Women in computer science refers to the contributions, achievements, and participation of women in the field of computer science and related areas, including programming, software development, artificial intelligence, data science, and more. Historically, women have played crucial roles in the development of computing technology, although their contributions have often been underrecognized.

The Ada Initiative was a nonprofit organization that aimed to promote the participation of women in open source and free software projects, as well as to support gender diversity in the technology sector more broadly. Founded in 2011 by Valerie Aurora and Mary Gardiner, the initiative sought to create resources and programs to help women become more involved in these fields and to advocate for a more inclusive culture within tech communities. The organization worked on various initiatives, including providing mentorship, organizing events, and producing educational materials.

AnitaB.org is a nonprofit organization dedicated to promoting the inclusion of women in technology and computing. Founded in memory of computer scientist Anita Borg, the organization seeks to empower women and encourage their participation in the tech industry through a variety of initiatives, conferences, and resources. One of its signature events is the Grace Hopper Celebration of Women in Computing, which is one of the largest gatherings of women technologists in the world. Additionally, AnitaB.

Computer Engineer Barbie is a doll and character from the Barbie line created by Mattel, designed to promote interest in technology and engineering among young girls. Introduced in 2010, Computer Engineer Barbie was portrayed as a tech-savvy role model who works in the field of computer engineering. The doll comes with accessories related to coding and technology, including a laptop and often themed clothing that reflects a modern, professional look.

Outreachy is a program that provides internships to underrepresented groups in the tech industry, including women, LGBTQ+ individuals, and people from marginalized communities. It is a part of the larger effort to increase diversity in open source and tech fields. The program typically involves participants working on real contributions to open source projects over a three-month period.

"Top Secret Rosies: The Female 'Computers' of WWII" is a documentary film that highlights the contributions of women mathematicians who worked as "computers" during World War II. The term "computer" at the time referred to individuals who performed complex calculations by hand, often using mathematical formulas to aid in various wartime initiatives, including ballistics and aircraft engineering. The film focuses on a group of women who were recruited to work for the U.S.

The term "Barbarian" can refer to several different concepts, depending on the context: 1. **Historical Context**: Originally, the term was used by the ancient Greeks to describe people who did not speak Greek and were considered uncivilized or primitive. The Romans later adopted this term, using it to refer to various groups that lived outside the boundaries of the Roman Empire, such as the Goths, Vandals, and Huns.

The Megarian philosophers were a group of philosophers in ancient Greece who emerged in the 4th century BCE in the city of Megara, near Athens. They are often associated with the philosophical school of thought known for its focus on logic, dialectics, and an exploration of the nature of reality and knowledge. The Megarian school is most closely linked to its founder, Euclid of Megara, who is known for his work in dialectic and for philosophical discussions that emphasized the use of reasoning.

Theophrastus was a prominent ancient Greek philosopher and naturalist who lived from around 371 to 287 BCE. He is often referred to as the "father of botany" due to his significant contributions to the study of plants and his systematic classification of them in his works, particularly in "Enquiry into Plants" (Historia Plantarum) and "On the Causes of Plants" (De Causis Plantarum).

Arbitrary inference is a cognitive distortion in which an individual draws a conclusion without any substantial evidence to support it. This type of reasoning often involves making assumptions based on limited information, leading to incorrect or unfounded beliefs. For instance, someone might assume that a friend is upset with them because they didn't respond to a text message quickly, even though there could be many other explanations for the delay.

An inference engine is a core component of an artificial intelligence (AI) system, particularly in knowledge-based systems or expert systems. It is responsible for applying logical rules to a set of knowledge or data to derive new information or make decisions. The inference engine performs reasoning by evaluating facts and rules in its knowledge base and using them to infer conclusions or actions.

Many-valued logic is a type of logic that extends the traditional binary notion of truth values, which is limited to "true" and "false." In many-valued logic, there can be more than two truth values, allowing for a richer interpretation of propositions. This approach can help to model uncertainty, vagueness, and degrees of truth that are often encountered in natural language, reasoning, and various fields such as mathematics, computer science, and philosophy.
