I was researching an oddity that came up at work yesterday. A co-worker said you can’t color copy cash. I was dubious, so she proved it. What the… Huh? So I asked google.
One of the links pointed me back here, so I clicked it. It looked different on my browser so I check the link and whaddaya know? I found that there is an archive of ancient dopeness. Non-postable, but lots to read, so yay!
I can’t find a link here to access it, so I will have to google it again next time I’m bored and I have time.
I can’t believe you’ve been hiding cool old posts from me.
Note that those threads still all exist in their normal, postable (unless they’ve been locked) forms, too. At the top of the archived thread, there’s a link to “View Full Version”. In this case, that leads to this thread, which you could post to just like any other zombie (but please don’t, unless you have substantive new information to add).
When I encounter an archived version of a thread in a search, I usually view the full version anyway, just because a lot of the coding gets lost in the archived version. In particular, quote tags don’t work, which can make a mess of a conversation.
It’s generally rather pointless, as you can get to the non-archived version, but it’s a feature that’s on by default in vBulletin, and, of course, that’s not going to be turned off here.
In another system, old posts might be deleted automatically, and thus only the archived versions would exist–unable to be altered or resurrected.
That archive is only the printable version of these boards but with the forums set as “show oldest topics first”. If you go to the very last pages (in any of those forums), you’ll reach threads that are on the front pages right now.
Because the threads are listed in oldest first order, I discovered something interesting when I looked at the Pit. The inaugural thread announcing the creation of the Pit had a discussion of the use of profanity that began in the 6th post. This discussion made it pretty clear that profanity was OK but that there would be some limits. Thread here.
As for the original question, about how copiers recognize and refuse to copy money, the words you need to google are EURion constellation. There, you’ll find out exactly how this works – not just for American money, but for many other countries’ money too. (Upon quickly skimming the old thread mentioned above, I didn’t see it mentioned. But I’m almost sure it’s been discussed in a thread here somewhere.)
ETA: It wouldn’t surprise me if modern copiers not only refuse to copy paper money, but if you try, they will send an immediate report of your attempt to your local Secret Service office. Welcome to the all-connected Internet Age!
