Claude64, a Commodore 64 client for Claude

What it does

Type a message on the C64, get a streaming response from Claude — over a real (emulated) RS-232 serial connection.

The proxy handles IP232 framing, conversation history, and streaming the Anthropic Messages API back to the C64 one character at a time. make Produces c64/build/claude64.prg and copies the Swiftlink driver to c64/build/c64-swlink.ser . export ANTHROPIC_API_KEY=sk-ant-... ./scripts/run.sh This starts the proxy and…from github.com

  Hi HN, We use Claude Code a lot, and after a long session there isn't a simple way to share exactly what happened with someone else. Prompts, responses, file edits, and tool calls all stay inside the terminal. We built Claudebin to make that easier. It's a plugin that lets you export the current session as a URL containing: - the full message thread - file reads and writes - bash commands - web and MCP calls You can send the link to someone, attach it to a PR, embed part of it, or resume the session locally. It's open source. GitHub:…

  Claudraband – Claude Code for the Power UserApr 2026 · github.com · ▲120

  Hello everyone. Claudraband wraps a Claude Code TUI in a controlled terminal to enable extended workflows. It uses tmux for visible controlled sessions or xterm.js for headless sessions (a little slower), but everything is mediated by an actual Claude Code TUI. One example of a workflow I use now is having my current Claude Code interrogate older sessions for certain decisions it made: https://github.com/halfwhey/claudraband?tab=readme-ov-file#s... This project provides: - Resumable non-interactive workflows. Essentially `claude -p` with session support: `cband continue…

  Talanoa▲346

  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…
