shim

|
|
n. 1. A small piece of data inserted in order to achieve a desired memory
|
|
alignment or other addressing property. For example, the PDP-11 Unix linker,
|
|
in split I D (instructions and data) mode, inserts a two-byte shim at
|
|
location 0 in data space so that no data object will have an address of 0
|
|
(and be confused with the C null pointer). See also loose bytes. 2. A type
|
|
of small transparent image inserted into HTML documents by certain WYSIWYG
|
|
HTML editors, used to set the spacing of elements meant to have a fixed
|
|
positioning within a TABLE or DIVision. Hackers who work on the HTML code of
|
|
such pages afterwards invariably curse these for their crocky dependence on
|
|
the particular spacing of original image file, the editor that generated
|
|
them, and the version of the browser used to view them. Worse, they are a
|
|
poorly designed kludge which the advent of Cascading Style Sheets makes
|
|
wholly unnecessary; Any fool can plainly see that use of borders, layers and
|
|
positioned elements is the Right Thing (or would be if adequate support for
|
|
CSS were more common).
