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).
Matrix multiplication is a mathematical operation that defines the product of

I am passionate about Ruby, but its execution time compared to other languages is extremely high, especially when we want to use more complex algorithms. In general, data structures in interpreted languages become incredibly slow compared to compiled languages. Some algorithms such as ´n-body´ and ´fannkuch-redux´ can be up to 30 times slower in Ruby than Go. This is one of the reasons I was interested in embedding Go code in a Ruby environment.
For those who do not know how shared libraries operate, they work in a similar way as DLLs in Windows. However, they have a native code with a direct interface to the C compiler.
Note Windows uses the DLL system, and in this case, this does not necessarily have to be in native code.
One example is DLLs written in C#, which runs on a virtual machine. Because I do not use windows, I ended up not testing if it is poss
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()
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.
I've made a few assumptions throughout this document that will probably be different for your setup:
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
Past August 2024, Authy stopped supported the desktop version of their apps:
See Authy is shutting down its desktop app | The 2FA app Authy will only be available on Android and iOS starting in August for details.
And indeed, after a while, Authy changed something in their backend which now prevents the old desktop app from logging in. If you are already logged in, then you are in luck, and you can follow the instructions below to export your tokens.
If you are not logged in anymore, but can find a backup of the necessary files, then restore those files, and re-install Authy 2.2.3 following the instructions below, and it should work as expected.
