Modes

Vim has two modes insertion mode and command mode. The editor begins in command mode, where the cursor movement and text deletion and pasting occur. Insertion mode begins upon entering an insertion or change command. [ESC] returns the editor to command mode (where you can quit, for example by typing :q!). Most commands execute as soon as you type them except for "colon" commands which execute when you press the ruturn key.

Quitting

• :x Exit, saving changes
  
• :q Exit as long as there have been no changes
  
• ZZ Exit and save changes if any have been made
  
• :q! Exit and ignore any changes

Vim Cheat Sheet

Vim is an advanced CLI based text editor. Many key combinations used in Vim are easily associated with a memorable phrase. One effective way to use Vim is to associate phrases with Operators, Text Objects and Motions. Then compose a phrase for what you want to do. Start with an Operator followed by a Text Object or Motion. Prefix an Operator, Command or Motion with a number/count to extend it.

Table of Contents

• Modes
• Operators
• Motions
  • Left-Right Line Motions
  • Up-Down Motions
• Word Motions

High-Performance Matrix Multiplication

This is a short post that explains how to write a high-performance matrix multiplication program on modern processors. In this tutorial I will use a single core of the Skylake-client CPU with AVX2, but the principles in this post also apply to other processors with different instruction sets (such as AVX512).

Intro

Matrix multiplication is a mathematical operation that defines the product of
