VirtualBox> Ubuntu >Atom I know HN love to hate Atom, but it works tolerably out of the box on Python, SQL, XML, JSON, Markdown, HTML which covers most of my day job work.

I always have Notepad++ installed on Windows for quick edits, config files etc. Git Bash is helpful on Windows too as it adds a few useful bash tools, I can SSH properly (with keys) to my other machines for example.
