Hello world, again

I've disappeared for more than 4 years in blog space. During this time period, I left CLR team and worked for Microsoft's High Performance Computing (HPC) team for 3 years to build Windows based compute cluster infrastructure. One thing I'm particularly proud of is that in Super Computing 2008, a system powered by our product (Windows HPC Server 2008) hits #10 in the world's Top 500 Super Computer list. Recently I joined Microsoft's Application Server Group (ASG) to work on Windows based application server products. Specially, my team focuses on Windows Workflow Foundation (WF) and Windows Communication Foundation (WCF). I decide to start the blogging hobby again to share more insights on WCF/WF. Please stay tuned. :)
