LaTeX is a programming language used primarily for creating high quality academic written documents, slideshows and posters. LaTeX questions are often a better fit for the sister site "TeX - LaTeX" (https://tex.stackexchange.com). This includes questions on tools and other languages producing LaTeX code. The JavaScript libraries MathJax and KaTeX are off-topic on "TeX - LaTeX" and should be asked on Stack Overflow instead (and tagged accordingly).

Abbreviation for Global Positioning System; a navigational system using satellite signals to fix the location of a radio receiver on or above the earth's surface. Also "GPS" refers to the radio receiver used to receive GPS signals.

A UserControl is a separate, reusable input control that allows a user to interact with an application. User controls can be buttons, checkboxes, input text boxes, mice, keyboards, etc.

"subquery" is vague SQL terminology, used to describe when there's either more than one `SELECT` statement in a query, or when used in Data Manipulation Language (DML) statements (IE: DELETE, UPDATE, INSERT, MERGE). The subquery's SELECT statement is always found within brackets/parenthesis.

Iterations are the successive repetitions in loops such as for, foreach or while. Questions with this tag are often concerned about how to best handle a collection of data.

g++ is the C++ frontend to the GNU Compiler Collection (GCC). It's the de facto standard compiler for C, C++, Go, Fortran, and Ada on Linux and supports many other languages and platforms as well. Apart from the compiler, GCC has a toolchain (libc, libstdc++, objdump, nm etc.) that is widely used on several platforms and systems.

A container is a class, a data structure, or an abstract data type whose instances are collections of other objects. Containers typically make use of generics or templates so that a wide variety of objects can be added.

The WiX Toolset (formerly known as Windows Installer XML) is a toolset that builds Windows installation packages and WiX bootstrappers from XML source code. The toolset supports a command line environment that developers may integrate into their build processes to build MSI and MSM setup packages and EXE bootstrappers. For the cloud-based web development platform, use the [velo] tag.

Constants in programming are definitions whose value is fixed throughout a program's execution. Literals in most languages are constants, for example. In referentially transparent programming styles, all definitions are constant. A const-qualified data storage area (object, field, variable, parameter) is one that "never changes", thus allowing extra code generator optimizations and additional static checking of program correctness.

Mono is an open source implementation of .NET that runs on many platforms, including Linux, Mac OS X, and Windows. This allows running .NET applications on platforms other than Windows with little to no modification.

ADO.Net is commonly used by programmers to access and modify data stored in relational database systems, though it can also access data in non-relational sources. It is a part of the base class library that is included with the Microsoft .NET Framework.
