Since we don't get much Shadertoy content here, I'll point out that, while this is really cool, there have been some much crazier fluid simulations on Shadertoy. The most insanely fast fluid sim I've seen there is the one by

My understanding is: Mosh can't scroll because it doesn't send you the full output of the terminal. It only sends you the current "window" (visible terminal contents) at the current time. ET sends you everything. So if a

Pretty cool, though it seems there are many common progressions that it can't make, as it forces you to choose a single scale for everything (the block titled "mode" should really say "scale"). For example, minor pr

Not the author, but I'll give my take on this. The Soundpipe library underlying Sporth is ideally suited to doing exactly what you describe. It exports all the required functions in a way that can be easily integrated with any extensib

That definitely looks cool. I remember looking at these when you mentioned them before, but then I got lost looking for example audio scripts. I just looked a bit harder and I think I found them: https://github.com/PaulBatch

I wouldn't read too much into it. " X is dead " is such a common sentiment on HN it's somewhere between funny and tiresome.

Thanks :D Since you're here, I would love to know what you think of adding function definition as a language feature to Sporth (in the style of Forth, or even better, Joy). As you know I've used Sporth a lot, and I think it would

If you're thinking of compiling this to webassembly and making an online Sporth playground... It's already done! Works pretty well, too. You can browse a bunch of Sporth scripts and play with them here: https://audiomas

If you want an simple algorithm to model this, waveguide synthesis can give surprisingly convincing results, including the difference between open and closed pipes. In short, a waveguide model involves delaying the signal (to simulate the s

Regarding the music synchronization, OK, this is ancient stuff. However, in terms of graphics, this strikes me as different from anything that was possible before the recent advances in GANs. During the era you're talking about, the ar

For some reason, I just made the connection to the flowers of Minas Morgul, whose description I always loved. Now I can confirm, there are definitely some mycotrophic plants on the foothills of Mordor: " Wide flats lay on either bank,

I remember seeing quite a bit of disturbing imagery when researching mycotrophic plants (which get nutrients from soil fungi and frequently don't have any cholrophyll). Maybe it's because they lack the usual green and leafy identi

You can still do pretty much the same thing. Win+D, Alt+F4.

Regarding the solidity of this technique, these days a lot of indoor climbing holds are made of fiberglass held together by epoxy, with a thin layer of textured plastic on the outside. These are generally called fiberglass volumes. The mate

I love this kind of information-packed article, especially on topics that usually yield fluff/opinion/anecdote pieces. The author seems to have written a lot of visionary-related texts and I'm curious to look at these.

That seems to be normal... I created a very similar platform (but text-based instead of graphical) and encountered the same problem. Despite the traffic, so far only 3 people shared anything on it: me, the guy who created the underlying lan

It's in that zone where the limit between native content and advertisement becomes blurry. Where do you draw the line where an advertorial [1] starts? Or native advertising [2]? This type of content is likely to become more common, too

It's not. Take this sentence: " ACE construction rules require that each noun be introduced by a determiner (a, every, no, some, at least 5, ...). " The sentence does not follow the rule it describes, since "rules"

There are still areas where you're very much "coding tight inner loops and wizardly algorithms", namely shader programming. But it's true this is only one component within the high speed rail network.

The section titled "Log-polar Mapping in 3D" is, as you say, simply adapting the same map to 3D. The section "Log-spherical Mapping" is about the proper 3D equivalent. However, while maps in 2D space can be neatly repres

The article mentions a lot of interesting properties of the complex exponential map. I find it especially neat that horizontal and vertical translation map to uniform scaling and rotation. A mapping that shuffles transformations around like

Interesting stuff, it appears to be their own data (I'm guessing aggregated from sources like the UN registry and observation). I was curious about the statistics on satellite missions so I put it into a table: Operational satellit

It's unlikely that the first self-replicating organism at the origin of life was a protein. As you point out, there are just too many moving parts that need to come together simultaneously. These days, I believe research is tending tow

They're saying that it's problematic because it's inconsistent. So that problem doesn't exist in Python.

There are other options. Controllers with knobs are often made for music, but can also be used effectively for stuff like 3D and image/video editing. A popular choice for editing photos is the Behringer X-Touch Mini. Also, you generall

Yeah, I'm not sure how the term applies here. If you're using Luna to make a program that generates output, "what you see" (the node graph) is definitely not "what you get" (the output). Maybe you can have an i

I don't really support it, but this exact method appears to be working pretty well for Ardour (and yes, they are using GPL 2). It has resulted in some awkward situations, such as Ardour being available in the package managers of some L
