NixOS and Portable Executables

Were I to design a computer (both HW & SW), the founding principle should be compatibility with legacy code at no expense of performance or user effort.
Stuff like this gives me hope that I'm not merely wet-dreaming.

did you mean to say "wet"-dreaming in this context? Seems an odd addition to simply "dreaming"

Nah, the alternative that popped in my mind was "phantasizing", so I guess my wording aligns with my feelings. Whether these feelings are healthy is another discussion :D

The main reason I ditched NixOS was the missing ability to run dynamically linked executables by default and not wanting to deal with the possible fixes.
Good to See that there is hope for that.

I know it’s not a default, but `buildFHSUserEnv` is probably what you would have been interested in.

There is also `nix-alien` (I am the author BTW), that automates the process of listing all program dynamic libraries (as long they're not loaded at runtime) and creating the `shell.nix` file with `buildFHSUserEnv`.
And also `programs.nix-ld` now, that allow you to impurely include libraries available to all programs. It does some LD_LIBRARY_PATH hacks, but AFAIK it worked well enough for me when I had this in my system (I don't anymore since I barely run dynamically linked executable from other sources).

Thanks. Try `tone`[1] my pet project. I'm pretty sure it won't work without tinkering out of the box. Since I need a dev machine, that supports my FOSS projects, NixOS is not for me :-) BTW it was not the ONLY reason, I ditched it, but the main reason. There were a lot of nice advantages to NixOS, but they did not outweight the issues I personally had.

You ditched NixOS for the very reason it was created. Not being able to run binaries with missing libraries is a feature. The idea is to make you aware of your implicit dependencies, and to force you to make them explicit.
This makes me wonder if you were subjected to false advertising.

steam-run solves this for me at least.

Seconded. Despite sounding like it's only a tool for games, `steam-run` is very useful for generally running foreign binaries on NixOS. There's also `nix-ld`: https://github.com/nix-community/nix-ld

The font size and color and layout seems uneasy for me.

I'm trying to match the EGA colour palette for most if not all of my colour selections, and #555-on-#fff passes WCAG AAA requirements for body text. If I make it #000-on-#fff, I struggle to find good ways to differentiate inline `code` sections.
As for text size, the CSS expresses no opinion: I'm expecting your user agent to act in your best interest.
Do you have any suggestions?
The post title has been mangled, perhaps by the title simplifier. The "actually" in the title is important - the post is about Justine Tunney's work on "actually portable executables" (https://justine.lol/ape.html). Without it, it sounds like it refers to standard Microsoft "Portable Executable" (PE) format binaries.
