New week new demo!

A quick look into remote persistent sessions with Superlogical!

RE: https://hachyderm.io/@mitchellh/117202903279918618 Guess which one is Rust btw. 🤣 (The point is the language isn't a free lunch for performance.

RE: https://hachyderm.io/@mitchellh/117202903279918618 A video explaining a handful of the tricks we use to optimize for memory within the Superlogical server: in-memory compression, moving file descriptors between event-driven and blocked threads dynamic…

The Superlogical server is built to run anywhere and everywhere and serve a level of scale (terminals+clients) unmatched w/ prior solutions.

I can't tell you the number of people over my career that have said "I tried learning tmux" First problem: the fact you have to "learn it" at all.

The Ghostty memory usage memes are dead with the upcoming 1.4 release, much to the dismay of internet trolls everywhere. ~10x less memory for a visible window. ~450x lower for a non-visible window.

OSC parsing in libghostty was our last non-SIMD optimized VT stream path.

I still read and write code myself and love it.

RE: https://hachyderm.io/@mitchellh/117135178412268410 Part of the LLM-assisted work here is that Fable+Sol put together a test suite of over 400 cases that are bare shell scripts plus a harness that runs Kitty and Ghostty GUIs and captures their full pty…

Ghostty (and libghostty!)

I've moved on to optimizing libghostty Wasm runtime memory usage and I am learning a lot!

For Wayland people, one of Ghosttys maintainers made a libghostty based Wayland terminal.

RE: https://hachyderm.io/@mitchellh/117096080032017532 Okay, I attacked the libghostty wasm binary size.

RE: https://hachyderm.io/@mitchellh/117096017608717427 A couple more notes on this: First, the xterm.js benchmarks were very noisy.

libghostty for WebAssembly got a lot of love recently and is now very, very, very good.

OSC8 is the terminal sequence for linking arbitrary text (similar to `a` tags in HTML).

The Ghostty non-profit has signed our first long-term paid contributor via a 12-month agreement with @vancluever.

I've started a new company: Superlogical!
