U+20DB ⃛ COMBINING THREE DOTS ABOVE character is a combining diacritical mark for symbols. When used after U+0020 SPACE, it is used in mathematical notations (and represented with the "tdot" or "TripleDot" entities in HTML 5.0 and MathML 3.0) In music notation, a triple-dotted note is a note with three dots written after it
It states that two instances of similar code do not require refactoring, but when similar code is used three times, it should be extracted into a new procedure. The rule was popularised by Martin Fowler in Refactoring [1] and attributed to Don Roberts. Duplication is considered a bad practice in programming because it makes the code harder to ...
It uses 8-dot patterns to represent 256 different values so arbitrary byte data can be written in Braille. The 8-dot code is designed that its 6-dot subset is identical to the 6-dot code. The remainder are assigned by the following rules: adding dot 7 subtracts 32 from the ASCII value; adding dot 8 adds 128 to the ASCII value;
The Braille pattern dots-2346 ( ⠮) is a 6-dot braille cell with the top right, middle left, and both bottom dots raised, or an 8-dot braille cell with the top right, upper-middle left, and both lower-middle dots raised. It is represented by the Unicode code point U+282e, and in Braille ASCII with an exclamation mark: !.
[3] A similar syntax is method cascading, where after the method call the expression evaluates to the current object, not the return value of the method. Cascading can be implemented using method chaining by having the method return the current object itself.
The ellipsis (/ ə ˈ l ɪ p s ɪ s /, plural ellipses; from Ancient Greek: ἔλλειψις, élleipsis, lit. ' leave out ' [1]), rendered ..., alternatively described as suspension points [2]: 19 /dots, points [2]: 19 /periods of ellipsis, or ellipsis points, [2]: 19 or colloquially, dot-dot-dot, [3] [4] is a punctuation mark consisting of a series of three dots.
The Braille pattern dots-3 ( ⠄) is a 6-dot braille cell with the bottom left dot raised, or an 8-dot braille cell with the middle-bottom left dot raised. It is represented by the Unicode code point U+2804, and in Braille ASCII with an apostrophe.
Tacit programming, also called point-free style, is a programming paradigm in which function definitions do not identify the arguments (or "points") on which they operate. Instead the definitions merely compose other functions, among which are combinators that manipulate the arguments.
