Show HN: Eimi – Turn any information into daily cards Hi HN, I’m the developer behind Eimi ( https://eimi.tech/ ). The Problem: I found myself constantly distracted. I wanted to learn new words and keep up with specific news, but every time I opened an app, I ended up doomscrolling for 20 minutes. The signal-to-noise ratio was too low. The Solution: I built Eimi to "calm down" my consumption. It’s a card-based app that delivers content depends on your personal needs. Instead of an infinite feed, you get curated highly customizable cards. Use Cases: Language Learning: Instead of flashcards without context, it generates cards with usage examples for words I'm trying to learn. News/Market Watch: I hook up my interests (e.g., tech news, specific stocks), and it generates a summary card. No clickbait, just the gist. It's currently in Public Beta. I’d love to hear your thoughts on the UX and what other "card types" you’d find useful. Thanks! https://eimi.tech Dece...

Show HN: Paper Tray – dramatically better file organization for Google Drive Hi HN, I'm a solo founder working on a project that uses AI to help with finding files in Google Drive. The Problem: With Google Docs and Sheets, it's easy to make documents but very hard to find them again unless you organize them manually, which takes time. This is a big problem for startups, who often use Google Docs for the convenience but struggle with information management. It leads to a lot of time wasted searching for documents and a lack of clarity. The Solution: Paper Tray uses AI to organize Drive files automatically. It 'tags' each file so you can then use a filter interface to find them. By default, it tags by the type of document (meeting notes, plan, pitch deck etc), the topic of the document, and the department it belongs to (product, engineering, sales etc). The result is that it takes just a few seconds to find most of your documents, in an intuitive and satisfying way. You c...

Show HN: Aroma: Every TCP Proxy Is Detectable with RTT Fingerprinting TL;DR explanation (go to https://ift.tt/35bSzuM... if you want the formatted version) This is done by measuring the minimum TCP RTT (client.socket.tcpi_min_rtt) seen and the smoothed TCP RTT (client.socket.tcpi_rtt). I am getting this data by using Fastly Custom VCL, they get this data from the Linux kernel (struct tcp_info -> tcpi_min_rtt and tcpi_rtt). I am using Fastly for the Demo since they have PoPs all around the world and they expose TCP socket data to me. The score is calculated by doing tcpi_min_rtt/tcpi_rtt. It's simple but it's what worked best for this with the data Fastly gives me. Based on my testing, 1-0.7 is normal, 0.7-0.3 is normal if the connection is somewhat unstable (WiFi, mobile data, satellite...), 0.3-0.1 is low and may be a proxy, anything lower than 0.1 is flagged as TCP proxy by the current code. https://ift.tt/neOoxhd December 26, 2025 at 03:34AM

Show HN: Neko.js, a recreation of the first virtual pet Hi HN, Here is a late Christmas present: I rebuilt Neko [1], the classic desktop cat that chases your mouse, as a tiny, dependency-free JavaScript library that runs directly on web pages. Live demo: https://louisabraham.github.io/nekojs/ GitHub: https://ift.tt/dOM3kNp Drop-in usage is a single script tag: This is a fairly faithful recreation of Neko98: same state machine, same behaviors, same original 32×32 pixel sprites. It follows your cursor, falls asleep when idle, claws walls, and you can click it to cycle behavior modes. What made this project interesting to me is how I built it. I started by feeding the original C++ source (from the Wayback Machine) to Claude and let it "vibe code" a first JS implementation. That worked surprisingly well as a starting point, but getting it truly accurate required a lot of manual fixes: rewriting movement logic, fixing animation timing, handling edge cases the AI missed, etc. My ...

Show HN: A solar system simulation in the browser I didn't realize Universe Sandbox ran on MacOS, and I was in the mood to play around a bit. Some functions it's got: - Random system generation - Sonification is super fun too - Habitability Simulation (Just for fun, don't cite this please) - Replacing, spawning, deleting objects I've had tons of fun building this, so I hope someone else can share the joy. It's free and runs in the browser. I'd love to hear any feedback. I think this is at a state where I might leave it as it is, but if people are interested in other features, maybe I'll keep working on it. I've kept saying I'll stop working on this for a while now though. https://ift.tt/wyNb6V3 December 30, 2025 at 12:34AM

Show HN: MiddleViewer – A native macOS app for technical interview feedbacks Hi HN, I built a native macOS app for helping interviewers for writing feedbacks. It listens to realtime conversations, takes the code, you can add your custom rules and BOOM, it will write the feedbacks in a way you want. https://middleviewer.in December 29, 2025 at 11:21PM
