  2. Reference counting - Wikipedia

    en.wikipedia.org/wiki/Reference_counting

    The reference count of a string is checked before mutating a string. This allows reference count 1 strings to be mutated directly whilst higher reference count strings are copied before mutation. This allows the general behaviour of old style pascal strings to be preserved whilst eliminating the cost of copying the string on every assignment.

  3. Circular reference - Wikipedia

    en.wikipedia.org/wiki/Circular_reference

    For example, if the value in Cell A1 is to be obtained by adding 5 to the value in Cell B1, and the value in Cell B1 is to be obtained by adding 3 to the value in Cell A1, no values can be computed. (Even if the specifications are A1:=B1+5 and B1:=A1-5, there is still a circular reference.

  4. Source lines of code - Wikipedia

    en.wikipedia.org/wiki/Source_lines_of_code

    1 comment line: tools must account for all code and comments regardless of comment placement. Even the "logical" and "physical" SLOC values can have a large number of varying definitions. Robert E. Park (while at the Software Engineering Institute ) and others developed a framework for defining SLOC values, to enable people to carefully explain ...

  5. Foreach loop - Wikipedia

    en.wikipedia.org/wiki/Foreach_loop

    In computer programming, foreach loop (or for-each loop) is a control flow statement for traversing items in a collection. foreach is usually used in place of a standard for loop statement.

  6. Indirection - Wikipedia

    en.wikipedia.org/wiki/Indirection

    In computer programming, an indirection (also called a reference) is a way of referring to something using a name, reference, or container instead of the value itself. The most common form of indirection is the act of manipulating a value through its memory address .

  7. CPython - Wikipedia

    en.wikipedia.org/wiki/CPython

    Python is typically used at the top level and calls functions in libraries to perform specialized tasks. These libraries are generally not written in Python, and Python code in another thread can be executed while a call to one of these underlying processes takes place.

  8. Automatic Reference Counting - Wikipedia

    en.wikipedia.org/wiki/Automatic_Reference_Counting

    Automatic Reference Counting (ARC) is a memory management feature of the Clang compiler providing automatic reference counting for the Objective-C and Swift programming languages. At compile time, it inserts into the object code messages retain and release [ 1 ] [ 2 ] which increase and decrease the reference count at run time, marking for ...

  9. Carry (arithmetic) - Wikipedia

    en.wikipedia.org/wiki/Carry_(arithmetic)

    Kummer's theorem states that the number of carries involved in adding two numbers in base is equal to the exponent of the highest power of dividing a certain binomial coefficient. When several random numbers of many digits are added, the statistics of the carry digits bears an unexpected connection with Eulerian numbers and the statistics of ...
