Bitchat – A decentralized messaging app that works over Bluetooth mesh networks

<a href="https:&#x2F;&#x2F;lisagui.com&#x2F;info.html" rel="nofollow">https:&#x2F;&#x2F;lisagui.com&#x2F;info.html</a>This is a web OS I wrote in vanilla JS that looks like the Apple Lisa Office System (1983-85), with other contemporaneous influences and additional improvements and features. It&#x27;s currently in alpha and isn&#x27;t remotely bug free. I had been holding off on posting this here until it was somewhat presentable and useful. Please note; the Lisa conforms more literally to the desktop metaphor than most modern GUIs - some of the important differences are mentioned in the readme.This is a complete recreation of the UI in JS; it all renders to a single canvas element. It&#x27;s not a CSS theme, and not an emulator ported to JS. None of the code is written by Apple. I&#x27;ll be happy to elaborate more in the comments, but the short version is the entire UI is defined outside the DOM using JS objects. Thus, every interface element - menus, windows, controls, and even typefaces - was recreated from scratch. There are no font files - I wrote my own typesetting system, which supports combining multiple text styles and generates new glyph variants on the fly.Many of the technical decisions I made were motivated by a desire to have this look the same in every browser. That&#x27;s harder to do with the DOM and CSS, and why I moved as much logic as I could to JS. Also, the only part of the project outside of vanilla JS and standard web APIs is the Gulp toolkit, which I&#x27;m using as a minification&#x2F;build tool. No vibe coding was used to make this!This is based on a UI from the 80s, and won&#x27;t work well on your phone. If you insist on running it that way, turn on trackpad mode in the touchscreen settings panel of the preferences app. For best results, install it as a PWA (add it to your home screen). Also there are some odd Android bugs; the native touchscreen keyboard is currently broken, and there&#x27;s an issue with the cursor when dragging windows.I realize there&#x27;s not a whole lot to do within LisaGUI right now; I&#x27;ve got a big list of additional features and apps I&#x27;ll be adding in the future. I&#x27;ve been working on this project for a while, and I&#x27;m eager to hear people&#x27;s feedback and answer questions about it.

Hello HN!As a long term NYC resident, I have read countless articles on ideas tweaking subway services, but always found them hard to follow without visual aid. So over the long weekend I decided to build one. It has all the basic features: trains would spawn at their origin, stop at stations, and slow down if it gets too close to another. You can also design custom routes by piecing tracks together.Have fun, and let me know what you think!

Hey HN, I’m Tejas at Morph. We’ve built a blazing-fast model for applying AI-generated code edits directly into your files at 4,500+ tokens&#x2F;sec. No more slow full-file rewrites or brittle search-and-replace hacks.Why? AI spits out code that can’t reliably be inserted into existing code. Full file rewrites, brittle search-and-replace hacks are too slow, expensive, or error-prone.Morph&#x27;s approach:- Your agent outputs edits “lazily”, referencing unmodified lines in the existing file (ex: &#x2F;&#x2F; ...existing code...)- Morph instantly applies these edits to a file using our Fast Apply model + speculative decoding against the original file, making AI patches fast, reliable, and production-ready.This approach was pioneered by Cursor last year, but their models aren’t available as APIs—so we built Morph for developers everywhere (with a large free tier!)Live demo (no signup): <a href="https:&#x2F;&#x2F;morphllm.com&#x2F;dashboard">https:&#x2F;&#x2F;morphllm.com&#x2F;dashboard</a> and docs: <a href="https:&#x2F;&#x2F;docs.morphllm.com&#x2F;quickstart">https:&#x2F;&#x2F;docs.morphllm.com&#x2F;quickstart</a>We have 2 Fast Apply models: morph-v3-fast - 4500+ tok&#x2F;sec, and morph-v3-large - 2500+ tok&#x2F;sec. These models power Fast Apply at create.xyz, databutton, continue.dev, and more!We also provide retrieval models for embedding + reranking.
Next Up: Inline Edit Model (Cmd-K): Extremely fast inline edits - keep dev flow state; and Morph Tab API: Our Next Edit Prediction model guesses your next code edit + action with sub-500ms latency. It&#x27;s currently in private beta, but you can request early access here: <a href="https:&#x2F;&#x2F;morphllm.com&#x2F;tab">https:&#x2F;&#x2F;morphllm.com&#x2F;tab</a>Hot takes:1) Raw inference speed matters more than incremental accuracy gains for dev UX—agree or disagree?2) Full-file rewrites by frontier models are legacy—Fast Apply edits win on speed, cost, reliability.3) As benchmarks on narrow tasks saturate to 99%+, complexity is shifting from single frontier models to specialized inference-optimized models. As frontier models move upmarket, they&#x27;ll leave simple tasks behind, and they&#x27;ll be used to do tasks only frontier models can doWe’d love to hear your ideas and experiences with coding agents!<a href="https:&#x2F;&#x2F;youtu.be&#x2F;LdT8epGHJPk" rel="nofollow">https:&#x2F;&#x2F;youtu.be&#x2F;LdT8epGHJPk</a>
