Show HN: Infinite horizontal arrays of text editors
I made this app to write books chapter by chapter, while taking & browsing through temporary notes for each chapter.<p>The leftmost sidebar is the list of chapters. The sidebar to the right of that is the list of editors in the current chapter.<p>The UI & UX are a bit weird, but they have a basic logic to them.
Show HN: Ricotta – Language Learning to Replace Anki
I’ve been tinkering with Ricotta for about a year now and I'm happy to announce it’s ready to for others to use officially. Largely the time has been spent making the project a framework to spin up newer projects quickly which I can share details around if anyone is interested.<p>The app was born out of my frustration with Duolingo drilling me on words I knew. I moved on to creating custom Anki cards and found myself spending ages creating decks.<p>It’s free, uses spaced repetition under the hood, and focuses on helping you learn what you want to without a course structure.<p>I'd love to hear your thoughts or even feature requests: <a href="https://ricotta.affineur.io/" rel="nofollow">https://ricotta.affineur.io/</a>

Show HN: Global 3D topography explorer
I made a web app to generate 3D models of real places on earth from land cover and elevation data.<p>Click anywhere on the map to get a polygon, and then click "generate".<p>It should work at most scales, but if your watershed or region selection is too large, the result can be less exciting because it's so flat.<p>As a warning, the 3D models can sometimes be too much for my phone. It's nicer on desktop. I'm still working better on mobile support.<p>The land cover data I'm using gives a cool effect, but at some point I'd like to add in global imagery and clouds.<p>The backend is a Python thread running on an old Lenovo Thinkcentre in my closet, so if it goes down, this is why. (I also sometimes need to restart it when the network card stops working... I really should figure out why sometime.)<p>If you find a really cool island or watershed, let me know and I can add it to the "favorites".

Show HN: HTML visualization of a PDF file's internal structure
Hi,
I've just finished a rebuild of this function and added a lot of new features: info, page index, minimap, inverted index,...
I think it may be useful for inspection, debugging or just as a learning resource showcasing the PDF file format.
This is a pet project and I would be happy to receive some feedback!
Regards

Show HN: Chez Scheme txtar port from Go
This is a loose port of <a href="https://golang.org/x/tools/txtar" rel="nofollow">https://golang.org/x/tools/txtar</a>, which concatenates files together and allows for a top-level comment.<p>The txtar format is specifically designed to be easy for humans to read and write by hand. It's perfect for test data.<p>The library itself tries to follow scheme standards by depending on only SRFIs (and if you're new to scheme like me, SRFI stands for "Scheme Requests For Implementation," and it's like a standard library). I hope this is a helpful showcase of a scheme library!<p>I'm also new to writing scheme, and if any experienced scheme/lisp devs are out there with feedback, that would be much appreciated.

Show HN: Daily-notes.nvim – fuzzy time journal and planning plugin
I wrote an nvim plugin that does fuzzy time parsing on plain english dates to help you create + organise periodic notes. I use it daily at work and home. Hope it's helpful to others. :)<p>note: not using NLP, LLMs or 'true' fuzzy parsing as per academic literature; just normal recursive descent parsing

Show HN: Searchable library of free audiobooks
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.<p>At the moment, I've included audiobooks from popular sources like Librivox, Project Gutenberg, and Lit2Go.<p>I'm open to suggestions on additional free audiobook sources I could integrate into the site to expand the collection!
