transitive verb

• to pester or annoy.

  by Anonymous, Sep 28 2008.

origin

• Regarding the "unwanted and unintended property" meaning:
  
  Admiral Grace Hopper (an early computing pioneer better known for inventing the programming language COBOL) liked to tell a story in which a technician solved a malfunction in the Harvard Mark II machine by pulling an actual insect out from between the contacts of one of its relays, and she subsequently promulgated "bug" in its hackish sense as a joke about the incident (though, as she was careful to admit, she was not there when it happened). For many years the logbook associated with the incident and the actual bug in question (a moth) sat in a display case at the Naval Surface Warfare Center (NSWC). The entire story, with a picture of the logbook and the moth taped into it, is recorded in the Annals of the History of Computing, Vol. 3, No. 3 (July 1981), pp. 285--286. The text of the log entry (from September 9, 1947), reads, "1545 Relay #70 Panel F (moth) in relay. First actual case of bug being found."
  
  This wording establishes that the term was already in use at the time in its current specific sense, and Hopper herself reports that the term "bug" was regularly applied to problems in radar electronics during WWII.
  
  Indeed, the use of "bug" to mean an industrial defect was already established in Thomas Edison's time, and a more specific and rather modern use can be found in an electrical handbook from 1896 (Hawkin's New Catechism of Electricity, Theo. Audel & Co.) which says, "The term "bug" is used to a limited extent to designate any fault or trouble in the connections or working of electric apparatus."
  
  It further notes that the term is said to have originated in quadruplex telegraphy and have been transferred to all electric apparatus.
  
  The latter observation may explain a common folk etymology of the term: that it came from telephone company usage, in which bugs in a telephone cable were blamed for noisy lines.
  
  Historians of the field inform us that the term was regularly used in the early days of telegraphy to refer to a variety of semi-automatic telegraphy keyers that would send a string of dots if you held them down. In fact, the Vibroplex keyers (which were among the most common of this type) even had a graphic of a beetle on them (and still do)! While the ability to send repeated dots automatically was very useful for professional morse code operators, these were also significantly trickier to use than the older manual keyers, and it could take some practice to ensure one didn't introduce extraneous dots into the code by holding the key down a fraction too long. In the hands of an inexperienced operator, a Vibroplex "bug" on the line could mean that a lot of garbled Morse would soon be coming your way.
  
  Further, the term has long been used among radio technicians to describe a device that converts electromagnetic field variations into acoustic signals. It is used to trace radio interference and look for dangerous radio emissions. Radio community usage derives from the roach-like shape of the first versions used by 19th century physicists. The first versions consisted of a coil of wire (roach body), with the two wire ends sticking out and bent back to nearly touch forming a spark gap (roach antennae). The bug is to the radio technician what the stethoscope is to the stereotypical medical doctor. This sense is almost certainly ancestral to modern use of "bug" meaning a covert monitoring device, but may also have contributed to the use of the term for the effects of radio interference itself.
  
  Actually, use of "bug" in the general sense of a disruptive event goes back to Shakespeare! (Henry VI, part III - Act V, Scene II: King Edward:
  
  "So, lie thou there. Die thou; and die our fear; For Warwick was a bug that fear'd us all."
  
  In the first edition of Samuel Johnson's dictionary one meaning of "bug" is "A frightful object; a walking spectre." This is traced to "bugbear", a Welsh term for a variety of mythological monster which (to complete the circle) has recently been reintroduced into the popular lexicon through fantasy role-playing games. In any case, in jargon the word almost never refers to insects.
  
  A careful discussion of the etymological issues can be found in a paper by Fred R. Shapiro, 1987, "Entomology of the Computer Bug: History and Folklore", American Speech 62(4):376-378.
  
  As of late 1990, the NSWC still had the bug, but had unsuccessfully tried to get the Smithsonian to accept it. The present curator of their History of American Technology Museum didn't know this and agreed that it would make a worthwhile exhibit. It was moved to the Smithsonian in mid-1991, but due to space and money constraints was not actually exhibited for years afterwards.
