Hudson is great for managing scheduled builds, but after a while the artifacts start to take up a considerable amount of space.

Deleting them one by one is possible, but Hudson will do this for you:

Note that this works retroactively. If you have 300 old builds and set the job to keep just 20, the next build will delete 281 builds.

Quick Tip: Is your site suddenly requesting a user name and password?

Most likely this is triggered by insufficient file system permissions. The error logs at
%SYSTEMROOT%\System32\LogFiles\W3SVC###\*.log will narrow down your search and give the substatus and Win32
error codes for each HTTP 401.

David Wang has a great write up about this on his blog. Check it out for more details.

Quick tip:   The table name and index name are required to drop an index, otherwise SQL Server will return an error.

e.g.

DROP INDEX [dbo].[IX_MyIndex]

fails with …

Msg 3701, Level 11, State 6, Line XX
Cannot drop the index 'dbo.IX_MyIndex', 
because it does not exist or you do not have permission.

However,

DROP INDEX [dbo].[MyTable].[IX_MyIndex]

will work fine if it exists and you have sufficient permissions. (Use Select user_name() to determine your user context, which will help to verify the permissions being used.)

'n++ECHO' is not recognized as an internal or external command, operable program or batch file.

Open the file in Notepad++, select ‘Format -> Encode in ANSI’ and save.

Hope that helps someone.  Happy Programming!
