I'm one of the big fan of sample applications releasing from Microsoft because I think that they are one of the best way to learn how to build some types of complex applications.
Today Microsoft has released a great Business Intelligence Portal Sample Application for Microsoft Office, an integrated, web-based OLAP solution that enables employees in an organization to create and share OLAP/Relational/XML based views, using SharePoint Portal Server 2003, SQL Server Reporting Services, and Office Web components.
This is really interesting and complete, recommended if you're interested on these types of applications.
Microsoft, I love this "sample releasing" line... 
Secunia has published a new spoofing vulnerability that affects Internet Explorer (also IE6 with SP2 is affected). 
The vulnerability is caused due to an error in the DHTML Edit ActiveX control when handling the "execScript()" function in certain situations. This can be exploited to execute arbitrary script code in a user's browser session in context of an arbitrary site.
A test, which can be used to check if your browser is affected by this issue, is available at this address:

Solutions? For the moment, only the "do it yourself" actions: disable ActiveX support.
