24 alternatives to Snowbin – A Mindmap-Based Social Platform Built with Lisp
I built a mindmap-based discussion platform, but what made the project truly interesting was not the UI — it was building the backend in Common Lisp. Inspired by Paul Graham and his book The Hacker and the Painter, I wanted to experience what it feels like to design a system in a language built for abstraction rather than convention. Instead of relying on a large framework, I combined small libraries and built a minimal internal structure myself.

The book page links to a blog post that explains how I got about it (and has a link to sample content), but the TL&DR is that I could not find a lot of books that were on "our" history _and_ were larded with technical details. So I set about writing one, and some five years later I'm happy to share the result. I think it's one of the few "computer history" books that has tons of code, but correct me if I'm wrong (I wrote this both to tell a story and to learn :-)). My favorite languages are Smalltalk and Lisp, but as an Emacs user, I've been using the latter for much longer and for my…

Hey HN. I wanted to share an update to our previous thread, “Notion with problem solving capabilities”. The Decipad public beta is now live. You can try it for free here. https://www.decipad.com/ We started building Decipad to make numbers more expressive and playful. It’s a notebook environment where you can combine text, numbers, data and calculations into a story. Our goal is to help people communicate with numbers more effectively and collaborate across diverse backgrounds. It’s feels a bit like Notion, but it’s for building interactive models and reports. A few things…

This is a Discord bot I made, which lets you write and evaluate Lisp code in collaborative sessions on Discord. I wrote it in a short amount of time, partly for learning purposes, but also because I found the idea exciting and it was fun to hack around. I'd be happy to get your feedback, especially on how to improve the deletion mechanism (maybe make deletion sexpr-based?). I've tried to make the README detailed enough so that it's easy to make some changes and run your own version.

Hey HN - my name is Tim and I created Slatebox. Slatebox is a visualization collaboration platform that lets you create editable mind-maps, diagrams, SWOT Analyses (w 100s of other templates) and more -- all based on natural language through AI. It's like Miro but with AI superpowers. Would love to know what you think. I'll be releasing a team pro version soon where teams can auto-diagram their internal ecosystem, including code repositories.

Im working on a mind mapping app that would allow for integration of gamification features and be nicer and easier to remember. I was missing more advanced graphics from apps and being able to treat it as my note taking and learning tool. i.e. how (and why?) should I remember a mind map if it looks the same like all other maps and all i can do is pick couple of shapes and dashed/dotted lines? this simply doesnt work with my brain so i decided to create something better :) map on page is a preview of this, but im curious about the quiz, typing games and cheatsheet, would love some…
