knowledge dump on container runtimes

KataContainers
- image coupled with kernel 
- light vm layer
- can run in nested virturalization environments if hardware supports and you can enable it in bios (ex. only bare metal EC2 instances, limits many cloud providers)
- slower startup time
- OCI compliant
- previously known as ClearContainers by Intel

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

C++'s Templates

C++'s templates could be seen as forming a duck typed, purely functional code generation program that is run at compile time. Types are not checked at the initial invocation stage, rather the template continues to expand until it is either successful, or runs into an operation that is not supported by that specific type – in that case the compiler spits out a 'stack trace' of the state of the template expansion.

To see this in action, lets look at a very simple example:

template
