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.

Blog Post: On Random Numbers
Defining an error type that is meaningful, portable, and compatible with no-std isn't straightforward. If the std lib's getrandom requires std, then just like that, rand and many other crates won't use it anyway. Using io::Result seems to me to face this challenge.

Hey Rustaceans! Got a question? Ask here (52/2022)!
Some wasm targets can’t generate random numbers at all but in the case of the book because you are using wasm in a browser you can use JS to generate random numbers. I believe there’s a way to get the rand crate to use JS as the backend for generating rand but its a bit more convoluted than the easy one-liner that the book suggests.

[Media] Nebulabrot rendered with Rust — Explanations in the comments
This uses rand and xcomplex to handle the mathematics, png to write image files, and dialoguer and indicatif for some pretty prompts and progress bars.

Do you ever use unsafe { .. } when not implementing custom data structures or interacting with external C code?
You can often achieve this without any unsafe by putting an assert!() on the length before the hot loop. For example, I got rid of some unsafe in rand that way.

Original source of `(seed * 9301 and 49297) % 233280` random algorithm?
This is a widely used method to map random integers to floating point numbers, but it has the disadvantage of wasting 1 bit of float mantissa precision.
On modern CPUs, its computational advantage over full-precision mapping methods, such as multiplication by a float, is not always clear [1].

Any plans for built-in support of Vec2/Vec3/Vec4 in Rust?
In fact, there are a lot of crates in Rust where in other programming languages, it would be included in the standard library. Examples are regex, random number generators, additional iterator methods, macros for other collections, num traits, loggers, HTTP libraries, error handling, async runtimes, serialization and deserialization, date and time, and many more.

Good example of high performance Rust project without unsafe code?
I'd like the mention my own refactoring of fast-float-rust to remove nearly all unsafe code for merging into Rust core library which left the performance identical to the previous implementation.

Making Rust Float Parsing Fast: libcore Edition
JSON is an interesting example, since the syntax of valid floats is slightly different than what Rust expects. Luckily, I'm the author of a minimal, and am also the author of a PR to bring this to fast-float-rust.
