C# to Rust Cheat Sheet

The goal of this is to have an easily-scannable reference for the most common syntax idioms in C# and Rust so that programmers most comfortable with C# can quickly get through the syntax differences and feel like they could read and write basic Rust programs.

What do you think? Does this meet its goal? If not, why not?

Variables

Running Time:

The number of (primitive) operations an algorithm performs before coming to a halt. The running time is expressed as a function of the input size n.
Three Methods (of many) of solving recurrence relations:
- Master method
  - T(n) = aT(n/b) + n^d where a >= 1, b > 1
    - n is the size of the problem.
    - a is the number of subproblems in the recursion.
n/b is the size of each subproblem

Chapter 17 - Parallel Processing

General Organization

Four types of organization
SISD
- Single Instruction, Single Data stream
- Single processor executes a single instruction stream to operate on data stored in a single memory.
- Examples: Uniprocessors
SIMD
Single Instruction, Multiple Data stream

Emacs packages, features, files, layers, extensions, auto-loading, require, provide, use-package… All these terms getting you confused? Let’s clear up a few things.

Files

Emacs files contains code that can be evaluated. When evaluated, the functions, macros and modes defined in that file become available to the current Emacs session. Henceforth, this will be termed as loading a file.

One major problem is to ensure that all the correct files are loaded, and in the

	`emacs --daemon` to run in the background.
	`emacsclient.emacs24 <filename/dirname>` to open in terminal

	NOTE: "M-m and SPC can be used interchangeably".

	* Undo - `C-/`
	* Redo - `C-?`
	* Change case: 1. Camel Case : `M-c`
	2. Upper Case : `M-u`
	3. Lower Case : `M-l`
