Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Bevy XPBD: A physics engine for the Bevy game engine
There is now also https://github.com/jrouwe/JoltPhysics which is used in Horizon Forbidden West.
-
Has anyone used Jolt physics engine?
Apparenty, this is a game engine used by Horizon Forbidden West and I was curious what you all think about this project: https://github.com/jrouwe/JoltPhysics
- After months of work, I'm excited to share the first release of Godot Jolt, an extension that integrates the Jolt physics engine into Godot, demonstrated using GDQuest's RoboBlast

Rust – Are We Game Yet?
As far as physics engines go: Jolt currently seems to kinda disrupt the decade-long equilibrium, at least as far as I'm aware:

X4's Upcoming Multiplayer Features Are a Huge Step Forward
No, they replaced Bullet with Jolt. That is considerably more than "some adjustment", regardless of what you think of the result.

Oof. 7fps for an incredibly simple rocket that is well under 100 parts.

Godot for AA/AAA game development – What's missing?
Would you rather they use Jolt Physics? https://github.com/jrouwe/JoltPhysics S&box is thinking of using this engine instead of Source 2's Rubicon. As they say, maybe someone could / would hook up Jolt as a GDExtension.
- Where and how can I learn to make simulation programs? I like to be a simulation developer!

Adding runtime benchmarks to the Rust compiler benchmark suite
> what do people use to run benchmarks on CI?
Typically, you purchase/rent a server that does nothing but sequentially run queued benchmarks (and the size/performance of this server doesn't really matter, as long as the performance is consistent), then sends the report somewhere for hosting and processing. Of course, this could be triggered by something running in CI, and the CI job could wait for the results, if benchmarking is an important part of your workflow.
But CI and benchmarks really shouldn't be run on the same host.
> What does the rust project use?
It's not clear exactly where the Rust benchmark "perf-runner" is hosted, but here are the specifications of the machine at least: https://github.com/rust-lang/rustc-perf/blob/414230abc695bd7...
> What do other projects use?
Essentially what I described above, a dedicated machine that runs benchmarks. The Rust project seems to do it via GitHub comments (as I understand https://github.com/rust-lang/rustc-perf/tree/master/collecto...), others have API servers that respond to HTTP requests done from CI/chat, others have remote GUIs that triggers the runs. I don't think there is a single solution that everyone/most are using.

Ask HN: Was programming more interesting when memory usage was a concern?
A lot of effort is spent to reduce the size of structs in the Rust compiler
https://nnethercote.github.io/2023/03/24/how-to-speed-up-the...
3% and 6% of improvement doesn't seem like much, but at the level of rustc those big wins
Performance of Rustc must be continously tracked (here https://perf.rust-lang.org/) because if you don't proactively fight against bloat, the tendency is that the code will become slower over time (due to new features etc)
-
Can Rust's compile time match its runtime performance?
hmm really really hard to answer :'), it's tradeoffs I think, no matter what you think Rust (cmiiw, I'm not qualified to say this) has (and probably in the future will adds more with guards on compiler metrics https://perf.rust-lang.org/) several phases that given the diffs to other language, might not available to any language compiler out there, if it's available I think rustc already did their best in here (some already being parallized etc etc, might be wrong since I can't refs any reference MRs, but it does exists though labels regarding this)

How to catch performance regressions in Rust
About a year ago I was looking for a tool like Rust perf for my application code. I did some research and found a lot of prior art. However, nothing checked all the boxes I was looking for, so I built Bencher!

Next Rust Compiler
https://www.pingcap.com/blog/rust-compilation-model-calamity... is a good overview. In general it varies depending on the crate but we track the performance at https://perf.rust-lang.org/ - if you look at cargo, for example, over 60% of the time is spent in codegen through LLVM: https://perf.rust-lang.org/detailed-query.html?commit=222d1f...
