Hash (food)
Hash is a dish consisting of chopped meat, potatoes, and fried onions. The name is derived from French language, French , meaning 'to chop'. Canned corned beef hash became especially popular in countries such as Britain and France during and after the Second World War as rationing limited the availability of fresh meat. Hash may be served for breakfast, lunch, or supper. When served for breakfast in the United States, hash may come with eggs, toast, hollandaise sauce, or baked beans. High-end restaurants offer sophisticated hash dishes on their menus. Modern preparations have been made with unconventional ingredients such as lamb, fish, venison, turkey, chicken, shrimp, or steak. United States "Hash" of many forms was part of the Standard American diet, 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.

Geohash
Geohash is a public domain geocode system invented in 2008 by Gustavo Niemeyer * * * which encodes a geographic location into a short string of letters and digits. Similar ideas were introduced by G.M. Morton in 1966. It is a hierarchical spatial data structure which subdivides space into buckets of grid shape, which is one of the many applications of what is known as a Z-order curve, and generally space-filling curves. Geohashes offer properties like arbitrary precision and the possibility of gradually removing characters from the end of the code to reduce its size (and gradually lose precision). Geohashing guarantees that the longer a shared prefix between two geohashes is, the spatially closer they are together. The reverse of this is not guaranteed, as two points can be very close but have a short or no shared prefix. History The core part of the Geohash algorithm and the first initiative to similar solution was documented in a report of G.M. Morton in 1966, "A Compu ...

Hash Browns
Hash browns, also spelled hashed browns and hashbrowns, are a popular American breakfast food consisting of finely julienned potatoes that have been fried until golden brown. Hash browns are a staple breakfast item at diners in North America, where they are often fried on a large, common cooktop or grill. Hash browns are a popular mass-produced product sold in refrigerated, frozen and dehydrated forms. Etymology The word ''hash'' is derived from the French word , which means 'to hack' or 'to chop'. In other words, hashed brown potatoes can be interpreted literally as "chopped and fried potatoes". History The following recipe for "brown hashed potatoes" appears in the 1835 edition of the ''Minnesota Farmers' Institute Annual'': Cited b''The Old Foodie'' whose article is cited b''TastingTable'' Hash browns first started appearing on breakfast menus in New York City in the 1890s. The name was gradually changed to "hash-brown potatoes". Preparation A chef may prepare h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hash House Harriers
The Hash House Harriers (HHH or H3) is an international group of non-competitive running social clubs. An event organized by a club is known as a Hash or Run, or a Hash Run. A common denominal verb for this activity is Hashing, with participants calling themselves Hashers. Members are referred to as Harriers or Harriettes based on gender or preference. The Hash is humorously known as ''A Drinking Club With A Running Problem,'' with the preferred beverage of consumption being beer. History Hashing originated in December 1938 in Kuala Lumpur, Selangor, then in the Federated Malay States (now Malaysia). A group of British people, British immigrants began meeting on Friday evenings, to run in a fashion patterned after the traditional British game of paper chase (game), hare and hounds, in which one or two "hare" runners scatter a trail of cut paper for the "hounds" to track. Apart from the excitement of chasing the hare and finding the trail, Harriers reaching the end of the trail ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zobrist Hashing
Zobrist hashing (also referred to as Zobrist keys or Zobrist signatures Bruce Moreland/ref>) is a hash function construction used in computer programs that play abstract board games, such as chess and Go, to implement transposition tables, a special kind of hash table that is indexed by a board position and used to avoid analyzing the same position more than once. Zobrist hashing is named for its inventor, Albert Lindsey Zobrist. It has also been applied as a method for recognizing substitutional alloy configurations in simulations of crystalline materials. Zobrist hashing is the first known instance of the generally useful underlying technique called tabulation hashing. Calculation of the hash value Zobrist hashing starts by randomly generating bitstrings for each possible element of a board game, i.e. for each combination of a piece and a position (in the game of chess, that's 6 pieces × 2 colors × 64 board positions, with a constant number of additional bitstrings for ca ...

