@Daojoan Keyboard is a bit more complex (eg there are reasons typewriter is all one one row...)

Obvious other ones
- The 4'8 and a bit standard railway gauge was basically arrived at by network effects and nearby mining railways. It's way too narrow but we persist in running trains over it at high speed because it's easier than fixing the track width
- Long summer school holidays in many countries so kids could help with the harvest
- The floppy disk icon for save

@Daojoan the one that stays with me most is learning that crash test dummies were originally mostly adult male cadavers, and then when they replaced them with actual dummies, they were still mostly only male body types. I think they only evolved how they test vehicles in the 1990s, maybe, with a greater variety of test dummy shapes/sizes.

@Daojoan Right on Red

As I vaguely recall, the standard 80 character column width for used terminals and recommended maximum line length for code (e.g., PEP-8) is a holdover from the IBM punch card standard that specified 80 columns, which is itself a holdover from early 19th century loom technology for fabric weaving.

@Daojoan This is not really true. QWERTY was (most likely) designed as a result of feedback from mechanical telegraph operators, in order to make their typing easier: https://www.smithsonianmag.com/history/the-qwerty-keyboard-will-never-die-where-did-the-150-year-old-design-come-from-49863249/

To the extent that the "jamming" story is true (to some extent, it is; jamming was a mechanical concern) the way that a layout avoids jamming is by placing letters that frequently occur adjacent to each other on opposing hands, which *is* better for operator ergonomics too.

@Daojoan Try calling a folder "aux", "con" or "lpt" on Windows. Y'know, for auxiliary files, the opposite of "pro" arguments, and life-pro-tips.

@Daojoan

Screen characters have various standards for encoding those glyphs in binary, the most common are ASCII and Unicode. But along with the visible characters there are also codes to represent things like indentation (the tab character \t) or a new line (\n).

These codes used to control machinery. \n would roll the paper down in the teletype printer, and \r would return the print head to the start of the line.

@Daojoan lightheartedly pointing out, this is dangerously close to being a #nickland post

I switched to Dvorak keyboard layout and all was great. But the world didn't change with me 🥺

@Daojoan

You are obviously unaeare of several dozens other existing keyboard layouts.

@Daojoan Try to rename your harddisk/SSD to letter A: or B: ...

@Daojoan Oh man don’t get me started.

“Special characters”
File extensions
File compression

@Daojoan please no, you’ll bring out the Dvorak crowd

‘Dvorak is more efficient, people who learn Dvorak can type faster’ I see this a lot, but the word per minute increase is because people who learn Dvorak are spending time *formally learning to type!*

Neither one is ‘more efficient’ than the other. How would you even measure that, it’s all so silly.
