So close, yet so far

I noticed a GUID that got generated by our app for some stuff.

While I was in the Air Force, one of our mission mainframes crashdumps all started with 0XDEAD

Well yes, hex is written in upper case. But this is a GUID, which is frequently stored as a text string, and is case-sensitive. Google for upper/lower case GUID and you'll find all sorts of pain; some systems generate GUIDs in upper case, some in lower. For those database systems that have a field type of GUID, most will return their text form as upper case, but not necessarily all do. If in any doubt where your GUIDs are coming from (e.g. a URL querystring) always be aware when doing comparisons! :-)
