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

Be Careful with Table Driven Tests and t.Parallel()

We Gophers, love table-driven-tests, it makes our unittesting structured, and makes it easy to add different test cases with ease.

Let’s create our table driven test, for convenience, I chose to use t.Log as the test function. Notice that we don't have any assertion in this test, it is not needed to for the demonstration.

func TestTLog(t *testing.T) {
	t.Parallel()

Setting up netboot.xyz with an EdgeRouter

This document covers how to setup netboot.xyz, a service that provides iPXE-based installation and live boot of a bunch of operating systems, on a Ubiquiti EdgeRouter.

Assumptions

I've made a few assumptions throughout this document that will probably be different for your setup:

Understanding Kubernetes in 10 minutes

Original document can be found here; written by Mike Schuette.

This document provides a rapid-fire overview of Kubernetes concepts, vocabulary, and operations. The target audience is anyone who runs applications in a cloud environment today, and who wants to understand the basic mechanics of a Kubernetes cluster. The goal is that within 10 minutes, managers who read this should be able to listen in on a Kubernetes conversation and follow along at a high level, and engineers should be ready to deploy a sample app to a toy cluster of their own.

This orientation doc was written because the official Kubernetes docs are a great reference, but they present a small cliff to climb for newcomers.

If you want to understand why you should consider running Kubernetes, see the official Kubernetes conceptual overview document. This doc

Generating Authy passwords on other authenticators

---

*update: TBC, but this new might affect how easy it is to use this technique past August 2024: Authy is shutting down its desktop app | The 2FA app Authy will only be available on Android and iOS starting in August

---

This gist, based in part on a gist by Brian Hartvigsen, allows you to export from Authy your TOTP tokens you have stored there.
Those can be "standard" 6-digits / 30 secs tokens, or Authy's own version, the 7-digits / 10 secs tokens.
