Installing tmux-256color for macOS

macOS has ncurses version 5.7 which doesn't ship the terminfo description for tmux. There're two ways that can help you to solve this problem.

The Fast Blazing Solution

Instead of tmux-256color you can use screen-256color, place this command into your ~/.tmux.conf.

set-option -g default-terminal "screen-256color"

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

		## Type Options ##
		## "path" is blue, "success" is green, "failed" is red, "node" is yellow, "blue" is itteration, True is white, False does not create an image ##	
	
		## THIS DETERMINES IF A PATH HAS BEEN FOUND AND WHAT IT IS IF IT HAS FOUND A PATH ##
		self.pathFound = ["none"]
		## KEEPS PATH FINDER LOOKING AS LONG AS THERE IS AN OPEN PATH OPTION ##
		self.pathFoundViable = True
		self.unit = unit

Programming Media Keys on the Ducky One 2 Skyline

To use media keys on the Ducky One 2 Skyline, you must record a macro to bind the media function to a hotkey combination, i.e. Fn plus some key.

Example

Important: In the instructions below, "Press X+Y+Z" means press and hold key X, press and hold key Y, press and hold key Z in that order, and then release all three.

As an example, to bind Fn+PgUp to the play/pause media function:

class MyPanel(wx.Panel):
    def __init__(self, parent):
