Renku is a collaborative data science platform that enables users to create, share, and publish reproducible research and data analyses. It is designed to facilitate teamwork among researchers, data scientists, and developers, allowing them to work together on projects in a transparent and organized manner. Renku supports the use of version control, similar to Git, which helps track changes in code and data over time. This makes it easier to manage project versions, collaborate effectively, and ensure that results are reproducible.
The term "Rubaʿi" refers to a specific form of poetry, particularly prominent in Persian literature, known for its quatrains (four-line stanzas). The word "rubaʿi" comes from the Arabic word "rubaʿ," which means "one-fourth," indicating the four lines of each poem.

FreeHAL is an open-source conversational AI project inspired by the HAL 9000 computer from Arthur C. Clarke's "2001: A Space Odyssey." It is designed to simulate human-like conversation and provide interactive dialogue capabilities. FreeHAL typically utilizes natural language processing (NLP) techniques to understand and respond to user input, making it suitable for applications such as chatbots, virtual assistants, and educational tools. The project allows developers to build and customize conversational agents, leveraging its basis in linguistic programming.
Derive is a computer algebra system (CAS) that was developed for symbolic mathematics and mathematical computation. Originally created by Soft Warehouse in the late 1980s, Derive allows users to perform algebraic operations such as simplification, differentiation, integration, factorization, and solving equations symbolically. Key features of Derive include: 1. **Symbolic Computation**: Users can work with algebraic expressions, polynomials, and symbolic equations rather than just numerical approximations.
The term "Artificial Intelligence Cold War" refers to the competitive landscape between nations, particularly between the United States and China, as they race to develop and dominate artificial intelligence technologies. This competition is characterized by significant investments in AI research and development, technological innovation, and the strategic implications these advancements hold for national security, economic power, and global influence.
"Mlecchita vikalpa" is a term from Indian philosophy, particularly in the context of yoga and meditation. It is often interpreted as the "option of the Mleccha" or "the choice of one who is uncivilized," referring to a state of being or a lifestyle considered to be outside the bounds of traditional or Vedic culture.
NSAKEY is a cryptographic key that is associated with the National Security Agency (NSA) in the United States. It is often discussed in the context of encryption, cybersecurity, and various forms of cryptographic communications. The term frequently arises in discussions about key management systems, secure communications, and potential vulnerabilities in encryption algorithms.
The Lighthill Report, officially titled "A Report of the Committee on the Education of the Gifted," was published in 1972 by a committee chaired by Sir Michael Lighthill in the United Kingdom. It primarily addressed the education of mathematically gifted students and highlighted the need for specialized educational programs and support tailored to their abilities. The report emphasized that gifted students often require different teaching methods and curricula to fully realize their potential.
A Lisp machine is a type of computer that is specifically designed to run the Lisp programming language efficiently. These machines were particularly popular in the 1980s and early 1990s, primarily in artificial intelligence research and development. Key characteristics of Lisp machines include: 1. **Hardware Optimized for Lisp**: Lisp machines often contained specialized hardware to speed up the execution of Lisp programs, including dedicated instruction sets and memory management tailored for the Lisp programming paradigm.
The MIT Computer Science and Artificial Intelligence Laboratory (CSAIL) is a research laboratory at the Massachusetts Institute of Technology (MIT) that focuses on computer science, artificial intelligence, and related fields. Founded in 2003 through the merger of the MIT Artificial Intelligence Laboratory and the MIT Laboratory for Computer Science, CSAIL is one of the leading research institutions in these domains.
STUDENT is a general-purpose computer program developed in the late 1970s and early 1980s for educational purposes, specifically to help students learn and practice programming concepts. It was designed to provide a simple environment for learning various programming languages and concepts. The features of STUDENT typically include: 1. **Interactive Learning**: The program allows students to write, run, and debug code in real-time, providing immediate feedback on their coding efforts.
The term "Code Talkers" primarily refers to Native American soldiers who used their languages as a means of secure communication during World War I and World War II. The most famous group of Code Talkers were the Navajo Code Talkers, who developed a complex code based on the Navajo language that was undecipherable to enemy forces. During World War II, their code was used extensively in the Pacific Theater, providing critical support for Allied operations and allowing for secure and rapid communication.
As of my last update in October 2023, Riverbank Laboratories is a private contract laboratory that specializes in providing comprehensive analytical testing services, primarily for the agricultural, food, and environmental sectors. The laboratory typically offers a range of services including chemical analysis, microbiological testing, and regulatory compliance support, helping clients ensure product safety and adherence to industry standards.
GRILL is a cryptographic algorithm that is part of the ongoing efforts to develop post-quantum cryptography. Specifically, it is designed to be resistant to potential attacks from quantum computers, which could threaten traditional cryptographic systems based on problems like integer factorization or discrete logarithms. GRILL is a key encapsulation mechanism (KEM) that combines various cryptographic techniques to ensure security.

Pinned article: Introduction to the OurBigBook Project

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.

  2. local editing: you can store all your personal knowledge base content locally in a plaintext markup format that can be edited locally and published either:
    This way you can be sure that even if OurBigBook.com were to go down one day (which we have no plans to do as it is quite cheap to host!), your content will still be perfectly readable as a static site.

    You can publish local OurBigBook lightweight markup files to either https://OurBigBook.com or as a static website
