Show HN: I made a web app to bring children's drawings to life
Hey HN!<p>I used to spend hours drawing all kind of things as a kid. Sadly though, those drawings are long gone.<p>Inspired by this, I created DoodleDreams. A webapp that brings drawings to life using AI and stores them as memories. You can always look back at the drawings, see who made them, and even know the age they were drawn at.<p>I thought it was a fun way to preserve those memories. What do you think?<p>Viktor

Show HN: I've made a Monte-Carlo raytracer for glTF scenes in WebGPU
This is a GPU "software" raytracer (i.e. using manual ray-scene intersections and not RTX) written using the WebGPU API that renders glTF scenes. It supports many materials, textures, material & normal mapping, and heavily relies on multiple importance sampling to speed up convergence.

Show HN: Super Snowflake Maker
Hi all! Just released Super Snowflake Maker!<p>Draw on the pie with freeform or polygon tools, change the number of sections, click on the large snowflake to see fold, and.... download!<p>Enjoy + Happy Holidays!<p>(tech: threejs/r3f, react, ts, useSpring, tailwind, canvas, svg, offscreen canvas, paperjs)

Show HN: Map of YC Startups
Hey Everybody! Hope you had a merry christmas<p>Today I had a bit of fun with Claude.<p>Started by scraping YC's startups list, then ran them through OpenAI's embedding service, then UMAP'd the embedding to reduce the dimension to just two coordinates and then just forced Claude to write React that would compile to visualize that.<p>I had fun and I think it's interesting, so take a look!<p>Also note that you won't be able to zoom on mobile (found about this Plotly limitation way too late). If there's interest I can fix this issue by changing plotting libs tomorrow :)<p>Merry christmas

Show HN: I made a website to semantically search ArXiv papers
As a grad student (and an ADHDer), I had trouble doing literature review systematically. To combat this, I made a website that finds similar papers using the meaning of the thing I am looking for.<p>I used MixedBread's [^1] embedding model to generate vectors from the abstracts. I store and search similar vectors using Milvus [^2] and finally use Gradio [^3] to serve the frontend. I update the vector database weekly by pulling the metadata dataset from Kaggle [^4].<p>To speed up the search process on my free oracle instance, I binarise the embeddings and use Hamming distance as a metric.<p>I would love your feedback on the site :)

Show HN: FixBrowser – a lightweight web browser created from scratch
Hello, I'm working on a web browser that focuses on being truly lightweight and designed for privacy.<p>At some point I've realized that much of the complexity and resource requirements of web browsers comes from JavaScript. This is because every part needs to be dynamic and optimized for speed.<p>So a few years ago I've started to work on a web browser that intentionally doesn't implement JavaScript, instead it contains an updated set of scripts that fix and improve various websites.<p>I've been using this approach using a proxy server for a few years as my primary way of web browsing with good results. It uses a whitelist approach where no resources are loaded from different domains by default (the fix scripts can override it to load images from CDNs, etc.). This avoids any trackers by default.<p>You can find more details on the homepage of the project:<p><a href="https://www.fixbrowser.org/" rel="nofollow">https://www.fixbrowser.org/</a><p>I'm currently running a fundraiser to get it really going. All the foundation blocks are there it just needs some more work. Any support is welcome.

Show HN: AuthorTrail – Browse files you've touched in a Git repo
This was more so an exercise in prompting with Lovable and Cursor than it was in creating a highly polished product/tool. Yet the end result works :)<p>AuthorTrail is a locally running web UI that you can point to any Git repo. It will then look for all the files you have ever touched. This can be useful for large repos with lots of activity, where you want to remind yourself how you did something in the past. For example, I am using it to remind myself how I wrote an obscure unit test, without needing to browse my older PRs.<p>Feedback welcome!
