A regular expression denial of service (ReDoS)[1] is an algorithmic complexity attack that produces a denial-of-service by providing a regular expression and/or an input that takes a long time to evaluate. The attack exploits the fact that many[2] regular expression implementations have super-linear worst-case complexity; on certain regex-input pairs, the time taken can grow polynomially or expone
This article is about the I/O method. For the vector addressing type, see Gather-scatter (vector addressing). In computing, vectored I/O, also known as scatter/gather I/O, is a method of input and output by which a single procedure call sequentially reads data from multiple buffers and writes it to a single data stream (gather), or reads data from a data stream and writes it to multiple buffers (s
An information silo, or a group of such silos, is an insular management system in which one information system or subsystem is incapable of reciprocal operation with others that are, or should be, related. Thus information is not adequately shared but rather remains sequestered within each system or subsystem, figuratively trapped within a container like grain is trapped within a silo: there may b
Portable Network Graphics (PNG, officially pronounced /pɪŋ/[2][3] PING, colloquially pronounced /ˌpiːɛnˈdʒiː/[4] PEE-en-JEE) is a raster-graphics file format that supports lossless data compression.[5] PNG was developed as an improved, non-patented replacement for Graphics Interchange Format (GIF)—unofficially, the initials PNG stood for the recursive acronym "PNG's not GIF".[6] PNG supports palet

"Ragel 6 remains under GPL v2 [generated code] covered by the MIT (or GPL v2)".[3] Ragel 7: MIT License Ragel is a finite-state machine compiler and a parser generator. Initially Ragel supported output for C, C++ and Assembly source code,[4] and was expanded to support several other languages including Objective-C, D, Go, Ruby, and Java.[5] Additional language support is also in development.[6] It
The structural similarity index measure (SSIM) is a method for predicting the perceived quality of digital television and cinematic pictures, as well as other kinds of digital images and videos. SSIM is used for measuring the similarity between two images. The SSIM index is a full reference metric; in other words, the measurement or prediction of image quality is based on an initial uncompressed o
Worse is better (also called the New Jersey style[1]) is a term conceived by Richard P. Gabriel in a 1989 essay[2] to describe the dynamics of software acceptance. It refers to the argument that software quality does not necessarily increase with functionality: that there is a point where less functionality ("worse") is a preferable option ("better") in terms of practicality and usability. Softwar
Nokia 8110 4G "banana phone" KaiOS is a mobile Linux distribution for keypad feature phones based on the Firefox OS open-source project.[6] It is developed by KaiOS Technologies (Hong Kong) Limited; a company based in Hong Kong, whose largest shareholder is Chinese electronics conglomerate TCL Corporation.[7][1] KaiOS runs on feature phones or wireless home phones made with low-power hardware and
