Rust Cheat Sheet

Variables & Mutability

Variables are immutable by default. This makes Rust safer and makes concurrency easier.
Immutable means once a value is bound to that variable, it cannot be changed.
For example:

fn main() {
 let x = 5;

WORK IN PROGRESS

Docker on Android

Setup:

Samsung Galaxy Tab S5e SM-T720
Android Pie on Linux 4.9.112 (not rooted)
Termux

Common Options

-#, --progress-bar Make curl display a simple progress bar instead of the more informational standard meter.

-b, --cookie <name=data> Supply cookie with request. If no =, then specifies the cookie file to use (see -c).

-c, --cookie-jar <file name> File to save response cookies to.

Virtual Hosts on nginx (CSC309)

When hosting our web applications, we often have one public IP address (i.e., an IP address visible to the outside world) using which we want to host multiple web apps. For example, one may wants to host three different web apps respectively for example1.com, example2.com, and example1.com/images on the same machine using a single IP address.

How can we do that? Well, the good news is Internet browsers

	Инструкция по использованию:
	- Заходим в раздел с аудиозаписями
	- Листаем в самый низ (Чтобы прогрузились все аудиозаписи) (Можно зажать клавишу PageDown)
	- Открываем консоль браузера (F12 -> Консоль)
	- Вставляем код и нажимаем Enter
	- Скачивание началось...
	- Браузер может потребовать разрешение на сохранение файлов, необходимо подтвердить действие
	- Оставляем браузер на время прямо пропорциональное количеству аудиозаписей :)
