wireguard-go VS go

Would you accept https://github.com/WireGuard/wireguard-go/blob/master/tun/ne... as a solution? =)

Maybe https://github.com/cloudflare/boringtun or https://github.com/WireGuard/wireguard-go ?

It's likely just `tailscale serve https / `.

https://github.com/tailscale/tailscale/blob/main/ipn/serve.g...

And they also support direct embedding:

I think this is built on the wireguard-go + gvisor mashup, that allows you to do this with just Wireguard:

One of my favorite applications of this is this little tool that turns Wireguard VPNs into SOCKS5 proxies (which you can selectively enable in your browser)

https://pkg.go.dev/github.com/octeep/wireproxy

They added this pull-request to wireguard-go and i assume they have already included it in their new version.

Vanilla WireGuard doesn't provide a way to run a peer in userspace that can proxy traffic between another peer and an endpoint such as a web server because you need to be privileged to do thinks like work with raw packets. However, https://github.com/WireGuard/wireguard-go is a userspace implementation of WireGuard and has recently incorporated Google's userspace networking stack. This project uses these two userspace tools to "fake" a privileged WireGuard peer that proxies TCP, UDP, and (a small subset of) ICMP. It was written as a pentesting/red team utility for my team but it can also serve as a general makeshift VPN when you don't have privileges on a box you want to proxy through.

How "scratch" do you want to go from? Do you want to write your own virtual network driver, or do you want to use an existing driver like Wintun? Either way learning about Wintun would be a good start. Then there's the protocol, regardless of what language you learn, the wireguard-go implementation is a very good example of how to implement a secure protocol with modern language.

wireguard-go (the official userspace impl in golang) can do this since several months back. It uses gVisor's netstack as a tcp/udp provider to forward connections to its peer.

Here's a demonstration of both a http-client and a http-server running over wireguard (a poor man's QUIC): https://github.com/WireGuard/wireguard-go/tree/master/tun/ne...

fly.io wrote about such setups not long ago too: https://news.ycombinator.com/item?id=26315695

And tailscale.com uses a similar setup (with netstack) on non-Linux/xBSD platforms: https://news.ycombinator.com/item?id=28261683

I think you can try wireguard-go,

> The story begins in April 2019 with 89476f8cb5 in which David Crawshaw, aware of all these problems, created an IP type like:

It's in a PR here: https://github.com/WireGuard/wireguard-go/pull/11/files

Which mentions:

> Typically throughout WireGuard, we've used [4]byte for v4 and [16]byte for v6, considering the Go standard library's choice of v6-mapped-v4 to be a mistake.

It actually looks useful, there's something similar in wgtypes, and I wanted to use it recently [0] but that package unfortunately doesn't expose a way to write it out to a string/buffer, so I ended up almost replicating it.

(There's a lot of ways of presenting/parsing/constructing the same config options there! I'm sure if I were more fluent in Go there's some more succinct way.)

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!
