UNIX / Linux Tutorial for Beginners

Step 2

Deed

Question

A well-known early-2000s beginner’s guide to UNIX and Linux commands, authored by a UK academic and made freely available for download and modification, is released under a specific Creative Commons license that predates the 4.0 suite. Identify the exact Creative Commons license (including version) under which such tutorials were commonly published at that time when marked “Attribution–NonCommercial–ShareAlike.” Then, based on the official license deed, explain in detail: (1) the freedoms granted to users, (2) the conditions users must follow, (3) any clauses about additional restrictions or revocation, (4) disclaimers regarding warranties or other rights, and (5) what the Creative Commons organization recommends regarding newer versions of this license.

Answer length: 200-300 words.

Depth checklist

Creative Commons Attribution-NonCommercial-ShareAlike 2.0 (CC BY-NC-SA 2.0) correctly identified as the pre-4.0 license matching the described tutorial
Logical link: Early-2000s UNIX/Linux tutorial marked 'Attribution–NonCommercial–ShareAlike' and predating 4.0 implies CC BY-NC-SA 2.0

Width checklist

Correct identification of freedoms: Share (copy and redistribute) and Adapt (remix, transform, build upon)
Statement that freedoms are irrevocable provided terms are followed
Attribution requirement (credit, link to license, indicate changes)
NonCommercial restriction (no commercial use)
ShareAlike requirement (derivatives under same license)
No additional restrictions clause (no legal/technological barriers beyond license terms)
Disclaimer of warranties and note about other rights (e.g., privacy, publicity, moral rights)
Mention that version 4.0 is recommended as more internationally robust and user-friendly

Examiner rationale

The question uses contextual clues (early-2000s UNIX tutorial, UK academic author, Attribution–NonCommercial–ShareAlike, pre-4.0) to require logical identification of the specific Creative Commons license version (Deep reasoning). It then demands aggregation of multiple dispersed elements from the official license deed—freedoms, conditions, revocation terms, disclaimers, and upgrade recommendations—ensuring broad information synthesis (Wide scope).

Judgment

Better

NONE

Score 0 - 1

First, Deep Logic: Both Agent A and Agent B correctly identify the license as Creative Commons Attribution–NonCommercial–ShareAlike 2.0 (CC BY-NC-SA 2.0), logically linking the early-2000s timeframe and pre-4.0 status. Both pass the core entity check. Second, Width/Completeness: Both cover the required checklist items—freedoms (Share and Adapt), irrevocability (conditioned on compliance), Attribution, NonCommercial, ShareAlike, no additional restrictions (no DRM/legal barriers), disclaimers (no warranties; other rights like moral/publicity), and recommendation of 4.0 as more robust. Agent B is slightly more explicit about irrevocability (“cannot revoke freedoms as long as terms are followed”) and adds helpful detail about patent/trademark rights and third-party claims, improving completeness. Finally, Presentation & User Experience: Both are clearly structured and scannable. However, Agent B provides slightly richer contextual grounding (naming the specific tutorial), clearer condition breakdowns, and more detailed disclaimer language. Citation density is also marginally higher. Since both are factually strong and well formatted, the distinction is based on marginal gains in clarity and comprehensiveness. Therefore, Agent B offers a slightly better overall user experience, but Agent A has no substantive failures.

The early-2000s “Attribution–NonCommercial–ShareAlike” Creative Commons license in wide use for free academic tutorials (including UK-authored UNIX/Linux guides) was typically **Creative Commons Attribution-NonCommercial-ShareAlike 2.0** (CC BY-NC-SA 2.0). [1][2] 1. **Freedoms granted** Users are free to **share** (copy, distribute, display, and perform the work) and **adapt** (make derivative works), in any medium or format, for **noncommercial** purposes, provided they follow the license terms. [1] 2. **Conditions** - **Attribution**: Must give appropriate credit, provide the license notice, and indicate if changes were made, without implying endorsement. - **NonCommercial**: No use “primarily intended for or directed toward commercial advantage or private monetary compensation.” [1] - **ShareAlike**: Derivatives must be distributed under the **same** or a **compatible** license. [1] 3. **Additional restrictions / revocation** Users may not impose legal terms or technological measures (e.g., DRM) that restrict others from exercising the license’s permissions. [1] Rights are automatically terminated if terms are violated, but may be reinstated if the violation is cured. (Termination/reinstatement language is elaborated more clearly in later 3.0+ licenses.) 4. **Disclaimers** The license is provided **“as-is”** with **no warranties**, and it does not affect moral rights, publicity/privacy rights, or fair dealing/fair use and other exceptions. [1][2] 5. **CC recommendations on newer versions** Creative Commons now recommends using **CC BY-NC-SA 4.0** for new works, describing 4.0 as the most up-to-date, internationally robust version.

The tutorial in question is "UNIX / Linux Tutorial for Beginners" by Michael Stonebank at the University of Surrey, commonly published under the **Creative Commons Attribution-NonCommercial-ShareAlike 2.0 (CC BY-NC-SA 2.0)** license [1][2]. **(1) Freedoms Granted:** Users are free to **share** (copy and redistribute the material in any medium or format) and **adapt** (remix, transform, and build upon the material). These freedoms apply for any purpose that is non-commercial [3]. **(2) Conditions Users Must Follow:** Three conditions apply. **Attribution (BY):** Users must give appropriate credit to the original author, provide a link to the license, and indicate if changes were made, in any reasonable manner but not suggesting endorsement. **NonCommercial (NC):** Users may not use the material for commercial purposes. **ShareAlike (SA):** If users remix, transform, or build upon the material, they must distribute their contributions under the same or a compatible license [3]. **(3) Additional Restrictions and Revocation:** Users may not apply legal terms or technological measures (such as DRM) that legally restrict others from doing anything the license permits. The licensor cannot revoke freedoms as long as the user follows the license terms [3]. **(4) Disclaimers Regarding Warranties and Other Rights:** The license does not guarantee warranties of any kind. It also does not address publicity, privacy, or moral rights. Patent and trademark rights are not granted. The licensor is not required to ensure all uses are free of third-party claims [3]. **(5) Recommendations Regarding Newer Versions:** Creative Commons officially recommends that users consider re-licensing under the **CC BY-NC-SA 4.0** version, as newer versions contain improved language, better international applicability, and enhanced legal clarity. A notice on the 2.0 deed directs users to the latest version [3][4]. ## References [1] Stonebank, M. "UNIX Tutorial for Beginners."
