Since the transmitted message must have satisfied the code constraints, the message can be represented by writing the received message on the top of the factor graph. In this example, the first bit cannot yet be recovered, because all of the constraints connected to it have more than one unknown bit.
A cyclic redundancy check (CRC) is an error-detecting code commonly used in digital networks and storage devices to detect accidental changes to digital data. [1][2] Blocks of data entering these systems get a short check value attached, based on the remainder of a polynomial division of their contents. On retrieval, the calculation is repeated ...
ping – a computer network tool used to detect hosts. The author of ping, Mike Muuss, named it after the pulses of sound made by a sonar called a "ping". Later Dave Mills provided the backronym " P acket I nter n et G roper". Python – an interpreted scripting programming language.
The shebang is actually a human-readable instance of a magic number in the executable file, the magic byte string being 0x23 0x21, the two-character encoding in ASCII of #!. This magic number is detected by the " exec " family of functions, which determine whether a file is a script or an executable binary.
These are the items Americans lose most. Perhaps unsurprisingly, the most commonly lost items were also among the most ubiquitous and important: phones and keys. Most people don't leave home ...
When an item is to be added to the table, the hash code may index an empty slot (also called a bucket), in which case the item is added to the table there. If the hash code indexes a full slot, then some kind of collision resolution is required: the new item may be omitted (not added to the table), or replace the old item, or be added to the ...

Syntax definition. Parse tree of Python code with inset tokenization. The syntax of textual programming languages is usually defined using a combination of regular expressions (for lexical structure) and Backus–Naur form (a metalanguage for grammatical structure) to inductively specify syntactic categories (nonterminal) and terminal symbols.