Password Hash
In cryptography, a key derivation function (KDF) is a cryptographic algorithm that derives one or more secret keys from a secret value such as a master key, a password, or a passphrase using a pseudorandom function (which typically uses a cryptographic hash function or block cipher). KDFs can be used to stretch keys into longer keys or to obtain keys of a required format, such as converting a group element that is the result of a Diffie–Hellman key exchange into a symmetric key for use with AES. Keyed cryptographic hash functions are popular examples of pseudorandom functions used for key derivation. History The first deliberately slow (key stretching) password-based key derivation function was called "crypt" (or "crypt(3)" after its man page), and was invented by Robert Morris in 1978. It would encrypt a constant (zero), using the first 8 characters of the user's password as the key, by performing 25 iterations of a modified DES encryption algorithm (in which a 12-bit nu ...

Hash Chain
A hash chain is the successive application of a cryptographic hash function to a piece of data. In computer security, a hash chain is a method used to produce many one-time keys from a single key or password. For non-repudiation, a hash function can be applied successively to additional pieces of data in order to record the chronology of data's existence. Definition A hash chain is a successive application of a cryptographic hash function h to a string x. For example, h(h(h(h(x)))) gives a hash chain of length 4, often denoted h^(x) Applications Leslie LamportL. Lamport, “Password Authentication with Insecure Communication”, Communications of the ACM 24.11 (November 1981), pp 770-772/ref> suggested the use of hash chains as a password protection scheme in an insecure environment. A server which needs to provide authentication may store a hash chain rather than a plain text password and prevent theft of the password in transmission or theft from the server. For exa ...

Hash (Unix)
hash is a command on Unix and Unix-like operating systems that prints the location information for the commands found. The command has also been ported to the IBM i operating system. Syntax $ hash ame Description When the user gives a command, the shell searches for the command in the path specified in the PATH environmental variable and stores the location in the hash. This command can be used to search for the command given. The command is built into the shell. C shell implements this command in a different way. Options The following options are supported. ;name: Searches the PATH environmental variable for the name given Exit Status This command returns the following exit values: ;0: Successful completion ;1: An Error occurred Examples $ hash Print the hash table. $ hash cat Searches for command cat in the path specified by PATH environmental variable; if found, adds it to the hash.

Hashtag
A hashtag is a metadata tag operator that is prefaced by the hash symbol, ''#''. On social media, hashtags are used on microblogging and photo-sharing services–especially Twitter and Tumblr–as a form of user-generated tagging that enables cross-referencing of content by topic or theme. For example, a search within Instagram for the hashtag ''#bluesky'' returns all posts that have been tagged with that term. After the initial hash symbol, a hashtag may include letters, numerals or other punctuation. The use of hashtags was first proposed by American blogger and product consultant Chris Messina in a 2007 tweet. Messina made no attempt to patent the use because he felt that "they were born of the internet, and owned by no one". Hashtags became entrenched in the culture of Twitter and soon emerged across Instagram, Facebook, and YouTube. In June 2014, ''hashtag'' was added to the ''Oxford English Dictionary'' as "a word or phrase with the symbol ''#'' in front of it, used o ...

URI Fragment
In computer hypertext, a URI fragment is a string of characters that refers to a resource that is subordinate to another, primary resource. The primary resource is identified by a Uniform Resource Identifier (URI), and the fragment identifier points to the subordinate resource. The fragment identifier introduced by a hash mark # is the optional last part of a URL for a document. It is typically used to identify a portion of that document. The generic syntax is specified iRFC 3986 The hash mark separator in URIs is not part of the fragment identifier. Basics In URIs, a hash mark # introduces the optional fragment near the end of the URL. The generic RFC 3986 syntax for URIs also allows an optional query part introduced by a question mark ?. In URIs with a query and a fragment, the fragment follows the query. Query parts depend on the URI scheme and are evaluated by the server—e.g., http: supports queries unlike ftp:. Fragments depend on the document MIME type and are evaluate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
