Thanks to incurable traffic of Los Angeles, I was stuck and will be stuck in the traffic for almost a whole week.  The pre-conference this year has a free workshop, Windows 7 Boot Camp, <em>hosted<\/em> by Mark Russinovich.  Yeah, he&#8217;s the host and he only talked about less than half an hour \ud83d\ude41<\/p>\n<p>In the morning they talked about Windows 7 core kernel changes and memory manager enhancements, both were quite informational and interesting.  I&#8217;m wondering if these two guys will be co-authoring Windows Internals 6th ed.  In short (well, <i>really<\/i> short, the enhancement of Windows 7 is mostly reducing lock contention.  Before they actually implemented Windows 7, they measured and identified that many performance bottlenecks were caused by lock contentions.  Therefore, Microsoft engineers replaced many coarse-grained lock with fine-grained lock hierarchy so that lock contentions could be reduced.  The outcome are very obvious: higher benchmarking for high-end systems, and more snappy response for client machines.<\/p>\n<p>The contents in the afternoon were quite a melange (and honestly, not a tasteful one IMO).  They talked about the <i>new features<\/i> of Windows 7 shell, location and sensor framework, and DirectX.  Well, the only <i>new<\/i> thing IMO is <i>you can use .Net to do those now<\/i>.  Thank you, I&#8217;ve already learned these features in PDC 08 with my faithful C++ and I don&#8217;t think P\/Invoke is that big a deal.  At least, the pricing is fair.  It&#8217;s free since you could find most of the contents last year.<\/p>\n<p>PS. It is not free if you did not get to LACC via public transit.  Parking fee is USD$12.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Some thoughts w.r.t.
