Does this work for platform/architecture independent docker images? I tried a little with the python universal binary, but I think the CMD line would be platform specific?

  Dang may correct me on this. But it isn't a Dupe if the other one hasn't reached front page.

    It's a woolier 'significant attention' but things like 'two comments' or 'never on the front page' tend to count for undupeness. https://hn.algolia.com/?dateRange=all&page=0&prefix=true&query=by%3Adang%20significant%20attention&sort=byDate&type=comment https://hn.algolia.com/?dateRange=all&page=0&prefix=true&que...

  That post is the release link on GitHub, while this is the announcement by @jart on X and a showing of performance gains in GitHub Actions CI I found the performance gain to be significant enough to be interesting and so I posted.

Does Cosmopolitan support Android yet? It would be nice to have an alternative to the NDK
- stylepoints 3y ago
  If I am correct in my understanding of how it works, Linux versions should work on Android as well.
  - KRAKRISMOTT 3y ago
    Android is kind of a special child, it uses custom kernel modules like Binder (IPC framework) and Ashmem (Android's garbage collector/memory manager).
  - matheusmoreira 3y ago
    The Linux system calls used by cosmopolitan work fine on Android provided they aren't blocked by seccomp policy. Some of those blocks make sense, others not so much. Yesterday I discovered I could use all the stat variants but not statx. I believe the features provided by standard C libraries are well covered by the set of allowed system calls.

  A few weeks ago I tried building cosmopolitan inside a Termux environment but the makefile didn't like it. At the time I gave up and used my laptop because I was focused on developing a feature. I wonder if I could get it to work now.

What’s the use case? I have mad respect for cosmo & what technically it’s accomplished. But I also haven’t figured out the problem per se it’s solving. I’m genuinely curious to hear how others use cosmo.

  Build once against a universal libc layer, and produce universal binaries which run on a variety of different architectures and operating systems. It’s like LLVM or JVM but even for C, and without the overhead of virtualization. (Hope I did it justice I am merely a fan)
  - skybrian 3y ago
    Yes, but who builds binaries this way and what do they use them for?
    - jhardy54 3y ago
      Python wheels are one use-case I’m excited about.

      Honestly - CLI apps that need to run on multiple platforms. I once built a version of https://github.com/lovebrew/lovebrew https://github.com/lovebrew/lovebrew (back when it was written in Nim) using Cosmopolitan 2, and I got back a single binary that ran on all major operating systems. This greatly reduces the time GitHub actions would need to run, as you just build and release for one OS. As others have mentioned, this does not really work for native GUI apps, that isn't supported by Cosmopolitan as far as I know. But for small CLI tools it works great!

Neat, they also launched a repo for these universal binaries [0]. It took a little digging, but the list of binaries are here [1]. Might be useful for a universal install script? 0: https://cosmo.zip/ https://cosmo.zip/ 1: https://cosmo.zip/pub/cosmos/bin/ https://cosmo.zip/pub/cosmos/bin/

Oops they did it again! Massive fan, and I use it!

Using this, is it possible for live running application state on one device to be sent to another device, esp if running a different OS?
- paulclinger 3y ago
  No, to my knowledge cosmopolitan doesn't provide any special provisions to support this, so you'd have to build it yourself.
