Show HN: Site Spy – Track webpage changes with diffs, element picking, and RSS https://ift.tt/W7Fzs3k

Show HN: Site Spy – Track webpage changes with diffs, element picking, and RSS I built Site Spy after missing a visa appointment slot because a government page updated its requirements and I didn't notice for two weeks. It's a browser extension (Chrome + Firefox) and web dashboard that monitors any webpage and shows you exactly what changed — like a git diff for websites. Additions are highlighted in green, removals in red, with a full snapshot timeline to compare any two versions. What makes it different from existing tools: - Element inspector: click any part of a page to track just that element (a price, a stock status, a headline) — skip the noise from ads and timestamps - Snapshot timeline: browse every captured version of a page and compare any two side by side, like git log for websites - RSS feeds: every watch gets its own feed URL, plus feeds per tag and a master feed. Wire it into your reader instead of getting spammed with alerts - MCP server (@site-spy/mcp-server): ...

Show HN: I wrote down every expensive hardware development mistake I've seen https://ift.tt/EC3m7HQ

Show HN: I wrote down every expensive hardware development mistake I've seen I've spent years watching hardware teams make the same mistakes — tooling committed before thermal was resolved, manufacturing processes not validated in PVT that only showed defects at volume, components going EOL unnoticed until the factory tried to order them. The pattern was always the same. The costs were always avoidable. Nobody had written it down. The result is The Hardest Hardware Lessons — covering the full journey from first prototype to end-of-life: EVT/DVT/PVT, factory evaluation, supply chain risk, mass production operations, field failures, and product lifecycle management. https://ift.tt/xvrazuk https://ift.tt/zjgMuV5 March 8, 2026 at 06:29AM

Show HN: AgentSign – Open-source zero trust engine for AI agents https://ift.tt/T8v5iEW

Show HN: AgentSign – Open-source zero trust engine for AI agents Hi HN. This week Meta acquired Moltbook (agent social network), OpenAI acquired Promptfoo (agent testing), and Mandiant's founder raised $190M for Armadin. Agent infrastructure is clearly where things are heading. We built AgentSign -- a zero trust engine for AI agents. The problem: agents are operating without any identity infrastructure. Moltbook went viral for fake posts because there was zero verification on who or what was posting. AgentSign gives every agent a cryptographic identity certificate, signs every action into an execution chain, and runs runtime code attestation before anything executes. There's also an MCP Trust Layer for agent-to-MCP server verification, and a Stripe-powered Trust Gate for agent payments. 5 subsystems: identity certs, execution chain verification, runtime code attestation, output tamper detection, and cryptographic trust scoring. Free and open source. Built in London. SDK: https:...

Show HN: Jottit – Publish in seconds, reviving my 2007 project with Aaron Swartz https://ift.tt/PeXMnau

Show HN: Jottit – Publish in seconds, reviving my 2007 project with Aaron Swartz Aaron Swartz and I built Jottit in 2007 as a really simple way for anyone to make a page on the web in seconds. You just typed something, clicked a button, and you got a page on a secret URL. It went offline years ago. I've now rebuilt it from scratch. It's basically the same idea, but even simpler. Go to jottit.org, write markdown, and you have a published page. Claim it, pick an address, and you now have a feed of your pages at yourname.jottit.org. There's no signup to start writing. And no JS on public pages. You can export your writing when you want. Jottit is free and open source. It's not a startup, just something I really wanted to exist again. https://jottit.org March 11, 2026 at 07:57AM
