On intellij IDEA, there's a fantastic feature:

Saving code in a gist

    Select the code to be shared by doing one of the following:
        To have a piece of code from a single file shared, open the file in the editor and select the required code snippet. If no selection is made, the gist will contain the entire file.
        To have the code from a file shared, select the file name in the Project view.
        To create a gist from a folder, select the folder in the Project view.
        To create a gist from several files or folders, select them in the Project view.
    On the context menu of the selection, choose Create gist.

sometimes using git is just overkill, this is a convenient, poor-mans version control and quite useful for posting code or config for review.
