What makes the nim compiler slow

To give a bit of background, we've seen similar profiling results in applications we make, and fixing it comes down to two things: * avoid large stack allocations - these severely mess up the stack scanning * avoid allocating lots and lots of short-lived objects - this is a classic that GC l

What makes the nim compiler slow

1. Looking forward to that! Though this comment highlights a few important points - ie how writing code for ORC/ARC and normal GC is different meaning lots of code that's been optimized for the latter will have to change to make the transition, and how difficult it is to write general-purpose

Youtube "Software Drag Racing" to count primes in Nim

@cblake: > FWIW, time - microsec/pass, not rate - passes/5sec - is better to report... For sieve comparisons and similar to your preference in putting something related to time on top, I actually like "CPU clock cycles per culling/marking operation" as that then allows one to compare "base", "w

String formatting a number with Javascript backend

I've encountered an error when trying to use `strformat` with a number in the Javascript backend. It's not a show stopper as there is another way. But it is really bugging me that I don't understand why I am encountering a problem and I would prefer to use the `strformat` approach. If I have th

String formatting a number with Javascript backend

Use `string` instead of `cstring`, `strformat` can take `string`, only use `cstring` on the outer borders and if you really need it.

Getting Started with googleapi module

The video you posted uses python, which has google-made-API for its services. They maintain the API and support every feature they have. They have hundreds of programmers maintaining the python google api. While the googleapi module in Nim is made by me, and used by practically no one except me

String formatting a number with Javascript backend

Thank you for your reply! I'm still confused though. I can do this and `strformat` seems to have no issue with `cstring` import jsffi, strformat, jsconsole var obj = JsObject{field: "1".cstring} s = obj.field.to(cstring) var f = fmt"{s} is a string".cst
