Atono▲189We kept asking "why did we build it this way?" and spending 20 minutes hunting through Jira, Slack, and GitHub for answers. It was a symptom of a bigger "Jira-problem". So we built Atono (https://atono.io). The idea: Stories that don't die when you ship. Everything - requirements, code changes, bugs, decisions - stays in one place. Our take (might not be for everyone): -Feature flags live in the story, not another tool -Feature engagement for you to see if people use what you built -Context > process What's in it: -Toggle feature flags right in the story -See usage graphs without…

https://lisagui.com/info.html This is a web OS I wrote in vanilla JS that looks like the Apple Lisa Office System (1983-85), with other contemporaneous influences and additional improvements and features. It's currently in alpha and isn't remotely bug free. I had been holding off on posting this here until it was somewhat presentable and useful. Please note; the Lisa conforms more literally to the desktop metaphor than most modern GUIs - some of the important differences are mentioned in the readme. This is a complete recreation of the UI in JS; it all renders to a single…

Tenno is a web app that lets you create Markdown documents that can include computational cells. You can think of it as a mix of Word and Excel, some sort of "literate programming" environment. This is still an early version but I wanted to get some feedback from HN on what could be nice features to add. Check out the Docs and examples page, it has a ton of (in my humble opinion) cool stuff! Why did I build this? I was building some estimation for cloud costs in Google Sheets and I quickly ended up with a mess. I realized that if I wanted to analyze how a certain thing changes wrt to…

I started writing Thoreau BASIC because I wanted a small, old-fashioned BASIC interpreter: line numbers, immediate mode, simple graphics, strings, arrays, the sort of environment where the computer starts with a "Ready" prompt and you can immediately make it do something. Then I wondered: why should it need an operating system? So I made it boot directly on x64 machines using UEFI. The UEFI version uses the Graphics Output Protocol for its framebuffer and gets its keyboard input directly from the firmware. There is no Windows or Linux underneath it. The machine boots into BASIC. It supports…
