If you ever want to give students an example of the dangers of exponential growth then this story of a hacker who's "worm" inadvertently shut down the most popular site on the Internet (at the time) and did so because it grew exponentially. Listen to his story (starting at 1:19:17 ) on how he shut down MySpace (this was clearly a while ago) and how it eventually got him banned from using computers. @SamyKamkar is a hacker and he is being interviewed by venture capitalist and self experimenter @tferriss. It's a great (and long) podcast but the story in question starts at 1:19:17. Have a listen.

Some new activities pointed out on the @Desmos Friday Five. A few from the last few weeks that I liked were Put the Point on the Line which gives a nice intuitive way to introduce the idea of slope a neat little scatter plot activity called Commuting Times that includes a Which One Doesn't Belong at the end. I also like Parabola Slalom which makes good use of the new sketch feature. And on today's Friday Five there are a bunch of previously shown activities all dealing with parabolas, like Match my Parabola or Will it Hit the Hoop.
