The Storage Engine Team (aka Paul Randal) has started the series on DBCC. First up is CHECKDB and consistency. Fantastic post interesting to see that something new in 2000 was re-written for 2005. Second is PAGE, yep this is a Microsoft person blogging about an undocumented (but heavily used as Paul explains) command. This blog is essential reading for anyone wanting to now the ins and outs of SQL Server.
Data Dude CTP is supposed to be available today, I was hoping to provide a public link but unfortunately it isn't available and only available to MSDN scubscribers (according to ScottGu)
SQL Everywhere is also available as a CTP. It is the new mobile edition of SQL Server that is loaded in memory, so think of it like dbf files or other non-service based databases. (Thanks to Dan for pointing this out) Also check out Steve Lasker's post on SQL Everywhere
