Blue Glue

[IBM; obs.] IBM's SNA (Systems Network Architecture), an incredibly {losing} and {bletcherous} communications protocol once widely favored at commercial shops that didn't know any better (like other proprietary networking protocols, it became obsolete and effectively disappeared after the Internet explosion c.1994). The official IBM definition is "that which binds blue boxes together." See {fear and loathing}. It may not be irrelevant that Blue Glue is the trade name of a 3M product that is commonly used to hold down the carpet squares to the removable panel floors common in {dinosaur pen}s. A correspondent at U. Minn. reports that the CS department there has about 80 bottles of the stuff hanging about, so they often refer to any messy work to be done as using the blue glue.
