> The Hadamard product is not geometrically meaningful! As of `d0975` there is no longer a `*` defined for vectors. `hadamard(v1, v2)` does what that operator used to do and a version of that for matrices already existed. The definition of a Rotor is identical to a geometric product (scalar+biv

Sugar.Collect macro inside a Sequence causing error

Hello, so i was recently trying to use sugar's collect macro inside a sequence, like this: import tables, sugar, sequtils, strutils let l = @[ {"one":1, "two":2, "three":3}.toTable, collect(newOrderedTable, ( for (i, j) in zip("sun mon tue wed".spl

Use SciKit-learn for machine learning from Nim? (Andreas please read!)

Hi folks, including Andreas and the other language founders (I hope you read this post)! Since Nim can talk to C libraries, is there some easy way to have a Nim program use SciKit-learn? Let me see if I can describe how much growth in popularity this might create for Nim...facts: * Python w

why Hints comes yet even {.push hint[Name]: off.} is added?

Convert Python codes to Nim codes

Thanks very much, @PMunch! I've learnt a lot. But for the 2nd algo, in the Python slice g[i::j][:L] is to loop from index i to end with step j. Not i to j => g[i:j]. Python has this [start:end:step] slice. Hence, I don't know how to convert this in nim. #--

jnim documentation ?

I discover Nim last month and I'm coding for the last 4 weeks on nim and the language is really great !!I'm exploring some modules and now I'm stock with jnim. I'm trying to use jnim and understand how it's work. I downloaded the module to execute some tests but I get this error :

Read/write access to global variable in multithreaded application

For the errors issue it's just a matter of creating a nim.cfg file which sets `threads: on`. Creating this file tells the editor that you're using this option, and you don't have to use `--threads:on` while compiling.

Read/write access to global variable in multithreaded application

I've been trying to get multithreading to work with a shared variable, but for some reason can't make it work. I've tried multiple things, but the following code is the closest I got to what I'm trying to achieve. So I tried to define a global variable with allocShared0 of type `seq[string]`. T

Explain current state of multi-threading

I've heard that it's advised to use the new channels with ARC/ORC: . This should be at the top of the stdlib channels docs, in my opinion.

C function dependencies in os:any

You could look through this repo for a bare metal example: Nim doesn’t really require too much, or generally require string.h or similar. The main thing to worry about is memory allocation. See the Nim Compiler docs for setting that up:

Explain current state of multi-threading

Explain the situation with multi-threading, now it seems to me a little confusing. With GC: refc heaps are local for each thread. Therefore, it is only possible to copy shared data, or manual control via ptr (which is unsafe). With GC: ARC/ORC heap is shared so data can be moved. ARC doesnt use
