I usually don’t see Perl in Dr. Dobbs, but the January 2005 issue is all about open source and programming languages, and it has one of the best tech articles I’ve seen in a while.
This issue includes Sam Tregar’s “Perl, VMWare, & Virtual Solutions”. He’s the author of Writing Perl Modules for CPAN (one of the best Perl books out there), and works on Krang, a mod_perl based content management system.
None of that really matters for this article though, because that’s not really what he’s talking about (open source or Perl or Krang). He talking about money.
He used VMWare to test his product on a bunch of different architectures and operating systems without buying all those architectures. That’s right: he gets down to the money. He’s done his math and figured out the real dollar cost each way. He’s not using VMWare just because he likes it: it saves him a tens of thousand of dollars, even though it costs him a few thousand dollars. It’s great to see the article hit not only the tech angle, but the practical business angle too.
And it’s all in Dr. Dobbs. Imagine that.
