Ledge.sh – Runnable Markdown Notes

In plain words

Ledge is a Markdown notebook for developers and DevOps that executes code blocks directly within notes. Users can run shell commands, code, SQL, and AI prompts by pressing a keyboard shortcut, with output displayed immediately below each block. The persistent shell environment maintains state across runs, preserving directory changes and variables. Available free and open source for Mac and iPhone.

  Makedown – A Markdown powered Makefile alternative2024 · github.com · ▲142

  `makedown` allows you to organise your shell scripts in one or several markdown files, by mix and matching different scripting languages for various commands and needs. zsh/bash/sh, python, javascript or anything else available on your system. Handy for replacing one-line-based package.json scripts or shell-based Makefiles. One can also write documentation and explanations to various commands in the same `.md` file. Most editors highlight correctly most languages in the markdown code blocks, even when you use several scripting languages. Here is a demo .md file…

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
