I found your post as it is the top hit on Blueksy for "Geometric Algebra" right now.
Do you have any favorite resources to recommend that helped you learn?

I don't think there's any reason to expect the "return of democracy" given that non-democratic entities like Apple continue to be the most rewarded despite what you've gone over. Apple and Tim Cook are doing fantastically given the system we've put in place for them, where our problems don't matter.

It seems to me that your `Catching` protocol is better-represented as a union type. Thoughts?

I'm all for the minimalism. I've always tried to start with minimal noise, minimal frequency rolloff pickups, and shape from there. And I stopped using real amps 20 years ago.
Have you tried www.youtube.com/watch?v=HYX7... or a competitor yet? Pickup modeling is still relatively new. I'm intrigued.

Do you have Fluence pickups in anything else yet? I wouldn't bother with an instrument without them at this point, but I also wouldn't get a non-multiscale instrument anymore either.
(I started playing ERGs and ERBs in about 2000, multiscale about 2010. Can't go back!)

Roll Player Adventures does use this arrangement, but only on multicolored (familiar 🐅) dice.
I still don't think I've seen this arrangement for 5:
⬜️⚫️⬜️
⚫️⚫️⚫️
⬜️⚫️⬜️
Using the negative space of 4, for 5, like this, might have helped 6 not be so unruly.
(Standard 5-quincunx is fine w/me in isolation.)

Don’t care. 😤😝
Both options are bad because standard 6- and 7-pip patterns don’t follow the precedent set by 2- and 3-.
Dice manufacturers should send out these replacements for all defective units:

The visuals to me are change for change’s sake. I’m ambivalent.
But the extra taps are indeed horrible. I don’t appreciate when design clearly doesn’t respect your time—especially when there’s a precedent where it had successfully been more respectful.

Because body is a ViewBuilder, the problem with view modifiers being View methods that return versions of `self`, is that, if you use them without leading dots, they are just more complex versions of this sort of infinite loop:
struct V: View {
var body: some View { self; self } // or just self
}
struct V: View {
var body: some View { self; self } // or just self
}

I.e. with two vectors, these are all the same:
normalize(normal1 + normal2)
normalize((normal1 + normal2) / 2)
normalize(mix(normal1, normal2, 0.5))
But it works with any number of normals!
normalize(normal1 + normal2)
normalize((normal1 + normal2) / 2)
normalize(mix(normal1, normal2, 0.5))
But it works with any number of normals!

Ah! That’s an optimization of “Nlerp”. 🥳
When you add vectors without dividing the sum by how many of them you’re adding, the result gets scaled by the vector count. But if you normalize afterwards, the length of the intermediate result doesn’t matter.

I can't tell how you're combining the normals there?
This article has the three obvious options, but I also had good enough results on early iPads just by adding two normals and subtracting 1. 😆

Your videos are amazing. The best in the business. But I can’t believe how fast you’ve been putting them out, and figured you would get burnt out at that pace. Please keep it going, but much slower. 😮💨

It's on our to-play list, but it's a sign of modern enshittification that it's on Apple Arcade, but unlike most Apple Arcade games, not on Apple TV. The Special Editions of the originals, which came out a decade and a half ago, were console releases, as they should have been.

There's a lot of mention of `===` in forums.swift.org/t/se-0261-id..., but it's not in the standard library.
The `===` we've always had doesn't require arguments of matching type, so I don't know that it would feel consistent. (github.com/swiftlang/sw...)
