royai is about the pining…(but it’s mostly about the paperwork)

So the other night during D&D, I had the sudden thoughts that:

1) Binary files are 1s and 0s

2) Knitting has knit stitches and purl stitches

You could represent binary data in knitting, as a pattern of knits and purls…

You can knit Doom.

However, after crunching some more numbers:

The compressed Doom installer binary is 2.93 MB. Assuming you are using sock weight yarn, with 7 stitches per inch, results in knitted doom being…

3322 square feet

Factoring it out…302 people, each knitting a relatively reasonable 11 square feet, could knit Doom.

Hi fun fact!!

The idea of a “binary code” was originally developed in the textile industry in pretty much this exact form. Remember punch cards? Probably not! They were a precursor to the floppy disc, and were used to store information in the same sort of binary code that we still use:

Here’s Mary Jackson (c.late 1950s) at a computer. If you look closely in the yellow box, you’ll see a stack of blank punch cards that she will use to store her calculations.

This is what a card might look like once punched. Note that the written numbers on the card are for human reference, and not understood by the computer.

But what does it have to do with textiles? Almost exactly what OP suggested. Now even though machine knitting is old as balls, I feel that there are few people outside of the industry or craft communities who have ever seen a knitting machine.

Here’s a flatbed knitting machine (as opposed to a round or tube machine), which honestly looks pretty damn similar to the ones that were first invented in the sixteenth century, and here’s a nice little diagram explaining how it works:

But what if you don’t just want a plain stocking stitch sweater? What if you want a multi-color design, or lace, or the like? You can quite easily add in another color and integrate it into your design, but for, say, a consistent intarsia (two-color repeating pattern), human error is too likely. Plus, it takes too long for a knitter in an industrial setting. This is where the binary comes in!

Here’s an intarsia swatch I made in my knitwear class last year. As you can see, the front of the swatch is the inverse of the back. When knitting this, I put a punch card in the reader,

and as you can see, the holes (or 0′s) told the machine not to knit the ground color (1′s) and the machine was set up in such a way that the second color would come through when the first color was told not to knit.

tl;dr the textiles industry is more important than people give it credit for, and I would suggest using a machine if you were going to try to knit almost 3 megabytes of information.

It goes beyond this. Every computer out there has memory. The kind of memory you might call RAM. The earliest kind of memory was magnetic core memory. It looked like this:

Wires going through magnets. This is how all of the important early digital computers stored information temporarily. Each magnetic core could store a single bit - a 0 or a 1. Here’s a picture of a variation of this, called rope core memory, from one NASA’s Apollo guidance computers:

You may think this looks incredibly handmade, and that’s because it is. But these are also extreme close-ups. Here’s the scale of the individual cores:

The only people who had the skills necessary to thread all of these cores precisely enough were textile and garment workers. Little old ladies would literally thread the wires by hand.

And thanks to them, we were able to land on the moon. This is also why memory in early computers was so expensive. It had to be hand-crafted, and took a lot of time.

(little old ladies sewed the space suits, too)

Fun fact: one nickname for it was LOL Memory, for “little old lady memory.”

I mean let’s also touch on the Jacquard Loom, if you want to get all Textiles In Sciencey. It was officially created in 1801 or 1804 depending on who you ask (although you can see it in proto-form as early as 1725) and used a literal chain of punch cards to tell the loom which warps to raise on hooks before passing the weft through. It replaced the “weaver yelling at Draw Boy” technique, in which the weaver would call to the kid manning the heddles “raise these and these, lower these!” and hope that he got it right.

With a Jacquard loom instead of painstakingly picking up every little thread by hand to weave in a pattern, which is what folks used to do for brocades in Ye Olde Times, this basically automated that. Essentially all you have to do to weave here is advance the punch cards and throw the shuttle. SO EASY.

ALSO, it’s not just “little old ladies sewed the first spacesuits,” it’s “the women from the Playtex Corp were the only ones who could sew within the tolerances needed.” Yes, THAT Playtex Corp, the one who makes bras. Bra-makers sent us to the moon.

And the cool thing with them was that they did it all WITHOUT PINS, WITHOUT SEAM RIPPING and in ONE TRY. You couldn’t use pins or re-sew seams because the spacesuits had to be airtight, so any additional holes in them were NO GOOD. They were also sewing to some STUPID tight tolerances-in our costume shop if you’re within an eighth of an inch of being on the line, you’re usually good. The Playtex ladies were working on tolerances of 1/32nd of an inch. 1/32nd. AND IN 21 LAYERS OF FABRIC.

The women who made the spacesuits were BADASSES. (and yes, I’ve tried to get Space-X to hire me more than once. They don’t seem interested these days)

This is fascinating. I knew there was a correlation between binary and weaving but this just takes it to a whole nother level.

moiraecrochet

I’m in Venice, Italy several times a year (lucky me!) and last year I went on a private tour of the Luigi Bevilacqua factory. Founded in 1875, they still use their original jacquard looms to hand make velvet. Here are the looms:

Here are the punch cards:

Some of these looms take up to 1600 spools. That is necessary to make their many different patterns. Here are some patterns:

How many punchcards per pattern?

