Fork

As a piece of cutlery or kitchenware, a fork is a tool consisting of a handle with several narrow tines on one end. The fork is a primarily Western utensil, whereas in East Asia chopsticks have been more prevalent. Today, forks are increasingly available throughout East Asia. The usually metal utensil is used to lift food to the mouth or to hold ingredients in place while they are being cut by a knife. Food can be lifted either by spearing it on the tines, or by holding it on top of the tines, which are often curved slightly. A fork is shaped in the form of a trident but curved at the joint of the handle to the points.

Early history of forks is obscure, as a kitchen and dining utensil it's generally believed to have originated in the Roman Empire, as proved by archaeological evidences. The personal table fork most likely originated in the Eastern Roman, or Byzantine, Empire. Its use spread to what is now the Middle East during the first millennium CE and then spread into southern Europe during the second millennium. It did not become common in northern Europe until the 18th century and was not common in North America until the 19th century.

FORK-256

FORK-256 is a hash algorithm designed in response to security issues discovered in the earlier SHA-1 and MD5 algorithms. After substantial cryptanalysis, the algorithm is considered broken.

Background

In 2005, Xiaoyun Wang announced an order-collision attack on the government's hash standard SHA-1. The National Institute of Standards and Technology (NIST), the body responsible for setting cryptographic standards in the United States, concluded this was a practical attack (as previous estimates were order-) and began encouraging additional research into hash functions and their weaknesses. As part of this effort, NIST hosted two workshops where potential new algorithms, including FORK-256, were introduced and discussed. Rather than immediately select any of these algorithms, NIST conducted a public competition from 2007–2012 which ultimately resulted in the Keccak algorithm being selected for use as the SHA-3 standard.

Algorithm and Analysis

FORK-256 was introduced at the 2005 NIST Hash workshop and published the following year. FORK-256 uses 512-bit blocks and implements preset constants that change after each repetition. Each block is hashed into a 256-bit block through four branches that divides each 512 block into sixteen 32-bit words that are further encrypted and rearranged.

Generic top-level domain

Generic top-level domains (gTLDs) are one of the categories of top-level domains (TLDs) maintained by the Internet Assigned Numbers Authority (IANA) for use in the Domain Name System of the Internet. A top-level domain is the last label of every fully qualified domain name. They are called generic for historic reasons; initially, they were contrasted with country-specific TLDs in RFC 920.

The core group of generic top-level domains consists of the com, info, net, and org domains. In addition, the domains biz, name, and pro are also considered generic; however, these are designated as restricted, because registrations within them require proof of eligibility within the guidelines set for each.

Historically, the group of generic top-level domains included domains, created in the early development of the domain name system, that are now sponsored by designated agencies or organizations and are restricted to specific types of registrants. Thus, domains edu, gov, int, and mil are now considered sponsored top-level domains, much like the themed top-level domains (e.g., jobs). The entire group of domains that do not have a geographic or country designation (see country-code top-level domain) is still often referred to by the term generic TLDs.
