Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Ask HN: What Underrated Open Source Project Deserves More Recognition?
Cosmopolitan https://github.com/jart/cosmopolitan and https://justine.lol/cosmopolitan/index.html
Some genius realized that you can actually embed valid win32 programs inside valid posix shell scripts, and found a way to make a C cross-platform solution out of it, meaning that you can write C programs that compile to a single executable that will run on (quoting the site) Linux + Mac + Windows + FreeBSD + OpenBSD + NetBSD + BIOS
It all started from this post.

Show HN: Usr/bin/env Docker run
For this .args file, put one argument per line. This will run on start. You can use `/zip/mydepencency.anything` to read from files, but if you have an executable dependency you'll need to extract it first.
You can do this with any software you can compile with comsocc, by adding a call to LoadZipArgs[1] in the main function.
It'seasy to get started, your ideas will branch out as soon as you start playing with it.

Libwebsockets
FWIW there is ongoing work with good progress to add websocket support to redbean (https://github.com/jart/cosmopolitan/pull/967)

Actually Portable Vim (With a Cute Vimrc)
The binary was compiled with Cosmopolitan Libc [0], and therefore the binary will execute natively on Linux, Mac, Windows, FreeBSD, OpenBSD, NetBSD, and bare metal (BIOS boot).
I would call that portable.

Show HN: PyApp – runtime installer for Python applications
will go on my "to try" list where i already have cosmopolitan [2]. my last setup (windows) was shiv + wine + nsis (used that as pyinstaller had some issues)[2]

A standalone zero-dependency Lisp for Linux
Just compile regular Lisp with cosmopolitan. Then the same binary will run on windows, linux, mac, and BIOS. /s
This has been done with Lua, see: https://github.com/jart/cosmopolitan/issues/61

Cosmopolitan Third Edition
Cool. Somebody still needs to teach sscanf how to parse floats though. https://github.com/jart/cosmopolitan/issues/456
The code to do it would probably go in here: https://github.com/jart/cosmopolitan/blob/master/libc/stdio/...
I mean, I know why it's not done (parsing floats correctly is a lot harder than it would at first seem to be) and I'm not complaining, more like hinting to some of the fine people that haunt this website who might find such a task interesting.
There's so much cool stuff in this post.
https://github.com/jart/cosmopolitan/releases/download/3.0.1... is 213MB file which contains "fat binaries" (single binaries that execute on a bewildering array of hardware platforms and operating systems) for dozens of programs, including zip, curl, wget, python, ctags and even my own Datasette Python application!
It's absolutely wild that this works.
I just tried it out (on macOS). I downloaded and extracted that zip and did this:
cd ~/Downloads/cosmos-3.0.1/bin

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.
