Show HN: I built a site that maps the web from a bounty hunter's perspective https://ift.tt/MJrz1xT

Show HN: I built a site that maps the web from a bounty hunter's perspective I built this because I wanted my own directory of public companies running bug bounty programs — where I could see their infrastructure in one place and have a real idea of where to start poking holes. Neobotnet collects intel data from companies on HackerOne and Bugcrowd — subdomains, DNS records, web servers with status codes, indexed/crawled URLs, JS files, and exposed secrets/paths (still building this last part). The data is already there when you need it. No scans to run. Currently tracking 41 companies, 63,878 web servers, and 1.8M+ URLs. Long term I want to expand this to startups that depend on cloud infrastructure so they can see what's publicly accessible. Made a free sample with Capital One's data (and other companies) so you can see what it looks like without signing up: https://freerecon.com Original Page: https://neobotnet.com Feedback very welcome. https://ift.tt/l4hLMRK March 24, 2026 at 01:49AM

Show HN: Jelly – SSH Social Hangout https://ift.tt/JAlxHuD

Show HN: Jelly – SSH Social Hangout built a social network you connect to over SSH. no signup, no browser, just open your terminal and you're in. channels, profiles, guestbook, shared blackboard, Top 8. your identity is your SSH key fingerprint so no passwords needed. to connect: ssh-keygen -t ed25519 (just hit enter through all the prompts) ssh jellyshell.dev built with Go, Bubble Tea, and Wish. i wanted to make something that maintains privacy and gets away from the brain rot and algorithms pushing rage bait. lmk what you think.

Show HN: JulIDE – Lightweight Julia IDE Built with Tauri https://ift.tt/CL9i05c

Show HN: JulIDE – Lightweight Julia IDE Built with Tauri Hi HN! I built JulIDE - a lightweight Julia IDE using Tauri and Rust. Features: 10MB install (vs VSCode's 300MB) Full LSP, debugger, Git integration Built-in dev containers with X11 forwarding Tauri/Rust backend, React frontend Monaco based editor It's beta but functional. Built this for fun and to solve a real need in the Julia community. Tech stack: Tauri 2, Rust, React, Monaco, LanguageServer.jl GitHub: https://ift.tt/NzVKsSM Would love feedback! https://ift.tt/NzVKsSM March 24, 2026 at 12:55AM

Show HN: Minimalist library to generate SVG views of scientific data https://ift.tt/WVSQ2s7

Show HN: Minimalist library to generate SVG views of scientific data Just wanted to share with HN a simple/minimal open source Python library that generates SVG files visualizing two dimensional data and distributions, in case others find it useful or interesting. I wrote it as a fun project, mostly because I found that the standard libraries in Python generated unnecessarily large SVG files. One nice property is that I can configure the visuals through CSS, which allows me to support dark/light mode browser settings. The graphs are specified as JSON files (the repository includes a few examples). It supports scatterplots, line plots, histograms, and box plots, and I collected examples here: https://ift.tt/LzWSibD... I did this mostly for the graphs in an article in my blog ( https://alejo.ch/3jj ). Would love to hear opinions. :-) https://ift.tt/0VPA8k5 March 24, 2026 at 12:54AM

Show HN: Threadprocs – executables sharing one address space (0-copy pointers) https://ift.tt/6B9ZybA

Show HN: Threadprocs – executables sharing one address space (0-copy pointers) This project launches multiple independent programs into a single shared virtual address space, while still behaving like separate processes (independent binaries, globals, and lifetimes). When threadprocs share their address space, pointers are valid across them with no code changes for well-behaved Linux binaries. Unlike threads, each threadproc is a standalone and semi-isolated process. Unlike dlopen-based plugin systems, threadprocs run traditional executables with a `main()` function. Unlike POSIX processes, pointers remain valid across threadprocs because they share the same address space. This means that idiomatic pointer-based data structures like `std::string` or `std::unordered_map` can be passed between threadprocs and accessed directly (with the usual data race considerations). This accomplishes a programming model somewhere between pthreads and multi-process shared memory IPC. The implementation relies on directing ASLR and virtual address layout at load time and implementing a user-space analogue of `exec()`, as well as careful manipulation of threadproc file descriptors, signals, etc. It is implemented entirely in unprivileged user space code: < https://github.com/jer-irl/threadprocs/blob/main/docs/02-imp... >. There is a simple demo demonstrating “cross-threadproc” memory dereferencing at < https://github.com/jer-irl/threadprocs/tree/main?tab=readme-... >, including a high-level diagram. This is relevant to systems of multiple processes with shared memory (often ring buffers or flat tables). These designs often require serialization or copying, and tend away from idiomatic C++ or Rust data structures. Pointer-based data structures cannot be passed directly. There are significant limitations and edge cases, and it’s not clear this is a practical model, but the project explores a way to relax traditional process memory boundaries while still structuring a system as independently launched components. https://ift.tt/4oKiJCI March 23, 2026 at 11:08PM

Show HN: MAGA or Not? Political alignment scores for people and companies https://ift.tt/ptnz84v

Show HN: MAGA or Not? Political alignment scores for people and companies I wanted a way for people to support companies and people that align with their political beliefs. Additionally, I think it can serve as a valuable, source-linked public ledger of who said and did what over time, especially as incentives change and people try to rewrite their positions. This is fully AI-coded, researched, and sourced. Additionally, AI helped develop the scoring system. The evidence gathering is done by a number of different agents through OpenRouter that gather and classify source-backed claims. The point of that is not to pretend bias disappears, but to avoid me manually selecting the evidence myself. I intend for it to remain current and grow. The system is close to fully automated, though ongoing evidence collection at scale is still limited mostly by cost. The name is an homage to the early days of Web 1.0 and Hot or Not, which was a main competitor of mine as the creator of FaceTheJury.com, but I think it works well here. The backend and frontend are running on Cloudflare Workers with D1. It's coded in vanilla JavaScript. https://magaornot.ai March 23, 2026 at 12:55AM

Show HN: Revise – An AI Editor for Documents https://ift.tt/Vy8AdOX

Show HN: Revise – An AI Editor for Documents I started building this 10 months ago, largely using agentic coding tools. I've stayed very involved in the code base and architecture, and have never moved faster in my life as a dev. The word processor engine and rendering layer are all built from scratch - the only 3rd party library I used was the excellent Y.js for the CRDT stack. Would love some feedback! https://revise.io March 22, 2026 at 08:28PM

Show HN: Fossilware – a community archive of retro hardware, software, and games https://ift.tt/MAyFrbS

Show HN: Fossilware – a community archive of retro hardware, software, and games i built a small site to collect memories of the things we grew up with: floppy drives, Game Boys, cassette tapes, forgotten software, classic games. the tech stack is React, Supabase and Vercel. fair warning: the items on there right now were seeded by AI to get things started. the goal is for it to grow through community submission. there's a submit form, no account needed. i'd love to gather some early feedback and get some more ideas. something i was thinking about in the future is having users create accounts to favorite items and comment their own personal experiences with items. right now everything requires manual approval but in the future i'd like to push that towards the community. thanks for looking! https://ift.tt/GoRYJX5 March 21, 2026 at 12:33AM
