    The Go programming language

  • I guess it's become trendy to hate on Go in this forum, so I'll offer a counterpoint.

    Being a relative newcomer to the language, transitioning from Python circa 2016, I've found it a joy to use. The simplicity of the spec, the true "one way to do it" philosophy, the way it forces you to simplify and avoid cleverness (yes, sometimes at the expense of verbosity, which only makes things clearer, and rarely tedious), the great crossplatform support, stdlib, and tooling around it, and many more features, have made it my favorite language.

    Yes, there are still some warts and odd design decisions, but those are far outnumbered by the good things about it. Most of the issues are related to Go's team unwavering dedication to backwards compatibility, which is respectable. The fact we got generics in v1 is incredible. I can't wait for what v2 will bring, without the shackles of backwards compatibility.

    This errors feature in 1.20 is neat, but I'm much more excited for context cancellation reasons[1], which will hopefully be released soon as well. That should greatly simplify debugging, and avoid the common generic "context canceled" errors.

  • v-mode

    🌻 An Emacs major mode for the V programming language.

  • I think something like V is what you're looking for:

  • WorkOS

    The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.

  • dmd

    dmd D Programming Language compiler

  • Nim

    Nim is a statically typed compiled systems programming language. It combines successful concepts from mature languages like Python, Ada and Modula. Its design focuses on efficiency, expressiveness, and elegance (in that order of priority).

  • Nim [0] feels like it ticks a lot of those boxes. Although it has Options I do not think the machinery is as robust as Rust where that feels like a foundational core of the language.
