Building a donations powered marketplace, zero platform fee: https://shomp.co Merchants who want to sell on Etsy or Shopify either have to pay a listing fee or pay per month just to keep an online store on the web. Our goal is to provide a perpetually free marketplace that is powered solely off donations. The only fees merchants pay are the Stripe fees, and it's possible that at some volume of usage we will be able t…

How's your API? I often consider putting together a sort of algorithmically driven print-on-demand storefront.

I want to be able to script prices, product descriptions, things like that. And see them show up in a request on sale.

Working on an AI governance and security platform that gives security and GRC visibility into what AI tools people are actually using but also what is going into them.

https://jiffylabs.ai/

It's a browser extension right now and the platform integrates with SSO providers and AI APIs, to help discover shadow AI, enforce policies and creates audit trails. Think observability for AI adoption but also Grammerly since we help coach endusers to better behavior/outcomes.

Early days but the problem is real, have a few design partners in the F500 already

A monster trainer game where you can _actually teach new, creative moves_ to your monsters: https://youtu.be/ThOCM9TK_yo

Basically, think of it as "Pokemon the anime, but for real". We allow you to use your voice to talk to, command, and train your monster. You and your monster are in this sandbox-y, dynamic environment where your actions have side effects.

You can train to fight or just to mess around.

Behind the scenes, we are converting player's voice into code in real time to give life to these monsters.

If you're interested, reach out!

I've been working on: - A front-end library that generates 10kb single-html-file artifacts using a Reagent-like API and a ClojureScript-like language. https://github.com/chr15m/eucalypt - Beat Maker, an online drum machine. I'm adding sample uploads now with a content accessible storage API on the server. https://dopeloop.ai/beat-maker - Tinkering with Nostr as a decentralized backend for simple web apps.

Great job on Beat Maker. It's very pleasant to use!

Thank you!

An open source website I built to explain tensor functions in PyTorch: https://whytorch.org It makes tricky functions like torch.gather and torch.scatter more intuitive by showing element-level relationships between inputs and outputs. For any function, you can click elements in the result to see where they came from, or elements in the inputs to see how they contribute to the result to see exactly how it contributes…

Awesome work. Surprised rand isn't implemented yet, I found it pretty useful for playing around.
