Show HN: I'm making an open-source platform for learning Japanese (Score: 150+ in 9 hours)
Link: https://readhacker.news/s/6B8gw
Comments: https://readhacker.news/c/6B8gw
The idea is actually quite simple. As a Japanese learner and a coder, I've always wanted there to be an open-source, 100% free for learning Japanese, similar to Monkeytype in the typing community.
Unfortunately, pretty much all language learning apps are closed-sourced and paid these days, and the ones that are free have unfortunately been abandoned.
But of course, just creating yet another language learning app was not enough - there has to be a unique selling point. And then I thought to myself: why not make it crazy and do what no other language learning app ever did by adding a gazillion different color themes and fonts, to really hit it home and honor the app's original inspiration, Monkeytype?
And so I did. Now, I'm looking to find contributors and testers for the early stages of the app.
Why? Because weebs and otakus deserve to have a 100% free, beautiful, quality language learning app too！

Comments: https://readhacker.news/c/6B2CR
This is the first half of my book, “Swimming in Tech Debt”. It is available at a pre-launch sale price of $0.99 (https://loufranco.com/tech-debt-book).
I have been working on it since January 2024. It is based on some posts in my blog, but expands on my ideas quite a bit.
In September 2024, excerpts appeared in Gergely Orosz’s Pragmatic Engineer newsletter, which helped me get a lot of feedback that expanded the book from my initial idea. This half is about what I expected to do before that —- the rest of the book goes into team and CTO practices.

Comments: https://readhacker.news/c/6B8Nj
Years ago I stumbled across a basic version of this concept and it stuck with me. I knew if I was ever going to take on such a project, it would need to be flawless, but without coding experience it was just another idea that would never happen. By the end of 2024, as AI coding tools exploded everywhere, I finally had a way to make it real.
I started from zero knowledge and spent months collaborating with AI agents as a learning experience. Every pixel and every function went through me. The AI translated what I asked for into code, but every decision was human. I didn't use existing OS frameworks because the goal was learning how basic coding languages worked while also developing my skills with AI collaboration. Apart from basic libraries like xp.css and paint.js, it's all original code.
The result is a fully functional Windows XP recreation running in your browser. Complete experience with sounds, animations, and working applications. Even works properly on mobile, which required rebuilding everything to maintain the authentic feel without becoming unusable on touchscreens.
This project taught me more about coding and AI collaboration than I ever expected. Would love to hear your thoughts on the execution and any feedback on the technical approach.

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