There is now a channel on slack for this project. https://elixir-lang.slack.com/messages/C56H3TBH8/details/
Canāt believe it took me this long to find this paper āYour Server as a functionā
Operations are phrased as value transformations,encouraging the use of immutable data structures and, we believe,enhancing correctness through simplicity of reasoning.
While most of our engineers find the programming model un-usual, they tend to internalize it quickly.
The whole paper is discussed in a Scala/Java context so some parts donāt translate well, e.g. there is no need to talk about Futures. However it is interesting to see some of these ideas explained more rigorously than I ever managed when talking about Raxx.
There is also a discussion about interrupting ongoing processing, for example in the case of a timeout.
This is an equivalent here, in Elixir/Erlang. e.g. a Gen call can timeout, but the processing will continue and the reply potentially be returned to the mailbox later.
Is anyone sending interrupt message to processes in the case of a call timeout.
Finally the paper is in a typed language. The idea of statically verifying that only authenticated requests are passed to a service(http handler) that requires authentication is very appealing.
Although less easy to see how this can be useful in Raxx, it might be useful to Midas,

Aw man, just as I āgot into itā he started talking fast as hell. Streaming actually sounded nice, is there any āfullā version of his speech?
You can slow down the playback speed on YouTube Mr GD 
I think Peter has done a few talks about Raxx and this one seems to be one of the latest:
IIRC I think he shifted focus on to a Raxx-like framework for Gleam, called Midas: GitHub - midas-framework/midas: A web framework for Gleam, Midas makes shiny things.
Perhaps @Crowdhailer can give us a little update on what heās up to these days

Sorry about that, You found the very first, I hope Iāve got better with time.
Iāve done quite a few talks on Raxx, though not very recently. I think itās now so stable to not be interesting. It gets a lot of downloads on hex. Though not that many PRās to fix the depreciation warnings.
@AstonJ is right that right now my focus is on Gleam. Basically with Raxx I felt like I was fighting against the Elixir ecosystem to get to simplicity and solid functional programming principles.
In Gleam basically every interface is as nice as the Raxx one, and you get a compiler to tell you when youāve made a mistake. I love Gleam but itās pretty early days for it.
Anyways donāt take anything away from Raxx itās still solid and useful, just not making much noise about it.

I tried to understand the pricipal difference between Raxx and Plug and I believe it is that
- Raxx uses a middleware stack that wrap each other: they call the next middleware and can work with the return value of the āinnerā call
- Plug uses a āforwardā model where each middleware is called in order, their return value is passed to the next middleware.
Is that is ?

I think Raxx fell into the same trap that Sinatra did - it focused on simplicity but people wanted all the bells and whistles of frameworks like Rails and Phoenix 
however the Elixir community has grown a lot since then, and I wonder whether you might find that enough people now may be interested in such a framework?
Iām curious what you mean by the latter part of your sentence - in what way did the Elixir ecosystem get in the way of functional programming principles?
