I'm looking for a remote Rust/Elixir role (EU-friendly timezones, US East is ok).

I have 7 years of #rustlang, 9 years of #elixirlang, 20+ years of #linux.

I have over 20 years of experience as a professional developer, and I've been working remotely for 12 years.

[Marcin @sickill]

I helped many US and EU companies build reliable software.

On the side, I've been developing #asciinema, the best tool to record and stream your terminal sessions. I talk about it in the context of Rust in this #RustaceanStation interview: https://t.co/6NsfCP0rYf

The search index includes recording titles, descriptions, and FULL TERMINAL SESSION CONTENT!

It's powered by Postgres' native FTS engine.

asciinema CLI 3.0 is out!

This is a complete rewrite of asciinema in #rustlang, upgrading the recording file format, introducing terminal live streaming, and bringing numerous improvements across the board.

Looking forward to @OxidizeConf next month in Berlin!

Who’s going to be there? Any cool companies?

@mitsuhiko @sthupukari @asciinema For 3.0/3.1 I plan to add RPC mechanism to the CLI so you will be able to send input (keys). Not sure if asciinema player should have it wired though, maybe a spin-off "asciinema terminal" could be built for interactive use :)

[asciinema @asciinema]

This is, hopefully, the last RC before the final release.

Give it a spin, send feedback!

[asciinema @asciinema]

Third RC of the new #asciinema CLI is out!

The highlights:

- support for recording to a directory, with auto-generated filename
- reduced streaming latency in relay mode
- improved RGB color support when streaming on certain terminals (e.g. Kitty)

@solnic_dev @hugobarauna Both Elixir (for server side stuff) and Rust (for CLI) now seem like an end game langs for me (ask me in 5 years though haha).

[Marcin @sickill]

@solnic_dev @hugobarauna Oh, and the CLI was initially in Python, then in Go, then again in Python, and finally in Rust :)

[Marcin @sickill]

@solnic_dev @hugobarauna Haha, yeah. It's in Elixir since ~2016, 8 years already :) Before that Clojure, and before that Ruby (on Rails).

Introducing Headless Terminal (ht) - making terminals easy for LLMs to use.

While using LLM agents for coding I needed something like a headless browser but for terminals. So I teamed up with @sickill (creator of asciinema) to build https://t.co/0JsfHFNHpD - an open source executable that provides text screenshots of a terminal.

Terminals are one of the oldest and most prolific UI frameworks in all of computing. And they are stateful so, for example, when you use an editor in your terminal, the terminal has to manage state about the cursor location. Without ht, an agent struggles to manage this state directly; with ht, an agent can just observe the terminal like a human does.

ht is Apache licensed, written in rust, and works on MacOS and Linux.

Shout-out to @datadoghq, who just became a sponsor of my work on @asciinema. Thanks a lot 🥰!

The result of my Saturday hacking is a complete #nix flake ❄️ for #asciinema 🎉

https://t.co/pQS6vr6Lwe

If you're on #nixos (or running nix elsewhere, including #macos) then you can run the latest version with:

nix run github:asciinema/asciinema
