Products that do what World Music Textbook, a collaborative open educational resource does
The World Music Textbook is a new collaborative effort to create a free and broadly accessible resource for the general public, educators, students, and researchers alike. Its open collections of scholarly, peer-reviewed writing and multimedia materials focus on increasing access to underrepresented voices, writing styles, and audiences, all with undergraduate students and a broad readership in mind. We have a post in the News section with some detail about our tech stack, which is all based on free/free tier services. One of the big goals is to make something reproducible in a way that…

Hi HN! I'm currently a Master's student at USTC (University of Science and Technology of China). I've been diving deep into Data Engineering, especially in the context of Large Language Models (LLMs). The Problem: I found that learning resources for modern data engineering are often fragmented and scattered across hundreds of medium articles or disjointed tutorials. It's hard to piece everything together into a coherent system. The Solution: I decided to open-source my learning notes and build them into a structured book. My goal is to help developers fast-track their learning curve. Key…

Hello HN, Over the last 12 months, I have been building https://learnawesome.org This idea came from Danny Hillis' 2012 talk at OSCON, which itself was inspired from Neal Stepehenson's _The Diamond Age : A Young Lady's Illustrated Primer_ The dream is to build a tool that matches the right learning material to the right student at the right time. Wikipedia is great, but it doesn't do a good job of leveraging the rich variety of learning resources that exist on the Web. Same applies to GoodReads - which is focused only on books, whereas these days we actually learn from videos,…

I noticed that many websites offering free audiobooks tend to have clunky search functionality, making it harder to find what you're looking for. To address this, I’ve created a site that aggregates audiobooks from multiple platforms—complete with book reviews and ratings—making it easier to discover and explore new titles. At the moment, I've included audiobooks from popular sources like Librivox, Project Gutenberg, and Lit2Go. I'm open to suggestions on additional free audiobook sources I could integrate into the site to expand the collection!

Hey HN. I’m Ivan, hacker from Ukraine. For about a year, I was working on Listenly — an app to listen to text content with OpenAI's natural-sounding text-to-speech model. At some moment, I realized that it would be cool to take all the public domain e-books and create audio versions for them. So I did it... kind-of. It would cost an immense amount of money to generate all the audio right away (OpenAI TTS costs approximately $0.84/hour of audio; 11labs, for comparison, is 10 times more expensive). So, I took a more gradual approach. I took all the metadata from the Project Gutenberg…

As an enthusiast of Indian classical music, I needed to write music notations in the traditional typeset format. When I didn't find any existing editors, I developed a Swara Notebook, a mobile focused web app to write North Indian Classical (Hindustani) music notations. The notes (called Sargam, similar to Solfege) can be written in English, Devnagri and Bangla scripts. The transcribed song can be played back in 6 different rhythmic cycles (Taal) to the accompaniment of the Tabla(a type of drum) or a metronome. Here's an example of a transcribed song…
