One of its more novel features is eschewing DOM manipulation in the code by binding data to the view; either updates when the other changes. http://angularjs.org/ Web Components, reusable chunks of web page, and the `shadow DOM'. http://www.w3.org/TR/2013/WD-components-intro-20130606/#introduction https://developers.google.com/events/io/sessions/318907648 http://www.webcomponentsshift.com/ "Quadtrees are most often used to partition a two-dimensional space by recursively subdividing it into four quadrants or regions." http://en.wikipedia.org/wiki/Quadtree Interleaving the bits of an (x, y) coordinate gives a locality-preserving hash and is related to Z-order curves; "a function which maps multidimensional data to one dimension while preserving locality of the data points". Also ties in with quadtrees. http://en.wikipedia.org/wiki/Locality_preserving_hashing http://en.wikipedia.org/wiki/Z-order_curve (Some pretty diagrams.) _High Performance Browser Networking_ by Ilya Grigorik is a new O'Reilly book currently available online as HTML for free whilst it's being drafted. http://chimera.labs.oreilly.com/books/1230000000545/index.html Ilya again, explaining how you've about 14KiB of data in the first round-trip time and what to put it in for a web page. _Optimizing the Critical Rendering Path, nuts and bolts of delivering instant mobile websites_. https://docs.google.com/presentation/d/1IRHyU7_crIiCjl0Gvue0WY3eY_eYvFQvSfwQouW9368/present Detailed analysis of fetching a web page in a browser, with tips for improvements. http://www.webpagetest.org/ After Google's SPDY, which is making its way into HTTP 2.0, they've QUIC; Quick UDP Internet Connections. http://en.wikipedia.org/wiki/QUIC Two keen Go advocates present meant it got a fair bit of coverage!
