Today I learn I write my 7's the same way the guy who draws Wizard of Id does.
... oh crap... is THAT where I picked that 7-slash line from???
@JulieSqveakaroo@dragon.style @Austin_Dern@blimps.xyz in my case I picked it up from a mystery story in Boys Life in which part of the solution hinged on realizing who would have written something because of a barred seven. After which I thought to myself, "That sounds nifty, I think I'll do that from now on." I probably got the seed of my conlang interest from another issue.
It does make it very easy for me to determine if I wrote a note, or not... no one else around here seems to write like this...
@JulieSqveakaroo@dragon.style @Austin_Dern@blimps.xyz I also started regularly slashing my zeroes once I started working with computers because they don't take swapping Os and 0s very well. (Which I learned early on in the single digit age when I tried typing a basic program into an Apple IIe and decided the person who wrote the book couldn't possibly have meant to write gosub and after some thought decided it was obviously gosubmarine. Strangely the program didn't run after that.
Also, Apple //c was my learning point.
@JulieSqveakaroo @LilFluff Ah, yeah, that's got to be an influence on me too. I didn't stick with slashes through 0's (too much of a mathematics nerd not to notice that made things the null set), but it did prime me to thinking about how these things are just symbols and you can change them for convenience. (I also put a little vertical serif at the end of square root signs, to indicate the end of the expression underneath them.)
My track was Color Computer 1 -> Commodore 64 -> 128.
Now, as a machinist, the o with the slash through it is a symbol calling out the diameter on a print size.
