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.

What even is a JSON number?

Although it would be good to move in the direction of using a BigDecimal equivalent by default when ingesting unknown data.

Working with Numpy floats and Forex financial instruments
There's no such thing as precision for floats. Floating-point calculations are always inaccurate: read this: https://0.30000000000000004.com/

Decoding Why 0.6 + 0.3 = 0.8999999999999999 in JS and How to Solve?
In everyday math, we know adding 0.6 + 0.3 equals 0.9, right? But when we turn to computers it results in 0.8999999999999999. Surprisingly, this doesn’t just happen only in JavaScript; it’s the same in many programming languages like Python, Java, C too. Also, it’s not just about this specific calculation. There are many more decimal calculations showing similar not-quite-right answers.

64-Bit Bank Balances ‘Ought to Be Enough for Anybody’?
Surprisingly common values like 0.1 don't have a precise representation in binary for most formats, including standard floating point number formats. See https://0.30000000000000004.com/ for more detail than you can shake a stick at.
Also if the local tax code states using 5 decimal places for intermediate values when you will introduce “errors” using formats that give greater precision as well as those that give less precision. Having work on mortgage and pension calculations I can state that the (very) small errors seen at individual steps because of this can balloon significantly through repeated calculations.
Furthmore, the name floating point gives away the other issue. Floating point numbers are accurate to a given number of significant figures not decimal places. For large numbers any decimal places you have in the result are at best an estimate, and as above any rounding errors at each stage can compound into a much larger error by the end of a calculation.

Learning Rust: A clean start
My first port of call was to google learn rust which lead me to "the book". The book is a first steps guide written by the rust community for newbies (or Rustlings as they're called) to gain a 'solid grasp of the language'.

Prodzilla: From Zero to Prod with Rust and Shuttle
Before Prodzilla, I’d read 'The Book' a couple of times, and had made my way through Rustlings, but hadn’t yet built a serious project in Rust.

Help me stop hating rust
To answer your last question;
Start with the Rust book.
https://doc.rust-lang.org/book/
Then do Rustlings until the syntax becomes muscle memory.
Then join the Discord and start doing little projects.
You won’t get up to the proficiency of other languages as quickly in Rust. It takes longer. For me it’s taking a lot longer, but I enjoy it.

Top 10 Rusty Repositories for you to start your Open Source Journey
Before diving into these repositories, familiarize yourself with Rust and its development ecosystem. The official Rust book is an excellent resource for developers at all levels. Each repository has documentation on how to contribute, covering code style, issue tracking, and pull requests.

Command Line Rust is a great book
This is my third Rust book after the official book and Rust in Action. The other two books are great, but they were too theoretical for me. I'm a slow learner and had much trouble grokking Rust's features and idiosyncrasies. When I was done with these books, I was lost and unsure of what I could do.

Nim
It's the same reason everything digital and downloadable isn't free: there's a cost to create it and there's a value to it.
For a language developer to charge for a book about that language, I think that's a completely valid way to make some money off of their work.
Even the Rust book, "The Rust Programming Language" is available freely online [0], but also as a print and ebook for sale via NoStarchPress [1].

Ask HN: How do you learn Rust in 2023?
I am looking at The Book (https://doc.rust-lang.org/book/), but hoped there was an amazing person on youtube.
Yeah, I'll build something, finally trying webassembly.
