Show HN: Labspace Directory – Biotech resource for lab space Hi HN, I’m Elijah with Labspace Directory ( https://bit.ly/3K2BUEA ), a new platform designed to help biotech companies find lab space. Our site brings together available lab space across the Bay Area, serving startups through established life science companies. The platform is built to streamline the search process—saving time by centralizing listings, providing key details on availability, and helping companies connect directly with opportunities that fit their needs. You can get started here: https://bit.ly/3K2BUEA We’re excited to share this with the broader Bay Area life science community and welcome any feedback as we continue to build and improve the platform. https://bit.ly/3K2BUEA September 15, 2025 at 11:52PM

Show HN: PaperSync, making ArXiv papers collaborative Demo: https://youtu.be/pnznDL9SZvI PaperSync was a project was made by two CS freshmen, Matthew Li (me!) and Michael Li, in 24 hours during HackCMU. At a high level, we built PaperSync to make reading research papers easier and more collaborative. Users can reference any part of the paper, ask anything they want, and have other users reply, all within the paper itself! If you are interested in our work, we would love to talk!

Show HN: MemoryMe: An effort to beat Cognitive Decline Hi everyone! First time posting. I built this mini memory game in an attempt to beat lazy memory syndrome. because when was the last time you remembered what you did the day before purely based on memory (or without being prompted) ? Super simple fun game for giving our brains a quick workout and actually reminding it on how to remember. If you had those old Nokia phones from the early 90s, the game will seem insanely familiar to you https://bit.ly/47BT6KS September 13, 2025 at 08:35PM

Show HN: Flo Is a Rust/Vulkan 3D Renderer for the Bevy Game Engine https://bit.ly/4meW37J

Show HN: Flo Is a Rust/Vulkan 3D Renderer for the Bevy Game Engine I’m using the excellent Bevy game engine for my colony sim/action game, but I do lots of real-time procedural generation/animation so the wgpu renderer is too slow. So I wrote my own Rust/Vulkan renderer and integrated it with Bevy. It’s ugly, buggy, and hard to use but multiple times faster. Full source code, with 9 benchmarks comparing performance with the default wgpu renderer: https://bit.ly/3Imcdya Video where I go over the examples and run them on the Steam Deck: https://www.youtube.com/watch?v=y1m30oOksmI https://bit.ly/3Imcdya September 13, 2025 at 02:33AM

Show HN: VibeDbg – Cconversational, LLM-Powered AI Assistant for WinDbg Transforms debugging with WinDbg into a conversational, LLM-assisted experience. Instead of memorizing cryptic commands, you can interact with the debugger using natural language: such as show me all the handles opened by this process, list enabled token privileges etc. It includes: A native WinDbg extension for command execution An AI-driven MCP server that bridges debugging tasks with powerful language models Integrated support for WinDbg features like breakpoints, memory views, and the dx visualization command Any improvement suggestions? https://bit.ly/3VNkKNK September 12, 2025 at 11:50PM

Show HN: Polaris Audit – Website Compliance Scanner with Fix Instructions https://bit.ly/4gkOrPR

Show HN: Polaris Audit – Website Compliance Scanner with Fix Instructions I built Polaris Audit to help small businesses fix website issues that were costing them customers. It scans your website for: - Security problems (HTTPS, SSL, headers) - GDPR compliance issues (cookies, privacy policy) - Accessibility problems (alt text, headings, keyboard navigation) The key difference: Instead of just telling you what's wrong, it gives you copy-paste code to fix it. Example: Missing page title Fix: Add to your Time: 2 minutes Tech: Django + React + PostgreSQL. Built because most compliance tools just point out problems without showing how to fix them. Try it: polarisaudit.com Currently free with detailed reports. Let me know if you want to try a paid account for free, and I'll help you set it up. What do you think? Would love feedback on the approach. September 12, 2025 at 02:19AM

Show HN: Newlang.app – Practice EN, ES, PT, FR, IT, DE Hi HN, I built newlang.app because I wanted a simple way to improve my spoken English. Most tools I found were either focused on grammar, full of distractions, or not free. So I created something minimal that I could use daily: Listen → Repeat → Read → Speak It started as a personal project, but since it worked for me, I decided to share it. Right now it supports English, Spanish, Portuguese, French, Italian, and German. A few notes: • It’s completely free. • I don’t collect user data. • The only thing required is a valid email to create an account. I’d really appreciate feedback from this community — especially on usability, language content, and how it could be improved for learners.

Show HN: I built a minimal Forth-like stack interpreter library in C https://bit.ly/46xY8qE

Show HN: I built a minimal Forth-like stack interpreter library in C This weekend I created stacklib.h - a single-header library that brings Forth-style stack operations to C. It implements a basic interpreter with: - Stack operations (push/pop/dup/swap/over/drop) - Arithmetic (+, -, *, /) - Output (., emit, cr) - Stack inspection (.s, depth) Example usage: Stack s; stack_init(&s); dict_init(); exec(&s, "10 20 + ."); // Prints "30" exec(&s, "1 2 3 4 .s"); // Shows stack contents The library is self-contained, requires no dependencies, and handles basic error checking. It was inspired by wanting to understand how Forth works at a fundamental level while keeping the simplicity of C. I'm curious what other stack-based or concatenative programming enthusiasts think about this approach. Has anyone else built something similar? What features would you add to make it more useful?

Show HN: I made a script that gives me fake calls to escape boring moments https://bit.ly/4gi7Xwd

Show HN: I made a script that gives me fake calls to escape boring moments I built a little script that gives me a fake phone call to escape boring and awkward situations. I bought a virtual number from twilio and saved it as one of my relatives. Whenever I feel stuck, I just tap a button called “ESCAPE” on my phone. It sends a request to my remote server. The server runs a small Python script which schedules an actual call. After a minute, my phone rings and plays a pre-recorded audio. I simply say “sorry, I’m getting a call” and walk away. A tiny project, but it has saved me so many times. Script - https://bit.ly/46bfaJP September 11, 2025 at 12:07PM

Show HN: Enter a Topic, receive a language learning curriculum with videos https://bit.ly/3Kf6QBo

Show HN: Enter a Topic, receive a language learning curriculum with videos Hi HN, I've built this for use in a language learning app, but you can use it without an app, since it's based around Youtube videos. The main idea is to give you a structured learning plan with content that you care about, to keep you engaged. I know it's hard to stay on track when learning a language, so I'm hoping this will help people stay consistent and build a habit. I was surprised yesterday when one user entered "rugby and food" as their interest (learning French), and the first video is actually a video about rugby AND food in French. There's no limit to the breadth of content on Youtube! (Although I have to admit, it is a bit lucky that this exact video exists) https://bit.ly/466JhSA Hope you find it interesting! https://bit.ly/46kMXAp September 11, 2025 at 09:29AM
