It just goes to show you that no matter the capabilities of the medium of the day, people will do anything to expose their genitalia.

From Pompeii[1] to LEGO Universe. Gosh.

Although I have to admit that I've been puzzling about this kind of problem in my spare time because it is a very difficult problem to solve with plain algorithms.

Which makes me ask, why don't they just separate the kids who draw dongs into a separate pile and only let them interact with each other? Or something like that. Something like GTA V's "cheater pool" [2] or HN's hellbanning.

Some of the Pompeii erotic art may have had a practical purpose. I saw a documentary about Pompeii that mentioned erotic murals at a public bath. These were not the "normal" kind of erotic scenes you would find in Pompeii or other Roman cities. They were things that would be considered shocking and perverted by even Roman standards.

These murals were in an area that was the Roman equivalent of a locker room, where bath attendees would leave their clothes. Archaeologists speculate that the shocking murals were memory aids--a customer could remember where they left their clothes by remembering the shocking perverted scene on the mural above that section.

This is plausible. Shocking or unusual things are easier to remember, so this would have been more effective than just numbering or lettering the sections of the storage room.

This is also why people around my age (mid 50s) probably have an easier time remembering the resistor color code. The mnemonic I learned 40 years ago is shockingly racist, violent, and sexist--and so impossible to forget. The mnemonics taught to kids nowadays are boring and easy to forget.

I'm in my early 30's and I still remember the exact mnemonic you speak of. Sorta shamefully, at that.

Just turned 30 and by the time I heard it s/Black/Bad/ happened so it was only violent and sexist. I heard it from a older professor in my early 20's and was quite shocked that it was a thing, but I remembered it.

Oh, I had only heard "Bad", but goodness, I didn't think it would be worse.

The "Black" version is interesting, because not only is it more offensive (and so probably slightly easier to remember), it doesn't require a separate way to distinguish the colors black and brown so there is less to remember.

Never heard about that the resistor color code has another meaning beside being a color code. Though I would have preferred a simple Ohm value on 4 sides instead of the code.

Inspection is trickier with printed values, even if you have four sided printing.

Reliable printing on curved surfaces wasn't possible at the time when "miniture" resistors were being produced, and a paper wrapper would be an undesirable extra element.

I've always struggled with resistor colour codes, but after I looked up what you were talking about I think I have it instantly memorized. Better not let anyone know, though.

Ha ha ha

I just memorized the sequence as a 'word'. Like the beginning of each word, so would be like BlaBroReOraYelGreBluViGraBla (but not in English, so it's shorter, since I take only the first letter of some of the colors, so maybe BlBROYGBlVGBk)

I didn't use a phrase because I made this mnemonic myself.

Another electronics mnemonic I came up with, which is the Cathode and which is the Anode of a diode. So if you see it's something like this: --->|--- the left side is the Anode (since it looks like an A) and the right is the Cathode so it looks like a K (mirrored in this case)

I do not remember resistor color codes and I could use a violent and sexist mnemonic if you don't mind sharing.

In astronomy, the spectral classes of stars are "oh be a fine girl, kiss me" but even that mnemonic is inappropriate for some classrooms these days.

Let me save you some googling :

The one we are talking about is in the list.

Apparently some teacher was jailed for teaching that in class.

The mnemonic is listed here if you are as curious as I was...

I know some contemporary fancy places that have naughty art in the gents. I think it's mostly to be amusing. It's usually in contrast to the formality of the rest of the place.

> why don't they just separate the kids who draw dongs into a separate pile and only let them interact with each other?

Ha, I can't imagine any issues with that from a PR perspective at all.

Yeah, in a kids game you'll probably get an awful lot of complaints from parents when they find out that their child is suddenly only capable of entering games with dongs as the primary focus.

poor kid makes a rocket ship ends up in dong world.

This may be the most entertaining thread I've ever seen on HN.

or on the planet Porno...

Because it would group all the kids who obviously don't have parental supervision into one place where people are already talking about and/or showing fake dongs.

And then some sicko comes in and wants to talk about and/or show their own.
