Products that do what Securday – An Anonymous Natural Language Network/OSI Mapper does
Hello HN! I'm Joshua Herman, and I'm excited to introduce to HN Securday – an innovative Anonymous Natural Language Network and OSI Mapper. Securday is accessible in two distinct ways: through the website at [Securday](https://www.securday.com) and via a dedicated SMS phone line at [+1 (825) 251-9142](tel:8252519142), which offers enhanced anonymity. I had the opportunity to present Securday at Defcon 31, where it received an overwhelmingly positive response. One of the most fascinating aspects I discovered during the presentation was the system's remarkable capabilities. For…

Hey HN! I just published https://meet.hn, a map to find hackers in your city. How it works? Demo of the signup process: https://x.com/meet_hn/status/1834918518904746329 1. Fill the form: username, city+country 2. Copy the text generated in the box below the form, and paste it in your HN description. 3. Click "Add me on the map" Optionnaly (it's recommended!) you can add links to your socials as well as some tags to showcase your interests. Why does it exist? I created this because, despite its harsh reputation on the internet, I love the HN community. I…

I made a HN client that allows you to explore comments in a breadth-first manner. Compared to the classic depth-first approach, it works much better for the larger threads - you don't lose the context and can easily skip discussions you're not interested in.

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 :)

hey guys, wanted to show one of my side projects i just made public. the idea is basically another osint tool for pentesters and bug bounty hunters. it watches certificate transparency logs and checks newly-seen domains for exposed stuff like .env files, open .git dirs, config files, db dumps and so on, and puts whatever it finds into a searchable db. you just search a domain (or part of one) and see what's exposed. it's read-only and free. one thing i've been thinking about adding is a way to register for certain keywords and get notified when something new shows up for that search. would…

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…

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…

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…

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…

Needed this in my own work, anonymizing PII/PHI and decided to build this because presidio didn't really cut it for our use-case. Try it and maybe let me know if you have any feedback :)

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…

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. Don't be afraid to hurt my feelings; this was put together in less than 4 hours to see if I…

Hi everyone, I read HN every day, but there was always more great content than I had time to read. I know there are already several HN summarizers on GitHub, and I tried some of them. They just didn't fit the workflow I wanted, so I decided to build my own. My project is a self-hosted app that automatically fetches top stories, summarizes them with AI, translates them into your preferred language, and prepares a personalized daily briefing in a nice customizable UI while you sleep. Maybe I'm not the only one who wanted this kind of workflow. I'd love to hear your thoughts, especially on what…

Hello HN. I'm Maxime, founder at LimaCharlie (https://limacharlie.io), a Hyperscaler for SecOps (access building blocks you need to build security operations, like AWS does for IT). We’ve engineered a new product on our platform that solves a timely issue acting as a guardrail between your AI and the world: Viberails (https://www.viberails.io) This won't be new to folks here, but we identified 4 challenges teams face right now with AI tools: 1. Auditing what the tools are doing. 2. Controlling toolcalls (and their impact on the world). 3. Centralized management. 4. Easy…

Hello. I made this project as an experiment in using key cryptography for user identity in a client server model, and for some future peer to peer projects that I am working on. I am looking for feedback, please let me know what you think. Also, Merry Christmas to HN! :-)

Hello HN! Here's my November Startup Sprint project (coded in two days). http://hackerlunch.com It allows you to post your lunch plans and lets other hackers join you. I built this because I often see HN users are interested in meeting each other if they are in the same area. I am not a coder, so this version is very rough. If people use it, I will work with others to build a more polished version. I would love some feedback. What do you think? Is this something you will be using?

Hello, for some time I've been developing this project now that I am happy that it finally can see the light. I love Tor, but I believe the biggest thing with Tor is that the nodes are strangers which in itself requires some sort of level in just that, complete strangers. For this reason, I decided to build this private network inspired by the Onion router. Unlike other public networks, GiralNet is not for anonymous connections to strangers. It is built for small teams or groups who want privacy but also need a level of trust. It assumes that the people running the nodes in the network are…

Hi HN, I want to share a story that might resonate with anyone who has tried to launch an open-source project from zero visibility, zero budget, zero network. Seventy days ago I created a repo called WFGY. I had no prior followers, no launch partners, no ads. Today, it’s at 800 stars and counting. Pure cold start. The “secret”? Not marketing. Not tricks. It was building a Problem Map. --- #### What is a Problem Map? Instead of claiming my system “improves reasoning” or “solves RAG bugs,” I wrote down 16 concrete failure modes engineers hit every day: * Embedding drift (semantic ≠ vector…
