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.

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!
- Rust – Are We Game Yet?

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...

Byte Magazine: The FORTH programming language
I hacked up a simple forth-like system in golang, by following the overview posted in this hackernews comment-chain:
https://news.ycombinator.com/item?id=13082825
The result is here:
https://github.com/skx/foth
It's not real, but it was a pretty fun experiment regardless.

Jonesforth – A sometimes minimal FORTH compiler and tutorial (2007)
Here's one of the many forks that brings it up to 64-bit:
https://github.com/matematikaadit/jombloforth
If you like forth there's an awesome series of comments here on hacker news on building a simple variant in a few simple steps:
https://news.ycombinator.com/item?id=13082825
I took that, and built a simple forth-like system, in golang following the original recipe and breaking it down into simple steps for learning-purposes:

ColorForth (2009)
I'll always vote up submissions referencing anything FORTH related. For me FORTH is as much fun as lisp appears to be for others. I've never really done much with it, but I always like the simplicity and the ability to reason about it.
Sure FORTH has problems of its own, but it's always nice to use. I've hacked up a couple of simple FORTH-like systems over the years, most recently this one which was inspired by a thread on this site:
https://github.com/skx/foth
A lot of people go through guides of writing a lisp, I'd love to urge people to try writing a simple FORTH interpreter instead, or even something somewhat related such as TCL.

Lang Jam: create a programming language in a weekend
There's even a recipe posted in a couple of comments here:
https://news.ycombinator.com/item?id=13082825
I followed that guide to implement a simple FORTH-like system in golang:
https://github.com/skx/foth
As I was following the implementation recipe I broke it down into "educational steps". Although it isn't a true FORTH it is pretty easy to understand and useful enough to embed inside other applications.
Now and again I consider doing it again, but using a real return-stack to remove the hardcoded control-flow words from the interpreter, but I never quite find the time.

Wisp: A light Lisp written in C++
I actually hacked up a simple forth-like system, after reading a brief howto here on hackernews:
https://github.com/skx/foth/
Here's the thread which has the barebones overview which inspired me:
https://news.ycombinator.com/item?id=13082825
I could have taken it further, but the implementation there is not "real" in the sense that there is no real return-stack, so you can't implement IF-statements using the lower-level primitives.
That said it is a good starting point, and I had some fun doing it. I'd guesstimate it is more of a single weekend project though, rather than longer.
