Copyright applies by default. You do need to choose a license:

> When you make a creative work (which includes code), the work is under exclusive copyright by default. Unless you include a license that specifies otherwise, nobody else can use, copy, distribute, or modify your work without being at risk of take-downs, shake-downs, or litigation. Once the work has other contributors (each a copyright holder), “nobody” starts including you.

``` println!("gosh, no LICENSE!"); ```

I just published some source code without choosing a license.

(Yes, yes, I do licence my actual projects. But letting legalistic bullshit put people off releasing their source, even by a microscopic amount, is something that I disapprove of strongly.)
