Canonically the only reasonable solution and rpmbros should be made to compile the package themselves and be made to feel like they're on gentoo

To add to that: tbh text is AWFUL to render faultlore.com/blah/text-ha...
I'd be curious to see if there would be large differences in perf using something like sluglibrary.com, and offloading more work to the GPU. Does Compose use texture atlases to render text?

We do, but rarely to the granularity that gamedev has you do it. Lights have a 6ms budget, vertex skinning 1ms, etc, etc.
Also, this is still a platform that does (too much) work on the UI thread, we're affected by a lot of things outside of our control.

Could it be reached on a UI system like Compose with similar abilities? With the same constraints, yeah. But setting tech constraints like "can't have more than two layers of transparency/sampled textures" for general app dev just gets you open issues and complaints that "it's not good enough"

Yeah, Hypehype gets some impressively good looking results. But there's also different goals and targets: we generally speaking don't target a performance budget (aside from the very general 16ms), there's lots of alloc/dealloc and no arenas to improve the performance, instancing isn't done, etc.

I believe Unreal's Substrate is approaching that too ? (advances.realtimerendering.com/s2023/2023%2...) (PDF)
Takes into account medium, interfaces and microfacettes, layering, and goes all the way to path tracing compatibility. If not a perfect mathematical model, at least a damn good approximate

As always with fp math: here be dragons.
Other fun property of NaN: it spreads. Very fun if you're doing math on a large array and sampling neighbours. Ask anyone doing shaders how fun NaN propagation is to debug:D

Other "fun" fact about floating point numbers: their density goes down as the numbers goes higher. You're much more likely to not have inaccuracies doing, say, 0.672+0.867 rather than 12345.1 + 12345.2. you get ~800k numbers available between each power of two.

Hell, even just being able to use an arena or a custom allocator for memory allocation would be good.

At this point I almost feel guilty being involved in making you write multiple blog posts to explain gradle behaviours without even so much as a coffee given back.
Seriously though, thank you. Your blog is an incredible resource for anything Gradle related!

Hahaha, fair enough.
It just feels like a symptom of that is extremely common with some CI setups, and leads to situations where PyPI, maven central and others just bear an unneeded weight (www.sonatype.com/blog/maven-c...).

That something would be a lot easier to track down if getting a proper flamegraph was not an exercise in trying to understand which incantation I must give to gradle-profiler to measure just the configuration tbh

Or do the reverse, drop SwiftData (because it's at best a very average ORM in addition to being forever coupled to SwiftUI) and write SQL (using PureSQL, SQLDelight, whatever you want that just maps queries to nice to use functions in swift/kotlin). As a bonus, you'll stop persisting UI models to db

What do you think SwiftUI views do when they need to draw to a surface in the end, hopes and dreams? They delegate to UIKit, which uses CoreAnimation, then CoreGraphics
Skia is just a cross platform abstraction of drawing toolkits, it goes through CoreGraphics too.
Rendering isn't magic.
