I'm sorry if this is the wrong place, but I don't see any forum here that's more appropriate. Does anybody know about how the "brief passage" exception to US copyright law applies to code?

For instance, let's say a somebody (not me) is giving a workshop on good programming practices to Computer Science students. S/he wants to use code snippets written by people she knows and/or worked with in the past. Does s/he need written permission?

Thanks. If this is the wrong place please redirect.

are they going to give them credit?

In other words, you are saying it has to be fully attributed. I got it. Thanks a lot.

I think you need prior permission.

You don't need permission for the "brief passage" exception. She should just ask for permission, it's not like brief snippets of code are particularly valuable and it's not likely they'll deny it.
