Competition for mindshare

Mindshare is a term I rarely hear outside of business or technology magazines, but is very appropriate here. Java has long been king in the unit testing space, and though hoary, JUnit is still one of the best unit testing libraries around.

But Ruby is giving Java serious competition. I am late to the party, but just ran across metric_fu in this post. I wish I had metric_fu for Java!

In the 90s the evolving Java ecosystem was the top reason I moved from C/C++ to Java. JDK7 looks to keep Java the language on life support so it will not immediate wither away (although who came up with the name public defender methods [PDF]?). But the library momentum is not in Java's favor at the moment.

Faster, JRuby! Faster!
