How to Level Up

I regularly hear from and read about technologists in a career rut. Unless one is both lucky and adept at predicting the future, experiencing some temporary stall can happen to professionals at any career stage. It may be the feeling of being stuck in an unchallenging role, feeling burdened by an undesirable skill set, or trapped in a company that seems difficult to escape.

Attempt to map WCF to Java terms

By writing this post I’m taking a huge risk of being rejected by both .NET and Java communities. This is an attempt to explain what WCF, which stands for Windows Communication Foundation, is in Java terms. WCF-to-Java mapping is not really trivial.
