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.

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
I've been working on this program for 13 years now. At one point it had 7 global variables and none of them were const. Now it has 4 global variables and 2 of them are const.

Would std::construct_at be better here?

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.

295 pages on Initialization in Modern C++, a new cool book!
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.

Go: the future encoding/json/v2 module
A Discussion about including this package in Go as encoding/json/v2 has been started on the Go Github project on 2023-10-05. Please provide your feedback there.

Evolving the Go Standard Library with math/rand/v2
I like the Principles section. Very measured and practical approach to releasing new stdlib packages. https://go.dev/blog/randv2#principles
The end of the post they mention that an encoding/json/v2 package is in the works: https://github.com/golang/go/discussions/63397

Microsoft Maintains Go Fork for FIPS 140-2 Support
There used to be the GO FIPS branch :
https://github.com/golang/go/tree/dev.boringcrypto/misc/bori...
But it looks dead.
And it looks like https://github.com/golang-fips/go as well.

Borgo is a statically typed language that compiles to Go
I'm not sure what exactly you mean by acknowledgement, but here are some counterexamples:
- A proposal for sum types by a Go team member: https://github.com/golang/go/issues/57644
- The community proposal with some comments from the Go team: https://github.com/golang/go/issues/19412
Here are some excerpts from the latest Go survey [1]:
- "The top responses in the closed-form were learning how to write Go effectively (15%) and the verbosity of error handling (13%)."
- "The most common response mentioned Go’s type system, and often asked specifically for enums, option types, or sum types in Go."
I think the problem is not the lack of will on the part of the Go team, but rather that these issues are not easy to fix in a way that fits the language and doesn't cause too many issues with backwards compatibility.

AWS Serverless Diversity: Multi-Language Strategies for Optimal Solutions
Now, I’m not going to use C++ again; I left that chapter years ago, and it’s not going to happen. C++ isn’t memory safe and easy to use and would require extended time for developers to adapt. Rust is the new kid on the block, but I’ve heard mixed opinions about its developer experience, and there aren’t many libraries around it yet. LLRD is too new for my taste, but **Go** caught my attention.

How to use Retrieval Augmented Generation (RAG) for Go applications
Generative AI development has been democratised, thanks to powerful Machine Learning models (specifically Large Language Models such as Claude, Meta's LLama 2, etc.) being exposed by managed platforms/services as API calls. This frees developers from the infrastructure concerns and lets them focus on the core business problems. This also means that developers are free to use the programming language best suited for their solution. Python has typically been the go-to language when it comes to AI/ML solutions, but there is more flexibility in this area. In this post you will see how to leverage the Go programming language to use Vector Databases and techniques such as Retrieval Augmented Generation (RAG) with langchaingo. If you are a Go developer who wants to how to build learn generative AI applications, you are in the right place!
