tldx

What it does

Finding a good domain is half the battle. tldx is a blazing-fast, concurrent CLI tool that generates and checks domain availability in bulk via RDAP. Mix keywords, prefixes/suffixes, or regex, and stream results to stdout, JSON, or CSV. Plus, tldx includes an MCP server, empowering AI agents (like Claude) to brainstorm and verify domains for you automatically! Install via Homebrew (brew install tldx). Say goodbye to rate-limits and legacy whois parsing. 100% Free & Open Source in Go.

Bulk domain availability checking via RDAP, DNS, and WHOIS, with prefix/suffix permutations, regex patterns, MCP, and multiple output formats - brandonyoungdev/tldx

  Talanoa▲340

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  Needle: We Distilled Gemini Tool Calling into a 26M Model▲776

  Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
