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.

What it does
About Snowbin is a social platform where conversations happen on a mind map—not a chat-based mind map generator, but a structured communication space. Traditional linear chats like Slack or Discord mix different topics in one stream, making discussions chaotic and hard to follow. Important ideas get buried, and focus drifts to minor branches. Snowbin solves this by letting people talk directly on a mind map, keeping conversations organized, visual, and logically structured from the start.

- IWI wrote a technical history book on LispFeb 2026 · berksoft.ca · ▲252
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…

- ANA Notion-like platform for building interactive models2023 · decipad.com · ▲88
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…
