Caesar cipher. The action of a Caesar cipher is to replace each plaintext letter with a different one a fixed number of places down the alphabet. The cipher illustrated here uses a left shift of 3, so that (for example) each occurrence of E in the plaintext becomes B in the ciphertext. In cryptography, a Caesar cipher, also known as Caesar's ...
Literate Programming by Donald Knuth is the seminal book on literate programming.. Literate programming is a programming paradigm introduced in 1984 by Donald Knuth in which a computer program is given as an explanation of how it works in a natural language, such as English, interspersed (embedded) with snippets of macros and traditional source code, from which compilable source code can be ...
t. e. A translator or programming language processor is a computer program that converts the programming instructions written in human convenient form into machine language codes that the computers understand and process. It is a generic term that can refer to a compiler, assembler, or interpreter —anything that converts code from one ...
ROT13 ( Rotate13, " rotate by 13 places ", sometimes hyphenated ROT-13) is a simple letter substitution cipher that replaces a letter with the 13th letter after it in the Latin alphabet. ROT13 is a special case of the Caesar cipher which was developed in ancient Rome. Because there are 26 letters (2×13) in the basic Latin alphabet, ROT13 is ...
Shed Skin is an experimental restricted- Python (3.8+) to C++ programming language compiler. It can translate pure, but implicitly statically typed Python programs into optimized C++. It can generate stand-alone programs or extension modules that can be imported and used in larger Python programs. Shed Skin is an open source project with ...
v. t. e. A source-to-source translator, source-to-source compiler ( S2S compiler ), transcompiler, or transpiler[ 1][ 2][ 3] is a type of translator that takes the source code of a program written in a programming language as its input and produces an equivalent source code in the same or a different programming language.
Step-by-step process for the double columnar transposition cipher. In cryptography, a transposition cipher (also known as a permutation cipher) is a method of encryption which scrambles the positions of characters ( transposition) without changing the characters themselves. Transposition ciphers reorder units of plaintext (typically characters ...
Geek Code. Geek code example, which opens by stating that the user is a Geek of Technical Writing (GTW) who usually wears jeans and a t-shirt (d-@), is of average height and above-average weight (s:+), and is aged between 25 and 29 (a-). The Geek Code, developed in 1993, is a series of letters and symbols used by self-described "geeks" to ...
