Codes

A book cipher is a method of encryption and decryption that employs a physical book or text as the key. In this technique, secret messages are concealed by referencing specific words or passages from the book to encode and decode information. To encrypt a message, each word in the plaintext is replaced with a corresponding word or phrase found at a predetermined location within the chosen book.

Binary code is a system of representing information or data using only two symbols, typically 0 and 1. It is the basis of all digital systems, including computers. In binary code, each digit is called a bit (short for binary digit) and represents the presence or absence of a particular signal or state.

The Beale Cipher, also known as the Beale Papers, is a cryptographic mystery that revolves around a supposed hidden treasure buried in the United States. The Beale Cipher is attributed to Thomas J. Beale, who allegedly discovered the treasure in the early 19th century.

bc, for basic calculator (often referred to as bench calculator), is "an arbitrary-precision calculator language" with syntax similar to the C programming language.

bc is typically used as either a mathematical scripting language or as an interactive mathematical shell. bc. Developer(s)

bc is also a command for DOS. The bc command is an interactive process that provides arbitrary-precision arithmetic. The bc command first reads any input files specified by the File parameter and then reads the standard input.

/bach/

adj. 1. Non-interactive. Hackers use this somewhat more loosely than the traditional technical definitions justify; in particular, switches on a normally interactive program that prepare it to receive non-interactive command input are often referred to as 'batch mode' switches. A 'batch file' is a series of instructions written to be handed to an interactive program running in batch mode.

2. Performance of dreary tasks all at one sitting.

The Language of Machine Instruction

Assembly language, often referred to as Assembly is a low-level programming language that bridges the gap between human-readable code and machine-executable instructions. Its roots can be traced back to the early days of computing when programmers needed a more efficient way to communicate with the hardware of early computers. As hardware technologies evolved, so did Assembly, becoming a foundational language for programming and system development.

ASCII (American Standard Code for Information Interchange) is a widely used character encoding standard that represents text in computers and other devices. It was developed in the early 1960s by a committee led by Robert W. Bemer to establish a consistent and universal character set for electronic communication and data interchange.

/ada/

n. A Pascal-descended language that has been made mandatory for Department of Defense software projects by the Pentagon. Hackers are nearly unanimous in observing that, technically, it is precisely what one might expect given that kind of endorsement by fiat; designed by committee, crockish, difficult to use, and overall a disastrous, multi-billion-dollar boondoggle (one common description is "The PL/I of the 1980s").
