element .io. Element (formerly Riot and Vector[ 11]) is a free and open-source software instant messaging client implementing the Matrix protocol. [ 12] Element supports end-to-end encryption, [ 13] private and public groups, sharing of files between users, voice and video calls, and other collaborative features with help of bots and widgets.
Traditional Reed–Muller codes are binary codes, which means that messages and codewords are binary strings. When r and m are integers with 0 ≤ r ≤ m, the Reed–Muller code with parameters r and m is denoted as RM ( r , m ). When asked to encode a message consisting of k bits, where holds, the RM ( r , m) code produces a codeword ...
This is a list of TCP and UDP port numbers used by protocols for operation of network applications. The Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP) only need one port for duplex , bidirectional traffic.
YMSG ( Yahoo! Messenger ) ^ a b One-to-many / many-to-many communications primarily comprise presence information, publish/subscribe and groupchat distribution. Some technologies have the ability to distribute data by multicast, avoiding bottlenecks on the sending side caused by the number of recipients.
A generator matrix for a linear [,,]-code has format , where n is the length of a codeword, k is the number of information bits (the dimension of C as a vector subspace), d is the minimum distance of the code, and q is size of the finite field, that is, the number of symbols in the alphabet (thus, q = 2 indicates a binary code, etc.).
Matrix (sometimes stylized as [matrix]) is an open standard and communication protocol for real-time communication. [2] It aims to make real-time communication work seamlessly between different service providers, in the way that standard Simple Mail Transfer Protocol email currently does for store-and-forward email service, by allowing users with accounts at one communications service provider ...
A UPC-A barcode. A barcode or bar code is a method of representing data in a visual, machine-readable form. Initially, barcodes represented data by varying the widths, spacings and sizes of parallel lines. These barcodes, now commonly referred to as linear or one-dimensional (1D), can be scanned by special optical scanners, called barcode ...
Small-bias sample space. In theoretical computer science, a small-bias sample space (also known as -biased sample space, -biased generator, or small-bias probability space) is a probability distribution that fools parity functions . In other words, no parity function can distinguish between a small-bias sample space and the uniform distribution ...
