*}} |caption=Classic use of "luser" at the [ITS](/source/Incompatible_Timesharing_System) login screen }} Before the popularization of the Internet in the 1990s, [Internet slang](/source/Internet_slang) defined a '''luser''' (sometimes expanded to '''local user'''; also '''luzer''' or '''luzzer''') as a painfully annoying, stupid, or irritating [computer user](/source/computer_user).{{cite book | title = The Complete Idiot's Guide to a Smart Vocabulary | first = Paul | last = McFedries | publisher = Alpha Books | year = 2001 | isbn = 0-02-863997-9 | url = https://archive.org/details/completeidiotsgu0000mcfe_p6s6 }}p. 214 The word is a [blend](/source/Blend_word) of "loser" and "user".{{cite book | title = Netlingo: The Internet Dictionary | first = Erin | last = Jansen | publisher = NetLingo Inc. | year = 2002 | isbn = 0-9706396-7-8 | url = https://archive.org/details/00book881123420 }}p. 244 Among [hackers](/source/Hacker_(programmer_subculture)), the word ''luser'' takes on a broad meaning, referring to any normal [user](/source/user_(computing)) (in other words, not a "[guru](/source/Expert)"), with the implication the person is also a [loser](/source/Loser_(person)). The term is partially interchangeable with the hacker term ''[lamer](/source/lamer)''. The term can also signify a [layman](/source/layman) with only [user](/source/user_(computing)) account [privileges](/source/Privilege_(computing)), as opposed to a [power user](/source/power_user) or [administrator](/source/Superuser), who has knowledge of, and access to, [superuser](/source/superuser) accounts; for example, an '''[end luser](/source/End-user_(computer_science))''' who cannot be trusted with a root account for [system administration](/source/system_administration). It is popular with technical support staff who have to deal with lusers as part of their job, often metaphorically employing a '''LART''' ('''Luser Attitude Readjustment Tool''', also known as a '''clue-by-four''',{{cite web |title=clue by four |url=https://idioms.thefreedictionary.com/clue-by-four |website=The Free Dictionary}} '''cluestick''', or '''cluebat'''), meaning turning off the user's access to computer resources and the like. ==History== The [Jargon File](/source/Jargon_File) states that the word was coined around 1975 at [MIT](/source/Massachusetts_Institute_of_Technology),{{cite web|url=http://catb.org/jargon/html/L/luser.html|title=luser|access-date=6 October 2014}} although LUSER is visible in [CTSS](/source/Compatible_Time-Sharing_System) source code circa 1969 in subroutines involving spying on and killing users and deleting their files and directories.{{cite web |url=https://raw.githubusercontent.com/rcornwell/ctss/master/original/com1 |title=ADMIN - Administrator Privleged Commands |last=Roach |first=Roger A. |date=1969 |website=Github |publisher=Massachusetts Institute of Technology |access-date=April 5, 2022}} Under [ITS](/source/Incompatible_Timesharing_System), when a user first walked up to a terminal at MIT and typed [control-Z](/source/control-Z) to get the computer's attention, it printed out some status information, including how many people were already using the computer. A patch to the system was then written to print "14 losers" instead of "14 users", as a joke. For a while, several [hackers](/source/Hacker_(computer_security)) who disagreed on the appropriateness of the change struggled covertly, each changing the message behind the backs of the others; any time a user logged into the computer it was equally probable that a user would see, say, "users" or "losers". Finally, someone tried the compromise "lusers", and it stuck. Later, [ITS](/source/Incompatible_Timesharing_System) also had the command "luser", which attempted to summon assistance from a list of designated helpers. Although ITS ceased to be used in the mid-1990s, use of the term continued to spread, partly because in [Unix](/source/Unix)-style computer operating systems, "[user](/source/User_(computing))" designates all unprivileged accounts, while the [superuser](/source/superuser), or root, is the special user account used for system administration. "root" is the conventional name of the user who has all rights or permissions (to all files and programs) in all modes (single- or multi-user). The usage lives on, however, and the term "luser" is often seen in program comments and on [Usenet](/source/Usenet). On [IRC](/source/Internet_Relay_Chat), /lusers (which abbreviates "list users") is a common command to get the number of users connected to a server or network.{{cite web|url=http://www.irchelp.org/irchelp/misc/ccosmos.html#Heading852|title=irchelp.org|access-date=6 October 2014}} ==See also== * [Any key](/source/Any_key) * [Banhammer](/source/Banhammer) * [BOFH](/source/BOFH) * [id10t](/source/id10t) * [Lamer](/source/Lamer) * [Layer 8](/source/Layer_8) * [Newbie](/source/Newbie) * [PEBKAC](/source/PEBKAC) * [Power user](/source/Power_user) ==Notes and references== {{reflist}} == External links == * {{Wiktionary-inline|cluebat}} * {{Wiktionary-inline|luser}} {{JargonFile}} Category:Internet slang Category:IRC Category:Pejorative terms for people Category:Hacker culture --- Adapted from the Wikipedia article [Luser](https://en.wikipedia.org/wiki/Luser) by Wikipedia contributors ([contributor history](https://en.wikipedia.org/wiki/Luser?action=history)).
