I found the article Slate published today more interesting <a href="http://www.slate.com/articles/technology/history/2013/09/danny_lewin_the_first_victim_on_9_11_and_an_architect_of_the_internet.html" rel="nofollow">http://www.slate.com/articles/technology/history/2013/09/dan...</a> (was written by the author of Lewin's bio)
I respect that we should remember the victims and particularly those related to the tech industry on HN, but this article is difficult to read based on how often the author has to over-emphasize Lewin's achievements.
