About the Book
I first wrote xacpi back in 2013, in Python2, after numerous hard shutdowns of my laptop for failing to plug it in; you see, I only use lightweight window managers (fluxbox for the last 15 years or so, and previous xfce) without battery indicators, so I rolled my own (with lots of help online). Lately I came up with a way to turn a github repo into a book, with some help from my friends Grok and DeepSeek, and this is my first of the series "sourcebook".
About the Author
programming computers since 1968 or so, after reading a book on BASIC at the high school library, although I didn't get to test them until getting hands-on the DEC PDP-10 at Worcester Polytechnic Institute (where I only lasted a year due to poor study discipline).
