It's from 2021: Moiré no More (https://newsletter.shifthappens.site/archive/moire-no-more/).
Here's 2009: https://web.archive.org/web/20090307125843/http://www.baseca...
if you go back to 2007 you can see the same structure in a plainer presentation; it's easy to see how they went from one to the other: https://web.archive.org/web/20070831191822/http://www.baseca...
Pretty interesting!
For mine, I make fields by superimposing a bunch of harmonic functions. By playing with different periods, phases, etc. you can get some cool patterns that look irregular and interesting, though I think they have a different feel from some of these noise-based examples.
I also make some fields by using sources and sinks: a collection of points that push out or in. You don't need that many to make an interesting field.
For collision detection I use the trick @danbruc mentioned in another comment: I draw to an offscreen canvas, and just check pixel color to see if a trace is already there. It's probably very costly in terms of memory as a data structure, but it's very convenient :) https://www.instagram.com/p/CMi4QcXn6_y/?img_index=1
For me the interest has come in coloring the lines — by deferring rendering until after the path has been plotted, you can color different traces according to how long they are, how much they curve or change, etc. which can reveal interesting bits about the flow structure. https://www.instagram.com/p/CMvqZjkHYpV/?img_index=1
Thanks for this great writeup @tehrash, the explanations and examples are great!
Computer, generate a list of applications where technology like this should absolutely not be used.
This seems terrifying — wouldn't this, for example, synthesize identifying details about motor vehicles not present in the sample, drawn from training data? About people? Etc etc
This sounds awesome for making a consumer mapping product feel higher quality. Hell, it could even serve an anonymizing function that is pro-privacy ("a roof" not "your roof"). But it feels incredibly reckless to direct this toward those listed industries.
People in surveillance and forensics etc. should be confronted with the limits of the quality of the data they are using, we should not try to synthesize extra confidence in their analysis by making the images seem higher quality than they are.
I use this all the time to handle things like text, images, pdf etc to open them in non-default apps. I find this a lot easier than dealing with the dock. Hope this helps!
Like, even on cut or stamped grills, how much could performance be improved by e.g. sandblasting the finished piece from one or both sides and taking down the edges a bit?

This is a very interesting story, and it's great to see Okuda acknowledged for her work and hear more details about that. Casio is a great example of a company that I just took completely for granted growing up and seemed completely opaque and impersonal to me. It's so cool to see the individuals that are behind all of those things. My brothers and I had an MT-40 when we were kids, I loved playing with it, and had no idea it had an impact like this.
I'm not trying to discount the take-away that the fees are very high regardless of the projection basis, but I think it's important to understand the difference. If these criticisms are not clearly reasoned or communicated, I think that fuels the perception in the financial community that these complaints are hysterical and unfounded and should be dismissed.
> "Over the last 10 years, the return on those “public asset classes” has surpassed expectations by more than $2 billion, according to the comptroller’s analysis. But nearly all of that extra gain — about 97 percent — has been eaten up by management fees, leaving just $40 million for the retirees, it found."
Note "surpassed expectations" in there. That makes it sound not like the total return was $2B but that the return was $2B above projections, and after fees this was functionally erased leaving return at projected level. Am I misunderstanding the language here?
I don't fully agree with it — for one thing, I think you can develop taste in a field without actively participating, but you have to engage with it beyond passive consumption. Basically: I think it's possible to be a good movie critic without making movies yourself. Given the collapse of the friction/effort side of things, I think that is really worth unpacking.
I have to say I find the debates about the post's style and em dashes pretty disheartening. There have always been plenty of good jokes to be made about HN's culture, but wow. For a community that has been snarky about fools counting lines of code for 40 years to be out here counting em dashes is pretty damning.
