What is the difference between GPL and FreeBSD

[blithen]

Yes obviously I don't know what the difference, and please be gentle to a noob.
GPL obviously means General Public License, but if you search FreeBSD, on google, it comes up with an operating system. (That is an assumption, I actually type in 'BSD' I don't know if that would make a difference.) So what is the difference, I've seen the two compared but to my knowledge one is an Operating System, and one is a license.

BSD is a software license, I happen to still have the wording of it in my clipboard coincidentally enough.

Clauses 3 and 4 are not in every copy of the BSD license, however.

So...in what ways are they different? They are very basically the same. Both allow the modification of a program, and to use it as your own. Unless FBSD is a distributing purposes, and GPL is well general use of the program, and modifying it yourself without distributing it.

FreeBSD is an operating system. The BSD license is what you're talking about. No F. :P

The main difference is that code derived from BSD code can be distributed in any form as long as the copyright remains in tact, the GPL must be distributed with the source code with the copyright remaining in tact.

The other main difference is the GPL is about six miles longer than the BSD. :lolflag:

@ryno519 > There are actually many variants of the BSD licence. The one you quoted is the "four-clause" one, which is not used anymore except in NetBSD. Most people today use a two-clause licence, which goes like this :

Occasionnally, they add a third clause, which is the same as the fourth one in the version you posted. The third one, better known as the "advertising clause", has been removed to make the licence GPL-compatible.

Gah! Finally. Thank you. I understand now. :D

The other main difference is the GPL is about six miles longer than the BSD. :lolflag:I was going to ask... where is the rest of the license. I tried reading the GPL a few nights ago and wound up cracking my head open on the keyboard when falling asleep!

That thing should come in a split-html format... geeeeesh!

The big difference between that GPL and FreeBSD licenses comes if you distribute the code or a derived work based on the code. The GPL is known as a copyleft license and is designed so that Free (as in speech) software remains Free when it or a derived work based on it is distributed. The idea is that everyone who gets GPL code also gets as Free Software. On the other hand code licensed under a FreeBSD license can be incorporated into a propriety application.

A good starting place to learn about Free Software and copyleft licenses such as the GPL is the Free Software Foundation http://www.fsf.org
