  2. Floyd's triangle - Wikipedia

    en.wikipedia.org/wiki/Floyd's_triangle

    The numbers along the left edge of the triangle are the lazy caterer's sequence and the numbers along the right edge are the triangular numbers. The n th row sums to n ( n 2 + 1)/2 , the constant of an n × n magic square (sequence A006003 in the OEIS ).

    Parameter 3: dd, Decimal character code, 13 digits (e.g., 32) For example, the first four ASCII control characters ( Unicode U+0000 thru U+0003, decimal 0 thru 3) are coded as rows in a character set table like this:

  4. Tracing garbage collection - Wikipedia

    Second, the interpretation of the black/white bit can change. Initially, the black/white bit may have the sense of (0=white, 1=black). If an allocation operation ever fails to find any available (white) memory, that means all objects are marked used (black). The sense of the black/white bit is then inverted (for example, 0=black, 1=white).

    By convention the position on a sheet of paper where the first print line has to be written is associated with Channel 1. For example, if the first line of text has to always be on physical line 3 for a given form, then the channel 1 hole has to be punched in line 3 of the carriage control tape.

  6. Code property graph - Wikipedia

    en.wikipedia.org/wiki/Code_property_graph

    In computer science, a code property graph (CPG) is a computer program representation that captures syntactic structure, control flow, and data dependencies in a property graph. The concept was originally introduced to identify security vulnerabilities in C and C++ system code, [ 1 ] but has since been employed to analyze web applications , [ 2 ...

  7. Template:Periodic table (left step) - Wikipedia

    en.wikipedia.org/wiki/Template:Periodic_table...

    This form of periodic table is congruent with the order in which electron shells are ideally filled according to the Madelung rule, as shown in the accompanying sequence in the left margin (read from top to bottom, left to right). The experimentally determined ground-state electron configurations of the elements differ from the configurations ...

  8. Periodic table (electron configurations) - Wikipedia

    en.wikipedia.org/wiki/Periodic_table_(electron...

    In many cases, multiple configurations are within a small range of energies and the small irregularities that arise in the d- and f-blocks are quite irrelevant chemically. [1] The construction of the periodic table ignores these irregularities and is based on ideal electron configurations.

  9. Box-drawing characters - Wikipedia

    en.wikipedia.org/wiki/Box-drawing_characters

    The hardware code page of the original IBM PC supplied the following box-drawing characters, in what DOS now calls code page 437. This subset of the Unicode box-drawing characters is thus included in WGL4 and is far more popular and likely to be rendered correctly:
