off-by-one error definition
<programming> An exceedingly common error induced in many
ways, such as by starting at zero when you should have started
at one or vice-versa, or by writing "< N" instead of "<= N" or
vice-versa. Often confounded with fencepost error, which is
properly a particular subtype of it.

offset definition
<programming> An index or position in an array, string, or
block of memory usually a non-negative integer.
E.g. the Perl function splice(ARRAY, OFFSET, LENGTH, LIST)
replaces LENGTH elements starting at index OFFSET in array
with LIST, where offset zero means the start of the array.
For an Intel x86 processor with a segmented address space
the offset is the position of a byte relative to the start
of the segment.

off-side rule definition
A lexical convention due to Landin, allowing the scope of
declarations in a program to be expressed by indentation. Any
non-whitespace token to the left of the first such token on
the previous line is taken to be the start of a new
declaration. Used in, for example, Miranda and Haskell.
