Readit Newslawik commented on I let LLMs write an Elixir NIF in C; it mostly worked overbring.com/blog/2025-0... · Posted by u/overbring_labs
I've done this. The NIF worked as in that it ran and was a correct enough NIF. It did not work in terms of solving what I needed it to do. Iteration was a bit painful because it was tangled with a nasty library that needed to be cross-compiled. So when I made a change it seg faulted and I bailed.
I essentially ran out of patience and tried another approach. It involved an LLM running C code so I could check the library output compared to my implementation to make sure it was byte-for-byte.
The C will never ship. I don't have practice writing C so I am very inefficient at it. I read it okay. LLMs are pretty decent help for this type of scrap code.

I wonder if they'll be satisfied there or add a chunk of others now that they've started. Parakeet is supposed to be good?
Should they add Voice Activity Detection? Are these separate filters or just making the whisper filter more fancy?

That is good.
Then actual propper benchmarks will be remarkable.
However BEAM is not the only factor in this process. the entire hardware platform as well.
This is after all a lot about that nice and huge cpu.
I mean when you have all 5000 started why not let the do some work? Stress test it with a few real life scenarios for 48h and let us see some number.
I will consider it :)

The article is about 5000 Erlang nodes (BEAM VMs), not processes - a single BEAM instance can efficiently handle millions of lightweight processes, making this even more impressive from a density perspective.
I really should see how many 1 million process BEAM VMs can fit...

So this is something like a 5000 USD machine
(https://www.jeffgeerling.com/blog/2024/ampereone-cores-are-n...)
And is designed as a cloud provider or telco edge machine (hence the erlang consultancy)
But if you are looking at a hosted erlang VM for a capex of one dollar then these folks are onto something
Cores really are the only way to escape the broken moores law - and this does look like a real step in the important direction. Less LLMs more tiny cores
I found out that Ampere is into edge and telco usage way after we got connected to do this work actually. I've been an Elixir dev and through that connected to Erlang for 7-ish years.
But I will certainly try to leverage my telco-connection to get to play with more of their kit if I can.

"5000 Erlangs" - oh, they meant 5000 instances of some Erlang interpreter.
Not Erlang as a unit of measure.[1] One voice call for one hour is one Erlang.
I was aware an Erlang being a unit though I'd forgotten what it measured. I Need to have my fun when giving titles to these things. Hope it fell within bearable tolerances.

Neat! I always thought the name of the Erlang programming language just meant “Ericsson Language”, since this programming language was invented for Ericsson. Never knew there was anything more than that to the name!
According to Robert Virding at an unnamed bar in Berlin ~3 years ago they just wanted to be like Pascal in terms of picking a mathematician. But Ericsson Language certainly helped sell it internally, I'm sure.
Can someone explain this ideological whiplash?
Intel's death would be very embarassing to that whole effort. So Intel has incentives (survival) and the administration has incentives (jobs in the US). The method is "whatever can be claimed as a win".
No US party seems particularly capable or keen to hold an ideological line but especially not the GOP from what I've seen. Not saying other countries have particularly impressive parties either. I'm less than thrilled with ours over here.
