My first attempt at computational line art!
This image is a representation of a sha256 hash of an input string, my name. Each ring represents 4 characters of the hash, and is the binary representation of the character's ascii value.
A hash is a transformation of an arbitrary-sized value into another value of fixed size. Hash functions that are one-way, i.e. cannot be reversed, are the basis of modern cryptography and security on the Internet. Given this image, you wouldn't be able to reverse it to find out the original string, but every time I run the hash on the same string it will output the same value.
The next step is to load this into my #AxiDraw and plot it on some actual paper!

One of my favorite usages of my Tiles, again when I used to travel.
I never got on the Tile train, but kind of feeling like I was missing out now! -
I'm on my way home! I completely forgot you're in SF otherwise I would have suggested we get lunch! 😭 Next time! -
Unexpected side benefit of #AirTags is confirmation that your checked luggage is in fact on the plane with you

#indieweb.org I'm not sure if endearing,or perhaps just byproduct of the thing it is, it's intent/counterculture; but the number of dead links, and stale content is a tad disheartening.
It's a wiki! Please feel free to replace stale links with their archive.org versions! -
