Geeky guild names for World of Warcraft

I was trying to think of some really geeky names that would do well as guild names. Have any good ideas? I was thinking:

• Recursive Descent
• UTF-25
• RAID 5
• Garbage Collection
• Order N
• Group Theory
• Abstract Class
• Instance Method

Some names that are fun just for having the tag under your name, like a vendor or quest mob:

• Traveling Salesman
• Venn Door
• filename
• options
• Virtual Member

I think my favorites are Recursive Descent and Instance Method. Hard to choose...
