Some helpful tricks with LINKMEMBER. Linkmember is used when the cube has multiple hierarchies that could be linked together. Eg. Order Date & Ship Date could be linked together, even though no relationship exists at the fact level. Or in my case Security Code and Security Underlier Code.
The key issue I had was that the HideUnrelatedDimension property was set to false in the cube. This means that you need to explicitly specify the "all" member in the linkmember function, and exclude the all member from the scope of the calculation statement.
Details here.

Interesting MDX Feature
Apparently there's a keyword test in MDX that returns an empty value, even if the cube doesn't contain a measure called test...

Humor in code
So I've been getting this error fairly regularly and thought that Mario's arch enemy had done something to my PC. Lately it has been shutting off without warning.
The Source was "Bowser"
The browser driver has received too many illegal datagrams from the remote computer ---- to name WORKGROUP on transport NetBT_Tcpip_{-----}. The data is the datagram. No more events will be generated until the reset frequency has expired.

Apparently this means my computer is beyond repair, or at least the network card is sending out line noise.
Another one that happens every minute since I installed Windows 8:
A corrected hardware error has occurred.
Reported by component: Processor Core
Error Source: Corrected Machine Check
Error Type: No Error
Processor ID: 1
The details view of this entry contains further information.
If it's corrected, how come it keeps showing up every minute?
If it's not an error, why is it called a corrected hardware error?
I always thought the event viewer should have ads for software that fixes event viewer errors or offers up places to buy hardware. That could be a great idea for extra MS revenue...
Reading Larry's blog, I finally figured out how I fixed that insurance office network 17 years ago.

Flipping the network cards from Auto Detect to Full Duplex solved the issue, since 1 card was blowing up the entire network.
