Charm – tools to make the command line glamorous
TUIs over ssh/telnet can be a lot of fun. Especially in cases where multiple people can interact with each other on the server. It simplifies the programming model as you only have one state on the backend that you render to multiple connections. Syncing up everyone becomes trivial. You can also use some React concepts, like rendering a virtual TUI and sending just the right set of minimal escape sequences back to the user to bring their display up to date.
A few months ago I implemented a telnet chat server[0] for fun and it was surprisingly easy to do so. Even by using a wasm vm that I was still working on at the same time.

Launch HN: Lunatic (YC W21) – An Erlang Inspired WebAssembly Platform
We are investing a lot of effort into making Lunatic feel native to the particular language and ecosystem. If you look at the Rust chat server we built in Lunatic (https://github.com/lunatic-solutions/chat), it fully integrates with cargo. You just run your typical “cargo run” command, it will compile the app to wasm and use lunatic to run it. If you want to run your test, you can just do “cargo test”.
wasm-bindgen is necessary only because it’s really hard right now to merge the wasm world and the JS one in the browser. We have the advantage here of staying out of the browser.

How I built a telnet chat server in 2021 with WebAssembly
It took me around a week to build it with Rust + Lunatic and you can check out the code here. If you would like to try it out you can connect to it with:

The Stakker actor runtime: Beyond "Go++"
Recently I implemented a command line chat server in Rust using an actor framework. I model each TCP connection as an actor.

I built a telnet chat server with WebAssembly
Hi HN,
I'm working on an Erlang inspired WebAssembly runtime for the backend[0]. Recently I added TCP support and was looking for apps I could build with it. I ended up building a telnet line chat app. It was a great dogfooding experience and has a nice retro feel to it.
You can access the US server with:
> telnet lunatic.chat
or the EU one with:
> telnet eu.lunatic.chat
Pick the one closer to you, as all the rendering is done on the backend and lower latency will mean better UX.
The server is open source[1] and written in Rust. The Rust code is then compiled to WebAssembly and runs on top of Lunatic. Each connection runs in a separate (lightweight) process, has it's own state and sends just a diff of esc-sequences back to the terminal to bring it up to date with the current render buffer. Everything is deployed to an ARM Linux box.

Ruby 3.2.0 Is from Another Dimension
The java based ruby, removes the GIL, which provides us real multithreading.
Truffleruby is "A high performance implementation of the Ruby programming language, built on GraalVM." If you prefer there is even a rust based ruby https://github.com/artichoke/artichoke
again, IMO, the microbenchmark, doesn't matter. What matters is the problem domain, whole stack and the whole "speed", including development, deployment and etc, and for some domains, ruby is the best and fast choice.

Not to be pedantic but Ruby has webassembly support, still won't work on the BEAM.

When I look at ruby code written in C, I have one thought. Why isn't Ruby rewritten in Crystal, which would make use of parallelism?

Announcing strftime-ruby v1.0.0, a pure Rust no-std implementation of Ruby 3.1.2 Time#strftime method.
I believe it was written mainly for/within the context of artichoke, which is an implementation of Ruby written (mostly) in Rust. It's a neat project!
