A Request for Comments (RFC), in the context of Internet governance, is a type of publication from the Internet Engineering Task Force (IETF) and the Internet Society (ISOC), usually describing methods, behaviors, research, or innovations applicable to the working of the Internet and Internet-connected systems. Almost every April Fools' Day (1 April) since 1989, the Internet RFC Editor has published one or more humorous Request for Comments (RFC) documents, following in the path blazed by the June 1973 RFC called ARPAWOCKY, a parody of Lewis Carroll's nonsense poem "Jabberwocky". The following list also includes humorous RFCs published on other dates. List of April Fools' Day RFCs * :: A parody of the TCP/IP documentation style. For a long time it was specially marked in the RFC index with "note date of issue". * * :: Updated by RFC 2549 in 1999; see below.

Request For Comments
A Request for Comments (RFC) is a publication in a series from the principal technical development and standards-setting bodies for the Internet, most prominently the Internet Engineering Task Force (IETF). An RFC is authored by individuals or groups of engineers and computer scientists in the form of a memorandum describing methods, behaviors, research, or innovations applicable to the working of the Internet and Internet-connected systems. It is submitted either for peer review or to convey new concepts, information, or, occasionally, engineering humor. The IETF adopts some of the proposals published as RFCs as Internet Standards. However, many RFCs are informational or experimental in nature and are not standards. The RFC system was invented by Steve Crocker in 1969 to help record unofficial notes on the development of ARPANET. RFCs have since become official documents of Internet specifications, communications protocols, procedures, and events. According to Crocker, the docu ...

Infinite Monkey Theorem
The infinite monkey theorem states that a monkey hitting keys independently and at randomness, random on a typewriter keyboard for an infinity, infinite amount of time will almost surely type any given text, including the complete works of William Shakespeare. More precisely, under the assumption of independence and randomness of each keystroke, the monkey would almost surely type every possible finite text an infinite number of times. The theorem can be generalized to state that any infinite sequence of independent events whose probabilities are uniformly bounded below by a positive number will almost surely have infinitely many occurrences. In this context, "almost surely" is a mathematical term meaning the event happens with probability 1, and the "monkey" is not an actual monkey, but a metaphor for an Abstract and concrete, abstract device that produces an endless random sequence of letters and symbols. Variants of the theorem include multiple and even infinitely many indepen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hide-and-seek
Hide-and-seek (sometimes known as hide-and-go-seek) is a children's game in which at least two players (usually at least three) conceal themselves in a set environment, to be found by one or more seekers. The game is played by one chosen player (designated as being "it") counting to a predetermined number with eyes closed while the other players hide. After reaching this number, the player who is "it" calls "Ready or not, here I come!" or "Coming, ready or not!" and then attempts to locate all concealed players. The game can end in one of several ways. The most common way of ending is the player chosen as "it" locates all players; the player found first is the loser and is chosen to be "it" in the next game. The player found last is the winner. Another common variation has the seeker counting at "home base"; the hiders can either remain hidden or they can come out of hiding to race to home base; once they touch it, they are "safe" and cannot be tagged. The game is an example o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Service Discovery
Service discovery is the process of automatically detecting devices and services on a computer network. It aims to reduce the manual configuration effort required from users and administrators. A service discovery protocol (SDP) is a network protocol that helps accomplish service discovery. Service discovery requires a common language to allow software agents to make use of one another's services without the need for continuous user intervention. Protocols There are many service discovery protocols, including: * Bluetooth Service Discovery Protocol (SDP) * Bonjour, e.g., Apple AirPrint * DNS Service Discovery (DNS-SD), a component of zero-configuration networking * DNS, as used for example in Kubernetes * Dynamic Host Configuration Protocol (DHCP); its classification as a service discovery protocol is controversial * Internet Storage Name Service (iSNS) * Jini for Java objects. * Lightweight Service Discovery (LSD), for mobile ad hoc networks * Link Layer Discovery P ...

RTP Control Protocol
The RTP Control Protocol (RTCP) is a binary-encoded out-of-band signaling protocol that functions alongside the Real-time Transport Protocol (RTP). RTCP provides statistics and control information for an RTP session. It partners with RTP in the delivery and packaging of multimedia data but does not transport any media data itself. The primary function of RTCP is to provide feedback on the quality of service (QoS) in media distribution by periodically sending statistics information such as transmitted octet and packet counts, packet loss, packet delay variation, and round-trip delay time to participants in a streaming multimedia session. An application may use this information to control quality of service parameters, perhaps by limiting flow, or using a different codec. Protocol functions Typically RTP will be sent on an even-numbered UDP port, with RTCP messages being sent over the next higher odd-numbered port. RTCP itself does not provide any flow encryption or authen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Real-time Transport Protocol
The Real-time Transport Protocol (RTP) is a network protocol for delivering audio and video over IP networks. RTP is used in communication and entertainment systems that involve streaming media, such as telephony, video teleconference applications including WebRTC, television services and web-based push-to-talk features. RTP typically runs over User Datagram Protocol (UDP). RTP is used in conjunction with the RTP Control Protocol (RTCP). While RTP carries the media streams (e.g., audio and video), RTCP is used to monitor transmission statistics and quality of service (QoS) and aids synchronization of multiple streams. RTP is one of the technical foundations of voice over IP and in this context is often used in conjunction with a signaling protocol such as the Session Initiation Protocol (SIP) which establishes connections across the network. RTP was developed by the Audio-Video Transport Working Group of the Internet Engineering Task Force (IETF) and first published i ...

