I’ll see your raise, and up it:
Please,
I always see those videos where people give kids a walkman or a rotary phone and ask them to figure out what it is or how it works. I'm imagining some medieval merchant handing me an abacus and laughing because I can't figure it out.
It's little endian, so the beads on the far right are used to outnumber the big endian beads at the top on the woke left. After several computations, the middle section is just gone
Tried reading about endianness once. Pretty sure it can't be dumbed down enough for my brain.
You know how some languages write left-to-right, and some rught-to-left? Endianness is that, for numbers.
Or another analogy is dates: 2025/12/31 is big endian, 31/12/2025 is little endian. And 12/31/2025 is middle endian. Which makes no sense at all because the middle is, by definition, not an end.
I stand corrected. No idea what I was reading (several years ago), but whatever it was made it seem way more complicated. Maybe it was just an explanation from somebody who didn't know.
Likely it was being explained in the context of binary number representation as it is primarily important in computer architecture. If you're not already familiar with that then it was probably confusing explained in that context.
Depending on whether the order of binary comes from the left (Big Endian) or from the right (Little Endian), the binary number of "1010" can equal 5 or 10
Ouch. I had to learn endianness once to solve a real life serialization bug. It sucked. I learned it for just long enough to correct the code for the corner cases involves, and then slept and forgot everything about it.
Hint: each bar has five beads, with a 2 bead multiplier above
Young whippersnappers.
You kids don't know how good you have it!
At least you have hands! I had to get my fabricated from the town blacksmith.
Ooh ooh ooh?
Fun fact, the Romans would never have labeled their abacuses like this. It would have made calculating very difficult; they effectively worked with modern numbers in bead form, and then used the famous numeral system just to record the results.
Don't buy copper from this guy, it's low-quality and your messenger will be treated with contempt.

This. this is my childhood. Digging through discount bins at blue light specials in Kmart for cartridges and copying BASIC line by line from a magazine and recording it on cassette tape so we could play Yahtzee on the TV.
We had one of those in school. One per classroom. We had one educational game on it. Since there was only one, they would sit us down at it in pairs and we'd get 5m to play on it. I think I got to use it maybe three times in a given year.
My buddy still has one of those in his garage.
My brother in Munchman, Alpine, and coding racist stuff out of the book.
