I see the alpine and python:3.12-alpine images in your cli docs. Where does these come from?is it from a docker like registry or are these built in? Can I create my own images? Or this this purely done with the smolfile? Is there a Ubuntu image available?

Looks really nice btw. Hot resize mem/cpu would be nice. This could become a nice tech for a one-backend-per-customer infra orchestrator then.

Wonder what you are thinking of then?

there is TabPFN [1] which also has time series capabilities.

i have this in my .zshrc which provides same functionality:

  lk() {
    if [ $# -eq 0 ]; then
        local output=$(sudo lsof -iTCP -sTCP:LISTEN -n -P)
    elif [ $# -eq 1 ]; then
        local output=$(sudo lsof -iTCP -sTCP:LISTEN -n -P | grep -i --color=always $1)
    else
        echo "find and kill processes listening on ports. Usage: lk [pattern]"
        return 1
    fi

    if [ -z "$output" ]; then
        echo "No listening processes found."
        return 0
    fi

    # Show header + results
    echo "$(sudo lsof -iTCP -sTCP:LISTEN -n -P | head -1)"
    echo "$output"
    echo ""

    # Extract unique PIDs (skip the header row if no grep was applied)
    local pids=($(echo "$output" | awk '{print $2}' | grep -E '^[0-9]+$' | sort -u))

    if [ ${#pids[@]} -eq 0 ]; then
        echo "No PIDs found."
        return 0
    fi

    echo "PIDs to kill: ${pids[*]}"
    echo -n "Kill these ${#pids[@]} process(es)? [y/N] "
    read -r confirm

    if [[ "$confirm" =~ ^[Yy]$ ]]; then
        for pid in "${pids[@]}"; do
            echo "Killing PID $pid..."
            sudo kill -9 $pid
        done
        echo "Done."
    else
        echo "Aborted."
    fi
  }

I have added quite a lot of functionality beyond listing and killing ports. Please check out the readme, it may convince you to try it out.

HN is a place where people can be expected to go beyond the title (though I like the limited script and am glad it was posted). Misleading titles are not uncommonly flagged and changed, even.

True, it was what it started as, but grew as i found my self missing features. Got a few users and now i don't want to update the name. Also easy and quick to write in the terminal

Do you do something similar to the modifications codesandbox has done to firecracker, regarding mmap ram? (They have multiple blogposts about it on their blog)

Would love to chat about details there

I have read about it, but currently using vanilla Firecracker w/o any memory optimizations. It is as simple as it gets for now

How does it compare to tabpfn?

Limix outperforms tabpfn v2: https://arxiv.org/pdf/2509.03505

Is this compatible with the dx dioxus cli? Would love to have a cache layer for it

We haven't worked with Dioxus in particular, but the CLI is a project that we benchmark against: https://github.com/attunehq/benchmarks

Sounds interesting, do you have any links to these projects? Could not find multicardz when searching

I am dark at the moment.

I am doing final testing, packaging, integrating strip, etc. My target was before end of month. If I work hard I just might make it.

I'm releasing a bunch of things at once: 1. multicardz.com 2. a paper on using DOM as single source of user state dataos.software 3. an OSS repo of hyper performant implementation of that for React (stateless.software) 4. an OSS repo that might best be described as Tailwind for frontend behavior. (genX.software)

they are all somewhat interconnected

Yep!

Oh and there is flok[1] which combines the strudel repl with visuals from hydra. Also there are sclang and other algorave environments available. Everything is synced (with crdts i guess) so it’s live collaborative. Which is nice to remotely jam with friends

You can also use hydra in the standard strudel repl, and vice-versa.

And quite new dilber.io: https://github.com/Omodaka9375/Dilber

Also Gibber: http://gibber.cc/

How is the performance of the mounted host directories? It’s some file server over vsock?
