Changed attention so its linear first layer , middle quadratic layer, last linear layer Inference got much faster with a low perplexity hit in tests .Full attention O(n²): 17.96s / 5.6 tok/sHybridAttention O(n·W + n·D): 0.35s / 286.6 tok/sI have been building a small Rust focused language model from scratch in PyTorch. This is not a finetune. It is byte level, trained from random initialization on a Rust heavy corpus assembled here: https://codeberg.org/JohannaJuntos/SisyphusModel and training setupThe model has 25.6M parameters with a 512 context length. It uses a byte level vocabulary of 256, with 8 layers, 8 heads, and 512 dimensional embeddings. Positional embeddings are learned and the embedding and LM head weights are tied.Training ran for 30k steps on a 173.5M byte Rust corpus using a single RTX 4060 Ti 8GB.Final metrics were a train loss of 0.5834, validation loss of 0.8217, and perplexity of 2.15.

Show HN: Petrarca: Voice first spaced repetition – track knowledge across bookshttps://networkedthought.substack.com/p/petrarca-an-intelligent-companionI've been struggling for years to get an overview (become literate) in history as an adult. I wanted all the names (Cicero, Caesar, Constantinople, Waterloo) to actually mean something, because reading books and deeper analyses becomes so much more interesting then.But I also didn't want an app that forced me to do all my reading on screen - I want to read physical books on the couch, listen to a history podcast when I walk, watch a documentary with my wife. And still track what I learnt, and maintain it...So I built an app that let's me track which books I am reading by taking a picture of the cover (it automatically researches them, inserts TOC and content, autosyncs with Kindle progress etc), and generates review questions based on book content and generated "curricula".But to map the things I already know, I designed a "knowledge elicitation" using voice - it gives me some prompts (what do you know about Plato), I talk into the mic while walking, and it maps what I know, my mistake

Show HN: Onboardly – Ask questions about any GitHub codebase in plain Englishhttps://onboardly-ruddy.vercel.appA few months ago, I asked HN about the biggest pain points when joining a new team (https://news.ycombinator.com/item?id=47368472). Most people said it was the tribal knowledge buried in the code.I've spent my time as a student building Onboardly to solve this. It’s a web app that indexes your GitHub repo and lets you ask questions in plain English. Unlike a general LLM, it cites the exact files it’s looking at so you can verify the logic.Tech stack: FastAPI backend, Next.js frontend, and a RAG architecture for the indexing. I’m currently hosting it on Render's free tier, so there might be a slight delay on the first login—I'm working on that!I’d love for you guys to break it and tell me where the answers feel 'off' or what features a dev actually needs for onboarding.It's free to try — would love feedback on answer quality across different repo types and languages.https://onboardly-ruddy.vercel.app

From Idea to App Store Was Predictable. From Launch to Traction Was Nothttps://news.ycombinator.com/item?id=47672566When you just have an idea and the plan is only starting to form, everything feels unclear. Building a product to launch seems daunting, overly complicated. And it may indeed be complicated, depending on the product. But in reality - given all the available tools and resources - it is the most ‘plannable’ part. If you are meticulous in planning and diligent in execution, it is also the most predictable part in terms of key results. You start with a concept, move to architecture and systems, and before you know it - you have a prototype to play with. You build, test, improve, iterate, iterate, iterate, and launch. And here’s where the real difficulty begins: everything after “Done”. Let me clarify something upfront: I’m talking about owning an indie product - with no backing whatsoever. The cruel reality hits fast. Zero traffic. Let that sink in: zero traffic. With thousands of apps being launched daily - many backed by real marketing budgets - the real (if not the only) challenge becom

Claude Code limits are starting to feel like a psychological trickhttps://news.ycombinator.com/item?id=47668813I signed up for the Claude Code Pro Subscription about a month ago. and I have been really careful about my limits because I burned through them pretty easily about two weeks ago, but this week Im already at 10% and have been barley using it..Since there is no transparency around the metric for these limits they could easily change the metric and it wouldn't be easy to measure it. I'm thinking about canceling my sub because there is no clear way for me to understand this metric but wanted to see what others thought about this.

Show HN: CacheZero – Karpathy's LLM wiki idea as one NPM installhttps://news.ycombinator.com/item?id=47667723Karpathy's recent tweet about LLM knowledge bases went viral (17M views). He described a system where you dump raw content into a folder, an LLM compiles it into an interconnected wiki, and you search/query it through Obsidian.I built the whole pipeline as a single CLI tool:- Chrome extension to bookmark tweets, articles, YouTube, anything - Hono server + LanceDB for vector search - Claude Code compiles your bookmarks into wiki pages with wikilinks and citations - Browse in Obsidian with graph view - Publish as a static site with Quartznpm i -g cachezerohttps://github.com/swarajbachu/cachezeroWould love feedback on the compile step specifically — the wiki quality depends heavily on the SCHEMA.md prompt and I'm still iterating on it.

Show HN: I built a site that turns your Steam gaming hours into a RL skill treehttps://alternatelife.xyz/Hey,A bit of context..So I think last week was my last straw, I hit 8k hours with dota and holy ** It finally hit me how much time I wasted on that game.I'm a software developer, I always wanted to develop something and put it out but was scared shitless to do so, I was kinda afraid to get bad traction, to fail or even worse to be completely ignored.so I decided to address two of these issues at once, stop playing dota and spend the weekend building a website that let you see what you could've done with your gaming hours.As an avid gamer for the last 20+ years, I know that it's only theoretical, cause sometimes, after a long day u just wanna chill infront of a game and you wouldn't go get a pilot license, obviously.but, a lot of other times, I would spend my days off, weekend, just gaming 10 hours straight like a mad man.In any case, hope u like it and maybe it sparks something in u!

The two most significant updates focus on handling design complexity and automating using agentic workflows. Previous Show HN here:https://news.ycombinator.com/item?id=449781401. Projects:This workflow is more amenable to system-level modeling. It overlaps somewhat with the original workflow but includes improvements including:Complex Routing: Model topologies with branchpoints.Mating Relationships: Represent physical mating (e.g., a receptacle into a PCB header or a ferrule into a terminal block) for completeness.Decoupled BOMs: Part assignment is now separate from component addition; you can generate a BOM and then assign specific MPNs to components as the design evolves.Net Visualization: Nets are identified and visualized across conductors, terminations, and mating relationships.QOL and Visualization Improvements: Assign components to one or more pages to separate designs by function.
