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.

Semver violations are common, better tooling is the answer
yup, they reference it as an inspiration: https://github.com/rust-lang/crater
it's probably impossible to automate an entire ecosystem, and there is value to enabling a tighter integration within a project ecosystem (a subset of the language ecosystem).

Trip Summer ISO C++ standards meeting (Varna, Bulgaria)
Rather than hypothesising about an imagined tool you could look at the actual tool which of course is in Rust's source code repo: https://github.com/rust-lang/crater
> new proposed C++ changes - are checked against only easily and "well-known" accessible package.
Now that I have, so to say, shown you mine, lets see yours. Where is the tool to perform these checks in C++?
-
GCC 13 and the state of gccrs
The "break things" part of "move fast" is not essential, Rust cares so much about breakage they literally compile and run the tests for every crate on crates.io and github using a tool called Crater. They do this just to test changes, even for stuff thats documented to be unstable, because thats just courtesy. And tooling makes it trivial to switch between Rust versions.

Discussion about the state of neovim's plugin ecosystem
Rust compiler developers use a tool called Crater to test potentially breaking compiler changes on all crates (Rust's name for libraries) uploaded to the official repository. If plugin stability is the issue, maybe a solution along these lines would be better than merging these plugins to Neovim's core?
-
Experienced C++ users: what do you like about Rust? How would you sell it to other C++ users?
https://github.com/rust-lang/crater is the bot they use to test proposed compiler/stdlib changes against slices of the crates.io library up to and including "all of it".

Rust for Linux officially merged
I'm pretty certain this isn't actually true. You should look at the editions, etc. Rust also has an insane guarantee which I am certain C/C++ don't offer: It rebuilds its entire library ecosystem each time it ships to make sure nothing breaks (https://crater.rust-lang.org). I've never seen an instance were old code didn't compile on a new compiler. Rust isn't forwards compatible (new code compiles on an old compiler) of course, but what is?

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...
