UNIX / Linux Tutorial for Beginners

Step 2

Deed

Question

An early-2000s introductory UNIX/Linux tutorial written by a UK-based academic and made freely available online states that it is distributed under an older Creative Commons license version, and it links to a canonical URL ending in “/2.0/”. Identify the exact Creative Commons license (full name and version) applied to this tutorial. Then, based on the official license deed, explain in detail: (1) the freedoms it grants users, (2) the specific conditions users must follow (including attribution, commercial use, and derivative works), (3) any stated limitations or disclaimers (such as warranties or additional rights), and (4) the notice regarding the recommended newer 4.0 version of the license.

Answer length: 200-300 words.

Depth checklist

Creative Commons Attribution-NonCommercial-ShareAlike 2.0 + Identified via canonical URL ending in /2.0/
Recognition that this is an older license version with an official notice recommending the 4.0 version

Width checklist

Correct identification of the freedoms: Share (copy and redistribute) and Adapt (remix, transform, build upon)
Statement that freedoms cannot be revoked if license terms are followed
Attribution requirement (credit, link to license, indicate changes, no implied endorsement)
NonCommercial restriction (no commercial use)
ShareAlike requirement (derivatives must use the same license)
No additional restrictions clause
Mention of public domain/exception limitations
No warranties disclaimer and note about other rights (e.g., privacy, publicity, moral rights)
Reference to recommendation of the newer 4.0 version as more user-friendly and internationally robust

Examiner rationale

The question uses contextual clues (early-2000s UNIX/Linux tutorial by a UK academic with a CC license URL ending in /2.0/) to require logical identification of the specific Creative Commons license version (Deep reasoning). It then requires comprehensive synthesis of multiple sections of the official license deed—freedoms, conditions, disclaimers, and upgrade notice—ensuring broad aggregation of details from the license text itself (Wide scope).

Judgment

Better

DEEP

Score 1 - 0

First, Deep Logic: Agent A identifies the license as Creative Commons Attribution-NonCommercial-ShareAlike 2.0 (generic) with a canonical URL ending in /2.0/, which matches the constraint. Agent B instead specifies the 2.0 UK: England & Wales port (/2.0/uk/), which does not align with the canonical /2.0/ requirement. Therefore, B has a Deep Logic failure (wrong specific license variant). Next, Width/Completeness: Both agents correctly describe the core freedoms (Share, Adapt), attribution, NonCommercial, ShareAlike, fair use exceptions, no warranties, and the 4.0 recommendation. However, both omit explicit mention of the “no additional restrictions” clause and do not clearly state that freedoms are irrevocable provided terms are followed. So both are slightly incomplete on the WIDTH checklist. Finally, Presentation & UX: Both are well-structured and readable. Agent A has slightly clearer section formatting and more precise alignment with the generic license deed. Since A is accurate on the core entity and B is not, A wins. However, because A also misses minor checklist elements, this is [[A_BETTER]] rather than MUCH_BETTER.

The tutorial is **"UNIX Tutorial for Beginners"** by Michael Stonebank at the University of Surrey, UK. It is licensed under the **Creative Commons Attribution-NonCommercial-ShareAlike 2.0 License** (CC BY-NC-SA 2.0), with the canonical deed URL ending in `/2.0/` [1][2]. **(1) Freedoms Granted:** The license grants users two core freedoms. First, users may **copy, distribute, display, and perform** the work. Second, users may **create derivative works** (adaptations, remixes, transformations) based on the original material. These freedoms apply worldwide and are granted free of charge [3]. **(2) Conditions Users Must Follow:** Three specific conditions apply. **Attribution (BY):** Users must give appropriate credit to the original creator, provide a link to the license, and indicate if changes were made, in a reasonable manner. **NonCommercial (NC):** Users may not use the work for **commercial purposes**—the material cannot be used primarily for commercial advantage or monetary compensation. **ShareAlike (SA):** If users remix, transform, or build upon the material, they must distribute their contributions under the **same or compatible license** as the original [3]. **(3) Limitations and Disclaimers:** The license explicitly states it does **not** affect fair dealing/fair use rights or other applicable exceptions. It provides **no warranties**—the work is offered "as-is." The licensor is not required to grant additional permissions beyond those stated. Moral rights and rights of other persons (e.g., publicity, privacy) may still limit use [3]. **(4) Notice Regarding the Newer 4.0 Version:** The official CC BY-NC-SA 2.0 deed now displays a prominent notice informing users that this is **not the latest version** and recommending they consider using **Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International** for their own works, which is the most current and internationally standardized version of this license [3]. ## References [1] Stonebank, M.

The tutorial "UNIX Tutorial for Beginners" by M. Stonebank of the University of Surrey is distributed under the **Creative Commons Attribution-NonCommercial-ShareAlike 2.0 UK: England & Wales** license [1, 2]. (1) This license grants users the **freedom** to Share (copy and redistribute the material in any medium or format) and Adapt (remix, transform, and build upon the material) [2]. (2) Users must follow several **conditions**. First is **Attribution**, requiring they give appropriate credit, provide a link to the license, and indicate if any changes were made. This must be done reasonably but not in a way that suggests the licensor endorses the new work. Second, the **NonCommercial** clause prohibits using the material for commercial purposes. Third, the **ShareAlike** condition mandates that if you remix, transform, or build upon the material, you must distribute your contributions under the very same license as the original [2]. (3) The license includes important **limitations and disclaimers**. It comes with no warranties, and the licensor provides the work "as-is" without assurances of any kind. This means the licensor is not liable for damages arising from its use. The license does not limit a user's rights from exceptions and limitations to copyright, such as fair dealing or fair use [2]. (4) The official Creative Commons deed for this 2.0 license contains a prominent **notice regarding newer versions**. It states that this is a legacy version and recommends against using it for new works. Instead, Creative Commons encourages creators to apply the more globally robust and user-friendly Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International license for new projects [2, 3]. ## References [1] Stonebank, M.
