It is a subset of the Linux kernel, intended for 16-bit computers with limited processor and memory resources such as machines powered by Intel 8086 and compatible microprocessors not supported by 32-bit Li... |
https://en.wikipedia.org/wiki/Event%20%28computing%29 | In programming and software design, an event is an action or occurrence recognized by software, often originating asynchronously from the external environment, that may be handled by the software. Computer events can be generated or triggered by the system, by the user, or in other ways. Typically, events are handled ... |
https://en.wikipedia.org/wiki/Ultra-linear | Ultra-linear electronic circuits are those used to couple a tetrode or pentode vacuum-tube (also called "electron-valve") to a load (e.g. to a loudspeaker).
'Ultra-linear' is a special case of 'distributed loading'; a circuit technique patented by Alan Blumlein in 1937 (Patent No. 496,883), although the name 'distribu... |
https://en.wikipedia.org/wiki/Deterministic%20context-free%20language | In formal language theory, deterministic context-free languages (DCFL) are a proper subset of context-free languages. They are the context-free languages that can be accepted by a deterministic pushdown automaton. DCFLs are always unambiguous, meaning that they admit an unambiguous grammar. There are non-deterministi... |
https://en.wikipedia.org/wiki/PhishTank | PhishTank is an anti-phishing site.
PhishTank was launched in October 2006 by entrepreneur David Ulevitch as an offshoot of OpenDNS. The company offers a community-based phish verification system where users submit suspected phishes and other users "vote" if it is a phish or not. OpenDNS was acquired by Cisco and in t... |
https://en.wikipedia.org/wiki/Leonardo%20Chiariglione | Leonardo Chiariglione () (born 30 January 1943 (age ) in Almese, Turin province, Piedmont, Italy) is an Italian engineer who has led the development of international technical standards for digital media. In particular, he was the chairman of the Moving Picture Experts Group (MPEG) from 1988 to 2020, which he co-founde... |
https://en.wikipedia.org/wiki/Excitation%20table | In electronics design, an excitation table shows the minimum inputs that are necessary to generate a particular next state (in other words, to "excite" it to the next state) when the current state is known. They are similar to truth tables and state tables, but rearrange the data so that the current state and next stat... |
https://en.wikipedia.org/wiki/Ground%20pressure | Ground pressure is the pressure exerted on the ground by the tires or tracks of a motorized vehicle, and is one measure of its potential mobility, especially over soft ground. It also applies to the feet of a walking person or machine. Pressure is measured in the SI unit of pascals (Pa). Average ground pressure can b... |
https://en.wikipedia.org/wiki/Coding%20conventions | Coding conventions are a set of guidelines for a specific programming language that recommend programming style, practices, and methods for each aspect of a program written in that language. These conventions usually cover file organization, indentation, comments, declarations, statements, white space, naming conventio... |
https://en.wikipedia.org/wiki/Ppc64 | ppc64 is an identifier commonly used within the Linux, GNU Compiler Collection (GCC) and LLVM open-source software communities to refer to the target architecture for applications optimized for 64-bit big-endian PowerPC and Power ISA processors.
ppc64le is a pure little-endian mode that has been introduced with the PO... |
https://en.wikipedia.org/wiki/Sequential%20probability%20ratio%20test | The sequential probability ratio test (SPRT) is a specific sequential hypothesis test, developed by Abraham Wald and later proven to be optimal by Wald and Jacob Wolfowitz. Neyman and Pearson's 1933 result inspired Wald to reformulate it as a sequential analysis problem. The Neyman-Pearson lemma, by contrast, offers a ... |
https://en.wikipedia.org/wiki/NUN%20buffer | NUN buffer is a solution that makes it possible to purify proteins located in the nucleus of eukaryotic cells. Although other procedures are available they result in loss of albumin D-box binding protein (DBP) which is unwanted if nuclear signal pathways are to be investigated. Therefore, a new extraction procedure was... |
