Do you know where your variables are?

To me, apart from the various points people have made about using warnings and strictures, structured code, using subroutines and so forth, the most important rule is:

Use meaningful names!

This applies to variables, subroutines, loops, filehandles, everything.

Always take a little extra time, 10 seconds or so, to name your variables well.

Good names can often make comments redundant and unnecessary.

I hope I never ever have to maintain a program again that's full of variables named @tmp, $i, $n, $ldr, %hash or subroutines named process or run and all the other meaningless crap people foist off as names.

    [ambrus]: Corion: no, backwards. It's possible in the general case, but not in the specific case of bad data we have. Which is why it's harder to explain.
    [marto]: that reminds me, to donate...
    [ambrus]: If it was possible in this specific case, then the burden to argue for that would be his.
    [Corion]: ambrus: Ah, but he's the boss, so the burden to show that it's impossible still lies on you :-)
    [Corion]: ambrus: I would work with him through an example
