Hi HN I built mdto.page because I often needed a quick way to share Markdown notes or documentation as a proper webpage, without setting up a GitHub repo or configuring a static site generator. I want...
I am a student and co-founder of an accessibility startup. Balancing product development with exams broke my workflow, so I looked for a debugger. Mathematica Successūs is my attempt to model the "Sel...
Hi! I've built this because I kept reaching for Celery for simple scheduled tasks and it felt like overkill. I just needed "run this function every hour" or "daily at 9am", not distributed workers. So...
Hey HN, Got tired of how bloated GitHub became- copilot everywhere, janky JS, slow loads. So I built GitClassic, a read-only GitHub interface that's pure server-rendered HTML, kind of like old.reddit....
i've been working with healthcare/biobank data and keep thinking about what "data moats" mean now that llms can ingest anything. some a16z piece from 2019 said moats were eroding — now the question se...
Hi HN, I recently noticed a recurring visual artifact in the "Most Replayed" heatmap on the YouTube player. The highest peaks were always surrounded by two dips. I got curious about why they were ther...
Hi HN, I built *Sightline*, a Shodan-style search engine for *physical-world infrastructure*. Shodan makes it easy to explore exposed internet services. Sightline applies the same idea to the real wor...
I built an unofficial CLI and MCP server for Lambda cloud GPU instances. The main idea: your AI agents can now spin up and manage Lambda GPUs for you. The MCP server exposes tools to find, launch, and...
For the past year I've been working to rethink how AI manages timing in conversation at Tavus. I've spent a lot of time listening to conversations. Today we're announcing the release of Sparrow-1, the...
Hi HN, I built Ayder — a single-binary, HTTP-native durable event log written in C. The wedge is simple: curl is the client (no JVM, no ZooKeeper, no thick client libs). There’s a 2-minute demo that s...
I built NukeCast because I’ve always wanted a tool that answers one question fast. If it happened today, where would the fallout plumes go and where would you drive to get out of it. NukeCast uses wea...
It turns out the inverse of the Hessian of a deep net is easy to apply to a vector. Doing this naively takes cubically many operations in the number of layers (so impractical), but it's possible to do...
Hi HN — I built Microwave, a native iOS app for browsing and posting short-form videos, similar to TikTok, but implemented as a pure client on top of Bluesky / AT Protocol. There’s no custom backend: ...
Hey HN! I built Retain as the evolution of claude-reflect (github.com/BayramAnnakov/claude-reflect). The original problem: I use Claude Code/Codex daily for coding, plus claude.ai and ChatGPT occasion...
Hi HN, I built an open-source AI agent that has already indexed and can search the entire Epstein files, roughly 100M words of publicly released documents. The goal was simple: make a large, messy cor...
Hey HN, this is a small Haskell learning project that I wanted to share. It's just a website where you can see how many people write the exact same text as you (thought it was a fun idea). It's built ...
OP here. I spent the weekend red-teaming small-scale open weights models (Qwen2.5-1.5B, Qwen3-1.7B, Gemma-3-1b-it, and SmolLM2-1.7B). I found a consistent vulnerability across all of them: Safety alig...
I've always loved RTS games and wanted to make a game similar for a long time. I thought I'd just try and build a mini / puzzle game around the resource gathering aspects of an RTS. Objective: You hav...
Basically was getting annoyed jumping between 5 different sites during this winter storm season, so I built "StormWatch". It's a no-fuss, mobile-friendly webpage (dashboard) that shows all the stuff I...
Author here. This came out of debugging a real Rails app running in a FIPS enabled container. Everything looked correct. OpenSSL 3 with the FIPS provider enabled. Ruby built against it. A simple pg co...
