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.

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.

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.

[swords-n-spindles]

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

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).

Tutorial and or tips in color studies?

Hi there! Sorry to keep you waiting on this ask!

I do have another post about landscape painting which overlaps slightly with this. But here I’ll talk specifically about the observational color studies I like to do. Other artists might have different ways of approaching them (and I still have a lot to learn myself), but these are some of the ideas I’ve found useful.

1. Don’t seek perfectionObservational color studies are just that – studies. Sketches. Note-taking to reference later. They’re not supposed to be complete paintings, so you shouldn’t feel pressured to make them “perfect”. I like posting them sometimes (and hopefully you like seeing them) but there are TONS of messy, scribbly studies I haven’t posted anywhere. They’re primarily a tool to help me learn, and if messy studies help me learn, so be it!

2. Simplify your shapesSo how do you avoid getting overwhelmed and lost in the details? Focus on the BIG IDEA. Decide what is most important to include in the study and leave out everything else. Start with big shapes, and add details at the very end, if you have time. Personally, I’m often interested in the sky and the color clouds become when light passes through. So I might make the study about the clouds and ignore buildings/details on the ground. or I’ll add only a very simple ground plane. Other times, I’ll rearrange a composition to include all the important information (like making an object bigger or smaller, or bringing two objects closer together).

3. Step by stepIt helps to find a good workflow, especially when you have to quickly prioritize what information to include. This is relevant especially when you’re painting something like a sunset, when the light changes RAPIDLY and you’ll have only 3, 4, 5 minutes to put your colors down. For me, this usually means I build my study from background to foreground: sky, clouds, ground plane, background shapes, foreground shapes. Since I work on iPad Pro, I also keep those parts separated out into layers. In the case of those quick sunset studies, I also observe the parts I haven’t painted yet in case the lighting changes enough that I’ll need to work from memory.

4. Some fundamentals to keep in mind:

Value structure: Even though these are color studies, value plays a major role in the colors you’re observing. Pay attention to the difference in value between subjects. Sometimes this can solve color-related problems when your study seems “off” somehow. (For example, maybe that sky isn’t as light as you think it is? A darker value might mean painting a more vibrant color.)

Lighting setup: Identify the different light sources in the environment. Is it cloudy and overcast? Sunny? Are you indoors, with multiple different light sources? A little study about lighting theory can really help you know what colors to look for in different lighting conditions. For example, in overcast light, you’ll see more of the objects’ local color, while in bright sunlight you’ll see a strong direct light (the sun), blue diffused light on shadows and top-facing planes (from the blue sky), and a warm bounce light (from sunlight reflecting off the ground). Will forever recommend James Gurney’s book “Color and Light” for help learning this.

Materials: Different materials reflect light sources in different ways. Being aware of how light passes through or reflects off different materials can help you understand the colors you’re seeing.

5. Going beyondAs you become more comfortable making observational studies, the more you might wish to push them even further by not just copying from life but communicating a feeling. A few ways you might accomplish this:

Exaggerate your colors. Suppose you see a hint of color you wouldn’t normally expect to find, such as notes of purpose or red near the horizon of an otherwise blue sky. Try making it brighter/bolder than you really see it. Bump up the saturation, maybe. This is a delicate balance, as you don’t want to exaggerate to the point where the colors become garish. But putting emphasis in certain places can remind yourself, or show whoever’s looking at your study, that you found certain details interesting.

Think about mood. A color script from an animated film follows the emotional beats of the story. As you’re making your studies, consider: how does this moment feel to me? Take a cloudy scene, for instance. Is it cold and miserable? Windy, full of movement and energy? Calm? Dark and ominous? A moment of anticipation or hope with the clouds about the break apart? Each of those conveys a completely different mood. So you might decide upon one and push your color palette to support that idea.

Don’t just copy: communicate. This last one is a bit of an abstract idea I need an example to explain:

This sunset study here gave me difficulty because it involved not just color but the properties of light. The sun didn’t actually appear white to me - it appeared a bright red/pink color, glowing brighter than the sky around it. But that wasn’t something I could reproduce, because if I only painted the color, it wouldn’t appear glowing and would blend into the rest of the sky. Instead, I had to think critically: how do I communicate the brightness of this sun? In the end, I opted to make the sun white, with the color I actually observed the sun to be surrounding it.

On my Instagram, I’ve posted a lot of process videos to accompany my studies, if that interests anyone! They’re always second image on the studies’ posts.

I hope you find these thoughts helpful!
