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.

Lag Is Never Where You Want It... Or Don't Want It
Reading ebiten docs and source code they very clearly state that writing RGBA bytes to an image is slow, and shouldn't really be done every frame, at least many times per frame. This is where I thought my performance was being lost, and it sent me looking for answers for ages. Turns out, I was wrong and right.

Making Games in Go for Absolute Beginners
I love Go, yet I've never thought of it as a language with usable game engines. I'm extremely happy to find I was very wrong about that!
I'm woefully behind the curve on compiling to WASM, though, and I've yet to experiment much with tinygo so I have no idea how far I would get in creating a game people could enjoy in a browser without having to download a big bundle of assets. It's reassuring to see WASM mentioned explicitly as a compilation target [1] by Ebitengine though.

Is there a love2d for c++?
What about learning Go with Ebiten? Or Rust with Bevy?

What would be the closest thing to Unity/Unreal C#/C++ for Go to create games/animations/visual work?
Actually, there is a game engine in Go. Ebiten(gine) is actually really popular and has already been used for a few games in production

Mac + opengl
I noticed a similar issue when I got my MBP with the framebuffer not matching the window size and this has to do with the DPI settings. This GitHub link helped me understand the issue better and I hope it can be of assistance to you https://github.com/hajimehoshi/ebiten/pull/1811

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

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!
