I wrote the beginning of the previous entry twice. The old mozilla managed to crash just while editing that post (and googling for the URLs). Ok, if you can't even remember what you wrote then it's not worth it anyway. But being a programmer I do not like repeating myself, or repeating the refinements of text; I even notice that it bugs me when I actually write code fragments on paper and can't just insert the argument I forget and have to rewrite the whole line.
So forgo the blogger edit window and use the friendly local emacs, where your idle process types ^X^S anyway after a few seconds' timeout.
