  • The PEPs of Python 3.9

    With the release of Python 3.9.0b1, the first of four planned betas for the development cycle, Python 3.9 is now feature-complete. There is still plenty to do in terms of testing and stabilization before the October final release. The release announcement lists a half-dozen Python Enhancement Proposals (PEPs) that were accepted for 3.9. We have looked at some of those PEPs along the way; there are some updates on those. It seems like a good time to fill in some of the gaps on what will be coming in Python 3.9

  • How to Write an Installable Django App

    In the Django framework, a project refers to the collection of configuration files and code for a particular website. Django groups business logic into what it calls apps, which are the modules of the Django framework. There’s plenty of documentation on how to structure your projects and the apps within them, but when it comes time to package an installable Django app, information is harder to find. In this tutorial, you’ll learn how to take an app out of a Django project and package it so that it’s installable. Once you’ve packaged your app, you can share it on PyPI so that others can fetch it through pip install.

  • Pros and Cons of Python: A Definitive Python Web Development Guide

    Python is a powerful programming language for mobile and web development projects. It is also the most popular programming language for AI in 2020. RedI Python development’s use cases in scientific computing, statistics, and education make it one of the highly preferred programming languages for Python programmers. The open-source programming language launched in 1992 is now on the verge of becoming the most popular and used programming language. Due to the rise in demand for AI and ML applications, Python web programming is now the first thing that comes to mind for coding such applications. But is Python for web development even worth it? It definitely is. Some of the top companies use Python web programming in their technology stack.

mesa 20.1.0

Hi all,

I'd like to announce Mesa 20.1.0, the first release for the 20.1 branch.

Being the first release of this new branch, there can be issues that
will be discovered now that the new code will be widely used, so you may
want to stay on the 20.0.x releases until the 20.1.1 release, scheduled
for 14 days from now on 2020-06-10.

One already known issue that I want to point out is that Unreal Engine 4
has a bug in its usage of glDrawRangeElements() causing it to be
called with a number of vertices in place of the `end` parameter,
that was recently revealed. This is an annoying bug that we haven't
worked around yet. For more details:
https://gitlab.freedesktop.org/mesa/mesa/-/issues/2917
