And, again, just a guess, but I'm guessing the huge percentage of
programmers these days are writing .NET code on vanilla Windows
machines
(not that I like it, but it does seem to be a fact of life). A lot
of
people also seem to be writing stored SQL procedures to run on MS
SQL.
Bad guess. .NET is way down the list of popularity (much to
Microsoft's chagrin). COBOL is still number 1; C/C++ still way
surpass .NET. And MSSQL is well behind MySQL in the number of
installations (I think Oracle is still #1 with DB2 #2).
I expect that there are NOT a lot of people writing production code
to
run on Debian, expect for use on internal servers. When it comes to
writing Unix code for Government or Corporate environments, or for
products that run on Unix, the target is usually either Solaris, AIX
(maybe), and Red Hat.
I would say not necessarily writing for Debian, but writing for Linux
in general is pretty popular, and getting more so.
