5. Oracle Magazine January/Februray 2011 - Simplicity by Design


6. 10 Things Java Should Steal from Ruby:

This was a session that was done by Bruce Tate in August of 2006. Discussion on how things look today is given below:

• Continuations which are basically syntactic method of implementing certain types of optimization, are not deemed to be a part of Java.
• Meta-programming is not available to Java because of the very nature of how statically typed the language is.
• Conventions over XML, ease of development in Java EE 5, which had to do with convention of a configuration as well as annotations rather than XML if you wanted to change that default behavior.

There were few other points which can be heard in the podcast.
