You might try that. Or you can try viewing the videos on YouTube: http://www.youtube.com/watch?v=qNg3XXvgTdQ http://www.youtube.com/watch?v=hCmBhFXWjl0 I’m not terribly familiar with noscript but I seem to recall there’s a “temporarily allow access to this site” option?

Hard to see the words on the board and I thought Prof. Eadline might just "mark" out if he kept sniffing those pens. Still didn't get what "concurrent" is from these videos. Sure, it's a property of the process/algorithm. However, "sweet" is a property of candy but just saying that really doesn't define what "sweet" is. For me, concurrency is the property of the algorithm where one or more things can be "in progress" at the same time (writing separate sentences of the lab report); parallel is when things are "executing" at the same time (having 100 people each writing a sentence at the same time). Thus, parallel is a subset of concurrent (that requires hardware support). Just saying that concurrent does not imply parallel is a tad misleading, in my book, especially if you only have one specific example. Look for "A visual guide to key concepts in threaded programming – Common problems and how to solve them" for a low tech, higher energy presentation of paralell/concurrent topics.
