WaveFunctionCollapse
Bitmap & tilemap generation from a single example with the help of ideas from quantum mechanics
Project mention: Generating an infinite world with the Wave Function Collapse algorithm | news.ycombinator.com | 2025-01-18https://github.com/mxgmn/WaveFunctionCollapse
As for global repetition, the original repo did have this to say, that selecting tiles is important.

SwarmUI
SwarmUI (formerly StableSwarmUI), A Modular Stable Diffusion Web-User-Interface, with an emphasis on making powertools easily accessible, high performance, and extensibility.
Project mention: Show HN: Open-source app builder for comfy workflows | news.ycombinator.com | 2024-09-28Nice to see new things. Does your team know about SwarmUI[1]?
SwarmUI has been nice for sharing workflows with friends who might not want to learn ComfyUI, they can type in a prompt or any other config exposed in the workflow and even upload image input. It’s pretty good.
I would still like to see a web interface for workflows that is more-so built for indie hackers. I’d like to see a Next.js frontend that calls the ComfyUI on a server, it has a specific workflow configured for that app, and the server could be reused for another Next.js frontend, all that needs to change is the workflow. Letting you create multiple web apps with 1 Comfy backend.
Will keep tabs on viewcomfy, good luck!

This C# project serves as an data plumbing layer for some machine learning models. See you hear data the first thing that should come in your mind is Python. Unfortunately this was not the case, and to make it better it is using the .NET extension for Apache Spark. Migrating it to Python makes sense, since it is using rather non-standard technology for the problem, which makes hiring future talent rather difficult. And there are other obvious problems, common in other enterprise OOP languages as well, like mulitple levels of abstraction, inheritance everywhere, inversion of control, again things you do not do in data plumbing. And to futher feed the devil, the original team of contractors/consultants (because who else would use C#, than some enterprice consultant) are going to leave next month.
