   Reminds me of binarylang[0] (a library for binary parsing written in Nim). I used it in a small hobby project to parse ELF binaries in a declarative manner (well just the headers + string table)[1]. [0] https://github.com/se

   When I first started using Nim I was a snake_case person, and I was also put off by camelCase as the preferred style. Fast-forward a few years and I got used to the camelCase and moved on, focusing on what I want to build instead of persona

   Check out the discussion on my hobby kernel written in Nim: https://news.ycombinator.com/item?id=40962767 I tried to answer that question as best as I can after having implemented a few non trivial projects in Nim.

   I had to think hard about this, and I couldn't come up with something so obvious that it would be a no brainer to not use Nim. __MatrixMan__ and SJMG have good points. If it's anything, it wouldn't be a technical issue in the

   I went over this in other comments, but basically the language appeals to me since: - it's close to Python in syntax (less noise, more readable) - has no garbage collector by default (it uses ARC) - has great C interop - can be optimiz

   I did consider Swift for a brief moment, but was put off by the fact that targeting bare-metal was almost non-existent. It was more work than I would like to put into bootstrapping the dev environment.

    Fair enough. Keep in mind also that Nim is not backed by big tech, which is both a blessing and a curse. The community hasn't reached a critical mass yet to take Nim into the mainstream. All I can say is ... "be the change you wan

    To be honest, I haven't found the community size to be an issue. The Nim forum[0] has a vibrant community, and is the place I go to for help, and the response is usually quick and on point. The language is also evolving in a careful ma

    To be honest, I haven't found this to be an issue (yet). I try to keep most of my types value types (cannot be null), which the compiler can pass by reference under the hood if it detects that it's too big, without compromising me

    I haven't used nushell (although I'm aware of it). I'm aware that the idea of piping statically-typed objects between proceses is not new (PowerShell has had this since 2006). But the problem is that this is confined to the s

    Batching syscalls is on my mind. The architecture of Fusion will revolve around channel-based ipc (both sync and async), including between user mode and kernel mode. The end state I'm aiming for is an async channel for syscalls, where

    I haven't faced such issue. I think the only issue I faced was when I upgraded to 2.0, they made `--threads:on` the default, so I had to turn it off, but that's about it.

    A file is a manufactured concept that has served us well for a long while. But I'm not convinced that it's the right abstraction for everything. Files are just binary blobs (even if they're text), with no uniform interface to

    Thanks! Actually writing has helped me so many times in improving the design and implementation. It forces me to question my assumptions, and ask myself: would the reader be able to understand why I made such decision? I have to justify eve

    As others mentioned, Nim is a statically typed programming language that compiles down to C, C++, and JavaScript. It has great C interop, which makes systems programming easy. As for why Nim, here's an excerpt from my accompanying site

    Thanks! As @Tiberium mentioned, Nim 2.0 defaults to using ARC (Automatic Reference Counting), so no runtime GC. The Nim compiler is quite smart about when to copy/move and when to destruct, with some hints like lent/sink for when
