A stencil is a template used to draw or paint identical letters, symbols, shapes, or patterns every time it is used. The design produced by such a template is also called a stencil.

The Stencil Subtractor frame was a ciphered text recyphering tool that was invented by British Army Intelligence Officer and cryptographer John Tiltman and was ready for trial by April 1941 but was not adopted officially by the British Forces until March 1942, and not brought into service until June 1943. It was used together with Subtractor tables, placed on top of the table and the numerical values visible in the gaps of the SS Frame were used to encipher the underlying numerical code, for example the War Office Cipher, RAF cipher or Naval cipher. The SSF was described as follows: "consisting of a plastic grille that contained 100 4-digit wide windows randomly spaced. This was superimposed over an additive sheet that had forty-eight lines of sixty-eight digits each. Setting squares on the grille provided placement for one-hundred possible settings and a conversion table appeared on each sheet with mixed sequences of digits from 00 to 99 for indicating purposes. The placement of the grille was determined through a substitution pattern sent to each user"
Stencil computations, or iterative stencil loops (ISL), are a class of numerical data processing solution which update array elements according to some fixed pattern, called a stencil. They are most commonly found in computer simulations, e.g. for computational fluid dynamics in the context of scientific and engineering applications. Other notable examples include solving partial differential equations, the Jacobi kernel, the Gauss–Seidel method, image processing and cellular automata. The regular structure of the arrays sets stencil techniques apart from other modeling methods such as the finite element method. Most finite difference codes which operate on regular grids can be formulated as stencil computations.
In computer programming, code bloat is the production of executable code (source code or machine code) that is unnecessarily long, slow, or otherwise wasteful of resources. Code bloat can be caused by inadequacies in the programming language in which the code is written, the compiler used to compile it, or the programmer writing it. Thus, while code bloat generally refers to source code size (as produced by the programmer), it can be used to refer instead to the generated code size or even the binary file size.
Before the 1921 destruction of Tulsa’s Greenwood District, Black residents had created a remarkable center of business and community life. The district included stores, professional offices, entertainment venues and homes owned by Black citizens. Understanding Greenwood means learning what was built—not only what was burned.
