Still no idea what it's from but I have discovered how it got to my desk. My son was walking in the lounge room when it stuck to his foot. Didn't think to look for what it was from.
Just, I think I'll stick this on Dad's desk.

It's probably a half-eaten gummy-bear egg, then.

Or possibly an NSA bugging device...I've heard they are looking for Australian subversives who can brew their own beer...

I've heard of Australians who can brew their own beer by subversiving their feet in a bowl of water.

Nah, he 17 in a couple of months and bigger than Maunder. Pizzas and chocolate bars are more likely.

Searching for the number of possible GUIDs (answering questions in the forum section) I struggled over this amusing SO Thread where they are seriously discussing how the non-unique nature of a GUID can be proofed.
Enjoy[^]
Edit -> Here is my answer to the said question (can you think of a creative one yourself?):
Quote: A Guid is 128 bit. Therefore you would have to generate 2^128 + 1 GUIDs to encounter a single GUID twice.
A thread on StackOverflow.com[^] says that you would need about 10790283070806014188970 years to encounter a single GUID twice, assuming your program does nothing else than creating GUIDs and runs at a processor speed of 1 GhZ, without any interruption by CPU power eaten by other programs or the operating system itself.
As you probably can think now, encountering the same GUID twice would be very bad luck and can safely considered as being unrealistic.
People becoming wiser in order to notice the stupid things they did back in the young days. This doesn't mean that they really stop doing those things. Wise people still do stupid things, only on purpose.

I have always argued (mostly unsuccessfully) that any system that aims to be reliable cannot depend on the uniqueness of GUIDs.
There is no problem that they solve that cannot also be solved in a way that is guaranteed to be reliable (although the solution may be more complex)
Sure, it may not happen, but it can happen.

Yep, I always work on the principal that a GUID may be duplicated so I add Ticks since the Epoch or something like that to my GUIDs because Ticks should only ever increase. The chances of getting the exact same ticks in milliseconds AND a duplicate GUID are not gunna happen!
you're welcome

You don't need to add a surrogate key containing a “tick”, because GUIDs already have such a field.
|
|
|
|
|
Adding it where?
Guids aren't always "increasing". so adding an increasing value to a random value doesn't mean you won't get a duplicated outcome.

I thought developers were supposed to be logical!
Your statement screams "Does not compute, Will Robinson!" at me!
The minimum, of course, is two.

While you smart arses are arguing the toss I've just seen another duplicate GUID pass by. 
If there is one thing more dangerous than getting between a bear and her cubs it's getting between my wife and her chocolate.

Did it include the characters S, S, N, N, L, L, L, I, I, E, E, E, and E?

I'm sure our dearly departed forum friend Leslie would confirm that.

You sure?
They are a lot like snowflakes: if you look at the fine detail they aren't the same.

Quote: They are a lot like snowflakes:
Funny you bring that up. Recently a scientist claimed to have found many duplicates after cataloging many, many snowflakes.
Of course they aren't unique.
There are only 10 types of people in the world, those who understand binary and those who don't.

Does that include artificial snowflakes?  
|
|
|
|
|
To be fair though, snowflakes are only 64 bit

Yikes! It's like encountering your doppelgänger in the street.
I may not last forever but the mess I leave behind certainly will.

With GUID we talk about probability not certainty.
Even we have a GUID generator that really generates unique id, at the moment we run it in multiply locations we lost event the theory of uniqueness...
I'm not questioning your powers of observation; I'm merely remarking upon the paradox of asking a masked man who he is (V).

I still try discourage everyone from using GUID's if it's not truly necessary.
1. Waste of disk space, if an 32bit integer is sufficient why use a GUID?
2. Waste of processing power, more expensive to create, more expensive to compare against etc.
3. GUID is way more difficult to read for humans
Sure there are uses for it but in most cases you're perfectly fine without them.

So what? IDs are meant to be meaningless; so that's a good thing. Even with integers you'll likely wind up just copying-and-pasting anyway.
Or do this:
00000000-0000-0000-0000-000000000001
00000000-0000-0000-0000-000000000002
00000000-0000-0000-0000-000000000003
00000000-0000-0000-0000-000000000004
00000000-0000-0000-0000-000000000005
