SRE,
What I like most about a lot of the things that you put on your website is that it is mostly real world stuff that you can use that is not dependent on computers or a degree in mathmatics to apply. More often than not you just need a reasonable approximate solution that will work and not 20 hours of analysis to get there. Thanks for everything you put on the site and to everyone that contributes to it. As a younger engineer I am always eager to absorb the "older" methods, which are becoming more and more difficult to get your hands on.
