I'm working on a own x86_64 UEFI Operating System (OS). The idea is to make an OS that looks like Windows Vista but behave like Linux, so it's a mix of Windows and Linux. I've startet three weeks ago with a custom bootloader and the legacy bios VGA textbuffer and now I'm working on a real USB-HID (USB-Human Interface Device) and have troubles with the keyboard. I also have problems with booting from real hardware. If anyone is good at low level developing the project is source available and I appreciate collaborations with other os developers. Link to Codeberg-repo: https://codeberg.org/vntx-labs/VeloOSHope that is no problem that I use this thread a bit for self-promotion. If so just write a reply I'll remove this comment if this is a problemreplymkdcrl 0 minutes ago | prev | next [–]
Cricket, a visual scripting plugin for Figma inspired by Grasshopper for Rhino.I find Grasshopper, especially its data model, ideal for a certain type of algorithmic art/design, and have always wanted to use it in a 2D graphics package.https://www.figma.com/community/plugin/1677548868352947603/c...replyvmsp 3 minutes ago | prev | next [–]
I've been building a framework for web, ios and android native development at https://github.com/vmsp/flypath.It's based on the Server-Driven UI philosophy where the backend streams both code and UI into a frontend that just knows how to render what it's told. This is pretty cool because it makes it makes over-the-air updates possible.It also follows the batteries-included philosophy of Rails. Has an ORM, background and cron jobs (all based on Postgres), Django-style migrations, JSX Emails and pretty great FFI that's built around a simple `"use native"` directive, in the React Server Component fashion).replymickeyvanolst 3 minutes ago | prev | next [–]
I've been working on a collection of native AI/ML operators for TouchDesigner on macOS. Think of it as a happy marriage between the interface of TouchDesigner but with some of the features you know from ComfyUI.https://www.patreon.com/MickeyvanOlst/posts/meet-aml-macos-1...Typically TD for the Mac has always been a bit underserved, by leaning into some of the frameworks that exclusively exist on macOS I'm hoping more people will see it as a viable platform for this kind of stuff.replyprimaprashant 4 minutes ago | prev | next [–]
Haven't added a demo to the repo yet (will do soon) but building this TUI [1] in Go to manage my agent skills.I don't like putting 20-30 agent skills in the .claude/skills/ dir and letting the agent figure it out. I keep all the skills I've created and adapted over time in a separate git repo and then from there I copy them to the project skill dir when i need them for a session and then remove them when I'm done.This TUI just replaces all the manual work with ls, cp -r, and rm -rf commands with a few keystrokes.[1] https://github.com/primaprashant/seireplyponyous 8 minutes ago | prev | next [–]
https://grandpacad.com - AI modeling for 3D printing
Been at it for about year and a half.Really exciting stuff is happening literally every month, because underlying models are getting better and better. When I started it was pretty basic: “make a cube with a hole through it”. Now it’s at the point “make a raspberry pi 4 case” and the agent searches, builds, verifies…What surprised me in this process is how little meaning AI benchmarks have. Pareto frontier for my use case looks completely different than any other benchmark portrays.replyspottedmarley 16 minutes ago | prev | next [–]

I’ve been hacking on a single Anki extension for… the last three years now:https://smart-notes.xyzThe idea is to make an extension that allows you to flexibly fill out fields on your cards with AI generated text, speech, and images. Think generating example sentences for your entire deck, or adding furigana to kanji (small phonetic characters with a very delicate syntax). It works just as well for language learners as it does for medical students, etc.The secondary goal has been to make this the most well designed, intuitive, and stable Anki extension in the world. I don’t think it’s there yet, but it’s on its way. It’s been very interesting to try to work out a design that affords the flexibility to generate anything for whatever you’re studying but remains approachable and discoverable to your marginal Anki user, many of whom are younger and have varying levels of English ability. Many interesting technical challenges as well.Slowly building towards the Show HN post, but need a few more features. Connecting with and chatting with dedicated users in countries around the world over the last few years has made this the most gratifying thing I’ve ever built! It’s still at the scale that receiving support emails is fun and I can build relationships with power users and long term subscribers.replyle-flaneur 5 minutes ago | prev | next [–]
Slowly putting my photography online again at https://flaneurphoto.com - in the middle of composing soundscapes for some of the works.Finally getting around to organising my photo archive and setting up a metadata extraction pipeline that makes sense for me.(At the day job, curious about adapting app layouts to accommodate the iPhone Duo and address the various Android foldables at the same time, too).replyhombre_fatal 12 minutes ago | prev | next [–]
- danterm (https://github.com/danneu/danterm): a better terminal than iterm, ghostty, kitty, etc.- braid (https://github.com/danneu/braid): a luks+btrfs tool for managing an encrypted disk pool on my NixOS NAS.- tes3-es (https://github.com/danneu/tes3-es): a comprehensive latam translation of Morrowind.I really like Morrowind's data file format -- how it's just a sequence of records -- except how bad it is for localization.Basically, you provide a key for quest/info dialogue like "the ruins", and any time "the ruins" appears in dialogue, the text is hyperlinked such that if you click it, it activates the target dialogue.But this implicit behavior means that even the production game has a lot of accidental hyperlinks and some bugs like orphaned dialogue branches because someone changed the text to "those ruins" not realizing "the ruins" was critical.So I used a bunch of LLMs to build a glossary system and lint tools to check consistency. Ideally OpenMW would implement some QoLs here like a l10n dictionary system + markup like "I heard about {the ruins|1823432}."As usual, my sideproject throughput is entirely limited by tokens.replyitake 3 minutes ago | prev | next [–]

