License Info Q/A

Q: Say that a public github project does not have a license specified. Can I use that code in my own code?
A: No, if software is published without a license granting you rights to distribute that software, then in most countries you have no rights to distribute that software.
Just because it is available for download doesn't mean that it is in the public domain. In fact it is protected by the WIPO Copyright Treaty and thus the Berne Convention even if it is downloadable and even if it doesn't include a copyright notice - copyright is attached automatically on creation.
Q: Can I use any open source license?
A: No, any license you try to attach to that code would be void. Since you do not own copyright on the material, you cannot assign rights over that code to others.
