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.

Proptest strategies the hard way
Proptest is a Rust crate for property-based testing. Recently I wanted/needed to manually implement a proptest strategy for my own type, and I realized that there is not that much material on how to do it. So I wrote a post where I tried to describe what I learned. It's a bit niche, but I hope that someone at some point will find it useful.

How to express Contracts in Rust?
Yes exactly, you can also add to this fuzzing and property based testing.

The birth of a package manager [written in Rust :)]
proptest is great! It generates random input data according to some rules, and if the input fails it saves random seed into a file so that failing inputs are guaranteed to be tested on the subsequent runs (as well as new random inputs). It also doesn't immediately stop on fail but tries to find a minimal failing input first.

Hey Rustaceans! Got a question? Ask here (11/2023)!
The only other crate I could find is proptest, but it looks a lot more complicated, and I don't know if lets you skip the shrinking step as quickcheck does. I've been reading the book and going through the docs, but a quick answer would be appreciated.

Announcing Proptest 1.1.0
We just released proptest 1.1.0, a property-testing framework for Rust. Proptest has recently found new maintainers, and this marks the first new release of proptest in ~2 years.

Hey Rustaceans! Got a question? Ask here! (32/2022)!
Hi, I'm working on a fuzzer, that fuzzes APIs based on OpenAPI specification. I'd like to implement shrinking. It means that when an interesting input (for the API) is found, I'd like to create the smallest possible input that still causes the same behaviour of the API. I'd like to implement a payload generation via proptest, because it already has the shrinking ability. I'm having issues implementing the JSON object as a proptest strategy. Here is what I tried so far. I explained it in a detail in stackoverflow question but it did not reach many people. Thanks for your help!

Which Mutex to use in this case (independent tasks, partially under contention)
Third, if you're opting out of a compile-time safety guarantee in the name of performance, test heavily (high-coverage unit tests, property testing, fuzzing, differential fuzzing, etc.) and make use of tools like Loom and Miri's runtime data race detector for unsafe code, which can catch stuff that is beyond the scope of the compiler's guarantees.

NuShell - Ceci n'est pas une |
These are just three small examples of what this shell written in Rust allows. The features are many and many more, but I'll leave it up to you to discover and enjoy them; I'm currently playing around with it and it's giving me a lot of satisfaction and immediacy, now it has a fixed place among the tools I use when working! The project is Open Source, so if you want to contribute, I invite you, as always, to do so, I leave you the link to the repo here!

Fish shell 3.7.0: last release branch before the full Rust rewrite
Any thoughts on fish as compared to nushell [0]? It's similar to PowerShell in its philosophy and is also written in Rust.

jc: Converts the output of popular command-line tools to JSON
> In PowerShell, structured output is the default and it seems to work very well.
PowerShell goes a step beyond JSON, by supporting actual mutable objects. So instead of just passing through structured data, you effectively pass around opaque objects that allow you to go back to earlier pipeline stages, and invoke methods, if I understand correctly: https://learn.microsoft.com/en-us/powershell/module/microsof....
I'm rather fond of wrappers like jc and libxo, and experimental shells like https://www.nushell.sh/. These still focus on passing data, not objects with executable methods. On some level, I find this comfortable: Structured data still feels pretty Unix-like, if that makes sense? If I want actual objects, then it's probably time to fire up Python or Ruby.
Knowing when to switch from a shell script to a full-fledged programming language is important, even if your shell is basically awesome and has good programming features.

jq 1.7 Released
Yeah agreed, especially now that PowerShell is available cross-platform.
Nushell[1] also seems like a promising alternative, but I havenโt had a chance to play with it yet.

The Case for Nushell
I also discovered an existing discussion[1] related to this topic which includes a link[2] to a "helper to call nushell nuon/json/yaml commands from bash/fish/zsh" and a comment[3] that the current nushell dev focus is "on getting the experience inside nushell right and [we] probably won't be able to dedicate design time to get the interface of native Nu commands with an outside POSIX shell right and stable.".

I appreciate what projects like Nushell and Murex are trying to address, but having a saner scripting language and passing structured data in pipelines is not worth the drawbacks for me.
For one, Bash scripting is not so bad if you set some sane defaults and use ShellCheck. Sure, it has its quirks, but all languages do. Even so, the same golden rule applies: use a "real" programming language if your problem exceeds a certain level of complexity. This is relative and will depend on your discomfort threshold, but using the right tool for the job is always a good practice. No matter how good the shell language is, I would hesitate to write and maintain a complex project in it.
And for general QoL improvements with interactive use, Zsh is a fine shell, while still being POSIX compatible.

Simple PowerShell things allowing you to dig a bit deeper than usual
I found nushell (https://www.nushell.sh) to be an impressive replacement "bash" for Windows
In terms of philosophy, think "Powershell but actually intuitive" : Every data is structured but command names are what you expect them to be. I usually don't even need to look at the documentation.
I liked it so much that I also replaced my shell on Linux with it, so I have the same terminal experience across all OSes