I'm decompiling an obscure 1998 computer game using an LLM agent skill that I'm simultaneously developing from papers and books on reverse-engineering (a subject I've never previously engaged with) with the aim of migrating it (well, at least its assets) to the browser: https://esoteria.pages.devHere's the skill: https://github.com/gavmor/x86-cpp-reversing-skillIt's all slop, but it's battle-tested and producing results. It's quite fun and inspiring to see some of these assets like textures and geometry that are improperly decompiled, bit shifted or something like that. produces a lot of abstract, glitchy art.To make sure that my process and results are reproducible, I've gotten back into maintaining Concourse CI pipelines. They were very useful when we were shipping a fork of k8s for VMware, and now they are a fun way of shipping cyberpunk billboard sprites to Cloudflare buckets.I got back into Concourse in order to attempt a more rigorous approach to generative AI experimentation as well. Unfortunately, there are just so many odd techniques, configurations, loras, and utilities striking my fancy that my experiment pipelines have exploded into the dozens, and Concourse is not a large enough or a high-level enough organizing principle.replylapkaaaa 10 minutes ago | prev | next [–]

I’m building a website for discovering first names that’s enjoyable to explore: https://abracadanames.comIt started with a family member telling me they were frustrated with existing websites. What I noticed is that in many cases they feel cluttered and not smooth to use, almost like a 1-to-1 translation of the underlying database queries, where they have you choose filters and sorting options upfront then browse the paginated results.I wanted to avoid all of that by creating a different experience; I built an interactive full-screen wall UI with infinite browsing so that most of the screen space is dedicated to the core content. I worked on the name sampling algorithm to try to make it as enjoyable to browse as I could, and the only filter displayed by default is the one to select genders.More advanced queries are available through the search field which supports natural language queries, running on a local multilingual interpretation engine with a cloud LLM fallback. The database engine is custom built with Rust, compiled to WASM for higher performance when running on CloudFlare Workers. I don’t use an external DB service for names today.What I’m pretty proud of is to know a lot of technical work is hidden behind that UI, and how it has been shaped by the experience I wanted instead of the other way around.replyMomohNobert 29 minutes ago | parent | next [–]

