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.

Reasons to Prefer Blake3 over Sha256
> might be easier with a public domain license instead of the current ones
There reference implementation is public domain (CC0) or at your choice Apache 2.0

Google abandons work to move Assistant smart speakers to Fuchsia
Fyi, blake3 was released in 2019 and should probably be used over blake2 unless you have some strong reason not to. It's basically a reimplementation of blake2 with performance tweaks.

Six times faster than C
Many people will argue that today's compilers are so smart/optimized that you'd be a fool to try to outsmart the compiler with asm. I'm not 1 of them, but I know some. IMO it's all a bunch of bullshit, there's a goddamn reason all the cryptocurrency mining CPU/GPU code is all hand-written asm. there's a reason blake3 is written in asm ( https://github.com/BLAKE3-team/BLAKE3/blob/master/c/blake3_sse41_x86-64_windows_msvc.asm ) - but the thing is, 99.99% of the time, life is too short to outsmart the compiler (unless you're Alexander Yee)

[QUESTION] Low speeds when creating blake3 checksum?
I have been trying to optimize my code to create a fast hashing function to create and check b3 file integrity but b3sum is way way faster than my aproach, i have been trying to modify my code acordingly to https://github.com/BLAKE3-team/BLAKE3/blob/master/b3sum/src/main.rs with no luck, so if anyone can give me some tips/clues on how to achieve better speeds it would be incredible. Thx!!

A good hash function for DEFLATE?
BLAKE3 might be faster than KangarooTwelve and is also an XOF. It doesn't have the benefit of getting a working RFC draft proposal however.
-
PoxHash, a bespoke denovo hashing algorithm implemented dep-free in Rust and 5 other languages. Rust compiled with rustc with -O is faster than GCC-compiled C with -O3!
You're saying the hash speed is 133 kB/s? That's extremely slow, for example BLAKE3 achieves 6.8 GB/s which is over 50000 times faster. Nobody wants to use such a slow hash function.

What's everyone working on this week (4/2023)?
Try this one if you want a smaller, and particularly interesting crate: https://github.com/BLAKE3-team/BLAKE3

New Ryzens and Chia plotters
blake3 is a cryptographic hashing function, which is used during plotting's "forward propagation" step
-
Image displays its own MD5 hash
BLAKE3 claims to be faster and more secure than both MD5 and SHA1.

The Linux Kernel Prepares for Rust 1.77 Upgrade
This is a good guide on building small Rust binaries: https://github.com/johnthagen/min-sized-rust
This talks about going to extreme lengths on making the smallest Rust binary possible, 400 bytes when it was written, https://darkcoding.net/software/a-very-small-rust-binary-ind...
The thing is, you lose a lot of nice features when you do this, like panic unwinding, debug symbols, stdlib… for kernel and some embedded development it’s definitely important, but for most use cases, does it matter?

Rust wont save us, but its ideas will
Oh it was 137, haha. I will link you to this older comment of mine: https://news.ycombinator.com/item?id=29408906

Making Rust binaries smaller by default
Are you sure? If so then this is awesome news, but I'm a bit confused; the commit in that min-sized-rust repo adding `build-std` to the README was merged in August 2021: https://github.com/johnthagen/min-sized-rust/pull/30
Are you saying that at that point the feature still hadn't "landed in Rust nightly" until recently? If so then what's the difference between a feature just being available in Rust nightly, vs having "landed"?

Was Rust Worth It?
Rust binaries are by default nowhere close to 500MB. If they are not small enough for you, you can try https://github.com/johnthagen/min-sized-rust. By avoiding the formatting machinery and using `panic_immediate_abort` you can get about the size of C binaries.

Tiny Binaries (2021)
That must be without stripping. Also there are ways to reduce binary size. See e.g. [min-sized-rust](https://github.com/johnthagen/min-sized-rust). I've gotten stripped binaries of small cli utils less than 400KiB without doing anything special, less than 150 KiB by customizing profile settings and compressing with upx, and less than 30 KiB by replacing the std with the libc as the link shows. Haven't tried with fltk though...
