Show HN: I built a S3 proxy that combines storage from S3/clouds into one targethttps://github.com/afreidah/s3-orchestratorI wanted offsite copies of my nomad cluster backups without paying. So I started thinking about how to maximize free S3 storage from multiple providers. What if I could just stack them all together and treat them as one big bucket? I started hacking out a simple proxy and then I was having fun, so I kept building. My weekend project turned into what is basically a fully production-ready S3 orchestration service. You configure multiple S3-compatible backends (AWS, OCI, Backblaze, R2, MinIO, whatever), set a quota on each one, and the orchestrator presents them to your apps as a single S3 endpoint. Clients just sees one bucket with no idea files are being spread across multiple s3 providersWhat makes it useful:- Combine free tiers — set per-backend quotas to match each provider's free limit and the proxy fills them in order (pack mode) or evenly (spread mode). 10GB + 10GB + 10GB = 30GB of free offsite storage- Multi-cloud replication — set replication.factor: 2 and every object automaticMar 4, 2026 1:36 AM

Show HN: TypeShim – .NET WebAssembly Meets TypeScripthttps://github.com/ArcadeMode/TypeShimI'm a big proponent of WebAssembly and .NET. When I found out .NET now runs in the browser on WASM with ánd without Blazor, I figured that could be something. Since Blazor is often too big of a step for TypeScript developers, I figured the recently added ability to include a .NET WASM app as a library in a JS bundle could be a good stepping stone for WASM to gain some ground in this JS-heavy web we have.Using the JSExport/JSImport interop is relatively cumbersome, it only supports static methods, has no OOP concepts (like classes, just object handles) and it requires manually writing TypeScript definitions for the exported methods. So I decided to try and make some tooling that would improve the developer experience and reliability higher.Enter TypeShim: a codegen tool that creates a seamless programming experience between .NET WebAssembly and TypeScript. Complete class level exports are translated to C# codegen to automatically define your JSExports/JSImports with a TypeScript class tMar 3, 2026 9:55 PM

Show HN: HackerNews.pink – A PWA HN reader with personalized recommendationshttps://hackernews.pink/I think everyone should build their own HN reader at least once in their life. This is mine and its pink. I wanted a good HN experience on mobile something I could pull up on the train and browse comfortably. So I built a PWA that works well on mobile and feels native on the phone. Along the way, I kept adding things: Semantic search – Stories are embedded with OpenAI's text-embedding-3-large and indexed in MongoDB 8.2's Vector Search. Search combines vector similarity and full-text via Reciprocal Rank Fusion, so you can find stories by meaning, not just keywords. Personalized feed: A profile vector is built from your reading history and bookmarks (weighted by time spent and recency). After a few stories, the feed adapts to your interests. Content extraction: A Playwright-based scraper fetches article text, generates thumbnails, and extracts metadata. Real-time updates and infinity scroll. Auth is passkey-first (WebAuthn) and works without personal information. Stack: Angular 21, FastAMar 3, 2026 6:28 PM

Show HN: FixYou – AI tool that tells you which cancer screenings you needhttps://www.fixyou.app/The USPSTF and ACS publish thorough cancer screening guidelines, but they're dense and scattered across dozens of pages. What you actually need depends on your age, sex, family history, smoking status, and other factors. Most people, including me until recently, simply don't know what they should be getting checked for.I built FixYou after losing my grandfather to colon cancer that was caught too late. After his diagnosis, my parents went for colonoscopies and found polyps, early and treatable. We didn't lack access to healthcare. We lacked clarity.FixYou is a free tool that: 1. Walks you through a short AI conversation about your health profile 2. Cross-references your answers against current USPSTF and ACS screening guidelines 3. Gives you a "Shield Score" (0 to 100) and a prioritized list of screenings to scheduleThe goal isn't to replace your doctor. It's to prepare you for the conversation, and to be the nudge that gets you to actually book that colonoscopy or mammogram you've beeMar 3, 2026 2:02 PM

Ask HN: How are you structuring Markdown-based context for AI coding agents?https://news.ycombinator.com/item?id=47231386I’ve recently transitioned from using LLMs in-browser to a local agentic workflow in VS Code (Gemini Code Assist). I can approve/disapprove changes which is nice, but I’ve hit a wall regarding context management. Initially, I provided all the whole repo as context to the non-agentic version of Gemini code assist and it performed well.I read the agentic mode is "better" so to keep the agent aligned with my project's architecture, I’ve manually built 7 dense Markdown files that serve as the system instructions for the project. I require Gemini to update these files as we implement features.gemini.md (instructs gemini to read the other md files and handle updating) project_overview.md, architecture.md, features.md, database.md, api.md, security.mdEach file is between 500–1,500 words so I’m concerned if f this is the right way to go. There seems to be no consensus on context file best practices. I’m seeing strong arguments for both minimalist, lean instructions and dense, project-wide specMar 3, 2026 12:29 PM

Show HN: AgentThreads – Stack Overflow for AI Agentshttps://agentthreads.devI was listening to a recent YC podcast about "build something agents want", and while building apps with Claude Code, I kept running into trouble figuring out how APIs actually behave in practice. And knowing that most companies won't update their docs to be agent-friendly, it clicked — agents need their own Stack Overflow.AI agents are consuming APIs at a scale and speed that human-written documentation can't keep up with. AgentThreads is a community directory where agents discover, submit, and review APIs — for agents, by agents.The idea came from watching agents fail silently on undocumented edge cases, relying only on Google searches and bad docs. They need structured, community-maintained knowledge they can query at runtime.A few things we built:- API directory with agent-written reviews and ratings- No UI, just REST — built for agents, not humans- Anti-spam verification (agents solve reasoning challenges, not CAPTCHAs)- Karma system so agents build reputation over timeBuilt mostlMar 3, 2026 11:11 AM

Show HN: btrc – C, but better. Built with AI in just a few weeknightshttps://github.com/schiffy91/btrcbtrc is a statically-typed language that transpiles to C11. It adds classes, generics (monomorphized), type inference, lambdas, f-strings, collections (Vector, Map, Set), threads, GPU compute via WebGPU, ARC memory management, exception handling, and a standard library — while generating strict C11 with no runtime, no GC, and no VM.The compiler is a 6-stage Python pipeline (lexer → parser → analyzer → IR gen → optimizer → C emitter) driven by a formal EBNF grammar and an algebraic AST spec (Zephyr ASDL). The generated C is readable and linkable with any C11 compiler. It ships with a VS Code extension (LSP with completions, diagnostics, go-to-def, hover) and 930 tests.I've wanted to build something like this for about 10 years, but it was always too ambitious of a project to do on the side. With AI, I was able to build it over a handful of evenings after work, which is really wild.Some things worth noting:A few things that I find fun / interesting / noteworthy:- The EBNF grammar and ASDMar 2, 2026 5:52 PM
