Blue Smoke (electronics)
Magic smoke (also factory smoke, blue smoke, or the genie) is a humorous name for the caustic smoke produced by severe Failure of electronic components#Electrical overstress, electrical over-stress of electronic circuits or components, causing Overheating (electricity), overheating and an accompanying release of smoke. The smoke typically smells of burning plastic and other chemicals. The color of the smoke depends on which component is overheating, but it is commonly blue, grey, or white. Minor overstress eventually results in component failure, but without pyrotechnic display or release of smoke. A power transistor inside a power supply is a frequent culprit for the acrid smoke. The name is a Running gag, running in-joke that started among Electrical engineering, electrical engineers and technicians, which was later adopted by computer programmer, programmers and computer science, computer scientists.

Phlogiston Theory
The phlogiston theory, a superseded scientific theory, postulated the existence of a fire-like element dubbed phlogiston () contained within combustible bodies and released during combustion. The name comes from the Ancient Greek (''burning up''), from (''flame''). The idea of a substance was first proposed in 1667 by Johann Joachim Becher and later put together more formally in 1697 by Georg Ernst Stahl. Phlogiston theory attempted to explain chemical processes such as combustion and rusting, now collectively known as oxidation. The theory was challenged by the concomitant mass increase and was abandoned before the end of the 18th century following experiments by Antoine Lavoisier in the 1770s and by other scientists. Phlogiston theory led to experiments that ultimately resulted in the identification (), and naming (1777), of oxygen by Joseph Priestley and Antoine Lavoisier, respectively. Theory Phlogiston theory states that ''phlogisticated'' substances contain phlo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electronics And Society
Electronics is a scientific and engineering discipline that studies and applies the principles of physics to design, create, and operate devices that manipulate electrons and other electrically charged particles. It is a subfield of physics and electrical engineering which uses active devices such as transistors, diodes, and integrated circuits to control and amplify the flow of electric current and to convert it from one form to another, such as from alternating current (AC) to direct current (DC) or from analog signals to digital signals. Electronic devices have significantly influenced the development of many aspects of modern society, such as telecommunications, entertainment, education, health care, industry, and security. The main driving force behind the advancement of electronics is the semiconductor industry, which continually produces ever-more sophisticated electronic devices and circuits in response to global demand. The semiconductor industry is one of the global ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

FOLDOC
The Free On-line Dictionary of Computing (FOLDOC) is an online, searchable, encyclopedic dictionary of computing subjects. History FOLDOC was founded in 1985 by Denis Howe and was hosted by Imperial College London. In May 2015, the site was updated to state that it was "no longer supported by Imperial College Department of Computing". Howe has served as the editor-in-chief since the dictionary's inception, with visitors to the website able to make suggestions for additions or corrections to articles. Open sourcing The dictionary incorporates the text of other free resources, such as the Jargon File, as well as covering many other computing-related topics. Due to its availability under the GNU Free Documentation License, a copyleft license, it has in turn been incorporated in whole or part into other free content projects, such as Wikipedia.

Jargon File
The Jargon File is a glossary and usage dictionary of slang used by computer programmers. The original Jargon File was a collection of terms from technical cultures such as the MIT Computer Science and Artificial Intelligence Laboratory, MIT AI Lab, the Stanford University centers and institutes#Stanford Artificial Intelligence Laboratory, Stanford AI Lab (SAIL) and others of the old ARPANET Artificial intelligence, AI/Lisp programming language, LISP/PDP-10 communities, including BBN Technologies, Bolt, Beranek and Newman (BBN), Carnegie Mellon University, and Worcester Polytechnic Institute. It was published in paperback form in 1983 as ''The Hacker's Dictionary'' (edited by Guy L. Steele Jr., Guy Steele) and revised in 1991 as ''The New Hacker's Dictionary'' (ed. Eric S. Raymond; third edition published 1996). The concept of the file began with the Tech Model Railroad Club (TMRC) that came out of early TX-0 and PDP-1 hackers in the 1950s, where the term ''hacker'' emerged and the ...

Central Processing Unit
A central processing unit (CPU), also called a central processor, main processor, or just processor, is the primary Processor (computing), processor in a given computer. Its electronic circuitry executes Instruction (computing), instructions of a computer program, such as arithmetic, logic, controlling, and input/output (I/O) operations. This role contrasts with that of external components, such as main memory and I/O circuitry, and specialized coprocessors such as graphics processing units (GPUs). The form, CPU design, design, and implementation of CPUs have changed over time, but their fundamental operation remains almost unchanged. Principal components of a CPU include the arithmetic–logic unit (ALU) that performs arithmetic operation, arithmetic and Bitwise operation, logic operations, processor registers that supply operands to the ALU and store the results of ALU operations, and a control unit that orchestrates the #Fetch, fetching (from memory), #Decode, decoding and ...

Red Hat Linux
Red Hat Linux was a widely used commercial open-source Linux distribution created by Red Hat until its discontinuation in 2004. Early releases of Red Hat Linux were called Red Hat Commercial Linux. Red Hat published the first non-beta release in May 1995. It included the Red Hat Package Manager as its packaging format, and over time RPM has served as the starting point for several other distributions, such as Mandriva Linux and Yellow Dog Linux. In 2003, Red Hat discontinued the Red Hat Linux line in favor of Red Hat Enterprise Linux (RHEL) for enterprise environments. Fedora Linux, developed by the community-supported Fedora Project and sponsored by Red Hat, is a free-of-cost alternative intended for home use. Red Hat Linux 9, the final release, hit its official end-of-life on April 30, 2004, although updates were published for it through 2006 by the Fedora Legacy project until the updates were discontinued in early 2007.

Smoke Testing (electrical)
Smoke testing refers to various classes of tests of systems, usually intended to determine whether they are ready for more robust testing. The expression probably was first used in plumbing in referring to tests for the detection of cracks, leaks or breaks in closed systems of pipes.Stevenson, Thomas. A Treatise on Hygiene and Public Health, Volume 1'. J. & A. Churchill. 1892, p. 776. By metaphorical extension the term is used in electronics. In ''Lessons Learned in Software Testing'', Cem Kaner, James Bach, and Brett Pettichord provided the origin of the term: "The phrase ''smoke test'' comes from electronic hardware testing. You plug in a new board and turn on the power. If you see smoke coming from the board, turn off the power. You don't have to do any more testing."Kaner, Bach, and Pettichord. ''Lessons Learned in Software Testing''. Wiley Computer Publishing, 2002, p. 95. In electronics and electrical engineering In electronics and electrical engineering, the term smoke ...
