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.

You Don't Always Need Indexes
For ongoing monitoring of query performance, I use Percona Monitoring & Management - it's query log provides an easy way to spot frequent queries that may need optimizing.
-
Tuning ZFS for small read sizes - files use much more space than their size and high cpu use.
I cannot recommend PMM highly enough - it's free. You'll get a ton of insight into your DB's bottlenecks, and can use it to validate changes made.

How Database Indexes Affect MongoDB and Application Performance
I use the free, open-source tool Percona Monitoring and Management (PMM) for monitoring and graphing.

Idiomatic patterns you discovered in your work with Go
i don't know if this is an idiom or not but at my workplace each go repo has a separate tools/ directory, which only has 3 files `tools.go` , `go.mod` and `go.sum` https://github.com/percona/pmm/tree/main/tools

Running Databases on Kubernetes
Curious what monitoring solution you've used that's both plug-and-play and in IaC. And in any case, nothing stops you (I like this approach, actually) from running your monitoring solution in K8s. For DBs in particular, I'm a huge fan of PMM, which is a set of extremely thorough Grafana dashboards atop VictoriaMetrics, with some discovery tooling.

Recap Monthly Percona Developer Meetup Hacktoberfest
Our next project is Percona Monitoring and Management (PMM). This project is supported by Artem Gavrilov, Backend Software Engineer, and Nurlan Moldomurov, Full-Stack Engineer. PMM is a great project to contribute to during Hacktoberfest. There are minor and easy-to-do issues in Github; it is not necessary to register them in Jira. These contributions are welcome if you have any good ideas, want to improve something or simplify some process. Send your PR; the maintainers will review it as soon as possible. We also have advanced issues if you want to go for more advanced tasks.

Arena-Based Parsers
The description indicates it is not production ready, and is archived at the same time.
If you pull all stops in each respective language, C# will always end up winning at parsing text as it offers C structs, pointers, zero-cost interop, Rust-style struct generics, cross-platform SIMD API and simply has better compiler. You can win back some performance in Go by writing hot parts in Go's ASM dialect at much greater effort for a specific platform.
For example, Go has to resort to this https://github.com/golang/go/blob/4ed358b57efdad9ed710be7f4f... in order to efficiently scan memory, while in C# you write the following once and it compiles to all supported ISAs with their respective SIMD instructions for a given vector width: https://github.com/dotnet/runtime/blob/56e67a7aacb8a644cc6b8... (there is a lot of code because C# covers much wider range of scenarios and does not accept sacrificing performance in odd lengths and edge cases, which Go does).
Another example is computing CRC32: you have to write ASM for Go https://github.com/golang/go/blob/4ed358b57efdad9ed710be7f4f..., in C# you simply write standard vectorized routine once https://github.com/dotnet/runtime/blob/56e67a7aacb8a644cc6b8... (its codegen is competitive with hand-intrinsified C++ code).
There is a lot more of this. Performance and low-level primitives to achieve it have been an area of focus of .NET for a long time, so it is disheartening to see one tenth of effort in Go to receive so much spotlight.

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!
