Show HN: Write.md, a free, open-source, themeable Markdown editor for macOS
I’m going to post this every time there’s a new markdown to pdf submission: quarto (https://quarto.org) is my go to tool. You can use it in R Studio, visual studio code or the cli. Uses pandoc under the hood, has support for latex and many more niceties. - Source: Hacker News / 23 days ago
How I turned a static site into a fully agentic AI course site using MCP and AI agents
We chose Quarto. You write .qmd files, run quarto render, and get static HTML. We deploy that output to Cloudflare Pages. Pages load fast. URLs stay clean. Everything lives in Git. Learners can fork the repo and follow along. For a free, open cohort, that foundation was exactly right. - Source: dev.to / 3 months ago
Why the heck are we still using Markdown?
I'm in no way saying that markdown is perfect but it is much better than anything else I've used. It's got me through both a bachelors and masters. The author of this article appears to be unaware of pandoc, and even better quarto. I started with pandoc and various plugins and my own scripts but moved to quarto, it is excellent. https://quarto.org/. - Source: Hacker News / 5 months ago
