Ideally websites just respect the existing media queries so you don't even have to switch!

Yeah. You'll notice that there's a mix of light and dark. Some segments are light-on-dark, then it switches to dark-on-light. It appears to me like a "design trend" that's at odds with accessibility. https://www.apple.com does this too.

Boom! Fixed, thanks!

I'm hoping to find a reason to use it soon.

Do you have a program that doesn't need to run fast?

Reading the Erlang ProgProgrammers book by Joe Armstrong made me a better Ruby programmer as it changed my perspective on functional programming and abstractions.

I first reached for Elixir when Ruby couldn't handle large amounts of websocket messages. It really shines in high-concurrency contexts. I also love Phoenix LiveView and have a couple of side-projects running on it.

its been fun building a multiagent personal assistant.

(wip, no guarantees, this is the engine i use)

Such a delight to use and the core team seems to always make the right decision.

I think most will agree that it improved on Erlang.

For me as a long-term ruby user, though, elixir is not quite as elegant as it could or should have been. Even simple things such as "defmodule Xyz do" feels weird to me.

Thankfully you were here to make sure we didn’t forget about it for even one post

They have a Machine Learning section on the front page. Just have to scroll down a bit, under the "Use Elixir for" section.

But I bet the landing page was made with AI assistance.

In fact it came out as the absolute best in a comparison by Tencent (1). See table 4. It’s more than a year old though.

There are multiple people working on the JIT within the last 5-6 years. The WhatsApp folks also contribute meaningfully.

I suspect once the Erlang/OTP team squeezes all performance in the JIT, they will look into optimizing across modules, which will probably open up many new possibilities, but it requires rethinking some runtime primitives.

It’s pretty hard to make things like math faster for real world use cases in a bytecode interpreter.

It should be fixed soon (deploying now). Thank you!!!

It's been a while, but I used to work at WhatsApp and we used Erlang distribution heavily. I understand the clusters have gotten really huge since I left.

It's super handy. There's no security barrier between nodes. It's a headache if your network is unreliable.

For a chat app, messaging someone becomes a series of steps:

a) look up if they're online (send a message to the presence database service)

b) if you got a process id back, that's the process connected to the user, so send it the message. The process could be on the same machine or not, but the sending api is the same. This is the special part: few other environments make arbitrary messaging between processes/threads/tasks/whathaveyou so pervasive.

c) if you don't get a process id back, the user is offline; send the message to the offline database.

Also interested in hearing about this! I built an elixir k8s control plane recently and kept expecting to reach for it but it never really made sense when it was controlling golang daemonsets.

My usecase is less independent though, that control plane is orchestrating like Lambda/fly.io style workloads on top of firecracker: https://jomcgi.dev/ember

I've worked a little bit with distributed Elixir using `Horde.DynamicSupervisor` on Kubernetes. Apparently there's other options like 'swarm' and DynamicSupervisor [1]. It'd be great for clear analysis of the benefits these kinds of abstractions bring vs non-BEAM approaches.

Elixir/Erlang works very well in a semi-embedded environment where you need a higher level command and control component that behaves in a deterministic way and is pretty robust.

I was involved, years ago, in using Erlang on these devices: https://www.icare-world.com/us/product/icare-eidon/

It was a lot of fun and there were some very interesting challenges for everyone involved.

That's a good point. It is meant to be an introductory example but I will see if I can come up with something else! Thanks!

EDIT: shipped!

It also does not load if Javascript is blocked.

> appreciate Elixir but the problem is the job market/talent pool is tiny compared to other existing languages.

> I shipped an entire telecom infrastructure with barely knowing Elixir and we brought on contractors to audit the code and they found no issues.

Erlang/Elixir experience is rare, because it's not widely used and the teams are small. It's not worth trying to hire for it. Hire for people who can figure it out on the go (amd are willing to give it a try).

You did it, hire other people who seem likely to be able to.

If you vibe coded an entire telecom infrastructure and an external audit found no issues then it sounds like you might need to find better auditors.

i hired a biologist (for my pharma startup) and she produced feature ideas for our internal stack and was guiding claude to write idiomatic code with feedback from my reviews with no coding experience. realistically if you want to start an elixir company today you need one consciencious senior that likes code review and any number of juniors with minimal competency and sufficient curiosity.

Can you clarify which ones? We will be glad to improve them (or feel free to send a PR).

Maybe try and build something and see for yourself? Saying elixir is not fit for real world use shows how little experience with it you have.

Have you tried it since the new type system rolled out?

> not suited for real world use.

I hope you don't use discord or rely on pagerduty.

The Software Mansion folks designed it and we actually iterated on the designs on Figma, having discussions as humans, and exploring alternatives. They were lovely to work with.

I also worked on all of the copy myself, collecting feedback from core maintainers as I went. The new tagline was a suggestion from Theo which we iterated on. I did use LLMs as an assistant, but I did not ask it to generate the content.

Might as well use LLMs for the whole thing next time, since we will be accused of doing so anyway! :D

This is how every second website has looked for the past 10 years.

Its pretty snappy/responsive for me at least so thats good. Normally LLM slop sites are pretty at first but sluggish as hell. So some level of skill went into this one.

Such as?

How is this language related to Elixir? Or are you just commenting that another language has a website?
