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.

How could the early Unix OS comprise so few lines of code?
Not only early Unix; look at the original inet_addr implementation [0]. It accepts not only "0x" but also just "x" as the 16-base prefix, it doesn't really care about the numbers overflowing, and it parses 09 as equal to 011 (which is decimal 9). And the less said about the coding style, the better.

Backward Compatibility, Go 1.21, and Go 2
No need to guess. My man page for inet_aton says it comes from 4.3BSD: https://github.com/dank101/4.3BSD-Reno/blob/master/lib/libc/...
The earlier inet_addr from 4.2BSD has the same logic: https://github.com/dank101/4.2BSD/blob/master/lib/libc/inet/...
inet_aton and inet_addr parses addresses the obvious way. Using something like strtoul or especially sscanf would be stilted. The beauty of C pointers is that it makes simple parsing tasks very easy--perhaps too easy.

There is no such thing as a “glibc based alpine image”
It probably made sense in 1983.

Python Is Portable
The reality is a bit different, the work on Python 3.6 was checked into the Cosmopolitan repo and I have been able to use it for production workloads that are in pure python. [0]
As Cosmopolitan Libc has evolved, it has been possible to compile more software without modifications, and that includes latest Python through a project called superconfigure[1].
Last person who tried to reproduce it from scratch did it last week (granted it too them a few days of solid work) but in the end they ended with a portable binary with Python 3.11.9, brotli, ssl and asyncio for their work related project.[2]

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.
- Cosmopolitan – build-once run-anywhere C library
-
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)

Ask HN: ANSI escape sequences reference docs?
Check out this comment by jart (cosmpolitan author) here: https://github.com/jart/cosmopolitan/issues/766#issuecomment...
it might help but not sure how comprehensive it is! would it be a bad idea for you to check out the source code of other popular emulators (maybe iTerm 2^0) ?

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]

src - Read-only git conversion of OpenBSD's official CVS src repository. Pull requests not accepted - send diffs to the tech@ mailing list.
official-images - Primary source of truth for the Docker "Official Images" program
SDL - Simple Directmedia Layer
robovm - Ahead of time compiler for JVM bytecode targetting iOS, Mac OSX and Linux
llvm-project - The LLVM Project is a collection of modular and reusable compiler and toolchain technologies.
Codename One - Cross-platform framework for building truly native mobile apps with Java or Kotlin. Write Once Run Anywhere support for iOS, Android, Desktop & Web.
luastatic - Build a standalone executable from a Lua program.
v - Simple, fast, safe, compiled language for developing maintainable software. Compiles itself in <1s with zero library dependencies. Supports automatic C => V translation. https://vlang.io
