Back in the old days, the old Australian $100 bill was of a sort of dull palete, grey with swirls of pastel shades. If you photocopied it on a really good black and white copier and tried to pass it off in a dark place with irregular lighting, like a night club, I'm told you could do so.

I'm guessing forgers know about GIMP and are willing to endure its awful UI ;)

Presumably - GIMP doesn't check, and they'd have to make the source code public if they wanted to put the checks in (and then people would just make a version with out it!)

The story about the Parmesan Sikhs sounds very American. The United States is covered with clusters of immigrants and immigrant descendents which nucleated around first arrivals. My favorite was the discovery that 85% of the donut shops in the entire state of California were run by Cambodians.

That's pretty awesome. And yes, one of the great thing about the US is the sheer variety of immigrants. It's a shame it's more closed down nowadays.

I recall reading a story to my toddler children about barnyard animals and even the cows were male. It was so wrong it was amusing. Sort of.

[andrewducker]

Sort of indeed :->

I would _love_ to know what's going on that causes this. I'm assuming it's people making assumptions and not checking- defaulting to "His" because they don't care and nobody told them. But surely there's _some_ quality control going on.

Banknote codes:
If Kuhn had just used the 'select area' tool to only colour copy the area of the note, it would have reproduced, as this instruction overrode the default. He could also have used the multi-set to print 3 at a time on one a4, front to back. Also worked only copying in CMY, with no black (don't remember why this worked probably due to same override).

Back in the early 90's a wide selection of change machines (especially for parking meters) didn't check US notes for colour, all one needed was a close enough weight of paper and a well aligned B&W copy. They were like this for quite a few years.
