I could not find any information on Scheme so I followed the above link to LISP. LISP may be easy, old and boring to you computer guys but the linked book is not very friendly for a mechanic to figure out. I went off to my local library and found a simple looking book to learn how to program Ruby. I don't know what Ruby is used for, but the instructions are so good I was declaring variables and watching the results in a few hours.
My ultimate goal is to learn what those css scripts do. The ruby book gives me nice instructions on how to install, find and use an interpreter. Hopefully, I will understand some of this persian when I am done. Maybe then, I will be able to write a script to have my photo pages load automatically.
