go-sqlite3 VS go

Yep, I just made it tweakable at build, which was always the intent, although I expect the default to be popular.

That's unfortunate about the default parameters, but note that you can also replace the KDF altogether (besides just not using it).

You just need to implement this interface, with any HBSH construction and KDF:

https://github.com/ncruces/go-sqlite3/blob/67d859a5/vfs/adia...

If you keep the HBSH and change the KDF, your file format will be “compatible.”

struggling figuring out how to make my cgo sqlite cross-compile to Windows

Plenty of people trying to fix that.

There's at least:

https://modernc.org/sqlite

Then there's https://github.com/zombiezen/go-sqlite that actually builds https://crawshaw.io/sqlite on top of modernc.

And there's mine that has both a low level and a database/sql driver builds and runs everywhere Go does: https://github.com/ncruces/go-sqlite3

If you're interested both SQLite's and my memdb VFSes implement safe locking.

Depending on your familiarity with Go, mine maybe easier to follow, or not.

One thing I tried to make sure, to avoid the pitfall modernc is having, is to make sure building "the WASM BLOB" is easily reproducible with widely available tools:

https://github.com/ncruces/go-sqlite3/blob/main/.github/work...

I do apply some light patches to SQLite, but so far they've always cleanly applied, and I can produce a new release within hours of being notified of SQLite releases.

Disclosure: I'm working on alternative Cgo-less bindings for SQLite, using wazero.

One of the problems of the modernc approach (IMO) is that they're not just transpiring CPU/compute stuff, but entirely OS/platform stuff.

Each Go file of theirs is a xxx_os_arch.go that starts with 100s of OS-#defines-as-consts, and goes on to transpile fully #ifdefed code.

It also implements antithetical (in Go) stuff like goroutine local storage, because libc pthreads can't live without it.

And all IO is via direct syscalls that will never play nice with the Go scheduler, because, again this is OS level stuff.

WASM defines a cross platform CPU and an ABI, and using that for compute and the bottom OS layer in Go you get (IMO) a nicer end result.

Given the hard task of generating decent code from WASM at load time (wazero's compiler is pretty naive, a better one is being developed, but it will take seconds to generate good code for anything non trivial like SQLite) I wouldn't mind having a solution that translated to Go, or Go ASM, at build time.

The github.com/ncruces/go-sqlite3 is a link.

Using the stack pointer global is an interesting hack. I'd never thought of that. Need to compare with what I'm doing for SQLite (a kind of per connection arena).

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.

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!
