Show HN: Open-lmake, a scalable, reliable build system with auto dep-tracking Hello Hacker News, I often hear people saying "all build-systems suck", an opinion I have been sharing for years, and this is the motivation for this project. I finally got the opportunity to make it open-source, and here it is. In a few words, it is like make, except it can be comfortably used even in big projects using HPC (with millions of jobs, thousands of them running in parallel). The major differences are that: - dependencies are automatically tracked (no need to call gcc -M and the like, no need to be tailored to any specific tool, it just works) by spying disk activity - it is reliable : any modification is tracked, whether it is in sources, included files, rule recipe, ... - it implements early cut-off, i.e. it tracks checksums, not dates - it is fully traceable (you can navigate in the dependency DAG, get explanations for decisions, etc.) And it is very light weight. Configuration (Makefile) is written in Python and rules are regexpr based (a generalization of make's pattern rules). And many more features to make it usable even in awkward cases as is common when using, e.g., EDA tools. Give it a try and enjoy :-) https://ift.tt/N0FE52G May 3, 2025 at 09:41PM

Show HN: Traycer.ai – Turn GitHub Issues into a Step-by-Step Plan https://ift.tt/Jh1bkpM

Show HN: Traycer.ai – Turn GitHub Issues into a Step-by-Step Plan Hey everyone! We've built Traycer, a tool that transforms your GitHub issues—everything from descriptions and attached images to ongoing conversations—into clear, actionable implementation plans. You can easily import these plans into your IDE with our extension or use them with any other coding assistant you prefer. We'd love to hear your thoughts and feedback. Traycer is totally free for open-source projects, and we've got a 2-week free trial if you're working with private repos. Give it a try and let us know what you think! https://ift.tt/n2A8ZcH May 3, 2025 at 01:56AM

Show HN: I built a synthesizer based on 3D physics and launched the product https://ift.tt/1JHwOzM

Show HN: I built a synthesizer based on 3D physics and launched the product I've been working on the Anukari 3D Physics Synthesizer for a little over two years now. It's one of the earliest virtual instruments to rely on the GPU for audio processing, which has been incredibly challenging and fun. In the end, predictably, the GUI for manipulating the 3D system actually ended up being a lot more work than the physics simulation. So far I am only selling it direct on my website, which seems to be working well. I hope to turn it into a sustainable business, and ideally I'd have enough revenue to hire folks to help with it. So far it's been 99% a solo project, with (awesome) contractors brought in for some of the stuff that I'm bad at, like the 3D models and making instrument presets/videos. The official launch announcement video is here: https://www.youtube.com/watch?v=NYX_eeNVIEU But if you REALLY want to see what it can do, check out what Mick Cormick did with in on the first day: https://ift.tt/jYDIAH8 I've kept a fairly detailed developer log about my progress on the project since October 2023, which might be of interest to the hardcore technical folks here: https://ift.tt/AnyrfbC I also gave a talk at Audio Developer Conference 2023 (ADC23) that goes deep into a couple of the problems I solved for Anukari: https://www.youtube.com/watch?v=lb8b1SYy73Q https://anukari.com May 2, 2025 at 11:42PM

Show HN: Lichen – Manage and create code licenses on the CLI and with TOML https://ift.tt/WvYtBXT

Show HN: Lichen – Manage and create code licenses on the CLI and with TOML Hey! I'm Miles, I built this tool to be a fast and reliable solution for generating licenses on the CLI. Licensing has always been a point of stress for me, with how much is at stake. If I copy one from the wrong website, the version I download is the wrong one, or any number of mishaps, my whole code is at risk. We see this fiasco play out all the time. We shake our saddened heads and go on. No longer! Lichen is designed to generate licenses sensibly with three words on the CLI. `lic gen MIT`. Or in a `.lichen.toml` in your project root. Add authors/maintainers with --authors, date it with --date, license specific parts with exclude patterns and double licenses. Project big or small, it's got everything (I think). (Tell me what it's missing please). It uses SPDX licenses for correctness. Written in Rust, you'll know you're safe, and if you want to be extra cautious, feel free to create license headers on all your files (Fast too! Can do this for the entire cargo project in 22s uncached). I'm happy to answer any questions/concerns/whatever about my tool, it's my biggest project to date (And therefore my most bug-ridden...) https://ift.tt/vZg5yCI May 1, 2025 at 10:25PM
