Show HN: Spall – WASM-based profiler for JavaScript and C in ~5k lines of Odin [I'm the author] Spall is a web-accessible profiler that I made to help my web-dev friends load gigabyte+ JSON traces without lunch-break-long load times. Recently, Spall got experimental support for auto-tracing with binary traces (along with an in-progress native-port, to give it more memory headroom), which was used to help track down and fix some hard-to-spot lock contention issues in the Odin-language compiler. I demoed it at the Handmade Seattle conference in October, https://ift.tt/GwOhdng , with a head-to-head against Perfetto, another big web profiler. I'll be around to answer any questions. Thanks for looking at my project! If you like Spall, you can catch my other projects over at https://ift.tt/VYhQjXc . If you happen to be hiring I'd love to hear from you. Looking for something fun and new to do after a long sabbatical, working on cool open-source projects! https://ift.tt/y2G98tV January 2, 2023 at 07:37PM
