Golang least squares method: traditional and minimizing sum of squares of perpendicular lengths approach.

	/*
	Код взят отсюда и доработан
	https://gist.github.com/ota42y/db4ff0298d9c945cd261

	Код применим только для y = ax + b
	Для вертикальных прямых неприменим.

	Least Squares Fitting: Perpendicular Offsets
	Мы используем продвинутую версию метода наименьших квадратов, где меряется расстояние перпендикуляра до прямой

An example of using state in Rust

	#![allow(unused)]

	use std::collections::HashMap;

	struct Locked;
	struct Unlocked;

	// PasswordManager<Locked> != PasswordManager<Unlocked>

	struct PasswordManager<State = Locked> {

Achieving warp speed with Rust

	I expected the first configuration below, simple.conf, to work just fine.

	But it doesn't. My app server receives the second hit with the same URI as the first hit.

	On the second config, wtf.conf, I keep the original URL on a variable to use in the error redirect.

	My question is this: why doesn't the first simple.conf configuration works?
