UNIX / Linux Tutorial for Beginners

Step 2

Deed

Question

A well-known early-2000s beginner UNIX/Linux tutorial created at a UK university is released under a Creative Commons license whose canonical URL ends with “/by-nc-sa/2.0/”. Identify this specific license version and comprehensively describe: (1) the freedoms it grants to users, (2) all core conditions imposed on reuse and redistribution, (3) any statements regarding the irrevocability of the granted freedoms, (4) the notice about how this version compares to newer 4.0 licenses, and (5) the disclaimers or limitations related to warranties and other rights. Your answer should synthesize information from the official license deed and associated explanatory notices.

Answer length: 200-300 words.

Depth checklist

Creative Commons Attribution-NonCommercial-ShareAlike 2.0 (BY-NC-SA 2.0) + Logic proof: identified via canonical URL ending '/by-nc-sa/2.0/' and its use by an early-2000s UNIX tutorial under a Creative Commons license

Width checklist

Correct identification of the freedoms: Share (copy and redistribute) and Adapt (remix, transform, build upon)
Explicit mention that freedoms are irrevocable provided 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 (no legal/technological barriers beyond license)
Statement that compliance is not required for public domain elements or applicable exceptions/limitations
Notice that this is an older version and that 4.0 licenses are more user-friendly and internationally robust, with recommendation to use 4.0 for new works
Disclaimer of warranties and note that other rights (e.g., privacy, publicity, moral rights) may limit use

Examiner rationale

The question uses contextual clues (an early-2000s UK UNIX tutorial and a canonical URL ending in '/by-nc-sa/2.0/') to require logical identification of the exact Creative Commons license (Deep reasoning). It then demands a comprehensive synthesis of freedoms, conditions, notices about version updates, and disclaimers drawn from multiple sections of the official license deed and explanatory pages (Wide aggregation).

Score 1 - 0

Both agents correctly identified the license as Creative Commons Attribution-NonCommercial-ShareAlike 2.0 (CC BY-NC-SA 2.0), satisfying the Deep Logic requirement. However, on Width/Completeness, Agent A covers all checklist elements: Share and Adapt freedoms, irrevocability, Attribution, NonCommercial, ShareAlike, No Additional Restrictions, the public domain/exceptions carve-out, the 4.0 upgrade notice, and warranty/other-rights disclaimers. Agent B omits two required elements: the explicit 'No Additional Restrictions' clause and the statement that compliance is not required for public domain material or statutory exceptions. While Agent B has slightly stronger visual formatting and contextual detail, Agent A is more complete and fully aligned with the ground-truth checklist. Therefore, Agent A provides the better overall answer.

Creative Commons Attribution-NonCommercial-ShareAlike 2.0 Generic (CC BY-NC-SA 2.0) is the license identified by the URL ending “/by-nc-sa/2.0/” [1]. 1. Freedoms granted • Share – copy, distribute and transmit the material in any medium or format. • Adapt – remix, transform and build upon the material. These freedoms apply for any purpose except those restricted below, and are available worldwide and for the duration of applicable copyright [1]. 2. Core conditions on reuse and redistribution • Attribution – you must give appropriate credit, provide a link to the license and indicate if changes were made, in a reasonable manner and without suggesting endorsement [1]. • Non-Commercial – you may not use the material for commercial purposes [1]. • ShareAlike – if you remix, transform or build upon the work, you must distribute your contributions under the same or a compatible license [1]. • No Additional Restrictions – you may not apply legal terms or technological measures that legally restrict others from doing anything the license permits [1]. 3. Irrevocability “The licensor cannot revoke these freedoms as long as you follow the license terms,” meaning the permissions are perpetual provided compliance is maintained [1]. 4. Notice comparing to 4.0 The deed notes that the 4.0 license suite is the most up-to-date version and encourages its use for new works, linking to the newer deeds for comparison [1]. 5. Disclaimers and limitations • No warranties are given; the material is provided “as-is” without representations or warranties of any kind [1]. • The license may not grant all permissions needed for your intended use—other rights such as publicity, privacy, or moral rights may still apply [1]. • Use of public-domain elements or statutory exceptions is not affected—you need not comply with the license for those parts [1]. ## References [1] Creative Commons. “Attribution-NonCommercial-ShareAlike 2.0 Generic (CC BY-NC-SA 2.0) Deed.” https://creativecommons.org/licenses/by-nc-sa/2.0/

The tutorial is **UNIX Tutorial for Beginners** created at the **University of Surrey**, and the specific license is **Creative Commons Attribution-NonCommercial-ShareAlike 2.0 Generic (CC BY-NC-SA 2.0)** [1][2]. **(1) Freedoms Granted:** The license allows users to **copy and redistribute** the material in any medium or format, and to **remix, transform, and build upon** the material. These freedoms apply as long as the license conditions are followed [3]. **(2) Core Conditions:** Three conditions govern reuse and redistribution. **Attribution (BY):** Users must give appropriate credit, provide a link to the license, and indicate if changes were made, in any reasonable manner but not suggesting licensor endorsement. **NonCommercial (NC):** The material may not be used for commercial purposes. **ShareAlike (SA):** If users remix, transform, or build upon the material, they must distribute contributions under the same license as the original [3]. **(3) Irrevocability:** The licensor cannot revoke the freedoms granted as long as the user follows the license terms. This means once the license is granted, it remains effective and cannot be withdrawn retroactively [3]. **(4) Comparison to Newer Licenses:** The deed includes a notice stating that this is a **human-readable summary** of a previous version and that users should consider licensing under **CC BY-NC-SA 4.0**, which provides improvements including international applicability, better clarity, and more robust legal infrastructure. The 4.0 version is described as the most current and recommended version [3][4]. **(5) Disclaimers and Limitations:** The license deed explicitly states it comes with **no warranties**. It also notes that the license may not grant all permissions necessary for intended use, as other rights such as **publicity, privacy, or moral rights** may limit usage. The deed is not itself a license but a simplified summary of the full legal code [3]. ## References [1] University of Surrey UNIX Tutorial for Beginners - http://www.ee.surrey.ac.uk/Teaching/Unix/ [2] Creative Commons License Reference on UNIX Tutorial - http://www.ee.surrey.ac.uk/Teaching/Unix/ [3] CC BY-NC-SA 2.0 Deed - https://creativecommons.org/licenses/by-nc-sa/2.0/ [4] Creative Commons License Versions - https://creativecommons.org/faq/#why-should-i-use-the-latest-version-of-the-creative-commons-licenses
