The first highlight from yesterday came from XKCD with the comic Tornado. As usual with XKCD, make sure you read the image alt text as well. We also have some really interesting performance articles today. First, High Scalability talks about what PAPER did to handle the traffic for their Kim Kardashian shoot. The High Scalability article is sage to read, but the PAPER article definitely is NSFW. Elie Rotenberg gives us an overview of building a million user webchat.

As always, enjoy today’s items, and please participate in the discussions on these sites.
