Atom is an open source "hackable text editor for the 21st Century" developed by GitHub, which is currently in beta. Currently, there are Atom binaries only for Mac OS X. Until now, to use Atom in Ubuntu you'd have to compile it but I like to make things easier for you so I've built it on my computer (Nodejs apps can't be built directly in Launchpad PPAs) and uploaded it to a PPA, for Ubuntu 14.04, 13.10 and 12.04. The text editor is based on web technologies and features Node.js integration, allowing you to seamlessly mix usage of Node and browser APIs. And of course, since it's developed by GitHub, it features built-in Git integration.
