Portal (interactive novel)

Portal is a mix between a computerized novel and an interactive game. It was published for the Amiga in 1986 by Activision, written by Rob Swigart, produced by Brad Fregger, and programmed by Nexa Corporation. Versions for the Commodore 64, Apple II, and DOS were later released. Versions for the Macintosh and Atari ST were announced and developed, but never formally released. A unique game for its time, Portal was one part text-driven adventure (à la Zork or Planetfall) but with a graphical interface. It is unrelated to the game Portal (2007) by Valve Corporation.

Setting

The player, taking on the role of the unnamed astronaut protagonist, returns from a failed 100-year voyage to 61 Cygni to find the Earth devoid of humans. Cars are rusted and covered with moss, the streets are completely barren and everything appears as though the entire human race had just vanished suddenly. The player happens upon a barely functioning computer terminal that is tied into a storytelling mainframe, Homer. Through this interface, the player, assisted by Homer who attempts to weave the information into a coherent narrative, discovers information in order to piece together the occurrences leading to the disappearance of the human race. For instance, spending some time in the Medical Records section may unlock a piece of data in the Science section, and through these links the player can finish the game.

Portal (architecture)

A portal is an opening in a wall of a building, gate or fortification, especially a grand entrance to an important structure.doors, metal gates or portcullis in the opening can be used to control entry or exit. The surface surrounding the opening may be made of simple building materials or decorated with ornamentation. The elements of a portal can include the voussoir, tympanum, an ornamented mullion or trumeau between doors, and columns with carvings of saints in the westwork of a church.

Linux kernel

The Linux kernel is a Unix-like computer operating system kernel. It is used world-wide: the Linux operating system is based on it and deployed on both traditional computer systems such as personal computers and servers, usually in the form of Linux distributions, and on various embedded devices such as routers and NAS appliances. The Android operating system for tablet computers, smartphones and smartwatches is also based atop the Linux kernel.

The Linux kernel was conceived and created in 1991, by Finnish computer science student Linus Torvalds for his personal computer and with no cross-platform intentions, but has since expanded to support a huge array of computer architectures, many more than other operating systems or kernels. Linux rapidly attracted developers and users who adapted code from other free software projects for use with the new operating system. The Linux kernel has received contributions from nearly 12,000 programmers from more than 1,200 companies, including some of the largest software and hardware vendors.

CompTIA

The Computing Technology Industry Association (CompTIA), a non-profit trade association, was created in 1982 as the Association of Better Computer Dealers (ABCD). ABCD later changed its name to the Computing Technology Industry Association to reflect the association's evolving role in the computer industry and in the U.S. business landscape at large. The 1990s was a period of growth as the association broadened the scope of its activities to address the needs of the expanding computer industry. Its initiatives increased to include networking, UNIX, imaging, mobile computing, and multimedia arenas. In an effort to monitor and take positions on public policy issues, the association added a full-time Director of Public Policy. In 2010, CompTIA added a new executive director for a newly named "Creating IT Futures" Foundation, its philanthropic arm that focuses on training and certifying low-income students and adults in IT, as well as returning veterans—and helping connect them with potential employers.
