[Pgubook-readers] Next PGU Book - Add real world useful example(s)?

[Roger]

After visiting the https://github.com/johnnyb/programming_under_the_hood which 
currently describes the goals for the next PGU book, I would suggest (if not 
already planned) adding one or a few real world useful examples.

For example, a Bash scripting example might include a script/code snippet for 
renaming multiple files at once, for teaching variable assignments and loops.

I might be going out on a limb here as I do not always use Assembly language 
for programming, more or less reading the book was for learning the inner 
workings of the computer as well as learning Assembly coding.  But it would be 
nice to see an explanation of how and where the Assembly language is still 
useful and actively utilized within today's world.

A possibly good example for starters would be to explain a popular CPU 
optimization register.  (ie. Intel's mmx, sse, ...)  And/or describing a 
low-level (GCC) compiler source code snippet?  (The later could likely be 
easily rolled into using the Intel MMX/SSE registers, etc.)  Albeit, this is 
pretty simple when one sits down and thinks about it, but this might be 
noteworthy?
