    I built FlouState because "4 hours of coding" tells you nothing. Was it 4 hours debugging or 4 hours building features? Very different. It's a VS Code extension that automatically categorizes your coding into: Creating (new features), Debugging (fixing issues), Refactoring (improving code), or Exploring (learning codebase). Example: Yesterday I "coded" 6 hours but it was actually 3.5h debugging a race condition, 1.5h refactoring, 0.5h tests, 0.5h exploring. Traditional time trackers just show "6 hours in TypeScript." Technical: Tracks file changes, debug sessions, and edit patterns locally.…

    Hey HN, the is Chris, creator of FireDBG. We’ve been working on this debugger just about a year now. Time travel debugging isn’t a new concept, the new idea here is to use call tree visualisation to help us navigate the debug trace. It supports various Linux distros on x64 and macOS on x64 and M1. It’s only available for Rust right now, but we do want to bring this debugging experience to other programming languages. Please give it a try! Would love to know your thoughts. What’s your anecdote in debugging programs? My stupidity is usually in the form of: after a few hours of debugging, I…

    Hello HN! I've recently released and open-sourced a time travel debugging VSCode extension for Python, Javascript & Typescript. https://github.com/dedale-dev/ariana It's born from the pain of spending hours reproducing bugs, struggling to read parallel streams of logging across client/server, and managing print/console.log statements. You can see a short video here: https://www.youtube.com/watch?v=M2gZv7IOo7s Basically its two parts: One part CLI called `ariana` that you install with npm/pip and run alongside your code's run command. For…

    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…
