primes-cpp VS cosmopolitan

Everybody mentions this, and what's great is that it is a pretty natural solution to a lot of problems. I remember coming up with a version of it while writing an optimized prime-sieve[1], and was surprised when I later learned that it was some named technique.

In addition to just the basic loop-unrolling (which I'm pretty sure you usually don't need to do by hand with modern compilers), it works really well when you need to jump into the middle of a pattern. Like if you're sieving primes in a wheel-factorized array.

  // Here we're only checking possible primes after wheel-factorization

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]
