My wife and I are working on a math/science/CS-inspired jewelry: pieces that stand on their own aesthetically but have a hidden meaning.

We currently have two styles: lambda calculus based pieces (we depict the Tromp diagram) where we have Y-Combinator earrings (well, strictly speaking they are one beta reduction away from Y-combinator. Aesthetic oblige) and a pendant depicting a lambda expression computing Graham's number. The other style is quantum computing circuits, based on quantum computing research my brother (a physics professor) is doing: a pendant that is actually a non-local controlled-NOT gate.

I wrote a tiny DSL to describe the jewelry pieces, and an interpreter to produce CAD files. We then either 3D print them or have them produced by lost-wax.

We have our pieces in consignent in a jewelry store, and are working to put them in a museum store.

Marketing is the hardest part. Ideas are welcome.

We are 200% out of our comfort zone (and love it): I know nothing of front end dev, payments, or anything like that. The diamond district in New York is a neighborhood we normally actively avoid, but if you are forced to go there it is fascinating (people examining diamonds on the corner of the street, others in fur coats in summer straight out of a mafia movie...), and especial marketing. Jewelry is a completely saturated business (luckily we are not doing this to pay the rent); we think we have a unique angle, but we are still figuring out the target audience (if there is one), how to advertise, etc.

Any ideas on marketing are welcome.

We have not really started advertising, but my wife is (very) often complimented on the jewelry when she wears it and that has led to a few sales.

What I often ended up doing is asking it to draw 3 labeled arrows X,Y,Z. So I could tell it to orient along the XY labeled arrows (which are in reality YZ, but whatever).

Also used AI to design an online store (I'm not a front end dev). It's amazing to see my wife (non-technical background) tweak the web-site using claude code.

End result: an online store where we sell jewelry pieces that actually are lambda-diagrams (Tromp diagrams) that compute Graham's number, or of the Y-combinator (well, technically it's just a fixed point operator, one beta reduction away from the Y-combinator. But Y-combinator was not aesthetically pleasing from a jewelry point of view)

store: Built a tool to help design cs/science inspired jewelry in CAD. I wrote a DSL to describe the jewelry, and had an LLM write the interpreter to generate a CAD file using cadquery (note to self: LLM suck at 3d reasoning). I would not have had the time to do this without AI.

Galileo had just build the first ever telescope and he describes what he has discovered: there are incredibly more stars than can be seen by the naked eye; Jupiter has satellites; there are mountains on the moon and he has figured out their height from the length of their shadows... The book is full of the quiet excitement of a man who has discovered a new world, and seen what no man had seen before.

In general I would not worry to much about the performer, but it might be interesting to listen to different interpretations of the same piece, particularly from composers with very idiosyncratic styles. On youtube, Ashish Xiangyi Kumar (https://www.youtube.com/c/AshishXiangyiKumar) has videos of pieces (mainly piano solo) interpreted by different artist.

I googled a bit and found this amazing gem: it uses lex to create a custom C program that does just what you want. Posix compliant. All wrapped up in bash function.

If you specify many replacement rules in sed, it will run in O(num_replacements * num_lines). You should be able to use a state machine to do it in O(num_lines), so I google a bit and found this amazing gem: https://unix.stackexchange.com/a/137932

tl;dr: it uses lex to create a custom C program that does "just what you need", compiles it, and runs it on your input. The whole thing wrapped in a bash function. Bonus: it's POSIX compliant.

I wish modern system where still designed like that...

E.g. instead of:

  i=0
  StartLoop:
  i+=1
  do_stuff_0
  do_stuff_1
  do_stuff_2
  do_stuff_3
  if i<N goto StartLoop

  i=0
  StartLoop:
  i+=1
  do_stuff_0
  do_stuff_1
  if i<N goto StartLoop in 2 instructions
  do_stuff_2
  do_stuff_3

So it looks like a standalone git client rather than emacs.

I'm an emacs user, so I would never use this, but it's just a thought.

In the paper, they say that they double the dilation factor up to a limit and then repeat: 1, 2, 4, ..., 512, 1, 2, 4, ..., 512, 1, 2, 4, ..., 512

The doubling of the dilation factor makes sense to me, but what is happening with the "repeat" part? I don't understand what they are trying go do. Wouldn't make more sense to continue doubling?

Consider the square of (length + with + height). The sum of the diagonal terms is the square of the distance between opposite corners, the sum of the off diagonal terms equals half the area of the boxes. We can show that both these terms are smaller for the innermost box.

It’s obvious for the diagonal terms, as the opposite corners of a box are the two points of the box that are furthest apart. So the opposite corners of the inner box must be separated by less than the opposite corners of the outer one.

For the cross diagonal terms: take axes that are aligned with the inner box. Consider the parts of the outer box that would be projected on the inner box if you projected either on the x&y, x&z, or y&z planes (i.e. you project on the faces of the inner box). These six pieces of the outer box don’t intersect, and each of them is larger than the face of the inner box on which they project. So this part of the outer box has an area bigger than the total are of the inner box. QED

So as the frequency with which people arrive approaches 1 in 10 minute (from above), the average wait time will increase dramatically, reaching infinity at 1 person / 10 min.

    That time of year thou may'st in me behold
    When yellow leaves, or none, or few, do hang
    Upon those boughs which shake against the cold,
    Bare ruin'd choirs, where late the sweet birds sang.
    In me thou see'st the twilight of such day,
    As after sunset fadeth in the west,
    Which by-and-by black night doth take away,
    Death's second self, that seals up all in rest.
    In me thou see'st the glowing of such fire
    That on the ashes of his youth doth lie,
    As the death-bed whereon it must expire
    Consum'd with that which it was nourish'd by.
        This thou perceivest, which makes thy love more strong,
        To love that well which thou must leave ere long.
