I have put my collection of Quotations for Learning and Programing on the web. I hope to continue expanding
(and correcting) it. I always welcome feedback (e.g., corrections, misattributions, other quotations).

I am starting to index, annotate, and put on the web various Education-Related Video Clips.

I'll be in class (lecture/yellow) MWF and will hold office hours (gray) for a few hours each day.

Please note that my office hours are open. There is no need to schedule an appointment ahead of time. Just drop by.

If you want debugging help during my office hours, please ensure that your programming project is stored somewhere that we can
download it from, or you have it on a USB memory drive (or, just bring it loaded on your portable computer).

For Office Hours* (with a *) I will sometimes have to cancel because of faculty meetings.
I will send email that day if I cannot attend these office hours.

Interesting Snippets

While developing a manuscript for a textbook on the Ada programming language in the late 1980s, I wrote a chapter on EBNF and began teaching it on the "first" day of my CS-1 class: primarily as a microcosm of programming, but also as a practical tool for later describing the syntax of Ada. These 21 pages (less than 1/4 the size of the original Karel book) discuss the sequence, choice, option, repetition, and recursion control structures (along with "procedural" abstracton via named EBNF rules). They explore various methods of proving that tokens satisfy descriptions, that descriptions are equivalent (and how to simplify them), and the difference between syntax and semantics. I have continued to use this approach until this day in my CS-1 classes. In fact, I have rewritten this EBNF chapter for an introduction to Python course I am teaching.

An excerpt from the chapter "He Fixes Radios by Thinking!" from the book "Surely You're Joking, Mr. Feynman!": Adventures of a Curious Character (start at the bottom of page 18: "One day I got a telephone call..." and finish at the bottom of page 20: "...never thought that was possible.") Explains why debugging is best accomplished by thinking, not fiddling.

Philosphical Musings

Doubts are such tiny things. A mind with no room for doubts must have no room for thoughts either. -R. Pattis

The following dialog is from the transcript of "Between Time and Timbuktu" (a synthesis of the writings of Kurt Vonnegut). For more on Bokononism, from which this passage is inspired, see The Books of Bokonon (from the novel "Cat's Cradle").

Narrator: In the beginning, G-d created the Earth, and he said, "Let there be mud." And there was mud. And G-d said, "Let Us make living creatures out of mud, so the mud can see what We have done." And G-d created every living creature that now moveth, and one was man. Mud-as-man alone could speak. "What is the purpose of all this?" man asked politely. "Everything must have a purpose?" asked G-d. "Certainly," said man. Then I leave it up to you to think of one for all of this," said G-d. And he went away.

Stony Stevenson: I feel very unimportant compared to you [G-d].

Voice of Bokonon: The only way you can feel the least bit important is to think of all the mud that didn't even get to sit up and look around.

SS: I got so much, and most mud got so little.
