Show HN: Sharpe Ratio Calculation Tool

I built a simple but effective Sharpe Ratio calculator that gives the full historical variation of it. Should I add other rations like Calmar and Sortino?

New top story on Hacker News: Show HN: EnrichMCP – A Python ORM for Agents
Show HN: EnrichMCP – A Python ORM for Agents
30 by bloppe | 4 comments on Hacker News.
I've been working with the Featureform team on their new open-source project, [EnrichMCP][1], a Python ORM framework that helps AI agents understand and interact with your data in a structured, semantic way. EnrichMCP is built on top of [MCP][2] and acts like an ORM, but for agents instead of humans. You define your data model using SQLAlchemy, APIs, or custom logic, and EnrichMCP turns it into a type-safe, introspectable interface that agents can discover, traverse, and invoke. It auto-generates tools from your models, validates all I/O with Pydantic, handles relationships, and supports schema discovery. Agents can go from user → orders → product naturally, just like a developer navigating an ORM. We use this internally to let agents query production systems, call APIs, apply business logic, and even integrate ML models. It works out of the box with SQLAlchemy and is easy to extend to any data source. If you're building agentic systems or anything AI-native, I'd love your feedback. Code and docs are here: https://ift.tt/VbjSdyB . Happy to answer any questions. [1]: https://ift.tt/VbjSdyB [2]: https://ift.tt/Sd76aQp

Show HN: Trieve CLI – Terminal-Based LLM Agent Loop with Search Tool for PDFs
15 by skeptrune | 0 comments on Hacker News.
Hi HN, I built a CLI for uploading documents and querying them with an LLM agent that uses search tools rather than stuffing everything into the context window. I recorded a demo using the CrossFit 2025 rulebook that shows how this approach compares to traditional RAG and direct context injection[1]. The core insight is that LLMs running in loops with tool access are unreasonably effective at this kind of knowledge retrieval task[2]. Instead of hoping the right chunks make it into your context, the agent can iteratively search, refine queries, and reason about what it finds. The CLI handles the full workflow: ```bash trieve upload ./document.pdf trieve ask "What are the key findings?" ``` You can customize the RAG behavior, check upload status, and the responses stream back with expandable source references. I really enjoy having this workflow available in the terminal and I'm curious if others find this paradigm as compelling as I do. Considering adding more commands and customization options if there's interest. The tool is free for up to 1k document chunks. Source code is on GitHub[3] and available via npm[4]. Would love any feedback on the approach or CLI design! [1]: https://www.youtube.com/watch?v=SAV-esDsRUk [2]: https://ift.tt/GAJDP1z [3]: https://ift.tt/MPs0cay... [4]: https://ift.tt/FXkA8rq

Show HN: ChatToSTL – AI text-to-CAD for 3D printing
4 by flowful | 0 comments on Hacker News.
Hey HN, I'm a beginner at CAD so I built an app that does it for me ;) Describe a part and ChatToSTL writes the OpenSCAD code, shows a live render with size sliders, then exports the STL/3MF file. Because the output is parametric, it's easy to modify (unlike mesh models like Shap-E or DreamFusion). Try it (needs your own OpenAI key): https://ift.tt/5XQjy4x How it works: Text prompt → o4-mini generates OpenSCAD code → live render + sliders → refine in chat → export. Examples & Code: * Walkthrough + real prints (bowl, hook, box, door stop): https://ift.tt/xPKvplG... * 90-sec demo: https://www.youtube.com/watch?v=ZK_IDaNn1Mk * MIT repo: https://ift.tt/1qLp5b6 Current limitations (it's not replacing Fusion 360 anytime soon): - Simple shapes only. Even a mug can end up with a misplaced handle - Works best with CAD-style language ("extrude 5mm") - AI can't see the render, so no self-correction yet I'm particularly interested in feedback on improving the 3D generation quality: should I add vision feedback so that it can self critique? use CADQuery instead of OpenSCAD? use a different model? Thanks! Nico

Ask HN: What cool skill or project interests you, but feels out of reach?
9 by akktor | 14 comments on Hacker News.
This question's for all those cool projects or skills you're secretly fascinated by, but haven't quite jumped into. Maybe you feel like you just don't have the right "brain" for it, or you're not smart enough to figure it out, or even worse, you simply have no clue how or where to even start. The idea here is to shine a light on these hidden interests and the little (or big!) mental blocks that come with them. If you're already rocking in those specific areas – or you've been there and figured out how to get past similar hurdles – please chime in! Share some helpful resources, dish out general advice, or just give a nudge of encouragement on how to take that intimidating first step. Let's help each other get unstuck!

New top story on Hacker News: Show HN: I build one absurd web project every month
Show HN: I build one absurd web project every month
25 by absurdwebsite | 9 comments on Hacker News.
I’ve been building absurd, mostly useless web projects for fun — and I publish one every month at absurd.website. These are deliberately non-functional, weird, sometimes funny, sometimes philosophical — and usually totally unnecessary. Some examples: Sexy Math — solve math problems to reveal erotic images. Trip to Mars — a real-time simulation that takes 7 months to finish. Add Luck to Your e-Store — add a waving cat widget to boost your conversion via superstition. Microtasks for Meatbags — the future: AI gives prompts, humans execute. Invisible Lingerie — it’s sexy. And invisible. Artist Death Tracker — art prices spike when artists die. We track that. Open Celebrity — one open-source face, shared by all. Together we make her famous. I just enjoy exploring what the web can be when it doesn’t try to be “useful”. Would love to hear what you think — and absurd ideas are always welcome.
