A little while ago Jason Grigsby wrote a great post outlining his “wish list” for how the <img> tag should change to simplify mobile design (and specifically Responsive Images). The post created a lot of good conversation, and hopefully some standards activity too. At the end of the day, browser makers and developers share a common goal of making the web better, so this type of feedback helps.
In the last few months I’ve been giving several presentations about Mobile Web Performance in various venues such as Walmart, Time and others. I also had the honor of giving this presentation as a Google Tech Talk, and the google team recorded a video of this presentation.
The video is now up you can watch it below, and you can also read the blog post in the Google Code blog here:

For better audio you can see our webinar of the same presentation below:
Recently we came across a problem so bizarre I was amazed I never saw it before: IE executes dynamically created scripts before they’re added to the DOM!

Last saturday I had the honor of writing a guest post in the great Performance Calendar, a part of Planet Performance (@perfplanet), and run by Stoyan Stefanov and Sergey Chernyshev.
The post deals with the common mistake of thinking reducing requests is all that matters, and shows various examples where it will actually slow down your site.
