Show HN: I trained an AI model on 120M+ songs from iTunes

Hey HN!<p>I just shipped a project I’ve been working on called Maroofy: <a href="https://maroofy.com" rel="nofollow">https://maroofy.com</a><p>You can search for any song, and it’ll use the song’s audio to find other similar-sounding music.<p>Demo: <a href="https://twitter.com/subby_tech/status/1621293770779287554" rel="nofollow">https://twitter.com/subby_tech/status/1621293770779287554</a><p>How does it work?<p>I’ve indexed ~120M+ songs from the iTunes catalog with a custom AI audio model that I built for understanding music.<p>My model analyzes raw music audio as input and produces embedding vectors as output.<p>I then store the embedding vectors for all songs into a vector database, and use semantic search to find similar music!<p>Here are some examples you can try:<p>Fetish (Selena Gomez feat. Gucci Mane) — <a href="https://maroofy.com/songs/1563859943" rel="nofollow">https://maroofy.com/songs/1563859943</a> The Medallion Calls (Pirates of the Caribbean) — <a href="https://maroofy.com/songs/1440649752" rel="nofollow">https://maroofy.com/songs/1440649752</a><p>Hope you like it, and would love to hear any questions/feedback/comments! :D

Show HN: Sudoku with 0 Bells or Whistles

Hello HN,<p>I've created a new Sudoku app for iOS and Android that prioritizes simplicity and privacy. It's free to download and use, and I'd be grateful for any feedback or suggestions.<p>Features:<p>> 4 difficulty levels, accessible at any time<p>> No personal data collection of any kind<p>> Clean, minimalistic design that focuses on the game<p>> Takes up significantly less space than other popular apps (by a factor of about 10x)<p>> Minimal use of advertisements<p>I was frustrated by how many of the popular Sudoku apps feel excessively over-engineered, consume a lot of storage space and some that even collect unnecessary personal information, like location and contacts. So I put this app together without any of those things (using flutter).<p>Links:<p>iOS: <a href="https://apps.apple.com/app/sudoku-puzzle-palace/id1668683822" rel="nofollow">https://apps.apple.com/app/sudoku-puzzle-palace/id1668683822</a><p>android: <a href="https://play.google.com/store/apps/details?id=com.kingfishertech.sudoku">https://play.google.com/store/apps/details?id=com.kingfisher...</a><p>Here's a screenshot of the main app page: <a href="https://imgur.com/a/FbCf2IJ" rel="nofollow">https://imgur.com/a/FbCf2IJ</a><p>Thanks for taking a look and happy solving!

AI model on a $3 chip (ESP32)

We finished a design that allows a plug-and-play solution with TensorFlow Lite and a web server with the UI on ESP32. Here is a video of the process: <a href="https://youtu.be/aEZX3JMzwTo" rel="nofollow">https://youtu.be/aEZX3JMzwTo</a><p>I wanted to share the design in case anyone is interested as the camera is aimed at developers who want to play with AI models on the embedded side.

Show HN: KnifeGeek – Online Database of Pocket Knives

Hey HN! About a year ago i stumbled upon the world of swords, knives, and EDC gear. A weirdly addicting (and expensive) hobby to have.<p>Back then i noticed something, it was quite tedious to easily sift and search through knives based on length, steel, brand, and what not to find the knife for me. There were some great youtube channels that helped me pick out what i wanted however i had to sit through multiple 30 minute videos just to review 10-15 knives or so each.<p>Recently i've been having a little trouble sleeping so i decided to pickup a new passion project to work on late at night, here's KnifeGeek!<p>it's a completely free website where you can search, filter, and sift through an extensive knife database (over 60K+ knives) and add them to your collection or wishlist. You do need to sign in to add stuff to your wishlist or collection and after a bunch of advanced searches.<p>Please check it out and let me know if you think anything is missing! I'll try to flesh it out more on a daily basis if people find it cool or useful.<p>Planning to add in price comparison functionality and more data per knife in the next week.<p>PS: Images are a little shoddy, working on that.

Show HN: We built a developer-first open-source Zapier alternative

For the past few months we’ve been building Trigger.dev and can now share our beta with you: <a href="https://github.com/triggerdotdev/trigger.dev">https://github.com/triggerdotdev/trigger.dev</a>. Trigger.dev is an open source platform that makes it easy for developers to create event-driven background tasks directly in their code. You write workflows using our SDK, and can view all the runs in our web app.<p>Why we built this:<p>- We found current workflow / automation tools like Zapier and n8n are good for simple tasks, but not for more advanced use cases.<p>- Dropping down into code in these tools is just not a great experience. We prefer using our own IDEs, version control, and having access to GitHub Copilot etc.<p>- Sometimes, a workflow requires us to query a database or handle some sensitive information. It would be great if this data wasn’t sent to a third party.<p>Our beta version lets you:<p>- Trigger workflows from webhooks, custom events or schedules (CRON)<p>- Use API integrations with Slack, GitHub, Shopify and Resend. We’re adding more of these each week.<p>- Add delays of up to 1 year. Workflows will resume where they left off, even if your server has gone down.<p>- Support for Fetch and subscribing to generic webhooks.<p>- Observe every workflow run in the app (great for debugging).<p>- Open source MIT license so anyone can self-host the platform.<p>We’re still early so would love your feedback and opinions. Feel free to try us out for free – and if you want a specific API integrated, just let us know.<p>Main website: <a href="https://trigger.dev">https://trigger.dev</a> Github: <a href="https://github.com/triggerdotdev/trigger.dev">https://github.com/triggerdotdev/trigger.dev</a>
