Mqtt Broker for 10 Years

Intended for 10-year (plus hopefully) deployment lifetime on $10-30 of silicon. The kind of thing you screw to a wall, plug in, and walk away from for a decade. No telemetry, no phone-home updates, no external dependencies. Storage decisions get a sanity checked against NVS wear... a write-per-PUBLISH would shred the flash in months, so the retained store and in tables that stay in PSRAM. Its heavily written with AI and borrowed a lot of visuals from Tasmota. Not for production use yet (been currently running it for a month with great results!)

In plain words

MQTT Broker for 10 Years is an MQTT broker designed to run on low-cost microcontrollers ($10-30) for decade-long deployments with minimal maintenance. It operates without telemetry, external dependencies, or automatic updates, and manages storage carefully to prevent flash wear by keeping retained messages and tables in PSRAM. Built with AI assistance and inspired by Tasmota's interface, it targets users who need reliable IoT messaging in resource-constrained environments. Currently in early testing stages after a month of successful operation.

    Hey HN, I noticed there are 1,000+ MCP skills on GitHub with zero way for creators to charge for them. So I built Agent37. Selling Claude skills today means asking customers to download your skill, set up Claude Code on their laptops, configure MCP servers, and pray it works. No trial, no updates, often you're just handing over the source. Agent37 lets creators upload a skill, share a link, and anyone can try it instantly (no Claude account needed). Built-in Stripe, creators keep 80%. Looking for feedback on the approach. Would you use something like this?

    We just released an MCP server that lets Claude (or any MCP client) pull real-time and historical financial data: equities, options chains, crypto, FX, commodities, fundamentals, economic indicators, and 50+ technical signals. You can ask things like: “Plot NVDA’s RSI vs AMD’s over the past year.” “Show the yield curve shift since 2020.” “What are Apple’s recent earnings surprise trends? “Make a 3-statement model for ORCL.” Claude runs the requests, does the math, and returns the data or generates charts/models all inside the chat. Setup takes about a minute. You’ll need Claude Pro…

  • Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!
