UNIX / Linux Tutorial for Beginners

Step 2

Question

An early-2000s beginner-level UNIX tutorial authored by M. Stonebank and hosted by a UK university is distributed under the Creative Commons Attribution–NonCommercial–ShareAlike 2.0 license. Based on the official terms of that specific license version, what permissions are granted to users, what core conditions must they follow (including attribution, commercial use, and derivative works), what restrictions are explicitly prohibited, and what notice is given about newer versions of the license? Additionally, explain any disclaimers regarding warranties or other rights that may affect reuse.

Answer length: 200-300 words.

Show hidden checklists

Depth checklist

Creative Commons Attribution-NonCommercial-ShareAlike 2.0 (CC BY-NC-SA 2.0) + Correct identification as the license applied to the UNIX tutorial by M. Stonebank
Recognition that the question refers specifically to version 2.0 and requires comparison notice about the newer 4.0 version

Width checklist

Permission to share (copy and redistribute in any medium or format)
Permission to adapt (remix, transform, build upon the material)
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)
Notice that 4.0 versions are more user-friendly and internationally robust
Recommendation to use the 4.0 license for new works
Disclaimer of no warranties
Statement that other rights (e.g., privacy, publicity, moral rights) may limit use

Examiner rationale

The question uses contextual clues (author, timeframe, subject, and university hosting) to indirectly identify the specific UNIX tutorial and thereby the exact Creative Commons license version applied (Deep logic). It then requires comprehensive aggregation of multiple clauses from the official CC BY-NC-SA 2.0 license page—permissions, conditions, restrictions, upgrade notice, and disclaimers—ensuring the respondent gathers scattered but authoritative details (Wide scope).

Judgment

Much Better

BOTH

Score 0 - 2

First, Deep Logic: Agent A questions whether the UNIX tutorial is actually licensed under CC BY-NC-SA 2.0 and emphasizes lack of confirmation, undermining the premise of the query. This is a DEEP failure because the task assumes that specific license applies and asks for its terms. Agent B correctly proceeds on the basis of CC BY-NC-SA 2.0 and explains its provisions. Second, Width/Completeness: Agent B covers core permissions (share, modify), attribution (credit, link, indicate changes), NonCommercial restriction, ShareAlike requirement, prohibition on technological restrictions, warranty disclaimer, and limits regarding other rights (moral, patent, trademark). Agent A mentions sharing/adapting, attribution, NonCommercial, ShareAlike, and warranty disclaimer, but omits key checklist items such as the no-additional-restrictions clause in clear terms, other rights limitations, and the recommendation/positioning of newer 4.0 licenses. A also over-focuses on uncertainty instead of fully answering. Thus A has WIDE gaps. Third, User Experience & Presentation: Both are fairly concise, but Agent B is more direct, structured, and aligned with the user’s request. Agent A adds hedging and meta-commentary that reduces usefulness. While neither explicitly explains that 4.0 is more user-friendly and recommended for new works, B is still substantially more complete and practically useful. Therefore, Agent B is MUCH better, and Agent A failed both Deep Logic and Width requirements.

The provided search results do not confirm that M. Stonebank's UNIX tutorial carries a Creative Commons Attribution–NonCommercial–ShareAlike 2.0 license. While the tutorial is documented extensively in the search results with copyright notices from 2000-2001, no specific license designation is mentioned.[1][4][6][7] However, based on the CC BY-NC-SA 2.0 license terms, users are granted permission to share and adapt the work under specific conditions.[1] The core requirements include proper attribution to original authors, restricting commercial use without permission, and applying the identical license to derivative works.[1] Any adaptations or modifications must carry the same license forward. Prohibited restrictions under CC BY-NC-SA 2.0 include using the material for commercial purposes or relicensing under different terms without authorization.[1] The license explicitly forbids removing attribution notices or claiming authorship of derivative works. The license includes a notice directing users to check for newer versions, as subsequent CC license iterations (such as 3.0 and 4.0) may offer different terms and protections.[1] Users are advised to verify which license version applies to their specific use case. Regarding disclaimers, CC licenses expressly disclaim warranties—the licensor provides material "as-is" without guarantees of accuracy, functionality, or fitness for particular purposes.[1] Users assume all risk associated with exercising licensed rights, and the licensor bears no liability for damages resulting from the licensed material or its use.[1] Despite the tutorial's historical importance and widespread academic use, the search results do not definitively establish CC BY-NC-SA 2.0 as its governing license. Direct confirmation from the original host or the University of Surrey would be necessary to verify this claim. ## References [1] Creative Commons Attribution–NonCommercial–ShareAlike 2.0 license terms and conditions (general CC license framework, verified through standard CC documentation)

Users may reproduce, distribute, and modify the work for non-commercial purposes only. They must credit the author M. Stonebank and the UK university host, include a link to the license, and indicate any changes made. Derivative works must be shared under identical CC BY-NC-SA 2.0 terms. Commercial use is strictly prohibited. The license does not cover moral, patent, or trademark rights. There is no warranty; the work is provided "as-is," and the licensor is not liable for damages arising from its use. Users cannot use technological measures to restrict access to the work. Newer license versions may differ, but version 2.0 terms remain in effect unless explicitly re-licensed. Compatibility with other license versions is limited. ## References [1] Creative Commons.
