   Using stylometry to find HN users with alternate accounts▲676

   Author here. This site lets you put in a username and get the users with the most similar writing style to that user. It confirmed several users who I suspected were alts and after informally asking around has identified abandoned accounts of people I know from many years ago. I made this site mostly to show how easy this is and how it can erode online privacy. If some guy with a little bit of Python, and $8 to rent a decent dedicated server for a day can make this, imagine what a company with millions of dollars and a couple dozen PhD linguists could do. Here's Paul Graham:…

   Viberia▲146

   Hey HN, This is my take on the agent harness. Everything on an isometric map. Agents are grouped into "buildings" that run in a sequence or a loop; e.g., the CodeForge has an agent that writes a PRD, another one that implements, and a third that reviews. Everything is customizable, you build your own buildings/teams however you want. It's a Tauri app, really light (about 8x less energy than the closest competitor I benchmarked, so it actually runs from a coffee shop on battery). It's macOS only for now, but ping me if you are willing to test the Windows or Linux version. I've been…

   An Elliptic Curve-Based Secure Chat, Written Using Rust and Protobuf▲66

   This is a project I made to learn more about crypto. I've also written a [post](https://vaktibabat.github.io/posts/ecurvechat/) that explains all the crypto concepts and algorithms used in the project, and how I implemented them. I'd be very glad for any feedback about both the code and the post :)

    Securly - Keep your kids safe on your home network▲17

    http://www.securly.com To keep kids safe online, we felt it wasn’t enough anymore to rely simply on blocking websites (domain filtering). We also need to protect them on trusted social media sites like Facebook, YouTube and Wikipedia. We couldn’t find any solution that does this for the entire home network. We are two security hackers who have worked in the enterprise firewall space for several years and felt this was an important problem to solve. The video on our front page gives you a pretty good idea of what we do. You can also use us as a free premium DNS server by pointing your DNS to…

    Hoodmaps Meets 4chan▲8

    I made this as a pair programming exercise with o1-preview. o1 did most of the heavy lifting, through high level prompts, but eventually I needed to diverge from it to get to completion. My initial prompt was: --- I'm making a web app: It's like 4chan, but each thread starts with a gps coordinate. People can only post text and images. I want to build it with flask and sqlalchemy. I want just the backend and data model that supports these threads, anonymous users, and users that can register a permanent username. Write as much of it as you can for me. --- This produced a fully scaffolded…

    A thin Python library to access HN data using Algolia's API▲15

    Hello community. Some time ago I was trying to create a project for my students using Hacker News data. As you might know, HN offers an official API [0], but it's based on Firebase and I felt it's main usage is to build clients, rather than consult data. I found out that Algolia also provides an official REST API [1]. It's exactly what I needed: the ability to "search" HN. Either by keywords, type of stories (Show HN, Ask HN, etc) and/or date. So I created a thin python wrapper on top of Algolia's Search API: https://github.com/santiagobasulto/python-hacker-news The…

    Chatroulette Spy▲8

    I have just launched a project that has been sitting on my hard drive 80% finished for the better part of a year. http://www.chatroulettespy.com It detects your 'anonymous' chat partner's IP address and performs a geolocation lookup on it to show the user the partner's approximate location on a map. I know the Chatroulette fad has peaked a long time ago (when I started this project), but there are still many people using it and its many clones. It was important for me to follow through on this one and not let it die on my hard drive like many projects before. I would appreciate any feedback…

    RAG-Guard: Zero-Trust Document AI▲9

    Hey HN, I wanted to share something I’ve been working on: *RAG-Guard*, a document AI that’s all about privacy. It’s an experiment in combining Retrieval-Augmented Generation (RAG) with AI-powered question answering, but with a twist — your data stays yours. Here’s the idea: you can upload contracts, research papers, personal notes, or any other documents, and RAG-Guard processes everything locally in your browser. Nothing leaves your device unless you explicitly approve it. ### How It Works - * Zero-Trust by Design*: Every step happens in your browser until you say otherwise. - * Local…

    NICH: GPT Anonymizer▲14

    I built NICH after realising I couldn't use ChatGPT for my conflict research work without risking data leaks. It's a browser extension that: - Anonymises names, emails, and addresses in one click - Preserves context for AI to understand - Restores original data in AI responses - 100% browser-based (no cloud, data never leaves your device) Built it for researchers, lawyers, HR professionals or simply anyone handling confidential data who wants AI assistance without compliance nightmares. Free to use: https://www.nichtech.uk Would love feedback from the HN community!

    secinsights.ai – An open-source full-stack app using LlamaIndex▲7

    Hi HN, A few weeks ago, we stealth launched SEC Insights on Product Hunt and were thrilled to reach the top 5! What is SEC Insights? It harnesses the Retrieval Augmented Generation (RAG) capabilities of LlamaIndex to provide answers about SEC 10-K & 10-Q documents. The enthusiastic reception we received on Product Hunt prompted us to open-source our project. Now, developers can use our project either as a reference or they can fork it entirely for their LLM-powered applications. We at LlamaIndex built this to help developers move their LLM app ideas from prototype to production. We're very…

    Hi hackers, long time reader, first time "real" submitter. This is by no means a revolutionary idea, or even execution, but rather something I've always wanted to do, just to see if I could write a good implementation of it. So without further adieu: http://ca.pitali.st/ Yes, it's just an URL shortener. Please check out the API and if there anything you like about it, please share, so I can take this feedback with me to my future projects. If there's something you REALLY hate, that's feedback too.
