Cela fait quelques temps que je n'ai pas publié sur Masto. Ça bosse dur mais sortir des résultats prend son temps... En attendant, j'interviens jeudi prochain dans le Séminaire d'hiver du collectif #EPSI
pour parler #ingénierie et enjeux de l'expertise technique dans le mouvement #lowtech, en compagnie de Marie-Pierre Escudié, qui parlera d'informatique #frugal avec le cas de #CollapseOS.

I love #collapseos but this might be an even more durable post-collapse option...

The problem with the emulation approach is that it makes dropping down into native code harder. In #CollapseOS and #DuskOS you can write a word in native code and have a fallback definition in portable Forth that only activates if there is no native version.
With an emulated ISA (this also includes #uxn) you either use macro-ops (becomes complicated for large functions, how do you catch memset?) or you extend the ISA (see devices in uxn).
This is kind of a cursed idea, but could something like #CollapseOS or #DuskOS run entirely from the CPU cache with no DRAM if one hacked it directly into the #BIOS?
Mastodon is the best way to keep up with what's happening.
