New article! A user *cough* @aras *cough* is reporting full system freezes while using Superluminal on Linux. What do you do? Cry? Well, we did a little bit.
But we also dove into the kernel...again, this time finding & fixing several issues in eBPF's spinlock implementation. Read all about it:

@rovarma great post! (kinda proud of myself that my very eyeball-y guess “200ms stalls” turned out to be almost exactly correct :))
Would be good to clarify why only certain kernel versions were affected, since now not clear why only I could see the problem initially

@rovarma Great post. I can't wait to use Superluminal on Linux :)

@aras Good point! Added a bit about that in the conclusion.
TL;DR: usage of rqspinlock in the ebpf ring buffer was introduced with kernel 6.15, and our development machines (and most of our alpha testers) are on Ubuntu, which runs an older kernel than that (6.14).
It would eventually have shown up for us too, once Ubuntu caught up.

@aras I’m planning on switching my dev machine to Arch, which is on the bleeding edge kernel usually, so that we’ll spot issues like this faster locally in the future

@rovarma nice! And again, oh man what a debugging story. Massive props both for writing it down, and for working with kernel folks to actually fix it. ❤️

@futurebird Things that size would be ground to dust 200 million years later.

In the book After Man, they portray future ants who build boat-like colonies that advance out into lakes.
This inspired me to world-build ants who make submarine hives which can sink or float like a nautilus by changing the internal pressure of their home.

How much harder would tools and technology be for us to recognize if they were made on an ant-size scale?
No one would look at a tiny flake of flint and think "yes something intelligent worked that into a point"
Also ants would use a lot of bio-tech. Their spaceships would be based on massive pupae.

Cloud pubblico e democrazia, dove si misura oggi la sovranità. Un interessantissimo articolo della prof.ssa Ginevra Cerrina Feroni
«La disciplina del Piano Strategico Nazionale tende a garantire la sovranità infrastrutturale/sicurezza, ma la sovranità applicativa (chi può fare cosa coi dati) rimane frammentata e spesso scaricata sulla singola amministrazione e sul singolo contratto.»

Since all ants can walk they are all ped ants I guess. Little know it alls.

@futurebird I once ran a short-lived TTRPG campaign set in the Cretaceous, where the players were members of a sapient dinosaur species that had learned to make tools of wood, stone and obsidian - and bits of other dinosaurs. I based them on Troodon (because 1. those had unusually large brains for dinosaurs, and 2. they were omnivorous). Unfortunately, the setting was hard for me (at the time at least) to come up with good stories for.
I figured that an undiscovered dinosaur culture could make sense if they never made it to metalworking, and never reached a very large population.
