This is also my experience. I'm not a DJ but I perform live electronic music using various MIDI controllers. If I quickly want to add or remove a sound, like a kick drum, to/from the mix, a slider is best. If I need fine control over a parameter, like a low-pass filter frequency, a rotary controller is usually better for the reasons you mentioned.
As alluded to in the article, rotary vs. linear seems to be a proxy for the circuit which actually influences the sound. I would think that anyone claiming "mixers with rotaries always sound better" does not fully understand how they work. There's a lot of those kind of claims in the music scene.
Each hair consisted of four segments. All segments were sorted, then drawn back to front. Each segment was drawn as an anti-aliased line (no hardware support for this back then, so I had to invent my own line renderer). So a hair could not be thicker than one pixel but that's a reasonable assumption at a certain distance. This made it reasonably fast given the hardware at the time.
I've been wanting to reimplement this using modern shaders, to see how fast it would be these days, but haven't gotten around to it yet.
Some larger retail stores in Germany ask you for your postcode during checkout, presumably to learn a bit about their customer base. I don't mind telling them mine, there are about 16K people with the same postcode. But I'm pretty sure I would not tell them if I was one of the two forest rangers in Reinhardswald. (And yes, I do pay cash whenever I can.)
It's funny how every TUI developer eventually stumbles over Unicode and then handling international characters and emojis correctly turns into its own project close to the same scope of (or even bigger than) the original TUI project. It happened to me on rivo/tview and through the resulting rivo/uniseg package, I learned that all other TUI library maintainers deal with the same issues. Finally, everyone invents their own unique solutions to the problem because character width is not standardized and terminals are messy, as noted in the article. OP simply supports Unicode 9 only (Unicode is at version 15.1 at the moment). Sooner or later, users will complain, however, that certain emojis or international characters are not rendered correctly. So I'm not sure that this is a great solution.
I tried the model the article links to and it was so refreshing not being denied answers to my questions. It even asked me at the end "Is this a thought experiment?", I replied with "yes", and it said "It's fun to think about these things, isn't it?"
It felt very much like hanging out with your friends, having a few drinks, and pondering big, crazy, or weird scenarios. Imagine your friend saying, "As your friend, I cannot provide you with this information." and completely ruining the night. That's not going to happen. Even my kids would ask me questions when they were younger: "Dad, how would you destroy earth?" It would be of no use to anybody to deny answering that question. And answering them does not mean they will ever attempt anything like that. There's a reason Randall Munroe's "What If?" blog became so popular.
Sure, there are dangers, as others are pointing out in this thread. But I'd rather see disclaimers ("this may be wrong information" or "do not attempt") than my own computer (or the services I pay for) straight out refusing my request.
If you would like to know more about what made the Albrecht brothers' stores so successful, you should read Dieter Brandes's book. It think the English version is this one:
