Hash

Hash, Hashes, Hash mark or Hashing may refer to:

Hash (food)

Hash is a dish consisting of diced or chopped meat, potatoes, and spices that are mixed together and then cooked either alone or with other ingredients such as onions. The name is derived from the French verb hacher (to chop).

Corned beef hash became especially popular in some countries including in Britain and France during and after World War II as rationing limited the availability of fresh meat.

In many locations, hash is served primarily as a breakfast food on restaurant menus and as home cuisine, often served with eggs and toast (or biscuits), and occasionally fried potatoes (hash browns, home fries, etc.). The dish may also use corned beef or roast beef.

Hash has recently made a comeback as more than just a dish for leftovers or breakfasts of last resort. High-end restaurants now offer sophisticated hashes and the first cookbook dedicated exclusively to a wide variety of hashes was self-published in 2012.

United States

The meat packing company Hormel claims that it introduced corned beef hash and roast beef hash to the U.S. as early as 1950, but "hash" of many forms was part of the American diet since at least the 18th century, as is attested by the availability of numerous recipes and the existence of many "hash houses" named after the dish. In the United States, September 27 is "National Corned Beef Hash Day."

Hash function

A hash function is any function that can be used to map data of arbitrary size to data of fixed size. The values returned by a hash function are called hash values, hash codes, hash sums, or simply hashes. One use is a data structure called a hash table, widely used in computer software for rapid data lookup. Hash functions accelerate table or database lookup by detecting duplicated records in a large file. An example is finding similar stretches in DNA sequences. They are also useful in cryptography. A cryptographic hash function allows one to easily verify that some input data maps to a given hash value, but if the input data is unknown, it is deliberately difficult to reconstruct it (or equivalent alternatives) by knowing the stored hash value. This is used for assuring integrity of transmitted data, and is the building block for HMACs, which provide message authentication.

Hash functions are related to (and often confused with) checksums, check digits, fingerprints, randomization functions, error-correcting codes, and ciphers. Although these concepts overlap to some extent, each has its own uses and requirements and is designed and optimized differently. The Hash Keeper database maintained by the American National Drug Intelligence Center, for instance, is more aptly described as a catalogue of file fingerprints than of hash values.

Kodu Game Lab

Kodu, originally named Boku, is a programming integrated development environment (IDE) by Microsoft's FUSE Labs. It runs on Xbox 360 and Microsoft Windows XP, Windows Vista, Windows 7, Windows 8 and Windows 10. It was released on the Xbox Live Marketplace on June 30, 2009. A Windows version is available to the general public for download from Microsoft's FUSE web portal.

Overview

Kodu is a visual programming tool which builds on ideas begun with Logo in the 1960s and other current projects such as AgentSheets, Squeak and Alice. It is designed to be accessible by anyone.

Kodu is available to download as an Xbox 360 Indie Game. There is also a PC version in an open beta which is available to anyone at their website.

Kodu is different from those other projects in several key ways:
