When learning the piano or other musical instruments, it is necessary to do regular finger exercises to get various chords, movements, and styles into ones brain. Then even after you have mastered the instrument, you will find that regular returning to the exercises are needed to keep your skills fresh, or to warm up to a larger engagement.
After many years of doing different coding in short bits, I believe the same is with coding. While I have 'learned' many different languages over the years, I have also not focused on many of them for very long. I had also come to realize I have bought many books over the time, done some of the exercises here and there, but not fully focused on them. So this project is meant to work through some of those books examples and exercises to get some of the rust off the mental blade.
Since many of these are short works taken from books, the licensing of the 'code' involved is difficult. I will endeavor to make sure that segments copied from verbatum have the book, page and authors listed.
