"Gremlin is an English folkloric creature, commonly depicted as mischievous and mechanically oriented... The concept of gremlins responsible for sabotaging aircraft was popularised during World War II... The creatures were responsible for otherwise inexplicable accidents which sometimes occurred during their flights. Gremlins were also thought at one point to have enemy sympathies, but investigations revealed that enemy planes had similar and equally inexplicable mechanical problems. As such, gremlins were portrayed as being equal opportunity tricksters, taking no sides in the conflict, and acting out their mischief from their own self-interests."http://en.wikipedia.org/wiki/Gremlin
Computer Gremlins, the unseen menace
Few people know it, but Silicon Valley was once a major home for gremlins. As the computer people set up shop and ruined the magic gremlin forest, gremlins decided to make life a little more annoying for computer users everywhere. These gremlins are specially developed strains, different in many ways from the ones that bothered the RAF during World War II. Scientists have discovered the following distinct sorts of computer gremlin:
(Graemlin irritatis algorithmii)
This gremlin subspecies is the archnemesis of coders and hackers everywhere, probably because their home was ruined by caffeine-slurping coding geeks. They lurk within the computers of hackers, and are the prime reason why hackers praise the Gods of Debugging. Whenever the hacker is not 100% focused on the task, the logic saboteur will introduce bugs into the code and enjoy the look on the baffled hacker's face. They have the special ability to turn their bugs invisible, but only to the hacker who was hacking while the gremlin worked its mischief.
(Graemlin irritatis electromechanicus)
Possibly the least specialized of the computer gremlins, these delight in figuring out how hardware components work, often failing to put them back together in functional order. They will take apart your slot-in DVD-ROM while you're not home, and mess up the loading mechanism in the process. They especially like fooling around with overclocked processors and water-cooling rigs. Their preferred habitat is i386 PCs, the cases of Macintoshes are too small for them, and big UNIX servers and mainframes are too hot.
Phantoms of the Operating System
(Graemlin irritatis systematicus)
(Graemlin irritatis teeceepipensis)
Primarily residing at ISPs and in other large networking hubs, these live inside routers and servers. They speak TCP/IP fluently, and take delight in randomly rearranging the flow of packets to make the network do strange things. They take servers down when they need to sleep, and are the cause of many a happy 404. The BIND DNS server software is a favoured home of these.
Several other computer gremlins exist, but these are by far the most abundant.
