Damn that was good! Perhaps we should start calling you Speedy Gonzalez :-) You sound like my ex-girlfriend's mother. She was totally sick on a bike. Used to get off the back of her wheels with legs like spaghetti and a head full of thunderous ear-splitting panic. Took me right back. Mate that used to wake me up in the mornings that's for sure.Cheers,Jules

This often seems to happen, though. I find design patterns to be
incredibly useful for attaching names to common code constructs (both
for describing how something was implemented or how it could/should be
implemented) but I find them unhelpful whenever they're wedged into a
context where the potential user of the pattern hasn't previously worked
on the problem and personally experienced the pain of coding themselves
into a corner. They get locked up in a terror that they aren't
following the pattern to the letter, and freak out when the pattern
isn't a 100% match for what they're trying to do. I once saw some code
that had a class factory that produced class factories, for no reason
other than they didn't dare put two factory methods on the same object,
because the pattern didn't say that was ok.
To bring it back to an area near and dear to my heart, its like
explaining lanesplitting techniques to a motorcyclist who lives in a
rural area with no traffic. Sure, there are lots of best practices and
potential gotchas and what-to-do-when, but they're only interesting from
a theoretical perspective if you're never in that situation. However,
they'll make a lot more sense -after- a cell-phone-babbling soccer mom
in a Maibatsu Monstrosity suddenly realizes she needs to exit soon and
cuts you off, forcing you to threshold brake, release, swerve a full
lanes-width in front of a bus to the next gap between lanes, and then
accelerate so hard you pull a small wheelie off a rain-slicked Bott's
Dot while still leaned over, three cylinders of bottled impatience
howling as you feed 120hp to the ground via a sticky rubber contact
patch the size of a deck of cards[1] (Ah, Lanesplitting Pattern #4, on-
and off-ramps are like tributaries in the traffic stream, they cause
turbulence...)

into source control a bit more frequently than my sane coworkers.
