Show HN: A native Hacker News reader with integrated todo/done tracking https://ift.tt/gAldXKD

Show HN: A native Hacker News reader with integrated todo/done tracking Hey HN! I'm excited to share a tool I've been working on - a native Hacker News reader built with Rust and egui. Here's a screenshot: https://ift.tt/TXCQpDk... . As a daily HN reader, I've always struggled with keeping track of interesting posts I want to read later. Browser tabs pile up, bookmarks get forgotten, and I lose track of what I've already read. I needed a way to: 1. Browse HN efficiently (across all sections - hot, new, show, ask, jobs, best) 2. Quickly mark posts as "todo" for later reading 3. Mark posts as "done" when finished 4. Filter and search effectively I couldn't find a tool that combined all these features, so I built one. It's been tremendously helpful for my own HN reading workflow, and I thought others might find it useful too. Features: - *Integrated todo tracking*: Mark stories as "todo" and "done" to manage your reading progress - *Search functionality*: Filter stories by keyword in title, domain, or author - *Multiple sections*: Browse all HN sections (hot, new, show, ask, jobs, best) - *Threaded comments*: View comments in a Reddit-like threaded format - *Dark/light mode*: Easy on the eyes in any environment - *Keyboard shortcuts*: Efficient navigation with keyboard-centric design (1-6 for tabs, Ctrl+F for search) - *Auto-loading*: Automatically loads more content when scrolling - *Color-coding*: Stories color-coded by score for easy scanning - *Native app*: Fast, responsive, and works offline with local caching Built with Rust and the egui UI framework, with SQLite for local storage. The app scrapes Hacker News HTML directly rather than using the official API to capture the full story context. Check out the GitHub repo ( https://ift.tt/vP76tIc ) for installation instructions and source code. Built and tested on macOS, Linux, and Windows. This started as a personal tool to solve my own HN reading habits, but I hope others find it useful too. The code is MIT licensed and I'd love your feedback, feature suggestions, or contributions! https://ift.tt/VbSTW1M May 19, 2025 at 11:53PM

Show HN: Python Simulator of David Deutsch’s "Constructor Theory of Time" https://ift.tt/ne0WopU

Show HN: Python Simulator of David Deutsch’s "Constructor Theory of Time" Hi HN, I turned the freshly published paper “The Constructor Theory of Time” by David Deutsch and Chiara Marletto (arXiv, 13 May 2025) into an executable Python library. What you’ll find • One-to-one translation of the paper’s formalism: Substrates, Attributes, Tasks, Constructors, and task-algebra operators • Possibility / impossibility predicates and counterfactuals encoded exactly as defined • Test suite that mirrors every lemma and example (>95 % coverage, mypy-typed) • Reproductions of key results: time-keeping substrates, irreversibility proofs, quantum branching tasks, and a self-replicating constructor Why share? Reading the paper is tough going; expressing each definition in code clarified the ideas and surfaced a couple of questions for discussion. Hoping it helps others and sparks extensions. Looking for feedback: • Did I miss any subtleties in the formalism? • Which additional theorems or examples would you like implemented next? Repo: https://ift.tt/s0YNpMn Thanks for taking a look—issues and PRs welcome! https://ift.tt/s0YNpMn May 19, 2025 at 01:52AM

Show HN: Stack Error – ergonomic error handling for Rust https://ift.tt/8wxHSzf

Show HN: Stack Error – ergonomic error handling for Rust Stack Error reduces the up-front cost of designing an error handling solution for your project, so that you focus on writing great libraries and applications. Stack Error has three goals: 1. Provide ergonomics similar to anyhow. 2. Create informative error messages that facilitate debugging. 3. Provide typed data that facilitates runtime error handling. https://ift.tt/TxYtcZz May 19, 2025 at 12:16AM
