This probably got second-chanced or something because I posted it over a week ago. Funny that this went up here since the follow-up is probably more in-depth.

Hope people enjoy it, both the technically interesting bits and the general goofiness of it all. I personally have enjoyed making the number go up.

I hope my co-fouunder on NervesCloud does some write-up on the allocator variations he has been trying. Every day he pops in and asks me to throw 5000 devices at the servers and see what they do. mimalloc, jemalloc and some others. Those two seem to do a better job with fragmentation for the BEAM than whatever we had by default, presumably from glibc.

Some ideas:

If you’re interested in an Elixir job then an acquaintance of mine has a site that might be a useful resource: https://underjord.io/jobs.html – there’s a mailing list there to get notified about Elixir job opportunities.

He also has a YouTube channel with videos about Elixir and other stuff: https://www.youtube.com/c/underjord

Also: On 2022-05-01 there will be new hiring threads here on HN. There’s always three threads: Who is hiring? • Freelancer? Seeking freelancer? • Who wants to be hired? So maybe just post in the who “Who wants to be hired” thread and see what happens? :)

Godspeed!

One use for this is using old android tablets as ambient display screens - you just autostart a browser on an mjpeg url and update the image to update the screen. Note that mjpeg doesn't have a frame rate - it just renders the frames as they show up, so you don't actually have to keep sending them when they're not changing... except that chrome is buggy about not actually rendering the image right when it shows up :(

(I did a version of this in bash with netcat, and here-documents for the mime parts, which is where I ran into the problem. https://underjord.io/live-server-push-without-js.html was the inspiration for the display-screen case...)

Background to the article: https://underjord.io/unpacking-elixir-iot-embedded-nerves.html

Seems like they deploy Elixir on embedded Linux. The embedded Linux distro is Nerves which replaces systemd and boots to the BEAM VM instead as process 1, putting Elixir as close to the metal as they can.

I know nothing about any of the above (assumption is I'm fool enough to try and simplify) plus I know I've misused the concepts I wrote but that's my point so read the article. All simplifications are salads

Windows has been going out of its way to be hostile to users for over a decade now.
