Show HN: MindfulClaude – Guided breathing during Claude Code's thinking time Every time Claude Code thinks, you get 10-60s of idle time, usually spent on context switching or doomscrolling. I turned it into breathing exercises that keep you focused and improve your heart rate variability. Auto-launches a tmux pane using hooks when Claude starts working and disappears when it finishes. https://ift.tt/oFw4hO8 March 9, 2026 at 10:43PM

Show HN: Time as the 4th Dimension – What if it emerges from rotational motion? https://ift.tt/z5iWCLo

Show HN: Time as the 4th Dimension – What if it emerges from rotational motion? I've been developing a framework since 2022 that proposes time is not a static geometric axis (as in Einstein's relativity) but emerges dynamically from the rotational and orbital motion of 3D space. The core idea: each dimension emerges from the previous one by arranging infinite instances perpendicularly. A static 3D space can't do this to itself — but a rotating one can. That perpetual self-perpendicularity is time. From this we can derive the Lorentz factor, E=mc², and the Schwarzschild radius, and propose a testable prediction: intrinsic rotation should contribute independently to time dilation, measurable with atomic clocks.

Show HN: Lobster.js – Extended Markdown with layout blocks and footnotes https://ift.tt/2ExByvQ

Show HN: Lobster.js – Extended Markdown with layout blocks and footnotes Hi HN! I built lobster.js which is an extended Markdown parser that renders directly in the browser — no build tool, no framework, no configuration. The entire setup is a single script tag: It's particularly useful for GitHub Pages sites where you want Markdown-driven content without pulling in Jekyll or Hugo. --- What makes it different from marked.js or markdown-it: Standard parsers convert Markdown to HTML — that's it. lobster.js adds layout primitives to the Markdown syntax itself: - :::warp id defines a named content block; [~id] places it inside a silent table cell. This is how you build multi-column layouts entirely in Markdown, without touching HTML. - :::details Title renders a native

/

collapsible block. - :::header / :::footer define semantic page regions. - Silent tables (~ | ... |) create borderless layout grids. - Cell merging: horizontal (\|) and vertical (\---) spans. - Image sizing: . --- CSS-first design: Every rendered element gets a predictable lbs-* class name (e.g. lbs-heading-1, lbs-table-silent). No default stylesheet is bundled — you bring your own CSS and have full control over appearance. --- The showcase site is itself built with lobster.js. The sidebar is nav.md, and each page is a separate Markdown file loaded dynamically via ?page= query parameters — no JS router, no framework. Markdown is the one format that humans and LLMs both write fluently. If you want a structured static site without a build pipeline, lobster.js lets that Markdown become a full web page — layout and all.

Show HN: VoiceFlow – Sub-second (0.3s-0.6s) voice-to-text built in Rust https://ift.tt/MUk6ZTX

Show HN: VoiceFlow – Sub-second (0.3s-0.6s) voice-to-text built in Rust Hi HN, I was frustrated by the lag in Electron-based Whisper wrappers. Most of them feel disconnected from the typing experience because of the 2-5s delay. I built VoiceFlow to solve this. It’s a native Rust core that targets 0.3s-0.6s latency. The goal is to make voice-to-text feel as instant as typing. Key features: Global hotkey [Ctrl+Space] to type into any app (Slack, VS Code, etc.) Native Rust implementation for performance and low memory footprint AI-based post-processing for punctuation and style Privacy-focused: Microphone is only active during the keypress I'm currently in private beta and looking for feedback, especially on the latency and UX. I'll be around to answer any technical questions! https://ift.tt/Vxthfwz March 8, 2026 at 10:56PM
