Disqus, one of the largest Django applications in the world, will explain how they deal with scaling complexities in a small startup.

There are many benefits to keeping a lightweight stack. At Disqus, keeping the stack thin helps us scale Django to reach over 125 million unique visitors a month with just a small team of engineers. Avoiding complicated software packages until needed reduces unnecessary overhead, and has let us stay nimble, and use new capabilities in Django (i.e., database routing) and other software as they arise. The talk will cover key parts of the architecture and development process at Disqus, including databases (relational and non), queues, automated testing, and continuous deployment.

In this graphic, when a train departs from its originating station, its path is traced on this webpage as a growing coloured string that is "plucked" by intersecting trains. Just as with a real stringed instrument (a cello in this case), longer train lines make lower notes when "plucked" than short ones. Time accelerates in this graphic, so you can watch a 24-hour train cycle. An interesting addition to this map is the artist's inclusion of discontinued subway lines: these so-called "ghost trains" slip by in the middle of the night.

According to his blog, Brooklyn resident Alexander Chen built this web page by combining MTA's public Application Programming Interface with Javascript, vector graphics (SVG), HTML5 and a dash of Flash. Many people find the sounds soothing or mesmerising, and some have likened the resulting sounds produced by this graphic to the music of John Cage.

The use of embed has gone on too long. Wishing for it to become part of the official specs is like wishing your partner would start putting the cap on the toothpaste. It’s not going to happen.

Video for Everybody is simply a chunk of HTML code that embeds a video into a website using the HTML5 <video> element, falling back to Flash automatically, without the use of JavaScript or browser-sniffing. It therefore works in RSS readers (no JavaScript), on the iPhone / iPad (don’t support Flash) and on many, many browsers and platforms.

This scientific visualization creates a three-dimensional virtual tour of several dark pillars of cool gas in the Carina Nebula. The stars and nebula layers from Hubble's two-dimensional image have been separated using both scientific knowledge and artistic license to create the depth in the movie. Of note, the relative distances between stars and the nebula have been greatly compressed. The result is an intriguing journey through a virtual cosmic landscape.

This version of the movie is presented in anaglyph stereo 3D and is viewable with glasses that have a red lens over the left eye and a cyan (a.k.a. blue-green) lens over the right eye. Such glasses are often made of cardboard and have been distributed in numerous 3-D promotions. An internet search for "red cyan anaglyph glasses" will provide many options for obtaining such glasses.
