Command-Query Separation (CQS) is a programming principle that states that a method should either be a command that performs an action or a query that returns data, but not both. This principle helps to maintain a clear distinction between actions that change the state of a system and those that retrieve information about the system's state. ### Key Aspects of CQS: 1. **Commands**: These are methods that perform operations that modify the state of an object or system.
Inversion of Control (IoC) is a design principle used in software development, particularly in the context of object-oriented programming and dependency injection. It refers to the inversion of the flow of control in a program. Instead of the application code controlling the flow and creating its dependencies, a framework or external component takes charge of this flow. ### Key Concepts of Inversion of Control: 1. **Control Flow**: In traditional programming, the application itself controls the flow of execution.
Armour-piercing ammunition is a type of ammunition designed specifically to penetrate armor or protective barriers, such as those found on vehicles or body armor. It typically achieves this through the use of a harder projectile material, a pointed design, or specialized shapes that reduce deformation upon impact.
In chemistry, "hydron" refers to the cation of hydrogen (H⁺). It represents a hydrogen atom that has lost its electron, resulting in a positively charged ion. This ion is fundamental in various chemical reactions, especially those involving acids and bases. In aqueous solutions, hydron interacts with water molecules to form hydronium ions (H₃O⁺), which are often what is actually present in solutions where H⁺ is discussed.
The Mel scale is a perceptual scale of pitches that approximates the way humans perceive sound frequencies. It is designed to reflect the non-linear way in which humans perceive differences in pitch. The scale is named after "melody" and is used primarily in the fields of audio processing and psychoacoustics. On the Mel scale, equal distances correspond to equal perceived differences in pitch.
Ambulatory assessment refers to a method of collecting data about a person's behavior, experiences, and physiological responses in real-world settings, rather than in a clinical or laboratory environment. This approach is often used in psychology, medicine, and health research to monitor changes over time, understand patterns, and assess the effectiveness of interventions.
Diffie–Hellman key exchange is a method that allows two parties to securely establish a shared secret key over an insecure communication channel. This shared key can then be used for symmetric encryption of messages. The key exchange process, developed by Whitfield Diffie and Martin Hellman in 1976, enables the parties to agree on a secret key without the need to exchange the key itself.
The "Human Microphone" is a participatory communication technique that emerged from grassroots movements, notably during the Occupy Wall Street protests starting in 2011. In situations where amplification devices like microphones are not available or permitted, participants use this technique to project their messages collectively. Here’s how it works: 1. **Repetition**: One speaker voices a message or a point, and the audience repeats it back in unison.
The Winchester Reading Prize is an annual literary award that recognizes and celebrates outstanding children's and young adult literature. Organized by the University of Winchester in the UK, the prize aims to encourage reading among young people and to promote authors who create engaging and enriching stories for children and young adults. Typically, the prize involves a shortlist of books selected by a panel of judges, which may include educators, librarians, and literature experts.
A gasoline pump, commonly referred to as a fuel pump or petrol pump, is a device used to dispense gasoline or petrol for vehicles. These pumps are typically found at gas stations and are an essential component of the infrastructure for fueling cars, motorcycles, and other vehicles that use gasoline as a power source. Here are some key features and functions of gasoline pumps: 1. **Dispensing Fuel**: Gasoline pumps have nozzles that allow customers to fill their vehicles with fuel.
"Pump" can refer to different things depending on the context. Here are a few common interpretations: 1. **Mechanical Device**: A pump is a mechanical device that moves fluids (liquids or gases) by mechanical action, often converted from electrical energy or another form of energy. Pumps are used in various applications, including water supply, heating and cooling systems, industrial processes, and more.
A sump pump is a device used to remove accumulated water from a sump basin, typically found in the basement of a home or building. Its primary function is to prevent flooding and manage water levels, particularly in areas prone to groundwater buildup or excessive moisture. Here are some key points about sump pumps: 1. **Function**: The main purpose of a sump pump is to keep the basement or crawl space dry by pumping out water that collects in the sump pit.

Intro to OurBigBook
. Source. We have two killer features:
- 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-calculusArticles 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.Figure 1. Screenshot of the "Derivative" topic page.
