Regarding analytics, one option could be to replace Google analytics with [Plausible Analytics](https://plausible.io/) making stats public to see for everyone (so that you can see the stats on the blogpost you contributed to, for example). Plausible can be self hosted (it is open source) or use

What's the use case for a "block" statement?

blocks are also useful for some horrible things. for example: var x = acquire_hounds() block: defer: release_hounds(x) .. stuff go here .. Run this seems less interesting at first until you realize they can go in to templates or macros. which means yo

I know curl is a standard but in my experience dealing with millions of random URLs from Wikipedia , curl will fail on websites where wget succeeded. You'd think something as basic as retrieving a web page would would work equally well but they have different internal assumptions and I find wget

Math library for renderers and GUIs

The Hadamard product is not geometrically meaningful! While it's great for data processing, it doesn't really make sense to compute the Hadamard product of two _spatial vectors_ (i.e. two relative positions in space) The geometric product makes sense as a product, and so do the inner product and

What's the use case for a "block" statement?

A block act just like a lambda function (an anonymous proc ?) but with side effects ? One syntax caveat is the increase of the indentation level. With if, while, for statements and blocks in between, the code gets quickly too much indented. Your examples are great, but I am unsure about the sec

Math library for renderers and GUIs

I am very interested to learn how you use algebraic geometry here, I'll look into the linked articles before looking at your code, in a week or so. From a math POV, we do not have many names for element-wise operator, I do not know if there is a name for absolute value applied to each element of

Hmm, I didn't know about those, probably because they're only mentioned in the wiki and not on the homepage.

+1 for removing Google Analytics and implementing open alternatives to gravatar, recaptcha and anything else that's within reach. I have to stick up for the Nim IRC bridge. I'm on a few Discords with IRC bridges, and Nim's is by far the best, having decent support for edits, replies and code pa

Math library for renderers and GUIs

There's another issue of mathematical correctness. The `*` and `/` operators operate elementwise, which does not seem a geometrically meaningful operation. These _do_ have meaningful definitions in geometric algebra, but... There's a fundamental tension between linear algebra and geometric algeb

C function dependencies in os:any

Hi there. How can one find out exactly what C function definitions are expected to be present when compiling for a bare-metal or RTOS environment? For instance, I know that one probably has to provide a definition of `malloc` and `string.h` functions, but is there a definitive list of required f

Wave: illegal capture ' ' because 'weaveParallelForSection' has the calling convention:

Thank you for the comprehensive response ! I had wrongly assumed that the explicit capture is not needed because the code worked without it, if put outside proc. But since it didn't work with code in the proc, I should have thought something needs to be done different. The workflow here is simp

Why is db_postgres so slow?

PostgreSQL attempts to do a lot of its work in memory, and spread out writing to disk to minimize bottlenecks, but on an overloaded system with heavy writing, it's easily possible to see heavy reads and writes cause the whole system to slow as it catches up on the demands.

This was literally a lunch project, no ambitions so far to turn this into a real project. But bugs? Where are bugs? :)

Why is db_postgres so slow?

The bottleneck here is likely that db_postgres blocks. I would give @treeform's async library a try. On the other hand, even though Nim stdlib is 0.6% of the top Rust framework that's still nearly 4k QPS. If you want to help market Nim then look into optimising this, but if you want to just get
