This is a list of the hardware, software, and services I used when assembling this book. I found all these tools useful and encourage you to check them out.
My home-office workstation is a Shuttle Cube PC with Intel Core i5 Processor, 8 GB RAM, 1 TB disk space, and a dual monitor (Dell Ultrasharp 21”) setup running XUbuntu 14.4.
When I was on the road, I usually brought along a Lenovo X1 Carbon with Intel Core i5 processor, 4 GB RAM, 128 GB SSD, and a 14” monitor running Windows 8.1 OS.
Occasionally I carry a Google Chromebook Pixel Netbook with me. It has Intel Core i5, 8 GB RAM, 32 GB storage, and a 13” touchscreen.
For this book project, I made a habit of drawing diagrams and flow charts to help me better visualize the ideas in the book. Most of the time I used a simple setup of 3” × 5” unlined note cards and Sharpie-brand Fine Point and Ultra Fine Point pens and then scanned those into the computer. I also occasionally used the LiveScribe3 Smartpen and paper to sketch out my ideas and automatically transfer them to the computer for editing and sharing.