This many:

Modern computing owes its very life to textiles - And to women. From antiquity weaving has been the domain of women. Sure, we remember Ada Lovelace and Hedy Lamarr, but while Joseph Marie Jacquard gets all the credit for his loom, the operators and designers were for the most part women.

the-fibre-stuff

I’ve seen this cross my dash a few times, but I’ve never watched the video before. Maybe I just didn’t pay attention when I was a kid, but I don’t remember ever seeing just how the Jacquard loom works. I just knew that the punch cards controlled which threads were raised. It’s cool to see the how, not just the what.

Don’t hide this in the tags, @drylime :D

iplaywithstring

I am never not amused by the overlap of textiles and technology. Also the fact that a huge number of fiber arts people I know are either in tech or math themselves or their partner is (myself included - husband is a programmer).

M1: The Crab Nebula : The Crab Nebula is cataloged as M1, the first object on Charles Messier’s famous 18th century list of things which are not comets. In fact, the Crab is now known to be a supernova remnant, debris from the death explosion of a massive star, witnessed by astronomers in the year 1054. This sharp, ground-based telescopic view combines broadband color data with narrowband data that tracks emission from ionized sulfur, hydrogen, and oxygen atoms to explore the tangled filaments within the still expanding cloud. One of the most exotic objects known to modern astronomers, the Crab Pulsar, a neutron star spinning 30 times a second, is visible as a bright spot near the nebula’s center. Like a cosmic dynamo, this collapsed remnant of the stellar core powers the Crab’s emission across the electromagnetic spectrum. Spanning about 12 light-years, the Crab Nebula is a mere 6,500 light-years away in the constellation Taurus. via NASA

“It’s a hospital not a hotel.” is one of the shittiest fucking things I’ve ever seen commented under a patient complaining about their care. No, you’re right. It’s a hospital, not a hotel. You’re paying way more to be there and you’re likely having one of the scariest experiences of your life and you’re probably overwhelmed, in pain, unwell, having a mental crisis OR otherwise stressed. The least they can fucking do is treat you like a human being. They should you your basic human needs like water and food.

squagel

Cool but when healthcare workers say this, they are referring to patients and/or family members who are extremely nitpicky about said food and water, who hit the call button for every little thing and expect the nurses to come within 30 seconds, and who act like being there means having every whim catered to. Yes, hospitality certainly belongs in a hospital environment, and yes, you should expect your food, water, and bedding to be clean and for your care team to be compassionate, but not to the extent that you should expect to be waited on hand and foot. It’s not realistic and very rude. Being lonely or scared due to being hospitalized—which I totally understand, having been a patient before—is not an excuse to be mean to the people who are taking care of you.

The hoops that you jumped through to interpret this post instead of just stopping and thinking “Yeah. There is a systemic problem with patients being dehumanized and neglected especially the elderly, chronically ill, the nonverbal and patients of color.” I have literally only seen that phrase used to silence people. I have never seen it used towards someone who was making an outrageous insane demand. Just absolutely rational things like “I wish the hospital would stop trying to give me food I’m allergic to.” and “The nurses treated me with a condescending and uncomfortable attitude that made it difficult to ask for help when I really needed it.”

squagel

And I’m saying that where you’ve seen that phrase used maliciously against people in vulnerable populations, I’ve seen it used by overworked healthcare professionals—usually nurses—in the context of patients/families making outrageous demands or complaints, such as being “too late” with a water pitcher refill even though there was a code blue happening in the room next door. That’s not to say that healthcare workers are above reproach and couldn’t use an attitude adjustment when it comes to caring for the kinds of patients you mentioned, though.

they concluded that the rats were having fun partially bc the rats voluntarily initiated games, hopped around joyfully and teased researchers by pretending to come close and then skittering away. rats are Very Good

These scientists are getting grant money to play games with rats all day and that is just, living the dream.

this is so accusatory. those vile children never learned cursive!!! bitch whose responsibility was it to TEACH THEM???

magspag

I read that as more celebratory than accusatory. The curse has been broken

3liza

cursive is extremely useful for anyone who writes with liquid ink pens, anyone who enjoys taking handwritten notes quickly and with lower stress on the joints, and anyone who wants to read handwriting from the historical record. these are all really common situations to be in even for civilians, even in 2022. flipping over the photographs from your grandparents’ album and not being able to read what they wrote on the back is a bummer. i understand superficially the hatred of cursive and the condemnation of it as useless, but it is misguided. having hundreds of years of human output made illegible to you in a single generation is actually pretty alarming from a historical access standpoint. people should be mad they were not taught to read one of the major languages used by their recent ancestors.
