This week I have taken up studying missile guidance and these were some websites from which I would be taking my notes from.
Thought this might pique someone's interest from the HN brethren as well.
Please don't submit so many links at once that the new page is dominated by your submissions.
Maybe five out of thirty isn't dominating, but it stood out to me. I would much rather have seen a neat blog post that shared your findings and had the references.
But my comment has been downvoted, I guess I'm in a minority, and it shows yet again how much I'm out-of-step with the HN "community".

Is there some point you're trying to make? Why flood the front page, a scarce resource, with five things all on the same topic?
