Installing Linux on the Chuwi Vi8

This gist is a work in progress with various tips and bits of information designed to aid anyone in trying to get linux working on their Chuwi Vi8.

NOTE: As of yet, none of the information has been CONFIRMED by myself!!! I will be providing links that point to all the resources where other users have reported certain things to be working. This disclaimer will be removed once I test and confirm everything.

Support

This project aims to get Arch Linux running on the device with wifi and touch working. Other priorities can be added through requests.

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

	Lisp interpreter in 90 lines of C++

	I've enjoyed reading Peter Norvig's recent articles on Lisp. He implements a Scheme interpreter in 90 lines of Python in the first, and develops it further in the second.

	Just for fun I wondered if I could write one in C++. My goals would be

	1. A Lisp interpreter that would complete Peter's Lis.py test cases correctly...
	2. ...in no more than 90 lines of C++.

	Although I've been thinking about this for a few weeks, as I write this I have not written a line of the code. I'm pretty sure I will achieve 1, and 2 will be... a piece of cake!
