  2. XSLT - Wikipedia

    en.wikipedia.org/wiki/XSLT

    XSLT was primarily conceived as a stylesheet language whose primary goal was to render XML for the human reader on screen, on the web (as a web template language ), or on paper. XQuery was primarily conceived as a database query language in the tradition of SQL . Because the two languages originate in different communities, XSLT is stronger in ...

    en.wikipedia.org/wiki/QR_code

    The QR code system was invented in 1994, at the Denso Wave automotive products company, in Japan. The initial alternating-square design presented by the team of researchers, headed by Masahiro Hara, was influenced by the black counters and the white counters played on a Go board; the pattern of position detection was found and determined by applying the least-used ratio (1:1:3:1:1) in black ...

  7. Steane code - Wikipedia

    en.wikipedia.org/wiki/Steane_code

    It is a CSS code (Calderbank-Shor-Steane), using the classical binary [7,4,3] Hamming code to correct for both qubit flip errors (X errors) and phase flip errors (Z errors). The Steane code encodes one logical qubit in 7 physical qubits and is able to correct arbitrary single qubit errors. Its check matrix in standard form is

  8. Control character - Wikipedia

    en.wikipedia.org/wiki/Control_character

    Control character. In computing and telecommunication, a control character or non-printing character ( NPC) is a code point in a character set that does not represent a written character or symbol.

  9. For loop - Wikipedia

    en.wikipedia.org/wiki/For_loop

    Loop constructs. In computer science a for-loop or for loop is a control flow statement for specifying iteration. Specifically, a for loop functions by running a section of code repeatedly until a certain condition has been satisfied. For-loops have two parts: a header and a body. The header defines the iteration and the body is the code that ...
