    There are those, but there are others, most of which are so obvious[1]
    we're not mentioning them, assuming you're familiar with them too. I
    usually eschew debuggers as well, but I'm beginning to suspect that you've
    spent so much of your programming life immersed in the kernel that you
    haven't used a debugger enough to know what sorts of things it's actually
    good for. Not all the world's a nail, but there are times when the bigger
    hammer approach is the right one.

    One of these days you should give revision control a try too. Not to
    mention bug tracking. :P

    [1] eg I've found many a compiler bug in 5 minutes of single stepping that
    days of eyeballing source and adding printfs failed to discover.
