I am pumped up about TechEd. Bill Gates's last technical keynote. He has to have a bomb to drop... The launch of Windows\VS\SQL Server 2008. All of the speakers are reaching deep into their bag of tricks and bringing new hardcore sessions. The universal party. The blogger's lounge. Twitter, FriendFeed, MSDN, and Technet are all buzzing with posts.
I found out a couple of days ago that a speaker would not be able to make it due to a family emergency. I offered to present his session on DMV's so I will be presenting these sessions:
Using Dynamic Management Views to Improve Your Development
Dynamic Management Views were added to SQL Server 2005 and have been enhanced in SQL Server 2008. While they provide great functionality and usefulness, it appears they are not widely understood or implemented as yet. This session provides an overview of the Dynamic Management Objects available (both Views and Functions) and describes those considered the most useful. It shows how they can be utilized in monitoring, troubleshooting, and ongoing management of SQL Server systems and in gaining an understanding of SQL Server’s operation. The session also illustrates how they can be used to improve the database development experience and how they can be used in custom reports within SQL Server Management Studio.

Windows Management Instrumentation (WMI) for the Command Line DBA
This is a demo filled session on how a command line DBA can unleash the power of WMI. WMI allows the DBA access to information that was previously hard to get or unavailable like the application event logs, OS perfmon counters, and OS events. This session covers WQL queries from SSIS, accessing OS performance counters from SQL, automated reactions to WMI events, WMI from Windows PowerShell and much more.

Troubleshooting Query Plans Gone Wrong
Have you ever flushed the procedure cache to resolve a performance problem? Have you ever had to use a join or index hint when you should not have to? Have you ever updated statistics to fix a performance problem and wondered why it worked? In this session, we get deep into how the query optimizer decides how to execute a SQL statement. We look at common problems that cause the optimizer to choose the wrong access paths like underestimation. We go over a detailed demo on parameter sniffing, problems with local variables and statistics. We also look at solutions to these problems in several areas including good design at the application, schema, and query levels, proactive maintenance and reactive fixes. This session applies to Microsoft SQL Server 2000 through 2008 but we pay special attention to new features in SQL Server 2008 like plan freezing, new hints, filter indexes, and statistics among others.

There are a couple new features that I would like to quickly point out. These are basically just tools that I use daily so I integrated them into the site. I hope you find them useful.
- I have everything running faster. Not a new feature per say but it definitely helps usability.
- I have extended the blog aggregator to include a lot more feeds. Let me know if you would like your feed to be added!
- I have added a digg SQL feed. I am using digg more often and find it useful so start digging(preferably starting with this post) so I do not have to resort to web 1.0 google searches.
- The SQL Server 2008 facebook group is linked. Join up and add me as a "web pal" Note: I am happily married and discourage webbernet stalking so please maintain so self control.
- I have also added an event page on where you can catch me speaking or download session slides and code from previous presentations.
- And if you have not had a chance to check out the MSDN and TechNet feeds, you are missing out.

Kalen Delaney's first DVD on SQL Server internals is available for viewing online. More details here.
Connor Cunningham, formerly on the SQL query optimizer team, is now blogging at SQL Skills and is whipping out posts on optimizer related topics at a frantic pace. Check out the latest here or all of them here.
Dan Jones rebuffs the idea that SQL Server 2008 is a "dot release".
CTP6 may or may not be coming soon. Chris says that CTP5 will be given away at the HHH launch. This is in contrast to the "feature complete" CTP that was mentioned in the roadmap but who know...
Mario B has raised some eyebrows with his post on scheduler troubleshooting and SOS_SCHEDULER_YIELD waits and the possibility that is is not CPU pressure always. Linchi posted about it here and then SQLServerPedia posts shortly afterwards. Anyway, check out Mario's tools.
