Chapter 2 reading notes: types and runtime data areas, and a bit about threads. Opcodes will come soon 😄! Source: chapter 2 of JVM specification.

Let’s start small: start by reading the specification’s introduction

Generating a color palette

While playing with p5.js I often stumble upon a problem of color palette choice. The colors that I use in my artictic/programming playground are (usually) randomly generated.
