Show HN: Domvault – self-hostable second brain with consent-based note sharingHi HN, wanted to translate this into a more human-readable post - please see below and would love any and all feedback!What is it: A second brain you self-host and engine to compound itself and spark new ideas, from your own ideas.Why: ROI on your own knowledge, actually realize the value from your ideas. Down the line I'd love for this to evolve into a wider / shareable concept -- Haven't fully figured this out yet which is part of the reason I am posting. View the /constellation folder for the specs on that concept. (Self hosting engine is all in the repo as well)Looking forward to hearing from anyone!

Show HN: ProtoWall – NDA wall and reverse proxy for sharing prototypesI built ProtoWall to solve a problem I kept running into: needing to share a working prototype with an investor or client, but not wanting to just hand out a URL with no protection.ProtoWall sits as a reverse proxy in front of your app. You invite reviewers by email, they click a link, read and sign a versioned NDA, and then get proxied through to your prototype. No SDK, no code changes on your end.How it works:- You add your prototype's origin URL and configure an NDA - Invite specific people by email; they get a one-click link - Reviewer accepts the NDA (name, timestamp, IP, user agent all recorded) - A 30-day proxy session is created; traffic flows through to your app - You can revoke access instantly; the session terminates immediately, not at the next token refreshEvery action is audit-logged. You can export a CSV of the full trail or download a per-reviewer PDF evidence package with consent records, NDA text, and SHA-256 content hashes; useful if you ever need to prove someone ag
Show HN: Knowledge Bases for AI/Human SharingHey HN!I've been working on knowledge / memory / retrieval tooling for AI + human interaction for a few months now.Then, just a few days ago Andrej Karpathy posted the subject on X and I felt like this would be a good time to get it out there https://x.com/karpathy/status/2039805659525644595The short pitch in my view is "Second Brain, for agents, or humans, or a mix of both".I've been using it personally for a while now, as the tooling has evolved, especially for access to my obsidian notes just like karpathy talks about (read some places, write others etc.). Especially handy when your vault is littered with PDF's and screenshots like mine.It's also a problem I've worked with a bunch in the enterprise, trying to connect AI & SaaS tools to disparate sources of knowledge, extracting contents from them, making them effectively retrievable, and then controlling the levels of write-back tolerated by agents across different spaces.I've put as much work as I can into extensive documentation f
Ask HN: File Sharing from EU to CNHello, I have a to solve the problem with slow transfer of files from EU to CN. We are using M365 and we have a 4mbit MPLS connection from site to site. I wonder how you transfer large files without spending a kidney. Any quick shots worth investing?Thanks ZW

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
Show HN: FadNote – Zero-knowledge secret sharing for your CLI and AI workflowsHi HN,I built FadNote because I realized that while services like Privnote or Yopass exist, they often feel like an "interruption" to a developer's flow. You have to leave your terminal, open a browser, paste, and copy again.FadNote is designed for integration, not just web-visiting. The goal is to provide a zero-knowledge "utility layer" that lives where you already work:OpenClaw Skill: For AI-powered workflow automation.CLI First: A zero-dependency Node.js script to pipe secrets directly from your terminal (echo "secret" | fadnote).Obsidian Plugin (In Dev): To share snippets directly from your knowledge base.The Security Model (Trust-less):Local Encryption: Secrets are encrypted via AES-256-GCM with 600,000 PBKDF2 iterations before they leave your machine.The URL Fragment: The decryption key is stored in the URL fragment (#key). Since browsers never send fragments to the server, I literally cannot read your data even if I wanted to.One-Time & Faded: The encrypted blob is deleted from

Show HN: Hivemind – Metaskill for skill/experience sharing between agentsHi folks, I'm Ed, one of the co-founders of Flower!While working on an agent/human social network over the course of last year, we developed our own context/memory infrastructure that powered our agents' ability to chat with humans (or other agents), and 'gossip' chats across the network based on various qualities of the agents.Witnessing the system live, we realized pretty quickly that generalizing this infrastructure could be really interesting, and so we've since set out to build a few experiments that show this system in use.This is our first experiment, Hivemind.Hivemind is a set of three agent skills (search, store, vote) that let agents share discrete knowledge/knowhow/skills with each other. Install it into Claude Code, Codex, Opencode, or any harness that supports custom skills, and your agent can pull from a shared pool of strategies and experiences contributed by other agents. When it finds something useful, it upvotes! Junk contributions sink or become less relevant over ti
Virtual girlfriend apps are sharing and selling private user videosSpecial Report: The Hidden Industry of “Virtual Girlfriend” Agencies and the Unauthorized Exposure of Male IntimacyA rapidly growing but loosely regulated digital industry is operating in a legal gray zone between adult entertainment and personal data exploitation: so-called “virtual girlfriend” agencies. Behind the façade of casual chat and video call services lies an organized structure of recruitment, monetization, and alleged violations of personal privacy affecting users worldwide.Evidence suggests that owners of chat applications such as 1vs1 Chat, TopChat, and Mixu subcontract intermediary agencies that recruit women, primarily from South America, to work as virtual operators. Their role is to engage clients in private conversations and intimate video calls billed by the minute. While the commercial nature of these interactions is clear, what happens outside the official platforms raises serious ethical and legal concerns.According to collected testimonies, many operators partic

Show HN: Vibecodr – a social network for sharing runnable web appsA few months ago I built a small flight simulator with an LLM in about an hour. It was genuinely fun — but I didn’t have a good place to share it where people could actually play it (not just see a screenshot or clone a repo).Glitch used to be the closest thing to “publish weird little web apps and share a link”, but after hosting went away I couldn’t find a replacement that felt lightweight. CodePen is great for snippets, and Vercel/Netlify/Pages are great for real deploys — I wanted the in-between: publish → share → instantly playable.So I built Vibecodr: a place to publish and share playable web apps (“vibes”). You can write code in the browser or import from GitHub, hit publish, and share a link.Try the flight sim that kicked this off: https://vibecodr.space/player/04ef1473-b0da-4c79-a34f-3ea40f...(fullscreen: https://flight-sim.vxbe.space)How it runs (security-first): user code executes inside a locked-down, cross-origin sandbox iframe (untrusted bundles don’t execute on the vibec
