    en.wikipedia.org/wiki/Delete_character

    The delete control character (also called DEL or rubout) is the last character in the ASCII repertoire, with the code 127. [1] It is supposed to do nothing and was designed to erase incorrect characters on paper tape. It is denoted as ^? in caret notation and is U+007F in Unicode.

  3. Indentation style - Wikipedia

    en.wikipedia.org/wiki/Indentation_style

    In computer programming, indentation style is a convention, a.k.a. style, governing the indentation of blocks of source code.An indentation style generally involves consistent width of whitespace (indentation size) before each line of a block, so that the lines of code appear to be related, and dictates whether to use space or tab characters for the indentation whitespace.

    In the simple case where k = 2, redundancy symbols may be created by sampling different points along the line between the two original symbols. This is pictured with a simple example, called err-mail: Alice wants to send her telephone number (555629) to Bob using err-mail. Err-mail works just like e-mail, except

  5. Array programming - Wikipedia

    The cross product operation is an example of a vector rank function because it operates on vectors, not scalars. Matrix multiplication is an example of a 2-rank function, because it operates on 2-dimensional objects (matrices). Collapse operators reduce the dimensionality of an input data array by one or more dimensions. For example, summing ...

    The free statistical package R (see R programming language) can make a wide variety of nice-looking graphics. It is especially effective to display statistical data. On Wikimedia Commons, the category Created with R contains many examples, often including the corresponding R source code. Other examples can be found in the R Graph Gallery.

    However, if your code works with the content part of the page (the #mw-content-text element), you should use the 'wikipage.content' hook instead. This way your code will successfully reprocess the page when it is updated asynchronously and the hook is fired again. There are plenty of tools that do so, ranging from edit preview to watchlist ...

  8. Vector graphics - Wikipedia

    en.wikipedia.org/wiki/Vector_graphics

    A free software Asteroids-like video game played on a vector monitor. Vector-based devices, such as the vector CRT and the pen plotter, directly control a drawing mechanism to produce geometric shapes. Since vector display devices can define a line by dealing with just two points (that is, the coordinates of each end of the line), the device ...

    As an example a VHDL compiler may create an SVF file that is read by a tool for programming CPLDs. The SVF file is defined as an ASCII file that consists of a set of SVF statements. The maximum number of characters allowed on a line is 256, although one SVF statement can span more than one line.
