Question 1 of 10
1. The idea for copyleft was to be the opposite of copyright. Though a recognized concept from long before, copyright law came into being after printing presses were invented, and a printer required a license to print a specific work. Today, copyright is a legal protection of a creator's rights to their work. Which of these is NOT protected by copyright? Hint


Question 2 of 10
2. One programmer/activist, still recognized by many as "rms", agreed to give some of his code to another group of programmers. However, when he asked for their improved code in return, they refused. Can you identify "rms"? Hint


Question 3 of 10
3. So, the idea for copyleft came from the computer software community. The idea was that programming code shouldn't belong to only one person/company, but be available to all to incorporate, modify and share. What is another word for software code that is owned by one company that licenses the right of use? Hint


Question 4 of 10
4. The first copyleft license was made available by GNU (GNU's Not UNIX). This is often called GNU GPL or just GPL. What does GPL stand for? Hint


Question 5 of 10
5. Copyleft licenses can be categorized as either strong or weak. A weak license allows that not all products created from the original will inherit the original license. Which of these licenses is considered to be a weak copyleft license? Hint


Question 6 of 10
6. The GNU GPL refers to free software, and because "free" has more than one meaning this has been the cause of some confusion. As used in the GPL, does it mean that there is no cost for the source code or the software program?


Question 7 of 10
7. Which operating system, originally developed by Linus Torvalds, was licensed under the copyleft GNU GPL? Hint


Question 8 of 10
8. If a programmer wants his software to be available to all for distribution and modification, copyleft is not the only available option. Which of these options also allows for free use and modifications? Hint


Question 9 of 10
9. Some opponents of copyleft licenses refer to them as viral because each of the end products must inherit the same licensing. Which of these pejorative terms was used to promote the viral argument? Hint


Question 10 of 10
10. Other copyleft licenses have been developed for art, music, and videos. Which of these non-profit organizations provides licenses free of charge? Hint

Quiz Answer Key and Fun Facts
1. The idea for copyleft was to be the opposite of copyright. Though a recognized concept from long before, copyright law came into being after printing presses were invented, and a printer required a license to print a specific work. Today, copyright is a legal protection of a creator's rights to their work. Which of these is NOT protected by copyright?

Answer: ideas

The intent is to protect the creator's rights for such things as books, computer software, films, art, photography, or other creative output. The copyright is generally only granted for a limited time. Once a copyright expires, the work enters the public domain.
2. One programmer/activist, still recognized by many as "rms", agreed to give some of his code to another group of programmers. However, when he asked for their improved code in return, they refused. Can you identify "rms"?

Answer: Richard Matthew Stallman

Richard Stallman's involvement in computers began during the 1960s. He was part of the hacker group at MIT. Hacker at that time defined a programmer either creating something new or perhaps modifying and improving someone else's code, and was something to seriously aspire to.

The incident described in the question occurred when the MIT hackers basically split into two camps to create a Lisp (LISt Processing) machine. The camp divisions were created because some of the MIT hackers thought that any profit should be reinvested in the company, and others thought that venture capital investments were the better option.

Thus the idea was planted to create a free software license.
3. So, the idea for copyleft came from the computer software community. The idea was that programming code shouldn't belong to only one person/company, but be available to all to incorporate, modify and share. What is another word for software code that is owned by one company that licenses the right of use?

Answer: proprietary

Proprietary software, owned by a single company or person, assigns rights to the users generally via an End User License Agreement.

Copyleft utilizes copyright law to enforce a license so that the item may be freely used, modified, and shared so long as the end product retains the same license, and source code is made available. Richard Stallman coined the copyleft term in approximately 1985.
4. The first copyleft license was made available by GNU (GNU's Not UNIX). This is often called GNU GPL or just GPL. What does GPL stand for?

Answer: General Public License

Richard Stallman eventually quit his job at MIT (though for a while he was still allowed to use their computers) to create software that could be freely distributed. He thought to begin first with an OS, because without it the computer doesn't compute. Thus began the GNU Project. The GPL was intended to be a more generic license (i.e., not tied to a specific piece of software or code) and to continue the practice of sharing code.

The first version of the GPL was released in 1989, and it has been revised several times since.
5. Copyleft licenses can be categorized as either strong or weak. A weak license allows that not all products created from the original will inherit the original license. Which of these licenses is considered to be a weak copyleft license?

Answer: Mozilla Public License

The Mozilla Public License (MPL) is maintained by the Mozilla Foundation, with products such as Firefox, and Thunderbird.

Not all copyleft licenses have the same requirements. The MPL license was created to be a compromise between the proprietary BSD license and the free GPL license.
6. The GNU GPL refers to free software, and because "free" has more than one meaning this has been the cause of some confusion. As used in the GPL, does it mean that there is no cost for the source code or the software program?

Answer: No

The GNU GPL (version 3, dated 6/29/07) states: "When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for them if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs, and that you know you can do these things."

In fact, you can indeed charge for the software that you've created using the GPL license. The license also specifies that the source code must be made available and that others may redistribute and modify it. Alternatively, if you never distribute what you created, then you do not need to make the code public.
7. Which operating system, originally developed by Linus Torvalds, was licensed under the copyleft GNU GPL?

Answer: Linux

The creation and distribution of Linux is one of the best known examples of a GNU GPL distribution. It was originally coded for Intel x86 systems, but has now been ported to many other hardware platforms. The code has been used to create other operating system variations such as Debian, Fedora and openSUSE.
8. If a programmer wants his software to be available to all for distribution and modification, copyleft is not the only available option. Which of these options also allows for free use and modifications?

Answer: public domain

Items in the public domain are there either because the rights have expired or have been forfeited. In addition, any work generated by the US Government is considered public domain.

A programmer's code is automatically copyrighted and the programmer must actively disclaim copyright.
9. Some opponents of copyleft licenses refer to them as viral because each of the end products must inherit the same licensing. Which of these pejorative terms was used to promote the viral argument?

Answer: General Public Virus

Soon after the first GPL license was released opponents began calling it "General Public Virus" or "GNU Public Virus". The major opponents were those that believed that the sharing of code would compromise their intellectual property.

There are many articles that report that the use of the word "virus" was intended to connote such a negative understanding of copyleft that programmers would discontinue using those licenses. The term is still in use today, and arguments continue.
10. Other copyleft licenses have been developed for art, music, and videos. Which of these non-profit organizations provides licenses free of charge?

Answer: Creative Commons

The Creative Commons focus was to be able to license a creator's rights based on a combination of the following: Attribution, Share-alike, Noncommercial and No Derivative Works. A creator could then combine these to create a license specific to their creation.
