# opuntiaOS > operating system **Wikidata**: [Q112181360](https://www.wikidata.org/wiki/Q112181360) **Source**: https://4ort.xyz/entity/opuntiaos ## Summary opuntiaOS is a hobbyist operating system designed to manage computer hardware resources. It is open-source software distributed under the permissive 2-clause BSD License, allowing users libre access to the original source code. The system is actively developed as a hobbyist project rather than for commercial use. ## Key Facts * **Classification:** opuntiaOS is an instance of a hobbyist operating system, open-source software, and a general operating system. * **License:** The software is distributed under the **2-clause BSD License**. * **Programming Languages:** The source code is written in **C** (Wikidata ID: Q15777) and **C++** (Wikidata ID: Q2407). * **Repository:** The source code is hosted publicly on GitHub at `https://github.com/opuntiaOS-Project/opuntiaOS`. * **Copyright Status:** The software is copyrighted. * **Development Nature:** It is explicitly developed as a hobby, distinguishing it from commercial or enterprise operating systems. ## FAQs ### Q: What type of software is opuntiaOS? A: opuntiaOS is a hobbyist operating system, which means it is software developed to manage computer hardware resources primarily for personal enjoyment and learning rather than commercial distribution. ### Q: Under what license is opuntiaOS released? A: opuntiaOS is released under the 2-clause BSD License. This is a permissive free software license that allows users to use, redistribute, and access the source code. ### Q: Where can the source code for opuntiaOS be found? A: The source code repository is located on GitHub at `https://github.com/opuntiaOS-Project/opuntiaOS`, where it is maintained by the opuntiaOS-Project group. ### Q: Which programming languages are used to write opuntiaOS? A: The operating system is written using the C and C++ programming languages. ## Why It Matters opuntiaOS serves as a distinct example of modern hobbyist operating system development, a field that demystifies how software manages computer hardware resources. Unlike proprietary systems that hide their inner workings, opuntiaOS provides libre access to its original source code, functioning as an educational resource for developers interested in low-level systems programming. Its existence highlights the enduring relevance of the open-source movement, where permissive licensing facilitates knowledge sharing. The project demonstrates the practical application of the C and C++ programming languages in creating complex system software from scratch. By utilizing the 2-clause BSD License, it ensures that the code remains free for anyone to use and redistribute in its current state, encouraging collaboration and modification within the software development community. opuntiaOS matters because it represents the grassroots spirit of computing: building functional, complex systems purely for the challenge and the utility of the community. ## Notable For * **Hobbyist Development:** It is a distinct example of an operating system developed explicitly as a hobby, showcasing individual or small-team contributions to OS architecture. * **Permissive Licensing:** The use of the 2-clause BSD License places it among software that prioritizes maximum freedom for users to redistribute and access code. * **Language Stack:** It utilizes the C and C++ programming languages, the industry standards for operating system kernels and system-level programming. * **Open Source Accessibility:** Unlike closed-source competitors, it provides full transparency into its hardware resource management algorithms via its public GitHub repository. ## Body ### Classification and Nature opuntiaOS is classified as an **operating system**, defined as software that manages computer hardware resources. Specifically, it falls under the subclass of **hobbyist operating systems**, indicating its development is driven by personal interest and the educational challenges of OS development rather than commercial market demands. As **open-source software**, it adheres to principles where anyone is free to use and redistribute the software in its current state. ### Technical Specifications The software is constructed using two primary programming languages: **C** and **C++**. These languages are frequently chosen for operating system development due to their ability to handle low-level memory management and hardware interaction efficiently. The copyright status of the software is listed as copyrighted, though it is distributed under an open license. ### Licensing and Distribution opuntiaOS is distributed under the **2-clause BSD License**. This license is known for being permissive, imposing minimal restrictions on how the software can be used, modified, and redistributed. It grants users libre access to the original source code. ### Source Code Availability The official source code repository is hosted on **GitHub**. The repository URL is `https://github.com/opuntiaOS-Project/opuntiaOS`. This public availability allows for inspection of the code and verification of its open-source status as of the last reference date in May 2022. ## References 1.
