A continuing saga of problems with software system
is chronicled in the "Risks" section of ACM journal,
"Software Engineering Notes".
The Risks section has appeared in every issue for
more than ten years,
i.e. there has been no shortage of material to keep it alive
for all that time!
Be the end of this course, you should understand that
hacking is far from clever:
there are much more effective strategies for making
programs run faster!
