It is a sad and known fact that having lots of ACLs in your SharePoint database has a negative effect on the performance of your site. What I did not know yet was that changes to the ACL will impact your incremental crawls.

This week I gave a presentation at Winvision and recorded it in Microsoft Office Live Meeting 2007. The resulting recording is a webpage with multiple streams: desktop video, presenter video and audio.

The problem is that the codec used does not work on x64 systems or Windows 7 (Server). Watching the separate streams is not really an option because there is no audio included in the video streams.

I have a clean install on the latest and greatest: Windows Server 2008, SQL Server 2008 and MOSS 2007 SP1 with all updates. This is the layout of my farm:

http://<server>:80   - Portal
http://<server>:8000 - Central Admin
http://<server>:8001 - SSP
http://mysite        - MySites

Everything works fine, except the search crawl gave Access Denied errors on http://mysite and sps3://mysite.

While working on a project with some existing code I noticed the developer did write large portions of code to get from an URL to a SPList. He probably didn’t know some of the hidden gems in SharePoint.

Sometimes you have to split your code into different assemblies. For example, when I created a custom Admin Page which inherits from WebAdminPageBase (Microsoft.SharePoint.ApplicationPages).

The problem with Microsoft.SharePoint.ApplicationPages is that it is not deployed to the GAC.
