UNIX / Linux Tutorial for Beginners

Step 2

Deed

Question

An early-2000s university-created UNIX/Linux tutorial for beginners is distributed under a Creative Commons license that permits sharing and adaptation but restricts commercial use and requires derivatives to carry the same license. Identify the exact Creative Commons license version that matches these conditions, and explain in detail: (1) the freedoms it grants to users, (2) the obligations imposed on users (including attribution and distribution requirements), (3) any statements about revocability of freedoms, (4) disclaimers regarding warranties or other rights, and (5) any official notice comparing this version to a newer, more internationally robust 4.0 version.

Answer length: 200-300 words.

Depth checklist

Creative Commons Attribution-NonCommercial-ShareAlike 2.0 (CC BY-NC-SA 2.0) identified as the license matching the share/adapt + noncommercial + sharealike conditions
Recognition that the license includes an official notice comparing it to the newer 4.0 version and recommending adoption of 4.0 for new works

Width checklist

Correct identification of the freedoms: sharing (copy and redistribute) and adapting (remix, transform, build upon)
Statement that freedoms are irrevocable provided license terms are followed
Attribution requirement (credit, link to license, indicate changes)
NonCommercial restriction (no commercial use)
ShareAlike requirement (derivatives must use the same license)
No additional restrictions clause (no legal/technological barriers beyond license terms)
Disclaimer of warranties and note about possible additional rights (privacy, publicity, moral rights)
Notice stating this is an older version and recommending the 4.0 version as more user-friendly and internationally robust

Examiner rationale

The question uses deep logic by requiring identification of the specific Creative Commons license version that matches the described combination of permissions and restrictions, without naming it directly. It uses wide aggregation by requiring detailed synthesis of multiple clauses from the license text—freedoms, conditions, revocability, disclaimers, and the comparison to version 4.0—ensuring the respondent must consult and integrate information from the full license summary rather than a single isolated fact.

Judgment

WIDE

Score 0 - 1

Both Agent A and Agent B correctly identify the license as Creative Commons Attribution-NonCommercial-ShareAlike 2.0 (CC BY-NC-SA 2.0), so both pass the DEEP logic check. On WIDTH/Completeness: Both cover the core freedoms (sharing and adapting), attribution, NonCommercial, ShareAlike, irrevocability (conditional on compliance), warranty disclaimers, and the recommendation to use 4.0. However, Agent A omits a clear explanation of the "No additional restrictions" clause (i.e., prohibition on adding legal or technological barriers such as DRM). Agent B explicitly mentions the prohibition on technological measures and distribution requirements, satisfying that checklist item more fully. Agent B also gives a more precise comparison to 4.0 (international robustness, database rights, jurisdictional improvements). On User Experience: Both are well-structured and readable, but Agent B is slightly more legally precise and complete while remaining concise. Citation density is also higher and more granular. Therefore, Agent B wins on superior completeness and precision (WIDE), with no major factual errors from either side.

The tutorial in question is the **UNIX Tutorial for Beginners** created by the University of Surrey, licensed under **Creative Commons Attribution-NonCommercial-ShareAlike 2.0 (CC BY-NC-SA 2.0)** [1][2]. **(1) Freedoms Granted:** This license grants users the right to **copy, distribute, display, and perform** the work, as well as to **make derivative works** based on it. These freedoms apply to anyone, provided the license conditions are met [2][3]. **(2) Obligations Imposed:** Users must satisfy three key conditions. **Attribution (BY):** Users must give appropriate credit to the original creator, provide a link to the license, and indicate if changes were made. **NonCommercial (NC):** The work may not be used for commercial purposes. **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. These obligations ensure the work remains freely accessible under equivalent terms [2][3]. **(3) Revocability:** The CC BY-NC-SA 2.0 license states that the licensor **cannot revoke these freedoms** as long as the user follows the license terms. Once granted, the rights are irrevocable under compliance [3]. **(4) Warranty Disclaimers:** The license explicitly disclaims all warranties. It states the work is provided "as-is" with **no warranties of any kind**, including merchantability or fitness for a particular purpose. It also notes that the license may not address all relevant rights, such as moral rights, privacy, or publicity rights [3]. **(5) Notice Regarding Version 4.0:** Creative Commons officially notes that version 2.0 has been **superseded by the 4.0 version**, which is more internationally robust, legally thorough, and better suited for global use. Creative Commons recommends users consider applying the **4.0 license** for new works [4]. ## References [1] University of Surrey, "UNIX Tutorial for Beginners," http://www.ee.surrey.ac.uk/Teaching/Unix/ [2] Creative Commons, "Attribution-NonCommercial-ShareAlike 2.0 Generic," https://creativecommons.org/licenses/by-nc-sa/2.0/ [3] Creative Commons, "CC BY-NC-SA 2.0 Legal Code," https://creativecommons.org/licenses/by-nc-sa/2.0/legalcode [4] Creative Commons, "License Versions," https://creativecommons.org/choose/results-one?license_code=by-nc-sa&version=4.0

Creative Commons Attribution-NonCommercial-ShareAlike 2.0 Generic (CC BY-NC-SA 2.0) matches these conditions[1]. **Freedoms**: Users may copy, distribute, display, perform, and make derivative works for noncommercial purposes[2]. **Obligations**: Users must provide attribution to the creator, include a copyright notice, mention the license, and indicate if changes were made. Derivatives must be licensed under identical terms (ShareAlike)[3]. For distributions, users must provide a link to the license and not use technological measures to restrict others from exercising rights granted by the license[4]. **Revocability**: The license is perpetual but non-exclusive; licensors cannot revoke freedoms as long as users follow license terms[5]. **Disclaimers**: The work is offered "AS-IS" with no warranties. The licensor is not liable for damages arising from use[6]. This does not affect other rights like fair use or moral rights[7]. **Comparison to 4.0**: CC BY-NC-SA 4.0 is more internationally robust, using globally applicable terminology and addressing database rights. Version 2.0 uses jurisdiction-specific ports and may not address all sui generis rights[8]. ## References 1. Creative Commons.
