Erlang: The Movie

Demo of the Erlang programming language
Ericsson
Migrated from my Google Video account.

[@blnm]

my left ear enjoyed it

[@bhupeshimself]

Lol 😂 i thought i broke my headphones

[@ruhnet]

After several minutes of turning Bluetooth off and on, headphones power switch off and on multiple times, messing with volume, etc., I was relieved to read your comment. (I only had the right earpiece in my ear...) 🤣

[@antekone1]

Thanks for the comment. I've started hitting my speaker because I though it's dead. Now I'm telling it that I'm sorry!

[@Nehpets94]

RIP Joe Armstrong. I've been digging into Erlang and Elixir and I'm in love. Thank you for your contributions.

[@rahultrikha]

Kind of funny that some languages still struggle with concurrency and these guys had it sorted ages ago.

[@keyhanjannatkhah6729]

and have been solved 4 decades ago by erlang

[@denvaar]

Love when he's like "Managed to fix a bug, eh? *hangs up*"

[@mwgkgk]

The hotswap example still impressive in 2016

[@bkboggy]

Yeah, I was pretty impressed that it did not disrupt the call.

[@chrisE815]

I was a bit confused by that: at ~ 8:27 he says "restart the system." How could a restart occur without dropping the call?

[@mwgkgk]

@@chrisE815 Perhaps an Erlang expert can provide actual insight, but I believe that it's just them re-starting some custom initialization that has to occur before the new experiment can take place. It's just them issuing the "run." command within the repl, the actual BEAM process is not restarted. Can agree that it does sound confusing. The hot-swapping is meant to work within the live process.

[@radoznalipustolov2693]

@@chrisE815 It's a feature of the BEAM virtual machine on which Erlang programs are executed. VM will make sure that all processes are still working even in case one fails (processes are isolated). This way it will prevent error to propagate through entire system.

[@guillermogutierrez710]

Still impressive in 2022

Hello Roberts, Hello Mike, Hello Joe

Hello World!

[@user-dz6il2bx5p70]

tbh this is one of the best videos about a programming language

[@gabydewilde]

This is the video about the programming language.

[@ryanleemartin7758]

I love these kind of old tech videos so much. I don't exactly know why.

[@edmaphis9805]

[@owenliang1990]

still feeling cool in 2020, erlang goes far ahead in that year.

[@Randemonium]

This is the greatest movie I have ever seen.

Emacs and X, sounds like the present to me.

[@ScottZiegler]

Hello, Joe. Goodbye, Joe. :(

[@jimedgar6789]

I was sooo waiting for the Spanish Inquisition to storm in.

[@lazykid9167]

:D

[@adamroberts1338]

I enjoyed the constant switching between "Roberts" and "Robert"

[@NurMarvin]

RIP Joe Armstrong

[@cyphen21]

I do not regret watching this at all.

[@hannessteffenhagen61]

Interesting how you can still see the roots in Prolog here in the tools and terminology used, even though the actual Erlang language isn't really anything like Prolog.

[@atn_holdings]

Twist ending at 9:20 This is just masterful cinema

[@RondoDondo]

Goodbye, joe Rest In Peace

[@cuma212]

as someone who is starting to work in erlang (maintaining legacy code) is truly interesting

[@RodrigodeOliveiraFernandes]

Most epic intro sound ever.

[@someone7554]

I love how triumphant the intro is

[@productiveelixir3113]

Summary: To build real-time distributed systems we realized that we had to move from imperative languages to a declarative language. This led to erlang being born. Properties of declarative languages: Programs are shorter. They encourage a clearer programming style Declarative languages are symbolic. We had to add the notion of concurrency and real-time to Erlang as declarative languages at the time didn't have this. We also added error detection, this allows to program robust real-time systems. [When using the telephone...] An error in one call will never affect other calls. (Parallel processes) A large scale experiment in Ericcson led to the finding that: programming in Erlang leads to at least a factor of 10 in increased productivity. Erlang programs are concise and elegant, they are 7 times shorter than equivalent programs in C.

[@Doww1e]

This movie belongs in a museum! (spoken in Harrison Ford voice)

[@dlekic]

After so many years as C++ programmer, I wish I learned Erlang instead of C++...

[@carlerikkopseng7172]

Not too late 😊 These guys had programmed C++ too.