MPEG-2
MPEG-2 (a.k.a. H.222/H.262 as was defined by the ITU) is a standard for "the generic coding of moving pictures and associated audio information". It describes a combination of lossy video compression and lossy audio data compression methods, which permit storage and transmission of movies using currently available storage media and transmission bandwidth. While MPEG-2 is not as efficient as newer standards such as H.264/AVC and H.265/HEVC, backwards compatibility with existing hardware and software means it is still widely used, for example in over-the-air digital television broadcasting and in the DVD-Video standard. Main characteristics MPEG-2 is widely used as the format of digital television signals that are broadcast by terrestrial (over-the-air), cable, and direct broadcast satellite TV systems. It also specifies the format of movies and other programs that are distributed on DVD and similar discs. TV stations, TV receivers, DVD players, and other equipment are ...

Facebook
Facebook is a social media and social networking service owned by the American technology conglomerate Meta Platforms, Meta. Created in 2004 by Mark Zuckerberg with four other Harvard College students and roommates, Eduardo Saverin, Andrew McCollum, Dustin Moskovitz, and Chris Hughes, its name derives from the face book directories often given to American university students. Membership was initially limited to Harvard students, gradually expanding to other North American universities. Since 2006, Facebook allows everyone to register from 13 years old, except in the case of a handful of nations, where the age requirement is 14 years. , Facebook claimed almost 3.07 billion monthly active users worldwide. , Facebook ranked as the List of most-visited websites, third-most-visited website in the world, with 23% of its traffic coming from the United States. It was the most downloaded mobile app of the 2010s. Facebook can be accessed from devices with Internet connectivit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bert (Sesame Street)
Bert and Ernie are two Muppet characters who appear together in numerous skits on the PBS/HBO children's television show ''Sesame Street''. Ernie acts the role of the naïve and exuberant troublemaker, while Bert is the world-weary foil. Originated by Frank Oz and Jim Henson, the characters are currently performed by puppeteers Eric Jacobson and Peter Linz. History Bert and Ernie were built by Don Sahlin from a simple design scribbled by Jim Henson, creator of ''The Muppets''. Initially, Henson performed Bert, and Oz performed Ernie. After just one day of rehearsal, they switched characters. The original idea was to show that even though two people can have totally different characteristics, they can still be good friends. According to writer Jon Stone, the relationship between Bert and Ernie reflected the real-life friendship between Oz and Henson. Although their names are commonly believed to have been drawn from those of two minor characters in the Frank Capra film '' ...

Internet Protocol
The Internet Protocol (IP) is the network layer communications protocol in the Internet protocol suite for relaying datagrams across network boundaries. Its routing function enables internetworking, and essentially establishes the Internet. IP has the task of delivering Packet (information technology), packets from the source Host (network), host to the destination host solely based on the IP addresses in the packet Header (computing), headers. For this purpose, IP defines packet structures that encapsulation (networking), encapsulate the data to be delivered. It also defines addressing methods that are used to label the datagram with source and destination information. IP was the connectionless datagram service in the original ''Transmission Control Program'' introduced by Vint Cerf and Bob Kahn in 1974, which was complemented by a connection-oriented service that became the basis for the Transmission Control Protocol (TCP). The Internet protocol suite is therefore often referre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PDP-10
Digital Equipment Corporation (DEC)'s PDP-10, later marketed as the DECsystem-10, is a mainframe computer family manufactured beginning in 1966 and discontinued in 1983. 1970s models and beyond were marketed under the DECsystem-10 name, especially as the TOPS-10 operating system became widely used. The PDP-10's architecture is almost identical to that of DEC's earlier PDP-6, sharing the same 36-bit Word (computer architecture), word length and slightly extending the instruction set. The main difference was a greatly improved hardware implementation. Some aspects of the instruction set are unusual, most notably the ''byte'' instructions, which operate on bit fields of any size from 1 to 36 bits inclusive, according to the general definition of a byte as ''a contiguous sequence of a fixed number of bits''. The PDP-10 was found in many university computing facilities and research labs during the 1970s, the most notable being Harvard University's Aiken Computation Laboratory, Mass ...
