UNIX / Linux Tutorial for Beginners

Step 2

Deed

Question

An early-2000s beginner-oriented UNIX/Linux tutorial created at a UK university was released under a Creative Commons license that is now considered an older version. Identify the exact Creative Commons license version used for that tutorial and explain in detail: (1) the freedoms it grants to users, (2) the specific conditions users must follow, (3) any statements about revocability of those freedoms, (4) disclaimers or limitations of liability and rights, and (5) what newer license version is recommended instead and why.

Answer length: 200-300 words.

Depth checklist

Creative Commons Attribution-NonCommercial-ShareAlike 2.0 + Correctly linked to an early-2000s UNIX/Linux beginner tutorial released under a CC license
Attribution-NonCommercial-ShareAlike 4.0 International + Correctly identified as the recommended newer, more internationally robust replacement

Width checklist

Correct identification of the Attribution-NonCommercial-ShareAlike 2.0 license
Explanation of freedoms: share (copy and redistribute) and adapt (remix, transform, build upon)
Statement that freedoms are irrevocable provided license terms are followed
Conditions: Attribution requirement (credit, link to license, indicate changes)
Conditions: NonCommercial restriction
Conditions: ShareAlike requirement
Mention of prohibition on adding additional legal/technological restrictions
Acknowledgment of public domain/exception limitations
Disclaimer of no warranties and possible other rights (e.g., privacy, publicity, moral rights)
Identification of recommended Attribution-NonCommercial-ShareAlike 4.0 International version
Explanation that 4.0 is more user-friendly and internationally robust

Examiner rationale

The question uses contextual clues (early-2000s UNIX/Linux beginner tutorial from a UK university under a Creative Commons license) to indirectly point to the specific CC BY-NC-SA 2.0 license without naming it (Deep reasoning). It then requires aggregating multiple categories of information from the license deed and legal summary—freedoms, conditions, revocability, disclaimers, and upgrade recommendations—ensuring broad retrieval across the license’s provisions (Wide aggregation).

Judgment

Better

NONE

Score 1 - 0

First, Deep Logic: Both agents correctly identified the University of Surrey UNIX/Linux tutorial and the Creative Commons Attribution-NonCommercial-ShareAlike 2.0 UK: England & Wales license, and both correctly named CC BY-NC-SA 4.0 International as the recommended newer version. So both pass the core entity check. Second, Width/Completeness: Both explain the core freedoms (share/adapt), attribution, noncommercial, share-alike, irrevocability (conditional on compliance), disclaimers of warranty, and mention other rights (privacy/moral rights). Agent B explicitly mentions fair dealing exceptions; Agent A more thoroughly explains improvements in 4.0 (international robustness, database rights, cure period, compatibility). Both miss the explicit “no additional legal/technological restrictions” clause, so neither is perfect. Coverage is slightly richer and more detailed in Agent A. Third, User Experience & Presentation: Agent A presents a cleaner, more structured explanation and clearer breakdown of freedoms, conditions, and upgrade rationale. Agent B includes visible browser command artifacts (e.g., "to=browser.search"), which negatively impact readability and polish. While both are informative, Agent A provides a more professional, search-engine-like experience. Therefore, Agent A wins on overall completeness and presentation quality, though both are factually strong.

The UNIX/Linux tutorial you're referring to is likely "Introduction to UNIX and Linux" created at the University of Surrey, UK, which was released under Creative Commons Attribution-NonCommercial-ShareAlike 2.0 UK: England & Wales License (CC BY-NC-SA 2.0 UK) [1][2]. This CC BY-NC-SA 2.0 UK license grants users four key freedoms: (1) share - copy and redistribute the material in any medium or format; (2) adapt - remix, transform, and build upon the material. The license conditions require: Attribution - users must give appropriate credit, provide a link to the license, and indicate if changes were made; NonCommercial - users cannot use the material for commercial purposes; ShareAlike - if users remix, transform, or build upon the material, they must distribute their contributions under the same license as the original [3]. The license explicitly states these freedoms cannot be revoked by the licensor as long as users follow the license terms. Once granted, these permissions remain valid even if the licensor changes their mind later [3][4]. The license includes standard disclaimers stating the material is provided "as-is" without warranties. The licensor is not liable for any damages arising from use of the work. No trademark or patent rights are granted under this license [3]. The recommended upgrade is CC BY-NC-SA 4.0 International, which offers several improvements: better international portability without jurisdiction-specific versions, clearer attribution requirements, improved compatibility with other licenses, explicit database rights coverage, and a 30-day cure period for license violations. The 4.0 version also includes improved readability and addresses modern digital sharing scenarios [4][5]. ## References [1] University of Surrey UNIX Tutorial - http://www.ee.surrey.ac.uk/Teaching/Unix/ [2] Archive.org UNIX Tutorial Mirror - https://web.archive.org/web/20040603062715/http://www.ee.surrey.ac.uk/Teaching/Unix/ [3] Creative Commons BY-NC-SA 2.0 UK License - https://creativecommons.org/licenses/by-nc-sa/2.0/uk/ [4] Creative Commons License Versions - https://creativecommons.org/licenses/ [5] Creative Commons 4.0 Improvements - https://creativecommons.org/version4/

That license grants users the freedom to **copy, distribute, display, and perform** the work, and to **make derivative works**, provided the license terms are respected [2]. The required conditions are threefold: **Attribution**—users must give the credit specified by the author/licensor; **NonCommercial**—the work may not be used for commercial purposes; and **ShareAlike**—if users adapt or build on it, they must distribute the result only under the same or a similar license [2]. The license deed also states that, for any reuse or distribution, users must make the license terms clear to others, and that any of these conditions can be waived if the copyright holder permits it [2]. On revocability, Creative Commons explains that licensors **cannot revoke these freedoms as long as users follow the license terms** [3]. The older deed also includes important caveats: **fair dealing/fair use and other statutory exceptions are unaffected**, and **other rights** such as privacy, publicity, or moral rights may still limit reuse [2]. Creative Commons additionally provides the license **“as-is,” without warranties**, and disclaims liability to the extent possible [4]. Creative Commons now marks this as an **older license** and recommends using **version 4.0** instead, because 4.0 is the **most up-to-date** and is recommended for new works due to improved international robustness and clarity [2][5]. ## References 1.
