If a language allows you: - to map cleanly with what compilers know to optimize best - fine control over stack and heap allocation - has intrinsics / assembly escape hatch - allows you to specify that pointers don't alias (restric

AFAIK that was what Facebook tried with their modified BSD that granted patents unless you sued Facebook. Though that doesn't help against NPE.

I'm from Status, Nim's main sponsor and a blockchain company that is doing Ethereum 2.0 research and implementation in Nim. Nim had the following appeal for us: - Ethereum research is done in Python, we actually started our code w

JVM, CLR, Python bytecode or Lua JIT code are ultimately all transformed into machine code but those are not as fast as assembler. Being as fast as C is not about using C as an intermediate language but having data structures and control fl

That's what the Nim compiler does. Bigger than 3 words, pass-by-ref, otherwise pass-by-value. So the only important modifier is whether the parameter is mutable or not. Obviously if mutable it's always passed-by-reference.

As an European, I'm always surprised when someone says that our governments are efficient. We're always complaining about them.

I was always under the impression that Azure had a lead in ML-as-a-service. I really liked LUIS (Language Understanding Intelligent Service) back in 2017 and AFAIK only Alibaba had an offering similar to Azure at the time for ML-as-a-servic

When you need efficient parallel map or reduction you often go back to low-level C loops wrapped in a pretty map/reduce/array package like numpy or R. I'd argue that Einstein Summation like `C[i, j] = A[i, k] * B[k, j]` is mu

Golang didn't exist in the 90's though. Rewriting decades of core business logic would be a tremendous effort and amount of risk.

Julia and Nim don't have curly braces. Nim isn't object oriented either, it's procedural oriented just like C. Experienced Nim devs avoid methods and inheritance and only use them after very careful considerations. Mutation i

Without types everything is a pointer (boxing), and when you actually need the value you need to resolve (dereference). This is almost always cache miss. If the collection is polymorphic it's even worse because you dereference to acces

In ML you really want to use Numpy ndarrays, Pandas dataframes or Tensors. A list is much too slow because: - Not contiguous - No SIMD vectorization - No parallel processing Lists are mostly used for list of containers (for example storing

Personally, I use Nim to develop domain specific language for VM, JIT, emulators and neural networks. I'm currently writing a compiler for deep learning with both AOT (emitting Nim code) and hopefully later JIT (emitting LLVM IR) capab
