Show HN: Help SourceLibrary.org Translate the Renaissance

SourceLibrary.org is currently the world’s largest online library of translated ancient sources. It contains over 15,000 books translated from dozens of languages (Latin, Greek, Chinese, Sanskrit, Arabic, Hebrew, Egyptian, etc)—from sacred texts to early science. Our vision is to make ancient wisdom accessible to both people and AI.Did you know that less than 3% of the Latin Renaissance has ever been translated into English?This is ironic, because translations of ancient Greek wisdom texts are h

Ask HN: I made an image watermarking tool. What are the issues open-sourcing it?

A couple months ago, I found that a) visual image watermarking is trivially defeated by AI image editing so invisible image watermarks are likely the future and b) the only steganographic image watermarking tools are hard-to-use open-source tools or proprietary tools like SynthID. So as an experiment I tried using agents to create a novel image watermarking approach…and it unexpectedly worked: mostly imperceptible, tamper resistant, higher capacity, doesn't use a neural network, and real ti

Show HN: Nightwatch, The open-source, read-only AI SRE

nightwatch is a local-first, read-only layer on top of your monitoring. it groups alert storm into incidents, flags noisy checks and has an agent that can investigate for you live systems. You can e.g. jump from the incident into the agent directly.the reason for this weekend project is that we had a kubernetes upgrade that went wrong, and at some point a rollback wasn't possible anymore, so it had to be fixed live during the night while several problems came together. We run a lot of diffe

Show HN: Web Speed – A shared web-map registry for AI agents (MCP, open source)

Hey everyone, I've been working on a tool called Web Speed. It takes web pages full of HTML and parses them into an easily readable sitemap for an AI agent. By ensuring the AI doesn't have to analyze the full HTML from the page or screenshots of the page, it makes the agent a lot cheaper and faster. It's MCP-native, so any AI that supports MCP can run it and take control of your browser for you. There are both “normal” and post-auth versions live on GitHub. What I think is the coo

Securing CI/CD for an open source project: Controlling who runs what

Part oneThe last twelve months have been rough on the open source supply chain. Axios was compromised on npm and shipped a remote access trojan inside otherwise normal-looking releases. LiteLLM’s PyPI package was hijacked to exfiltrate environment variables. Typosquatted forks of Trivy were published to catch people who fat-finger go install. And the canonical example, the 2020 SolarWinds breach, is still the cautionary tale we keep coming back to: attackers got into the build system and p

Journey to JPEG XL: How open source experiments shaped the future of image coding

by Jyrki Alakuijala, Zoltán Szabadka & Luca Versari, Paradigms of Intelligence, Google Technology & SocietyBuilding the Next Generation Image StandardThe internet runs on images. Since the early days of the web, there has been a relentless tension between visual fidelity and bandwidth. For decades, the industry relied on the venerable JPEG standard for images loading fast. It served us remarkably well, but as displays moved to High Dynamic Range (HDR) and Wide Color Gamut (WCG), the form
