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

The LambdaConf Ladder of Functional Programming (LOFP) is a standardized progression of different concepts and skills that developers must master on their journey to becoming expert-level functional programmers. LOFP can be used to rank workshops, talks, presentations, books, and courseware, so that aspiring functional programmers have a better understanding of what material is appropriate for them given their current experience.

A function is a mapping from one set, called a domain, to another set, called the codomain. A function associates every element in the domain with exactly one element in the codomain. In Scala, both domain and codomain are types.
val square : Int => Int = x => x * x
It's now here, in The Programmer's Compendium. The content is the same as before, but being part of the compendium means that it's actively maintained.
Below is my understanding of affine types and how they help us in Rust (unsure if I got this right - please correct if I am talking nonsense).
The issue is... How can we use the power of a type system so a compiler will block us from doing this wrong sequence of calls?
FILE *fp = NULL;
fclose(fp);
fp = fopen("...");
An idea is to "mirror" the states that the file variable goes through (unused/closed, opened) in the type system:

Minecraft mods, especially mods which change the client, are by and large written with Forge. If you visit their website, you'll be greeted abruptly by a mysterious message at the top of an SMF forum, with no clear path towards actually... making a mod. I'm documenting here the steps I went through to get started, in the hopes of helping the next person have an easier time of it.
I'll be using Scala for this guide, but it should be fairly easy to adapt these instructions to any JVM language (e.g. clojure or if you're feeling masochistic, Java). I'm also developing on OS X, so some of the commands will be a little different if you're on Linux or Windows. I'm assuming you have some proficiency with your operating system, so I won't go into details about how to adapt those commands to your system.
Minecraft doesn't have an official mod API (despite early [promises](http://notch.t
