[Other] Show HN: Evalyze – AI investor matching from your pitch deck (feedback welcome) I used to work in VC and watched good teams lose months chasing the wrong investors. I’m building Evalyze to make the unglamorous parts faster and more precise.<p>After sign-up (email only, no card) you can:<p>- upload a deck or paste your site - get a ranked list of relevant VCs&#x2F;angels with a short “why” for each<p>What’s different: instead of dumping a big list, we try to explain why an investor fits based on stage, sector, check size, and portfolio patterns. It’s far from perfect and we want blunt feedback before opening wider.<p>Limits to know:<p>- newer funds and emerging managers can be underrepresented - geo nuances are still rough - matching can over-weight buzzwords if the deck is vague<p>I’d love critique on the ranking logic, signals you’d add&#x2F;remove, and any privacy concerns. If you don’t want to upload a deck, there’s a sample you can use to see the flow.<p>I’ll be here replying and shipping fixes as comments come in.

[Other] Show HN: Inception: Automatic Rust Trait Implementation by Induction Hi HN,<p>I thought this would be a good place to share a little puzzle I&#x27;ve been working on. Inception is a Rust library that helps you share behaviors in Rust using structural induction. Practically, this means that instead of having a derive macro for each behavior, a single derive can be used to enable any number of behaviors. It doesn&#x27;t do this using runtime reflection, but rather type-level programming - so there is monomorphization across the substructures, and (at least in theory) no greater overhead than with macro expansion.<p>While there are a lot of things missing still and the current implementation is very suboptimal, I&#x27;d say it proves the general concept for common structures. Examples of Clone&#x2F;Eq&#x2F;Hash&#x2F;etc replicas implemented in this way are provided.<p>The code is not idiomatic, which is my biggest reservation about continuing this work. It was fun to prove, but is not so fun to _improve_, as it feels a bit like swimming upstream. In any case I hope some of you find it interesting!

[Other] Show HN: Open-sourcing our text-to-CAD app Hey HN! I&#x27;m Zach from Adam (<a href="https:&#x2F;&#x2F;adam.new&#x2F;">https:&#x2F;&#x2F;adam.new&#x2F;</a>). We’re building an AI co-pilot for mechanical CAD software.<p>As part of our broader research, we built a browser-based Text-to-CAD app (<a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=44182206">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=44182206</a>) and are now open sourcing it. This is a React SPA with a Supabase backend.<p>What it does:<p>* Generates parametric 3D models from natural language descriptions, with support for both text prompts and image references<p>* Outputs OpenSCAD code with automatically extracted parameters that surface as interactive sliders for instant dimension tweaking<p>* Exports as .STL or .SCAD<p>Under the hood:<p>* Separate agents for conversation and code generation; simple parameter tweaks bypass AI entirely using deterministic regex-based updates<p>* Runs fully in-browser by compiling OpenSCAD to WebAssembly and integrating Three.js with React Three Fiber for 3D rendering<p>* Supports BOSL, BOSL2, MCAD libraries and custom font support (Geist) for text in models<p>We’ve seen many developers trying to replicate this kind of functionality, so we’re releasing this to give the community a solid foundation to build on.<p>Future improvements:<p>* Expand geometry support - Move beyond CSG primitives to support curved surfaces, fillets, lofts, and constraint-driven modeling through CadQuery&#x2F;Build123D<p>* Better spatial context - UI for face&#x2F;edge selection and viewport image integration to give LLMs spatial understanding<p>* Enhanced capabilities - RAG on documentation and integration with more OpenSCAD libraries for features like proper threading<p>You can clone the repo and run it locally! Contributions are welcome, and we’ll keep merging PRs as they come in.
