Here is a quote at the beginning of Chapter 1 written by the author. It reads more like a poem rather than a sentence from a programming book.
Below the surface of the machine, the program moves. Without effort, it expands and contracts. In great harmony, electrons scatter and regroup. The forms on the monitor are but ripples on the water. The essence stays invisibly below. - Master Yuan-Ma, The Book of Programming
Select Speed Limit:
The speed limit sign was created with Inkscape and OpenSignTool. The SVG file has 17 layers for different speed limit numbers from 5 MPH to 85 MPH.
Next step for the app is to add another dropdown control for file formats (SVG, EMF, PNG) and a download button for user to download a file to local computer.
I also referenced those two online articles when working on this blog post.
