Notes: ^A In the 2.4 GHz bands bonded 40 MHz channels are uniquely named by the primary and secondary 20 MHz channels, e.g. 9+13. In the 5 GHz bands they are denoted by the center of the wider band and the primary 20 MHz channel e.g. 42[40] ^B In the US, 802.11 operation on channels 12 and 13 is allowed under low power conditions. The 2.4 GHz Part 15 band in the US allows spread-spectrum operation
"Least surprise" redirects here. For the principle of least surprise in the Bayesian brain hypothesis, see free energy principle and Bayesian approaches to brain function. In user interface design and software design,[1] the principle of least astonishment (POLA), also known as principle of least surprise,[a] proposes that a component of a system should behave in a way that most users will expect
The bus factor is a measurement of the risk resulting from information and capabilities not being shared among team members, derived from the phrase "in case they get hit by a bus". It is also known as the bus problem, truck factor,[1] or bus/truck number.[citation needed] The concept is similar to the much older idea of key person risk, but considers the consequences of losing key technical exper
HTTP pipelining is a feature of HTTP/1.1, which allows multiple HTTP requests to be sent over a single TCP connection without waiting for the corresponding responses.[1] HTTP/1.1 requires servers to respond to pipelined requests correctly, with non-pipelined but valid responses even if server does not support HTTP pipelining. Despite this requirement, many legacy HTTP/1.1 servers do not support pi
The motherboard of an HP Z820 workstation with two CPU sockets, each with their own set of eight DIMM slots surrounding the socket. Non-uniform memory access (NUMA) is a computer memory design used in multiprocessing, where the memory access time depends on the memory location relative to the processor. Under NUMA, a processor can access its own local memory faster than non-local memory (memory lo

"Chomsky's Universal Grammar" redirects here. For the book, see Chomsky's Universal Grammar: An Introduction. Noam Chomsky is usually associated with the term universal grammar in the 20th and 21st centuries. Universal grammar (UG), in modern linguistics, is the theory of the innate biological component of the language faculty, usually credited to Noam Chomsky. The basic postulate of UG is that th
Logic (from the Ancient Greek: λογική, romanized: logikḗ) is the systematic study of the form of valid inference, and the most general laws of truth. A valid inference is one where there is a specific relation of logical support between the assumptions of the inference and its conclusion. In ordinary discourse, inferences may be signified by words such as therefore, thus, hence, ergo, and so on. T
The English language was introduced to the Americas by the arrival of the British, beginning in the late 16th and early 17th centuries. The language also spread to numerous other parts of the world as a result of British trade and settlement and the spread of the former British Empire, which, by 1921, included 470–570 million people, about a quarter of the world's population. In England, Wales, Ir
HTTP Strict Transport Security (HSTS) is a policy mechanism that helps to protect websites against man-in-the-middle attacks such as protocol downgrade attacks[1] and cookie hijacking. It allows web servers to declare that web browsers (or other complying user agents) should automatically interact with it using only HTTPS connections, which provide Transport Layer Security (TLS/SSL), unlike the in
The JobScheduler is an open-source computer application for enterprise-level scheduling and process automation. It is used to launch executable files and shell scripts and to automatically run database procedures. The JobScheduler stores status and historical information in a backend database management system. All features of the JobScheduler can be used under the GPL license. A commercial licens

In computer programming, a green thread is a thread that is scheduled by a runtime library or virtual machine (VM) instead of natively by the underlying operating system (OS). Green threads emulate multithreaded environments without relying on any native OS abilities, and they are managed in user space instead of kernel space, enabling them to work in environments that do not have native thread su
gPXE is an open-source Preboot eXecution Environment (PXE) client firmware implementation and bootloader derived from Etherboot. It can be used to enable computers without built-in PXE support to boot from the network, or to extend an existing client PXE implementation with support for additional protocols. While standard PXE clients use TFTP to transfer data, gPXE client firmware adds the ability
In functional programming, continuation-passing style (CPS) is a style of programming in which control is passed explicitly in the form of a continuation. This is contrasted with direct style, which is the usual style of programming. Gerald Jay Sussman and Guy L. Steele, Jr. coined the phrase in AI Memo 349 (1975), which sets out the first version of the Scheme programming language.[1][2] John C.
