My celebration is subdued this year, for various reasons, but I hope all of you have a good day. I also hope that you have some pie today, whether you go out somewhere or bake your own. (And if you feel like baking your own, once again I’ll link to the King Arthur Flour pie crust video.)
Also, the good folks at O’Reilly are offering 50% off on “science and math” ebooks today, just in case you see something you’re interested in.
