Just in case anyone hasn't seen the old classic, Erlang: The Movie

This is the same "movie", but the audio has been fixed to not play out of just the left ear: https://www.youtube.com/watch?v=BXmOlCy0oBM

Like on a telephone :)

Hehe, shame this got down voted so much. It's actually a pretty hilarious Erlang joke. They made a video way back showcasing Erlang in the setting it was primarily used: telecom systems. In this video they keep calling and greeting each other. The video can be found here: https://www.youtube.com/watch?v=uKfKtXYLG78

This is the original video in its 90s glory: https://www.youtube.com/watch?v=uKfKtXYLG78

Regardless of where the call is handled, you can't just deploy a new switch in a telecom network, but you still want to upgrade them. This is where you really want hot code loading.

Real world usage case - I have a server which handles several thousand telematic devices (telemetry+actuation), split into about 20 different device types. It's small device base so doesn't require multiple servers and we can be really cheap. But requiring to disconnect all devices just to make one small change to one device driver would be painful. Now we can have uptime of over half a year and in that time we had changes/fixes to several drivers. Normally that would require scheduled downtime every week and slow us down considerably.

Spawning a process for each call / endpoint is how almost every large phone switchboard does it. See also: Erlang The Movie:

In deed this has been suggested to me by other people (of course _after_ discussing above software with them :). Yet I believe siproc still has a few benefits to offer, most notably not having to set up/build a full PBX to run it.

Who uses Erlang in telephony besides Ericsson?

⬐ detaro

AFAIK Motorola does (did?) too.

⬐ vertex-four

Erlang's definition of a process is a much lighter weight than Linux's, though.

They should have used Erlang https://youtu.be/uKfKtXYLG78

I wonder what coused this issue? Dependency issue in Maven? May be they cannot figure out what that Java error means?

Repost, but I can't find a previous thread with much discussion.

I rewatched this so many times: https://www.youtube.com/watch?v=rRbY3TMUcgQ

⬐ vaylian

For context: This is the unofficial sequal to the official Erlang movie. Updated for people from the future. Definitely worth a watch.

⬐ davidw

Many of his videos are worth a watch:

https://www.youtube.com/user/gar1t/videos

The 'MongoDB is web scale' one is pretty funny and was widely watched shared in the day.

I wish he'd make some more videos.

⬐ avip

"Declarative vs. imperative debates are always a crowd pleaser".

Thanks, great link.

⬐ tim333

Thats the one that stuck in my mind. (spoof edit of the erlang talk)

⬐ pmarreck

This will be incredibly funny for certain people (like myself)

⬐ usermac

"...I'm interested in what the little girl has to say" OMG that line made me laugh out loud. thanks for sharing the link.

⬐ andrewchambers

Goodbye Joe

⬐ Carpetsmoker

I will never understand why Armstrong didn't pursue a career in acting.

⬐ spiralganglion

I enjoyed their telephone etiquette so much that I made this re-edit last summer: https://www.youtube.com/watch?v=UuSZ37vMIks

I had never watched Erlang the Movie before, this is truly a gem:

https://www.youtube.com/watch?v=uKfKtXYLG78

This is a great way to explain the benefits of Erlang. Anyone who has tried to write robust, distributed systems should immediately see the benefits. Even all of these years later.

⬐ francescoc

I use Erlang the Movie and its Sequel https://www.youtube.com/watch?v=rRbY3TMUcgQ&t=9s whenever I teach my classes at Oxford Uni. #studentlife :-)

⬐ pmarreck

You caught the advancing of the movie to the 9 second mark in your URL. (I can't stand when youtube does this automatically, such as when adding videos to playlists...)

⬐ jimbokun

Genius.

⬐ davidw

I dearly wish he'd make more videos. I also loved 'MongoDB is web scale' - https://www.youtube.com/watch?v=b2F-DItXtZs

Their original video demo of hot code swapping is also a classic worth checking out:

https://www.youtube.com/watch?v=uKfKtXYLG78

That got a lot of programmers interested in Erlang ~10yrs ago.

And, after you've watched the original, check out "Erlang The Movie II: The Sequel", by Garrett Smith (aka gar1t): http://www.youtube.com/watch?v=rRbY3TMUcgQ

(You are likely familiar with one of gar1t's earlier videos, the classic "Mongo DB is Web Scale":

http://www.youtube.com/watch?v=b2F-DItXtZs

And he's got more on his YouTube channel: http://www.youtube.com/user/gar1t )

That is, until someone shares Erlang: the Movie [1], then it is game over.

Just a quick way to join in on the Erlang goof this afternoon.

This video is meant to be serious, but the hokey opening music and deadpan dialogue and expressions make it seem like a Monty Python sketch.
