Today, there are 5 billion devices connected to the Web. By 2020, there will be over 50 billion – always on and always exchanging data. That’s the Living Web : dynamic, interactive, collaborative and marked by explosive growth. It's an environment existing Web infrastructure was never designed to support. The Kaazing Platform was designed exclusively for this mission: to support and accelerate the transition from legacy Web to Living Web. Existing Web infrastructure relies on workarounds such as Comet, AJAX and long polling to make the static, legacy Web appear to support real-time interaction.
The next iteration of HTML has been met with excitement by some, loathing by others and confusion/fear by everyone else. Love it or hate it, HTML 5 will soon define how you build websites. This is the first article in a four part series that will introduce HTML5 and its basic features as well as explain the key differences from HTML4.01 and XHTML 1.0 so you can start preparing yourself and your sites for the transition.
In March 1936, an unusual confluence of forces occurred in Santa Clara County. A long cold winter delayed the blossoming of the millions of cherry, apricot, peach, and prune plum trees covering hundreds of square miles of the Valley floor. Then, unlike many years, the rains that followed were light and too early to knock the blossoms from their branches. Instead, by the billions, they all burst open at once. Seemingly overnight, the ocean of green that was the Valley turned into a low, soft, dizzyingly perfumed cloud of pink and white.
Since most interactions only involve a single dimension, and then only small adjustments are made to the filter values, incremental filtering and reducing is significantly faster than starting from scratch. Crossfilter uses sorted indexes (and a few bit-twiddling hacks) to make this possible, dramatically increasing the performance of live histograms and top-K lists.
