Anlog playback control of digital media

This is the basic idea;

• Use a standard D2A algorithm (check out the winmodem source in the linux kernel for instance) to record a sequence of timestamps onto a cassette tape, Compact Disc or even Vinyl record.

• Connect the output of your choosen playback device to audio input of a computer (Raspberry PI).

• Insert your media (casette) into your playback device and start playing.

XPOS            = $07

PATTERN         = $0800; 48 columns * 48 rows * 8 bytes + 48 columns = $4830 bytes
SCALEDBMP       = $8c00; 25 columns * 25 rows * 8 bytes = $1388 bytes

pointer         = $7a
pointer2        = $33
pointer3        = $35
pointer4        = $22

Editor > General > Soft Wraps

• Soft-wrap files: Change to * (or add *.java, *.cpp etc)
• Check "Use original line's indent for wrapped parts"

C++ Developer Guide

Please note; these rules are not random; nor are they my personal preferences. They represent -- for the most part -- an emerging 'de facto' standard for how modern C++ code is developed.

Basics

C++14 "modern" style

JNIEXPORT jlong JNICALL Java_com__getComponent(JNIEnv* env, jclass, jstring name)
{
    std::shared_ptr<Component> component = sm->getComponent(JString{name, env});
    if (!component)
        return 0;
    return (jlong)(new std::shared_ptr<Component>(component));
}

JNIEXPORT void JNICALL Java_com_releaseComponent(JNIEnv*, jclass, jlong component)
{

Always strive for simplicty. Avoid redundancy.

Start writing non generic code, top down, doing just what is needed.

Later, refactor anything that looks like a generic construct and break it out to a separate component. And test it.

Iterate.

How to be productive from the command line

• Optional first step; install iTerm2; https://www.iterm2.com/downloads.html

iTerm2 is more capable than the build int terminal, adding things like Split panes.

• Get Homebrew https://brew.sh/

Now you can install most of the stuff you need using brew install <packagename>
