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.

Rust: Actix-web and Daily Logging
// To load RUST_LOG from .env file. dotenv().ok(); /* On Ubuntu 22.10, calling UtcOffset's offset methods causes IndeterminateOffset error!!

Getaddrinfo() on glibc calls getenv(), oh boy
The problem is that this effects higher languages too, because they often build on libc. And on some OSes, they don't have a choice, because the system call interface is unstable and/or undocumented).
For example in rust, multiple time libraries were found to be unsound if `std::env::set_env` was ever called from a multi-threaded program. See:
https://github.com/time-rs/time/issues/293 and https://github.com/chronotope/chrono/issues/499
- The time crate has officially adopted an N-2 MSRV policy for end-user improvements and an N-4 MSRV policy for internal improvements.

Simple, fast and safety alternative for unzip
On that note, it would also be good to configure cargo-deny so that a CI pipeline and any maintainer can easily audit the current dependency versions. Sometimes CVEs require a new major semver (looking at you, time 0.1.x and thus chrono 0.4.x), so it's not enough to rely on people installing the tool with semver-compatible updates. Automatically auditing dependencies is really important, and given how easy cargo-deny makes it, I don't think many projects have any excuse not to configure it.

Hifitime 3.5.0: time.rs and chrono alternative, only more precise, formally verified, and used in scientific and engineering programs
I've come to understand that correct support for leap seconds for time computations cannot be implemented in a reliable and globally consistent manner. Here is a GitHub discussion that touches on this.

What lightweight date/time library to use? [2022 edition]
I'm not fully aware of all the history but here's what I think happened: time 0.1 was originally a minimal wrapper around libc time functions, maintained by Alex Crichton. (I seem to remember it may have been part of the std library before 1.0, but I'm not sure about that part.) In August of 2016 it was declared to no longer be actively maintained, with the README stating bugs would still get fixed.

Show HN: Fancy-ANSI – Small JavaScript library for converting ANSI to HTML
Recently did something similar in Rust but for generating SVGs. We've adopted it for snapshot testing of cargo and rustc's output. Don't have a good PR handy for showing Github's rendering of changes in the SVG (text, side-by-side, swiping) but https://github.com/rust-lang/rust/pull/121877/files has newly added SVGs.
To see what is supported, see the screenshot in the docs: https://docs.rs/anstyle-svg/latest/anstyle_svg/

Learning Rust: Structuring Data with Structs
Another week, another dive into Rust. This time, we're delving into structs. Structs bear resemblance to interfaces in TypeScript, enabling the grouping of intricate data sets within an object, much like TypeScript/JavaScript. Rust also accommodates functions within these structs, offering a semblance of classes, albeit with distinctions. Let's delve into this topic.

Algorithms for Modern Hardware
There’s also other reasons. For example, take binary search:
* prefetch + cmov. These should be part of the STL but languages and compilers struggle to emit the cmov properly (Rust’s been broken for 6 years: https://github.com/rust-lang/rust/issues/53823). Prefetch is an interesting one because while you do optimize the binary search in a micro benchmark, you’re potentially putting extra pressure on the cache with “garbage” data which means it’s a greedy optimization that might hurt surrounding code. Probably should have separate implementations as binary search isn’t necessarily always in the hot path.
* Eytzinger layout has additional limitations that are often not discussed when pointing out “hey this is faster”. Adding elements is non-trivial since you first have to add + sort (as you would for binary search) and then rebuild a new parallel eytzinger layout from scratch (i.e. you’d have it be an index of pointers rather than the values themselves which adds memory overhead + indirection for the comparisons). You can’t find the “insertion” position for non-existent elements which means it can’t be used for std::lower_bound (i.e. if the element doesn’t exist, you just get None back instead of Err(position where it can be slotted in to maintain order).
Basically, optimizations can sometimes rely on changing the problem domain so that you can trade off features of the algorithm against the runtime. These kinds of algorithms can be a bad fit for a standard library which aims to be a toolbox of “good enough” algorithms and data structures for problems that appear very very frequently. Or they could be part of the standard library toolkit just under a different name but you also have to balance that against maintenance concerns.
