Amazon Linux 2 - install docker & docker-compose using 'sudo amazon-linux-extras' command
View install-docker.md

UPDATE (March 2020, thanks @ic): I don't know the exact AMI version but yum install docker now works on the latest Amazon Linux 2. The instructions below may still be relevant depending on the vintage AMI you are using.

Amazon changed the install in Linux 2. One no-longer using 'yum' See: https://aws.amazon.com/amazon-linux-2/release-notes/

Docker CE Install

sudo amazon-linux-extras install docker
sudo service docker start

AppleScript and JavaScript for Automation to get frontmost tab’s url and title of various browsers.
View get_title_and_url.applescript
-- AppleScript --
-- This example is meant as a simple starting point to show how to get the information in the simplest available way.
-- Keep in mind that when asking for a `return` after another, only the first one will be output.
-- This method is as good as its JXA counterpart.
-- Chromium variants include "Google Chrome", "Chromium", "Opera", "Vivaldi", "Brave Browser", "Microsoft Edge".
-- Specific editions are valid, including "Google Chrome Canary", "Microsoft Edge Dev".
-- "Google Chrome" Example:
tell application "Google Chrome" to return title of active tab of front window

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
