Who even uses Erlang? I used Rails and then i tried Phoenix and it was lot more difficult to get things done. I don't understand Phoenix hype For solo devs, Rails is arguably most productive webapp system. LLM is very good at writing ruby rails code. Much better than writing django in my experience even though python training corpus is huge. I write my experimental apps in Rail when it stabilizes, i do a Go rewrite.…
You might want to update prod apps ASAP to this or the latest point version if below 29. Just deployed an app to production, automated security scans found 2 CRITICAL CVEs and half a dozen of HIGH risk ones dated Feb-May 2026.
Does anyone knows if WhatsApp is still based on Erlang?
I’ve been using Erlang since the early 2010s, right around the time we (the tech industry) discovered that WhatsApp was supporting over 400 million active users with only like 30 engineers.
I reached out to one of their engineers at the time (when I still lived in the US) who kindly responded to some of my questions via email. We ended up meeting for coffee and still stay in touch to this day.
I can tell you that Erlang is still very much a part of WhatsApp.

Is anyone still using Erlang for green field projects? I know there are plenty of Elixir enthusiasts here, I mean plain ol' Erlang. If you are still using Erlang, why do you prefer it to Elixir?

hello, would you please recommend a good resource to get started with elixir ? thanks for your time !
This is a good place to start: https://elixirisallyouneed.dev/resources

Elixir and Phoenix is a better production platform than Django.. I’m not throwing shade on Django, many production systems use it happily. I’m saying that Phoenix/Elixir is better, partly because of the BEAM and OTP and partly because of the language and the framework. Real concurrency. Better performance. Far more robust in production. The language is pre-compiled, and while not statically typed, that alone provides…
if you want true concurrency, why not use goroutines? It provides single binary deployment and static types?

Golang has its positives but you also lose a lot. Whole ecosystem is not comparable, like "debug live production cluster" is one-command away for Elixir vs "fuck you" for Golang

I was about to say "what, we've had records for decades" but then I read the changelog. Interesting. I wonder if there a world where Elixir starts compiling maps to "native records"?
probably not maps, but structs yes.
