It's being an interesting trend where heterogeneous services were exposed and now can be consumed by a variety of consumers, say, publishers with PDFs, online content with Netflix. The underlying standards are called OData which details can be found at http://www.odata.org Today, many sites expose their data in OData-compatible format, see here. If you're developing a new application, consider exposing your data in that format. Also, watch out the extended integration throughout the Microsoft products for examples of using it at MIX'11.

This was reposted a miriad of times, but I seem to can't find it when needed, so here it is, the famous slow query sql:

SELECT TOP 20 SUBSTRING(qt.text, (qs.statement_start_offset/2)+1, 
        ((CASE qs.statement_end_offset
          WHEN -1 THEN DATALENGTH(qt.text)
         ELSE qs.statement_end_offset
         END - qs.statement_start_offset)/2)+1), 
qs.execution_count, 
qs.total_logical_reads, qs.last_logical_reads,
qs.min_logical_reads, qs.max_logical_reads,
qs.total_elapsed_time, qs.last_elapsed_time,
qs.min_elapsed_time, qs.max_elapsed_time,
qs.last_execution_time,
qp.query_plan
FROM sys.dm_exec_query_stats qs
CROSS APPLY sys.dm_exec_sql_text(qs.sql_handle) qt
CROSS APPLY sys.dm_exec_query_plan(qs.plan_handle) qp
WHERE qt.encrypted=0
ORDER BY qs.total_logical_reads DESC

Periodically, I need to parse a string, which represents an xml file into formatted file with intendation. Here is a simple .Net code which does this and can be compiled into a console application:

Here is the complete info:http://realfiction.net/go/153. The gist of it is that you create a symbolik link under %WINDIR%\System32 and %WINDIR%\SysWOW64 to point to either 32 or 64-bit oracle client depending on the bitness of a client app.

I'm opening a new series of posts related to performance optimization of software systems, which is my primary area lately. First, and most useful suggestion when it comes to setting up the environment, pay attention to the exact spec of the testing system, namely, CPU, disk, memory, software installed and running etc.
