hah - I had a high school teacher (~20 years ago - she taught the computer class) and she constantly called the entire box a 'cpu' too - a few of us gave her grief for it but it was all in good fun.

BTW I think your blog looks clean, good luck with it. Getting to the front page on HN isn't that hard, it's only a matter of time if you keep submitting.

Oh yeah - and definitely make separate pages for each blog post like rangerranvir mentioned - absolutely essential.
