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.

When counting lines in Ruby randomly failed our deployments
I noted the bytecount Rust crate uses an SSE4.1 intrinsic in SSE2 code and submitted a fix

Interview Question: Select a Random Line from a File (in Rust)
The article also mentions u/logiq's bytecount. We didn't use, but we mention it as an extension that could make the program faster. - Carl

Learning SIMD by creating a char counter, but it's slower than `.chars().count()`?
What's going on here? At one point I even directly copy + pasted everything from https://github.com/llogiq/bytecount/blob/master/src/simd/x86_avx2.rs , but got similar results. `bytecount` wasn't compiled with SIMD enabled either, if it was it would be ~40 GiB/s.

What's everyone working on this week (23/2021)?
Also TWiR and perhaps some clippy work. And at some point I want to revisit bytecount to add ARM/NEON and WASM optimizations.

S p a m m y s y s C a l l s in strace dumps
Yeah, excellent description of why the volume is so high, and when you're tracing a multithreaded one there's the additional noise from the way they're interleaved.
Besides filtering, I forgot to mention that some kind of aggregation/summary. strace flags are useful; even better to write a little program with eBPF (on Linux) or DTrace (on macOS/BSD/Solaris). I like being able to do stuff like this: https://github.com/scottlamb/retina/issues/5#issue-933945792

Async cancellation: a case study of pub-sub in mini-redis
I suspected exactly that in this issue in one of my libraries, but when I actually looked with strace, I didn't see many syscalls returning EWOULDBLOCK. So then after that measurement, my new theory was that e.g. tokio::net::{Udp,Tcp}Socket would skip actually issuing the syscall if the mio layer hasn't returned availability since the last poll. Not true? Maybe I need to run my experiment again...

What's everyone working on this week (23/2021)?
I'm plugging my new RTSP library retina into moonfire-nvr. But progress may be slow this week due to family obligations.
What are some alternatives?
koto - A simple, expressive, embeddable programming language, made with Rust
neolink - An RTSP bridge to Reolink IP cameras
tiny-tokio-actor - A simple tiny actor library on top of Tokio
aboba - Yet another audio book player (mobile friendly)
gdbstub - An ergonomic, featureful, and easy-to-integrate implementation of the GDB Remote Serial Protocol in Rust (with no-compromises #![no_std] support)
artillery - Fire-forged cluster management & Distributed data protocol
moonfire-nvr - Moonfire NVR, a security camera network video recorder
ruby - the Ruby programming language, unofficial mirror (see the wiki for details)
quickwit - Quickwit is a fast and cost-efficient distributed search engine for large-scale, immutable data. [Moved to: https://github.com/quickwit-oss/quickwit]
