Carl and Richard talk to Shawn Wildermuth about his experiences building mobile applications - first! The conversation starts out with the challenges of making mobile web applications that work well. Web pages have gotten too large to load quickly or render effectively, HTTP Archive says in 2013 the average page size is 1.2MB! Shawn digs into how to architect a page so that it sends down the mobile version first, fast and light for a phone, but also usable on a regular browser, and then load additional resources if the browser is capable. Great discussions on dealing with retina displays and bandwidth restrictions as well. Time to evolve your web page design!
