This is an extension of Python's "Meta: Documentation Guidelines" for Django. These are just proposals, not recommendations. Feel free to edit anything here if you disagree or have something else to mention.

While Django is primarily for web apps it has a powerful and easy to use ORM that can be used for command line apps and scripts too. There are two different approaches that can be used. The first being to create a custom management command and the second to initialize the Django environment at the...
Explain why certain things are marked unsafe in Rust, and why we might need to use this escape hatch in certain (rare) situations.
#![feature(asm)] // Enable the asm! macro feature gate asm!(<template> : <output> : <input> : <clobbers> : <options>) // Emit the assembly template provided (e.g. "NOP", "ADD %eax, 4") with the given options.
Rust's standard library does not contain a proper argument parser (unlike argparse in Python), instead preferring to leave this to third-party crates. These examples will show the usage of both the standard library (to form a crude argument handler) and the clap library which can parse command-l...
A function defined with the inline specifier is an inline function. An inline function can be multiply defined without violating the One Definition Rule, and can therefore be defined in a header with external linkage. Declaring a function inline hints to the compiler that the function should be inli...
Line drawing is accomplished by calculating intermediate positions along the line path between two specified endpoint positions. An output device is then directed to fill in these positions between the endpoints.
Theory Definition 1: An optimization problem Π consists of a set of instances ΣΠ. For every instance σ∈ΣΠ there is a set Ζσ of solutions and a objective function fσ : Ζσ → ℜ≥0 which assigns apositive real value to every solution. We say OPT(σ) is the value of an optimal solution, A(σ) is the s...
