If you write a blog post about something like this at least finish the damn thing rather than to leave a bunch of obviously wrong snippets laying around to confuse whoever lands on that page.
There are plenty of good pages on introductory assembler on the web, this isn't one of those and I'm really surprised to see it this high on the homepage. Maybe it shows how much the HN crowd would like to get a little bit of insight of what actually powers their computers, the error is mine in assuming that such knowledge would be commonplace here.
