In an earlier post, I recommended that everyone who uses computers should read Linus Torvald and David Diamond's book Just For Fun: The Story of an Accidental Revolutionary. I also think that folks should read something about Richard Stallman, the father of GNU (GNU's Not Unix) Operating System. Technically, it was Richard Stallman's work and Linus Torvald's work that when combined created what is popularly known as Linux.
John Sedgwick recently interviewed Richard Stallman for the May 2008 issue of Boston Magazine. The result was The Shaggy God. The article is easy to read and provides a few references to the history of Free and Open Source Software. It also gives a glimpse into the life and inklings of the thinking of an extremely bright revolutionary visionary. The little I've read of Richard Stallman causes me to anticipate that he is passionate, intense, and highly technical and exacting in both his personal and professional conversations. I think it would be an interesting experience to hear him speak and/or present.
I'm not sure that people like Stallman and Torvalds understand and appreciate people who are merely end-users of their systems. However, end-users are the ones who can make a difference in the world. Stallman and Torvalds are loners. Most end-users are not loners. They use technology as a social network. The philosophy that Stallman and Torvalds espouse is one that end-users can begin to understand and embrace and share as they use Open Source software.

Linus Torvalds
The family spent a cold Maine afternoon browsing at our local Borders. (I know, local and Borders is an oxymoron.) I collected a diversity of books to peruse while having a cup of something warm. My pile included texts on low-fat vegan recipes (a GREAT way to lose weight!), knitting, Barack Obama, and Linux. Of the four books on Linux I chose to peruse, only one was non-techie friendly. I ended up buying it because it is an AMAZING story. Just For Fun: The Story of an Accidental Revolutionary by Linus Torvalds and David Diamond is readable, insightful, and fun. The authors even warn you when there is a significantly technical section between pages 39-119. It is technical but if you can read for the story and not for understanding every technical detail you can get a lot out of this section. This memoir of Linus Torvalds' makes the image of a technogeek human. Anyone who uses computers in any fashion should read this story to gain insight into this world.
I was especially struck by one particular section last night and shared it with my class of second-graders this morning. The section is V in Birth of an Operating System. In this section, Linus Torvalds explains how programming can be beautiful. My liberal arts mind was sceptical but I read on and TA DA! I got it! A possible apocryphal story is related about a German math class that had Carl Friedrich Gauss ( a future mathematician) as a student. The teacher was bored and supposedly assigned his students the task of adding up all the numbers from 1 to 100. The teacher assumed this would take a very long time. Gauss reportedly solved the problem in 5 minutes. How did he do this? By recognizing the pattern and using it!
At circle this morning, (I like to gather my students close for big learnings. Learning becomes personal that way and I can engage everyone.) I wrote on the dry erase board.
"Mathematics is recognizing patterns and using them.
There is always a hard way and an easy way to solve a problem.
~Add the numbers 1, 2, 3, 4, 5, 6, 7, 8, 9, 10
~What's the answer?
~How did you figure it out?"
Then I told my class about my trip to Borders and how I couldn't find any books on teaching with Linux but I did find Just For Fun: The Story of an Accidental Revolutionary by Linus Torvalds and David Diamond. I told them a teensy bit about Mr. Torvalds and made a connection between him and the K12LTSP workstations in our classroom. We read the dry erase board aloud. One student said, "Oh, so you add 10 + 9 + 8 + 7 + 6 + 5 + 4 + 3 + 2 + 1." Another student blurted, "It's 54!" Before the blurting got out of hand, I wrote out 10 + 9 = 19 + 8 =etc. with the class supplying the answers. Obviously, we calculated 55. Then I asked them if they thought that this was the easy way or the hard way. They all answered "hard". I asked what the easy way would be and a girl who had been relatively quiet up til now said, "There must be a pattern . . .what could it be . . .?" The class already knew that adding can be done in any direction so I asked them to use that idea to look for a pattern. My quiet girl's eyes lit up with excitement. She was babbling so fast, the rest of the class didn't get what she was saying. So I had to write it out for the class~1 + 10 = 11, 2 + 9 = 11, etc and you end up with 5 11's to add up. We tried it with adding up the numbers to 50 and with adding up the numbers to 200. We did use a calculator to do the last bit of math since we haven't quite gotten to multiplication yet but the rest was mental calculations. It was an exciting teaching moment for the class and for me. My quiet student probably got far more out of it than the other students but they got to hear and experience a new idea. We'll go back and look at that idea again and again.
In the meantime, get a copy of Just For Fun: The Story of an Accidental Revolutionary by Linus Torvalds and David Diamond from your local library or your local bookstore. It's well worth reading.
