The Optimistic and Pessimistic locks are basic patterns, which can in turn be composed with other ones. The Coarse Grained Lock pattern is a combination of the Aggregate pattern and of a lock-related one.

Below are two screenshots from the mobile view of Full Frontal, my JavaScript conference:Making the iPhone hide the url bar is fairly...

A constant drag when developing web sites have been when the end user wants to upload files to it. Luckily, though, those problems are to come to an end due to the File API. What is it? The File API is there to describe how interactions with files are handled, for reading information about them and their data as well, to be able to upload it.
