Ask HN: Gmail spam filtering suddenly marking everything as spam?

Almost all transactional emails are being marked as suspicious even when their SPF/DKIM records are fine and they’ve been whitelisted before. Did Google break something in gmail/spam filtering?

Show HN: Teemux – Zero-config log multiplexer with built-in MCP server
4 by gajus | 0 comments on Hacker News.
I started to use AI agents for coding and quickly ran into a frustrating limitation – there is no easy way to share my development environment logs with AI agents. So that's what is Teemux. A simple CLI program that aggregates logs, makes them available to you as a developer (in a pretty UI), and makes them available to your AI coding agents using MCP. There is one implementation detail that I geek out about: It is zero config and has built-in leader nomination for running the web server and MCP server. When you start one `teemux` instance, it starts web server, .. when you start second and third instances, they join the first server and start merging logs. If you were to kill the first instance, a new leader is nominated. This design allows to seamless add/remove nodes that share logs (a process that historically would have taken a central log aggregator). A super quick demo: npx teemux -- curl -N https://ift.tt/WkSsVga

Show HN: Synesthesia, make noise music with a colorpicker
6 by tevans3 | 2 comments on Hacker News.
This is a (silly, little) app which lets you make noise music using a color picker as an instrument. When you click on a specific point in the color picker, a bit of JavaScript maps the binary representation of the clicked-on color's hex-code to a "chord" in the 24 tone-equal-temperament scale. That chord is then played back using a throttled audio generation method which was implemented via Tone.js. NOTE! Turn the volume way down before using the site. It is noise music. :)

Show HN: Bible translated using LLMs from source Greek and Hebrew

Built an auditable AI (Bible) translation pipeline: Hebrew/Greek source packets -> verse JSON with notes rolling up to chapters, books, and testaments. Final texts compiled with metrics (TTR, n-grams). This is the first full-text example as far as I know (Gen Z bible doesn't count). There are hallucinations and issues, but the overall quality surprised me. LLMs have a lot of promise translating and rendering 'accessible' more ancient texts. The technology has a lot of benefit for the faithful, that I think is only beginning to be explored.

New top story on Hacker News: Show HN: ContextFort – Visibility and controls for browser agents
Show HN: ContextFort – Visibility and controls for browser agents
8 by ashwinr2002 | 1 comments on Hacker News.
Hey HN! I’m Ashwin, co-founder of ContextFort ( https://contextfort.ai/ ). We provide visibility and controls for AI browser agents like Claude in Chrome through an open-source browser extension. Browser agents are AI copilots that can autonomously navigate and take actions in your browser. They show up as standalone browsers (Comet, Atlas) or Chrome extensions (Claude). They’re especially useful in sites where search/API connectors don’t work well, like searching through Google Groups threads for a bug fix or pulling invoices from BILL.com. Anthropic released Claude CoWork yesterday, and in their launch video, they showcased their browser-use chromium extension: https://www.youtube.com/watch?v=UAmKyyZ-b9E But enterprise adoption is slow because of indirect prompt injection risks, about which Simon Willison has written in great detail in his blogs: https://ift.tt/3Mg8dtE... . And before security teams can decide on guardrails, they need to know how employees are using browser agents to understand where the risks are. So, we reverse-engineered how the Claude in Chrome extension works and built a visibility layer that tracks agent sessions end-to-end. It detects when an AI agent takes control of the browser and records which pages it visited during a session and what it does on each page (what was clicked and where text was input). On top of that, we’ve also added simple controls for security teams to act on based on what the visibility layer captures: (1) Block specific actions on specific pages (e.g., prevent the agent from clicking “Submit” on email) (2) Block risky cross-site flows in a single session (e.g., block navigation to Atlassian after interacting with StackOverflow), or apply a stricter policy and block bringing any external context to Atlassian entirely. We demo all the above features here in this 2-minute YouTube video: https://www.youtube.com/watch?v=1YtEGVZKMeo You can try our browser extension here: https://ift.tt/R5whPbZ Thrilled to share this with you and hear your comments!

Unauthenticated remote code execution in OpenCode

Previous versions of OpenCode started a server which allowed any website visited in a web browser to execute arbitrary commands on the local machine. Make sure you are using v1.1.10 or newer; see link for more details.

Show HN: Hover – IDE style hover documentation on any webpage
5 by sampsonj | 0 comments on Hacker News.
I thought it would be interesting to have ID style hover docs outside the IDE. Hover is a Chrome extension that gives you IDE style hover tooltips on any webpage: documentation sites, ChatGPT, Claude, etc. How it works: - When a code block comes into view, the extension detects tokens and sends the code to an LLM (via OpenRouter or custom endpoint) - The LLM generates documentation for tokens worth documenting, which gets cached - On hover, the cached documentation is displayed instantly A few things I wanted to get right: - Website permissions are granular and use Chrome's permission system, so the extension only runs where you allow it - Custom endpoints let you skip OpenRouter entirely – if you're at a company with its own infra, you can point it at AWS Bedrock, Google AI Studio, or whatever you have Built with TypeScript, Vite, and the Chrome extension APIs. Coming to the Chrome Web Store soon. Would love feedback on the onboarding experience and general UX – there were a lot of design decisions I wasn't sure about. Happy to answer questions about the implementation.

Show HN: Feature detection exploration in Lidar DEMs via differential decomp
3 by DarkForestery | 0 comments on Hacker News.
I'm not a geospatial expert — I work in AI/ML. This started when I was exploring LiDAR data with agentic assitince and noticed that different signal decomposition methods revealed different terrain features. The core idea: if you systematically combine decomposition methods (Gaussian, bilateral, wavelet, morphological, etc.) with different upsampling techniques, each combination has characteristic "failure modes" that selectively preserve or eliminate certain features. The differences between outputs become feature-specific filters. The framework tests 25 decomposition × 19 upsampling methods across parameter ranges — about 40,000 combinations total. The visualization grid makes it easy to compare which methods work for what. Built in Cursor with Opus 4.5, NumPy, SciPy, scikit-image, PyWavelets, and OpenCV. Apache 2.0 licensed. I'd appreciate feedback from anyone who actually works with elevation data. What am I missing? What's obvious to practitioners that I wouldn't know?
