I stole mine… at least that is how I remember it. I was a beta tester for Ragnarok Online way back in the day and there was a user run site with info on mobs and items from the game. I liked the name Nitros so much the next game I played I registered the name Nitros7. Since then I have used a version of that name pretty much where ever I go.
At work I am chained to M$ platform so I am split between Notepad++ and PowerShell ISE.
On my personal systems its all VIM.
