On a related note, it took me years of playing with *nix to notice that the notations '&' and '|' were chosen to mimic series and parallel operations. These days we tend to think of '&' as a backgrounding operation, and it's almost always the final token in a command:<p><pre><code> $ some_background_command &
</code></pre>
I suspect it was originally intended to run commands in parallel:<p><pre><code> $ command1 & command2</code></pre>
This is brilliance - epiphany for sure. I will try this.<p>All the folks out there working with arduinos and the like and having to diagram/proto the pins and their control, particular I2C might find this useful...which is what im going to try use it for.
