slack

<operating system>

1. Internal fragmentation. Space allocated to a disk file but not actually used to store useful information.

<jargon>

2. In the theology of the Church of the SubGenius, a mystical substance or quality that is the prerequisite of all human happiness.

Since Unix files are stored compactly, except for the unavoidable wastage in the last block or fragment, it might be said that "Unix has no slack".

See ha ha only serious.

S-Lang

<language>

A small but highly functional embedded interpreter. S-Lang was a stack-based postfix language resembling Forth and BC/DC with limited support for infix notation. Now it has a C-like infix syntax. Arrays, stings, integers, floating-point and autoloading are all suported. The editor JED embeds S-lang.

S-Lang is available under the GNU Library General Public License. It runs on MS-DOS, Unix, and VMS.

slap on the side

(Also called a sidecar, or abbreviated "SOTS"). A type of external expansion hardware marketed by computer manufacturers (e.g. Commodore for the Amiga 500/1000 series and IBM for the hideous failure called IBM PCjr). Various SOTS boxes provided necessities such as memory, hard drive controllers, and conventional expansion slots.
