dietlibc VS cosmopolitan

- Dietlibc: https://www.fefe.de/dietlibc/

The commercial success of a product totally depends on the business model you come up with, whatever be its opensource (or not) license.

Corporates have a vested interest in promoting the propaganda that only a non-xGPL opensource license can be commercialised successfully simply because they cannot freely steal the source code of a competing xGPL licensed software.

The real value of an FSF license, like the AGPL, is that it was designed to protect the copyright holders, and its users, "right to repair". And thus, it cannot be closed source by anyone (apart from the original copyright holders) once released under the said license (even if future versions are closed source, the old version under xPL remain opensource perpetually). Other open source license (that are less stringent) are prioritised to increase developer contribution. Source code under such license can be closed-source even from the original copyright holder.

But again, commercial success totally depends on the business model you come up with, irrespective of your license. The right license and the right business model will empower each other. Or cripple your business.

There are definitely some nice alternatives to glibc out there. He mentions Cosmopolitan Libc. I've used musl, uclibc, and dietlibc/libowfat in the past.

Maybe you should include the math part of a libc statically with your code. glibc is one option, or dietlibc if you want it to be as small as possible.

I agree that the implementation of printf is complex, but the interface is not. Hence calling it should not introduce bloat. Glibc adds a bunch of constructors and tables and such, whereas linking with dietlibc will probably lead to a smaller executable.

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]

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.

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.

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

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) ?

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.

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]
