hashslingrz
A hash slinger is a cook or food server in a cheap restaurant, especially one who is discourteous or inattentive to customers. However "hash" has a very different meaning on the Internet....

From Webopedia:

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, for these records, you would apply a formula to each name to produce a unique numeric value. So you might get something like:

  • 1345873 John smith
  • 3097905 Sarah Jones
  • 4060964 Roger Adams

Then to search for the record containing Sarah Jones, you just need to reapply the formula, which directly yields the index key to the record. This is much more efficient than searching through all the records till the matching record is found.
