Hey! We are presenting CodeTracer - a user-friendly time-traveling debugger designed to support a wide range of programming languages: https://github.com/metacraft-labs/codetracer?tab=readme-ov-f... CodeTracer records the execution of a program into a sharable self-contained trace file. You can load the produced trace files in a GUI environment that allows you to move forward and backward through the execution and to examine the history of all memory locations. They say a picture is worth a thousand words — well, a video is even better! Watch the demo below to see…
- RLRestate – Low-latency durable workflows for JavaScript/Java, in Rust2024 · restate.dev · ▲185
We'd love to share our work with you: Restate, a system for workflows-as-code (durable execution). With SDKs in JS/Java/Kotlin and a lightweight runtime built in Rust/Tokio. https://github.com/restatedev/ https://restate.dev/ It is free and open, SDKs are MIT-licensed, runtime permissive BSL (basically just the minimal Amazon defense). We worked on that for a bit over a year. A few points I think are worth mentioning: - Restate's runtime is a single binary, self-contained, no dependencies aside from a durable disk. It contains basically a…

- OSOpen-source in-browser code editor/executor with REPL, 10+ languages2023 · github.com · ▲29
I am super excited to open-source the code executor behind logicboard.com - an in-browser collaborative code editor. The backend is written in Elixir+Phoenix and implements a WebSocket API to execute code in docker containers. Next steps include making this more secure, I am considering Google's gVisor to implement better isolation between containers and the host kernel.
