Mathoverflow and Mathematics Stackexchange are great places to ask and answer mathematical questions.

LyX is a really good editor for first-time-latex-ers. You can see all the formulae as you type, and you can type them in latex code or by pressing buttons (useful for matrices and commutative diagrams!) And Detexify will give you the latex code for a symbol when you draw it with a mouse.

Tools: PDFMerge, SplitPDF, DoPDF, which "prints" files to PDF, and iPiccy for making photo collages.

Comics: PhD Comics, Spiked Math, 101 uses for Lang's Algebra, Research in Progress tumblr

Places to eat: Nexus, Bytes, Arbuckle, Coupa, Ike's, dining halls.

Coma University of Mathematics is an awesome Japanese pop-math show (unfortunately I can't find anything on it in English).

I bought two permutation toys from this shop (the physical shop, I've never tried online ordering). They are for decoration only, I don't think about solving them. Come to my office (381F) if you want to play with them, and have a chance of getting your name on here! Kevin G of SUMaC '11 has solved the skewb with hints from the Internet and Peter McNamara has solved both the skewb and the mosaic cube. Thanks to Kayla, SUMaC '11 and Bana for giving me coloured tape / nail varnish to replace the stickers that have fallen off my skewb.
