You’ve found a bug in Cairngorm.

REASON FIVE: You’ve found a bug in Cairngorm.

If you find a bug in Cairngorm, there’s a really good chance it’s too
early for you to be using it in mission critical projects. I state
this with confidence, because many years ago I was a C developer who
kept finding bugs in Kernighan and Ritchie’s C compiler. Every day,
I’d find something wrong with the compiler – in fact, come to think of
it, I think I was responsible for finding some real clangers in the
Pascal compiler on SunOS as well, back in the day.

Well, I say bugs … more often than not (in fact, come to think of it I
don’t think I’ve ever successfully filed a bug against a compiler)
they turned out not to be bugs. But they almost were … had it not been
for the mistake that *I* had made! In fairness, I think Ali found a
bug in the Java compiler once, but then he also refused to allow
iteration::two to accept a tax refund from Inland Revenue, because he
found a flaw in their calculations when we were subjected to a routine
VAT inspection. It takes a special kind of pedant to find bugs in
compilers, and flaws in Inland Revenue VAT calculations. Hope that
this isn’t you.

Seriously; I don’t want to suggest there haven’t been bugs in
Cairngorm, and when we’ve been through early betas, like any other
software products, we’ve allowed the occasional bug to slip
through. However, the Cairngorm releases that we make publically
available, compiled as SWCs … we use those a lot. We eat our own
dogfood. There are a lot of folks in the community using them, and if
you can’t get the basic login sample that we ship to work then I’ll
hazard a guess that it’s a flaw in your system setup, not a bug in
Cairngorm.

If you’re getting frustrated that you’ve found a bug in Cairngorm, and
you don’t know what the error message means – there’s a pretty good
chance that a little bit more time spent up at REASON ONE, writing
some more sample applications and experiencing compiler errors while
you take your baby-steps, will help you steam past the configuration
problems you’re probably experiencing with your particular Cairngorm
sample application.
