Huh. Maybe the data structure underlying my next project should be #quipu. A 600 year track record that's open to hand implementation, literally, might be considered a solid enough basis, yes? https://indiandefencereview.com/thought-was-just-knots-scientists-say-inca-invented-worlds-first-computer-system/
Scientists Say the Inca May Have Invented the World’s First Computer System 600 Years Ago

Before silicon, before writing, the Inca were computing. Scientists just proved their 600-year-old knotted cords can run spreadsheets, encryption, and file systems.

Landscape khipu: A theory that thousands of holes dug into a hill in Peru are a sort of storage and accounting system similar to the knot tying accounting technology

5,200 holes carved into a Peruvian mountain left by an ancient economy

For nearly a century, a strange band of thousands of holes carved into a Peruvian hillside has defied explanation. Stretching for nearly a mile (1.5 km) along the edge of the Pisco Valley, Monte Sierpe – "serpent mountain" appears to be a deliberate, repetitive and almost mathematical feature – but…

"Structures cosmiques : une famille de géantes"

I was yesterday on France Culture to talk about the discovery of the Quipu Supercluster and other large scale structures.

Structures cosmiques : une famille de géantes

Comment Quipu, structure parmi les plus grandes, a-t-elle été identifiée ? De quoi sont composés les filaments de galaxies et de matière noire qui forment les structures de l'univers ? En quoi leur identification permet-elle de préciser notre compréhension de la cosmologie ?

#Quipu (/ˈkiːpuː/ KEE-poo), also spelled khipu (Ayacucho Quechua: kipu, [ˈkipu]; Cusco Quechua: khipu, [kʰipu]), are record keeping devices fashioned from knotted cords. They were historically used by various cultures in the central Andes of South

Human hair khipus reveal Inca record-keeping was used by both elites and commoners
 
A recently studied 500-year-old Inca khipu (Quipu) has overturned assumptions about who created these intricate thread-based documents. The study, published in Science Advances, suggests that khipus—formerly thought to be the domain of high-level imperial officials—were also made by non-elite members of society...

« On n’a jamais vu quelque chose d’aussi gigantesque » : Quipu, la structure de 1,3 milliard d’années-lumière, devient l’objet le plus vaste de l’Univers - Enviro2B

EN BREF 🌌 Quipu est la plus grande superstructure cosmique jamais découverte, avec une taille dépassant 1,3 milliard d’années-lumière. Elle contient environ 200 quadrillions de masses solaires, influençant significativement l’évolution des galaxies. Les superstructures comme Quipu perturbent les observations cosmologiques en modifiant le fond diffus cosmologique et les mesures de la constante de Hubble. Les

I had the pleasure to be interviewed by Alexandre Morales for France Culture, to talk about the discovery of Quipu, one of the largest known structure of the Universe. It will air tomorrow morning at 6:52.

Here is the press release by the authors of the discovery at MPI Garching https://www.mpg.de/24197951/largest-superstructure-in-the-nearby-universe
