The language will matter at least as much as your choice of CPU, switch
brand, networking topology and so on, to the total performance of your
computational "solution" - so yes, I hope you are the only one failing
to see its relevance  :)

I, like most others probably, don't have time to keep up to date on all
languages in practical use today.  I most likely don't even *know* about
all languages in practical use today.

And I just love to see examples like the word-count program in Java (I
was surprised at that one!), C++ (I knew that one), and Fortran (I was
happy to see that Fortran has evolved somewhat since my F77+extensions
days).

I was even corrected on a C optimization issue (thanks Greg!). I learnt
something useful today  :)

The word-count example is in essence not so different from your average
factorization problem - languages abilities, compiler abilities,
optimization possibilities, raw code speed... these are parameters that
are all relevant to many 'wulfers.

The list is wery wide in it's subjects; everything from AC wiring to SMP
scalability, over Scyld installation problems to switch performance
measurements is regularly being discussed.  I for one do not feel that a
language discussion is the least bit off topic.  After all, we do code
in languages   :)

(well, except for the F...... people   /me runs   ;)
