In many ways the AWS spend slash can be explained by the @sasajuric list extending to machine learning with Nx and Axon. This was the enabler. Then OTP and the amazing tools on top of it (like Broadway!) gave us what we needed to move from Prefect and Spark. #myelixirstatus

With FLAME, instead of fitting the BEAM on infra, you're building infra with the BEAM. This is a bigger shift in terms of architecting than I gave it credit for. It's not just lambdas. Rebuilding our ETL with it now and I feel like a wizard. Back to the monolith! #myelixirstatus

@thmsmlr @danielberg_ @PJUllrich So what I'm saying is that this kind of garbage isn't an 'irreverent' culture. In fact, it just entrenches power dynamics, which is kind of the opposite of irreverence. Being a little edgelord in your privilege doesn't make you irreverent and shouldn't be excused as such.

So @sasajuric 's famous chart adds machine learning to it, and if Rails is the 'one person framework', then Phoenix is the 'half person framework' from CRUD to the cutting edge of LLMs. ML in Elixir is 'production ready', yes. In this ecosystem, that statement means a lot.

OTP is just completely unique. Phoenix (and LiveView) have this baked into their core, and it reaches all the way up to the client, where LiveViews are 'just processes'. There's no better stack for building AI-powered SaaS, even if you don't use Elixir for the AI part.

There's still some work to be done in the way of providing precompiled artifacts but... Metal support for Nx is here! contains a working example of how to run Nx functions on NxIREE. Many thanks to the IREE team who've helped a lot in the past few months

With Oban, it's crazy easy to just replace where we were embedding before with an enqueued job that is _durably_ scheduled at midnight that night.

The actor model of concurrency is the right abstraction for serving ML workloads (models in processes). And because it's all built-in, you can take advantage of everything else that makes the ecosystem great. Nx.Serving is just another application in your supervision tree.

Just another example of how Elixir is a cheat code. The level of polish, reasonability/maintainability, performance... it all comes with so little work. LiveView means I can go from idea to customer-facing on a feature like this as a single dev in a couple of hours.

And this is the beauty of it. Because you're working in a system like that, you can create absolutely brilliant features for your end users with minimal effort. We're throwing around thousands and millions of messages a day over pubsub, between processes, etc.

I just hooked up my new app to use Tigris on @flydotio and I'm blown away. So simple to get going with! 15 minutes later I have end to end file upload in my project ready to go. I didn't even have to login to AWS 😭❤️ Wow. #MyElixirStatus

Those hiccups above were due to overloading our database connections. This has smoothed out a bit. Still working on maximising throughput, but getting there!

So as someone building a product, you can focus your creativity on solving problems for your customers -- not solving all these problems related to concurrency that have already been solved by Erlang/OTP years ago.

@nileshtrivedi I don't see why not. I think it would be very straightforward to push generated components. Some of the pieces might be or and then just some simple LiveView.

What's the best practice for relatively big files in tests with ExUnit? For example, I've got a fair few long (500k-2mb) XML files I want to run parsing tests against. Something like /test/support/fixtures/*.xml? #myelixirstatus

This is how we do real-time collaboration in Amplified. Everything is happening with pubsub. Asynchronous expensive work like search is happening in Oban and broadcasted out. Every change to the project in the db is broadcasted.

Yeah... this is really good. After having less than ideal experiences elsewhere, we're now able to distribute patent drawings to our customers from super close. Zero config CDN? Yes, please. Now our users can sift through patent drawings at warp speed no matter where they are.

phoenix_live_reload now ships server logs to the web console for collocated cli/server logs. No more fumbling around to figure out if a UI bug was a cli or server issue. Huge improvement to DX whether building SPAs or LiveView. Writeup on how to enable:

If the user toggles them off and on, we have to send that massive diff every time. What I'd love to do is send it once, but only when it's toggled on the first time. After that, I'd like to use JS show/hide. Is anyone doing something like this? How would it look?

@wojtekmach I've been having a ton of fun with this. One thing I really loved was how easy it was to add Tailwind, but then I struggled to figure out how to add a css file from CDN in the page head, e.g.

Use daisyUI from CDN — Tailwind CSS Components ( version 4 update is here )

How to use daisyUI from a CDN?

Okay so why? Mainly: OTP. Also: good choices. Nx is built with inspiration from JAX from the get-go. There's real second-mover advantage here, using metaprogramming to go with pluggable backends and compilers from day one. My ElixirConf EU talk covers why this is so powerful.

If anybody is using the excellent `nix-beam-flakes` and is sad it's unmaintained, I'm maintaining a fork. I think @mitchhanberg I saw you had a fork too? #myelixirstatus

When you start thinking about things in terms of processes and message passing, everything just clicks. It feels crazy at first, but you come to realise that the way OTP works is the way we should be thinking about architecting AI-powered apps.

You need to be able to fan out/in, handle retries, validate results, handle failure/crashes, wait on potentially long-running results, accumulate batches, broadcast results, push streams to clients, process streams in-flight, etc etc. These are all the things OTP makes simple.
