Software Bug
A software bug is an error, flaw or fault in the design, development, or operation of computer software that causes it to produce an incorrect or unexpected result, or to behave in unintended ways. The process of finding and correcting bugs is termed "debugging" and often uses formal techniques or tools to pinpoint bugs. Since the 1950s, some computer systems have been designed to deter, detect or auto-correct various computer bugs during operations. Bugs in software can arise from mistakes and errors made in interpreting and extracting users' requirements, planning a program's design, writing its source code, and from interaction with humans, hardware and programs, such as operating systems or libraries. A program with many, or serious, bugs is often described as ''buggy''. Bugs can trigger errors that may have ripple effects. The effects of bugs may be subtle, such as unintended text formatting, through to more obvious effects such as causing a program to crash, freezing th ...

MediaWiki
MediaWiki is a free and open-source wiki software. It is used on Wikipedia and almost all other Wikimedia websites, including Wiktionary, Wikimedia Commons and Wikidata; these sites define a large part of the requirement set for MediaWiki. It was developed for use on Wikipedia in 2002, and given the name "MediaWiki" in 2003. MediaWiki was originally developed by Magnus Manske and improved by Lee Daniel Crocker. Magnus Manske's announcement of "PHP Wikipedia", wikipedia-l, August 24, 2001 Its development has since then been coordinated by the Wikimedia Foundation. MediaWiki is written in the PHP programming language and stores all text content into a database. The software is optimized to efficiently handle large projects, which can have terabytes of content and hundreds of thousands of views per second. Because Wikipedia is one of the world's largest websites, achieving scalability through multiple layers of caching and database replication has been a major concern ...

Radiation Therapy
Radiation therapy or radiotherapy, often abbreviated RT, RTx, or XRT, is a therapy using ionizing radiation, generally provided as part of cancer treatment to control or kill malignant cells and normally delivered by a linear accelerator. Radiation therapy may be curative in a number of types of cancer if they are localized to one area of the body. It may also be used as part of adjuvant therapy, to prevent tumor recurrence after surgery to remove a primary malignant tumor (for example, early stages of breast cancer). Radiation therapy is synergistic with chemotherapy, and has been used before, during, and after chemotherapy in susceptible cancers. The subspecialty of oncology concerned with radiotherapy is called radiation oncology. A physician who practices in this subspecialty is a radiation oncologist. Radiation therapy is commonly applied to the cancerous tumor because of its ability to control cell growth. Ionizing radiation works by damaging the DNA of cancerous tissue ...

Baffle Ball
''Baffle Ball'' is a pinball machine created in November 19, 1931 by David Gottlieb, founder of the Gottlieb amusement company. Gameplay For one US cent players get ten balls. These balls are fired up onto the playfield and fall into pockets and holes. Some ball targets are worth more than others, and players try to fire the ball at just the right speed. Unlike later pinball machines, ''Baffle Ball'' does not have flippers. The best target is the Baffle Ball, a tiny hole at the top which doubles all points. The game uses no electricity, and all scoring has to be done by hand. Description While bagatelle-derived "marble games" have long existed previously, ''Baffle Ball'' was the first commercially successful game of its type, being affordable enough for store and tavern owners to quickly recoup the machine's cost. Over 50,000 machines were made, jump-starting the arcade pinball field; it spawned a home version in 1932 called ''Baffle Ball Senior''.

Thomas Edison
Thomas Alva Edison (February 11, 1847October 18, 1931) was an American inventor and businessman. He developed many devices in fields such as electric power generation, mass communication, sound recording, and motion pictures. These inventions, which include the phonograph, the motion picture camera, and early versions of the electric light bulb, have had a widespread impact on the modern industrialized world. He was one of the first inventors to apply the principles of organized science and teamwork to the process of invention, working with many researchers and employees. He established the first industrial research laboratory. Edison was raised in the American Midwest. Early in his career he worked as a telegraph operator, which inspired some of his earliest inventions. In 1876, he established his first laboratory facility in Menlo Park, New Jersey, where many of his early inventions were developed. He later established a botanical laboratory in Fort Myers, Florida, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bugbear
A bugbear is a legendary creature or type of hobgoblin comparable to the boogeyman (or bugaboo or babau or cucuy), and other creatures of folklore, all of which were historically used in some cultures to frighten disobedient children. Etymology Its name is derived from the Middle English word "bugge" (a frightening thing), or perhaps the Old Welsh word ''bwg'' (evil spirit or goblin), or Old Scots ''bogill'' (goblin), and cognates most probably English "bogeyman" and "bugaboo". In medieval England, the bugbear was depicted as a creepy bear that lurked in the woods to scare children. It was described in this manner in ''The Buggbears'', an adaptation, with additions, from Antonio Francesco Grazzini’s ''La Spiritata'' (‘The Possessed oman��, 1561). In a modern context, the term ''bugbear'' may also mean pet peeve. In popular culture Bugbears appear in a number of modern fantasy literature and related media, where they are usually minor antagonists. They also appear as monst ...

British Post Office Scandal
The British Post Office scandal is a miscarriage of justice involving the wrongful civil and criminal prosecutions of an unknown or unpublished number of sub-postmasters (SPMs) for theft, false accounting and/or fraud. The cases constitute the most widespread miscarriage of justice in British legal history, spanning a period of over twenty years and it remains unresolved. After some convicted SPMs successfully sued the Post Office, 555 convictions were declared unsafe and to have been obtained unlawfully. By 2022, 736 prosecutions had been identified, 81 convictions had been overturned and more were expected to be quashed. The number of those affected by other types of abuse by the Post Office, torts, breach of contract, coercion etc., has not been tabulated or published. The prosecutions, civil actions, and extortions resulted in criminal convictions, false confessions, imprisonments, defamation, loss of livelihood, bankruptcy, divorce, and suicide.

FADEC
A full authority digital engine (or electronics) control (FADEC) is a system consisting of a digital computer, called an "electronic engine controller" (EEC) or "engine control unit" (ECU), and its related accessories that control all aspects of aircraft engine performance. FADECs have been produced for both piston engines and jet engines. History The goal of any engine control system is to allow the engine to perform at maximum efficiency for a given condition. Originally, engine control systems consisted of simple mechanical linkages connected physically to the engine. By moving these levers the pilot or the flight engineer could control fuel flow, power output, and many other engine parameters. The mechanical/hydraulic engine control unit for Germany's BMW 801 piston aviation radial engine of World War II was just one notable example of this in its later stages of development. This mechanical engine control was progressively replaced first by analog electronic engine control ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
