Nolibc: A minimal C-library replacement shipped with the kernel
Seems unlikely. My spot check of the the two vfprintf implementations shows no flow from one to the other, and shows that part of the Cosmopolitan code has an older lineage than nolibc.
The nolibc source has many reference to copyright held by "Willy Tarreau", under LGPL-2.1 OR MIT license, with a copyright date starting in 2017.
The string "Tarreau" does not exist in the Cosmopolitan library, so that's a strong negative there. Let's look closer.
The file organization is quite different. And so is the implementation. So that's another negative.
Compare the vfprintf in nolibc at https://elixir.bootlin.com/linux/v6.2-rc4/source/tools/inclu... (a 'minimal vfprintf()') with the one in cosmopolitan starting at https://github.com/jart/cosmopolitan/blob/master/libc/stdio/....
Right away we can see nolibc places many functions in the same file while Cosmopolitan uses a one-function-per-filename organization.
Cosmopolitan's fvprintf locks the file (which nolibc doesn't need to do) then calls vfprintf_unlocked which calls __fmt at https://github.com/jart/cosmopolitan/blob/master/libc/fmt/fm... , which is the actual implementation. It look very different from NOLIBC's.
Okay, so perhaps that's they way now but not at the beginning?
We can also go back to Cosmopolitan's original implementation and see how vfprintf goes through https://github.com/jart/cosmopolitan/blob/c91b3c50068224929c... to call "palandprintf", which https://github.com/jart/cosmopolitan/blob/c91b3c50068224929c... says is copyright "Marco Paland" from 2014-2019.
That's a few years older than the start of nolibc, available from https://github.com/mpaland/printf , and part of https://github.com/embeddedartistry/libc , a "libc targeted for embedded systems usage".
Thus, multiple factors seem to agree that nolibc code is not used in the Cosmopolitan library.

Ask HN: Resources for Building a Webserver in C?
Here's a 2000 line web server written in C that runs https://ipv4.games/ which you can read at https://github.com/jart/cosmopolitan/blob/master/net/turfwar... This web server runs on a single VM. It was handling about 300 requests per second earlier today. You can monitor its metrics here: https://ipv4.games/statusz It uses *NSYNC as its multi-threaded locking primitives, which was designed by the guy who created Google's lock server.

Is there a standardportable C library ?
cosmopolitan though still a work in progress (last time I checked, its scanf() could not parse floats, for example.) But even more amazing, with actually portable executable not only the same code, but the same binary will run on linux, mac and windows (on x86_64).

Rust and C++
Because operating systems have been using different executable formats for decades. That's a trivial implementation detail. To the point that you can build universal binaries with https://github.com/jart/cosmopolitan (though I wouldn't use this for anything serious).

AT&T Syntax versus Intel Syntax
AT&T syntax is the most elite syntax. I've used it to write some famous hacks, like Actually Portable Executable. What makes AT&T syntax so powerful is its tight cooperation with the GNU linker. I don't think it would have been possible for me to invent APE had I been using tools like NASM and YASM. https://github.com/jart/cosmopolitan/blob/master/ape/ape.S

Dozens of malicious PyPI packages discovered targeting developers
Indeed! If your dependencies are able to be command line programs that are shell scripted together, then you can in fact have an access policy on a per-dependency basis, using my pledge.com tool. So shell scripters of the world rejoice.
But it gets better. If you build python.com in the Cosmopolitan Libc repository:
