       * Tech notes:
         * to pass a command line parameter into your ruby program (i.e., so each producer/consumer knows its id), use the ''ARGV'' array like this: <code text> id = ARGV[0]</code>
-        * then use a for loop from the bash prompt to run multiple producers/consumers: <code text> $ for i in {1..3}
+        * then use a for loop from the bash prompt to run multiple producers/consumers: <code text>$ for i in {1..3}
 > do ruby producer.rb $i &
 > done
 </code>
         * and similarly to launch a different number of consumers
+      * Demo: Marc will attempt a live demo running multiple producers and consumers from his version 3 -- hope this works!  LOL\\ \\
+      * Tech notes 2:
+        * alternatively, we could seed TS with producer/consumer id tuples
+          * instead of passing in command line arguments via ''ARGV'' array
+        * then each producer process can ''ts.take'' their producer id tuple, and
+        * each consumer process can do the same for their consumer id tuple
+        * arguably, this is more in the spirit of a Linda/TS program, and less dependent on how different OS's provide support for launching Linda processes with command line arguments.
+  * Discussion: modeling one model of concurrency with another
+    * shared memory (critical sections, etc.)
+    * Golang: channels (message passing)
+    * Ruby/Rinda: Linda and Tuple Space
+  * We don't always get to choose our language/library/stack
+  * Shear Sort (time permitting)
