I think you're misinterpreting what "the implicit constraint 'b: 'a has been lost" in that link means. What it means is that the compiler loses track of the constraint. It doesn't mean that the language semanti

Yes. I'm not saying that Miri demonstrates anything other than that it's not a language issue.
333.
by pcwalton 3y ago
But it's not a fundamental design flaw in the language, nor is it a "hole in the type theory". It's a compiler bug. The compiler isn't checking function contravariance properly. Miri catches the problem, while rustc

This is exaggerated re. C, but it is true that the important thing for practical security is whether memory safety is violated in practice, and obscure compiler bugs you have to go out of your way to try to exploit don't affect that.

This is basically the Rust equivalent of the obfuscated C code contest and indicates little to nothing about the actual Rust people write.

The difficult parts change all the time and usually boil down to some sort of undocumented or poorly-documented dependency, especially if you're trying to enable the GPU backends. Every time someone I know tries to get it building it t

Our joke was "the recommended way to build Skia is to become a Google employee, but there are workarounds available if for some reason that isn't practical". There's also the question of "which parts of Skia".

Personally, I feel the real competition is the OSS Rust engines against Unity, Unreal, and to some extent Godot, rather than the competition being between Rust engines. Bevy and Fyrox are both great frameworks.

Bevy has actually moved away from the ECS for performance-critical lookups in the renderer where the ECS doesn't carry its weight. The engine isn't dogmatic about ECS use.

by pcwalton 3y ago
The term is kinda fuzzy and means different things in different engines, but in Bevy it refers to lightweight 3D wireframe overlays that you can use for visual debugging.

Here are the plans for the editor prototypes: https://github.com/bevyengine/bevy_editor_prototypes/discuss... As far as Lumen goes, there are a few experimental early-stage projects that add real-time global illum

I wrote the lightmaps, reflection probes, and irradiance volumes support for this release! Bevy has really been a joy to work with, and the community is fantastic.

Brave continues to ship Manifest v2. Technically Brave is a fork of Chromium for this reason, albeit one that hews close to upstream. The reason why Brave had to fork Chromium is that, again, Google completely controls Chromium's devel

by pcwalton 3y ago
Why does mobile Chromium still not have extensions? Why was Manifest v3 pushed so heavily? It's not for lack of resources: those are deliberate decisions made for business reasons. Brave pushed back as hard as possible against Manifest

It'd certainly be convenient if it were true, but the rate of Firefox's market share decline was completely unaffected by the switch to Web Extensions. There are Firefox forks out there that still keep the legacy add-on interface

Because Google completely controls its development.

Yeah, it seems to me like the author just wants a simple HTTP client for Rust that prioritizes simplicity over raw performance and is unhappy with the fact that reqwest isn't that. Though as developers we often wish it were otherwise,

I really want the switchto patch for high performance userspace threading. It'd potentially allow 1:1 threading to better compete with M:N, which would be very nice for systems languages like C++ and Rust.

> Note that Rust doesn't fix this problem. Rust just encodes the assumption of pre-known lifetimes much more strongly in the language. If you're not in such a domain then you have to fall back to refcounting, which is (a) slow

Fascinating, thank you! (I completely forgot I wrote that and also I'm mildly embarrassed at how I used to write back then.) :)

For Go I'd say there's a single synchronous runtime built-in. People say that Go is async because the implementation of goroutines is async internally, but the implementation of threads on every OS is async internally too. The o

Nowhere did the parent comment say either of those things. The guidelines tell you to assume good faith.

Bad idea re. Texas. UT Austin is extremely difficult to get into nowadays.

I'm happy with it. It's a nice improvement over HLSL/GLSL in Bevy.
359.
by pcwalton 3y ago
Note that WGSL is closer to Rust than C++--syntactically speaking anyway--and it's pretty much guaranteed to get traction as it'll be the only way to talk to the GPU using a modern API on the Web.
