Would you believe I was watching a third rate TV program about the retailer TK Maxx and they discussed Hashing.

Yes hashing.

They take one item in multiple sizes and hash them between clothes rails, i.e. they split them into individual items and put one item on each rail.

The do this to foster FOMO, if you can only see one option for your size, then you feel more compelled to buy it.

But then I realised that is what Bitcoin mining does when it hashes. It splits a message up into equal parts, encrypts each part to a fixed length and then puts it back together.

Same as corned beef hash, which splits corned beef, onion and potato into equal parts, then recombines it.

I finally understood the significance of hashing by watching a program about shopping 😂
