This is echoing a feeling I've had now for the past year or so—the phrase
“premature optimization is the root of all evil” has been so drilled into
programmers that it seems like no thought at all is being employed.
Technically speaking, writing code is “premature optimization.” Why bother
even writing code when we can call upon the mighty powers of the lazy web [3]
to see if it's been written already. Or something close. Heck, it doesn't
even have to be close, as long as it's code that can be adapted (just try to
ignore the time factor when it takes longer to adapt code than it would have
taken to write code from scratch, which may make a better impedance match to
the rest of your code).
So remember, thinking about your code is a form of premature optimization.
