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.

Zig self hosted compiler is now capable of building itself
To clarify I meant as int8/int16's are packed in structs to compare to struct bitfields. Can't recall about the stack rules. Here's more discussion:
http://www.catb.org/esr/structure-packing/
https://github.com/Twon/Alignment/blob/master/docs/alignment...
Also ARM for example doesn't have 8/16 bit registers so int8 or int16 will use a 32bit register:

Curiosity got to me, perhaps Zig had improved significantly. So I compared the first benchmark I found (kostya/benchmarks/bf) with Zig with Nim. For the smaller input (bench.b) Zig did run with ~22% less RAM (about 20kB less).
However, for the larger input (mandel.b) Nim+ARC used ~33% less RAM in safe mode: Nim 2.163mb -d:release; Zig 2.884mb -O ReleaseSafe; Zig 2.687mb -O ReleaseFast. The Nim requires 0.5mb less ram and the code is ~40% shorter. I don't have time to try out the Rust or Go versions though.

From slow to SIMD: A Go optimization story
This is a task where Halide https://halide-lang.org/ could really shine! It disconnects logic from scheduling (unrolling, vectorizing, tiling, caching intermediates etc), so every step the author describes in the article is a tunable in halide. halide doesn't appear to have bindings for golang so calling C++ from go might be the only viable option.

Implementing Mario's Stack Blur 15 times in C++ (with tests and benchmarks)
Probably would have been much easier to do 15 times in https://halide-lang.org/
The idea behind Halide is that scheduling memory access patterns is critical to performance. But, access patterns being interwoven into arithmetic algorithms makes them difficult to modify separately.
So, in Halide you specify the arithmetic and the schedule separately so you can rapidly iterate on either.

Deepmind Alphadev: Faster sorting algorithms discovered using deep RL
It is not the sorting per-se which was improved here, but sorting (particularly short sequences) on modern CPUs with really the complexity being on the difficulty of predicting what will work quickly on these modern CPUs.
Doing an empirical algorithm search to find which algorithms fit well on modern CPUs/memory systems is pretty common, see e.g. FFTW, ATLAS, https://halide-lang.org/

Blog Post: Can You Trust a Compiler to Optimize Your Code?
It doesn’t apply in this case, but in general if you really want the best vectorization I would suggest using https://halide-lang.org instead of trying to coerce your compiler.
