Justine Tunney - Redbean and the Actually Portable Executable (Speakeasy JS, May 2021) - Despite the channel, this is about a C executable that "runs anywhere", including from boot (www.youtube.com)

Video is nearly 3 years old now, but I think it's worth watching. Her presentation starts at around 2:30.

Basically, she explains how Redbean, a tiny (~450kb) and very fast C http server, works and how the same executable can be used to deploy it on most operating systems (she starts explaining that around 14:30)

Justine is also the mind behind Sector LISP, Lambda Calculus in 383 bytes, considerable optimizations to LLamaAI, plus several other things.

I just tried the current redbean build on Linux AMD64, and everything worked as expected (both launching directly, and through sh). Which examples did you specifically try? Which sh version do you use (I have 5.2.26(1)-release (x86_64-redhat-linux-gnu))?

The cosmopolitan README has a section on the WINE thing, if you want to try and get it running.

I tried all of the examples from her page about αcτµαlly pδrταblε εxεcµταblε. It looks like the page was written in 2020, so I'm assuming the binaries were compiled then, but that shouldn't matter; I have Go binaries I built in 2021 that still run, and I have no doubt that it I could find an even older binary, they'd run too.

Those were their first tests, of course there is a high chance they won't run on all system configurations (especially since things like WINE comparability were likely detailed later). You should try artifacts built with the current version of the format (3 IIRC) if you want to give it a fair shot.

Good to know, thanks.
