I made a zero-copy coroutine tracer to find my scheduler's lost wakeups
A cross-language, zero-copy coroutine observability framework based on the cTP shared-memory protocol, utilizing lock-free ring buffers for ultra-low overhead state tracing. - lixiasky-back/coroTracer
I made a zero-copy coroutine tracer to find my scheduler's lost wakeups launched on March 3, 2026 with 49 votes, #718 of 23,380 launches that month and more than 95% of that year's launches.
In plain words
This is a debugging tool designed to trace coroutine execution and identify missing wakeups in scheduler implementations. It uses zero-copy techniques to minimize performance overhead during tracing. The tool is intended for developers working with concurrent systems who need to diagnose scheduler issues. It is available as open source on GitHub.

CodeTracer – A time-traveling debugger implemented in Nim and Rust2025 · github.com · ▲334Hey! 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…

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
