nim-stint VS go

> I think the message is more nuanced

I thought it was more nuanced too as they were explaining how integer types can be derived, until I finished the article, and they really did just seem to be complaining that there's a mismatch between compile time and run time.

Dynamic types don't really solve the problems they mention as far as I can tell either (perhaps I am misunderstanding), they just don't provide any guarantees at all and so "work" in the loosest sense.

That's a good point, I do wonder why they didn't mention Lisp at all.

What they want to do can, as far as I can see, be implemented in Nim easily in a standard, imperative form, without any declarative shenanigans. Indeed, it is implemented here: https://github.com/nim-lang/Nim/blob/ce44cf03cc4a78741c423b2...

Of course, that implementation is more complex than the one in the article because it handles a lot more.

At the end of the day, it's really a capability mismatch at the language level and the author even states this:

> Programming languages ought to be rethought.

I'd argue that Nim has been 'rethought' specifically to address the issues they mention. The language was built with extension in mind, and whilst the author states that macros are a bad thing, I get the impression this is because most languages implement them as tacked on substitution mechanisms (Rust/D), and/or are declarative rather than "simple" imperative processes. IMHO, most people want to write general code for compile time work (like Zig), not learn a new sub-language. The author states this as well.

Nim has a VM for running the language at compile time so you can do whatever you want, including the recursive type decomposition (for example: https://github.com/status-im/nim-stint). It also has 'real' macros that aren't substitutions but work on the core AST directly, can inspect types at compile time, and is a system language but also high level. It seems to solve their problems, but of course, they simply might not have used or even heard of it.

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.

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

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.

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.

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.

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!
