HN discussionThe presence of a type system definitely improves maintainability, however it is only one of many factors. Being C and Haskell both statically typed, are they equally suitable for long term development? For example, Elixir is a more "strict" dynamic language than your usual Python/Ruby/Javascript. Data is immutable. There is no monkey patching. Most state changes happen explicitly via process communication. The macr…

HN discussionThis is my first year participating in AoC and I am going with Elixir. I think this will be a great experience as I can try solving the problem on my own and then watch Jose Valim's approach live on Twitch.

HN discussionThe Docker chapter does mention similar things, and José Valim recently wrote the following blog post on this: http://blog.plataformatec.com.br/2019/10/kubernetes-and-the-... In a nutshell, docker and k8s are to OTP what region failover is to k8s tech. They operate on different layers of abstraction and impact distinct components. OTP allows handling partial failures WITHIN an instance, something K8s can’t help with.

HN discussionHi, one of the authors here, the Docker chapter and soon to come Kubernetes chapter hopefully shed some light on this very question. They are not alternatives, docker and k8s complement Erlang. Jose Valim, creator of Elixir, also wrote about this recently http://blog.plataformatec.com.br/2019/10/kubernetes-and-the-... ?

HN discussionI'm working for a software consultant in Singapore. We tried Elixir for a few projects, and now we're still trying. So, I can share a few experiences from my view. - Elixir and the Phoenix framework is perfect when building concurrency systems.

HN discussionI agree with your frustrations but I don't think the blame is on "let it crash". As far as helping prevent bugs, let it crash won't help. It is not a replacement for a type system either. A type system for Elixir would definitely help you prevent bugs (but unfortunately implementing one is challenging). Let it crash is a mental model and a technique to handle bugs and avoid undefined behaviour when all other attempt…

HN discussionI am not sure I would say one is better than the other, but they are very different. As you said, in Rust you are forced to handle errors by the compiler. In Elixir, you actually don't. In fact, we even encourage you to [write assertive code ]( http://blog.plataformatec.com.br/2014/09/writing-assertive-c... ). This is also commonly referred as "let it crash". In a nutshell, if there is an unexpected scenario in your…

HN discussionWhat you describe sounds more like Orleans grains. Erlang's lightweight processes serve a different purpose than actors or objects, they're really about fault tolerance. A typical Phoenix app spawns one process for every HTTP request, websocket channel, or DB connection, for example. All these things have a lifetime shorter or equal to the pod's. The VM gives guarantees and tools to ensure one of these process crash…
