When trying to compare a Date field with a DateTime field in an APEX SOQL query I got the following error:
Invalid bind expression type of Datetime for column of type Date
The solution was to use date.newinstance(year, month, day) rather than the raw DateTime value in the comparison. Year, month, and day are found using the methods of the same name on the DateTime object.
Kirk Jackson will be giving a presentation on Wednesday the 19th of August.
Title:
Best practice - Caching
Abstract:
At some point in your application development, you'll need to start caching data or the output of your program. Scalability, performance, bytes transferred, speed, reliability and robustness can all be improved through judicious use of caching. The first half of the talk will cover the types of caching and motivations for using them -- through all layers of your app: SQL, C#, ASP.NET and through to the browser cache. The second half of the talk will briefly cover memcached, which is used by all the cool kids (YouTube, Facebook, Trade Me), and then introduce the Microsoft project code named Velocity (currently CTP), which brings all that coolness and more to the .NET platform.

Error 27506.Error executing SQL script attach. Line 5. Directory lookup for the file "D:\websites\instance name\Databases\\Sitecore.Core.MDF" failed with the operating system error 3(error not found). (5133)
The Sitecore installation wizard kept failing at the Executing SQL Install Script step when installing to a remote database. Running the install from the database server avoided the issue.
I've also seen the error appear as:
Error -2147217900: failed to execute SQL string, error detail: Directory lookup for the file "D:\websites\instance name\Databases\MDF\...\Sitecore.Core.ldf') FOR ATTACH"
