Show HN: GTFS·X – a free, web-based transit schedule (GTFS) editor
Editing a bus route or schedule shouldn't require expensive software that's difficult to learn, so I built a free, web-based editor that transit agencies can use for free (or pay a nominal fee for cloud-based schedule hosting). Find your local bus service using "Search Catalog" from the "Import" button or explore a demo feed at https://www.gtfsx.com/demo
Built with Claude Code. Hosted on CloudFlare.

Show HN: World Flavor Atlas. Radzikowski and Chen's food embeddings in 3D
After reading the paper (https://arxiv.org/abs/2605.22391), I started playing with a visualization that helped me understand it more deeply. This is the result. Hope you enjoy it!

Tell HN: Building an Activist Developer Collective
Resistbot (and the more controversial ICEBlock), among others showed that a simple app with the right idea and distribution can move thousands of people to act, and I don't think we've come close to exhausting what's possible there, especially considering how AI / agents have empowered small dev teams.
I'm putting together a group of activist developers focused on brainstorming, hacking, shipping, and promoting activist tech end-to-end, and seeing what gains traction. We already have a few very talented devs. To be effective, we need a point of view. We lean anti-authoritarian, pro civil liberties, and more socially progressive than not. Practical idealists. If that’s not your thing, no sweat.
As a jumping-off point, I've pitched a WIP real-time boycott app (intercepts checkout flows, analyzes any product/company dynamically, suggests alternatives), but your ideas are as valuable than your time.
If you have an activist project that needs sharp technical people, come pitch it! If you just want to see where you can contribute any amount of time or expertise, we'd love to have you. Email me for an invite: books.elevens.8b@icloud.com

'X-Men '97' Season 2 Trailer Shows It's About Apocalypse Now

Show HN: Demon – open-source real-time music diffusion engine, 25Hz local GPU
YO,
I’m Ryan, lead author. I’ve been contributing open source generative audio stuff for a while now, audio reactive Comfy nodes, extended ACEstep support in Comfy, etc.. I just opened-sourced a new audio project that I've been working on for a few months and I want to tell y'all about it.
WHAT IS IS DEMON: Diffusion Engine for Musical Orchestrated Noise
This is StreamDiffusion but with audio instead of images, and ACEStep 1.5 instead of Stable Diffusion. It’s responsive enough that you can play it like an instrument, and remix in near real-time.
I also distilled the ACEStep VAE: it’s faster at the expense of some quality.
I also trained something like 200 lora/dora for ACEStep 1.5 and 1.5XL: I will release these in batches of 5 or 10 or something
WHY IT IS Two reasons: 1) Making music is an inherently real-time activity 2) Why not bro
SOME RUNTIME CAPABILITIES -Real-time remixing of songs -Denoise, structure, timbre strength adjustment -Reference track swapping -Prompt blending, parameter scheduling with curves -LoRA hotswapping, runtime strength adjustment -Latent channel (research preview) -Feedback -Vocal stem cutting/pasting with melformer (s/o u/BuffMcBigHuge) -XL support (its less stable, working out VRAM pressure issues and whatnot) -Lyrics/vocals SOON -Spectral quality SOON -Other stuff
SOME LIMITATIONS -ACEStep (correctly) ‘begins’ and ‘ends’ the song. This system is optimized for remixing either an entire song, or continuously remixing a loop. The loop works fine, but this is not pure, continuous music. Autogression wins here. -Many others, for a more exhaustive list, please see the full writeup via the project page -Please let us know if you find any, I would love to try and address them if possible
