Show HN: The Unix Magic poster, annotated (updated) https://bit.ly/4tyhTHD

Show HN: The Unix Magic poster, annotated (updated) This is a site that maps the references on Gary Overacre's 1980s UNIX Magic poster to short write-ups with sources. I posted an earlier version about a year ago [1]. Since then I rewrote some of the annotations, added deep-linking to individual markers and a frame/sidebar view, gave the site a terminal-style redesign, and fixed historical inaccuracies (daemon etymology, nroff origin, B language vs. Multics, etc.). Contributions and comments welcome; each marker is a GitHub issue. site: https://bit.ly/4t3NxMh [1] https://bit.ly/4hUhSaK https://bit.ly/3EzK3xr April 27, 2026 at 02:32AM

Show HN: VT Code – Rust TUI coding agent with multi-provider support https://bit.ly/4u8nJiS

Show HN: VT Code – Rust TUI coding agent with multi-provider support Hi HN, I built VT Code, a semantic coding agent. Supports all SOTA and open sources model. Anthropic, OpenAI, Gemini, Codex. Agent Skills, Model Context Protocol and Agent Client Protocol (ACP) ready. All open source models are support. Local inference via LM Studio and Ollama (experiment). Semantic context understanding is supported by ast-grep for structured code search and ripgrep for powered grep. I built VT Code in Rust on Ratatui. Architecture and agent loop documented in the README and DeepWiki. Repo: https://bit.ly/4sTIE8i DeepWiki: https://bit.ly/4cxi14r Happy to answer questions! I believe coding harnesses should be open, and everyone should have a choice of their preferred way to work in this agentic engineering era. https://bit.ly/4sTIE8i April 25, 2026 at 04:17AM

Show HN: RoboAPI – A unified REST API for robots, like Stripe but for hardware https://bit.ly/3Qv1DbY

Show HN: RoboAPI – A unified REST API for robots, like Stripe but for hardware Every robot manufacturer ships a different SDK and a different protocol. A Boston Dynamics Spot speaks nothing like a Universal Robots arm. Every team building on top of robots rewrites the same integration layer from scratch. This is a massive tax on the industry. RoboAPI is a unified API layer that abstracts all of that into one clean developer experience. One SDK, one API key, any robot — simulated or real hardware. You can connect a simulated robot and read live telemetry in under 5 minutes: pip install fastapi uvicorn roslibpy uvicorn api.main:app --reload curl -X POST localhost:8000/v1/robots/connect -d '{"robot_id":"bot-01","brand":"simulated"}' curl localhost:8000/v1/robots/bot-01/sense It also connects to real ROS2 robots via rosbridge — I tested it today controlling a turtlesim robot drawing circles through the API. The architecture is pluggable — each robot brand is a separate adapter implementing a common interface (like a payment gateway in Stripe). Adding a new brand means one file. Currently supports: simulated robots and any ROS2 robot. Boston Dynamics and Universal Robots adapters are next. Would love feedback from anyone working in robotics — especially on the API design and what's missing for real-world use. https://bit.ly/3QyRJWM April 25, 2026 at 12:16AM

Show HN: Nimbus – Browser with Claude Code UX https://bit.ly/41XYTX5

Show HN: Nimbus – Browser with Claude Code UX Hi HN, I'm Anil. Nimbus is a desktop browser with an AI agent built into it. The UX is shamelessly inspired by Claude Code: a chat bar at the bottom, an agent log above it, and the webpage itself when its needed. This is mainly a UX experiment for me. And also the reason it isn't a Chrome extension: once you have a chat bar that understands intent, the URL field is redundant. You shouldn't have two places to tell the browser what you want. I didn't want to bolt an agent onto an existing browser's chrome and end up with duplicated controls everywhere — I wanted full freedom to redesign the shell from scratch, decide what stays, what goes, and what a browser even looks like when the agent is the primary interface.

Show HN: I built a toy that plays grandma's stories when my daughter hugs it https://bit.ly/4d3RGLe

Show HN: I built a toy that plays grandma's stories when my daughter hugs it This was a project I built for my daughter's first birthday present. For context, I'm a surgical resident in the UK by background and am currently taking a year out of training to study a masters in computer science. My daughter just turned one. There are two things she really loves: the first is particular soft toy that she just can't live without, and the other is a good story book. Her grandparents live hours away and I didn't want her to forget what they sound like between visits. I wanted her to hear them whenever she missed them. My parents brought my brother and I up with incredible stories and books from all sorts of cultures, many of the stories being passed down from their parents before them. I didn't want my daughter to miss out on that. Finally, I was sick of missing storytime with her when I had to leave for night shifts. I wanted her to hear my voice before she slept every night. For all these reasons, I decided to build Storyfriend. It's her favourite soft toy with a custom made speaker-module inside. I combined my surgical skills with the skills I was learning as a CS student. Along the way I dipped my toes into the world of 3D printing, CAD and electronics design. When she hugs the toy, it plays stories read by her grandparents. She can take the toy with her anywhere and hear the stories anytime she wants - it works offline and has internal storage. It meets my wife's strict no-screen rule (which is getting harder to stick to as the days go by). I've recorded some of the stories that we would read together, so that on nights when I'm working she still has me there to read her a bedtime story. The bit I'm most pleased with: grandparents don't need an app. They just call a phone number. The audio routes through my server and pushes to the toy over WiFi. My own 86-year old grandmother in a rural village in another country can do it by just making a regular call via her landline, as she has done for many years - no help needed, no apps required, no smartphones involved. Hardware is a BLE/wifi module with a MAX98357 chip and custome battery management system, all soldered together, placed in a 3D printed enclosure and placed into a compartment that I stitched into her cuddly toy. Firmware pulls new messages when connected to WiFi and stores them on an SD card. So far I've sold a few hand-made units to parents and grandparents who resonated with the project. Site: https://bit.ly/4w3BEsy Would love feedback on the technical approach, the product itself, or anything else. Happy to answer questions about the build https://bit.ly/4u18OHd April 24, 2026 at 01:06AM
