Today's talk and links ahoy

First, happy late birthday to dreamweaver15 and whenshewasmine, and happy early birthday to ladysilmarien!

We gave our talk today. It went pretty well, but it feels really good to get that out of the way. I put in tons of pop culture references in my slides, including the title of every slide I talked about. I was going through the proof that motivated our problem (which took several slides), and I heard Jared snickering when I got to "Proof: Reloaded". The first of the proof slides was Proof, and after that I just went crazy with the movie sequels. The last one? Proof Forever.

So I showed them examples of sum-free sets and sets that aren't sum-free. The sum-free set?

{42, 404, 1337, 8675309}

The non-sum-free set?

{4, 8, 15, 16, 23, 42}

I love being a geek.

Here, have some links.

Also thanks to Uncyclopedia, Afairyism, or the lack of belief in fairies. I may not be cranky or an atheist, but I'm digging the deeper message.

Secondhand Songs is awesome, especially their stats section. The stats aren't complete because stuff is always being entered, and I know it isn't complete because I know Leonard Cohen's "Hallelujah" has been covered more than they claim it has--I have the original and around twenty covers, and there are covers I don't have. :P My favorite part of the site has to be the Cover Chain. It's exactly what it sounds like: A covered a song by B, who covered a song by C, et cetera. Every artist in the chain is covered only once, so the Beatles don't show up 34234 times. It reminds me a little of Erdös numbers or the Bacon chain game, except you're not counting distance from a central figure. Pretty cool, je crois.
