Terminals should generate the 256-color palette from the user's base16 theme.

If you've spent much time in the terminal, you've probably set a custom base16 theme. They work well. You define a handful of colors in one place and all your programs use them.

The drawback is that 16 colors is limiting. Complex and color-heavy programs struggle with such a small palette.

This document is intended to document certain inner workings of the CPU.

There have been efforts by emu-russia and gekkio to have the CPU decapped, and so we have the decode ROM accessible to us. This means, that we know exactly what each opcode does (besides some nuanced behavior related to HALT, STOP, and some state management related to interrupts and power saving which are hard to untangle).

// Step 1: Obtain Yosys from git.
// Step 2: Download jt51 from https://github.com/jotego/jt51.
// Step 3: Build as follows:
//   $ yosys jt51/hdl/*.v -b 'cxxrtl -header' -o jt51_core.cc
//   $ CFLAGS="-fbracket-depth=2048 -I$(yosys-config --datdir/include)"

Introduction

The following information illustrates the differences between macOS, Windows and Linux in USB device enumeration sequence.

Specifically the comparison covers USB Mass Storage device enumeration, implemented with the TamaGo USB driver on a USB armory Mk II running armory-ums.

Notes on adding Constraint Kinds to Rust

Background: Constraint Kinds

a trait can be thought of as a type operator generating a "constraint" - what in Rust would usually be called a bound. For example:

// Declares a new item `Foo` with kind `type -> constraint`
trait Foo { }
