Show HN: I built a tool for free PDF Resume (CV) hosting – wanna test it? If you are job hunting and you need to host your PDF resume in a professional way, without ads or weird limits, I built Resume.hr . You can upload a resume and write or upload a cover letter. You can add links from other social media profiles, and a QR code is generated automatically. The design is clean and you can even add credentials Linkedin style. You can share your resume in a subdomain like your-name.resume.hr/resume an example I created is https://ift.tt/lzK9asB . We added a tool inside call Activities that you can use to track job-hunting activities, like to whom you sent the resume and follow-ups, and mostly track interaction to help with the job finding. Why I built this? We have another tool where users can share PDF files online but that is made for documents mostly, and the design is for that. Even so, users upload and share their resumes there, so I belive there is a place for such a tool. We are s...

Show HN: I built a system to drive my RC car from anywhere in the world Wanted to share a project I've been working on. Basically lets you drive an RC car remotely over the internet with live FPV video. I'm arranging outdoor time attack tournaments with friends, somewhere in woods or in the open field. The setup: - Raspberry Pi Zero 2W mounted on the car with a wide-angle camera - ESP32 on the transmitter generating joystick voltages (needed because ARRMA's 2-in-1 ESC/receiver has no accessible inputs) - Cloudflare for the networking magic (TURN, Tunnel, Workers) - Browser-based controls - works on phone or desktop What it does: - ~100-200ms control latency over internet (10-15ms on LAN) - 720p @ 30fps live video - Touch controls on mobile, keyboard on desktop - Admin dashboard for race management - Token-based access so I can let friends drive - Auto-stops if connection drops (safety first) - Adjustable throttle limits - Optional re-streaming to YouTube Built it because I ...

Show HN: Pipenet – A Modern Alternative to Localtunnel Hey HN! localtunnel's server needs random ports per client. That doesn't work on Fly.io or behind strict firewalls. We rewrote it in TypeScript and added multiplexing over a single port. Open-source and 100% self-hostable. Public instance at *.pipenet.dev if you don't want to self-host. Built at Glama for our MCP Inspector, but it's a generic tunnel with no ties to our infra. https://ift.tt/J9rRuoI https://pipenet.dev/ January 19, 2026 at 11:10PM

Show HN: Available.dev – Craigslist for Developer Availability Hey HN, Craigslist for developer availability. You're either in the room or you're not. How it works: GitHub OAuth → one-liner → pick skills → you're visible. Employers browse freely, reach out directly. Design choices: - Most recently active at top (browsing keeps you visible) - Days cap at "30+" (no one needs to see "day 47") - No resumes, no applications 54 devs in the room. Supply side works. Testing demand. Question for HN: Would you actually browse this when hiring? What's missing? https://ift.tt/fGNSZOn January 18, 2026 at 11:01PM

Show HN: I built a "sudo" mechanism for AI agents Hi HN, I’m Yaron, a DevOps engineer working on AI infrastructure. I built Cordum because I saw a huge gap between "AI Demos" and "Production Safety." Everyone is building Agents, but no one wants to give them write-access to sensitive APIs (like refunds, database deletions, or server management). The problem is that LLMs are probabilistic, but our infrastructure requires deterministic guarantees. Cordum is an open-source "Safety Kernel" that sits between your LLM and your execution environment. Think of it as a firewall/proxy for agentic actions. Instead of relying on the prompt to "please be safe," Cordum enforces policy at the protocol layer: 1. It intercepts the agent's intent. 2. Checks it against a strict policy (e.g., "Refund > $50 requires human approval"). 3. Manages the execution via a state machine. Tech Stack: - Written in Go (for performance and concurrency)....

Show HN: DailySpace – Daily astronomy photos with rocket launch tracking I built DailySpace because I wanted a better way to explore space imagery beyond endlessly scrolling through search results. The app features a curated collection of thousands of cosmic images organized into categories like galaxies, nebulae, Mars, and black holes. Each photo comes with explanations that make the science accessible. I recently added rocket launch tracking with detailed mission data from space agencies worldwide. The architecture focuses on discoverability-you get a featured photo daily, but you can also browse categories or search the full collection. The dark-themed UI is optimized for viewing space imagery without eye strain.Free tier covers daily photos and basic browsing. Premium unlocks unlimited search results, unlimited favorites, and cross-device sync. What started as a personal project to learn more about astronomy turned into something I use every day. The two-minute daily habit of openi...