[@grahamm7408]

It’s refreshing to watch programmers being dignified, a stark contrast to the brash and overly opinionated programmers of today

[@pauljohnson-yk5dq]

A classic intro to a great programming language!

[@timljensen]

Joe's segment starting at 1:10 reminds me of John Cleese from Monty Python's Flying Circus.

[@AdolfoNeto]

This video is audio parallel! The left audio channel does one thing and the right audio channel does another!

[@AlfredReinoldBaudisch]

What a coincidence that you are here today as well. I was convincing some more people about Erlang and came here (again). Each audio channel runs in a different Erlang process.

[@cthree87]

best video evar.

9:34. Very impressive Erlang...

[@wikigrinder]

This is the cheesiest promo ever made about software XD Btw, I'm learning the language right now (as a hobby language next to the C# I use for work).

[@slaction]

It would have been a lot cheaper to do this video with actual human beings rather than robots.

[@pmarreck]

You've seen the sequel, I presume

[@Paxoification]

Goodbye, Joe!

[@PerriPaprikash]

I think using someone's name during a conversation when you're already familiar with them is a bit passive aggressive especially so for erlang developers. "Hello Joe ... Hello Mike"

[@brucetate839]

Goodbye Joe.

[@Sando816]

RIP Joe! great computer scientist!

[@zhuweiyang1047]

Anybody knows when it was recorded?

[@JPMeijers]

Dit lyk vir my baie na 'n episode van Monty Python :)

[@Ichinin]

According to this video, people who coded in Erlang died from boredom.

[@dmitriid]

Compared to anything that doesn't have built-in support for distributed/parallel processing, process linking, error handling across process etc.

[@carlerikkopseng7172]

What other languages/environments have that built in? Not JVM or CLR, AFAIK?

[@tunmie.o]

i think this is my cue to dig in the BEAM ecosystem

[@ThePandaGuitar]

[@Archie3D]

I can clearly see that something has gone wrong here.

[@Yetipfote]

He was responsible for THE computer science laboratory.... everybody knew which one because there was only one on the whole wide world back then.

[@JesseWarden]

"high level languages like C++" LOL, history is awesome

[@graspee]

c++ IS a high level language.

[@JesseWarden]

"os independent, more human readable" per Wikipedia == Wikipedia is talking about brainiac, uber smart math people who can read C

[@koshu4]

Hardware engineer: "High-level languages like C". Applications developer: "Low-level languages like C".

[@konstantingeist3587]

C++ is both high level and low level in one package. Template metaprogramming as as high level as you can get.

[@GuilhermeTrojan]

yeah, oop is definetely not high level

[@robertkielty5094]

[@jacobkhan1237]

When was this video made

[@wind1309]

i love watching this movie

[@moritzmayer9436]

the same for the atom run, has there anything change in the core system of erlang?

And of course... it's still a better love story than Twilight.

if your programming language doesn't have a demo like this it's not a real language

yeah nobody writes programms in Erlang.... wait isnt CouchDB, SimpleDB and WhatsApp written in Erlang? ;D

Compared to hacking their PABX switches in assembler, most likely. But it sounds good.

“Programming in Erlang leads to 10× increased programmer productivity” ← Compared to what?

[@urbankoistinen5688]

Compared to C++.

[@St_Joe]

I heart this.

[@wihlke]

Hehe, yeah it's used everywhere. And I love it. I also love C though and C++, both of which are extensively used. Yet, you cannot argue they're not very up to date.

[@garychap8384]

I loved this all Aspie production about Erlang. The Monty Python intro was fine enough, but the Sado-Masochistic Alpine outro was absolutely sublime. On the negative side ... and speaking as an Aspie myself, I found the dramatic and overly-emotional presentation a little distracting, and feel that the presenters could have been a little less excitable and dynamic in their delivery, as this sometimes got in the way of the message. Nevertheless, I've mulled it over and I think I'll stick with Haskell for my particular functional/declarative software needs.

[@WhileTrueCode]

This all seemed great until I realized there was like 1kb of log to process 3 bytes of data. And I thought web programming was bloated

[@hansmuller1625]

You didn't stop to think that all this was run in debug mode, and not an actual production setting?

[@pmsorhaindo]

too hardcore!
