Flatdoc
Build sites fast from Markdown
Flatdoc is a tiny JavaScript library that builds a documentation site directly from Markdown files, without requiring a server-side engine or static site generator. Point it at a Markdown source and it fetches, parses, and renders content into a ready-to-browse doc layout in the browser. It autogenerates a navigation sidebar from headings, supports anchors, and provides a clean default theme that’s easy to restyle. Because it runs client-side, it’s great for small projects, GitHub-hosted docs, or internal references where you want “drop-in” documentation with minimal setup. The library’s footprint and API are intentionally modest, making it simple to customize templates, typography, or color schemes. For teams who value instant docs from a README or single Markdown file, Flatdoc remains a practical, dependency-light choice. -

Atom Linux
The hackable text editor
Atom is a hackable text editor for the 21st century, built on Electron, and based on everything we love about our favorite editors. We designed it to be deeply customizable, but still approachable using the default configuration. A set of encrypted code signing certificates were exfiltrated; however, the certificates were password-protected and we have no evidence of malicious use. As a preventative measure, we will revoke the exposed certificates used for the Atom application. Revoking these certificates will invalidate some versions of Atom. When we introduced Atom in 2011, we set out to give developers a text editor that was deeply customizable but also easy to use—one that made it possible for more people to build software. While that goal of growing the software creator community remains, we’ve decided to retire Atom in order to further our commitment to bringing fast and reliable software development to the cloud via Microsoft Visual Studio Code and GitHub Codespaces.
