I don't think I took a "sensible pill". :-)
I fairly routinely encounter uninformed programmers, or prima donna
programmers. Or simply 9-5 M-F uninterested unionized programmers who
can't lose their job even if they do nothing. Over thirty years this
covers several hundred projects, teams and clients (in-depth knowledge
of those situations even if I wasn't actually directly involved), so I
don't think my observations are completely anecdotal or without merit.
The LCD is the average guy - and these days it's still overwhelmingly
guys - who isn't all that experienced (after all, every one of us once
had just 2 or 5 or 10 years of experience), who may not be formally
trained or may be badly educated, who may not be that motivated, and who
quite often regards programming as a way to pay the bills and not as a
craft nor as a delight.
If we stick to Java, the LCD doesn't quite get the difference between
reference and equals() comparisons, and when informed still needs
coaching to write a good equals(). The LCD often has never heard of
O(n), and far from being able to choose a good sort has in fact never
heard of most of the common sorting algorithms. Same goes for search, I
run across coders all the time that have never heard of fundamental
search strategies. This average programmer doesn't read blogs or
articles, doesn't know white box or black box testing theory, knows
almost nothing about JVM tuning [1], and is very weak on concurrency. So
forth and so on.
This is what *I* see in industry, in government and large corporate IT
projects. But maybe other folks have experienced idylls of nothing but
top-notch developers, and have started to get complacent. Dunno.
I don't know why there's even an argument about this, either defensive
coding or dumbing stuff down. In the real non-academic world you've got
to do it.
