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.

Backward compatible implementations of newer standards constructs?
For span I would recommend the guideline support library - gsl::span

Hey Rustaceans! Got a question? Ask here (20/2023)!
Not sure how things are at this point so you might want to look up with those keywords, but a few years back clang-tidy was one of the suggested tools, or enabling the core guidelines checker in visual studio if you're using that. Maybe using GSL or something similar as well.

Hardening C++ with Bjarne Stroustrup
When I want safety guarantees, I use the original and run-time checked gsl::span, rather than std::span. https://github.com/microsoft/GSL .

I love building a startup in Rust. I wouldn't pick it again.
Another solution: use std::span (or some alternative implementations if the codebase doesn't use C++20).

C++23 “Pandemic Edition” is complete
If you ask me, the GSL [1] alone is a fairly radical departure from C++ that delivers a lot of safety. I don't know if it's gotten much popularity, though. Probably because it introduces a similar disruption like you might find from a brand new programming language.

Using Rust at a startup: A cautionary tale
> With Rust, though, one needs to learn entirely new ideas — things like lifetimes, ownership, and the borrow checker. These are not familiar concepts to most people working in other common languages ... Some of those “new” ideas are, of course, present in other languages — especially functional ones.
With C++, lifetime and ownership are just about as important but unfortunately no one's got your back. You can ignore lifetimes and ownership but you do so at your own peril. And the compiler won't tell you you're doing it wrong because the language wasn't designed for it to do so.
If you want a taste of rust's "mindset" (with respect to limitations imposed by some types) without jumping ship to a new language, try C++'s Guidelines Support Library [1]. It introduces some of the same benefits/friction as switching to rust but without a new language. Opting-in to some of these guidelines might be a gentler way to get some of the benefits of Rust. But it comes with a similarly higher bar.

I created a memory leak using smart pointers
It's also far more verbose than T* or T& (probably intentionally). If you really want a non-nullable pointer, gsl::not_null from the GSL is a good option. Writing your own version is also trivial, if you don't want to add a dependency.

C++ exams to practice
I use unique_ptr, but not as much as I used to. I've never used shared_ptr. This is my library that uses some C++ 2020 and 2017 features.

What led you to use Linux as your daily driver?
I started with Linux in the late 90s. I switched to FreeBSD around 2013 and returned to Linux a couple of years ago. Io_uring was the main reason I had to come back. At first I ported the back tier of my code generator back to Linux and then I ported the middle tier from being POSIX based to Linux.

Simpletonian approach to services?
Are there others that minimize multithreading and opt for multi-processing with single threaded processes? Call me a simpleton, but this approach eliminates some of the most difficult bugs by design. Here's an example of one of my single-threaded servers. The network io is asynchronous, but the file io is synchronous. Thanks

Ask for info: Sample open source program offer command line interface handling

Version 1.15 of the C++ Middleware Writer
It's a merger of services and code generation: an on-line code generator that outputs low-level messaging and serialization code based on high-level input. It's implemented as a 3-tier system and uses output from the code generator in each tier. There's also a traditional library that's part of the repo.
Support for more data types for message lengths. Previously message lengths were always 4 bytes. I used this, for example, to reduce the size of the type used for message lengths between the front and middle tiers of the CMW from 4 bytes to 2 bytes.

More concretely, I use it to generate code that's used in each of the tiers mentioned above. The link is to one example of that.
