pixie VS Django

We have written pixie: https://github.com/treeform/pixie . Pixie is a 2D graphics library similar to Cairo and Skia written entirely in Nim. Which I think is a big accomplishment. It even has python bindings: https://pypi.org/project/pixie-python/

I made it because I really like pixie/boxy/windy combo, but there is no gamepad support built-in.

With Nim, you can continuously optimize and improve the hot spots in your code. For example, in the Pixie graphics library, path filling started with floating point code, switched to floating point SIMD, then to 16-bit integer SIMD. Finally, this SIMD was written for both x86 and ARM.

The author Fidget actually has a number of other great libraries that are part of the rendering stack. Notably, Pixie for text and shape rendering in 2D, Boxy for rendering textures to the GPU via opengl, and then Windy for an OS window context and user events, and a number of other libraries related to 3D rendering.

Perhaps not the "best" source code I've ever read, but libVF.io had some beautiful code for what's generally gnarly system-glue code. The iommu setup code is a good example and inspires me to think that system-glue code doesn't need to be gross or impenetrable: https://github.com/Arc-Compute/LibVF.IO/blob/master/src/libv...

Another one I've appreciated reading (and learned more about 2d graphics from) is Pixie, a 2d graphics library written in Nim. Here's the implementation of a fair subset of SVG paths: https://github.com/treeform/pixie/blob/master/src/pixie/path...

And one last one for basic algorithms: https://github.com/nim-lang/Nim/blob/version-1-6/lib/pure/al...

Of course Knuth's original code is still some of the best classic code. K&R's original C book is a classic.

I recently helped work on a new open source JPEG decoder in Nim. (Over here on GitHub: https://github.com/treeform/pixie/blob/master/src/pixie/file...)

This video was extremely helpful to understand the "why" of all the things the spec was trying to explain. It made a huge difference in us being able to get things working.

We talk a bit about JPEG and actually writing our decoder in Nim here: https://www.youtube.com/watch?v=vYwD7OynFcg

Overall, our concluding opinion is that JPEG has some extremely cool and really smart ideas for how to compress images but the binary file format itself has some very painful things in it (progressive and restart markers as a couple examples).

I am working on OpenStreetMap renderer in Nim - see https://github.com/severak/lunarender3/ (but work somewhat stalled)

I needed some language which is:

- compiled to binaries

- and really fast

- has needed libraries (HTTP server, protocol buffers, sqlite and image generation)

- it's easy to set up

It was nice experience and Nim simply worked for my needs. People on Nim forum were nice and helped me when I ran into problems. It has nice and usable built-in library and I was really impressed by graphic library pixie - https://github.com/treeform/pixie

I would use Nim again when I when I will see this application is suited for it (e.g. some command line apps).

> but not so small that there are no useful libraries written...

Says the person responsible for a ton of really useful, well-done Nim libraries, such as this amazing Cairo/Skia-like library: https://github.com/treeform/pixie#readme

Thank you for all the things you've made for Nim!

>As an example, AutoCodeRover successfully fixed issue #32347 of Django.

This bug was fixed three years ago in a one-line change.[0] Presumably the fix was already in the training data.

You should not test Django's own code — it's already been tested. For example, you don't need to write a test that checks if an object is retrieved with get_object_or_404 — Django's testing suite already has that covered.

Django is a high-level Python web framework that prioritizes rapid development with clear, reusable code. Its batteries-included approach supplies most of what you need for complex database-driven websites without turning to external libraries and dealing with security and maintenance risks. In this tutorial, we will build a traditional "Hello, World" application while introducing you to the core concepts behind Django.

If you want to get into Python web development then Django can be a good place to start. https://www.djangoproject.com/

In this Article, we create our own blog called CodeCraze using Django, a popular web framework written in python. Django is designed to help developers to rapidly build their web applications from concept to completion in an efficient way. Its a batteries included framework which provides out of the box functionalities such as ORM, API Integration, authentication, form handling & many more...

There are many models of access control, however, in this guide, we are going to focus on Role Based Access Control (RBAC) and how to implement it in Django.
