   I've written several DSLs in Nim[1] for emulators & VM, JITs, parallel computing, neural networks and parallel tensor operations. [1]: https://nim-lang.org/

   Nim const are compile-time constants, it's completely different from C++ const. I don't agree on immutability, just like you have shallow copy and deep copy, you have shallow immutability and deep immutability. Also functional pro

   Actually plenty of issues are RFCs and feature requests. We have a new RFC repos to brings a bit more sanity to the bug tracker: https://github.com/nim-lang/RFCs/issues

   There are plenty of functional libs in the Nim ecosystem, the prominent ones being: * NimFP[1] * Zero-Functional[2] Disclaimer: my very first language was Haskell and I'm now a Nim core contributor. Mutability: just like Ocaml

   Hey library author here, you can ask me anything. I just released the 0.5 version of my multidimensional arrays (Numpy-like) + Deep Learning library (PyTorch-like) that I've written from scratch in Nim. Key highlights of this version:

   Oh fond times, I bought BG2 the day it was out and the early adopter CD with bonus. I also spent lots of time scripting the game, like trying to replicate Balthazar IA (the monk spawn of Bhaal that lead one of the last locations in Throne o

   I played with JITs in Nim recently I found it quite enjoyable. Here is my mandatory Brainfuck VM[1] and this is my opcode tables and probably what I like best about Nim metaprogramming[2] [1]: https://github.com/numforge&#x2

    The book is not really about algorithms, it talks about async, multithreading, with example on a building a chat app or a Wikipedia parser and a tweeter clone. So it's more web backend oriented for the practical stuff. Obviously it als

    You need to pass --gc:none when compiling so that the compiler warns you when you try to use a garbage collected type and instead of the stdlib, use the SDK facilities. Here are some libraries for embedded you can get inspiration from[1]: -

    I'm not sure Nim, Crystal, Rust, D (or C, C++) are that much better for searchability.

    That's bad naming, if those had the same type, that would lead to subtle hard to track bug because a dev used one pid instead of pId.

    Compile with `--threads:on` and everything in the threadpool module are available. You can also use `CreateThread` for long-lived threads. Alternatively, you have an open-mp for loop that you can use with `||`: for i in 0||1000:

    Very impressive, kudos. I'd like screenshots rather than PSNR and SSIM because those don't translate into human perception of a good encode. The only grip I have is the 13k lines of C + intrinsics.

    Compile-time function evaluation, superb metaprogramming and easy to write at a very low-level while you can enjoy the GC for non-perf critical parts. I use those daily in cryptography, VM/interpreter and bigint libraries development a

    By removing the C standard lib and using a custom linker you can get the Hello World down to 150 bytes. Here is a fun read: https://hookrace.net/blog/nim-binary-size/ .

    What algebraic datatypes is Nim missing? It has generics, tuples, tagged and untagged unions, it even has C++20 concepts.

    I use Nim for Cuda, OpenCL and cache-sensitive/memory-bound multithreaded computation. You can mix and match manual memory management and GC-managed types in the same codebase.
