OPL2


Oct 3, 2020

I’ve been working on OPL2 code for a while now. I’ve started to understand at a level beyond what I could a few years ago. This is progress. What does it mean? Let’s discuss problem-solving in the context of OPL2 in 2020. I want to write a piece of software for the Intel X86 architecture. I want it to be below the kernel of the computer meaning that there is no operating system, no bootloader and if you’re really wild, only a single function needed from the BIOS. I wrote all this and there are bugs, but instead of focusing on those bugs, we’re instead going to look at just OPL2.

If I were to get this code working on a host machine, our process of problem-solving would actually be a lot easier. Write more code and fix anything that comes up. Because testing on a host is one step more difficult than testing on a VM, I decided that most people would choose to use a VM instead of running my game on their host or a random piece of ancient hardware they have in storage. It is true of me, but I have an excuse. There is a debugger for my VM, Qemu but there is not one in my game’s kernel. That comes in mighty handy when things go wrong.

My research into polynomials has led to a 3x3 captcha solver today. It's very fast. My next attempt will be a 6x6 captcha solver.

Rather than discuss something important or release something interesting, I thought I'd release a piece of non-music audio for the purpose of demonstrating a new breakthrough I've made in sample production and artificial intelligence research. I have automated the process of creating samples based on polynomials. It's a very streamlined process which has produced the below samples. They aren't meant to be musical, so don't complain. Also their volume is way too high so you should turn down your volume before listening to them.

Each are 6 minutes long and it's pretty obvious what the theme is. It doesn't change drastically. That's because it's not music. What is shows is a simple algorithm.
