Dogs have the ability to make sounds that may sound like words, but they do not have the ability to talk or converse.
Cryptographic hash functions
A cryptographic hash function is a hash function that takes an arbitrary block of data and returns a fixed-size bit string, the cryptographic hash value, such that any (accidental or intentional) change to the data will (with very high probability) change the hash value. The data to be encoded are often called the message, and the hash value is sometimes called the message digest or simply digest.
The ideal cryptographic hash function has four main properties:
In computer science, a search algorithm is an algorithm for finding an item with specified properties among a collection of items. The items may be stored individually as records in a database; or may be elements of a search space defined by a mathematical formula or procedure, such as the roots of an equation with integer variables; or a combination of the two, such as the Hamiltonian circuits of a graph.
Algorithms for searching virtual spaces are used in constraint satisfaction problem, where the goal is to find a set of value assignments to certain variables that will satisfy specific mathematical equations and inequations. They are also used when the goal is to find a variable assignment that will maximize or minimize a certain function of those variables. Algorithms for these problems include the basic brute-force search (also called "naïve" or "uninformed" search), and a variety of heuristics that try to exploit partial knowledge about structure of the space, such as linear relaxation, constraint generation, and constraint propagation.
A hash function is any algorithm that maps data of a variable length to data of a fixed length. The values returned by a hash function are called hash values, hash codes, hash sums, checksums or simply hashes.
In computer science, a hash list is typically a list of hashes of the data blocks in a file or set of files. Lists of hashes are used for many different purposes, such as fast table lookup (hash tables) and distributed databases (distributed hash tables). This article covers hash lists that are used to guarantee data integrity.
A hash list is an extension of the old concept of hashing an item (for instance, a file). A hash list is usually sufficient for most needs, but a more advanced form of the concept is a hash tree.
Food and drink
Hash browns or hashed browns are a simple potato preparation in which potato pieces are pan-fried after being shredded, julienned, diced, or riced. In some cultures, hash browns or hashed browns can refer to any of these preparations, while in others it may refer to one specific preparation. In parts of the UK, hash browns can mean fried left over mashed potato. Hash browns are a staple breakfast food at diners in North America, where they are often fried on a large common cooktop or grill.
In some parts of the United States, hash browns strictly refer to shredded or riced pan-fried potatoes and are considered a breakfast food, while potatoes diced or cubed and pan-fried are also a side dish called country fried potatoes or home fries (though many variations of home fries are par-cooked before frying). Some recipes add diced or chopped onions.
Error detection and correction
Food is any substance consumed to provide nutritional support for the body. It is usually of plant or animal origin, and contains essential nutrients, such as carbohydrates, fats, proteins, vitamins, or minerals. The substance is ingested by an organism and assimilated by the organism's cells in an effort to produce energy, maintain life, or stimulate growth.
Historically, people secured food through two methods: hunting and gathering, and agriculture. Today, most of the food energy consumed by the world population is supplied by the food industry.
In information theory and coding theory with applications in computer science and telecommunication, error detection and correction or error control are techniques that enable reliable delivery of digital data over unreliable communication channels. Many communication channels are subject to channel noise, and thus errors may be introduced during transmission from the source to a receiver. Error detection techniques allow detecting such errors, while error correction enables reconstruction of the original data.
The general definitions of the terms are as follows:
Breakfast is the first meal taken after rising from a night's sleep, most often eaten in the early morning before undertaking the day's work. Among English speakers, "breakfast" can be used to refer to this meal or to refer to a meal composed of traditional breakfast foods (such as eggs, oatmeal and sausage) served at any time of day. The word literally refers to breaking the fasting period of the prior night.
Breakfast foods vary widely from place to place, but often include a carbohydrate such as grains or cereals, fruit and/or vegetables, a protein food such as eggs, meat or fish, and a beverage such as tea, coffee, milk or fruit juice. Coffee, milk, tea, juice, breakfast cereals, pancakes, sausages, French toast, bacon, sweet breads, fresh fruit, vegetables, eggs, mushrooms, baked beans, muffins, crumpets and toast with butter or margarine and/or jam or marmalade are common examples of breakfast foods, though a large range of preparations and ingredients are associated with breakfast globally.
In journalism, a human interest story is a feature story that discusses a person or people in an emotional way. It presents people and their problems, concerns, or achievements in a way that brings about interest, sympathy or motivation in the reader or viewer.
Human interest stories may be "the story behind the story" about an event, organization, or otherwise faceless historical happening, such as about the life of an individual soldier during wartime, an interview with a survivor of a natural disaster, a random act of kindness or profile of someone known for a career achievement.
