch.17 "Time and chance" in a footnote (arrived at via a path starting with Enigma decodes!):

> Social Darwinism applies the Darwinian doctrine of survival of the fittest to human society. Rich social Darwinists take wealth as the best indication of fitness to survive, academic social Darwinists take intellectual achievements as the best indication and so on. They are often haunted by the fear that the unfit do not understand this and may outbreed the fit.
