I build djit.su during the coronavirus lockdowns – a new code editor
TL;DR: During the coronavirus lockdowns I built a new kind of code editor - a notebook-like development environment inspired by the awesome teachings of Bret Victor. Check it out: https://djit.su Quick backstory: I've always wanted to create a different kind of code editor that encompasses several aspects of what I consider programming.

In the maker’s words, at launch
TL;DR: During the coronavirus lockdowns I built a new kind of code editor - a notebook-like development environment inspired by the awesome teachings of Bret Victor. Check it out: https://djit.su Quick backstory: I've always wanted to create a different kind of code editor that encompasses several aspects of what I consider programming. I think it's started somewhere around the time Bret Victor had his famous talk - it blew my mind, seeing how he develops the game in real-time modifying variable and functions as he goes. About three months ago, as the corona lockdowns hit, the company I just recently started working at collapsed due to lack of funding. I started working on a thing. It began when I finished with my ObservableHQ Coronavirus Stats (https://observablehq.com/@elisk/coronavirus-stats) and wanted to extend the table with more features. Today I finally shipped what I consider truly first functional version of djit.su — a rudimentary yet-to-be-fully-defined tool that I designed in my mind for almost a decade, prototyped at least four different times in the last five years, and finally get to play with for the first time after building it for the past 3 months. I've created a quick reference example for how to update the cell value from the react component - check it out here: https://djit.su/dBqYwddyuP42QRe — it might serve you as a good point to get an idea how to interact with djit.su as the documentation is non-existing at this point. Any and all comments, suggestions, and recommendations are welcome.

Hi guys, Two days ago I published the fourth post in the series and thought it would now be a good time to look for additional feedback here on Hacker News. The aim of the series (as mentioned in the first post) is to inspire more people to start using Qt. My ambition is to answer the following questions "what is the gist of Qt?"; "what is the 20% that you need to know to develop 80% of the application?"; "what are the perhaps unknown unknowns?". In other words, I'm just covering basics: enough to understand the concepts and where to find additional information should you need it. Do you…
- IBI built a mockup/prototype/wireframe editor in ten weeks2012 · ▲42
Hi HN, After watching a lot of Show HN's here, it's finally my turn to show something. This is the first real project I have shipped, so it is extra special to me. For those who will inevitably ask why I made yet another mockup editor I covered it on our blog (http://blog.mocktailsapp.in/why-build-yet-another-mockup-editor-tm). Not all the features mentioned in that post have been implemented yet. As such Mocktails is pre-beta software and very minimal. It does not even have user accounts or any actual server side component at all for that matter (yet)! Our intention is to build Mocktails…
- ECEnable Claude to interactively debug your code2025 · github.com · ▲7
I participated in the Nvidia + Vercel 2 hour hackathon in SF tonight, and built something I've wanted, but hadn't tried building. I implemented an MCP Server and VS Code extension to allow Claude Desktop to place breakpoints, step through code, and execute expressions (assuming language support). So you can ask it a question that requires actually stepping through the code and now it can actually do that - check values for you, etc. It's _definitely_ not perfect. Have improvements? Please make a PR!
- TCThink, CL tool that makes AI your command line copilot (written in Go)2023 · github.com · ▲14
Hi HN, I'm thrilled to share with you think, a command-line tool that I developed while diving back into the programming scene. For the past few years, my focus had shifted from hands-on programming to managerial roles, my last one being at Affirm (I started Affirm's Polish office). However, I recently left my job to revisit my passion for coding and see if I could still write code that works. Not to mention that with what is currently going on in AI if you are a developer this probably the best possible time for a sabbatical in human history :) My first attempt was with LangChain, but I…
- IBI built new type of dev environment for agentic coding2025 · github.com · ▲6
The main goal of this was to be able to not just run multiple Claude Code sessions at once, but actually manage them and keep track of what I was doing. Sometimes this is multiple attempts on the same task, sometimes I work several tasks at once. Really I was just sick of twiddling my thumbs waiting for the coding agent to finish, and I wanted it to be easy to work on/review/test another change while I waited.
- AUAn update to our long-turn FreeCiv experienceMay 2026 · freeciv.andrewmcgrath.info · ▲5
So we have had quiet the journey here. So 70 days ago (aka 73 turns ago) I posted on HN sharing our FreeCiv deployment (https://github.com/ndroo/freeciv.andrewmcgrath.info). FreeCiv is a great game, the clients is very buggy however. I'm using the GTK4 version, but a few others have opted for the QT variant. At some point, we might turn our focus to contributing to improving the client based on our experiences playing the game. We've since added a lot of little fun features: - The editor: you can write to the newspaper Editor and they /might/ publish what you…
