The two languages are polar opposites in this regard, Zig places the burden on the developer and makes it easy for them to produce memory safe software, whereas Rust places the burden on the compiler and makes it hard for developers to produce memory unsafe software.
The article even points this out. I personally think it’s very good to have these two languages for these separate use cases.The right tool for the job and all that.
Fluxer is open sourced under AGPL: https://github.com/fluxerapp/fluxer/blob/main/LICENSE
It is completely self-hostable: https://docs.fluxer.app/operator/get-started/
It is currently starting development on federation: https://fluxer.app/blog/mobile-clients-and-fluxer-v2#why-is-federation-taking-so-long
It is absolutely not just Discord 2. And while they do have a very aggressive monetization scheme (can’t set a banner with the free account) that’s just to cover the development and hosting costs and it should be easy to disable them as the app is open-source.
