• A memory and performance comparison between Seam+JSF and Wicket. Wicket wins both. Also check the comments for useful feedback. Possible reasons for the differences in performance are: JSF performs much more expression evaluation and the JSF lifecycle is much more complex.

• Talking about standards, the OASIS committee has updated a bunch of webservices specifications/standards.
  


• A nice post on how to write a Javascript client that sites can use to access your REST API. Biggest challenges that had to be solved were:

  2. The lack of wide browser support for HTML 5-style message passing between windows.
