Unsourced material may be challenged and removed (July 2010) A hash function that maps names to integers from to 15. There is a collision between keys "John Smith" and "Sandra Dee". A hash function is any well-defined procedure or mathematical function that converts a large, possibly variable-sized amount of data into a small datum, usually a single integer that may serve as an index to an array (cf. associative array ). The values returned by a hash function are called hash values hash codes hash sums checksums or simply hashes Hash functions are mostly used to speed up table lookup or data comparison tasks—such as finding items in a database , detecting duplicated or similar records in a large file , finding similar stretches in DNA sequences, and so on. A hash function may map two or more keys to the same hash value. In many applications, it is desirable to minimize the occurrence of such collisions , which means that the hash function must map the keys to the hash values as evenly as possible. Depending on the application, other properties may be required as well. Although the idea was conceived in the 1950s

Who Are the Hash House Harriers? Hashing . . . it's a mixture of athleticism and sociability, hedonism and hard work, a refreshing escape from the nine-to-five dweebs you're stuck with five days a week. Hashing is an exhilaratingly fun combination of running, orienteering, and partying, where bands of harriers and harriettes chase hares on eight-to-ten kilometer-long trails through town, country, and desert, all in search of exercise, camaraderie, and good times. Hashing began in Kuala Lumpur, Malaysia, in 1938, when a group of British colonial officials and expatriates founded a running club called the Hash House Harriers. They named the group after their meeting place, the Selangor Club, nicknamed the "Hash House." Hash House Harrier runs were patterned after the traditional British paper chase. A "hare" was given a head start to blaze a trail, marking his devious way with shreds of paper, all the while pursued by a shouting pack of "harriers." Only the hare knew where he was going . . . the harriers followed his clues to stay on trail. Apart from the excitement of chasing the hare and solving the clues, reaching the end was its own reward . . . for there, thirsty harriers would find a tub of iced-down beer. Hashing died out during World War II (Japanese occupying forces being notoriously anti-fun) but picked up in the post-war years, spreading through the Far East, Australia, and New Zealand . . . then exploding in popularity in the mid-70s. Today there are thousands of Hash House Harrier clubs in all parts of the world, with newsletters, directories, and even regional and world hashing conventions.

As I said, though, that might be OK. You may be trying to crank this whole project out over the weekend and simply not have time for a better solution. That is how I wrote the caching layer for Audiogalaxy searches, and that turned out OK. The caching part, at least. But if had known about it at the time, I would have started with a simple version of consistent hashing. It isn’t that much more complicated to implement and it gives you a lot of flexibility down the road. The technical aspects of consistent hashing have been well explained in other places, and you’re crazy and negligent if you use this as your only reference. But, I’ll try to do my best. Consistent hashing is a technique that lets you smoothly handle these problems: Given a resource key and a list of servers, how do you find a primary, second, tertiary (and on down the line) server for the resource?

Webopedia.com Sign Up Sign In Search Term of the Day Recent Terms Did You Know? Quick Reference ... Home > hashing hashing Producing hash values for accessing data or for security . A hash value (or simply hash ), also called a message digest , is a number generated from a string of text. The hash is substantially smaller than the text itself, and is generated by a formula in such a way that it is extremely unlikely that some other text will produce the same hash value. Hashes play a role in security systems where they're used to ensure that transmitted messages have not been tampered with. The sender generates a hash of the message, encrypts it, and sends it with the message itself. The recipient then decrypts both the message and the hash, produces another hash from the received message, and compares the two hashes. If they're the same, there is a very high probability that the message was transmitted intact. Hashing is also a common method of accessing data records . Consider, for example, a list of names: John Smith Sarah Jones Roger Adams To create an index , called a hash table

Monday 1, November 2010 Home Tutorials Free Ebooks Free Scripts ... About Us Hashing The search time of each algorithm depend on the number n of elements of the collection S of the data. A searching technique called Hashing or Hash addressing which is essentially independent of the number n. Hashing is the transformation of a string of characters into a usually shorter fixed-length value or key that represents the original string. Hashing is used to index and retrieve items in a database because it is faster to find the item using the shorter hashed key than to find it using the original value. It is also used in many encryption algorithms. Hash Function: A Hash Function is a Unary Function that is used by Hashed Associative Containers: it maps its argument to a result of type . A Hash Function must be deterministic and stateless. That is, the return value must depend only on the argument, and equal arguments must yield equal results. Hash functions are mostly used in hash tables, to quickly locate a data record (for example, a dictionary definition given its search key (the headword). Specifically, the hash function is used to map the search key to the index of a slot in the table where the corresponding record is supposedly stored.
