A small piece of data inserted in order to achieve a desired
|
|||
|
|
memory alignment or other addressing property. For example, the <a href="../P/PDP-11.html"><i class="glossterm">PDP-11</i></a>
|
|||
|
|
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
|
|||
|
|
<a href="../L/loose-bytes.html"><i class="glossterm">loose bytes</i></a>. </p></dd><dd><p> 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 <a href="../K/kludge.html"><i class="glossterm">kludge</i></a> 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).</p></dd><div class="navfooter"><hr/><table width="100%" summary="Navigation footer"><tr><td width="40%" align="left"><a accesskey="p" href="shift-left-or-right-logical.html">Prev</a><EFBFBD></td><td width="20%" align="center"><a accesskey="u" href="../S.html">Up</a></td><td width="40%" align="right"><EFBFBD><a accesskey="n" href="shitogram.html">Next</a></td></tr><tr><td width="40%" align="left" valign="top">shift left (or right) logical<61></td><td width="20%" align="center"><a accesskey="h" href="../index.html">Home</a></td><td width="40%" align="right" valign="top"><EFBFBD>shitogram</td></tr></table></div></body></html>