I've continued working on my game project, Vestiges, which is a 2D narrative strategy rogue-like in Godot. In brief: I once had a career in game development, in game design or project direction roles. Life circumstances derailed my career some years ago, but earlier this year a colleague encouraged me to experiment with genAI. I began Vestiges to see if I could create something again, to enjoy the creative process. It progressed well enough that I'm planning to complete and release it.For various reasons unrelated to the project, progress since last month has been slow (and I expect the next month will be as well). Most of the work I've done has been for peripheral features, not anything on the critical path. After my brother bounced off of the narrative elements (not unexpected :) ), I added an "aliterate" lens that distills the game into its strategy gameplay, burying the narrative content for those who aren't interested in it.In preparation for releasing a demo version, I added opt-in collection of a session's gameplay data, which I intend to analyze to find ways to improve the UI, UX, gameplay, balance. By default, no identifying information whatsoever is collected. A separate opt-in adds minimal technical information (things like OS, CPU, GPU, display settings).I added global text size option as an accessibility feature and used an MCP server to have Claude do the initial layout testing. This was an interesting experiment, but requires enough tokens that it's not very practical as a frequent part of development. These features went hand-in-hand -- via the MCP server, Claude takes a screenshot every five seconds to decide what to hover over or click on next. These screenshots consume tokens rapidly, so they are reduced in size. With a larger font size, the screenshots can be reduced further with the text remaining legible to Claude.Other housekeeping: numerous iterative improvements to my general development process and use of Claude. I wrote my first simple skill: used in conjunction with the brainstorming skill from the superpowers plugin, Claude creates an "origin" document that preserves my initial prompt and some aspects of the brainstorming discussion.I expect to launch a demo version once my current life situation settles a bit. I'm still not in any particular hurry, but it would be good to start getting player feedback. Also, to the whatever extent I do want Vestiges to have any commercial success, the largest obstacle I'll face is discoverability and marketing.A meta-comment: When I first mentioned this project, in the July "What are you working on?" (https://news.ycombinator.com/item?id=48886151), I explained some back story of this project. It got a fair amount of attention, rising to the top of the post and encouraging some discussion. Last month (https://news.ycombinator.com/item?id=49234405), I didn't repeat my story and received no upvotes or comments. This presents me with a quandary because it feels uncomfortable/self-indulgent to repeat my story each time, yet without that context, my project isn't particularly notable or interesting. (Or maybe luck/timing was a factor?)reply

A collection of ongoing projects presented in this discussion spans operating system development, novel web and mobile frameworks, artificial intelligence applications, specialized media tools, and innovative user interface design. One contributor is developing a custom x86_64 UEFI Operating System, attempting to blend the appearance of Windows Vista with the behavior of Linux, facing challenges in low-level hardware interaction such as USB-HID and booting from physical hardware. Another is constructing a comprehensive framework, flypath, designed for native development across web, iOS, and Android, predicated on a Server-Driven UI philosophy that supports features like an object-relational mapper, background job management, and a Foreign Function Interface based on a simple native directive.

In the realm of creative tools and design, there is work on visual scripting plugins like Cricket for Figma, which draws inspiration from Grasshopper for Rhino's data model to facilitate algorithmic art and design in two dimensions. Furthermore, applications are being developed to interface AI/ML with creative software, such as a collection of native AI/ML operators for TouchDesigner on macOS, aiming to unify the interface with functionalities found in systems like ComfyUI. On the generative AI side, one project involves using LLM agents for reverse-engineering obscure computer games, combining this with research on reverse-engineering to migrate assets to the browser, which has generated abstract artistic results. There is also an interest in applying AI to complex modeling tasks, such as developing AI for 3D printing, where the focus is on agent-driven processes, though the scarcity of established benchmarks in this area is noted.

Utility and infrastructure projects are also prominent. A specialized media tagging library, TagLib-Wasm, has been created to implement tagging functionality in JavaScript and TypeScript, intended to function similarly to Mutagen, while operating across various environments including browsers and Cloudflare Workers. Other infrastructure work includes a custom tool site for discovering first names, which employs a full-screen wall user interface and custom database systems built in Rust compiled to WebAssembly for performance, incorporating natural language search with a large language model fallback. A different approach involves building a Tool site that aggregates various essential tools incrementally.

In the domain of agent-based development and systems management, there are efforts to create a tool user interface manager built in Go for agent skills, designed to streamline the management of skills using concise commands. Another effort involves building a world news system, pronto.stream, experimenting with communication formats more efficient than JSON for agent interaction, and exploring the capabilities of a centralized control plane to manage and monitor external systems. For localization consistency, one project involved using large language models to build glossary systems and lint tools, reflecting on the challenges of maintaining linguistic accuracy in complex software. Furthermore, a project focused on the translation of the game Morrowind, tes3-es, utilized LLMs to enhance localization by analyzing the game's data file format.

Further projects focus on user experience and media organization. One initiative involves creating a website for discovering first names that prioritizes an enjoyable browsing experience over traditional database query presentation, focusing on intuitive flow and visual design. Another project concerns streamlining media archiving by organizing photo repositories and establishing logical metadata extraction pipelines. On a personal productivity note, one system addresses the issue of excessive online content consumption by blocking feeds on iOS. Finally, there is work on applications designed to reduce friction in niche areas, such as tools for discovering local music and drink specials, and a typed, functional-imperative full stack programming language with integrated IDE support.
