HTML5 video markup, compatibility and playback
The emerging HTML5 specification lifts video playback out of the generic object element and into specialized video handlers. Explicit markup for audio and video places elevates moving pictures to a similar native rendering capacity as img markup we are used to but with more fine-grained details about underlying formats and compression available before loading. In this post I will dive into implementation details of HTML5 video based on currently available consuming agents and outline some of the nuances of preparing media for playback.

In the world of cloud computing every action has a cost. Every HTTP request fires off a chain of actions, each uniquely measured on a variety of billable meters. Gone are the days of idle or unused resources on our local servers. Cloud computing charges by the sip (when sips are available) aligning business goals of resource efficiency and its cost. The cloud computing world shares many similarities with the plug-in and go world of electricity, including the need to run green for the sake of resources and cost savings. What can the world of green energy teach us about the future of cloud computing? How can we measure computing resources in the cloud for efficiency, replacement costs, and cost savings?
