Unlambda is a minimal, "nearly pure" functional programming language invented by David Madore. It is based on combinatory logic, an expression system without the lambda operator or free variables. It relies mainly on two built-in functions (s and k) and an apply operator (written `, the backquote character). These alone make it Turing-complete, but there are also some input/output (I/O) functions to enable interacting with the user, some shortcut functions, and a lazy evaluation function. Variables are unsupported.

Unlambda is free and open-source software distributed under a GNU General Public License (GPL) 2.0 or later.

Wireless USB was a short-range, high-bandwidth wireless radio communication protocol created by the Wireless USB Promoter Group which intended to increase the availability of general USB-based technologies. It is unrelated to Wi-Fi. It was maintained by the WiMedia Alliance which ceased operations in 2009. Wireless USB is sometimes abbreviated as "WUSB", although the USB Implementers Forum discouraged this practice and instead prefers to call the technology Certified Wireless USB to distinguish it from the competing UWB standard.

Wireless USB was based on the (now defunct) WiMedia Alliance's Ultra-WideBand (UWB) common radio platform, which is capable of sending 480 Mbit/s at distances up to 3 metres (9.8 ft) and 110 Mbit/s at up to 10 metres (33 ft). It was designed to operate in the 3.1 to 10.6 GHz frequency range, although local regulatory policies may restrict the legal operating range in some countries.

The standard is now obsolete, and no new hardware has been produced for many years.

Microsoft Works is a discontinued productivity software suite developed by Microsoft and sold from 1987 to 2009. Its core functionality included a word processor, a spreadsheet and a database management system. Later versions had a calendar application and a dictionary while older releases included a terminal emulator. Works was available as a standalone program, and as part of a namesake home productivity suite. Because of its low cost ($40 retail, or as low as $2 OEM), companies frequently pre-installed Works on their low-cost machines. Works was smaller, less expensive, and had fewer features than Microsoft Office and other major office suites available at the time.

Mainstream support for the final standalone and suite release ended on October 9, 2012 and January 8, 2013, respectively.

In computing, minimalism refers to the application of minimalist philosophies and principles in the design and use of hardware and software. Minimalism, in this sense, means designing systems that use the least hardware and software resources possible.

Model M designates a group of computer keyboards designed and manufactured by IBM starting in 1984, and later by Lexmark International, Maxi Switch, and Unicomp. The keyboard's many variations have their own distinct characteristics, with the vast majority having a buckling-spring key design and swappable keycaps. Model M keyboards have been praised by computer enthusiasts and frequent typists due to their durability and consistency, and the tactile and auditory feedback they provide.

The Model M is also regarded as a timeless and durable piece of hardware. Although the computers and computer peripherals produced concurrently with the Model M are considered obsolete, many Model M keyboards are still in use due to their physical durability and the continued validity of their ANSI 101-key and ISO 102-key layouts, through the use of a PS/2 female to USB male adapter with a built-in level converter. Since their original popularity, new generations of writers and computer technicians have rediscovered their unique functionality and aesthetics. The Kentucky-based company Unicomp continues to manufacture and sell Model M keyboards.

Halt and Catch Fire is an American period drama television series created by Christopher Cantwell and Christopher C. Rogers. It aired on the cable network AMC in the United States from June 1, 2014, to October 14, 2017, spanning four seasons and 40 episodes. Taking place over a period of more than ten years, the series depicts a fictionalized insider's view of the personal computer revolution of the 1980s and the growth of the World Wide Web in the early 1990s. The show's title refers to computer machine code instruction Halt and Catch Fire (HCF), the execution of which would cause the computer's central processing unit to stop working (catch fire being a humorous exaggeration).

In season one, the company Cardiff Electric makes its first foray into personal computing, with entrepreneur Joe MacMillan (Lee Pace) running a project to build an IBM PC clone with the help of computer engineer Gordon Clark (Scoot McNairy) and prodigy programmer Cameron Howe (Mackenzie Davis). Seasons two and three shift focus to a startup company, the online community Mutiny, that is headed by Cameron and Gordon's wife Donna (Kerry Bishé), while Joe ventures out on his own. The fourth and final season focuses on competing web search engines involving all the principal characters.

Halt and Catch Fire marked Cantwell's and Rogers's first jobs in television. They wrote the pilot hoping to use it to secure jobs as writers in the industry but instead landed a series of their own from AMC. The story was inspired by Cantwell's childhood in the Silicon Prairie of Dallas–Fort Worth, where his father worked as a software salesman, and the creators' subsequent research into Texas's role in personal computing innovations of the 1980s. Filmed in the Atlanta, Georgia, area and produced by the network, the series is set in the Silicon Prairie for its first two seasons and Silicon Valley for its latter two.

Halt and Catch Fire debuted to generally favorable reviews, though many reviewers initially found it derivative of other series such as Mad Men. In each subsequent season, the series grew in acclaim, and by the time it concluded, critics considered it among the best shows of the 2010s. Despite its critical reception, the series experienced low viewership ratings throughout its run, with only the first episode surpassing one million viewers for its initial broadcast.

Mark V. Shaney is a synthetic Usenet user whose postings in the net.singles newsgroups were generated by Markov chain techniques, based on text from other postings. The username is a play on the words "Markov chain". Many readers were fooled into thinking that the quirky, sometimes uncannily topical posts were written by a real person.

The system was designed by Rob Pike with coding by Bruce Ellis. Don P. Mitchell wrote the Markov chain code, initially demonstrating it to Pike and Ellis using the Tao Te Ching as a basis. They chose to apply it to the net.singles netnews group.

In computing, a Parallel Sysplex is a cluster of IBM mainframes acting together as a single system image with z/OS. Used for disaster recovery, Parallel Sysplex combines data sharing and parallel computing to allow a cluster of up to 32 systems to share a workload for high performance and high availability.

A wetware computer is an organic computer (which can also be known as an artificial organic brain or a neurocomputer) composed of organic material such as living neurons. Wetware computers composed of neurons are different than conventional computers because they are thought to be capable in a way of "thinking for themselves", because of the dynamic nature of neurons. While wetware is still largely conceptual, there has been limited success with construction and prototyping, which has acted as a proof of the concept's realistic application to computing in the future. The most notable prototypes have stemmed from the research completed by biological engineer William Ditto during his time at the Georgia Institute of Technology. His work constructing a simple neurocomputer capable of basic addition from leech neurons in 1999 was a significant discovery for the concept. This research acted as a primary example driving interest in the creation of these artificially constructed, but still organic brains.

A Kensington Security Slot (also called a K-Slot or Kensington lock) is part of an anti-theft system designed in the early 1990s and patented by Kryptonite in 1999–2000, assigned to Schlage in 2002, and since 2005 owned and marketed by Kensington Computer Products Group, a division of ACCO Brands.
