Answers to Questions (FAQ)
How to write in Deadfish?
The deadfish is a programming language simplified to the extreme using a single memory cell (initialized at 0) and 4 functions:
| i | increments the memory cell (+1) |
| d | decrement the memory cell (-1) |
| s | square (^2) the value of the memory cell |
| o | displays the value of the memory cell |
Example: To code the number 8, it is possible to write iiiiiiiio (8 increments and output) or iisiiiio (2 increments = 2, then squared = 4, 4 increment = 8 and output) or also iisdo (3 increments = 3, then squared = 9, 1 decrement = 8 and output)
How to decrypt a Deadfish code?
Deadfish is not a cipher but a programming language, so use an interpreter to launch the program and display the result.
Example: iiiso corresponds to 3 increments i (+1+1+1=3), then a squaring s (3^2=9) and display of the result o, ie the number 9
The program can only display numbers, but those can use a given nomenclature (ASCII code, A1Z26, etc.) to get a plain text.
How to recognize a Deadfish code?
Deadfish has only 4 distinct letters, by default i, s, d and o in lower case.
The amount of i and d is generally greater than the amount of o and s.
There are as many o as numbers (or characters) in the output values from the program.
What are the variants of Deadfish?
The XKCD site has proposed a variant with its own letters replacing i with x, s with' k and o with c ( d rest).
Due to its design and level of abstraction, Deadfish resembles the Brainfuck family of languages.
Who did create Deadfish?
Deadfish have been created by Jonathan Todd Skinne
