In computing, the superuser is a special user account used for system administration.
 Depending on the operating system (OS), the actual name of this account might be root, administrator, admin or supervisor.
 In some cases, the actual name of the account is not the determining factor; on Unix-like systems, for example, the user with a user identifier (UID) of zero is the superuser, regardless of the name of that account; and in systems which implement a role based security model, any user with the role of superuser (or its synonyms) can carry out all actions of the superuser account.
Headphones (or head-phones in the early days of telephony and radio) are a pair of small loudspeaker drivers that are designed to be worn on or around the head over a user's ears.
 They are electroacoustic transducers, which convert an electrical signal to a corresponding sound in the user's ear.
 Headphones are designed to allow a single user to listen to an audio source privately, in contrast to a loudspeaker, which emits sound into the open air, for anyone nearby to hear.
 Headphones are also known as earspeakers, earphones or, colloquially, cans.
 Circumaural and supra-aural headphones use a band over the top of the head to hold the speakers in place.
 The other type, known as earbuds or earpieces consist of individual units that plug into the user's ear canal.
 In the context of telecommunication, a headset is a combination of headphone and microphone.
 Headphones connect to a signal source such as an audio amplifier, radio, CD player, portable media player, mobile phone, video game console, or electronic musical instrument, either directly using a cord, or using wireless technology such as bluetooth or FM radio.
 The first headphones were developed in the late 19th century for use by telephone operators, to keep their hands free.
 Initially the audio quality was mediocre and a step forward was the invention of high fidelity headphones.
The Portland Linux/Unix Group (PLUG) is a group of Linux and Open Source enthusiasts in Portland, Oregon.
 The group was started in early 1994 as a venue to discuss and promote Linux and Unix, and is one of the oldest Linux User Groups in existence.
 PLUG is volunteer-run and does not have any formal criteria for membership.
 Its members consider these qualities to be key to the group's endurance.
HD77 is a model name of Marantz 4-way high-fidelity loudspeakers which were produced during the mid-1970s.
 They were bass reflex speakers, but came with a cylindrical piece of foam which fit into the bass-reflex port of the enclosure if the listener preferred the more accurate bass response provided by airtight speaker boxes.
 However, they were not fully airtight this way, but rather what is known as aperiodic.
 They were designed by former JBL Engineer Edmond May.
 The foam plug in port was in fact a "closed-cell" type which did in fact seal cabinet completely.
 How it worked was it was cut slightly larger than opening and when inserted, you turned the retainer screw and it would tighten and compress the plug, thereby sealing the cabinet to make the loudspeaker a "suspension" type.
 The controls on baffle are resistive potentiometers, which changed the response curve of corresponding driver from soft to bright, giving great versatility to adapt within almost any listening environment.
TDO ("Telefonsteckdose") is the telephone plug used by A1 Telekom Austria.
Table Cape is a volcanic plug located near Wynyard on the North West of Tasmania, Australia, it is also the name of the locality which encompasses the geological feature.
 Table Cape is a more or less circular volcanic plug with a flat top, its northern and eastern faces rise steeply from Bass Strait to a height of approximately 170 m above sea level.
 It was named by British navigator, Matthew Flinders, as he and George Bass circumnavigated Van Diemen's Land (now Tasmania) in 1798 upon the "Norfolk".
 Flinders also progressively named the nearby Circular Head, Three Hummock and Hunter Islands.

CE-HTML is an XHTML-based standard for designing webpages with remote user interfaces for consumer electronic devices on Universal Plug and Play networks.
 The standard is intended for defining user interfaces that can gracefully scale on a variety of screen sizes and geometries, including those of mobile devices to high definition television sets.
A1 Telekom Austria (A) is a major Austrian fixed and mobile network operator.

Unix-like operating systems identify a user within the kernel by a value called a user identifier, often abbreviated to user ID or UID.
 The UID, along with the group identifier (GID) and other access control criteria, is used to determine which system resources a user can access.
 The password file maps textual user names to UIDs, but in the kernel, only UIDs are used.
 UIDs are stored in the inodes of the Unix file system, running processes, tar archives, and the now-obsolete Network Information Service.
 In POSIX-compliant environments, the command-line command codice_1 gives the current user's UID, as well as more information such as the user name, primary user group and group identifier (GID).

Question: Under what name the TDO plug user launched?
Answer: Mobilkom Austria
