Takuzu, also known as Binairo, is a logic puzzle involving placement of two symbols, often 1s and 0s, on a rectangular grid. The objective is to fill the grid with 1s and 0s, where there is an equal number of 1s and 0s in each row and column and no more than two of either number adjacent to each other. Additionally, there can be no identical ...
Binary translation. In computing, binary translation is a form of binary recompilation where sequences of instructions are translated from a source instruction set to the target instruction set. In some cases such as instruction set simulation, the target instruction set may be the same as the source instruction set, providing testing and ...
The pigpen cipher uses graphical symbols assigned according to a key similar to the above diagram. [1]The pigpen cipher (alternatively referred to as the masonic cipher, Freemason's cipher, Rosicrucian cipher, Napoleon cipher, and tic-tac-toe cipher) [2] [3] is a geometric simple substitution cipher, which exchanges letters for symbols which are fragments of a grid.
Tap code. The tap code, sometimes called the knock code, is a way to encode text messages on a letter-by-letter basis in a very simple way. The message is transmitted using a series of tap sounds, hence its name. [ 1] The tap code has been commonly used by prisoners to communicate with each other. The method of communicating is usually by ...
A completed nonogram of the letter "W" from the Wikipedia logo. Nonograms, also known as Hanjie, Paint by Numbers, Picross, Griddlers, and Pic-a-Pix are picture logic puzzles in which cells in a grid must be colored or left blank according to numbers at the edges of the grid to reveal a hidden picture. In this puzzle, the numbers are a form of ...
Positional notation (or place-value notation, or positional numeral system) usually denotes the extension to any base of the Hindu–Arabic numeral system (or decimal system ). More generally, a positional system is a numeral system in which the contribution of a digit to the value of a number is the value of the digit multiplied by a factor ...
The symbol is built on a square grid with a bull's-eye pattern at its centre for locating the code. Data is encoded in concentric square rings around the bull's-eye pattern. The central bull's-eye is 9×9 or 13×13 pixels , and one row of pixels around that encodes basic coding parameters, producing a "core" of 11×11 or 15×15 squares.
Russian translations. The first Russian translation of One Thousand and One Nights, in Russian: Тысяча и одна ночь ( Týsjača i odná nočʹ ), was made by Alexey Filatyev in 1763–1774. [ 8] It was based on Galland's translation and consisted of 12 volumes. [ 8] Later Russian translations were also based on European translations.
