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.

Announcing `compact_str` version 0.7! A small string optimization for Rust
I didn't use any inline asm, instead I wrote the simplest if statement possible, which I confirmed on x86_64, x86, and aarch64 compiles down to use the platform's supported conditional move instructions. If this changes in the future and there's a need to write inline asm, you can do so in a portable way, e.g. the cmov crate.

Shoot me straight.
There's also cpufeatures which might suit your use case better (depending on exactly how you want to do it).

Crate for AES256 - which one to choose? Questions about block cipher modes and AEAD too.
I have seen that RustCrypto also offers a create for securely zeroing memory with: zeroize
-
`kindly`: a simplistic (and hopefully educational) implementation of a set-user-ID-root program (think mini `sudo`) for Linux
The zeroing routine itself looks fine to me. You might want to compare your code with the (already mentioned) zeroize crate, which does something similar (or maybe identical?).

Maybe found a Y2k bug in the rust-crypto DER-encoding util?
To save a few clicks, this was found to be, indeed, a Y2K issue, and der v0.4.1 has just been released to fix it. Citing the comment added to the issue after the fact:
-
Incredibly fast UTF-8 validation
I opened a tracking issue for that.

Now that the long-awaited const generics (MVP) have come to stable in 1.51, what crates are going to gain the most from it?

simdutf: Unicode validation and transcoding at billions of characters per second
That's not enough to make it interesting. There's already a porting of it in rust (https://github.com/rusticstuff/simdutf8), and inclusion in the stdlib has already been discussed: the problem is that you can't use simd in all supported targets and conditional compilation/detection is also very tricky.

Making Rust Float Parsing Fast: libcore Edition
No, libcore uses simple branching code at the moment, see https://github.com/rust-lang/rust/issues/68455. The issue is still actively being worked on. Note, it's not a simple drop in, and there seem to be even faster algorithms. For now there is https://github.com/rusticstuff/simdutf8.

What's everyone working on this week (19/2021)?
I will work on simdutf8, either
- simdutf8 v0.1.2 - Apple Silicon can get very fast UTF-8 validation too
-
simdutf v0.1.1 - A small step for semver, one giant leap for performance.
Now I have to benchmark again, it might be negligable. See also the discussion for this pull request.

Show HN: High-speed UTF-8 validation in Rust
Check the benchmarks section (https://github.com/rusticstuff/simdutf8#Benchmarks), second table. simdutf8 is up to 28 % faster on my Comet Lake CPU. However with pure ASCII clang does something magical with simdjson and it beats my implementation by a lot. GCC-compiled simdjson is slower all around except for a few outliers with short byte sequences.
The algorithm is the one from simdjson, the main difference is that it uses an extra step in the beginning to align reads to the SIMD block size.
