I know. I was eager to get this out. I'll be working on more visuals for a Libre Graphics Meeting presentation, where I'll include some of this in the Rust 2D graphics talk.

Patrick is of course right here, macOS isn't quite like Flutter because it basically always texturizes, although ultimately this is under control of the programmers. And perhaps it would be more …

Yes, macOS relies very heavily on CALayer to accomplish smooth scrolling, largely because much of the content of those layers is software-rendered. One thing that I find interesting is the subtle effe…

Yes. I'll have more to say soon, but I'm basically building what I think is next-gen UI infrastructure in Rust. That's a project with perhaps overly ambitious scope, so I'm starti…

What makes you say that 2D graphics has worked well? Scrolling often janks, UI designers constantly have to work around limitations in the imaging model and performance quirks (for a long time, clippi…

If you're talking about improving support for incremental present in Vulkan implementations, let's definitely connect. Certainly I can see how to do it well on Windows/DirectX, using ID…

It's complicated. 2D graphics aren't inherently harder or require more computation than 3D, but they require very different optimizations. I think it boils down to the fact that 2D graphics …

Yes, https://github.com/linebender/piet-metal , it's mac-only (for now).

Agree on both fronts! (Also, your username seems familiar somehow - have we had discussions around this before? :) I didn't talk about this in the post because I haven't actually implemented…

Agreed, and there are some deep issues, for example the rendering of very thin strokes which is quite dependent on resolution. Also keep in mind that the 4x4 oversampling you mentioned does not give n…

It is true that is more correct (see https://github.com/pcwalton/pathfinder/issues/142 ). But my motivation is much more user interface than document rendering, so it&#x…

These are all interesting questions. I've been following some of the stuff on Shadertoy, and I think that points the way. Most is 3d, but not all, and in particular there's a lot to be done …

Wow, this is good. I gave it "Configure your pipeline state object with a compute shader that consumes uniforms and vertex buffers." and it came up with this: Note that the compiler will add…

The other big problem with mmap is what happens when your file changes out from under you. This seems to be mostly for git packfiles, which I think can be treated as immutable by convention, but that&…

Try some JSON benchmarks with Codables in Swift vs serde in Rust. Rust smokes Swift, something like 20x. Incidentally I've spent considerable effort on this problem, including writing a prototype…

Yes, I've seen examples of calling Rust from Swift, and I do plan to support that. This particular thing is about calling macOS platform functions from Rust code. Projects either call Objective-C…

Maybe I can, I just haven't found an example of it. Certainly the "cc" crate doesn't seem to know how to compile Swift files. This might be more of a documentation issue than a rea…

I'm an extreme outlier, but I'm about to start an Objective-C codebase (a 2D renderer on top of Metal), because I suspect interop with Rust will be a lot easier. In particular, it looks like…

Flutter is implemented in layers. The RenderObject layer looks very much like a traditional retained mode UI. It's possible to write Flutter entirely at this level, nobody forces you to use the…

I'm not super-expert, but know of some background. I think Rosyln grew very much out of Delphi, and Anders Hejlsberg is the common thread to both. Before that, he did Turbo Pascal, which might ha…

You might wish for that, but the ship has sailed. Undefined behavior means that the implementation can do whatever it can. That said, I do expect tools, both sanitizers and static analyzers to improve…

From the article: > Dereferencing a nullptr gives a segfault (which is not a security issue, except in older kernels). I know a lot of people make that assumption, and compilers used to work that w…

The gold standard for redaction is to replace the redacted text with nonsense of similar length. Otherwise, you retain precise metrics for the redacted text. With guesses or context you can fill those…

This is true. The philanthropy scene is probably one of the few areas that has even more screwed-up incentives than academia.

This post resonated with me strongly. Yes, resigning sounds like the obvious best choice. I hope it works out well! I can certainly understand why Prof. Stein doesn't want to trash his colleagues…

In addition, it is entirely possible that when Rust has a formal semantics, it will use exactly such a provenance-aware memory object model to describe which pointer operations are safe and which lead…

Fair enough. cmix is awesome work, obviously, and I'm looking forward to the ideas becoming production-ready. Probably the most notable contribution by Fabrice Bellard is having something relativ…

I meant it as something of a joke (10x compression speed vs 10x the productivity of the average programmer), but also to summarize useful information from the paper.

And this is why Fabrice Bellard is so often cited as an example of a 10x programmer: his relatively simple LSTM-based neural net compressor is 10x faster than one of the more complex state of the art …
